Method for producing elastic jacquard spacer fabric by a double-needle-bar warp knitting machine

Abstract

The invention discloses a method for producing elastic jacquard spacer fabric by a double-needle-bar warp knitting machine. The method includes that a spacing yarn guide bar and a jacquard guide bar are arranged in the middle; ground bars are arranged on the outer sides of the spacing yarn guide bar and the jacquard guide bar; elastic guide bars are arranged on the outer sides of the ground bars; according to different purposes of the to-be-produced spacer fabric, the distance between warp knitting machine needle bars is configured correspondingly; yarns include spacing yarns, jacquard yarns, surface yarns and elastic yarns, and according to difference of surface structures of the spacer fabric, the surface yarns and the elastic yarns with corresponding linear density are selected; the jacquard surface is designed through CAD (computer-added design) software; the surface yarns and the elastic yarns are matched to be knitted into the upper surface layer and the lower surface layer of the spacer fabric, the jacquard yarns are knitted on the surface of the spacer fabric to form single-color or double-color jacquard effect according to design in the step (4), and the spacing yarns are knitted into a middle spacer layer of the spacer fabric. The elastic jacquard spacer fabric produced by the method is good in elasticity and has single-color or double-color jacquard effect.

Description

Technical field: [0001] The invention belongs to the field of textile textiles, in particular to a method for producing elastic jacquard spacer fabrics on a double-needle bed warp knitting machine. Background technique: [0002] The warp-knitted jacquard spacer fabric not only has excellent compression resistance, breathability, moisture absorption, moisture conduction, sound insulation, shock absorption, heat conduction and other characteristics, but also the new jacquard technology not only beautifies the appearance of the product but also enriches the product variety. Therefore, many shoe materials are currently used , Clothing, seats, and bags are all made of warp-knitted jacquard spacer fabrics. [0003] The imported models for producing warp-knitted jacquard spacer fabrics include RDPJ4 / 1, RDPJ5 / 1, RDPJ7 / 1, and the domestic models include GE2296, ZMY7 / 1, etc. These models are equipped with 1 jacquard bar, 1~2 spacer yarn guide bars, and the others are ordinary bars. ...

AI Technical Summary

Problems solved by technology

Since the double-needle bed jacquard machines are not equipped with elastic bars, the warp-knitted jacquard spacer fabrics produced by these machines have insufficient elasticity, small deformation capacity, and uncompact structure, which affects comfort and aesthetics during use.

Moreover, because it is technically difficult to manufacture high-gauge double-bar warp knitting machines, the style of jacquard spacer fabrics woven by existing double-needle bar warp knitting machines is rough, and it is difficult to produce denser spacer fabrics.

[0004] The warp knitting machines for warp knitting jacquard spacer fabrics at home and abroad are all equipped with one jacquard bar, which makes it difficult to produce two-color (or multi-color) jacquard spacer fabrics. Restricted, insufficient aesthetics, and the variety of spacer fabrics produced is not rich enough

[0005] In summary, the currently used warp-knitted spacer fabrics do not integrate aesthetics, elasticity, comfort, and variety, and cannot meet people's needs.
