Spun Polyester Sewing Thread

Designed for precision stitching with low elongation and UV-resistant performance—perfect for denim, upholstery, bedding, formalwear, and drapery.

Product overview

Spun Polyester Sewing Threads from Mahalaxmi combine the strength of continuous polyester filament with a spun finish for superior appearance and handling. The result is a thread that offers very low elongation, high modulus, and UV resistance, delivering precise, uniform seams in a wide range of fabrics without compromising durability or look.

The spun construction adds a soft, tactile finish, making it ideal for visible stitching on apparel (e.g., suits, dresses), home textiles (e.g., cushions, drapes), and bookbinding. With excellent colorfastness and minimal fraying, this thread is compatible with both high-speed and standard industrial sewing machines, delivering consistent spool-to-spool quality.

Available in multiple deniers and over 500 shades (including UV‑stable formal and upholstery tones), our spun polyester thread stands up to the demands of manufacturers who need seams that look good, perform well, and require little to no rework.
