Abstract

The invention relates to a genuine leather composite insole and a preparation method thereof, the genuine leather composite insole comprises a modified genuine leather layer and a modified thermoplastic elastomer layer, and the thickness ratio of the modified genuine leather layer to the modified thermoplastic elastomer layer is 1: 5; the preparation method comprises the following steps: S1, preparing fiber-nano support sol; s2, preparing modified leather and a modified thermoplastic elastomer; s3, putting the modified leather and the modified thermoplastic elastomer into a mold, closing the mold, demolding, and cooling to room temperature to obtain the leather composite insole. The prepared composite insole is good in moisture absorption effect, good in elasticity and high in tear strength.

Description

technical field [0001] The invention relates to the field of insole, in particular to a leather composite insole and a preparation method thereof. Background technique [0002] The whole sole piece made of animal leather, such as the sole piece made of cowhide, can make the shoe overall firm and expandable, shape long, breathable, comfortable to wear, not easily deformed, and has a beautiful appearance. It is commonly used in high-end shoes. raw material. However, the whole shoe sole made of animal leather is not only expensive, but also has poor moisture absorption, poor elasticity and average tear resistance. In particular, the supply of animal leather is difficult to meet the needs of the footwear industry. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the present invention is to provide a leather composite insole and a preparation method thereof. The obtained composite insole has good moisture absorption effect, good elasticity and high tear resis...
