Sažetak
Cellulose is a raw material with a wide variety of uses in the chemical industry for producing man- made textile fibers. Conventional regenerated cellulosic fibers are generally produced by the indirect viscose process (viscose fibers), while high-tenacity modal fibers are produced using a modification of the basic procedure. Viscose production is based on deriving cellulose with carbon bisulphide. Lyocell fibers are produced by a more environmentally friendly procedure from a solution of non-derivative cellulose in a solvent spinning process, where cellulose is dissolved directly in the organic solvent N- methylmorpholine-N-oxide, without the formation of derivatives. Different production processes cause differences in the structure of the fibers despite the same chemical composition. Knitwear that are worn in direct contact with the skin, are often made of viscose, modal or lyocell fibers, that provide silky touch, high hydrophilicity and exceptional comfort. They were usually knitted with spun yarns produced by conventional ring spinning system. More recently unconventional rotor and air-jet spun yarns have been appeared, resulting with yarns of different structure and properties. Therefore, in this paper circular weft double jersey knitted fabrics for lingerie made od single ring, rotor and air-jet spun yarns, all made of bright staple viscose, modal and lyocell fibers of the same linear density were evaluated. Raw and finished knitwear usage durability were compared by determination of moisture regain, breaking strength and breaking elongation, dimensional change after laundering, air permeability, propensity to surface piling and abrasion resistance, all according to the standardized test methods.
