Abstract

The invention relates to a method of pigment dyeing after modifying a ramie fiber fabric. The method comprises the following steps: with ramie fibers as a raw material, carrying out modification by virtue of N-methylol acrylamide, 3-chloro-2-hydroxypropyl trimethylamine hydrochloride and methacrylate, and further carrying out pigment dyeing by virtue of a dyeing solution formed by a D type dyeing pigment red, an adhesive, a migration inhibitor, a crosslinking agent, silicone oil and MgCl2. The method has the advantages that the dyeability of the ramie fibers is improved, and the elongation, the loop strength, the softness, the fatigue property and the dyeing property of the ramie fibers are greatly improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to the fabric modification and dyeing process. Background technique [0002] As the oldest textile fiber, hemp fiber is considered to be a witness of human history. The hemp fiber covered by hemp textile includes: flax, ramie, jute, sisal, kenaf, hemp, apocynum and so on. Strong hygroscopicity, fast heat dissipation, strong anti-corrosion and anti-bacterial ability, soft color, recyclable, ecological and environmental protection... Many advantages make hemp products exist and develop in human life from ancient times to the present, and the development of hemp spinning products It is also a manifestation of the development of human wisdom. [0003] Due to the high crystallinity, high degree of orientation, small inclination angle and closely arranged aggregate structure, hemp fiber has the defects of poor dyeability, which is manifested in the slow diffusion of dyes into the fiber...
