Embodiment 1

[0016] The deepening treatment process of embodiment 1 black wool fabric comprises the following steps:

[0017] S1: Configure the first darkening finishing solution and the second darkening finishing solution. The main components of the first darkening finishing solution are fluorine-containing resin, penetrating agent and crosslinking agent, and the main components of the second darkening finishing solution are water-based polyurethane Resin, penetrating agent and cross-linking agent, the cross-linking agent in the first darkening finishing liquid and the second darkening finishing liquid are all cross-linking agents with blocked isocyanate groups, the first darkening finishing liquid and the second darkening finishing liquid The resin content in the deep finishing solution is 5g / L;

[0018] S2: First place the black wool fabric in the first darkening finishing solution, heat the reaction system to 50°C, soak for 20 minutes, then take out the squeeze solution until the liqui...

Embodiment 2

[0023] The difference between embodiment 2 and embodiment 1 is:

[0024] The resin content in the first darkening finishing liquid and the second darkening finishing liquid is 10g / L;

[0025] S2: First place the black wool fabric in the first darkening finishing solution, heat the reaction system to 30°C, soak for 50 minutes, then take out the squeeze liquid until the liquid retention rate is 60%, and pre-dry the fabric in an environment of 130°C until Dry, then immerse the fabric in the second darkening finishing solution, heat the reaction system to 50°C, immerse for 50 minutes, then take out the squeezed liquid until the liquid-carrying rate is 60%, and place the fabric in an environment of 130°C for pre-drying until dry. Then place it in an environment of 150° C. and bake for 3 minutes.

[0026] The bath ratio of the fabric in the first darkening finishing solution and the second darkening finishing solution is both 1:25.

[0027] The penetrating agent in the first darke...

Embodiment 3

[0030] The difference between embodiment 3 and embodiment 2 is that

[0031] The resin content in the first darkening finishing liquid and the second darkening finishing liquid is 7g / L;

[0032] S2: First place the black wool fabric in the first darkening finishing solution, heat the reaction system to 40°C, soak for 35 minutes, then take out the squeezing liquid until the liquid retention rate is 65%, and pre-dry the fabric in an environment of 120°C until Dry, then immerse the fabric in the second darkening finishing solution, heat the reaction system to 55°C, immerse for 40 minutes, then take out the squeeze liquid until the liquid-carrying rate is 65%, and place the fabric in an environment of 120°C for pre-drying until dry. Then place it in an environment of 155° C. and bake for 2 minutes.

[0033] The bath ratio of the fabric in the first darkening finishing solution and the second darkening finishing solution is both 1:30.

Abstract

The invention discloses a color-increased treatment technology for black wool fabric. The technology comprises two steps of preparing first color-increased finishing liquid and second color-increasedfinishing liquid, and performing color-increased treatment. The color-increased treatment technology for the black wool fabric adopts padding finishing of fluorine-containing resin and polyurethane resin with two low refractive indexes. A penetrant is helpful to the resin to be rapidly adhered on the surface of wool fibers even between wool scales, and a cross-linking agent is helpful to increasean adhesive force of the resin and the wool fibers, water washing resistance and friction and peeling resistance of a resin layer are improved.

Description

technical field [0001] The invention relates to the technical field of wool color deepening, in particular to a black wool fabric darkening treatment process. Background technique [0002] Full-wool thick black fabric requires pure black fabric color, lively hand feeling, clear surface, and excellent elasticity. As customers have higher and higher requirements for color depth, the darkening treatment of black worsted fabrics has become a research and development in this field in recent years. One of the hot spots. The black silk color deepening method of wool fabric mainly focuses on the dyeing step. Including increasing the concentration of black dye in the dyeing liquor, destroying the wool scale layer to increase the dyeing rate, cationic modification of the wool fiber before dyeing to increase the adsorption capacity between the dye and the wool fiber, adding level dyeing to the dyeing liquor to increase the depth agent and / or dyeing accelerator, ultrasonic dyeing, etc...
