Problems solved by technology

[0003] For nylon thin and dense fabrics, due to its poor hygroscopicity, very fine fiber density in the fabric, and poor water absorption, the printing paste contains a large amount of paste during conventional printing. After printing, the color paste is attached to the surface of the fabric and is not easy to penetrate. Cause serious color build-up and staining when printing the second set of colors, let alone printing multiple sets of colors

Abstract

The invention provides acid dye foam printing liquid and method for a chinlon thin fabric. The acid dye foam printing liquid contains dyes, a foaming agent, a compound stabilizing agent and a thickening agent, wherein the dyes include three-primary colors including weak acid yellow GN, polar red B and weak acid brilliant blue Rawl; the foaming agent is lauryl sodium sulfate with high foaming amount and rich foams; and the compound stabilizing agent is n-dodecyl alcohol and CMC-Na; and the thickening agent is high-viscosity CMC-Na. According to the method, an acid dye foam dye bath is foamed by virtue of an Auto Foam dyeing machine and is applied to multicolor printing of the chinlon thin fabric. According to the acid dye foam printing liquid, the problem of serious staining of the chinlon thin fabric is solved; the liquid content is low, so that the fabric is very easy to dry after the printing, and the drying link is omitted; meanwhile, the consumption of a thickener is very low, so that the processing pressure after the water washing is greatly reduced; and the production cost is lowered, the production efficiency is improved, and the acid dye foam printing method is environmentally friendly.

Description

technical field [0001] The patent of the invention belongs to the technical field of textile printing and dyeing, and specifically relates to an acid dye foam printing solution and a foam printing method for nylon thin fabrics. Background technique [0002] Nylon acid dye printing products occupy an important position in synthetic fibers, and are mainly used in clothing linings, outdoor products, women's knitted underwear, etc. The demand is large, so its printing technology is also constantly developing. Acid dyes are the most widely used dyes in nylon dyeing, accounting for about 65% of the total nylon fiber dyes. The existing foam printing technology is a kind of three-dimensional printing of paint, which uses the mixture of foaming agent and adhesive to form foam and print on the fabric. During the baking process, the foam in the adhesive is less or not broken. Make the printed pattern on the fabric have the effect of three-dimensional protrusion; And the nylon thin fab...
