Tussah Silk Fiber
Nature — What Is Tussah Silk Fiber?
Tussah silk fiber (also spelled Tussar) is a type of wild silk produced by silkworms that feed on natural forest leaves instead of cultivated mulberry leaves. Because the worms are not farm-raised in controlled conditions, the fiber has a more irregular texture.
Like all silk, it is composed mainly of fibroin (a structural protein forming the silk filament).
Scientific Structure (Explained Clearly)
Tussah silk consists of filament fibers (long strands spun by silkworms), but unlike mulberry silk, the filaments are less uniform (due to natural feeding conditions).
Structural Characteristics
- Irregular filament thickness (creates natural texture)
- Triangular cross-section (produces subtle sheen)
- Protein-based composition (fibroin structure)
Fabric Impact
- More textured feel than mulberry silk
- Natural matte-to-soft sheen
- Earthy beige to golden tones
Performance — How Tussah Silk Behaves in Clothing
1. Natural Texture
Irregular filament thickness gives fabrics a slightly slubby (naturally uneven) appearance.
2. Lightweight Comfort
Like other silk types, tussah is breathable and lightweight.
3. Strength
Tussah silk maintains good tensile strength (resistance to pulling force) relative to its weight.
4. Temperature Regulation
The protein fiber structure supports airflow while offering light insulation.
Reality — What Customers Should Know
Advantages
- Natural organic texture
- Subtle elegant sheen
- Breathable and lightweight
- Distinctive earthy tones
Limitations
- Less smooth than mulberry silk
- Requires delicate washing
- Can wrinkle depending on weave
Buying tip: Choose tussah silk if you prefer a more natural, textured look rather than ultra-smooth shine.
