Garment interlining cotton

When sourcing cotton interlining, you must prioritize base fabric weight (GSM) and coating density. For lightweight summer garments, a weight of 30-60 GSM is ideal, while structured coats require 80-120 GSM. Ensure the supplier uses Double Dot coating technology (PA or PES glue) to prevent 'strike-back' or 'strike-through' during the fusing process. Additionally, verify the shrinkage rate; high-quality cotton interlining should have a shrinkage of less than 1.5% to avoid garment distortion after washing.

To ensure market access and consumer safety, products must meet the OEKO-TEX® Standard 100, which guarantees the absence of harmful substances like formaldehyde and azo dyes. For the European market, compliance with REACH regulations is mandatory. If you are targeting the US market, ensure the materials comply with CPSIA standards, especially regarding lead content and phthalates if used in children's apparel.

Request a Peel Strength Test report. A professional supplier should demonstrate a bonding strength of at least 5-10N/2.5cm after multiple wash cycles. You should also confirm the washing resistance; specify whether the interlining needs to withstand 40°C home laundering, 60°C industrial washing, or dry cleaning (perchloroethylene). Always request pre-production samples to conduct a fusing test with your specific outer fabric to check for bubbling or delamination.

Cotton interlining is versatile: Woven cotton interlining is best for shirt collars and cuffs to provide a crisp finish. Non-woven cotton blends are often used for pocket flaps and waistbands for cost-efficiency. For high-end bespoke tailoring, hair interlining (canvas) containing cotton and horsehair is preferred for its superior 'memory' and structural recovery.

Utilize third-party inspection services (such as SGS or Intertek) to perform a During Production Check (DUPRO) and a Final Random Inspection (FRI). Focus on checking the uniformity of the glue dots and the consistency of the fabric color. On platforms like Made-in-China.com, prioritize Audited Suppliers who have undergone comprehensive on-site verification of their manufacturing capabilities and quality management systems.

Interlining is a volume-driven commodity. You can negotiate a 10-15% price reduction by increasing your order to meet the supplier's standard roll length (usually 100m or 500m) to reduce cutting waste. If you are a startup, look for suppliers offering stock-supported programs where the MOQ can be as low as 1-5 rolls, though the unit price may be slightly higher than custom-made orders.

Interlining rolls are susceptible to moisture and pressure deformation. Ensure the supplier uses strong PVC inner tubes and double-layer plastic wrapping with an outer woven bag. For sea freight, request silica gel desiccant packets inside the packaging to prevent mildew during transit. Compare FOB (Free On Board) and CIF (Cost, Insurance, and Freight) terms; FOB is generally recommended for B2B buyers to maintain better control over shipping costs and customs clearance agents.

Always use secure payment methods provided by reputable B2B platforms. For large orders, a 30% deposit and 70% balance against the Bill of Lading (B/L) copy is standard. Avoid direct transfers to private bank accounts. Using the Secured Trading Service on Made-in-China.com can provide an extra layer of protection, ensuring your funds are only released once the shipping documents are verified.
