Announcements: Chair Truesdale announced upcoming programs, the next one being
a workshop on Introduction to Textile Testing to be held December 6­7 at the AATCC
Technical Center. Truesdale also announced that AATCC is still offering Webinars and
eLearning Modules. Please check the web site for these, www.aatcc.org, and future
programs being offered by AATCC. It was also announced that the 2013 AATCC
International Conference will be held April 9­11, 2013 in Greenville, S.C. The C2C
Design Competition and the Materials Competition was also announced.

Nominations are now being sought for the 2014 TCR Service Award. The
deadline for the 2014 TCR Service Award is October 1, 2013. If you know of a
deserving senior individual member of AATCC, please submit the nomination by
October 1, 2013. You may access the criterion for this Award by clicking on
http://www.aatcc.org/general/awards/TCR.htm. You may also access the nomination
form at the same link.
RA23, Colorfastness to Water: The proposed revisions of AATCC Methods 15
(Colorfastness to Perspiration) and 107 (Colorfastness to Water) to add a note of
caution in each method regarding results obtained for staining was approved and will
now be submitted to a TCR Letter Ballot. A revision to TM 15 is being considered to
specify that a glass Petri dish be used in the procedure and to also list this item in the
Materials Section. The committee is still waiting on the statistical analysis of the two
oven types’ impact on TM 107. It should be completed and distributed prior to the
spring 2013 meeting. There was also a discussion of the acrylic plates used in TMs 15
and 107. There are no dimensions specified in the methods (width, length and
thickness). Lisa Earnshaw of James Heal and John Crocker of SDL Atlas will take
inventory of what they currently supply and report back to the committee. Concerns
were brought up also about the fact that the weight is specified but no pressure. It was
decided that it is best to keep the weight and the dimensions the same, as for auditors
and labs, as it would be difficult to specify the pressure. There was a question
regarding the expiration period of sea water solutions. Earnshaw has volunteered to
conduct a study by making a solution and testing it as the solution sits to see if there is
any impact on the results. There were still no volunteers for a new chair. Ellen Roaldi of
Bureau Veritas was nominated to continue to act as chair for 2013. This subject will be
brought up again in May 2013.
RA24, Fiber Analysis: The 2012 second round PT was reviewed for the PET/PTT and
Rayon/Cotton blends distributed. Mechanical separation variation was found to be
about ± 1%. Chemical separation variation was found to be about ± 4%. The 2013 first
round PT was determined to be Alpaca/Wool and Acetate/Spandex. Information to
support the addition of PBI will be sent to committee letter ballot so that this generic
class can be added to TM20 (Fiber Analysis: Qualitative) and TM20A (Fiber Analysis:
Quantitative) . Robina Hogan of Omni Tech International gave a very well received
PowerPoint on “Fibers Containing Soy Protein” and a Soy Fiber Subcommittee was
created with six members. Suggestions for the improvement of TM20A, Table 1,
provided by Seemanta Mitra of Intertek were reviewed and will be sent out to committee
ballot. In Method 9 of TM20A, the boiling point of methanol will be corrected to 65°C.
The Glass Fiber Subcommittee was renamed the Silica Fiber Subcommittee.
Incorporation of silica fibers into TM20 and 20A is being investigated. Ionic solvents
such as 1­3 Butyl­3­methylimidazolium chloride are being investigated for use in
TM20A. A Correction Factor of 1.046 for rayon will be added to TM20A. A statement
that "hair" fibers referenced in TM20A are synonymous with "specialty animal fibers or
non­wool fibers with scales on their surface" in Table 1 of TM20 will be added.

