What is silk reeling? Silk reeling is a process of drawing silk from cocoons! It is one of the important processes in silk fabric processing and is also an important pre-process! So reeling is a process of drawing silk from cocoons! The reeling process is What? There are many people who don’t know much about the silk reeling process. Today I will introduce to you in detail some knowledge related to the silk reeling process!

Silk reeling technology is a unique silk textile technology in China. This technology has been around 7,000 years ago and the Yangshao Culture has unearthed an earthen spinning wheel. As far as the silk reeling process is concerned, silk and hemp were used at first, and later cotton appeared.

What is the silk reeling process?

The silk reeling process includes the thread of the cooked cocoon, the thread of the cocoon, and the thread of the cocoon silk. , sheathing, reeling, adding and splicing threads when the cocoon silk of some cocoons is finished reeling or broken in the middle, winding and drying of raw silk.

The silk reeling process involves steaming silkworm cocoons at a high temperature of 90 degrees.

Silk reeling is to organize the messy glue silk on the surface of the silkworm cocoon, also known as Zhengxu cocoon!

Jixu is to organize the dry particles of Zhengxu cocoon The process of merging!

Sheath twisting: After the silk thread passes through the yarn collector, upper drum and lower drum, the front and rear sections are twisted together to form a silk sheath

Reeling: Put the Zhengxu cocoon into the reeling soup with a temperature of about 40℃ to reduce the adhesive force between the cocoon silks and dissociate the cocoon silks sequentially. If the strength of the dissociated cocoon filaments is less than the cohesive force between them, ends will break, which is called thread loss. The cocoon that is reeled up to the pupa and becomes lining is called natural falling; the cocoon that is reeled in the middle and becomes silky is called midway falling.

Adding thread and adding thread When the cocoon is finished reeling or the thread is dropped in the middle, in order to maintain the fineness specification of raw silk and continuous reeling, the thread of the prepared cocoon must be added, which is called thread adding. thread. The vertical reeling uses manual threading, the automatic reeling uses mechanical threading, and the threading is completed by the threading device. Since the cocoons of a cocoon vary in thickness, in order to ensure the quality of the raw silk, in addition to ensuring the grain size when adding yarn to the reel, cocoons must also be mixed, that is, a certain proportion of thick-skinned cocoons and thin-skinned cocoons must be maintained for each yarn.

Winding and drying The silk drawn from the silk sheath must be wound into a certain form in an orderly manner. The silk sliver wound on the small thread through the interlacing device is called the small thread silk piece; the silk thread wound on the bobbin is called the bobbin raw silk. But no matter what kind of winding form, drying must be carried out during winding. On the automatic reeling machine, in addition to the above-mentioned procedures, the supply of new cocoons, cocoon feeding, fineness sensing, thread adding and collection, transportation and separation of dropped thread cocoons are all completed by machinery. There are two types of tussah cocoon reeling: dry reeling and water reeling. Dry reeling is to remove part of the water from the cocoon after cooking and bleaching, and when the cocoon is in a moist state, it is placed on the table of the dry reeling machine for reeling; the process of water reeling and standing reeling of mulberry cocoons are basically the same. The cocoons that have been boiled and bleached are directly placed in a water reeling machine pot filled with hot water for reeling.
