Lycra fabric

Selecting the correct blend is critical for performance. For activewear and leggings, a blend of 75-85% Polyester or Nylon with 15-25% Spandex is standard to ensure high compression and 'squat-proof' density. For casual apparel, a lower ratio of 3-5% Spandex mixed with cotton provides sufficient comfort stretch. Always verify the GSM (Grams per Square Meter); a weight of 220-300 GSM is preferred for professional athletic gear to prevent transparency.

High-quality Lycra must demonstrate excellent elastic recovery, meaning it returns to its original shape after stretching without 'bagging.' Ensure the supplier complies with OEKO-TEX Standard 100, which guarantees the fabric is free from harmful chemicals. For recycled options, look for the Global Recycled Standard (GRS) certification. Additionally, check for colorfastness to perspiration and washing (Grade 4 or higher) to ensure the fabric doesn't bleed during intense workouts.

Depending on the end-use, you should request specific functional finishes. Moisture-wicking treatments are essential for sportswear to move sweat away from the skin. Anti-bacterial and anti-odor finishes (such as silver ion technology) enhance the longevity of the garment. For outdoor or swimwear applications, ensure the fabric has a UPF 50+ rating for UV protection and chlorine resistance to prevent fiber degradation in pools.

Always request a pre-production sample (PPS) for lab testing before the full run begins. Utilize third-party inspection services (like SGS or Intertek) to perform a 4-Point System inspection on the rolls before shipment. This system evaluates defects per 100 square yards, ensuring you don't pay for unusable material. On Made-in-China.com, prioritize Audited Suppliers who provide comprehensive factory inspection reports.

Lycra is sensitive to heat and pressure. Ensure the supplier uses hard paper tubes for rolling to prevent creasing and wraps each roll in double-layer plastic bags to protect against moisture during sea freight. Instruct the logistics provider to avoid stacking too many layers high in the container, as excessive pressure can cause the elastic fibers to lose their 'bounce' or create permanent fold marks.

Fabric prices are often tied to raw material costs (PTMG and MDI) and order volume. For custom colors (Lab Dips), the MOQ is typically 500-1000 meters per color. To reduce costs, ask for 'Ready Goods' or stock colors if your volume is low. When negotiating on Made-in-China.com, discuss Incoterms clearly (FOB vs. CIF) and ask for a discount on orders exceeding 3,000 meters, which usually triggers a lower production tier price.
