Short fiber

When evaluating short fiber (staple fiber), you must focus on denier (fineness) and cut length. For textile applications, a denier of 1.2D to 3D is standard, while non-woven or filling applications may require 6D to 15D. Additionally, verify the tenacity (breaking strength) and elongation rate to ensure the fiber can withstand high-speed spinning or industrial processing without excessive breakage.

Virgin fiber is made directly from PTA and MEG, offering the highest tenacity and color consistency. Recycled fiber (rPET), often made from post-consumer bottles, is more cost-effective and eco-friendly but may have slight color variations. Close Virgin is a high-quality recycled grade that mimics virgin properties. Always request a GRS (Global Recycled Standard) certificate if you are purchasing recycled fibers for sustainability-focused markets.

For apparel and home textiles, ensure the fibers meet OEKO-TEX® Standard 100, which guarantees the absence of harmful substances. If the fiber is intended for the EU market, it must comply with REACH regulations. For specialized uses like flame-retardant upholstery, verify compliance with BS 5852 (UK) or CFR 1633 (US) standards.

Suppliers on Made-in-China.com can often provide functional enhancements such as Anti-bacterial (silver ion), Flame Retardant (FR), Hydrophilic, or Anti-UV treatments. For the filling industry, specify if you need Siliconized (for a smooth, soft hand-feel) or Non-siliconized (for better cohesion in non-woven heat-bonding) fibers.

Short fiber is sold by weight, so moisture regain is a critical risk factor. Standard moisture regain for polyester is 0.4%. Ensure your contract specifies that the net weight is calculated based on a standardized moisture content to avoid paying for water. Always request a pre-shipment inspection (PSI) to verify the bale density and cleanliness to prevent contamination.

Short fiber prices are highly sensitive to raw material costs (crude oil, PTA, MEG). Negotiate based on a formula-based pricing model linked to market indices for long-term contracts. For bulk orders exceeding 20 tons (one 40HQ container), aim for a 5-8% volume discount. Mentioning your sourcing via Made-in-China.com can often help in identifying Diamond Members who offer more stable pricing and verified production capacities.

Fibers are typically shipped in compressed bales (approx. 250kg-350kg each). Ensure the supplier uses high-quality PP woven bags with steel wire strapping to prevent bale bursting during transit. To optimize shipping costs, confirm the loading capacity; a 40HQ container should ideally fit 22 to 25 metric tons depending on the fiber density.

Use Secured Trading Services provided by platforms like Made-in-China.com to protect your payment until shipping documents are verified. For first-time orders, utilize a Letter of Credit (L/C at sight) or a 30% deposit with 70% against the Bill of Lading (B/L) copy. Avoid full upfront payments to unknown suppliers to mitigate the risk of non-delivery or sub-standard goods.
