Problems solved by technology

Silk reeling is one of the main processing raw materials for silk cotton. It is cheap and has all the advantages of high-quality cotton. At present, enterprises mainly use the soap-alkali method to degumming and degreasing it. This method has the disadvantages of large amount of alkali consumption, long processing time, and Incomplete removal, strong odor, easy to produce precipitation, and relatively large damage to silk floss. In addition, unreasonable processing methods can easily lead to hardening and shrinkage of silk floss during use, which seriously affects the hygroscopicity and air permeability of silk floss. properties such as sex and warmth retention, greatly reducing the application value of silk cotton

Abstract

The invention belongs to the technical field of silk processing, and particularly discloses a method for preparing silk floss from mulberry silk byproducts. The method includes steps of (1), adding water and mulberry silk byproducts, water and immobilized strains into decaying vats, carrying out fermentation, then taking out the mulberry silk byproducts, and filtering and dehydrating the mulberrysilk byproducts to obtain fermented mulberry silk byproducts; (2), adding 30% hydrogen peroxide w / w, amide percarbonate and alkaline ionic liquid into water to prepare aqueous solution, regulating a pH (potential of hydrogen) value of the aqueous solution, placing the fermented mulberry silk byproducts in mixed solution A according to a bath ratio of 1:20-30, soaking the fermented mulberry silk byproducts in the mixed solution A at the normal temperature at first, then heating the fermented mulberry silk byproducts and degumming the fermented mulberry silk byproducts; (3), adding 30% hydrogenperoxide w / w, EDTA (ethylene diamine tetraacetic acid) and oxalic acid into water to obtain mixed solution B, then placing degummed mulberry silk byproducts in the mixed solution and carrying out soaking bleaching treatment on the degummed mulberry silk byproducts; (4), washing the mulberry silk byproducts by clear water after bleaching treatment is carried out on the mulberry silk byproducts, drying and dehydrating the mulberry silk byproducts and acquiring the silk floss after the silk floss is qualified by detection.

Description

technical field [0001] The invention belongs to the technical field of silk processing, and in particular relates to a method for preparing silk floss from mulberry silk by-products. Background technique [0002] With the development of the economy, the silkworm planting industry continues to develop, and the increase in silkworm production has also brought good benefits to local silkworm farmers. But in the past, the production of sericulture products is still limited to the sales of silkworm cocoons at a lower level, and the utilization of other by-products of sericulture is not high, so that the benefits of sericulture by-products have not been brought into full play. If the by-products of sericulture are developed, it can not only rationalize and maximize the development and utilization of local sericulture resources, but also increase farmers' income. [0003] The main components of wastewater from silk reeling factories are high-molecular protein organic matter such a...
