This 40s/3 spun polyester sewing thread from Changshu Longli Thread Co. Ltd. is a three-ply construction with a diameter of 0.22mm, designed for industrial applications. The net weight per spool is 380g, with a gross weight of 400g, and it delivers 8500m of continuous thread. The product is specified for use in tape edge machines, particularly for mattress fabric and side edge material sewing, with the supplier also recommending 20s/3, 20s/2, or 210D/3 variants for comparable tasks.
Spun polyester threads like this are valued for their durability, resistance to shrinking, and colour fastness under industrial washing conditions. The 40s count refers to the yarn fineness, with higher numbers indicating finer threads; this 40s/3 configuration balances strength with smooth stitching in high-speed machinery. Standard industry practice for such threads includes a tensile strength range of 5.0 to 7.0 cN/tex, though the supplier does not specify this value for this listing.
Primary buyers include mattress manufacturers, upholstery workshops, and textile factories requiring consistent performance in heavy-duty sewing. The thread is typically supplied on cones for bulk use, and buyers should confirm compatibility with their machine’s thread tension and needle size. Changshu Longli Thread Co. Ltd. positions this as a reliable option for producers needing long, uninterrupted thread lengths for automated processes.

Before ordering, verify the thread’s compatibility with your sewing machinery by checking the needle size and thread tension requirements. Ensure the 0.22mm diameter and 380g spool weight align with your production setup, as mismatches can cause downtime or damage to equipment.
Confirm the Incoterms, lead time, and payment terms with Changshu Longli Thread Co. Ltd., as these are not specified in the listing. Bulk shipments from China often use FOB or CIF terms, with lead times varying based on order size and production schedules. Request a proforma invoice for clarity.
For quality assurance, ask for a certificate of compliance for colour fastness (ISO 105) and tensile strength. Conduct a pre-shipment inspection to verify spool weights, lengths, and thread integrity. Document the batch number for traceability in case of post-delivery issues.
