Problems solved by technology

Octamethylcyclotetrasiloxane has a lower refractive index of 1.396
The lower the refractive index, the more obvious the deepening effect is, and the silicone has a better deepening effect, but the polarity of the silicone is weak, the surface tension is small, the surface energy is low, and it is smooth, although it has a good deepening effect. , but it is easy to cause fiber slippage and cracking, especially for the finishing of polyester fabrics, slipping and cracking are more obvious

Abstract

The invention discloses a dyeing fabric deepening finishing agent and a preparation method. The dyeing fabric deepening finishing agent is prepared in a mixed and matched manner from water-based close polyurethane resin and water-based acrylic resin, wherein the water-based close polyurethane resin is prepared by polypropylene oxide triol, N-methyl diethanol amine, hexamethylene diisocyanate, acetone, acetoxime, dimethyl sulfate, glacial acetic acid, sodium hydrogen sulfite, deionized water and dibutyltin dilaurate, and the water-based acrylic resin is prepared by methyl acrylate, acrylonitrile, dimethylaminoethyl methacrylate, trifluoroethyl methacrylate, hydroxyethyl acrylate, methacryloyloxyethyl trimethyl ammonium chloride, azobis isobutylamidine hydrochloride and deionized water. The dyeing fabric deepening finishing agent is resistant in cracking and slipping and good in fixation effect.

Description

technical field [0001] The invention relates to a darkening finishing agent for dyed cotton fabrics or dyed chemical fiber fabrics, which is a dyed fabric darkening finishing agent mixed with water-based sealing polyurethane resin and water-based acrylic resin. Background technique [0002] The darkening finishing agents of dyed fabrics are mostly organosilicon darkening finishing agents at present. [0003] CN101956324B "Deepening and Brightening Finishing Agent for Dyed Cotton Fabrics and Preparation Method", discloses a dyed cotton fabric darkening and brightening finish mixed with polyorganosiloxane emulsion and methyl hydrogen-containing silicone oil emulsion at 100:5-10 agent. [0004] "Printing and Dyeing Auxiliaries" magazine 01, 2004, Xie Hongde published "The preparation and application research of darkening agent", proposed that methyltrimethoxysilane and KH-560 in the presence of cationic / nonionic surfactant, through Emulsion polymerization to obtain a transluc...
