Dry nonwovens are generally used for
large-particle use in the form of panels
or rolled filters. Washable and disposable
types are available. For middle or
high-efficiency filters, glass fibre nonwovens,
dry nonwovens of fine fibres,
wet nonwovens, meltblown nonwovens
and electret nonwovens are common
materials, and take shape of bags or
“fold-in” units. These filters are normally
single-use only, but as ultrasonic
cleaning technology advances, reusable
filters are under review. Extremely high
efficiency type particulate air (HEPA) or
ultra low penetration air (ULPA) filters
have appeared in household air conditioners
and air purifiers. Like middle
and high efficiency types, pleated filters
are folded into the unit.
The Travelon air filter range from
Kanai Juyo Kogyo KK, Japan, emphasises
resource-saving and environmental
protection. Travelon pre-filters include
halogen-free filters and heat resistant
types for dryers in car paint-shops. For
middle/high-efficiency grade, filters
with large air capacity and small depth
size are available, saving space and
extending filter life. Gas-removal filters
for semi-conductor manufacturing, Pure
Home N and H, have been launched in
cooperation with Nihon Pure Tech.
Anti-bacterial filters are also available.

Production and demand for synthetic
fibre and thread in the world and in
Russia
From data based on the year 2000, the
demand for all types of textile fibre was
about 48mt but by 2003 it will have
risen to 50mt (28.7mt of chemical fibre
and 26.4mt synthetic). Among the
regional leaders, China is the foremost
in the area of chemical fibre. In North
and South America, West Europe,
Africa and the Middle East the development
will be moderate. A world textile
market is awaited in 2010. There is a
lowered demand for cotton, for example
from 2000-2010 from 38 to 32%.
Statistical tables give a break-down of
world supply and demand for textile
fibre and chemical fibre; the output of
synthetic fibre in the world giving the
share contributed by Asia; the USA production
is shown for chemical fibre, cotton
and wool; the properties of basic
reinforced fibres and lastly the share of
demand for cars, carpets, furniture,
office materials, textiles and knitting
wool, material and technical needs. (16

The future development of the markets
of natural raw material in Russia
The textile industry, which supplies
the market with goods for consumer
demand and a significant volume of
products which are used in all branches
of the economy for technical specialist
and medical section, clothing
stock for the Russian army and
Ministry of Internal Affairs and budget
organisations in the period 1999-2000
has a stable growth of production. For
example, in the southern districts of the
Russian Federation in recent years
good results have come from cotton
grown in the experimental sector. A
small group of enthusiasts among
agronomist and professors have created
the first Russian fast-grown cotton
using ecologically clean technology,
and the quality satisfies the Russian
textile industry. With the active participation
of a section of enterprise, a fund
has been formed to accumulate the
means to resolve problems of technology
and the development of the raw
material base such as selecting new
kinds of flax. Russia must work boldly
on the assortment of competitiveness
and liquidity of the internal and external
markets.

Fleissner sells seven AquaJet spunlace
machines in first half
The shipment of seven machines to
Western and Eastern Europe, the Middle
and Far East and South America in the
first half of 2001 raised Fleissner’s total
output of AquaJet spunlace machines to
more than 40. The units produce one-layer
smooth, perforated or structural nonwovens
as well as composite and sandwich
pulp/tissue constructions. (Short article)

JM Europe starts up new spunbonded
polyester line
Johns Manville GmbH, Germany, has
commenced production on a new
DEM30m line to meet the growing
demand for spunbonded polyester tissue.
Johns Manville acquired the Berlin-
Zehlendorf plant from Hoechst Trevira
in 1999. The new 2.50m wide line uses
jet technology to form 1-12dtex fibres,
allowing more even, higher strength
nonwoven tissues to be produced. The
product range now includes tissues of
less than 15gsm substance. The new
CombiFil multilayer spunbonded filter
materials comprise both fine and coarse
polyester filaments, the fine surface filaments
improve particle retention with
the coarse filaments ensuring minimum
pressure loss.

Concert’s turnover is ahead of schedule
Concert’s new DEM130m Prignitz,
Germany, plant has raised its turnover
from DEM28.9m in 1999 to DEM85m
in 2000. A further 18% increase is
expected for 2001. End uses for its
28,000tpy airlaid tissue production
capacity include feminine hygiene and
incontinence products, as well as wipes
and absorptive pads for meat packaging.
The global market for airlaid products is
expected to show double digit growth
rates. The Concert Group’s total produc-
