The most important characteristic of leather is firmness. In order to let everyone know something about the fastness performance of leather, the following is an explanation for everyone, which is divided into the following types :(1) Bending Strength: refers to the number of times the leather is bent when its surface is damaged due to repeated bending. The height of this indicator, for some leather products (Such as leather shoes)The wearing life has a great influence. For example, the bending resistance of yellow cattle soft upper leather is dozens of times higher than that of yellow cattle modified upper leather. The bending resistance of the former is much higher than that of the latter, and it is not easy to be broken during use. (2) Cracking strength: refers to the leather being jacked up to make it inside (Surface) The load force per unit area when cracks occur. This strength index mainly reflects the processability of leather, but it is not very important in actual wear. (3) Tensile strength: refers to the maximum tensile load force that the leather unit can bear. This index is one of the important indexes of surface leather fastness. In other words, the tensile strength is the strength of the leather. (4) Bending Strength: refers to the number of times the leather is bent when its surface is damaged due to repeated bending. The height of this indicator, for some leather products (Such as leather shoes)The wearing life has a great influence. For example, the bending resistance of yellow cattle soft upper leather is dozens of times higher than that of yellow cattle modified upper leather. The bending resistance of the former is much higher than that of the latter, and it is not easy to be broken during use. (5) Tear strength: refers to the maximum load force that the leather can bear to continue tearing per unit thickness. It mainly shows the size of the external tension that the pinhole can bear after the leather is stitched. Therefore, if the tear strength of leather is too low, it is easy to tear from pinholes or other places with openings.
