Namen diplomskega dela je ugotoviti vpliv lastnosti air-jet preje iz mešanice bombažnih, poliamidnih in poliestrnih vlaken na uporabne lastnosti tkanine. V prvem delu raziskave so obravnavane mehanske in fizikalne lastnosti air-jet preje iz CO/PA in CO/PES vlaken, dolžinskih mas 15,8 tex in 16,8 tex. V nadaljevanju so raziskane tudi mehanske lastnosti tkanine, izdelane iz air-jet preje v votku. V drugem delu raziskave je večja pozornost namenjena prepustnostnim lastnostim tkanin z air-jet prejo v votku. Med pomembnejše prepustnostne lastnosti sodijo prepustnost vodne pare, zračna prepustnost in toplotna prevodnost, ki so zelo pomembne z vidika udobja. Za primerjavo je bila izdelana tkanina iz bombažne prstanske preje v votku dolžinske mase 14,6 tex. Rezultati raziskave so pokazali, da prisotnost air-jet preje v tkanini vpliva na mehanske lastnosti tkanine v smeri votka. Tkanini, ki v votku vsebujeta CO prstansko prejo (tkanina 1 in 2), imata v smeri osnove in votka večjo pretržno napetost kot ostale tkanine, ki imajo v votku air-jet prejo (pri enakih gostotah). Tkanini s CO/PA air-jet prejo v votku (tkanina 3 in 4) pri isti gostoti izkazujeta večjo pretržno napetost in raztezek v primerjavi s tkaninama, ki imata v votku CO/PES air-jet prejo (tkanina 5 in 6). Tkanini s CO/PA air-jet prejo v votku imata proti pričakovanju tudi manjši elastični povratek kot tkanine, ki imajo v votku CO prstansko in CO/PES air-jet prejo. Tkanine z air-jet prejo v votku imajo večjo toplotno prevodnost in prepustnost vodne pare ter manjšo zračno prepustnost v primerjavi s tkaninama, ki v votku vsebujeta CO prstansko prejo.

• Title: Impact of air-jet yarn from a mixture of CO/PA and CO/PES fibers on the useful properties of a woven fabric

Abstract

The purpose of this diploma thesis is to determine impact of cotton, polyamide and polyester spun air-jet yarn on the useful properties of woven fabrics. In the first part of the study mechanical and physical properties of air-jet yarn made of cotton-polyamide (15,8 tex) and cotton-polyester (16,8 tex) are researched. Further on, also mechanical properties of woven fabric made of air-yet yarn are researched and discussed. The second part of the study is primarily focused on transmission properties of the fabric with air-jet yarn in weft. Considering comfort, thermal conductivity, water vapor transsmision and air permeability are the most important transsmision properties. To compare all listed properties, an additional fabric woven with cotton ring spun yarn (14,6 tex) was produced. Results have shown that the presence of air-jet spun yarn in fabric has changed the mechanical and physical properties of fabric itself. Fabric 1 and 2 made of CO ring spun yarn in weft have a higher tensile strenght in the direction of the weft and warp, than all other fabrics with air-jet spun yarn in weft (at the same fabric density). Fabric 3 and 4 with CO/PA air-jet yarn in weft have shown a higher tensile strength and extension when compared to fabric 5 and 6 with CO/PES air-jet yarn in weft (at the same fabric density). Contrary to expectations, the results of fabric with CO/PA air-jet yarn in weft have shown a lower elastic recovery than the fabric with CO ring spun yarn in weft. Fabrics with air-jet yarn in weft have higher thermal conductivity, water vapor transmission and a lower air permeability in comparison to fabric made of CO ring spun yarn in weft.
