The coefficients of variation-length curves for yarn twist and linear density have been determined for polyester/cotton yarns spun by ring, rotor, and friction processes as a function of blend proportion, yarn twist, and yarn linear density. The influence of each of these parameters on twist and linear density irregularity is described according to the spinning process. The coefficients of variation length curves can be mathematically represented with sufficient accuracy by a polynomial expression including first-and second-order terms.

The functionality of textiles can be complimented by using a wide variety of modification technologies. This study focuses on textile modification with sol-gel technology as a part of smart sock prototype development. Zinc acetate dehydrate (ZAD) is integrated in sol synthesis and used as modifier thus improving modified cotton yarn mechanical properties and also can prolong time between washing, taking into account modifiers antimicrobial properties. Four hanks of pure cotton yarns with length of 300 m, where modified with silica-based sol with 7,5 wt% ZAD as a modifier. As a part of this study tensile strength and elongation of yarn was determined and changes in liner density were observed. Average yarn linear density increases by 19 % and linear density for knitted samples increases by 2,6 %. Therefore, yarn strength for 80 % of modified samples shows mean value of 2,32 N, that is 17 % higher than unmodified samples.

Cotton Yarns

The data on loop length generated in the course of these experiments have been analyzed to establish the effect of yarn linear density and twist factor as well as machine gauge and cam setting on the dry relaxed loop length. The effects of cam setting and sinker spacing have been quantified by empirical relations.

An analysis of experimental data on plain knitted fabric dimensions reveals that the area ( Ks) and linear ( Kc, Kw) parameters are not tenable propositions, at least for rotor spun cotton yarns. Fabric dimensions are shown to depend not only on loop length but also strongly on tightness factor and relatively weakly on machine gauge and yarn linear density.
