Embodiment 1

[0028] The present embodiment provides a cotton-wool blended fabric and its smooth and soft process, which comprises the following steps:

[0029] S1. Put the cotton-wool blended fabric in an environment with a temperature of 50°C and an ultrasonic power of 250W for 0.5h;

[0030] S2. Dry the cotton-wool blended fabric after ultrasonication in step S1 to a constant weight at 80°C, and soak the dried cotton-wool blended fabric in a polyacrylate emulsion with a concentration of 4o.w.f% at a bath ratio of 1:20; and Add acetic acid to the polyacrylate emulsion to adjust the pH value to 6.0; then add JFC penetrant with a concentration of 4g / L and stir, smooth and soften the cotton-wool blended fabric at 35°C for 1h, and finally dry it at 85°C for 5min, and then Dried to constant weight at 105°C to obtain a smooth and soft cotton-wool blended fabric.

Embodiment 2

[0032] The present embodiment provides a cotton-wool blended fabric and its smooth and soft process, which comprises the following steps:

[0033] S1. Put the cotton-wool blended fabric in an environment with a temperature of 65°C and an ultrasonic power of 200W for 0.5h;

[0034] S2. Dry the cotton-wool blended fabric after ultrasonication in step S1 to a constant weight at 100°C, and immerse the dried cotton-wool blended fabric in a polyacrylate emulsion with a concentration of 7o.w.f% at a bath ratio of 1:30; and Add acetic acid to the polyacrylate emulsion to adjust the pH value to 4.0; then add JFC penetrant with a concentration of 5g / L and stir, smooth and soften the cotton-wool blended fabric at 45°C for 0.75h, and finally dry at 95°C for 5min. Then dry to constant weight at 106° C. to obtain a smooth and soft cotton-wool blended fabric.

Embodiment 3

[0036] The present embodiment provides a cotton-wool blended fabric and its smooth and soft process, which comprises the following steps:

[0037] S1. Put the cotton-wool blended fabric in an environment with a temperature of 58°C and an ultrasonic power of 225W for 0.5h;

[0038] S2. Dry the cotton-wool blended fabric after ultrasonication in step S1 to a constant weight at 90°C, and soak the dried cotton-wool blended fabric in a polyacrylate emulsion with a concentration of 5.5o.w.f% at a bath ratio of 1:25; and Add acetic acid to the polyacrylate emulsion to adjust the pH value to 5.0; then add JFC penetrant with a concentration of 6g / L and stir, smooth and soften the cotton-wool blended fabric at 40°C for 0.85h, and finally dry at 90°C for 5min, and then Dry to constant weight at 104°C to obtain a smooth and soft cotton-wool blended fabric.

Abstract

The invention discloses a smoothening and softening process for a cotton and wool mixture. The smoothening and softening process comprises the following steps: S1, ultrasonically treating the cotton and wool mixture in an environment with the temperature of 50-65 DEG C; and S2, soaking the ultrasonically processed cotton and wool mixture in the step S1 in a mixed solution of polyacrylate emulsion and a penetrating agent to perform smoothening and softening finishing. Scales on the surfaces of wool fibers fall off through ultrasonic treatment, so that the softness of the wool fibers is improved and the polyacrylate emulsion and the penetrating agent can conveniently enter the wool fibers to improve the softness of the wool fibers; meanwhile, the ultrasonic treatment also can ensure that irregularly distributed holes are formed in the surface of the cotton and wool mixture, so that the degree of bonding between the cotton and wool mixture and each of the polyacrylate emulsion and the penetrating agent is improved and the softness and washing fastness of the cotton and wool mixture are enhanced; and the obtained cotton and wool mixture has the characteristics of high washing fastness, good smoothness and softness, attractiveness and high comfort.

Description

technical field [0001] The invention belongs to the technical field of cotton-wool blended fabrics, and in particular relates to a smoothing and softening process of cotton-wool blended fabrics. Background technique [0002] Wool fiber is favored by consumers for its excellent comfort and good dyeing performance, but due to its high production cost, wool fiber is often blended with other textile fibers. Because cotton fiber also has good moisture absorption and sweat-conducting properties and a relatively complete color spectrum, it becomes a more suitable fiber material for blending with wool fiber. Cotton-wool blended fabrics feel hard after repeated processing, and the smoothness decreases, which affects the beauty and comfort of the fabric. However, the cotton-wool blended fabrics after smoothing and softening have greatly improved the defects of cotton-wool fabrics and improved the quality of the fabrics. Take performance. [0003] At present, most of the smooth finis...
