Nylon is a synthetic fiber with reliable physical and chemical properties. Nylon twisted sewing thread, also known as high-strength polyester twisted yarn, is a common yarn made by twisting technology in the textile industry.
In the production process of nylon sewing thread, the twisting technology can make the yarn easily twisted 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.
Process principle of nylon twisted yarn
Nylon twisted yarn is a yarn made by twisting two or more yarns at the same time, even the original single yarn can become a twisted yarn. 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.
The process of nylon twisted yarn is usually divided into two steps: the first step is forming twisting, that is, twisting multiple single yarns into one strand through a forming machine, and the second step is whole strand twisting, that is, twisting the already formed yarn into a strand again to shorten it and enhance its strength. In the process of forming twisting, it can be divided into two methods: 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 characteristics of nylon twisted sewing thread
- Characteristic 1: higher strength, wear resistance, corrosion resistance, and aging resistance;
- Characteristic 2: better elasticity, more tensile resistance, and more twist resistance;
- Characteristic 3: pure composition, less impurities, and stable color.
Conclusion
Due to its reliable physical and chemical properties, nylon twisted yarn is widely used in a variety of textiles, among which fishing lines, ribbons, bras, swimwear, socks, driving belts and other fields are widely used.
