Embodiment 1

[0028] The fabric in this embodiment is a cotton-wool blended fabric, specifically: 70N / 1 mercerized shrink-proof wool 18.5M50 / long-staple cotton 50 blended yarn cotton wool fabric, the wool and cotton content each account for 50%, and the weight is 5kg.

[0029] The hydrogen peroxide alkaline activator used in the embodiment is Dinglaocavi BAC purchased from Huntsman Chemical Co., Ltd., USA.

[0030] In the jet dyeing machine, the processing of cotton and wool blended fabrics includes the following steps:

[0031] (1) Degreasing of wool components

[0032] Inject industrial soft water into the jet dyeing machine at a liquor ratio of 1:12, put the fabric into the jet dyeing machine, and heat up to 60°C for 10 minutes. After watering again, add penetrating agent DepicolJT (Germany Sima Chemical Co., Ltd.) 1g / L, heat up to 70°C, keep warm for 20 minutes, and drain. Feed water, heat up to 60°C and wash with water for 10 minutes, then drain.

[0033] (2) Bleaching of cotton and...

Abstract

The invention relates to a method for processing white cotton and wool blended fabric. The method mainly comprises deoiling of wool components, bleaching of cotton and wool components and whitening of the cotton and wool components. According to the method, in the bleaching procedure, proper bleaching temperature and time are selected, related addition agents are preferably selected, processing of the cotton and wool components is balanced, the cotton components can obtain satisfactory whiteness, and the wool components cannot be damaged too seriously.

Description

technical field [0001] The invention belongs to the field of processing methods of blended fabrics, in particular to a processing method of white cotton wool blended fabrics. Background technique [0002] The processing of white cotton-wool blend fabrics consists of two main parts - bleaching and brightening of the fabric. Among them, the bleaching process of fabrics must be carefully considered: [0003] (1) temperature [0004] The oxygen bleaching temperature of cotton is generally above 90°C, too low temperature will affect the bleaching effect of hydrogen peroxide and affect the whiteness of cotton. And considering that wool will be damaged under high temperature and alkaline conditions, the oxygen bleaching temperature of wool should not be too high. [0005] (2) Hydrogen peroxide alkaline catalyst [0006] Considering the limited tolerance of wool to high temperature and alkalinity, the selected catalyst should have a high catalytic decomposition effect of hydroge...
