Nylon is a synthetic fiber with reliable physical and chemical properties, which can be used to manufacture various industrial products. Nylon twisted yarn, also known as high-strength polyester twisted yarn, is a common twisted yarn technology in the textile industry.
In the nylon production process, the twisting technology can easily twist the yarn together to form a thicker thread and enhance its strength and elasticity. The purpose of twisting is to increase the strength and elasticity of the yarn and improve the resistance of the yarn to deformation forms such as stretching, twisting, and deformation.
Two Steps In The Twisting Process Of Nylon sewing Thread
The first step is forming twisting, that is, twisting multiple single yarns into one strand through a forming machine;
The second step is whole strand twisting, that is, twisting the already formed yarn again into a strand to shorten it and enhance its strength. In the process of forming twisting of nylon sewing thread, it can be divided into two ways: unidirectional twisting and bidirectional twisting. Unidirectional twisting refers to twisting in the same direction on the forming machine; bidirectional twisting is twisting in opposite directions.
Three Major Functions Of Nylon Twisted Thread
- Increase the strength and friction resistance of silk thread to reduce fuzzing and breakage, and improve the fastness of silk fabric.
- Give the silk thread a certain shape and color, and give the fabric appearance with refraction, wrinkles, loops and other effects.
- Increase the elasticity of silk thread, improve the wrinkle resistance and breathability of fabric (strong twist fabric), and make the fabric cool and comfortable to wear.
Conclusion
Nylon thread is a fiber with good wear resistance, good elasticity, good chemical resistance and good heat resistance. It can be used to make various textiles, such as fabrics, stockings, decorations, etc
