Factors affecting the tensile strength of fabrics include fiber material, fiber structure, fiber thickness, yarn weaving method, fabric density, etc.
1. Fiber material: Fibers of different materials have different tensile strengths. For example, natural fibers such as cotton and hemp have low strength, while synthetic fibers such as polyester and nylon have high strength.
2. Fiber structure: The structure of a fiber has a significant effect on its tensile strength. For example, polyester fibers have high tensile strength due to their linear structure, while cotton fibers have low tensile strength due to the large number of voids between the fibers.
3. Thickness of fiber: the thicker the fiber, the higher its tensile strength. This is because the thicker fibers have more interweaving points and can provide more support.
4. How the yarn is spun: The way the yarn is spun also affects the tensile strength of the fabric. For example, terry cloth is finely woven with fine yarns and has low tensile strength; while denim is rough-woven with thick yarns and has high tensile strength.
5. Density of the fabric: The higher the density of the fabric, the greater its tensile strength. This is because the fabric yarns with high density have more interweaving points, and the effect of supporting each other is better.
These factors also have a certain influence on the overall quality of the fabric. Fabrics with high tensile strength are less likely to be deformed and damaged, and have better durability and service life. Fabrics with low tensile strength are easily deformed and damaged by external forces, and have a shorter service life. Therefore, when choosing a fabric, it is necessary to consider the tensile strength of the fabric according to specific needs.
