Compound forming method of multi-layered knitted fabric made of multi-component raw materials

Abstract

The invention discloses a compound forming method of a multi-layered knitted fabric made of multi-component raw materials, wherein multiple raw materials are adopted to knit on a two-layered weft-knitting circular knitting machine, by changing the arrangement method of upper disc knitting needles and lower drum needles, the triangles knitted by the upper disc and the triangles knitted by the lower drum are arranged to form different upper and lower structures, and the upper and the lower layers can be compounded through the tucking knitting of the upper and the lower knitting needles. By adopting the same or different raw materials and the knitting method, the upper and the lower layers, namely front and back sides of the fabric and the lining materials are compounded, as a result, the fabric has the advantages that the production procedure is simple, no chemical component exists within, the elasticity is excellent, and the fill power is very high; furthermore, the two layers of the compound fabric can adopt different raw materials and different structures, so as to form different appearances and possess different styles and functions.

Description

technical field [0001] The invention relates to a composite molding method of multi-layer knitted fabric, in particular to a composite molding method of multi-layer knitted fabric of multi-component raw materials directly composited in the weaving process. [0002] Background technique [0003] Multi-layer knitted fabrics must be compounded in a certain way before they can be used, that is, fabrics of different layers need to be organized together in a certain way to form a whole. Traditional multi-layer knitted fabric composites are usually formed by chemical auxiliary bonding or second superimposed mechanical stitching. [0004] The process of bonding with chemical additives is: using chemical adhesives and hot pressing at high temperatures. The disadvantage is that: the chemical adhesives used will release harmful, harmful Formaldehyde and benzene pollute the environment; at the same time, the bonded parts will separate and fall off after the fabric is used for a period...

Problems solved by technology

[0004] The process of bonding with chemical additives is: using chemical adhesives and hot pressing at high temperatures. The disadvantage is that: the chemical adhesives used will release harmful, harmful Formaldehyde and benzene pollute the environment; at the same time, the bonded parts will separate and fall off after the fabric is used for a period of time, and the compounding effect is poor; at the same time, the bonded and compounded fabric lacks elasticity, which affects the soft feel and scope of use of the fabric

[0005] The second superimposed mechanical stitching process is: use mechanical stitching equipment to superimpose and stitch multi-layer fabrics and inner linings. The disadvantages are: the fabric has no elasticity, poor bulkiness, and poor wearing comfort; and the process is increased. increased production costs
