Silk yarn and yarn spun from silk waste; silk-worn gut

cpc code 26310 covers the production and trade of silk yarn and yarn spun from silk waste, as well as silk-worn gut. The silk industry is a vital component of the global textile and apparel supply chain, providing a high-quality, natural fiber that is prized for its softness, luster, and durability. This industry plays a significant role in the economies of major silk-producing countries, generating employment and export revenue.

The production of silk yarn and yarn spun from silk waste involves several key steps. First, silk cocoons are harvested from silk worms, and the raw silk fibers are extracted through a process called reeling. These fibers are then spun into silk yarn, either through traditional hand-spinning methods or using modern, automated machinery. For silk waste yarn, the leftover fibers and byproducts from silk production are collected, cleaned, and spun into a lower-grade yarn. The silk-worn gut is produced by processing the digestive tract of the silk worm.

The main inputs required for the silk yarn and silk waste yarn industry include silk cocoons, which serve as the raw material. Additionally, specialized machinery such as silk reeling machines, spinning frames, and other textile processing equipment are necessary for the production process. The industry also relies on a skilled workforce, particularly in regions where traditional silk production techniques are still practiced.

The primary outputs of cpc code 26310 are silk yarn, yarn spun from silk waste, and silk-worn gut. These products are then consumed by various downstream industries, such as 26400 Woven fabrics, 26500 Knitted or crocheted fabrics, and 28110 Made-up textile articles, which use silk yarn and fabric in the production of high-end textiles, apparel, and other silk-based products.
