Import 150d/3 Raw White Polyester Thread — Buy in Bulk from Supplier in China

This 150D/3 raw white polyester thread from Changshu Longli Thread Co. Ltd. is a three-ply sewing thread with a denier of 150, engineered specifically for industrial mattress and bedding production. The supplier notes it is the standard recommendation for mattress side decoration sewing, often used alongside 210D/3 and 20S/2 variants. For quilting machines used in bedding shell fabric, this 150D/3 thread serves as the top thread, paired with heavier bottom threads such as 300D, 40S/2, or 40S/3.

Polyester sewing thread in this denier class typically offers tensile strength suitable for high-speed industrial machines, good colour fastness, and resistance to abrasion during repeated needle passes. The raw white (undyed) form is commonly used where the thread will not be visible in the finished product or where subsequent dyeing of the assembled item is planned. Typical industry specifications for 150D/3 polyester thread include a ticket size of approximately 60, elongation at break in the 14-20% range, and packaging on cones or tubes of 500g to 1kg.

Buyers in mattress manufacturing, bedding production, and upholstery are the primary users of this thread weight. The supplier is based in Changshu, Jiangsu, a region with a strong textile manufacturing base.
