Problems solved by technology

[0004] In the cationic treatment, some people use the traditional cationic modifier. The cationic modifier firstly treats the fabric, which can easily lead to excessive local concentration, which will lead to color spot defects when the paint is dyed later.

Abstract

The invention relates to a cationic binder emulsion for denim paint dyeing. The binder emulsion is generated after a reaction of soft monomers, hard monomers, cationic monomers, crosslinking monomers, a compound emulsifier and an initiator. During preparation, a mixture of all the monomers and an initiator water solution are added into the emulsifier and distilled water for a reaction, cooling and filtering are conducted, and the cationic binder is prepared. The cationic binder is used for the denim yarn / fabric paint dyeing process or the paint overdyeing process, and during use, it is not needed to pretreat yarn / fabric or paint.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to a polymer emulsion for paint dyeing, in particular to an adhesive for denim yarn / fabric paint dyeing. Background technique [0002] Traditional denim or classic denim refers to a thick-count twill fabric made of pure cotton yarn indigo dyed as warp yarn, natural yarn as weft yarn, and three upper and lower right twill weaves. The yarn count is generally about 16. Coarse count yarn, the cloth surface is thicker. And now denim fabrics are not only cotton fibers, natural fibers such as hemp, wool, silk, recycled fibers such as viscose, tencel, modal, and synthetic fibers such as polyester, nylon, acrylic, spandex, etc. have been widely used. Therefore, in the current dyeing of denim textiles, the paint dyeing process has wider adaptability, and is a clean production process that can truly achieve energy saving and emission reduction. [0003] Pigment dyeing is a ...
