Novel textile dyeing technology

Abstract

The invention relates to a novel textile dyeing technology. The technology includes performing unwinding on grey cloth on an unwinding machine; performing stitching on the unwound grey cloth; sendingthe grey cloth into dye vats to perform dyeing, adding 1-2 parts by weight of glycerol, 8-9 parts by weight of ethanol, 2-3 parts by weight of coconut oil fatty acid diethanolamide, 4-5 parts by weight of polyvinylpyrrolidone, 6-7 parts by weight of a natural plant pigment, 1-2 parts by weight of hydroxypropyl methyl cellulose, 2-3 parts by weight of imidazoline and 30-35 parts by weight of waterinto the dye vats before dying, and uniformly stirring the mixture, the soaking time of the grey cloth in the dye vats being 40 min; performing dehydration on the dyed cloth, putting the cloth in a pretreatment solution to perform reaction for 10 min, performing dehydration again, and widening and shaping the cloth on a scutching machine; performing printing through a calico printing machine; andperforming yardstick through a yardstick machine, and performing packing into finished products. The advantages of the technology are that the technology is simple in operation and environmentally friendly, sewage discharging can be reduced, and the protection on environments can be realized.

Description

technical field [0001] The invention belongs to the field of textile processing, in particular to a novel textile dyeing process. Background technique [0002] At present, the printing and dyeing of cotton cloth mainly consists of dyeing, printing, finishing, washing and other processes. It is a relatively mature process. The cotton cloth printed and dyed through the above process has rich colors and high color fastness. After printing and dyeing, the cotton cloth can still maintain good softness. However, after printing and dyeing cotton cloth, waste gas and waste water are generally produced, polluting the environment. In order to solve this problem, people have invented processes and equipment for treating waste gas and waste water, but this requires a lot of manpower and material resources. It also has the above-mentioned characteristics of cotton cloth after printing and dyeing. However, due to the chemical composition and technical reasons of the dyes and auxiliaries ...

Problems solved by technology

[0002] At present, the printing and dyeing of cotton cloth mainly consists of dyeing, printing, finishing, washing and other processes. It is a relatively mature process. The cotton cloth printed and dyed through the above process has rich colors and high color fastness. After printing and dyeing, the cotton cloth can still maintain good softness. , but after cotton cloth is printed and dyed, waste gas and waste water are generally produced, polluting the environment

In order to solve this problem, people have invented processes and equipment for treating waste gas and waste water, but this requires a lot of manpower and material resources. It also has the above-mentioned characteristics of cotton cloth after printing and dyeing. However, due to the chemical composition and technical reasons of the dyes and auxiliaries in the traditional printing process, it is very difficult to control the standard discharge of the printing process and complete clean production. It is difficult to chemically react with general ink and chemical coatings, so ink printing has not been possible

[0003] The prior art has disclosed a kind of waterless printing environmental protection ink and the use method of the ink. The ink can produce chemical reaction with cotton cloth, replace printing and dyeing with printing, and can achieve the color fastness, gloss and softness of the printing and dyeing process, but In actual operation, it is found that its color fastness is generally only 3-4, and its softness is not enough.
