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.
