What is the production process of silk?

1. Reeling Silk reeling is a main process in the silk making process.

According to the product specifications, the cocoon silk from several cooked cocoons is dissociated and combined to make raw silk or tussah silk.

It can be divided into three types: floating reeling, semi-sinking reeling and sinking reeling. The floating and sinking of silkworm cocoons mainly depends on the amount of water absorbed in the cocoon cavity after cooking.

According to the different types of silk reeling machinery, it can be divided into two types: vertical reeling and automatic reeling.

The process of extracting silk from silkworm cocoons is generally called silk reeling.

2. Weaving Raw silk is divided into warp and weft threads after processing, and they are interwoven according to certain organizational rules to form silk fabrics, which is the weaving process.

The production processes of various types of silk fabrics are different, and they can be roughly divided into two categories: raw weaving and cooked weaving.

3. Dyeing and finishing Dyeing and finishing refers to the process of chemical treatment of textile materials. It is also commonly known as printing and dyeing in modern times.

Dyeing and finishing, together with spinning, weaving or knitting production, form the entire process of textile production. The quality of dyeing and finishing has an important impact on the use value of textiles.

The process mainly includes the refining, bleaching, dyeing, printing and finishing of raw silk and fabrics.

Extended information: When silkworms spin silk, they spin out two silk threads at the same time, but after solidification, they merge to form one cocoon thread.

The cross section of cocoon silk resembles glasses.

Each cocoon silk contains two silk fibers bonded together by sericin, called silk fibroin, which is glue-free silk fiber.

It has a nearly triangular cross-section, but its shape and cross-sectional area are not uniform.

Sericin is wrapped around silk fibroin fiber, and its presence will have an important impact on the use, processing and product style of the fiber.

The sericin content on each cocoon silk is not uniform. The silk spun out at the beginning has low sericin content, and the silk spun out at the end has the highest sericin content.

Silk fiber has a relatively complete fibril structure, which can fully express the excellent qualities of natural fibers.
