Problems solved by technology

However, the currently used decolorization method only emphasizes the achievement of satisfactory whiteness. The actual production shows that the acquisition of whiteness is at the cost of damaging the fiber, and the loss of fiber strength has a great impact on the production rate and high count yarn in the subsequent production and processing. Spinnability has a huge impact, so the current decolorization process either has insufficient whiteness or a large loss of strength, which is not conducive to subsequent production and processing

Abstract

The invention discloses a process for discoloring camel hair fibers. The process comprises the following specific steps: pretreatment, oxidation treatment and reduction treatment. According to the mode, the process for discoloring camel hair fibers provided by the invention has the advantages that whiteness needed by dyeing can be met, strength needed for producing spun high-count-density yarns during post-production is achieved, and a test of discolored camel hair shows that the whiteness value of the camel hair fibers is improved by 296%, and the post- production dyeing requirements can be met. Meanwhile, the strength loss is only 6.5%, and smooth operation of post-combing slivering and high-count-density spinning can be ensured.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a decolorization process of camel hair fibers. Background technique [0002] Camel hair is a precious natural textile raw material among colored fibers. It has sufficient elasticity, is not easy to feel and shrink, has a smooth surface, and its wearing performance is close to that of cashmere. However, because the camel hair itself has a darker brownish yellow color, it affects the diversity development of its flower and color varieties. A small amount has been used for woolen processing, and the product has a single color; most of them are used as filling materials for clothing and quilts, with low added value, resulting in a huge waste of high-grade raw materials. Therefore, it is of great significance to re-dye the camel hair after decolorization to produce new camel hair products with excellent wearing performance, noble quality and rich colors, so as to meet the needs of consumers a...
