Core Spun Polyester Sewing Threads (Poly/Poly & Poly/Cotton)
Core yarns are a combination of staple fiber and continuous filament. The most common core yarn structure is multi-ply. Each layer of the yarn is produced by winding cotton or polyester fiber on endless filament polyester.
In this yarn structure, the strength of the filament polyester in the center of the yarn and the natural appearance provided by the cotton or polyester fiber wrapped around it and its effect on needle cooling positively affect the sewing performance. Looped sewing threads are used in high-speed sewing machines, in all types of clothing, especially in products that require high sewing tenacity.
While it is preferred in the weaving sector, it is also preferred in the works that require high tenacity such as denim, suits, shirts, silk clothes, leather clothes, uniforms and many other product ranges according to the fabric thickness, while at the same time it provides the opportunity to obtain high production performance during the sewing process.
While it provides tenacity in thick groups, it eliminates the problem of hairiness after washing as it has thinner and less hairiness than staple fiber polyester in thin groups, in addition to that since shrinkage is minimized, it largely eliminates the seam puckering problem after ironing other processes with heat treatments. It allows the use of finer needles and gives the seam a more aesthetic appearance.
