1. Natural fiber suture
(1) cotton suture
Features: high tensile force, high shape stability, high temperature resistance, poor elasticity, good seamability, large shrinkage
(2) Silk sutures
Features: tough, high elasticity, wear-resistant, suitable for animal fiber fabrics, expensive
2. Synthetic fiber suture
Features: high strength, wear resistance, no shrinkage, anti-mold, limited heat resistance
3. Natural/synthetic fiber mixed suture/blend thread
Features: strong seamability, high tensile force, strong wear resistance
