< p > according to the introduction of science and Technology Office of Guangxi District, for a long time, Guangxi cocoons were unable to produce high-grade raw silk in the industry. The main reason is that Guangxi cocoons are multiple cocoons. The climatic factors of Guangxi determine the characteristics of raw cocoons, resulting in the defects such as the length of the silk thread, the low cleanliness, the large number of nodes and the large reeling of the cocoons in Guangxi.

< p > silkworm clean index can not be improved by general production technology. The application of touch steaming technology at the end of 80s is not suitable for Guangxi silkworm cocoon enterprises to improve cleanliness. The main reason is that the cocoon cocoon layer of Guangxi is too thin, too much steaming will cause excessive dissolution of sericin and cause the cocoon layer to dissociate and peel off. The overdissolved sericin will form a new glue, but it will cause the relaxation of the solution. The uneven steaming will cause the cocoon quality to decline, and the consumption will increase in the scale production. The poor cleanliness of Guangxi cocoons is mainly due to the uneven diameter of the small rings and many cracks.

< p > because of the weak technical foundation, raw silk production is mainly made of low-grade cocoon silk, and the low production capacity of high grade raw silk restricts the development of Guangxi high quality mulberry silk production and the processing industry of mulberry silk, resulting in a single product structure, low level of product, low added value and low market competitiveness of Guangxi silkworm products. Guangxi's cocoon quality has become the "dead point" of producing high-grade raw silk.

< /p >

< p > how to improve the quality of raw silk, occupy the high-grade raw silk market and promote the pformation and upgrading of the silk industry is a difficult problem facing Guangxi silk reeling enterprises.

Helping enterprises to innovate independently, develop new technologies, upgrade Guangxi silk technology status, enhance the use value of Guangxi cocoons and extend the industrial chain has become a means to break through the bottleneck of Guangxi's sericulture development.

< p > "aiming at the characteristics of Guangxi silkworm cocoons, we have explored and studied a new process of steaming new equipment, improved the cocoon cooking equipment, and effectively controlled the cooking degree of cocoon cooking, so as to achieve the goal of improving cleanliness, cleanliness, reducing class sections, improving product quality and reducing raw material consumption. This is a technical problem that Guangxi silk making enterprises urgently need to solve."

Huang Shaoen, specializing in silk, a target= "_blank" href= "http://www.91se91.com/" > textile "/a" specialty, and engaged in 26 years of silk inspection technology and research in Guangxi Bureau, led the team to carry out the research on Key Technologies of cocoon production of high-grade raw silk.

< p > Huang Shaoen said that cocoon cooking is the use of water and heat to make the sericin bentonite soft and reduce the adhesive force between cocoons and silk. When cocoon silk is reeling, the cocoon silk is well separated and the raw silk is successfully reeled.

The control of cocoon boiling time, temperature and steam pressure is the key to cocoon cooking.

In the past, the general cocoon cooking machine was not adapted to the cocoon requirement of the thin cocoon of Guangxi cocoon layer.

The small cocoon raw material was quickly boiled to a semi cooked state, and the cooking condition of the thin cocoon layer was achieved by adjusting the part at low temperature. The raw material of the thick cocoon material was semi cooked, and a movable segment gate was added to the middle section of the three and four sections to increase the temperature difference between each segment to increase the low temperature cooking strength to reach the requirement of suitable cooking for the thick cocoon layer; and the outlet part was extended to adjust the cocoon cooking again, so that the sericin was once again expanded to achieve the goal of smooth dissociation. As a result, the research group developed a multi-function cocoon cooking machine, which first used impregnation and preheating to reduce the pressure difference of thin cocoons directly into low temperature cooking.

The application shows that the multifunctional cocoon cooking machine can adapt to different cocoon layers and cocoons of thick and thin layers, and can effectively control the maturity of cocoon cooking according to the cocoon properties required by different reeling machines, so as to meet the requirements of suitable cooking for producing high grade raw silk in Guangxi cocoon production.

< p > Huang Shaoen said that the research group has developed a device to separate the silk thread from the wet ends of the silk reeling line, and collect and comb the thick threads of the thread through the eccentric disk, and then separate the winding threads from the fine part of the combing thread after finishing the machine. The device is applied to the reeling head, effectively separating the coarse silk and the fine silk in the process of automatic wire and thread processing of the reeling silk, reducing the consumption of the wire and cutting the wire without cutting off, so that the wire can be directly twisted into the wire to improve the application value of the wire.

With the raw materials produced by this technology, Guangxi enterprises have successfully developed new products such as silk carpets, silk sweaters and so on. The device can also reduce the consumption of 5%~8%, increase the value of clean silk by more than two times, and raise the value of the leftovers of tons of silk by 4600 yuan.

< p > technological innovation must be coordinated to form "combined boxing" and improve scientific and technological means.

The steam steaming chamber is designed and used for silk reeling and steaming and delivering cocoon device. Through the rational layout of steam pipes around the steaming room, the track and cocoon delivery truck can be quickly and quickly discharged to ensure the steaming quality, achieve the uniform and stable temperature at each point in the steaming room, and save steam energy at the same time. It also solves the key technology of the uniform cocoon of thin Guangxi cocoons, reduces the ring type, breaks the silk and improves the cleanliness. It applies the steaming equipment to optimize the best steaming process of the Guangxi cocoon, and finally makes the adhesive force of the cocoon layer glue uniform, and solves the problem of cleaning the small ring and split wires, so as to improve the raw material's relaxation rate, cleanliness, cleanliness and other indexes. The research group has developed an efficient and uniform reeling equipment for silk reeling.

It can effectively improve the cleanliness of raw silk by 1~3.71 points, and increase the cleanliness index of raw silk by 1 to 2 grades. The worse the cleanliness is, the more obvious the effect of cleaning is after steaming. It can reduce the loss of steamed steam by about 40%.

< p > Huang Shaoen said that the Key Laboratory of national raw silk and silk products detection of Guangxi Bureau has made great contributions to the research topic.

The head of Guangxi science and technology office said that the research project fundamentally solved the key technical problems of producing high grade raw silk in Guangxi cocoon production, and enhanced the utilization value of Guangxi cocoons. The research equipment and technology contents were highly targeted, and had strong popularization and practicality.

The technology has been applied to all or part of the technology in 32 enterprises in 7 provinces of China. The average grade of raw silk has increased from 0.6 to 1.5 grades. The sales revenue of the project unit has increased by 1 billion 380 million yuan, the new profit has been 97 million 710 thousand yuan, and the export volume has increased by 230 million US dollars.

Among them, 21 enterprises in Guangxi have been used for more than one year, and the scale of production is 13.4 million. The scale of application accounts for 44.7% of the 30 parts of the whole area. The quality of raw silk is increased by 0.6~1.5, a href=, http://www.91se91.com/news/index_f.asp, /a, and 1 to 2 people in each group. The running rate of the platform is obviously improved, the output of Taiwan is increased by 1.5%~3.6%, and the amount of waste per ton is 3 kg to 7 kg.
