  3. Sewing Thread (Contd.) Sewing Thread (Contd.) 1. 1.Polyester Corespun Thread: Polyester Corespun Thread: This type of thread is produced by spinning staple This type of thread is produced by spinning staple polyester fibre around a core of high tenacity continuous polyester fibre around a core of high tenacity continuous filament polyester in yarn-spinning operation. Two or filament polyester in yarn-spinning operation. Two or more of these composite yarns are then twisted together more of these composite yarns are then twisted together to give the necessary size and tensile strength. to give the necessary size and tensile strength. e.g. Epic(Coats). e.g. Epic(Coats). Uses: Mainly used in topstitching of shirts, blouses, Uses: Mainly used in topstitching of shirts, blouses, trousers, sportswear , jeans & work clothes. trousers, sportswear , jeans & work clothes.

  4. Sewing Thread (Contd.) Sewing Thread (Contd.) Key Characteristics Key Characteristics: : Exceptionally strong. Exceptionally strong. - The continuous filament core (Having high tenacity) The continuous filament core (Having high tenacity) provides superior strength while the staple polyester provides superior strength while the staple polyester cover helps to protect the inner core from damage due to cover helps to protect the inner core from damage due to needle heat. needle heat. - Its resistance to abrasion helps ensure long seam life in Its resistance to abrasion helps ensure long seam life in a wide variety of materials. a wide variety of materials. - Fine threads can be used for delicate fabric without Fine threads can be used for delicate fabric without compromising on strength, thereby avoiding problems compromising on strength, thereby avoiding problems like seam pucker. like seam pucker. -

Then Staple polyester fibres are spun into polyester yarn. Then two or more of spun polyester yarns are twisted together to two or more of spun polyester yarns are twisted together to produce spun polyester thread. produce spun polyester thread. e.g. Astra (Coats) e.g. Astra (Coats) Key Characteristics: Key Characteristics: - High tenacity of polyester ensures greater strength and High tenacity of polyester ensures greater strength and thereby high abrasion resistance. thereby high abrasion resistance. - Very least amount of shrinkage (less than 1%) compared Very least amount of shrinkage (less than 1%) compared to cotton thread. to cotton thread. Uses: Uses: Mainly for overedging. Also used for general seaming Mainly for overedging. Also used for general seaming of shirts, trousers, knitwear, jackets, blouses etc. of shirts, trousers, knitwear, jackets, blouses etc.
