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.

Embodiment 1

[0010] A method for preparing a super-stretched double networked silk fabric, comprising three process steps of elastic double networked yarn manufacturing, knitting and weaving, and dyeing and finishing, and is characterized in that:

[0011] 1. The manufacturing process of stretched double network yarn: the raw material is a homogeneous mixture of high crystalline polymer of ethylene terephthalate copolyester and high crystalline polymer of polytrimethylene terephthalate, using sulfamic acid Combination of two substances with alumina as a catalyst, the above mixture is first formed into a prepolymer, and then the prepolymer is subjected to a polycondensation reaction under high temperature and vacuum conditions to form a low-viscosity polymer, which is fed into a screw extruder, where the screw The heating temperature from the feed section to the discharge section of the extruder is in the low temperature range of 100-160°C, and the heating temperature from the feed section t...

Abstract

The invention relates to a preparation method of ultra-strong elasticized dual-network winding silk fabric, which comprises three process steps, namely manufacturing of elasticized dual-network winding silk, knitting and weaving, and dyeing and finishing, and the ultra-strong elasticized dual-network winding silk fabric which has excellent fluffy, soft, smooth, straight, plump and skinny style in comparison with acrylic fiber plush fabric by improving and optimizing related processes and parameters in the steps.

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 ...
