Advantage:
Viscose rayon is a medium to heavy duty fiber with fair to good abrasion resistance, hydrophilic properties (11% moisture regain), this fiber is dry cleanable and washable with good care It produces static electricity or pilling, and the price is not expensive.
Shortcoming:
Rayon Embroidery Thread: loses 30% to 50% of its strength when wet, so care should be taken when washing, and the strength will recover after drying (Improved Viscose Rayon - High Wet Modulus (HWM) viscose, There is no such problem), the elasticity and resilience of rayon are poor, and it will shrink greatly after washing, and it is also prone to mildew.
1. high strength. The strength of short fiber is 2.6～5.7cN/dtex, and the strength of high tenacity fiber is 5.6～8.0cN/dtex. Due to its low hygroscopicity, its wet strength is basically the same as its dry strength. The impact strength is 4 times higher than that of nylon and 20 times higher than that of viscose fiber.
2. Good elasticity. The elasticity is close to that of wool, and it can almost fully recover when the elongation is 5% to 6%. The wrinkle resistance exceeds other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The modulus of elasticity is 22-141cN/dtex, which is about 2-3 times higher than that of nylon.
3. Heat resistance and thermal stability are the best in synthetic fabrics.
4. Polyester has a smooth surface and tightly arranged internal molecules.
5. Good abrasion resistance. The abrasion resistance is second only to the nylon with the best abrasion resistance, and it is better than other natural fibers and synthetic fibers.
6. Good light fastness. Lightfastness is second only to acrylic.
7. preservative. Resistant to bleaches, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Dilute alkali resistance, not afraid of mildew, but hot alkali can make it decompose.
8. Poor dyeability, but good color fastness, not easy to fade.
