Description
Technical Field
The invention belongs to the technical field of silk processing, and particularly relates to a short-process raw silk preparation method by utilizing five-instar silkworms to directly spin and stretch and twist.
Background
The silk is an excellent natural protein fiber, is the only filament fiber in natural fiber cotton, hemp, silk and wool, has light and slender silk, good glossiness, comfortable wearing and smooth and plump hand feeling, and is usually used for weaving various silk fabrics for high-grade clothing. The silk is a natural high molecular biological material, has excellent mechanical property, controllable biodegradability and easy processability, and particularly has good biocompatibility, so that the silk becomes an ideal regenerative biological scaffold material. In recent years, research and application of silk have been extended from the traditional field to high and new technical fields, such as flexible wearable electronics, biomedical materials, and the like.
The traditional silk processing technology mainly comprises the following processes: mixing cocoons, peeling cocoons, selecting cocoons, boiling cocoons, reeling, soaking, re-shaking, knitting, packing, unpacking, soaking with an auxiliary agent, drying, rewinding and subsequently weaving. Because silk receives the long-time effect of chemicals in the cocoon cooking process and the effect of various chemical additives in subsequent processes, the silk structure can be damaged to a certain extent, and the mechanical property is worsened. Silk needs a large amount of time to make silk fully soak at the in-process that soaks, otherwise appears soaking the inequality and can lead to the epilogue stoving uneven, and then influences the silk quality. The silk packing and unpacking are also very strict, the phenomenon of silk mess needs to be avoided, the process is complicated, and the time and the labor are wasted. And a large amount of time and strict temperature control are required for soaking and drying by adding the auxiliary agent. Therefore, the traditional process is very complicated in each procedure, consumes a lot of time, and if problems occur in each procedure, serious influence can be caused on subsequent processing, even silk is scrapped, the production cost is increased, and the silk quality can be influenced.
At present, more patents propose feasible improvement measures, and the drying and winding process is combined into one process by the aid of the drying and winding integrated equipment for silk processing disclosed in Chinese patent CN104562218A, so that the process is shortened, and a large amount of time is saved; chinese patent CN108796623A discloses a method for processing silk, which adopts manual work to participate in each step, and ensures the quality of the silk without chemical reagent soaking and physical force damage; the silk reeling machine with the auxiliary agent groove disclosed in the Chinese patent CN208362532U integrates silk reeling and wetting, improves the production efficiency and saves the space and the equipment cost.
However, these existing solutions are all improvements to one of the processes or improvements to the processes that can be combined, which simplifies the process and improves the production efficiency, but does not fundamentally change the tedious steps of the conventional silk processing process. In the existing reports at present, how to more effectively improve the silk processing technology and improve the mechanical strength of silk still lacks a practical method. In 2002, a natural magazine, Nature, reports a 'spinning method for fixing the head of a silkworm and carrying out artificial forced traction', and the silk is thinned and the strength is improved to nearly two times by changing the spinning behavior of the silkworm; in 2008, shao huili and the like research 'preliminary research on mechanical properties and structures of tussah silk formed at different spinning speeds', and the result shows that the strength of the tussah silk is improved, and the orientation degree and the crystallinity degree are increased; later, a plurality of researchers have carried out similar researches on silkworms, tussah silkworms and the like, and the research results show that the crystallinity of the silk is increased and the mechanical property is improved by artificial forced traction, but when the traction speed exceeds 40mm/s, the silk is often broken, because the silk spinning behavior is changed after the silkworms are fixed, and the silk is not suitable for the forced traction process to be broken. These studies were directed to individual silkworms and did not attempt to produce silk yarns nor involve an improvement over the conventional silk processing procedure.
