Jersey fabric

When sourcing jersey fabric, the most critical technical factor is the GSM (Grams per Square Meter), which determines the fabric's weight and opacity; typically, 140-160 GSM is ideal for lightweight t-shirts, while 200+ GSM is preferred for premium, heavy-duty garments. Additionally, verify the yarn count (e.g., 30s or 40s)—higher numbers indicate finer, smoother threads. For stretch performance, ensure a Spandex/Elastane content of 5-10% if shape retention is required, and always request pilling resistance test results (Grade 3-4 minimum) to ensure long-term garment durability.

To ensure market access and consumer safety, prioritize suppliers who hold OEKO-TEX® Standard 100 certification, which guarantees the fabric is free from harmful substances. If you are targeting the eco-conscious market, look for GOTS (Global Organic Textile Standard) or GRS (Global Recycled Standard) certifications. For the US market, ensure compliance with CPSIA regarding lead content and flammability, and for the EU, verify that the dyes used are REACH compliant to avoid hazardous chemicals.

Start by requesting a swatch card and a 1-2 meter sample to conduct an in-house shrinkage test; high-quality jersey should have a shrinkage rate of less than 5%. Perform a colorfastness to washing and light test (ISO 105-C06) to prevent bleeding. Furthermore, check for spirality (torque)—a common defect in single jersey where the side seams twist after washing. Professional buyers should utilize third-party inspection services to verify these metrics at the factory before the final balance payment is made.

Single Jersey is the most versatile, widely used for t-shirts, dresses, and innerwear due to its lightness and breathability. Double Jersey (Interlock) is thicker and more stable, making it suitable for sportswear and formal knitwear as it does not curl at the edges. For athletic applications, Technical Jersey with moisture-wicking and anti-bacterial finishes is the industry standard for high-performance activewear.

Dye lot variation is a major risk in textile sourcing. To mitigate this, require the supplier to provide Lab Dips for approval before production and insist on 'One Lot' production for your entire order. Include a clause in your contract stating that all rolls must meet a Delta E (ΔE) color difference value of < 1.0 compared to the approved master sample.

Negotiate based on Total Cost of Ownership (TCO) rather than just the price per meter. For custom colors, the Minimum Order Quantity (MOQ) is usually higher (e.g., 500kg); however, you can negotiate a lower MOQ by choosing 'Ready Goods' (stock colors) from the supplier's existing inventory. On platforms like Made-in-China.com, look for Audited Suppliers to ensure you are dealing with direct manufacturers, which can reduce costs by 10-15% compared to trading companies.

Jersey fabric is susceptible to moisture and pressure damage. Ensure the supplier uses double-layer packaging (inner plastic polybag + outer woven bag) to prevent water ingress during sea freight. Specify that rolls should be stored horizontally and not stacked too high to avoid permanent pressure creases in the knit structure. For international trade, using FOB (Free On Board) terms is recommended to maintain better control over shipping costs and customs clearance agents.

Always use secure payment methods and consider using the Escrow services or trade insurance provided by reputable B2B platforms like Made-in-China.com. Never wire full payments upfront; a standard 30% deposit and 70% balance against the Bill of Lading (B/L) after a successful pre-shipment inspection is the safest practice for B2B buyers.
