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

Embodiment 1

[0031] A method for preparing a non-twisted textile, which comprises the following process steps, specifically:

[0032] a. Preparation of alkali-degraded slices: During the polymerization of polyester raw materials, 5-sodium sulfonate-polyethylene glycol isophthalate with a total weight of 5% of the polymer and isophthalic acid with a total weight of 5% of the polymer are added. Diformic acid, beat and stir while heating to 230°C; then move to the reactor and add polyethylene glycol with a total weight of 5% of the polymer to dilute and cool down to 210°C; continue to add molecular weight to the reactor Polyethylene glycol is 6000, and polyethylene glycol accounts for 5% of polymer gross weight, adds polyethylene glycol within 50 minutes and stirs simultaneously, is warming up to 230 ℃ under normal pressure and makes mixed material under vacuum state Polymerization, after polymerization, the alkali-degraded slices are cast, cooled, pelletized, dried, and screened sequentially...

Embodiment 2

[0039] A method for preparing hollow textiles, which includes the following process steps, specifically:

[0040] a. Preparation of alkali-degraded slices: During the polymerization of polyester raw materials, add 5-sodium sulfonate-polyethylene glycol isophthalate with a total weight of 4% of the polymer and isophthalic acid with a total weight of 3% of the polymer. Diformic acid, beat and stir while heating to 230°C; then move to the reactor and add polyethylene glycol with a total weight of 5% of the polymer to dilute and cool down to 210°C; continue to add molecular weight to the reactor Polyethylene glycol of 6000, polyethylene glycol accounts for 3% of polymer gross weight, adds polyethylene glycol within 50 minutes and stirs simultaneously, is heated up to 230 ℃ under normal pressure and makes the mixed material under vacuum state Polymerization, the alkali-degraded slices after polymerization are finally cast, cooled, pelletized, dried and screened in sequence, wherein...

Embodiment 3

[0052] The preparation method of hyperbranched textile, it comprises the following processing steps, specifically:

[0053] a. Preparation of alkali-degraded slices: During the polymerization of polyester raw materials, 5-sodium sulfonate-polyethylene glycol isophthalate with a total weight of 3% of the polymer and isophthalic acid with a total weight of 4% of the polymer were added. Diformic acid, beat and stir while heating to 230°C; then move to the reactor and add polyethylene glycol with a total weight of 3% of the polymer to dilute and cool down to 210°C; continue to add molecular weight to the reactor Polyethylene glycol of 6000, polyethylene glycol accounts for 2% of the total weight of the polymer, and the polyethylene glycol is added within 50 minutes while stirring, and the temperature is raised to 230 ° C under normal pressure and the mixture is kept under vacuum. Polymerization, after polymerization, the alkali-degraded slices are cast, cooled, pelletized, dried, ...

Abstract

The invention discloses a method for preparing untwisted, hollow, highly branched textiles and a method for recovering dissolved matter in an alkali solution. The method for preparing untwisted, hollow, highly branched textiles comprises the following steps: a. preparing alkali-degradable slices; b. Preparation of blended spinning melt; c. Spinning to prepare easily alkali-soluble degradable fibers, which include filaments, staple fibers, and fiber strips; d. Untwisted textiles, hollow textiles, and highly branched yarns Textiles or embroidery products; the preparation method of the untwisted, hollow and highly branched textiles can effectively prepare soft and light textiles. The method of recovering the solute in the alkali solution is as follows: the alkali solution is obtained after the degradation of the easily alkali-soluble degraded fiber, and after acid analysis, terephthalic acid is obtained, and the filtered waste water meets the discharge standard, and is introduced into the biochemical treatment system of the factory; The method for recovering dissolved matter in the alkali solution can recover the alkali solution after the easily alkali-soluble degradable fiber is dissolved, has good environmental protection effect and can achieve the purpose of circular economy.

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 ...
