Abstract

The invention relates to a method for transforming and recycling old cotton. The method comprises the following steps of: after soaking the old cotton in an acid soak solution prepared from acid complex enzyme, a surfactant and inorganic acid, rinsing the old cotton; then soaking the old cotton in an alkaline soak solution prepared from alkaline complex enzyme, the surfactant and caustic soda; and finally, carrying out rinsing and cooking, cleaning, chlorination blenching, dechlorination, acid washing and drying. Compared with a chemical degumming treatment method, a biological degumming method adopted by the invention has the advantage of saving water by 30 percent, so that the consumption of the water resources is reduced; the acid content and the alkali content of discharged waste water are greatly reduced, so that the environment pollution is low and the treatment cost is reduced at the same time; compared with cotton processed with the chemical degumming method, the cotton processed with the method disclosed by the invention has the advantages of good fibers, strong elasticity, high fiber index, few impurities, few white points, good softness and color, high whiteness and the like.

Description

(1) Technical field

[0001] The invention relates to a method for transforming and recycling old cotton. (2) Background technology

[0002] At present, chemical degumming is usually used for the recycling of old cotton. This treatment method consumes a lot of water, has a high treatment cost, and has a high acid-base content in the discharged wastewater, which causes great environmental pollution. The quality of the cotton obtained by the treatment is not high, such as low fiber index, poor elasticity, many impurities, and many white spots. (3) Contents of the invention

[0003] The purpose of the present invention is to provide a method for renovating and reusing old cotton with low processing cost, little environmental pollution, and good quality of the treated cotton.

[0004] The present invention is realized in this way:

[0005] The method includes the following steps:

[0006] A. First, soak the old cotton in an acid soaking solution prepared from an acid compound...
