The wear resistance of a fabric refers to its ability to resist wear and tear under repeated mechanical friction. Its wear resistance has a direct impact on the product's usage time and effectiveness.
1) Physical properties of fibers
The physical properties of fibers mainly manifest as their tensile, bending, and shear properties. The fabrics of textile products such as work, training clothes, and labor protection clothing can choose fibers with good tensile properties. During the wear process, the fibers are subjected to repeated stress. Fibers with high tensile properties do not affect their deformation ability after repeated stretching, and still have good wear resistance.
2) The morphology and size of fibers
The morphology and size of fibers also have an impact on the wear resistance of fabrics. For example, the length, thickness, and cross-sectional form of fibers.
Yarn spun from longer fibers has good mechanical properties such as strength, elongation, and fatigue resistance, thus possessing good wear resistance. Yarn spun from fibers with low fineness has good strength, elongation, and fatigue resistance, but fibers with low fineness are prone to damage when subjected to frictional forces.
So, when choosing fiber fineness, the first step should be to increase the fiber fineness while maintaining the tensile and shear strength that the fiber can withstand.
3) Geometric structure of fabric
The geometric structure of a fabric also has an impact on its wear resistance, mainly manifested in its thickness, warp and weft density, weight per unit area, apparent density, and feather content.
Generally speaking, the thicker the fabric, the higher the warp and weft density, the greater the weight per unit area, the higher the apparent density, and the higher the feather content, the better the wear resistance; On the contrary, the wear resistance is poor.
4) The dyeing and finishing process of fabrics
Some special dyeing and finishing processes can cause a decrease in fabric strength, such as high dye corrosiveness, durable and iron free finishing, or improper process operations such as excessive alkali reduction and excessive use of silicone oil. This can lead to intensified fiber degradation reactions and a decrease in fabric wear resistance and other mechanical properties under the combined effects of high temperature, catalysts, and acidic conditions.
Therefore, before various dyeing and finishing processes, small tests should be conducted in advance, and samples should be regularly cut during the processing to monitor the physical properties of the processed fabric. If the bulk production is completed, the tearing strength and bursting strength of the processed fabric can be improved by using a warp fastness enhancer (Z36) to reduce fabric damage and loss.
