PET spunbond fabric

When evaluating PET (Polyester) Spunbond non-woven fabric, you must prioritize Gram Weight (GSM), which typically ranges from 15gsm to 260gsm, and Tensile Strength. Unlike PP spunbond, PET offers higher thermal stability (up to 260°C) and superior UV resistance. Ensure the supplier provides data on filament uniformity and hydrophobic or hydrophilic treatments depending on your specific application.

For global markets, the fabric should meet OEKO-TEX Standard 100 for chemical safety and REACH/RoHS compliance for environmental protection. If used in filtration or medical sectors, verify ISO 9001 quality management and specific breathability/filtration efficiency certifications. Always request a Certificate of Analysis (COA) for every batch to ensure consistency.

The application determines the finish: for Roofing and Construction, prioritize high puncture resistance and bitumen compatibility. For Filtration, focus on pleatability and stiffness. For Packaging or Home Textiles, look for printability and soft hand-feel. PET is preferred over PP in scenarios requiring long-term outdoor exposure or high-temperature processing.

Request a pre-production sample and conduct a tearing test and shrinkage test (especially if heat-setting is involved). Check for web evenness by holding the fabric against light; any 'cloudy' patches indicate poor quality. For long-term projects, ask for accelerated weathering test reports to confirm the fabric's lifespan under UV exposure.

The primary risks include material substitution (mixing PET with cheaper recycled content without disclosure) and weight variance (actual GSM being lower than specified). To mitigate this, use Made-in-China.com's Secured Trading services and insist on third-party inspections (like SGS or Intertek) before the final balance payment is made.

Negotiate based on raw material index pricing (Polyester chips). For orders exceeding 5-10 tons, seek a volume discount of 5-10%. Discuss loading optimization; since non-woven fabric is bulky, using vacuum packaging can significantly reduce shipping volumes and lower your Total Landed Cost.

Ensure the supplier uses heavy-duty PE wrap and core protectors to prevent moisture absorption and edge damage during sea freight. Specify FOB or CIF terms clearly. For high-volume buyers, sourcing from clusters in Zhejiang or Guangdong via Made-in-China.com allows for consolidated shipping, which optimizes container utilization.

Always verify the supplier's Business License and Export Qualification on the platform. Be aware of Anti-Dumping duties that some regions (like the EU or India) may impose on Chinese synthetic fibers. Ensure all Harmonized System (HS) Codes (typically 5603) are correctly declared on the Commercial Invoice to avoid customs delays.
