Fresh cocoon processing method for improving flexibility of silk quilt

Abstract

The invention discloses a fresh cocoon processing method for improving the flexibility of a silk quilt. The processing method comprises the following steps: screening high-quality fresh cocoons; soaking the fresh cocoons in a mixed solution of sodium chloride, sodium bicarbonate and a Gemini cation softener for 6-12 h, wherein the concentration of the mixed solution is 12.5-16.5%, and keeping the soaking temperature at 45-55 DEG C; taking the soaked fresh cocoons out of the mixed solution, cleaning the obtained cocoons for 3-5 times with clear water of 20-30 DEG C, and performing centrifugal treatment for 8-10 min at a rotary speed of 2200-2500 r / min; putting the obtained fresh cocoons after centrifugal treatment in a heat pump drying oven for dehumidifying and drying; and performing sorting. Fresh cocoons are taken as raw materials for preparing the silk quilt; multiple production processes, such as cocoon drying, cocoon storage and transportation, are reduced; the production cost is greatly reduced; and the production efficiency is improved. The flexibility of the followed silk quilt is raised. The processing method is simple and easy to operate, is saved in energy, and has bright application prospects.

Description

technical field [0001] The invention belongs to the technical field of silk quilt production, and relates to a method for processing silkworm cocoons, in particular to a method for processing fresh cocoons to improve the softness of silk quilts. Background technique [0002] With the improvement of people's living standards, people are more and more advocating returning to nature. The consumption of pure natural silk quilts has increased sharply, and the consumer market has expanded year by year. The preparation method of the existing silk cotton quilt mainly includes the following steps: (1) take the silkworm cocoon after drying the cocoon as raw material, blank it in the silk cotton machine, and spray it with an alkaline spray liquid (such as a solution containing sodium hydroxide). (2) Refining and degumming the above-mentioned silk floss sheets; (3) After washing, finishing, dehydration and drying, loosening by hand, and making silk floss quilts according to conventional...

Problems solved by technology

[0003] However, the above method has the following problems: (1) fresh cocoons need to be dried, which increases the production process and relatively increases the production cost; Denaturing, that is, turning into insoluble sericin, so lye is needed in the spraying and refining degumming process, which not only increases the difficulty of the process, but also reduces the flexibility of the silk quilt made from fresh cocoons

However, it has been found in practical applications that if the existing silk floss quilt preparation method is used to process fresh cocoons, the following problems will occur: in the process of processing fresh cocoons with silk floss machines, the silkworm chrysalis body will be crushed, so that the silk floss sheet is stained with silkworm chrysalis. smell, which affects the quality of the silk cotton quilt

Therefore, how to use fresh cocoons as raw materials to realize the large-scale production of silk cotton quilts has become a technical problem that the industry has been eager to solve but has never been successful.
