Abstract

The invention discloses a refining process for a tussah cut cocoon. The process is realized through the following steps of: pre-soaking, washing and dehydration, cocoon cooking, washing and dehydration, bleaching, washing and dehydration, softening, dehydration, drying, waste silk opening. The process provided by the invention solves the problems of difficult deoiling, excessive sericin shedding, crispy and breakable silk, undesirable silk floss bulking intensity and fibre breaking strength, low cleanliness and the like in traditional process technologies of tussah cut cocoon shells. According to the process, the product quality can reach and exceed the national industry standards, thereby improving the quality of tussah silk refined waste silk and tussah silk quilt products.

Description

technical field [0001] The invention relates to the technical field of textile engineering, in particular to a refining process for tussah silkworm cocoon cutting. Background technique [0002] With the rapid rise of the tussah silkworm pupae market and the deep development of the tussah silk quilt market, the production, processing and sales of tussah cocoons have undergone tremendous changes. Tussah silkworm cocoon shells, which were originally the main product, were mainly used for silk reeling and silk weaving. Now they have been transformed into cutting cocoons to eat pupae, cocoon shells to process silk floss, and silk floss to process silk quilts. cocoon shell) has become a by-product of tussah silkworm production. According to incomplete statistics, the country produces about 50,000 to 60,000 tons of tussah cocoons and 6,000 tons of cut tussah cocoons every year. Cut cocoon, improve its product quality and grade, will be the important bottleneck of whole tussah ind...
