Double-sided differential knitted fabric and its weaving process

Abstract

The invention relates to a double-faced differential knitted fabric and a weaving process therefor, and belongs to the technical field of knitting. The double-faced differential knitted fabric is composed of a front surface and a back surface, wherein the back surface is formed by low needle level weaving; and the front surface is formed by high needle level weaving or low and high needle level hybrid weaving. The process is applied to the operations of weft knitting weaving and the like, so that the operations are stable, fabrics with different densities can be weaved, and a raised line effect with concave-convex change can be achieved.

Description

technical field [0001] The invention relates to a double-sided differential knitted fabric and its weaving process, belonging to the technical field of weaving. Background technique [0002] Knitted fabrics are divided into weft knitting and warp knitting. The vertical and horizontal extensibility of weft knitting fabrics is better than warp knitting, and the production process and production equipment of weft knitting are simpler than warp knitting. Weft knitting can directly produce finished clothing, while warp knitting only It can produce fabrics, so weft knitting applications are more common. [0003] In weft knitting, the most commonly used weaving element is the needle cylinder. The conventional needle cylinder is composed of an upper needle cylinder and a lower needle cylinder. The gap between the spacer and the spacer is the yarn groove, and the yarn passes through different yarn grooves to form a weft knitted fabric. Although this structure is relatively fast, due...

Problems solved by technology

[0003] In weft knitting, the most commonly used weaving element is the needle cylinder. The conventional needle cylinder is composed of an upper needle cylinder and a lower needle cylinder. The gap between the spacer and the spacer is the yarn groove, and the yarn passes through different yarn grooves to form a weft knitted fabric. Although this structure is relatively fast, due to the limitations of the needle cylinder itself, the yarn The thickness of the thread and the pattern of the weave can only be circulated along the weft direction. Although some people in the industry have developed irregular needle cylinder micro-units such as those provided by patent 2013207319358 to achieve the adjustment of different needle level widths, but the large circular knitting machine with this structure There are still certain defects in the needle cylinder. In the weaving process, the upper needle cylinder adopts a conventional structure, and the lower needle cylinder adopts the irregular needle cylinder micro-unit as described in this patent. During the weaving process, the pattern, yarn count The change of thickness can only be realized by the lower needle cylinder, which is very prone to wrong stitches, and this irregular structure is easy to cause the yarn to be loose and tight at times, and in serious cases, there may even be thread jumping, which is not conducive to production control

[0004] At the same time, the thickness and style of the front and back of the fabric produced by the traditional ordinary double-sided large circular machine are not much different; in the current clothing market, thick needle clothing is very popular, but most of them are single-sided thick needle, double-sided thick Knitted fabrics are generally thick and not suitable for making spring and autumn clothing
