Problems solved by technology

Although the silk floss quilt prepared by the traditional processing method is very good in wearing performance, after long-term use, the silk and cotton fibers tend to stick together and become entangled, and then the elasticity, softness, and warmth retention of the silk floss will decrease, and it needs to be turned over after a period of time. Only by loosening the silk floss can the silk floss fibers be fluffy and dispersed, and the characteristics of softness, comfort and warmth can be restored, which brings inconvenience to the user
Furthermore, in the process of preparing silk floss, due to improper processing technology, the silk floss fibers are entangled and bonded after degumming, which leads to the decrease of the elastic bulkiness and thermal performance of the prepared silk floss, which greatly reduces the use value of the silk floss.

Abstract

The invention belongs to the technical field of mulberry silk processing, and particularly relates to a method for preparing elastic expanding silk floss by mulberry silk by-products. The method includes the steps: (1) adding the mulberry silk by-products, water and immobilization strains into a rot cylinder to ferment mixture, regularly leading in a magnetic field in the fermentation process, andfiltering and dewatering the fermented mulberry silk by-products; (2) taking hydrogen peroxide, percarbamide and basic ionic liquid to add water to prepare water solution, adjusting a pH (potential of hydrogen) valve of the water solution, placing the fermented mulberry silk by-products into the water solution according to the bath ratio of 1:(20-30), soaking the mulberry silk by-products, and heating the mulberry silk by-products to remove glue; (3) adding hydrogen peroxide, EDTA (ethylene diamine tetraacetic acid) and oxalic acid into water to obtain mixed solution, and placing the mulberrysilk by-products after glue removal into the mixed solution to soak and bleach the mulberry silk by-products; (4) flushing the bleached mulberry silk by-products by clear water to obtain coarse silkfloss, and treating the coarse silk floss by the aid of expanding agents and finishing agents to obtain the elastic expanding silk floss.

Description

technical field [0001] The invention belongs to the technical field of silk processing, in particular to a method for preparing elastic bulky silk floss by utilizing 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 mat...