RA31, Antimicrobial Activity: It was reported that the participating labs in the Anti­
bacterial Proficiency Testing Program is down from 25 labs to 17. The next round of
testing is scheduled for April and October 2013. If anyone needs additional information,
contact Aaron Creech, AATCC, or go online at www.aatcc.org. The data from the
proficiency testing, if suitable, will be used to prepare a precision and bias statement
for TMs 100 (Antibacterial Finishes on Textile Materials: Assessment of) and 147
(Antibacterial Activity Assessment of Textile Materials: Parallel Streak Method). A
working copy of TM 30 (Antifungal Activity, Assessment on Textile Materials: Mildew
and Rot Resistance of Textile Materials) will be put online so that members will have a
working document to submit suggested changes. David Ramey is heading this project
and will work with the committee to make suggested changes. The possibility of a new
method for hydrophobic fabric has been dropped from RA31’s agenda due to lack of
interest. If anyone is still interested, they may prepare a draft and submit it to the chair
for review. Gina Sloan of Microban will now take the lead on the proposed new odor
method. She will draft a proposal in AATCC format and submit it to Bill Hanrahan and
Ramey for review. A proposed change to Method 100 to make it similar to ISO Method
20743, Absorption Method, was discussed. The committee decided not to change TM
100 since it is used worldwide, but will propose new method instead. A subcommittee
was formed to draft a new method, which includes Cheryl Laue of Wuxi Apptec,
Hanrahan, David Klein of Thomson Research Associates, Sloan, and Ramey. Beth
Joiner of NAMSA will submit a draft protocol to Hanrahan and Ramey. Sloan will see
what Microban has available. In other business, Joiner asked if the committee would
consider an adjustment to the wording and population range for TM 100 to say
“approximately” and change the population range from 1­2 to 1­5. Laue brought up that
purchased saline and phosphate buffered water have had a wide range of pH with
these media. She suggested that TM 100 should specify that the method say “buffered
saline” so that the pH would be around 7.0 instead of much higher or lower which could
affect test organisms. Hanrahan will send Laue a word document of TM 100 so that she
can include both proposed changes. These changes would then be balloted to the
committee. If any negatives are received at that stage, the changes will be retracted
and they would be included in the proposed new method the committee is developing.
It was brought to the committee’s attention that Part II of TM 30 does not provide
incubation parameters for the test samples and that they need to have some guidance
for an incubation temperature. Joiner will review the method to see if incubation
temperatures would be appropriate. The committee will address and make a correction
when TM 30 is again updated for reaffirmation. David Ramey was nominated as the
new chair of RA31 for 2013­2015. Joiner will remain as secretary.
RA33, Colorfastness to Atmospheric Contaminants: Distribution and fading of
samples using the new Disperse Violet Acetate Ribbon in TM 164 (Colorfastness to
Oxides of Nitrogen in the Atmosphere under High Humidities) is still needed. This
information is necessary to include it in TM 164 as it is in TM 23 (Colorfastness to Burnt
Gas Fumes). Production dyeing of Disperse Violet Ribbon for TM 23 still needs to be
completed so that samples from beginning/middle/end can be sent to participating labs
Page 3 of 11

in order for an average “standard of fade” to be determined and then subsequently
dyed. The product will then be ready for consumer distribution and sale, and a
precision and bias statement can then be prepared. Chris Webley of Limited Brands
has performed trials with TM 23 using polyurethane foam in order to determine if the
time of test can be decreased using higher concentrations of oxides of nitrogen and
increased temperature. Nine hour testing was reported instead of the normal 22­24
hours. The committee agreed this was promising and will look into this further.
RA34, Preparation: Katelyn Lee from Cotton Incorporated spoke to the committee on
“Enzymatic Preparation: Summary of Cotton Incorporated Evaluations Using DuPont
PrimaGreen® Products.” The Interlaboratory testing for TM 89 (Mercerization of
Cotton) to evaluate the neutral soap supplied by SDC as a replacement for the AATCC
neutral soap is not completed. The AATCC soap is no longer available. There was a
suggestion to consider inclusion of the use of accelerated solvent extraction (ASE) for
TM 97 (Extractable Content of Textiles). This will need to be investigated. A discussion
was conducted concerning the use of the “Shaker method” for testing for pH and
alkalinity. This would relate to TM 144 (Alkali in Wet Processed Textiles: Total). It was
not determined at this time whether or not a separate test method might be established
or whether a second part of TM 144 will be added. The chair will try to obtain a speaker
to discuss ASE methods and equipment for the May 2013 meeting. Editorial changes
for TM 81 (pH of the Water­Extract from Wet Processed Textiles) are continuing to be
reviewed and should be ready for a committee ballot before the May 2013 meeting.
