Abstract
A double-bed circular knitting machine with a gauge of E17 and a needle bar diameter of 200 mm (8 in) was used to make three groups of plain weft knitted Tencel fabrics and three groups of modal knitted fabrics. The yarns were spun using three spinning methods: ring, rotor, and air-jet system. Their count was 20 tex. All the knitted fabric samples were manufactured under the same conditions. One-half of each knitted fabric sample remained unfinished, while the other half was finished. Structure parameters of all finished and unfinished knitted fabrics were analyzed, and the most significant parameters were compared. Tensile properties of the knitted fabrics in wale and course directions were measured. The difference in the elasticity of the knitted fabric was analyzed in particular, and the portions of knitted fabric stretch are given. The basic conclusion is that using equal yarn fineness, but different raw material composition and structure, the produced knitted fabrics had substantially different fabric masses per unit area. The raw material composition and construction of the yarn, that is, the yarn manufacturing process and the spinning process produce yarns of different structures and properties that are manifested in the structure and properties of the knitted fabric. Thus, the finishing process must be specific for each raw material composition and yarn structure.
Highlights
Not long ago, both men’s and women’s cotton underwear was worn almost exclusively
The criteria for the manufacture of individual garments, and of outerwear and underwear are distinguished. This is the reason why double jersey fabrics made of Tencel and modal yarns are compared. This kind of knitted fabric often adheres to the body skin; in their manufacture special attention should be paid to raw material composition, structure and count of yarn, knitting machine gauge as well as to knitting and finishing conditions.[11,12]
For the finished modal knitted fabrics made of the yarns spun on the ring spinning machine (MR), the mass per unit area determined by weighing knitted fabric samples and using the equation was the same, amounting to 158 g/m2
Summary
Both men’s and women’s cotton underwear was worn almost exclusively. For a number of reasons, new fibers and yarns have been offered lately, and with them various woven and knitted fabrics. It is understandable that such fibers and different spinning processes will produce significantly different structures and properties of yarn, suggesting that particular attention should be paid to their manufacture and finishing of knitted fabrics (see Figure 1).[4,8,9]. The criteria for the manufacture of individual garments, and of outerwear and underwear are distinguished This is the reason why double jersey fabrics made of Tencel and modal yarns are compared. This kind of knitted fabric often adheres to the body skin; in their manufacture special attention should be paid to raw material composition, structure and count of yarn, knitting machine gauge as well as to knitting and finishing conditions.[11,12]. The finished knitted fabrics were folded and stored for further investigations
