Abstract:

In order to solve artificial sewing and high production costs required by conventional socks, the V-bed computerized flat knitting machine and SDS-ONE APPEX3 design system was adopted to study the whole socks from pattern design, process parameters and knitting process. According to the sox head structure, the whole socks in common socks, toe socks and inner toe socks were proposed. The knitting technology of every part of whole socks was discussed. Three kinds of sox head knitting technology were discussed emphatically. It is found that sox head adopts partial technology to realize the circular shape and spacer knitting of inner toe socks. During the knitting process of sox foot and tube, the horizontal dimension change of the cylinder can be realized by the narrowing and widening process. The sox heel forms a trapezoidal bag structure by partial technology and narrowing and widening process. The sox mouth adopts a rib structure and inserts elastic yarn to prevent slipping when wearing. The final treatment of sox mouth adopts a press-off process.

Key words: flat knitting, whole socks, process design, knitting principle
