The process of extracting silkworm cocoons is called silk. The original method of silk reeling is to soak the silkworm cocoons in the hot pot soup, and by hand drawing and winding on the silk basket. Pots and baskets are the original silk tools.
In the long run, the silk thread tool has been improved slowly. Until the end of the Qing Dynasty, the silk thread in the Shanghai area has been improved. The Zhejiang Qili silk car has no twisting device. Therefore, the thickness of the wire is uneven and the head is broken (no joint). It is not compatible with the requirements of large-scale woven production.
In the 11th year of Qingfeng (1861), Shanghai first built a steam-powered modern silk reeling factory, Yihe Yangxing Spinning Bureau. In the 1880s, Huashang Huang Zuoqing founded the office and Yong Machinery Reeling Factory in Shanghai. Since then, the silk that the machine pulled out (commonly known as the factory wire, the quality is better than the earthen silk) is gradually replacing the silk from the rural soil (commonly known as the soil). At that time, the silk reeling factory took the tanning system as the central process, and carried out the sample and process design of the cocoon in each producing area, after mixing (mixing different dry simmering process designs in proportion) and peeling off (peeling the ranunculus surface) The soft coat layer makes it a light 茧 〠〠茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧 茧Boiled 茧 (heating or adding auxiliaries, etc., so that the appropriate expansion and dissolution of sericin), crepe, re-shake (send the smashed small silk to the complex car to process and shake, dry, become a large wire ), and then through the knitting (to the large pieces of silk), tie, weigh, light (color under the light), packaging, into pieces, and through the raw silk inspection, according to the standard by quality and so on.
The silk reeling equipment used in various early silk reeling factories in Shanghai was purchased from France (two-in-one) and Italy (4 to 6 single-draw), steam-powered, and provided a heat source for cooking and drying. . The reeling car is blocked by 1 person/person, and each of the two reeling cars is equipped with a pot (Suoxu, which leads to the silkworm from the dissolved cocoon). In the early 1930s, the Global Iron Factory successfully produced the earliest vertical reeling car in China. After the 26th year of the Republic of China (1937), Shanghai's new factory and the old factory Yihe Silk Factory used new circulating boilers, stripping machines, vertical twisting machines and blackboard machines. The quality and economy of these plants. The benefits are better than other plants. At that time, the design and manufacture of the Shuanggong Silk Car was successfully carried out by the returning personnel from Japan. The car was picked up by the silk factory and could not be reeled by the Shuanggong Temple. In 1951, the first textile machinery factory copied the first domestic D-101 automatic silk reeling machine (automatically added), and the production efficiency was 1.5 times higher than that of the vertical car. Each group (400 threads) only managed 6-8 people. However, other equal-sized cars are managed by 20 people. In the 1950s, the Dali Silk Factory and the Shanghai Institute of Biology of the Chinese Academy of Sciences jointly studied the dissolution of sericin with sodium dihydrogen phosphate. The temperature can be reduced by nearly 50% compared with the original high temperature soup, which is reduced from 210 °C to 120 °C, which not only saves energy, It can protect the outer layer of silkworm cocoons and evenly dissolve the middle and inner layers to improve the relaxing effect. The factory has also innovated and promoted the selection and stripping of the joint machine, replacing the original manual selection and stripping of the garment with mechanized semi-automatic, reducing the labor intensity of the workers and increasing the output by 6 times.
After the founding of New China, the Luobinhan brand white factory silk produced by Shanghai Silk Factory has 60 kg per piece, which is basically supplied to various silk weaving factories in Shanghai. Since 1956, it has been inspected and manufactured according to the 1955 International Raw Silk Classification Standard of the Commodity Inspection Bureau of the Ministry of Foreign Trade.
In the mid-1970s, in order to make the silk yarn directly into a bobbin supply silk weaving factory, Shanghai Silk Silk Factory (formerly Da Li Silk Factory) and Shanghai Textile Science Research Institute trial-produced 18-spindle silk reeling machine. Approved on March 9, 1977.
