9D Spandex Yarn AA Grade

For 9D spandex yarn, being a finer denier, it may offer greater softness and comfort, making it suitable for lightweight and form-fitting garments. Its fineness allows for a more even distribution in fabrics, potentially providing better elasticity and comfort. However, specific physical parameters and performance may vary depending on the manufacturer and production process.

We adhere to international standards and are proud to offer our spandex yarn with certifications such as Oeko-Tex Standard 100, ensuring it is safe for human use and environmentally friendly.

9D SPANDEX YARN CARTONS

• High Elasticity: Spandex can stretch up to 6-7 times its original length and quickly return to its initial state.
• Resistance to Chemical Degradation: It is more resistant to chemical degradation than latex, with a moderate thermal stability and a softening temperature above 200°C.
• Durability: Spandex has good resistance to acids and alkalis, sweat, seawater, dry cleaning, and abrasion.
• Dyeability: It can be dyed using most dyes and finishing agents suitable for synthetic and natural fibers, exhibiting good resistance to chemicals.
• Physical and Mechanical Properties: Spandex has a high elongation rate (500%-700%), low modulus (0.04-0.12 grams/denier at 200% elongation), and a high elastic recovery rate (95%-99% at 200% elongation).
• Tensile Strength: The tensile strength of spandex is relatively low, ranging from 0.44-0.88 CN/dtex, with polyether type spandex being stronger than polyester type.
• Moisture Absorption: Spandex has a low moisture absorption range, generally 0.3-1.2%, with multifilament spandex absorbing slightly more moisture than monofilament.
• Heat Resistance: Most spandex fibers can be stored for a short time in the 90-150°C range without damage, and the safe ironing temperature is below 150°C.
