What are the ingredients of mulberry silk?
Mulberry silk is a natural protein fiber made from mulberry silkworm (scientific name:Bombyx mori) is formed by solidifying the silk fluid secreted during spinning and cocooning. Known as the "Queen of Fibers", it is widely used in high-end clothing, home textiles and medical fields because of its excellent properties such as softness, smoothness, breathability and moisture absorption. This article will analyze in detail the chemical composition and structural characteristics of mulberry silk and its comparison with other fibers.
1. Main components of silkworm silk
The main component of mulberry silk is protein, accounting for 70%-80%, and the rest is a small amount of water, fat, minerals and pigments. Its protein is composed of 18 kinds of amino acids, among which alanine, glycine and serine are the main ones. The following is the main chemical composition list of mulberry silk:
| Element | Proportion | effect |
|---|
| Protein (silk fibroin) | 70%-80% | Provides fiber strength and elasticity |
Wrong| Sericin | 20%-30% | Wrapped silk fibroin, binding fiber | clear

| fats and waxes | 0.5%-1.5% | Increases gloss and antistatic properties |
| Minerals | 0.5%-1% | Trace amounts of inorganic salts |
2. Structural characteristics of mulberry silk
The fiber structure of mulberry silk is divided into three layers: the outermost layer is sericin, the middle layer is silk fibroin, and the innermost layer is silk core. Sericin is easily soluble in hot water, so it is removed during silk processing, leaving pure silk fibroin fibers. Here's how mulberry silk compares to other natural fibers:
