JapanThe present invention relates to a method of manufacturing a compound core spun sewing thread. This sewing thread has high static and heat resistance and is suitable for high-speed sewing. It can be used in a variety of sewing applications. In particular, the high-strength thread can be used to sew heavier garments. Further, the thread can be dyed or color-dyed in an environmentally friendly manner.
The main features of core spun sewing thread are its superior stitchability and strength, resulting in a superior seam. It also offers better thread formation and minimizes seam puckering. It can be used for a variety of sewing projects, including home decor, upholstery, and more. Core spun thread is also suitable for garments, including synthetic and stretchy fabrics. However, when choosing a core spun thread, it is essential to consider the fabric type.
Core spun sewing thread is produced using a number of spinning systems. Conventional ring spinning is an economical method, but the core needs to be positioned accurately in the centre of the ring. This process has many drawbacks, such as the risk of strip back, which can lead to broken thread. The Dref III method is also capable of precise core positioning. It can also be used to make industrial-grade threads.
A core spun sewing thread is similar to a regular thread, but it is constructed differently. It has a core, which is a continuous filament of yarn, and a sheath covering. The core provides the strength and durability, while the sheath adds drape and softness to the fabric. Its unique structure makes it ideal for garments and other applications that demand increased durability and comfort.
Core spun polyester sewing thread is a good option for high-speed sewing. This type of thread is also suitable for sewing garments that are firm or require more tensile strength. It is also available in a wide range of yarn counts and colors. And it has the look and feel of cotton. It can be used for any manufacturing need. So, when choosing a core spun sewing thread, be sure to consider all these features.
The strength of core spun yarns is directly related to the number of filaments in the core. Moreover, the number of active sheath fibres in a core spun thread depends on its mechanical and physical properties. The amount of sheath fibres in the thread affects its wrapping effectiveness. The wrap angle and the firmness of the wrap also affect the wrap effectiveness. The spinning parameters of a Dref III core spun sewing thread is directly proportional to the strength of the core filaments.
High-speed sewing generates a large amount of heat. This heat increases with the number of layers to be sewn. As a result, the needle temperature will rise if sewing at high speeds. At 5,000 stitches per minute, the needle temperature will increase significantly. Using a high-strength polyester filament that has a melting point between 255 and 260 deg C will prevent the thread from overheating.
