Problems solved by technology

At present, the methods of fabric darkening treatment mainly include: cationic modification of the surface of the fabric to improve the dyeing rate and fixation rate of the dye on the fabric, so as to achieve the purpose of dyeing dark colors; Additives can also make the dyeing achieve the purpose of deepening, but it can not improve the fabric feel, and it needs to be softened and finished, which wastes energy and increases costs.

Abstract

The invention discloses a preparation method of smoothing, stiffening and color deepening silicone oil. The method comprises steps as follows: (1) synthesis of the smoothing, stiffening and color deepening silicone oil: the smoothing, stiffening and color deepening silicone oil is prepared from certain amounts of octamethylcyclotetrasiloxane, dodecyl methyldimethoxysilane and gamma-piperazinylpropylmethyldimethoxysilane under the catalysis of a certain quantity of catalysts at certain polymerization temperature for a certain time; (2) emulsification of the smoothing, stiffening and color deepening silicone oil: 10% of 2-phenoxyethanol as a special emulsifier is added to a silicone oil emulsifier to emulsify the smoothing, stiffening and color deepening silicone oil, and milky-white smoothing, stiffening and color deepening silicone oil emulsion which has the content of 40% and has slight blue light is obtained. The smoothing, stiffening and color deepening silicone oil emulsion realizes the color deepening effect by reducing the surface refractive index of fabric and is an organosilicon finishing agent, and the hand feel finishing and color deepening of the fabric are performed simultaneously, so that energy conservation, environmental protection, color deepening, dye saving and cost reduction are realized.

Description

technical field [0001] The invention relates to an auxiliary agent for dyeing and finishing of textiles, in particular to a method for preparing smooth and darkening silicone oil. Background technique [0002] The printing and dyeing industry is an industry with high pollution and high energy consumption. The cost of sewage treatment and energy consumption occupies a large proportion of the cost of dyeing and finishing processing. In recent years, with the continuous improvement of the country and society's environmental protection requirements, the cost of dyeing has continued to increase, and the pressure on printing and dyeing enterprises has also continued to increase. Customers have higher and higher requirements for dark fabrics (especially reactive black and sulfur black), which also put forward higher requirements for printing and dyeing enterprises. At present, the methods of fabric darkening treatment mainly include: cationic modification of the surface of the fab...
