Polyester open end yarn

When evaluating OE yarn, focus on Yarn Count (Ne), which typically ranges from 6s to 30s for open-end processes. You must verify the Tenacity (cN/tex) to ensure it meets your weaving or knitting strength requirements; high-quality OE yarn should maintain a tenacity of at least 12-15 cN/tex. Additionally, check the Twist Per Meter (TPM) and Uster Statistics (CV%) for evenness, as high irregularity leads to fabric defects.

For denim production, prioritize yarn with high abrasion resistance and specific dye uptake consistency. For towels or mops, look for high-absorbency blends or recycled polyester options. Always request a knitting or weaving trial report from the supplier to confirm the yarn's performance on high-speed machinery to avoid frequent yarn breakages.

Ensure the supplier holds the OEKO-TEX® Standard 100 certification, which guarantees the yarn is free from harmful substances. If you are marketing 'eco-friendly' products, the Global Recycled Standard (GRS) certification is essential to verify the recycled content. For quality management, the factory should be ISO 9001 certified.

Request a Transaction Certificate (TC) for every batch of recycled yarn to ensure traceability. Virgin polyester typically offers higher brightness and better tenacity, while recycled yarn may have slight color variations. Perform a burn test and microscopic analysis during third-party inspections to confirm the material composition matches the proforma invoice.

The biggest risks include moisture regain fraud (where yarn is weighed while damp to increase billable weight) and batch-to-batch color shading. To mitigate this, specify a standard moisture regain of 0.4% to 3% in the contract and use Made-in-China.com's inspection services to verify net weight and color consistency before shipment.

Yarn prices are highly sensitive to raw material (PTA/MEG) market fluctuations. Negotiate a formula-based pricing model for long-term contracts. For MOQs, while standard containers (20GP/40HQ) are preferred for shipping efficiency, you can negotiate a trial order of 1-5 tons if you agree to use the supplier's stock colors.

Yarn cones are susceptible to crushing and humidity. Insist on palletized packaging with plastic shrink wrap and corner protectors. Ensure the containers are lined with desiccant bags to prevent 'container rain' which causes mildew. For shipping to regions with high tariffs, verify the Rules of Origin to utilize relevant Free Trade Agreements (FTAs).

Always use Secured Payment services provided by reputable platforms like Made-in-China.com to ensure funds are only released upon proof of shipment. Avoid direct transfers to private bank accounts. For large volumes, consider a Letter of Credit (L/C at sight) to protect both parties against non-performance.
