A Comprehensive Manual for Understanding Core Spun Yarns – Its Applications and Characteristics

A Comprehensive Manual For Understanding Core Spun Yarns

Core spun yarns are manufactured using industrial polyester yarn. The central core typically consists of continuous polyester filaments, while the outer wrapping comprises staple fibres such as cotton or polyester. The core yarn provides strength and stability to the fabric, while the outer fibres contribute to its appearance and structure. Core spun yarns are used to make specific fabrics required for industrial applications. Because of their unique composition, core spun yarns are preferred for sewing thread solutions. They are suitable for intricate designs and heavy-duty stitching.

Features of Core Spun Sewing Threads

The noteworthy features of core spun sewing threads include the following:


Core spun threads consist of a filament or multifilament core wrapped with staple fibres. The core provides strength and stability, while the outer fibres contribute to the appearance and sewing performance. This combination results in a thread that can withstand high tension, resist breakage, and endure wear and tear during the sewing process.

Extra Long Length

With extra length, core spun threads allow users to sew continuously without worrying about running out of thread. This allows for denser stitching without fear of running out midway through a project. If a strand is broken while sewing, retrieving more yarn from the spool and resuming work seamlessly is easy.

Softness and Comfort

The outer layers of staple fibres in core spun threads add softness and comfort to the thread. This is particularly important for sewing applications involving garments, textiles or any other items that come into direct contact with the skin. The staple fibres offer a pleasant feel and reduce potential irritation.


Core spun threads can be used for apparel and non-apparel sewing projects, including garments, home textiles, upholstery and industrial applications. They are available in different thicknesses and materials, allowing versatility in selecting the right thread for specific sewing applications.

Resistance to Abrasion and Chemicals

With strong abrasion resistance, core spun threads are preferred for applications that involve frequent handling, friction or exposure to rough surfaces. They also offer resistance to chemicals, including washing agents and certain solvents, ensuring the longevity and integrity of stitches.

Various Applications of Core Spun Sewing Threads

With several advantages, core spun sewing threads have numerous applications in the textile industry. They include:

Premium Suits and Trousers

Core spun threads are commonly used to manufacture high-quality suits and trousers. The threads contribute to the durability and longevity of these garments, ensuring that the stitches remain intact even with frequent wear and movement.


Denim manufacturing is another industry where core spun sewing threads are extensively used for stitching purposes. The strength and resilience of core spun threads complement the robust nature of denim fabric, contributing to the longevity and durability of denim.


Swimwear requires threads that can withstand exposure to chlorine, saltwater, and UV radiation and frequent stretching and movement. Core spun sewing threads offer excellent strength and resistance to chemicals and are, therefore, suitable for making swimwear. They contribute to the longevity and durability of swimwear garments.


Whether it’s sportswear, athleisure wear or fitness apparel, these threads provide the necessary strength and flexibility to withstand intense physical activity and repetitive stretching. They help maintain the structural integrity of the garments during movements and washing.

Household Textiles

In household textiles, core spun threads are commonly used in sewing upholstery items such as pillows and sofas, where durability and strength are paramount. These threads ensure that the sewn items can withstand daily usage and maintain their appearance for an extended period.
