Problems solved by technology

However, when the darkening agent is applied to the darkening of superfine fibers after dyeing with paint, since the adhesive has formed a film on the surface of the fiber, the darkening effect of the darkening agent is not obvious, and an additional layer of thickening is added. The deep treatment process increases the cost of dyeing, which is not conducive to industrial promotion
[0005] The invention patent CN103774460A authorized by China discloses a method of improving the color depth of dyeing by placing cationic modified cotton fiber aggregates in a dye liquor mixed with alcohol organic solvents, water and paint for pad dyeing. The addition of alcoholic organic solvents in this method will easily make the compatibility between the various additives in the dyeing liquor worse, the particle size of the pigment will increase, and the color fastness after dyeing will decrease.
The invention patents CN103556497A and CN102182007A authorized by China respectively disclose the method of using small molecular dyes and coatings to compound dyeing to increase the color depth, but the application of disperse dyes increases the energy consumption of dyeing, while the application of indigo and sulfur dyes reduces the color depth.

Abstract

The invention discloses pigment dyeing liquor for dyeing superfine fibers and a method for improving dyeing color depth of the superfine fibers, belonging to the technical field of textile science. According to the invention, an acrylic macromolecular dye is added into the pigment dyeing liquor comprising a water-based pigment paste, an adhesive, a penetrant and other components, the uptake rate of the dye in the superfine fibers is enhanced by virtue of the characteristic that salt bonds can be easily formed between the macromolecular dye and the fibers, and the color depth of the superfine fibers is improved while the excellent color fastness is guaranteed by virtue of the characteristic that a main chain structure of the macromolecular dye is similar to a structure of the adhesive. The technology has the characteristics of simple dyeing process, little pollution, stable product quality, high color depth and the like, and has good application prospects.

Description

technical field [0001] The invention relates to a coating dye solution for superfine fibers and a method for using the same, in particular to a coating dye for superfine fiber dyeing and a method for improving the color depth of superfine fiber dyeing, belonging to the field of textile science and technology. Background technique [0002] Superfine fiber is named after the ultra-fine linear density or fineness of the fiber. It is a typical representative of the new synthetic fiber that chemical fiber is developing towards high technology and high simulation. It has soft hand feeling, soft luster, good drapability and breathability. It is widely used in synthetic leather, imitation silk fabrics, medium and high-end clothing fabrics, medical protective fabrics, paper products and other fields. It can effectively improve the grade and added value of products, and has a good development prospect. [0003] At present, there are two main methods of dyeing microfibers, namely, dye ...
