Specific wear resistance of technical fabrics and leather

Compare your skin with plastic (clothing material), which one has better wear resistance?

Fastness is an important symbol of the inherent quality of leather. The fastness of leather is divided into the following categories.

1. tensile strength: refers to the maximum tensile load that leather can bear per unit cross section. This is one of the important indexes to judge the fastness of upper leather. In other words, the tensile strength is the solid strength of leather.

2. Tearing strength: refers to the maximum load force that can be borne by further tearing of leather per unit thickness. It is mainly manifested in the magnitude of the external tension that the leather can bear at the pinhole after sewing. So if the tearing strength of leather is too low, it is easy to tear from pinholes or other places with mouths.

3. Crack strength: refers to the load force per unit area when the leather is jacked up and cracked inside (surface). This strength index mainly reflects the processing performance of leather, which is not very important when actually worn.

4. Bending strength: refers to the number of times the leather surface is damaged due to repeated bending. The level of this index has a great influence on the wearing life of some leather products (such as leather shoes). For example, the bending strength of cattle soft upper leather is several times higher than that of cattle modified upper leather, which is mainly because the bending strength of the former is much higher than that of the latter, so it is not easy to be damaged during use.
