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.
Invention patents CN 103556497A and CN102182007A authorized by China respectively disclose the method of using small molecular dyes and coatings to compound dyeing to improve color depth, but the application of disperse dyes increases the energy consumption of dyeing, while the application of indigo and sulfur dyes reduces Color fastness

Embodiment 1

[0039] (1) Padding paint dye solution: immerse the microfiber in the paint dye solution at a temperature of 40°C for 10 minutes, then pad the paint dye solution once on a paddle car, and control the excess rate of 50%. Among them, the paint dye solution contains the following components: color paste TSE R0772 is 10g / L, acrylic macromolecular dye A 1g / L, binder is 40g / L, penetrant is 0.5g / L; (2) pre-baking : Pre-bake at 60°C for 5 minutes; (3) Baking: bake at 120°C for 5 minutes.

Embodiment 2

[0041] (1) Padding paint dye solution: immerse the superfine fiber in the paint dye solution at a temperature of 60°C for 5 minutes, and then pad the paint dye solution twice on a paddle car to control the excess rate of 70%. Among them, the paint dye solution contains the following components: color paste TSE R0871 is 25g / L, acrylic macromolecular dye B 2.5g / L, binder is 100g / L, and penetrant is 1g / L; (2) pre-baking : Pre-bake for 4 minutes at a temperature of 70°C; (3) Baking: bake for 3 minutes at 140°C.

Embodiment 3

[0043] (1) Padding paint dye solution: immerse the superfine fiber in the paint dye solution with a temperature of 80°C for 2 minutes, then pad the paint dye solution 3 times on the paddle car, and control the excess rate of 80%. Among them, the paint dye solution contains the following components: color paste TSE R0873 is 50g / L, acrylic macromolecular dye C 5g / L, binder is 200g / L, and penetrant is 2g / L; (2) pre-baking: Pre-bake at 90°C for 3 minutes; (3) Baking: bake at 150°C for 2 minutes.

Abstract

The invention discloses a paint dye solution for dyeing superfine fibers and a method for improving the color depth of superfine fiber dyeing, belonging to the field of textile science and technology. In the present invention, acrylic macromolecular dyes are added to the paint dyeing liquid containing water-based pigment paste, adhesives, penetrating agents and other components, and the characteristics of easy formation of salt bonds between macromolecular dyes and fibers are used to improve the super The uptake of dyes in fine fibers, and the use of the similarity between the main chain structure of macromolecular dyes and the binder structure, ensures excellent color fastness while improving the color depth of ultrafine fibers. This technology has the characteristics of simple dyeing process, less pollution, stable product quality, high color depth, etc., and has a good application prospect.

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 ...
