Problems solved by technology

[0006] The purpose of the present invention is to provide a method for preparing regenerated fiber fabrics in order to overcome the deficiencies of the prior art. The preparation method is simple and easy, and can realize the recycling and reuse of waste polyester fabrics in a high-speed, fast and efficient manner, turning waste into treasure , not only effectively solve the environmental problems caused by the refractory degradation of waste polyester fabrics, but also save energy, achieve a virtuous cycle of the two systems of ecology and economy and unify the three major benefits of economy, ecology and society, and are suitable for continuous large-scale production; preparation The obtained regenerated fiber fabric has good comprehensive performance, good performance stability, moisture absorption and breathability, and easy dyeing

preparation example Construction

[0015] The preparation method of the regenerated fiber fabric of the present invention, the regenerated fiber fabric includes top thread texture and bottom thread texture, wherein: the mass percentage of the bottom thread texture in the fabric is 20-40%, and the rest is top thread texture; The surface silk structure is formed by surface silk, and the bottom thread structure is formed by bottom thread; the bottom thread raw material is 75D / 36F regenerated semi-gloss FDY as the bottom thread raw material, and the surface thread raw material is modified regenerated DTY; it includes the following Steps: Step (1) Raw material warping: Warp the regenerated semi-gloss FDY and modified regenerated DTY through the warping machine; because the hardness of the regenerated fiber raw material silk is relatively high, the resistance of the tensioner is set to 6 during the warping process. Ensure the flatness of the yarn during the warping process; store the warped head for 24h-30h and then t...

Embodiment 1

[0019]This example provides a kind of regenerated fiber fabric, comprises top thread structure and bottom thread structure, wherein: the mass percentage that described bottom thread structure accounts for in the fabric is 20%, and the rest is top thread structure; The bottom thread structure is formed by bottom thread; the bottom thread raw material is 75D / 36F regenerated semi-gloss FDY as the bottom thread raw material, and the top thread raw material is modified regenerated DTY; the fineness of the modified regenerated DTY is 120D .

[0020] The preparation method of the modified regenerated DTY comprises the steps of:

[0021] S1, crushing waste polyester fabrics to obtain waste polyester fragments;

[0022] S2. Modified allyl 3-O-benzyl-2- Add O-chloroacetyl-alpha-L-rhamnopyranoside and azobisisobutyronitrile into N,N-dimethylformamide, stir and react at 70°C for 3-5 hours under nitrogen atmosphere, and then The solvent was removed by rotary evaporation to obtain a copo...

Embodiment 2

[0033] Example 2 provides a regenerated fiber fabric, its formula and preparation method are basically the same as in Example 1, the difference is that the fineness of the modified regenerated DTY is 150D; the weaving process is specifically: L1 process, 4444 0000 33330000 ; L2 process, 0110; L3 process, 0101.

Abstract

The present invention relates to a preparation method of a regenerated fiber fabric. The method comprises the following steps of (1) raw material warping, wherein regenerated semi-dull FDYs and modified regenerated DTYs are warped by a warping machine, because regenerated fiber raw material yarns have the relatively high hardness, the resistance of a tension device is set to be 6 in the warping process to ensure the flatness of the yarns in the warping process, and the warped raw materials are store for 24-30 h and then are conveyed to a weaving workshop for use; (2) weaving and slitting, wherein the warped raw materials in the step (1) are woven by a warp knitting machine in proportion to obtain a gray fabric, and slitting is performed to obtain a slit gray fabric; and (3) after-finishing, wherein the prepared gray fabric in the step (2) is subjected to white body carding, ironing and pre-setting process treatment, and then dyeing, softening, fabric arranging, plush hot air treatment,napping, carding, ironing and shearing are performed to prepare the finished fabric. The preparation method is simple and feasible, recycling of waste polyester fabrics can be realized in a high-speed, quick an efficient manner, and wastes are turned into wealth.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a preparation method of regenerated fiber fabrics. Background technique [0002] With the development of science and technology and the improvement of living standards, people's desire to improve the living environment is becoming more and more urgent, and their understanding of environmental issues and energy issues is getting deeper and deeper. How to protect the environment in the rapid economic development is our key One of the most difficult tasks faced. The earth's stunning environmental protection development, each of us should have a sense that we should maintain a simple life, reduce the demand on the earth, reduce the burden on the earth, and minimize carbon emissions, so try not to waste in life and work, there are alternatives Use alternative energy whenever possible. [0003] Recycled chemical fibers use waste chemical fibers or textiles and other waste pol...
