Abstract

The invention relates to a preparation method for environmentally-friendly plant type cotton fiber fixing agent, and belongs to the technical field of textile materials. Apple slags are decomposed andextracted, and pectin is collected as the basic material of the material; through hydroxy, amido or a small quantity of carboxyl rich in pectin materials, active groups are in the presence on the surface of a cotton fiber to be subjected to crosslinking to form a film; meanwhile, the pectin material, dyes and groups on the fiber are subjected to crosslinking combination, the pectin material, thedye and the group on the fiber also can form a hydrogen bond to be bound with force among modules; in addition, through lycopodium spore powder, ball milling is carried out, certain condensation is generated through the carboxyl and the hydroxy contained in the ball milling of the lycopodium spore powder, a reticular macromolecule is formed under a certain condition, so that dye is adhered to fabric, meanwhile, cutinase can be used for effectively modifying the surface structure of cotton fibers, the binding strength of the dye on the surface of the cotton fibers is improved, and the color fastness of materials is effectively improved.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly plant-type cotton fiber color fixing agent, which belongs to the technical field of fabric materials. Background technique [0002] After the fibers and fabrics are dyed, although they can be dyed with brighter colors, some dyes have soluble groups that make the wet fastness poor, fading and staining not only make the appearance of the textile itself old, but also dyes Will come off dyed wet fibers to stain their fibers and fabrics. For example, direct dyes and acid dyes only rely on van der Waals force and hydrogen bonds to bond with fibers, and their wet rubbing fastness is low. In order to overcome these phenomena, color fixing treatment is usually required, and the reagent used is called color fixing agent. Fixing agents are often used in textile dyeing. For example, direct dyes, reactive dyes, and acid dyes all use color-fixing agents, and more are used when dyeing dark co...
