Embodiment 1

[0019] Put the cloth in warm water at 50°C, and use the bleaching liquid to boil for 50 minutes at a temperature of 100°C, the bath ratio is 1:10, and the vehicle speed is 90m / min. In this embodiment, the bleaching liquid Concentrations are: 1g / L cooking agent, 2g / L 100% hydrogen peroxide, 1g / L disodium edetate, 2g / L lipid polyammonium salt, 1g / L anti-wrinkle agent, 2g / L sodium hydroxide, and then washed in warm water at 50°C until the bleaching solution is neutral.

Embodiment 2

[0021] Put the cloth in warm water at 60°C, and use the bleaching liquid to boil for 60 minutes at a temperature of 95°C, the bath ratio is 1:15, and the vehicle speed is 100m / min. In this embodiment, the bleaching liquid Concentrations are: 2g / L cooking agent, 4g / L 100% hydrogen peroxide, 0.5g / L disodium edetate, 1g / L lipid polyammonium salt, 1.5g / L anti-wrinkle agent, 3g / L sodium hydroxide, and then washed in warm water at 60°C until the bleaching solution is neutral.

Embodiment 3

[0023] Put the cloth in warm water at 55°C, and use the bleaching liquid to boil for 55 minutes at a temperature of 98°C, the bath ratio is 1:12, and the vehicle speed is 95m / min. In this embodiment, the bleaching liquid includes Concentrations are: 1.5g / L cooking agent, 3g / L 100% hydrogen peroxide, 0.6g / L disodium edetate, 2g / L lipid polyammonium salt, 1g / L anti-wrinkle agent , 2g / L sodium hydroxide, and then washed in warm water at 55°C until the bleaching solution is neutral.

[0024] The whiteness of the bamboo-cotton blended fabric after boiling and bleaching in Examples 1-3 has all increased by more than 12.7%, greatly reducing the strong damage of the fiber, and the dyeing is uniform, the capillary effect level, the color fastness of the dye are high, and there is no staining, Good appearance.

Abstract

The invention discloses scouring and bleaching liquid for bamboo and cotton blended fabric. The scouring and bleaching liquid is prepared by scouring agents, 100% hydrogen peroxide, stabilizers, softening agents, anti-wrinkle agents and sodium hydroxide, wherein the concentration of the scouring agents is 1-2 g / L, the concentration of the 100% hydrogen peroxide is 2-4 g / L, the concentration of the stabilizers is 0.5-1 g / L, the concentration of the softening agents is 1-2 g / L, the concentration of the anti-wrinkle agents is 1-1.5 g / L, and the concentration of the sodium hydroxide is 2-3 g / L. The invention further discloses a scouring and bleaching method using the scouring and bleaching liquid. Through improving an existing scouring and bleaching method and the formula of the scouring and bleaching liquid, the whiteness and capillary effect of fibers used for blending are greatly improved, the strength damage of the fibers is reduced, the finally-produced fabric is flat in surface, even in color and luster, high in dye color fastness, free of staining and excellent in appearance, and all the properties are capable of meeting requirements.

Description

technical field [0001] The invention relates to a bleaching solution and a bleaching method for bamboo-cotton blended fabrics, belonging to the technical field of fabric printing and dyeing. Background technique [0002] For bamboo fiber, due to the presence of natural pigments, after blending with cotton fiber, the whiteness and capillary effect will be greatly changed. And if the boiling and bleaching effect is not good, the uniformity of the whiteness of the fabric surface will be poor, and the strength of the fabric will decline, which will seriously affect the quality of the fabric after the bamboo-cotton blend. Contents of the invention [0003] In order to overcome the problems of the prior art, the purpose of the present invention is to provide a kind of bleaching solution and a method for bleaching bamboo-cotton blended fabrics which have good bleaching effect and can effectively improve the whiteness and quality of the fabric. [0004] In order to solve the prob...