There is interest in the potential incorporation of a near­infrared (NIR) method for
measuring barium number (degree of mercerization) for TM 89. This would be an
alternative method and not a method replacement for those who have access to a NIR
instrument. There were no volunteers to be the next chair of RA34.
RA36, Color Measurement: Method 110 (Whiteness of Textiles) was submitted to
another Committee Letter Ballot in October 2012. The deadline for this ballot is
November 26. The proposed draft for reactivation of TM 148, light blocking material for
curtains, was submitted to the committee for review only. Hopefully a proposed draft
will be sent to committee ballot prior to the next meeting. A subcommittee was formed
to study the illumination levels in EP9 (Visual Assessment of Color Difference of
Textiles). Work is continuing for the UV set point in EP11 (Spectrophotometer UV
Energy Calibration Procedure for Optically Brightened Textiles). EP8 (AATCC 9­Step
Chromatic Transference Scale) step tolerances need to be formalized. It is being
proposed to have interim RA36 meetings by WebEx in order to increase participation.
RA38, Colorfastness to Crocking: The recent committee ballot for proposed revisions
of TMs 8 (Colorfastness to Crocking: Crockmeter Method) and 116 (Colorfastness to
Crocking: Rotary Vertical Crockmeter Method), to also include the polyester/spandex
note, was approved. However, the note was inadvertently left out of the proposed
revision of TM 116. This will be re­balloted to the committee with the note in December
so that it may make the next TCR ballot. Daniel Sabou of Intertek indicated that the
crock cloth wetting procedure is not conducive to production testing. Sabou will provide
Page 4 of 11

the committee with wording for an alternate procedure. However, the committee feels
that the procedure as it is currently written is appropriate and it will be left that way for
now. There is still a concern of some members that the crock cloth pH tolerance is still
too tight at ± 0.5. The committee will consider changing it to maybe ± 1.0 or ± 0.75.
RA42, Dimensional Change: A proposed draft for a new method for dimensional
changes of socks and hosiery has been dropped from the committee’s work plan at the
request of The Hosiery Center’s representatives. As a follow up to questions about the
Precision and Bias for TM 179 (Skewness Change in Fabric and Garment Twist
Resulting from Automatic Home Laundering), Adi Chehna of Textile Tech Services had
drafted a relocation of 9.1.1.2 recording negative and positive mathematical test results
to the Report Section of the method. A motion was made and approved to send this
revision to a committee ballot. Further discussions about the Precision and Bias data
set brought further suggestions about making the instructions for calculations of test
results another committee ballot to change the wording in 9.1.5 to add “the average of
the absolute values of the results will be reported.” The motion was made and
approved to send this forward. The committee agreed that the Precision and Bias data
was too questionable and that the method needs to have a multi­lab Precision and
Bias. A task group was formed to start work on a new P&B interlab study. Labs that
have agreed to participate in the study are: Natick, REI, Cotton Incorporated, The
Hosiery Center and AATCC. Testfabrics has agreed to provide candidate fabrics that
will be tested by Cotton Incorporated using Option 1 (1 x 3 Laundering at Normal wash
and dry settings) to determine which fabrics will be selected for the study to insure a
range of skew performance. Chehna, Angela Massengill of Cotton Incorporated and
AATCC volunteered to develop the interlab protocol. The goal is to have the fabric
screening and protocol developed by mid­February 2013. Chehna pointed out that the
discrepancy between the instruction for specimen preparation for tubular knits in
Methods 135 (Dimensional Changes of Fabric after Home Laundering) and 179 is a
source of confusion for some users. A motion was made and approved that the wording
in TM 135 be inserted in TM 179. This change will be submitted to committee ballot.
Chehna volunteered to be the next chair of RA42 and Stacy Cain of Intertek
volunteered to be secretary. Susan Gassett of Natick informed the committee that a
wash wheel manufacture was not found.
