Abstract

The invention discloses a deepening and brightening finishing agent for dyed cotton fabric and a preparation method thereof, which are characterized in that the preparation method comprises the stepsof: (1) synthesizing organosiloxane polymers modified by functional groups, to be specific, subjecting a certain amount of silicone monomers to certain conditions with coupling agents, such as tetramethyltetraphenylcyclotetrasiloxane and gamma-piperazinylpropylmethyldimethoxysilane to obtain organosiloxane polymers modified by functional groups; (2) emulsifying the organosiloxane polymers modifiedby functional groups in a high-speed shearing emulsifying machine to obtain organosiloxane polymer emulsions modified by functional groups and having milky white and slightly blue light; and (3) adding additives, hydroxyl silicone oil emulsion and polyoxyethylene wax emulsion into the organosiloxane polymer emulsions modified by functional groups to finally obtain a finished deepening and brightening finishing agent. The deepening and brightening finishing agent is an organosilicon finishing agent which provides deepening by reducing the refractive index of the surface of fabric, the color and luster of the fabric finished by means of the organosilicon finishing agent are deepened, dyes are saved, and the cost is reduced. In addition, fabric is soft and smooth to touch, is glossy and hashigh market value.

Description

technical field [0001] The invention relates to a finishing agent for textiles, in particular to a finishing agent for darkening and brightening dyed cotton fabrics and a preparation method thereof. Background technique [0002] Printing and dyeing is an industry with high pollution and high energy consumption, and the cost of sewage treatment and energy consumption is relatively high. In recent years, with the continuous development of textile technology, people have higher and higher requirements for clothing fabrics. One of them is the evaluation of the first sensory evaluation of textiles, that is, the evaluation of color. People hope that the color of colored fabrics will be more vivid and bright. , the color tone is more high-end, especially customers have higher and higher requirements for dark fabrics (especially reactive black and sulfur black). high demands. [0003] At present, the methods of fabric darkening treatment mainly include: cationic modification of th...
