Cotton fiber cold-reactor auxiliary agent

Abstract

The invention discloses a cotton fiber cold-reactor auxiliary agent, which comprises a cold reactor agent A and a cold reactor agent B, wherein the cold reactor agent A comprises the following components: 100 parts of strong base, 40 to 80 parts of weak base slat, 20 to 50 parts of sodium silicate, 10 to 30 parts of phosphate, 10 to 20 parts of chelating agent and 10 to 30 parts of urea; and the cold reactor agent B comprises the following components: 100 parts of alkanol polyoxyethylene polyoxypropylene ether, 20 to 40 parts of magnesium sulfate, 20 to 50 parts of fatty alcohol ethoxylates and 10 to 30 parts of lower alcohols. The pretreatment of the cotton fiber can be completed at the atmospheric temperature without using high-temperature solution, so a great amount of resources such as the steam, the water, the electric power and the like can be saved, the sewage discharge can be reduced, and the production cost can be effectively reduced. The cotton fiber cold-reactor auxiliary agent belongs to a typical auxiliary agent for the energy-saving discharge-reduction process. The product has simple and reliable treatment process, is easy to obtain various raw materials, is free from the complicated regulation, and can be widely popularized to use.

Description

technical field [0001] The invention relates to an auxiliary agent for cold stacking of cotton fibers, in particular to an auxiliary agent for processing cotton fibers without heating. Background technique [0002] The processing of cotton fiber is roughly divided into pretreatment, dyeing and posttreatment. In the pre-treatment process, it is necessary to remove impurities such as pectin, lipids and waxes inherent in cotton fibers. At the same time, it is also necessary to remove the textile oil, size and other impurities attached to the fiber in the weaving process to make the cotton fiber more pure and to obtain high-quality products. [0003] At present, the general cotton fiber pretreatment method is the strong alkali high temperature oxidation method, which is to put the cotton fiber into the high temperature strong alkali oxidation solution for treatment. Under the action of hot lye and oxidant, the inherent impurities such as pectin and wax on the cotton fiber are ...

Problems solved by technology

Although this treatment method can remove the impurities on the cotton fiber well, it will also damage the cotton fiber at the same time, resulting in a decrease in the strength of the fiber and affecting the quality of the product.

This method needs to consume a large amount of steam, water, electricity and other resources, and the production cost is also high, which is not conducive to sustainable development

[0004] Chinese Patent Application No. 200310115482.7 discloses the use of enzymes and their auxiliaries to treat cotton fibers, but the enzymes have strict requirements on the reaction conditions and require precise control to achieve satisfactory results. At the same time, the enzyme preparation and purification processes lead to enzyme prices It is also relatively high, which is also not conducive to cost reduction, and it is difficult to promote in a large area
