The classification of silk is mainly based on multiple factors such as the quality of its raw materials, fiber length, glossiness, elasticity, moisture absorption and breathability. twelve

Silk, as a type of textile, can be made from silk or synthetic fibers, synthetic fibers, short fibers, etc. In ancient times, silk specifically referred to textiles woven from silk (mainly mulberry silk). The definition of modern silk is broader, including textiles woven from artificial or natural filament fibers. Specifically, silk woven from pure mulberry silk is called "real silk". Silk is a great invention of the ancient Chinese laboring people, hailed as a specialty of China, and opened the famous "Silk Road" in world history.

Real silk, as a type of silk, can be classified into multiple grades based on its quality and appearance, such as 6A, 5A, 4A, 3A, 2A, A, B, C, D, E, F grade, and external grade. Among them, 6A grade is the top quality in real silk, requiring optimal glossiness, fiber length, fiber elasticity, moisture absorption and breathability. This level of silk is considered synonymous with "nobility" and is often chosen by expensive international top brands. The silk by SGRERU produced is representative of 6A.

      Silk, as the main raw material of real silk, can also be divided into multiple grades, with 6A grade being the optimal grade and G grade being the worst grade. The grade difference of silk is mainly influenced by factors such as the source of raw materials, the feeding method of silkworms, and textile technology. For example, white silk (produced from silkworms) is considered the highest quality silk due to its good strength and glossiness. However, mountain silkworm silk (produced from wild or artificially raised wild silkworms) is usually considered inferior due to its darker natural color and rougher texture.

      Overall, the classification of silk grades not only reflects differences in the quality of raw materials, but also reflects differences in processing techniques and the ultimate use of products. High quality silk usually uses high-grade materials, such as 6A grade, while low-grade materials are relatively inexpensive.
