• development of textiles resistant to electromagneticradiation• development of textiles made of shape memory materials• development of textiles for ionex membranes• modifications of a ring fine spinning system anddevelopment of new yarn types• analysis of the material unevenness of linear and planartextiles in relation to the technology• development of laboratory methods and equipment foranalysis of nonstandard textile properties• fragile material processing5. Laboratories and special equipmentThe Department has two laboratories available:Textile Structure Laboratory4. Research activitiesThe research activity of the Department is performed underthe projects of the EU, Ministry of Education Youth and Sports,Ministry of Industry and Trade and economic activities mainlyin cooperation with Clutex, Sintex a.s. Česká Třebová, Stap a.s.Vilémov u Šluknova, VÚB a.s. Ústí nad Orlicí, VÚTS a.s. Liberec,MemBrain s.r.o. Stráž pod Ralskem. The main research activitiesof the Department are focused on:• modeling spinning, weaving and knitting processes andsystems and their optimization• modeling of the structure and properties of yarns, wovenand knitted surface textiles• modeling of the properties of PET and POP monofilaments,multifilaments and planar textiles made of these• development of software for predicting and optimizing theproperties of yarns and fibers including visualization• development of textiles with enhanced resistance tomechanical damage• development of active safety textiles with fiber-opticsThe laboratory is equipped with the image analysis forexamining the geometric parameters of textile structures.There were internal standards generated including software fordetermining the geometric properties of fibers, for measuringthe packing density, diameter and hairiness of single and plyyarns, for measuring tips on rotor yarns, inclination of surfacefibers, coverage of yarn core, for measuring the mixing quality(mixing index, testing the rate of aggregation of the sequencesof fiber components), geometry of fabric binding pointsincluding yarn deformation in the binding point and textileporosity. The laboratory is equipped with devices for measuringthe diameter, hairiness, material unevenness, yarn abrasion(Uster Tester 4-SX, QQM 3, Zweigle G 552, G 555, G 567), formeasuring filaments shrinkage (TST 2 Lenzing), measuring themechanical properties of textiles, such as tension, compression,shear (Instron 4411, Testometric M350-5CT), ball penetration,cut resistance (Testometric M350-10CT), air burst strength(EC 37), measuring the acoustic dynamic module of fibers andplanar textiles (DMT PPM5R Lawson Hemphill). The dynamicand mechanical properties are tested using the multi-functionaldevice (CTT Lawson Hemphill), where besides measuringthe material unevenness, number of thin places, thick places,neps, yarn diameter and hairiness, we can also measure thecross section profile of textured yarn, strength, elongation andshrinkage in dynamic mode, friction properties, abrasion andshare of short fibers in abrasion. There is also a prototype of theyarn compression measuring device available.8
Semi production laboratoryThe Semi production laboratory is focused on the assuranceof production of small parts of conventional and rotoryarns, ribbons, spliced cords, woven and knitted textiles.The machines are modified as required for the productionof textiles from special fiber. For spinning, it has a mini-lineavailable for production of conventional yarns that comprisesthe laboratory carding, drawing and ring spinning machine.The laboratory also has a winding machine and plying machine.It also has the rotor spinning machine available. The wovenfabrics are produced using the pattern mini-line from singlethread slashing and preparation of the warp single thread tothe pattern weaving loom. There is also the Jacquard, needleand ribbon loom. The knitting lab is equipped with weft- andwarp-knitting machines. The fabric weave is prepared for theJacquard loom using the Design Scope pattern software. Theknitwork pattern software can also be used.6. Grants and projectsThe Department employees take part in solving the followingselected projects:• Development of software for predicting woven propertiesincluding the setup of weaving loom parameters,ModSimTex Project 7 RP EU NMP2-SL-2008-214181 (2008-2011).
