Stretch fabric

When evaluating stretch fabric, the most critical factor is the composition ratio, typically a blend of polyester or nylon with 5% to 20% Spandex (Elastane). You must verify the GSM (Grams per Square Meter) to ensure the weight matches your application—lightweight (150-200 GSM) for leggings or heavyweight (280+ GSM) for compression gear. Additionally, prioritize fabrics with 4-way stretch capabilities rather than 2-way to ensure maximum mobility and shape retention.

For B2B procurement, always request OEKO-TEX® Standard 100 certification to guarantee the fabric is free from harmful substances. If you are targeting the EU market, ensure compliance with REACH regulations. For functional textiles, ask for third-party lab reports (SGS or Intertek) covering colorfastness to perspiration, pilling resistance (Grade 4 or higher), and dimensional stability after multiple wash cycles to prevent shrinkage.

To differentiate your products, seek suppliers on Made-in-China.com who offer value-added finishes such as Moisture Wicking (Quick-Dry), Anti-Bacterial/Anti-Odor treatments, and UPF 50+ UV protection. For sustainable collections, inquire about Recycled Polyester (rPET) options certified by the Global Recycled Standard (GRS), which is increasingly demanded by eco-conscious consumers.

Request a stretch and recovery test report. A high-quality stretch fabric should have a recovery rate of at least 95% after being stretched to its limit. This prevents the 'bagging' effect at knees and elbows. Furthermore, check the denier count of the yarns; higher denier typically indicates better durability and less transparency (squat-proof) in activewear.

The primary risk is color shading (dye lot variation) between the approved sample and the bulk production. To mitigate this, specify a Lab Dip approval process and require the supplier to use Pantone TCX/TPG codes. Another risk is 'width loss' during shipping; ensure the contract specifies the usable width (excluding selvage) to avoid material wastage during cutting.

Stretch fabrics often have high MOQs (Minimum Order Quantities) due to dyeing vat requirements (typically 500m-1000m per color). You can negotiate by consolidating different styles using the same base greige fabric or by paying a small-batch dyeing surcharge for trial orders. Always request tiered pricing based on volume to understand your scaling potential.

Fabric rolls are prone to moisture damage and deformation. Ensure the supplier uses double-layer packaging (inner plastic bag + outer woven bag). For shipping to the US or Europe, clarify the Incoterms (FOB vs. DDP); for large volumes, Sea Freight is most economical, but ensure the container is inspected for leaks to prevent mildew growth during the transit of synthetic fibers.

Utilize the Secured Trading services provided by Made-in-China.com to protect your payments. Before placing a large order, conduct a factory audit or hire a third-party inspector to verify the supplier's knitting and dyeing capacity. Never release the final payment until you have received and reviewed a Pre-Shipment Inspection (PSI) report confirming the yardage and quality.
