Production method of two-needle bed baseless jacquard sandwich fabric

Abstract

The invention relates to a production method of a two-needle bed baseless jacquard sandwich fabric. The production method is characterized by comprising the following steps that 1, a pattern of the baseless jacquard sandwich fabric is determined; 2, guide bars of a two-needle bed single jacquard warp knitting machine sequentially comprise two half-gauge front needle bed jacquard guide bars, an interval yarn guide bar and two back needle bed ground guide bars; the front needle bed jacquard guide bars penetrate into jacquard yarn, the interval yarn guide bar penetrates into interval yarn, and the back needle bed ground guide bars penetrate into back needle bed ground yarn; 3, in the weaving process, the two jacquard guide bars conduct symmetrical reversed yarn laying to form a jacquard surface fabric, the back needle bed ground guide bars conduct yarn laying and looping on back needle bed to form a base layer fabric, yarn laying and looping are conducted on the interval yarn alternatively on the front needle bed and the back needle bed to connect the jacquard surface fabric with the base layer fabric, and the baseless jacquard sandwich fabric is obtained. According to the production method of the two-needle bed baseless jacquard sandwich fabric, the baseless jacquard sandwich fabric which is rich in pattern, light, thin and good in stability can be obtained.

Description

technical field [0001] The invention relates to a production method of a jacquard interval forming fabric, in particular to a production method of a double-needle bed bottomless jacquard sandwich fabric, and belongs to the technical field of fabric weaving. Background technique [0002] Warp-knitted jacquard sandwich fabric has excellent compression resistance, breathability and moisture permeability, warmth retention, softness and other characteristics, and it can be formed at one time, with high production efficiency. In addition, the surface of this kind of fabric has rich pattern effect and good decoration, so it has been widely used It is used in the production of fabrics such as shoe materials, bags, seats, sofas, etc. [0003] When producing traditional warp-knitted jacquard sandwich fabrics, the jacquard surface is woven together by jacquard combs and floor combs, of which the jacquard combs are two and a half machine gauge configured with the same direction of the y...

AI Technical Summary

Problems solved by technology

[0003] When producing traditional warp-knitted jacquard sandwich fabrics, the jacquard surface is woven together by jacquard combs and floor combs, of which the jacquard combs are two and a half machine gauge configured with the same direction of the yarn lapping bar, and the same direction of the jacquard comb During the jacquard process, the jacquard comb forms a thick, thin, and mesh jacquard effect through the offset of the jacquard needles. A single jacquard comb cannot ensure that each needle can be lapped and looped, so it cannot independently form a piece of fabric and needs to be reconfigured. A ground comb together forms a jacquard surface, so the jacquard surface is relatively thick and does not feel light and thin