RA43, Professional Textile Care: Joseph Nilsen of DLA, and acting chair of RA43,
gave excerpts from a National Clothes Line Article published in August 2011 about
alternatives to Perchloroethylene and the results of a European study.
RA45, Finish Analysis: It was announced that the TCR ballot to merge RA68, Odor
Determination, with RA45, Finish Analysis, using RA45’s scope, was approved. The
two committees are now officially labeled as one under RA45, Finish Analysis Test
Methods. The committee reviewed the proposed draft for a new method on Immersion
for Formaldehyde Determination. Additional changes will be made and another draft
will be sent to the committee for review prior to a committee ballot.

RA49, Insect Resistance: The recent TCR letter ballot for proposed reaffirmation of
TM 194­2008 (Assessment of the Anti­House Dust Mite Properties of Textiles under
Long­Term Test Conditions), received two comments with affirmative votes. One
comment is being addressed. George Antunes of Miratex, and chair of RA49, gave a
quick overview of the proposed new test method on Active Ingredient ‘a.i’ Activity on
Textile Surface, which was discussed at the May meeting. The proposed draft will be
submitted for a committee letter ballot after a precision and bias is revisited to obtain
applicable data.
RA50, Lightfastness and Weathering: TM 125 (Colorfastness to Perspiration and
Light) was recently sent to committee ballot and received some comments which were
deemed technical. These changes were made and then submitted to another
committee letter ballot. Once again it received another negative. The negative voter
wanted a definition of “plastic wrap.” The negative voter has agreed to withdraw his
negative if a note saying the film must be transparent film (such as food grade wrap) is
put in the method. The committee has agreed and this item will move forward to a TCR
ballot. The chair announced that AATCC has a year’s supply of L4 and two years of the
L2 in stock. The small scale samples of a new fabric to replace Blue Wool seem to be
repeatable. Larger samples will be made and sent to four labs to check prior to making
a bulk production. Richard Slomko of Atlas Material Testing Technology gave an
update on ISO 105 B02.
RA56, Stain Resistance: A committee letter ballot was submitted for revision to TM
118 (Oil Repellency: Hydrocarbon Resistance Test) to establish CAS numbers and
appropriate attribute specifications for heavy mineral oil to allow for generic sourcing.
This was approved and will now be submitted to a TCR ballot. A survey to find the
range of hardness, pH and other water variables was discussed for TM 130 (Soil
Release: Oily Stain Release Method). It will be requested for labs to submit their
specific water hardness for their labs. Mark Granja of Sun Products will provide AATCC
with water hardness concentrate for AATCC to create various levels of known
hardness. Granja will provide guidance on the amount of 200,000 ppm concentrate to
adjust DI water. New scales used in TM 130 needs to be created. New examples of a
proposed AATCC Stain Release Replica will be distributed to volunteers to select the
five “best fits” consistent with what is observed in the industry. Suzanne Holmes of
AATCC will lead a subcommittee with Erika Simmons of Hanesbrands, Paul Johnson of
3M Co., and Angela Massengill of Cotton Incorporated. There were no volunteers for
the new chair. Johnson was re­nominated as chair for 2013­2015. Granja will remain as
secretary.
RA57, Floor Covering: An improvement of the AATCC Red 40 Stain Scale was
presented to the committee and were well received. AATCC will print the final format
and send to Alan Buttenhoff of Shaw Industries, and chair of RA57, for industry
approval. The printing of the scales will reduce manufacturing time at AATCC and
improve acceptance. Regarding Moisture Penetration, Chris Leonard of AATCC
updated the committee on his research into the intellectual property (IP) holders of the
Page 6 of 11

original test (British Health System). Leonard informed the chair of needed changes in
the proposed method and the direction he needs to take in future conversations with
the IP holders.
RA59, Fibrous Test Materials: Testfabrics is investigating the possibility of new single
fiber adjacent fabrics. Initial samples will be tested by SDL Atlas, James Heal, and
Intertek. Some initial work has been done on the acetate adjacent fabrics, but more
needs to be done. Testfabrics will be distributing more fabrics to labs for study. A
question was raised regarding dyestuff and soap powder for EP10 (Multifiber Adjacent
Fabrics: Evaluation of). Dyes are available from AATCC. Chris Leonard of AATCC will
research and update the committee further in May. The polyester/spandex boiler
statement was reviewed.
