Analysis of influencing factors of leather abrasion resistance1
When it comes to the use of leather products, now leather products are more and more popular with consumers. Then the wear resistance of leather is valued by manufacturers and consumers. So what is the main factor in the abrasion resistance of leather? How to improve the wear resistance of leather? The following editor will analyze it for you as follows. The abrasion resistance of leather refers to the resistance to abrasion of leather, which is expressed by the inverse of the abrasion rate or degree of abrasion under specified friction conditions. The main factors affecting the abrasion resistance of leather: There are many factors that affect the abrasion resistance of leather, such as: mechanical properties of fibers, shape and size of fibers, experimental conditions and leather craftsmanship and so on. The mechanical properties of fibers and the influence of shape and size include ① the effect of fiber mechanical properties. The relative importance of fiber tensile, bending and shear properties to leather wear resistance varies according to the difference in structure and use conditions; ② fiber morphology The effect of size. The important conditions that affect the leather wear test data are ① the influence of abrasives; ② the influence of tension and pressure; ③ the influence of temperature and humidity. There is also life in the actual use process. Due to the effects of sunlight, sweat, humidity, etc. on the leather, the wear resistance of leather of the same specification in different environments is different. According to research, PU leather is more wear-resistant than PVC artificial leather, and it is not so easy to become hard and brittle. Especially the birth of a new type of green leather, the wear resistance of zero-solvent PU synthetic leather has surpassed the satisfaction of consumers and manufacturers. Whether it is used in car seat modification or leather sofa, its wear resistance is even more prominent. After long-term use, it still maintains the original feel and color.
