The mechanical properties of fabrics include tensile strength and breaking strength. Tensile strength refers to the fabric's ability to withstand maximum tensile force during stretching, while breaking strength is the stress value at which the fabric breaks. These indicators reflect the fabric's durability and load-bearing capacity. High-strength fabrics are suitable for making outerwear, work clothes, and outdoor gear, while low-strength fabrics are suitable for lightweight clothing or decorative purposes. Tear strength and abrasion resistance are also included. Tear strength indicates the fabric's resistance to tearing under localized stress, while abrasion resistance measures the fabric's ability to maintain surface integrity under frictional conditions. Fabrics with high tear strength and abrasion resistance are more suitable for long-term wear or high-frequency use scenarios, such as uniforms, sportswear, and workwear. Weaving method, yarn thickness, and density have a significant impact on these properties.
Fabrics also possess elasticity and resilience. Elasticity is the fabric's ability to stretch after being deformed under stress, while resilience refers to the fabric's ability to return to its original shape after being stressed. Knitted fabrics generally have better elasticity, while woven fabrics have lower elasticity. Good elasticity and resilience not only ensure wearing comfort but also prevent garment deformation, wrinkles, or sagging, improving lifespan and aesthetics.
