Silk dupion (also known as dupion silk or lumpy silk) is a special silk fabric spun from dupion cocoons (cocoons spun by two silkworms). Its core qualities stem from its unique raw material structure and craftsmanship. The following is a summary of its key features:
Raw Material and Structural Characteristics
1. Natural Texture
Duplicate cocoons are formed by two silkworms spinning silk in a confined space, where the threads intertwine and entwine, creating irregular dot-like, bamboo-like, or lumpy bumps ("truncation"). These textures are considered stylistic features rather than flaws in textiles, giving the fabric a unique three-dimensional quality and rugged aesthetic.
2. Thicker and Stronger Silk Threads
Dupion silk is 30%–50% thicker than ordinary mulberry silk and has a higher fiber strength (a single strand has a breaking strength of 4.43 cN), making the fabric more durable and tear-resistant.
Appearance and Tactile Characteristics
1. Unique Gloss and Three-Dimensional Appearance
The surface exhibits a restrained, soft matte finish. Under light, the shading creates a gradation of light and dark, creating a low-key, elegant three-dimensional effect, distinct from the smooth sheen of ordinary silk.
2. Thick, Crisp, and Soft
The dense, thick texture (19–40 momme thickness) provides a soft yet firm feel. It drapes well without being flimsy, making it ideal for creating a sleek silhouette.
Performance Characteristics
1. Superior Loft and Warmth
Due to its mesh-like interlaced structure (common silk is thread-like), the double-palace silk boasts a 30% higher compression rebound, resulting in a high loft and resistance to compaction when filling bedding, offering superior warmth retention compared to ordinary silk.
2. Enhanced Silk's Common Advantages
Moisture-Absorbent and Breathable: 1.5 times more absorbent than cotton and 20% more moisture-releasing, keeping you dry and comfortable.
Skin-Friendly and Healthy: Contains 18 amino acids to promote skin metabolism, making it suitable for sensitive skin and baby products.
Natural Protection: UV-resistant, flame-retardant (curls and extinguishes itself in flames), and anti-mite and antibacterial.
