Abstract

The invention discloses an epoxy-based organic fluorosilicone oil emulsion darkening finishing agent, made from, by weight, 5-35% of octamethylcyclotetrasiloxane, 0.5-10% of 1,3,5-tris(3,3,3-trifluoropropyl)methylcyclotrisiloxane, 0.1-6% of 3-[(2,3)-epoxypropyl]propylmethyldimethoxysilane, 0.001-0.1% of a terminator, 0.001-0.1% of a high-alkality catalyst, 0.1-2% of an emulsifier, and the balance of deionized water; the epoxy-based organic fluorosilicone oil emulsion darkening finishing agent has a following structural formula, wherein X equals to 10-100, Y equals to 80-1000, Z equals to 8-80, and all X, Y and Z are integers; a preparation method of the darkening finishing agent is simple, the reaction process is easy to perform, an obtained emulsion is stable, the darkening finishing agent has significant darkening effect when applied to darkening post-finishing of dark fabric, and washing fastness and handle of textile fabrics can be improved.

Description

technical field [0001] The invention relates to an epoxy-based organic fluorine silicone oil emulsion darkening finishing agent and a preparation method thereof, belonging to the technical field of textile dyeing and finishing auxiliaries. Background technique [0002] A kind of man-made fiber is widely used. It is made of natural cellulose through alkalization to form alkali cellulose, and then reacts with carbon disulfide to form cellulose xanthate. The viscous solution obtained by dissolving in dilute lye is called viscose, viscose After wet spinning and a series of treatment processes, it becomes viscose fiber. The chemical composition of viscose fiber is similar to that of cotton. It has a large number of hydroxyl groups on the surface and has good hygroscopicity. Blended with other textile fibers, the fabric is soft, smooth, Good breathability. Artificial viscose fibers are generally dyed with reactive dyes. Due to its typical "skin-core" structure, a large amount of ...
