100%polyester spun yarn

Buyers should focus on the yarn count (e.g., 20s, 30s, 40s), which determines the thickness and application. High-quality yarn must have high tensile strength (tenacity) to prevent breakage during high-speed weaving or knitting. Additionally, check for low hairiness and twist per meter (TPM) consistency, as these factors directly impact the smoothness and pilling resistance of the final fabric. Ensure the moisture regain is within the standard range of 0.4% to 0.5%.

To ensure safety and environmental compliance, prioritize suppliers with OEKO-TEX® Standard 100 certification, which guarantees the yarn is free from harmful substances. For sustainable sourcing, look for the Global Recycled Standard (GRS) if you are purchasing recycled polyester. Furthermore, ISO 9001 certification is a baseline requirement to ensure the manufacturer maintains a consistent quality management system.

Request a lab dip or sample to test for colorfastness to washing, light, and rubbing (crocking), aiming for a grade of 4.0 or higher on the grayscale. For 100% polyester, ensure the supplier uses high-temperature and high-pressure dyeing techniques to achieve uniform color absorption and prevent batch-to-batch color deviation, which is critical for large-scale garment production.

20s to 30s counts are commonly used for heavy fabrics, towels, and workwear, while 40s to 60s counts are ideal for sewing threads, bed linens, and lightweight apparel. Understanding the end-use is vital for selecting the correct spinning method, such as Ring Spinning (for strength and smoothness) or Open-End Spinning (for cost-efficiency in coarser yarns).

Always conduct a pre-shipment inspection (PSI) through a third-party agency to verify the net weight, yarn count, and moisture content. Since yarn is sold by weight, ensure the commercial weight is calculated based on the standard moisture regain to avoid paying for excess water weight. Using platforms like Made-in-China.com allows you to select Audited Suppliers who have undergone rigorous on-site verification.

Polyester prices are highly sensitive to raw material (PTA and MEG) fluctuations and oil prices. Negotiate a formula-based pricing model for long-term contracts. For Minimum Order Quantities (MOQ), suppliers usually require 1 to 3 tons per color; however, you can negotiate lower MOQs for raw white yarn compared to custom-dyed yarn. Consolidating orders into Full Container Loads (FCL) can reduce shipping costs by 15-20% compared to LCL.

Yarn is susceptible to moisture and odors during sea transit. Ensure the supplier uses heavy-duty PP woven bags or cartons with inner plastic liners and requests dry containers from the shipping line. For shipping to specific regions, verify the Rules of Origin to benefit from Free Trade Agreements (FTAs), which can significantly reduce or exempt import duties.

Utilize Secured Payment services provided by reputable trade platforms to ensure funds are only released after confirmation of shipment. For large orders, use Letters of Credit (L/C) or Telegraphic Transfer (T/T) with a deposit (typically 30%) and the balance against the Bill of Lading (B/L) copy. Avoid transferring funds to private bank accounts; always use the official corporate account verified on Made-in-China.com.
