Problems solved by technology

However, the all-polyester microfiber fabric known as ordinary double-sided coral velvet that is currently seen is made of 150D / 288F or 75D / 144F or 100D / 144F DTY as the suede surface, so the weight is generally 280- 350g / m 2 Between 4-5.5mm, the pile height is about 4-5.5mm, which is restricted by the gram weight and pile height, so this kind of fabric shows the following two deficiencies, one is that the suede is thin, and it shows a thin flat effect when stretched; the other is After fluffing on the reverse side, obvious unevenness will be left on the surface (front side), resulting in poor three-dimensional effect, less plump down feathers, and weak hand feeling
This kind of fabric is not super elastic enough. At the same time, because it cannot form a double network of network yarn, it cannot show the fluffy, soft, smooth and scratchy, plump and skinny style compared with acrylic plush fabric.

Abstract

The invention relates to a preparation method of an ultrastrong texturizing double-network silk fabric, comprising the following three process flow steps: manufacturing texturizing double-network silk, knitting and dyeing. By the improvement and the optimization of the relevant technologies and parameters in the above steps, the obtained ultrastrong texturizing double-network silk fabric is puffier, softer, smoother, neater, plumper and skinnier compared with acrylic fibers fabrics.

Description

technical field [0001] The invention relates to a preparation method of a super-strength elastic double network silk fabric. Background technique [0002] The steps included in the preparation method of stretched double network silk fabric are well known in the industry by taking the processing of warp knitting machine as an example. The specific steps are: DTY silk material selection (raw material preparation), warping, weaving, slitting, dyeing Or printing, loose drying, color fixing, finishing, heat setting, back raising finishing, sewing, and finishing into fabrics. In view of the fact that all polyester (also known as pure polyester) microfiber has a texture like cotton wool, it is widely used to process clothing, toys, shoes, hats, composite floor mats, quilted mats, bedding, etc.; and in view of pure polyester Microfiber fabric has good warmth retention. Therefore, in recent years, it has gradually replaced cotton-type products and acrylic products in the series of ...
