Abstract:
On the basis of cotton yarn and warp knitting, aiming at the problem that the mechanical properties such as cotton yaarn strength yarn strength at break and hairs were difficult to meet with the technical requirements of warp knitting, the solution to solve the technical problems of cotton yarns in warp knitting at high speed were proposed. It presented the key technologies of cotton yarns used in the warp knitting and provided the technical solutions among yarn spinning method, beaming and knitting processes. The compact yarns were selected, and the white oil was added when beaming-warping that can make the yarn hairs lodging to decrease the friction between the yarn and the loop formation elements. The cotton yarns were divided into two layers which could cut down the hairs' tangling. Finally, two warp knitted outwear products using cotton yarns were developed from the perspective of the warp structure and process design. The two-sided effect is obtained with cotton yarn as the partial weft insertion. The reason is that the front knitting guide bar and the back laying-in guide bar with cotton yarn underlap in the same direction,and the inlay evaded the knitting bar underlaps and slipped through onto the technical back of the structure. Warp twill is designed with cotton yarn as looping structure, whose guide bar is part-threaded.
Key words: cotton yarn, warp knitting, structure design, evasive yarn laying, two-sided effect, twill
