Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of insole preparation, in particular to an ultra-light insole preparation device and process. BACKGROUND

[0002] An insole is a component used in the shoe for the direct contact between the upper surface of the insole and the sole of the foot. The basic function of the insole is to provide comfort to the sole of the shoe. Common materials include silicone, PU, and EVA. Some insoles are also made of multiple layers of fabric to improve comfort. The resilience of the insole is an important indicator. High resilience insoles can reduce foot pressure to some extent and provide pressure relief. In addition, as consumers increasingly value health, more and more consumers consider the health benefits of insoles. The health benefits of insoles include their antibacterial properties. Since the feet are enclosed in shoes for a long time, fungal growth can occur if foot sweat is not promptly evaporated and expelled from the body, leading to problems such as athlete's foot and foot odor. The insole is in direct contact with the foot, and its good antibacterial properties can effectively alleviate these problems. On the other hand, when the weather is hot or the amount of exercise is large, the temperature inside the shoe is high, and the feet can easily feel stuffy. Conversely, when the weather is cold and there is no exercise for a long time, the temperature inside the shoe is low, and the feet can easily feel cold, which greatly reduces the comfort of consumers.

[0003] In the Chinese invention patent with application number CN202111137946.9, a high-resilience ultra-light insole and its preparation method are proposed. The fabric layer adopts a pit strip concave-convex structure, in which the strip-shaped protruding part is woven with anti-fouling yarn, providing good anti-fouling effect, reducing the cleaning frequency of the wearer, providing convenience for the wearer, and prolonging the service life and functional period of the insole. The strip-shaped recessed part is woven with temperature-regulating fiber, providing good temperature-regulating effect. The polyurethane layer of the insole has good resilience and is prepared using a supercritical method, resulting in low density and light weight, which can further reduce the overall weight of the shoe and improve the comfort of the shoe. During wear, the strip-shaped protruding part of the fabric layer is in contact with the sole, and its anti-fouling effect prolongs the service life of the insole, reducing the difficulty and frequency of cleaning. The temperature-regulating fiber is cellulose fiber, which simultaneously provides temperature-regulating and water-absorbing effects. The overall strip effect, water-absorbing property, and anti-fouling property of the fabric layer are compatible through the concave-convex strip structure, improving the comfort of the insole. The temperature-regulating yarn microcapsule wall material of the fabric layer is chitosan, which has certain antibacterial effect, improving the health benefits of the insole. The adjustable protrusions and adjustable pipelines on the upper surface of the insole allow the internal flowing liquid to flow continuously with the human body, providing a massaging effect on the sole of the foot. The massaging method is water flow rolling, which can provide a soothing effect.

[0004] However, although the soles proposed in the aforementioned prior art are relatively lightweight and have a certain antibacterial effect, the antibacterial effect is not good enough, the duration of the antibacterial effect is not long enough, and the service life is limited, leaving room for improvement. Therefore, this application is hereby filed. Summary of the Invention
