A manufacturing process for a structure that prevents down from shifting and maintains fabric elasticity

Abstract

The invention provides a structure that prevents down from shifting and maintains fabric elasticity and its manufacturing process, which includes two layers of fabric layers and down, and the down is filled between the two layers of fabric layers, and also includes a plurality of connection points, The connection points are used to position the down and make the down distributed in a net shape, the two fabric layers are all made of stretched and elastic fabrics, and the down is wrapped with an elastic breathable film. The technical solution provided by the invention enables the elastic down products to maintain the elasticity of the fabric to the greatest extent, and at the same time keeps the distribution of the down uniform, anti-drilling, and will not be displaced due to external forces such as gravity.

Description

technical field [0001] The invention relates to fabric fabrics, in particular to a structure for preventing down displacement, drilling down and maintaining fabric elasticity and a manufacturing process thereof. Background technique [0002] At present, there are many down products on the market, such as down jackets, bedding, etc. The structures of these down products are basically the same. , during use, down is easy to drill out from the pores of the lining and fabric. Therefore, down products have high requirements for the density of the lining and fabric; A coat with a certain degree of looseness, but it is not possible to make close-fitting and corseted down products. [0003] In the prior art, in order to prevent eiderdown products from drilling down, the fleece-proof fabric is used to solve the problem of down drilling of common fabrics and elastic fabric down products. But because the anti-velvet fabric itself does not have elasticity, the anti-velvet fabric will ...

AI Technical Summary

Problems solved by technology

But because the anti-velvet fabric itself does not have elasticity, the anti-velvet fabric will limit the elasticity of the elastic fabric down products. Restrictions, so that the elasticity of elastic fabrics is greatly restricted, such down products are still not suitable for close-fitting wear

At the same time, the down products in the prior art, in order to prevent the down from shifting due to gravity and other reasons, all use horizontal, vertical or grid-style open stitching. Although such a way can play a role in limiting the down displacement, but at the same time It also greatly limits the tension and elasticity of elastic fabrics, and the surface of down products that adopts horizontal, vertical or grid-style topstitching forms a very obvious convex and concave gully shape, which is not beautiful and has a single and dull shape.

[0004] Due to the above-mentioned reasons, there is no down product that has elastic function, prevents down from drilling out and shifting, and is suitable for wearing next to the skin.
