Plain woven interlining

Buyers should focus on base fabric composition (typically 100% Polyester or T/C blends) and coating material (PA, PES, or HDPE). The weight (GSM) is critical; lightweight (20-40g) is for silk/chiffon, while heavyweight (80g+) is for coats. Ensure the coating density (mesh) is uniform to prevent 'strike-back' or 'strike-through' during the bonding process.

Perform a shrinkage test to ensure the interlining matches the outer fabric's rate (ideally <1%). For heat-sensitive fabrics, select low-temperature fusible interlining (bonding at 110-120°C). Always request a peel strength test report to verify the bond remains secure after multiple wash cycles or dry cleaning.

For global trade, prioritize suppliers with OEKO-TEX® Standard 100 certification to ensure the adhesive is free from harmful chemicals like formaldehyde. If exporting to the EU, verify REACH compliance. For children's wear in the US, ensure the product meets CPSIA lead and phthalate requirements.

It is primarily used for structural reinforcement in garment construction. Common applications include shirt collars and cuffs for crispness, suit front panels for shape retention, and waistbands for stability. It is also widely used in embroidery backing and hat manufacturing to provide necessary stiffness.

Request pre-shipment samples from the actual production lot, not just generic showroom samples. Utilize third-party inspection services to check for 'yellowing' (oxidation) and coating consistency. On Made-in-China.com, prioritize Audited Suppliers who have undergone on-site verification of their manufacturing capabilities.

Negotiate based on Total Linear Meters rather than just price per meter. Ask for volume-based tiered pricing (e.g., discounts at 5,000m, 10,000m). Discuss packaging requirements—ensure rolls are wrapped in double-layer moisture-proof plastic to prevent adhesive degradation during humid sea transit.

Interlining is relatively light but bulky; use vacuum compression packaging if possible to reduce freight volume. Ensure the HS Code (typically 5903 or 5208) is correctly declared to avoid customs delays. For large orders, FCL (Full Container Load) is recommended to prevent crushing damage that often occurs in LCL (Less than Container Load) environments.

Use secured payment terms such as Letter of Credit (L/C) for large volumes or Escrow-based services provided by reputable platforms. Avoid direct wire transfers to private accounts. Ensure the Proforma Invoice (PI) clearly states the technical tolerances (e.g., +/- 2g on weight) to provide legal recourse in case of disputes.