RA60, Colorfastness to Washing: RA60 sent to committee ballot a proposed revision
of TM 61 (Colorfastness to Laundering: Accelerated), to include the boiler plate
statement regarding polyester/spandex. The CLB received a negative which has since
been withdrawn. This proposed revision can now be submitted to TCR Letter Ballot. A
trial study was done with TM 61 using the 105°F option comparing TM 61 and TM 188
(Colorfastness to Sodium Hypochlorite Bleach in Home Laundering) to see whether a
45 minute wash still equals five home launderings. Data has been collected and are
currently being analyzed by the Statistics Advisory Board. Proposed drafts of the quick
bleach methods, chlorine and non­chlorine, were send to RA60 members for comment
prior to sending to committee ballot. Daniel Sabou of Intertek had asked us to discuss
quick bleach concentrations but unfortunately he could not attend. This item will be
carried over to the May meeting. Assessment of color block fabrics in home laundry test
was discussed and it was decided to put the question on LinkedIn and ask for input
about any local methods in the industry.
RA61, Appearance Retention: An interlab to compare the 4 and 8 lb loads for
Methods 88B (Smoothness of Seams in Fabrics after Repeated Home Laundering),
88C (Retention of Creases in Fabrics after Repeated Home Laundering), 124
(Smoothness Appearance of Fabrics after Repeated Home Laundering) and 143
(Appearance of Apparel and Other Textile End Products after Repeated Home
Laundering) was organized with AATCC, Natick, Cotton Incorporated, Intertek and FITI
participating. Garments were sent out for testing and were discussed at the November
meeting. The statistical analysis is being performed by Krishna Parachuru of Georgia
Tech, chair of RA102, and will be ready by the May 2013 meeting. Ken Greeson of
Cotton Incorporated, chair of RA61, mentioned that an interlab will be conducted
involving the use of an automated CRA tester (TM 66, Wrinkle Recovery of Woven
Fabrics: Recovery Angle). Greeson is working on a protocol and interlab study
procedures.
RA63, Water Resistance, Absorbency and Wetting Agent Evaluation: A proposed
reaffirmation of TM 127 (Water Resistance: Hydrostatic Pressure Test) was submitted
to a recent TCR Letter Ballot and approved for the 2014 AATCC Technical Manual.
Page 7 of 11

Further discussion of TM 127 proposed to restrain materials with membranes that may
stretch. An interlab was discussed for the proposed 1 mL Drying Test. The study will be
repeated with additional new samples. Additional interlabs are planned for TMs 195
(Liquid Moisture Management Properties of Textile Fabrics), 197 (Vertical Wicking of
Textiles) and 198 (Horizontal Wicking of Textiles). The Repellency subcommittee is
working on a rewrite of text for TM 35 (Water Resistance: Rain Test). The
subcommittee needs more clarification about the statistics report on TM 35 and TM 42
(Water Resistance: Impact Penetration Test). The Moisture Management
Subcommittee discussed proposed changes to TM 199 (Drying Time of Textiles:
Moisture Analyzer Method) and interlabs. The committee discussed water impacts on
down and work at International Down and Feather Laboratory (IDFL). No work is
anticipated by AATCC. The committee discussed RA75’s correlation study between
AATCC lab tests and actual wear. Jessica Farrell of Cotton Incorporated was
nominated as the new chair of RA63 for 2013­2015.
RA75, Evaluation of Materials and Products for End Use Performance: The field
testing correlation subcommittee is waiting on confirmation of mill and factory partners.
A next­to­skin top will be half­treated and half­untreated for moisture management.
Technology has not been determined; but the lab tests have been defined and the field
test protocol is in draft stage. Adi Chehna of Textile Tech Services presented
information on label staining. Disperse dye remains on Spandex fibers and transfers to
polyester labels. Standard tests do not predict the problem. The combination of fabric
and environment (exposure to oil) creates the problem. Chehna would like a note of
caution to be added to test methods for crocking, perspiration, water and storage to this
effect. The crocking and washing committees have already submitted ballots for their
methods. Additional tests may be developed.
