Problems solved by technology

[0004] The disadvantages of paint dyeing are: first, it can only dye medium color, the color of the fabric is relatively dull, the fastness to rubbing and washing is low, and the hand feels rough, especially for medium and deep dyed products.
Second, the nature of the paint itself causes streaks and uneven dyeing of the dyed product, and the processing machine is seriously polluted and cannot be used for other processes
[0005] Adhesives generally used in the prior art are high molecular polymers, mostly acrylic polymers. During the application process, it is easy to cause problems of sticking rollers and cleanliness
Chitosan is used in the paint dyeing process of fabrics. After heat treatment, a very firm protective film is formed on the surface of the fibers, and the paint is wrapped in it, so that the fabrics are colored and have strong washability. Fastness and rubbing fastness are not ideal

Abstract

The invention discloses a chitosan pigment dyeing binding agent added with sodium thioglycollate. The pigment dyeing binding agent is obtained by mixing sodium thioglycollate and chitosan. A preparing method of the chitosan pigment dyeing binding agent added with sodium thioglycollate comprises the steps that a sodium thioglycollate aqueous solution is sprayed to the surface of chitosan, and then the mixture is put into an oven to be dried to the constant weight at a high temperature; after drying, the mixture is smashed and then subjected to ultrasonic action for 1-2 h. According to the chitosan pigment dyeing binding agent added with sodium thioglycollate and the preparing method of the chitosan pigment dyeing binding agent added with sodium thioglycollate, added sodium thioglycollate can replace urea and olyoxyethylene lauryl ether added in the chitosan pigment dyeing process, the adding amount of chitosan is reduced, the pigment dyeing cost is reduced, and the color fastness and hand feeling quality of dyed fabric can be improved; the preparing process is simple, the sodium thioglycollate aqueous solution is sprayed into chitosan, no chemical preparation needs to be added, no new equipment or process needs to be added, the preparing process is simple, environmentally friendly, efficient and free of pollution, process cost is reduced, and high economic benefits and market promotion value are achieved.

Description

Technical field: [0001] The invention relates to the technical field of textile auxiliaries, in particular to a chitosan paint dyeing adhesive added with sodium thioglycolate. Background technique: [0002] my country has become a big country in textile printing and dyeing. With the development of printing and dyeing technology, the current dyeing process has been developed to dyeing not only with dyes but also with paints. Pigment dyeing has the advantages of wide fiber adaptability, complete color spectrum, convenient color matching, small water consumption, energy saving and consumption reduction, etc., so it is widely respected in the dyeing and finishing industry. Unlike dyes, paints have no affinity with fiber fabrics, and adhesives are needed to fix the paints on the surface of the fabrics. Therefore, the preparation technology of adhesives is one of the key technologies for the development of paint dyeing. The synthesis process and new product development of adhesi...
