Problems solved by technology

However, the key point is that the darkening performance of all darkening agents on textiles has a great relationship with the refractive index of the darkening agent. These developed darkening agents often have high refractive index, so although they have better performance, But the deepening effect still needs to be further improved
In addition, many darkening agents also have problems in actual use. For example, the widely used silicone oil darkening agent often has oil floating phenomenon in actual use, which affects the quality of finished textiles.

Abstract

The invention discloses a cation-type quaternization organic fluorosilicon oil darkening finishing agent, and a preparation method and application thereof. The preparation method comprises the following steps: performing ring-opening reaction to polymerize octamethylcyclotetrasiloxane, 1,3,5-trimethyltris-1,5-(3,3-trifluoropropyl)-cyclotrisiloxane, N-(beta-aminoethyl)-gamma-aminopropyl methyldimethoxysilane, water and an end-capping reagent which are raw materials under the action of a strong-alkaline catalyst, so as to obtain amino-hydrocarbon modified organic fluorosilicon oil; performing reaction on N, N-dimethyl alkylamine and epoxy chloropropane to obtain glycidyl alkyl dimethyl ammonia chloride; adding an organic solvent, in which the glycidyl alkyl dimethyl ammonia chloride is dissolved, into the amino-hydrocarbon modified organic fluorosilicon oil for reaction, so as to obtain quaternized organic fluorosilicon oil; finally emulsifying the quaternized organic fluorosilicon oil in water. The method disclosed by the invention is environment-friendly and pollution-free; the obtained cation-type quaternization organic fluorosilicon oil emulsion is obvious in darkening effect on textiles, is particularly suitable for darkening dark polyester fabric and can well keep the style and the handfeel of the textiles.

Description

technical field [0001] The invention relates to a textile finishing agent and a preparation method thereof, in particular to an organic fluorosilicone oil darkening finishing agent and a preparation method thereof, which is applied in the technical field of dark-colored polyester fabric darkening treatment. Background technique [0002] On the premise of not increasing the amount of dye, the color of the fabric can be deepened, not only to obtain dark fabric, but also to save dye, reduce production costs, and reduce the content of colored substances in printing and dyeing wastewater. For this reason, scientific and technological workers at home and abroad have done a lot of research work and achieved certain results. [0003] At present, the methods of fabric deepening can be classified into three categories: [0004] (1) Physical and / or chemical treatment of fibers to roughen the surface of the textile, reduce the surface reflection of light, increase the absorption of dye...
