Anti-bacterial and anti-wrinkling finishing method for cotton fabric

Abstract

The invention provides an anti-bacterial and anti-wrinkling finishing method for cotton fabric, comprising the following steps of: dissolving catalyst, and equimolar 2, 2, 6, 6-tetramethyl-4-pipradrol and butanetetracarboxylic acid in water, so that finishing bath foam can be formed; and soaking the cotton fabric in the finishing bath foam, treating the cotton fabric by the working procedures such as rolling and baking, soaping, washing by water, drying, halogenating and drying, wherein the catalyst is one of the sodium dihydrogen phosphate, disodium hydrogen phosphate, sodium polyphosphate and sodium hypophosphite, the halogenating treatment comprises the step of soaking the dried cotton fabric in active halogen-containing solution, and the drying temperature is 150-200DEG C. The cotton fabric which is finished by the method in an anti-bacterial and anti-wrinkling finishing way has the dual performances such as bacterial resistance and wrinkling resistance, is high in anti-bacterial efficiency, good in anti-wrinkling performance, and free from formaldehyde release.

Description

technical field [0001] The invention belongs to the technical field of textile production, and in particular relates to an antibacterial and anti-wrinkle finishing method for cotton fabrics. Background technique [0002] Cotton fabric is favored by people because of its softness, comfort, breathability, good hygroscopicity and other excellent wearing properties. However, cotton fabrics have poor resistance to microorganisms, and when worn, they will absorb the hot and humid medium emitted by the human body, providing a good environment for the reproduction of microorganisms, resulting in bad smell, even fading and discoloration of the fabric, and reduced mechanical strength; In addition, when the cotton fabric is subjected to external forces during wearing, the cellulose molecular chains or their basic structural units will undergo relative displacement, the original hydrogen bonds will be dismantled, and new hydrogen bonds will be formed. When the external force is eliminat...

Problems solved by technology

[0003] At present, the conventional N-methylol amide resin is usually used as the anti-wrinkle finishing agent in the prior art. Although the finishing agent has a good durable and anti-wrinkle effect, the fabrics treated by it suffer from serious loss of strength, yellowing and large amount of formaldehyde release. And other shortcomings, and in the process of storage and wearing, will continue to release formaldehyde harmful to human body, stimulate human skin and respiratory mucosa, and even cause cancer

With the improvement of living standards, people pay more attention to the functionality of clothing, and textiles that are only finished with a single antibacterial or anti-wrinkle function no longer have a competitive advantage

Patent 200510123828 discloses an anti-wrinkle finishing method for colored cotton fabrics, using N-methylolamide resin as an anti-wrinkle finishing agent; although patent 200610119085 and patent 200810184879 use polycarboxylic acid formaldehyde-free finishing agents, they are limited to a single anti-wrinkle finishing; patent 00117001 discloses a production method for antibacterial and anti-wrinkle fabrics, but the fabrics treated by this method will release free formaldehyde; Shandong Textile Science and Technology Issue 5, 2001, pages 7 to 9 disclose A polycarboxylic acid (citric acid and tartaric acid) and chitosan for anti-wrinkle and antibacterial finishing of cotton fabrics, but treating cotton fabrics with chitosan as an antibacterial agent will affect the fabric style and make the fabric surface feel rough, and the The patent has not published its antibacterial performance test effect data