RA80, Printing Technology: Brad Belk of Axiom America provided an overview of
digital direct to garment printing technologies and process. The committee briefly
discussed the number of webinar sales for “Digital Printing, Part I” and the potential for
running an update to this session during 2013. Also, digital print topics for the 2013
AATCC International Conference were highlighted.
RA87, Applied Dyeing Theory and Characterization of Dyes: Proposed reaffirmation
of TMs 167 (Foaming Propensity of Disperse Dyes) and 141 (Compatibility of Basic
Dyes for Acrylic Fibers) were submitted to a TCR Letter Ballot and were approved for
inclusion in the 2014 AATCC Technical Manual. Work needs to be done on low
temperature dispersion filter test method option in the next review cycle. Mir Quddus of
Whirlpool brought up the need for a test method of wet abrasion dye transfer under
laundering conditions (with detergent solution). There was a discussion on the current
TM 8 (Colorfastness to Crocking: Crockmeter Method) and need to show closer
correlation to actual laundering in machine. The need for a joint symposium with
Concept 2 Consumer® and Materials Interest Groups, etc., on dye/coloration was
discussed. Also, maybe a joint symposium on fastness issues with laundering machine
manufacturers (i.e. Whirlpool), detergent manufacturers, dye companies and textile
Page 8 of 11

companies could take place. The chair will try to obtain a speaker on safety
implications to dyeing–new global harmonization of safety data sheets (SDS). Tom
Klaas of Testfabrics said he could get independent dye testing done (using AATCC)
like dispersion filter test, etc., and could help companies screen new dyes. It was
reported that American Apparel and Footwear Association (AAFA), and other
supporting companies, have come out with a new “industry standardized” Voluntary
Product Environmental Profile (VPEP) form. Brian Dill of Clariant was nominated to be
chair for the 2013­2015 and Bert Truesdale of TenCate will be secretary.
RA88, Home Laundering Technology: Mir Quddus of Whirlpool, and chair of RA88,
announced that the programmable washer subcommittee did not meet so there was no
update to report. Quddus reported that the revision to the 2012 monograph has been
approved and will appear in the 2013 AATCC Technical Manual. It can be accessed
now on the AATCC website. Chris Leonard of AATCC gave an update to the
communication with the Federal Trade Commission (FTC) and the Consumer Product
Safety Commission (CPSC). Leonard and Jack Daniels of AATCC visited the CPSC
and gave a presentation about the changes in the washing machine industry and the
introduction of the key dance cycle. The CPSC has been using the TM124­2006
version and is looking internally on how to deal with the many changes in the washing
machine industry while maintaining control of what is being tested. Jacqueline
Campbell of the CPSC encouraged AATCC members to communicate with the CPSC
either individually or through AATCC to let the CPSC know how their business is
affected when standards and washing machine parameters are not harmonized.
Campbell encouraged members to comment on the FTC care labeling rule which is
open for comments until November 16, 2012. The survey on washing cycle usage was
reviewed by Quddus. The objective was to see if the committee could remove either
“cold” or “cool” in the temperature tables to provide simplicity. It was estimated that the
majority of care labels are “wash cold” so it is important that these temperatures are
reviewed properly. The survey had a limited number of respondents (17 for top loaders,
and less for front loaders). Due to the low number of responses, it was suggested that a
new survey be submitted to the broader AATCC organization. Suggestions for
modifying the survey include: removing “warm” and “cold” labels and using only
temperatures, asking each lab to report their cold tap temperature (realizing that it will
be different in the summer months), and asking what methods are most commonly
used. Karen Kyllo and Lou Ann Spirito of SGS, Campbell and Gary Childers of Procter
& Gamble agreed to help review the new survey before it is distributed. Results of this
survey will help to develop the 2014 monograph. Quddus showed a short video on how
the key dance feature will work. Models with the key dance feature are estimated to be
available September­October 2013. AATCC has requested a prototype prior to market
rollout. Quddus reported the suggestion of a new dye transfer (crocking) method for low
water level washing. Current methods do not address this and he is working with RA87
to create a method. It was suggested by Leonard to include RA60, Colorfastness to
Washing, in this work as well.

