Abstract

The invention discloses a dyeing method for an anti-cutting fabric. The dyeing method comprises the following steps: pre-treating a gray fabric; firstly drying; performing corona treatment; scraping and impressing pigment printing paste; secondarily drying; baking; acquiring the end product. According to the invention, an ultra-high molecular weight polyethylene fabric is subjected to corona treatment so as to generate low temperature plasmas; under the effect of the low temperature plasmas, free radical reaction happens on the surface of the ultra-high molecular weight polyethylene fabric, the polymer is cross-linked, the surface is roughened and the wettability to polar solvents is promoted; the plasmas enter into the surface of the ultra-high molecular weight polyethylene fabric in themanner of electric shock and permeation to damage the molecular structure of the ultra-high molecular weight polyethylene fabric and oxidize and polarize the molecules on the treated surface. According to the invention, ion electric shock is utilized to erode an inert surface of the ultra-high molecular weight polyethylene fabric, so that the adhesive ability of the surface of the ultra-high molecular weight polyethylene fabric is promoted, the adsorptive property of the coating is enhanced, the color depth is increased, the pigment consumption for same color depth is reduced, the cost is lowered and the pigment dyeing is clean and environment-friendly.

Description

technical field [0001] The invention belongs to the field of fabrics in the textile industry, and in particular relates to a dyeing method for cut-resistant fabrics. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber is a high-performance fiber that was industrialized in the 1980s, also known as high-strength and high-modulus polyethylene (PE) fiber. The performance characteristics of UHMWPE fiber, such as high relative molecular mass, high orientation, highly entangled molecular chains and high crystallinity, endow the material with excellent comprehensive performance, with low density, high modulus, UV resistance, wear resistance, impact resistance, High strength and other properties, it has the best cost performance among the three existing fiber materials. Ultra-high molecular weight polyethylene (UHMWPE) fibers, UHMWPE fibers have extremely high crystallinity, lack of dyeing groups, and are difficult to dye, while ultra-high molecular ...
