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.

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.

In this paper, welt knitted fabric reinforced composites were fabricated and its tensile properties were measured. Changing knitted structure from plain knit to welt knit caused changing mechanical properties, particularly isotropic tensile strength could be obtained. The fracture mode of welt knitted fabric reinforced composite was similar that of plain knitted fabric reinforced composite.

The main content dealt with in the paper is to present a kind of weft-knitted spacer fabric with high porosity. It is a kind of three-dimensional textile fabric with a sandwich structure that consists of a middle layer of multifilament and two outer layers of plain-knitted fabric. Compared with traditional warp-knitted spacer fabric as cushion mats, weft-knitted spacer fabric is well used as apparel for good softness, thermal/moisture comfort, and air permeability. Therefore, three structures were designed and nine samples were prepared by choosing plain-knitted fabric as the outer layers and selecting soft and thin multifilament as a middle layer. Experimental results show that this kind of weft-knitted spacer fabrics has high porosity, greater than 86%, and also demonstrate that the weft-knitted spacer fabric is suitable for comfortable apparel based on experimental results of air permeability, compression properties, stiffness, and thermal insulation properties.

Cotton Yarns

The necessity and aims of studying dimensional and geometric properties of a plain loop made of rotor spun cotton yarn are discussed after critically assessing the state of knowledge in the available literature. The underlying considerations for the design of the experiments as well as the details of experimental materials and methods are also described. The results are discussed in subsequent parts of this series of papers.

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.

The knittability of basalt fiber yarn for knitted fabrics was estimated from two aspects. Firstly the effect of 3 kinds of head size of needle hook on the loop strength of basalt fiber yarn was analysis by the experimental data. Then the basalt fiber yarn was knitted into plain, 1*1 rib and all needle rib knitted fabrics in 5 different loop lengths in a flat knitting machine. The influence of loop length, fabric stitch and fiber fineness on the fiber damage degree were studied by means of the tensile strength of the yarn taken from the fabrics for all kinds of fabrics. The experimental results show that for these 3 kinds of basalt weft knitted fabrics there is a best loop length in which the fiber damage degree caused by the knitting process is the smallest and the value is different for each stitch.
