Problems solved by technology

However, the use of low bath ratio equipment brings quality problems such as scratches, chicken paw prints, and aurora prints to the dyeing of high-count and high-density fabrics, which are more likely to occur than those dyed by overflow machines.
Moreover, with the change of people's consumption concept, fabrics such as high-count and high-density mercerized fabrics, tencel fabrics, cupro fabrics, and memory fabrics are becoming more and more popular. The fibers of these fabrics tend to swell in a wet state. The friction force increases, and it is easy to cause the above-mentioned dyeing quality problems.

Abstract

The invention relates to the field of textile auxiliaries, in particular to a preparation method of a textile dyeing synergist. The synergist is prepared by synthesizing polysiloxane with side chainscontaining hydrogen, allylpolyethyleneglycol (APEG, Mn=1,300), 3-[(2,3)-epoxy propoxy]propyl methyl dimethoxy silane and N,N,N,N-tetramethyl hexamethylene diamine. The allylpolyethyleneglycol and theN,N,N,N-tetramethyl hexamethylene diamine are adopted as a hydrophilic monomer as an organosilicone chain segment for graft modification, the prepared synergist is applied to cellulosic fiber and polyester fiber textile dyeing, friction between fibers can be lowered, and scratching and streak flaws of a fabric in the wet processing process are reduced.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a preparation method of a fabric dyeing synergist. Background technique [0002] At present, in order to cope with the pressure of energy saving, emission reduction and rising production costs, the use of low liquor ratio printing and dyeing equipment has been basically popularized. However, the use of low liquor ratio equipment brings quality problems such as scratches, chicken paw prints, and aurora prints to the dyeing of high-count and high-density fabrics, which are more likely to occur than those dyed by overflow machines. Moreover, with the change of people's consumption concept, fabrics such as high-count and high-density mercerized fabrics, tencel fabrics, cupro fabrics, and memory fabrics are becoming more and more popular. The fibers of these fabrics tend to swell in a wet state. The increase of friction force is easy to cause the above-mentioned dyeing quality prob...