RA89, Hand Evaluation: The committee has agreed to remove from its work plan
efforts to develop standard hand samples at this time. Roger Barker, Burlington
Distinguished professor and Director of TAPCC, College of Textiles at North Carolina
State University, gave a presentation on a study “Fabric Hand in Relation to Human
Tactile Response to Garments in Dynamic Wear.” The study, in conjunction with
industry partners, investigated Kawabata data and wear trial responses as predictors of
comfort. Robert Lattie of SDL Atlas volunteered to make a presentation at the May
2013 meeting about their new instrument for fabric hand developed with Hong Kong
Polytechnic University.
RA99, Technical Manual Editorial Review Board: The cautionary note for
polyester/spandex fabrics was balloted in Committees RA38 (Colorfastness to
Crocking) and RA60 (Colorfastness to Washing), and will now be balloted in TCR. The
same note will be balloted to add the statement in TM 163 (Colorfastness: Dye Transfer
in Storage; Fabric­to­Fabric).
RA100, Global Sustainability Technology: Ruth Lunn of NIEHS gave an overview of
the “12 th Report on Carcinogens.” Seshadri Ramkumar of Texas Tech University gave a
presentation on “Sustainable Cotton Value Added Products and Processes.” It was
announced that the Federal Trade Commission Green Guides have been released.
The California Green Chemistry proposal was released and comments were taken in
September 2012.
RA102, Statistics Advisory: Proficiency data gathered for the following list of methods
has been analyzed and discussed: TMs 22 (Water Repellency: Spray Test), 35 (Water
Resistance: Rain Test), 42 (Water Resistance: Impact Penetration Test), 100
(Antibacterial Finishes on Textile Materials: Assessment of), 127 (Water Resistance:
Hydrostatic Pressure Test), and 147 (Antibacterial Activity Assessment of Textile
Materials: Parallel Streak Method). The chair is checking on agreement between TMs
61 (Colorfastness to Laundering: Accelerated) and 188 (Colorfastness to Sodium
Hypochlorite Bleach in Home Laundering). Proficiency data of the following test
methods for years 2009, 2010, 2011 and 2012 will be analyzed for the next meeting:
TMs 8 (Colorfastness to Crocking: Crockmeter Method), 15 (Colorfastness to
Perspiration), 61 (Colorfastness to Laundering: Accelerated), 88B (Smoothness of
Seams in Fabrics after Repeated Home Laundering), 88C (Retention of Creases in
Fabrics after Repeated Home Laundering), 107 (Colorfastness to Water), 124
(Smoothness Appearance of Fabrics after Repeated Home Laundering) and 135
(Dimensional Changes of Fabrics after Home Laundering). Proficiency data for
appearance retention and colorfastness to washing method are in the process of being
analyzed.
RA103, Spectroscopic Technologies: James Rodgers of RU USDA ARS, current
chair of RA103, has agreed to serve as acting chair for 2013 and Keith Beck of North
Carolina State University will remain as secretary. Frederic Prulliere, Business
Page 10 of 11

Development Manager for the Out of the Lab group at Agilent Technologies presented
a talk about handheld and small portable FTIR instruments. After a brief history of
infrared spectroscopy, Prulliere demonstrated two different instruments offered by
Agilent. The handheld instrument weighs less than two pounds, is very robust and
designed to be used in the field. It has been employed by first responders to identify
hazardous materials. Because of the time limit for the meeting, the very active
discussion and demonstration was moved to the area outside the room. The talk was
excellent and very timely.
RA104, Garment Wet Processing Technology: LouAnn Spirito of SGS gave a
presentation on “Got Checklist? What’s New Prop 65 & Compliance: What You Should
Know­Impact, Challenges and Mitigating Risk.” Heidi Woodacre of Rothtec Engraving
Corp. noted that the committee was still looking at having a symposium in Canada.
Woodacre, also on the Education Advisory Board, stated it was discussed to possibly
