Abstract

The invention relates to a preparation method of an efficient emulsifying dispersion degreaser, which comprises the following steps: adding butyl oleate sodium sulfonate, alkyl polyoxyethylene derivative, polyoxyethylene-polyoxypropylene block copolymer, polyacrylamide and dioctyl sebacate into a flask provided with a stirrer, a thermometer and a reflux condensing tube; adding deionized water and fatty alcohol sulfate monoethanolamine salt; heating to 90 DEG C; feeding nitrogen for protection; stirring for 35-55min; then slowly dropwise adding sodium chlorite for about 2h; insulating for 2h, and then adding tannin, ethanol and lauryl alcohol polyoxyethylene ether phosphate; reacting for 6-9h; and cooling to room temperature to obtain the emulsifying dispersion degreaser. The emulsifying dispersion degreaser has very strong degreasing emulsification and anti-after-tack functions and is used for decontaminating and degreasing environment-friendly textiles during dyeing.

Description

technical field [0001] The invention relates to a textile auxiliary agent, in particular to a preparation method of a high-efficiency emulsifying, dispersing and degreasing agent. Background technique [0002] In the printing and dyeing industry, knitted fabrics such as polyester, polyester-cotton and polyester-spandex are mostly knitted by cylindrical machines. In recent years, in order to weave fabrics more quickly and reduce costs, most of the manufacturers will greatly increase the use of oils and inferior oils, which will undoubtedly bring great difficulties to the printing and dyeing process. Dyeing houses often encounter the problem of inexhaustible stains, spots and oil spots. If secondary processing is adopted, that is, first scouring and degreasing under alkaline conditions, and then dyeing and processing, the advantages of doing so are clean degreasing and less disease protection, but the disadvantages are large energy consumption, long process time and high cost...
