High-toughness anti-cracking insole

Abstract

The invention discloses a high-toughness anti-cracking insole which is doped with a polyamide fiber material, and due to the fact that polyamide fibers are added in the mixing process of the insole, the polyamide fibers are high in strength, large in elongation, good in elasticity and excellent in abrasion resistance and heat resistance, the toughness of the insole is greatly improved, due to the elasticity of the polyamide fibers, the shoes are more comfortable to wear, and high toughness and comfort can be achieved while the cushioning effect is achieved so as to adapt to high-strength exercises.

Description

technical field

[0001] The invention belongs to the technical field of shoe processing, and in particular relates to a high-toughness anti-crack midsole and a preparation method thereof. Background technique

[0002] Shoes are the necessities of people's life, they can keep warm and protect the feet. However, the sole is very important for shoes. The structure of the sole is quite complicated. Material. The midsole of the shoe is the interlayer part between the sole and the shoe body. The thickness is generally about 1-2cm, which is used to buffer the vibration of the ground. The midsole of sneakers is the core part of cushioning technology. Scientific research has proved that the impact of the ground on the body during running is 8 times that of walking. Therefore, the performance of a pair of sneakers depends on the quality of the midsole. If there is no midsole, the vibration and friction generated during running or other sports will continue to damage the body, especia...
