Elastic interlock fabric

When evaluating Elastic Interlock Fabric, buyers must focus on GSM (Grams per Square Meter), typically ranging from 200 to 350 GSM for sportswear and leggings. The composition ratio is critical; a standard high-quality blend is 75-85% Polyester or Nylon and 15-25% Spandex (Elastane) to ensure optimal recovery. Additionally, verify the knitting gauge (usually 24G to 32G) to ensure a smooth, 'double-knit' surface that prevents see-through issues when stretched.

Request third-party lab test reports focusing on Four-Way Stretch capabilities and Elastic Recovery Rate (should be >95% after 30 minutes). For functional apparel, ensure the fabric has undergone Moisture Wicking (Quick-Dry) and Anti-Pilling (Grade 4-5) tests. If the end-use is outdoor gear, confirm the UPF (Ultraviolet Protection Factor) rating, ideally UPF 50+, and check for Colorfastness to Perspiration and Washing according to ISO 105 standards.

To enter the EU or US markets, the fabric should ideally hold an OEKO-TEX® Standard 100 certification, ensuring it is free from harmful substances. For brands focusing on sustainability, prioritize suppliers offering GRS (Global Recycled Standard) certified recycled polyester or nylon. Ensure the dyeing process complies with REACH regulations to avoid restricted chemicals like Azo dyes.

Due to its double-knit structure, which provides more stability and thickness than single jersey, it is primarily used for Yoga Wear, Compression Garments, and Professional Sportswear. It is also an excellent choice for Medical Support Bandages and High-End Intimate Apparel where a soft hand-feel and opaque finish are required.

Always request a Lab Dip (A/B/C options) for approval before mass production. For large-scale orders, insist on a 'Golden Sample' from the actual production run. Ensure the contract specifies that the bulk goods must match the approved sample within a Grey Scale rating of 4 or higher.

Leverage volume-based pricing; for Elastic Interlock, prices often drop significantly when ordering over 1,000kg per color. Discuss Lead Times clearly, as customized dyeing usually takes 15-25 days. Ask for 'Stock Lots' if you are a startup looking for lower MOQs, but be aware that color consistency cannot be guaranteed for re-orders of stock items.

Fabric rolls are prone to moisture and pressure damage. Ensure the supplier uses Double-Layer Packaging (inner plastic bag + outer woven bag). Specify that rolls should be shipped on pallets for LCL (Less than Container Load) shipments to prevent deformation. For international trade, FOB (Free On Board) is recommended to maintain control over the main freight costs and carrier selection.

Utilize the Secured Trading services on Made-in-China.com to protect your payments. Never wire full payments upfront; a standard industry practice is a 30% deposit and 70% balance against the Bill of Lading (B/L) or after a successful Pre-Shipment Inspection (PSI) by a third-party agency like SGS or Intertek.
