This document discusses different types of sewing threads used in the garment industry. It outlines seven main types: polyester core spun threads, spun polyester threads, staple spun cotton threads, textured polyester threads, polyester cotton core spun threads, embroidery viscose rayon sewing threads, and trilobal polyester threads. For each type, it provides a brief description of the materials and production process used, as well as typical applications. The goal is to provide an overview of common sewing thread options available to the garment industry.

2. SEWING THREADS

3.  Sewing thread is smooth, evenly spun, hard twisted
ply yarn, thread by a special finishing process to make
it resistance to stresses in its passage through the eye
of a needle and through the material involved in
seaming and stitching operation.

4. Type of Sewing Thread in Garment
Industry
 Polyester Core Spun Threads
 Spun Polyester Threads
 Staple Spun Cotton Threads
 Textured Polyester Threads
 Polyester Cotton Core Spun Threads
 Embroidery Viscose Rayon Sewing Threads
 Trilobal Polyester Threads

5. Polyester Core Spun Threads
 This type of threads is produced by spinning polyester
fiber around a core of high tenacity continuous
filament polyester in spinning operation. Two or more
of these composite yarns are then twisted together to
give the necessary size and tensile strength.
 Uses: Mainly use in topstitching of shirts, blouses,
trousers, sportswear, jeans and work cloths.

6. Spun Polyester Threads
 Staple polyester fibers are spun into polyester yarn.
Then two or more polyester yarns are twistted together
to produce spun polyester threads.
 Uses: Mainly used for seaming of shirts, trousers,
knitwear, jackets, blouses etc.

7. Staple spun cotton threads
 Normally long staple cotton fibers are spun into cotton
yarn. Then two or more ply of spun cotton yarn are
twisted together to produce spun cotton threads.
 Mainly used in sewing cotton garments especially for
knitted fabric.

8. Textured Polyester threads
 Made from textured continuous polyester filament.
 Uses: Mainly used in seams of high softness .e.g.
underwear, swimwear, babywear etc.

9. Polyester Cotton Core spun
Threads
 Made of polyester filament in the core and staple
cotton fiber which warps polyester filament. Two or
three of these yarns are twisted together to be thread.
 Uses: fine cotton denim shirts, outdoor wear etc.

10. Embroidery Viscose Rayon Sewing
Threads
 Viscose Rayon is a multiple filament, twisted, high-
sheen continuous fiber thread. It has the bright
appearance.
 Uses: embroidery for garments.

11. Trilobal Polyester Threads
 Newly developed polyester fiber to improve the
dullness of usual polyester fiber.
 Trilobal is a multifilament, twisted, high sheen
continuous fiber thread. It has the same bright
appearance such as rayon, silk. Triangular shaped fiber
reflect more light and give an attractive sparkle to
textiles.
 Uses: embroidery for garments.
