Mulberry Silk Fiber
Nature — What Is Mulberry Silk Fiber?
Mulberry silk fiber is the highest-grade silk produced by silkworms (Bombyx mori larvae) that are fed exclusively on mulberry leaves. This controlled diet results in uniform, smooth, and long continuous filaments.
Mulberry silk is composed mainly of fibroin (a strong structural protein forming the silk filament), with sericin (a natural binding protein) removed during processing.
Scientific Structure (Explained Clearly)
Mulberry silk consists of continuous filament fibers (long unbroken strands rather than short fibers). Its triangular cross-section (a prism-like microscopic shape) reflects light, creating natural shine.
Structural Characteristics
- Uniform filament length (smooth consistent strands)
- Fine fiber diameter (enhances softness)
- Protein-based fibroin core (gives strength)
Fabric Impact
- Exceptionally smooth hand feel
- High natural luster
- Elegant fluid drape
Performance — How Mulberry Silk Behaves in Clothing
1. Superior Smoothness
The consistent filament structure creates a refined surface that feels soft against the skin.
2. Shine & Appearance
Its triangular fiber shape reflects light evenly, producing luxurious natural luster.
3. Lightweight Strength
Mulberry silk has strong tensile strength (resistance to pulling force) for its weight.
4. Temperature Regulation
Silk allows airflow while providing light insulation, supporting comfort across seasons.
