Machine-made silk wadding quilt and preparation method thereof

Abstract

The invention discloses a preparation method of a machine-made silk wadding quilt. The preparation method comprises the following steps: (a) taking a fresh cocoon as a raw material, processing and separating the fresh cocoon by a cocoon cutting machine to obtain a fresh cocoon shell and a fresh silkworm pupa; (b) placing the fresh cocoon shell into hot water for dissolving, then conveying into a silk wadding machine and preparing into a silk wadding piece; (c) refining and degumming the silk wadding piece, wherein the refining and degumming operation is a high-temperature and high-pressure degumming operation, the pressure is 0.15-0.3MPa, the temperature is 120-140 DEG C, the degumming time is 1.5-2h, and water is taken as a solvent; and (d) washing, after-finishing, dehydrating and drying, manually garneting and preparing into the silk wadding quilt by a conventional method. According to the preparation method, the fresh cocoon is taken as the raw material for preparing the silk wadding quilt, so that multiple production steps of cocoon drying, storing, transporting and the like are reduced, the processing cost is greatly lowered, the production efficiency is improved, and the technical difficult problem which is eager to be solved for a long time in the industry but can not be solved all the time is solved.

Description

technical field [0001] The invention relates to a preparation method of machine-made silk cotton quilt. 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. [0003] The existing preparation method of silk floss quilt mainly includes the following steps: (1) take the silkworm cocoon after cocoon drying as raw material, put it into the silk floss 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, loosen them by hand, and make silk floss quilts according to conventional methods. [0004] However, the above method has the following problems: (1) fresh cocoons need to be dried, which increases the production p...

Problems solved by technology

[0004] 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; Denaturation, that is, turning into refractory sericin, so lye is needed in the process of spraying and refining degumming, which not only increases the difficulty of the process, but also inevitably causes environmental pollution

[0006] 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 and the silk floss sheet will be 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.
