The method of core-spinning involves twisting fibers around an existing yarn to create a shell core structure with the already produced yarn as the core. Putting it simply, core spun yarn is manufactured by twisting staple fibers around a central filament core, which is often comprised of polyester for added strength.
Core spun yarn has two parts: the center and the sheath. Continuous filament yarn is often the core, with staple fibers serving as the sheath covering. The core-spun thread improves the fabric’s functional attributes, including strength, durability, and stretch comfort. Therefore, it is used to make core-spun yarn tights and similar products.
How to make Core-Spun Yarn
Spinning is the technique to manufacture this type of yarn. However, there are various processes of spinning to get the same results. Each system has its own features. The conventional ring spinning is economical and straightforward, but the center’s core positioning is difficult. The major strip back problem may arise during the subsequent process, and the core filaments get twisted. In Dref III, the core positioning can be set accurately and used to produce industrial and conductive yarns.
Following are some of the major manufacturing processes:
- Core twin spinning
- Conventional spinning around the core
- Rotor spinning
These are the common ways to manufacture core spun yarn, but there are also some other methods to make this yarn. The end product in all is almost the same. However, the manufacturing and the spinning process is different for each.
Factors Involved in Core Spun Yarn Production
The production of the corn spun yarn is entirely different, making it stronger and unique among all standard yarn. Following are some factors that make core spun yarn better than traditional yarn:
- The core spun yarn uses the method of doubling by using various techniques. Multiple layers are folded on each other, which strengthens the thread.
- The thermal performance of the yarn is also tested and made better using a process called hot stretching. The hot stretching makes the yarn more stretchable; hence, its fabric becomes more durable than standard.
- Lubricating the yarn is also a method in core spun yarn that makes the materials more breathable and provides better cooling in garments.
- Except for all the processes, the thread used to make core spun yarn is also passed through various stress tests to check its durability and prepare it for processing.
Benefits of Core Spun Yarn
It’s 40% to 50% tougher than regular spun yarn of the same weight, and it cuts down on the number of broken stitches while stitching denim seams and hems, which paves the way for clothes that are tougher than normal ones. Similarly, they have exceptional resistance to wear and tear, sewing machine with consistent performance, flexibility for stretch requirements.
In all aspects, the core spun yarn proves to be better than standard yarn. Its toughness and quality improve the fabric’s breathability and durability; all this makes it far superior to traditional yarn. Because of multiple benefits, the core spun thread always stays on the priority list of many big garment companies.
