The tensile strength of yarn is one of the important indicators of yarn. There are many factors affecting the tensile strength of yarn. During the production process, it is necessary to pay attention to the regulation and control of these influencing factors.
What are some factors that can affect the tensile strength of yarn?
1. Type and quality of fiber: The type and quality of fiber directly affect the tensile strength of yarn. In general, the thinner and longer the fibers, the higher the tensile strength of the yarn.
2. The twist of the yarn: the higher the twist of the yarn, the higher the tensile strength. But too high twist will also reduce the softness and bendability of the yarn, so a balance needs to be made between twist and softness.
3. Yarn density: The higher the yarn density, the higher the tensile strength. But too high a density will also lead to a decrease in the softness of the yarn.
4. Yarn processing technology: The processing technology of yarn will also affect its tensile strength. For example, stretching and heat treatment of yarn can increase its tensile strength.
5. Humidity of the yarn: The humidity of the yarn will also affect its tensile strength. In general, yarns have a higher tensile strength in a dry environment than in a wet environment.
The above are some common factors that affect the tensile strength of yarn.
