Problems solved by technology

[0006] At the same time, the above-mentioned alkali-soluble fiber patent does not involve the environmental protection and recycling of COD after dissolution
In fact, after the strong alkali dissolves the fiber, there will be a high content of non-biochemical substances, high cod, great environmental pollution, and unproductive
Dissolved substances are discharged with wastewater, causing huge waste

Abstract

The invention discloses a preparing method of non-twist textiles or hollow textiles or highly-branched textiles and methods for recycling solute of alkali solutions. The preparing method of the non-twist textiles or the hollow textiles or the highly-branched textiles includes the following steps of a, preparing alkaline degradation sections; b, preparing blended spinning melt; c, carrying out spinning to prepare alkali-easily-dissolved degradation fibers, wherein the alkali-easily-dissolved degradation fibers include filaments, short fibers and fiber strips; d, preparing the non-twist textiles or the hollow textiles or the yarn-highly-branched textiles or embroider products. The soft and light textiles can be effectively prepared with the preparing method of the non-twist textiles or the hollow textiles or the highly-branched textiles. The methods for recycling the solute of the alkali solutions include the steps that the alkali solutions are obtained after the alkali-easily-dissolved degradation fibers are degraded, terephthalic acid is obtained after acid separation, and filtered wastewater meets a draining standard and is led into a factory biochemical treatment system. By means of the methods for recycling the solute of the alkali solutions, the alkali solutions obtained after the alkali-easily-dissolved degradation fibers are dissolved can be recycled, the environment-friendly effect is good, and the aim of circular economy can be achieved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for preparing untwisted, hollow and highly branched textiles and a method for recovering dissolved matter from an alkali solution. Background technique [0002] In the process of textile processing, the application of degradable fibers includes the following types, specifically: 1. Blending degradable (soluble) fibers with other fibers into yarn and weaving, and then degrading the degradable fibers to obtain high-count Yarn; 2. Blend fibers that cannot be spun and weaved with such degradable fibers or weave them together, so that fibers that cannot be spun and weaved can also be woven; 3. As a base fabric for embroidery , show flowers on the degradable fiber cloth, and finally degrade the degradable fiber to get a complete flower pattern; 4. For untwisted terry yarn, such as combining cotton yarn with water-soluble PVA and twisting the direction, and then weaving into ...
