Tensile breaking properties and wear resistance of fabrics
The tensile breaking properties of knitted fabrics include satin strength and elongation at break. The basic principle of testing is to use a suitable mechanical method to gradually increase the tensile force on the sample until it breaks within the specified time limit, and the breaking strength and breaking elongation are recorded by the instrument. This method is not suitable for knitted fabrics and lace with relatively high elasticity.
The Martindale method is usually used to test the wear resistance of knitted fabrics. The principle is: the circular sample and the standard abrasive are worn together under a certain pressure according to the casual trajectory of the pear into the curve, causing the sample to be damaged until a hole is worn out.
According to the dressing concept of modern consumers, work clothes are often eliminated not because of damage (stretch breakage or fraying), but are updated with the popularity of colors and changes in styles, especially Emphasizing the comfort, health and environmental protection of clothing, knitted fabrics generally used as work clothes meet the requirements of strength and wear resistance. Therefore, in the wearing performance test of modern fabrics, tensile breaking properties and wear resistance are generally omitted Testing in other aspects is only carried out when it is really necessary to test new processes and new products.
