Abstract

The invention relates to the technical field of textile finishing agent, in particular to a fiber deep dyeing promoter. According to weight percentage, the fiber deep dyeing promoter comprises 10-30% of hydroxyl-terminated amino silicone oil, 1-10% of part hydrolysate of methyl trimethoxysilane, 3-20% of nonionic emulsifier, 0.5-5% of acetic acid, and 55-85% of deioned water; after textile finishing, the fiber deep dyeing promoter is attached to the surface of the fiber textile and generates moist crosslinking reaction during the heat treatment process so as to form a single-molecule organosilicon polysiloxane film layer; by virtue of the extremely low reflectivity of the rganosilicon polysiloxane film layer, the light radiating on the surface of the textile generates refraction and diffuse reflection on the fiber surface, the absorption quantity of the incident light of the textile is greatly increased and the reflective light is reduced, thus achieving the effect of deepening dyeing.

Description

Technical field: [0001] The invention relates to the technical field of textile finishing agents, in particular to a fiber dyeing deepening agent. Background technique: [0002] At present, because synthetic fibers have high strength, good wear resistance, and low cost, their output has increased year by year. In recent years, they have been widely used and accepted. Among them, polyester fiber has the largest output. As a high value-added product, textiles often require a high-end sense of deep color. For polyester fibers, it is difficult to achieve the desired color depth through dyeing methods. Polyester fiber has a special specular luster and a refractive index of 1.71. Therefore, when light is irradiated on the surface of the polyester fiber, a large amount of incident light is reflected on the surface of the fiber, and only a small part of the incident light is refracted to the inside of the fiber. The dye absorbs and becomes colored light, resulting in insufficient dyeing ...
