High-quality mulberry silk manufacturing technology

Abstract

The invention discloses a high-quality mulberry silk manufacturing technology. The technology includes the specific steps of cocoon stripping, cocoon assorting, vacuum steaming, ultrasonic cooperative cocoon cooking, silk reeling, re-reeling, post-processing, testing, packaging, storage and the like. By means of the technology, cleanliness of silk is improved, and silk reeling quality is comprehensively improved, so that under the action of ultrasonic waves, the inside and the outside of a cocoon shell achieve the effects that sericin is uniformly swovlen, shell dropping on the inner layer is reduced, the reelability rate is improved, steaming efficiency is improved, work energy consumption is lowered, neatness and cleanliness of raw silk are improved, and fineness continuous dynamic non-contact detection of the raw silk is achieved. Quality of the raw silk is improved, raw silk drying efficiency is improved, and work energy consumption of equipment is lowered.

Description

technical field [0001] The invention relates to a production process of high-grade mulberry silk, belonging to the technical field of mulberry silk processing. Background technique [0002] Mulberry silk has a wide range of uses. For example, in the textile field, the silk textiles made of mulberry silk are not only soft and close-fitting, warm and breathable, but also have various health care effects on the human body; the hygroscopicity of silk is 1.5 times that of pure cotton, and it can absorb sweat from the human body Moisture is conducive to maintaining the balance of skin moisture; for example, in the medical field, silk protein can be used in the preparation of hydroxyapatite / polymer composite materials for bone regeneration, such as bones and ligaments, artificial tendons, artificial blood vessels and artificial ligaments, and It can be used in drug controlled release materials, bionic materials, tissue engineering materials, etc.; also in the field of daily chemica...

AI Technical Summary

Problems solved by technology

At present, the cocoon cooking pretreatment technologies used by domestic and foreign enterprises to produce mulberry silk mainly include high-temperature touch steaming technology and vacuum touch steaming technology. The temperature of the silkworm cocoon in the lower part is relatively high, and the temperature of the cocoon in the lower part is low. The steaming of the cocoon is uneven, and the effect of adjusting the quality of the cocoon by touch steaming is not ideal. pressure treatment process, microwave cocoon cooking process and automatic silk reeling process without cocoon cooking, etc. However, the above-mentioned processes have shortcomings, and it is difficult to meet the increasing quality requirements of reeled silk and raw silk products. For example, the temperature difference infiltration process is prone to uneven cooking, As a result, there is a large difference in the adhesive force between the cocoons and silk can not be reeled normally; it is difficult to achieve a uniform degree of cooking when the cocoons are cooked by the vacuum infiltration treatment process, which is not conducive to the relaxation of the cocoons. Undesirable consequences such as increased threads, increased sagging, clean raw silk, and low clarity grades; the V-type pressure treatment process has too much pupal oil leaching, and may even boil the pupae; the microwave cocoon cooking process lacks the effect of external force (such as Vibration, impact of water medium, etc.), after the microwave effect disappears, the sericin layer will return to its original state and structure. It is not conducive to silk reeling; the content of silk sericin in the automatic silk reeling process without cooking cocoons increases, and the woven silk is refined and dyed, and the weight of the satin is seriously inconsistent with the design.
