High-resilience ultralight insole and preparation method thereof

Abstract

The invention relates to the technical field of shoe materials, in particular to a high-resilience ultralight insole and a preparation method thereof. The insole comprises a fabric layer and a polyurethane layer, the upper surface of the fabric layer is of a concave-convex strip-shaped structure and comprises strip-shaped protruding parts and strip-shaped concave parts, the strip-shaped protruding parts and the strip-shaped concave parts are circularly arranged at intervals, the strip-shaped protruding parts are formed by weaving anti-fouling yarn, the width of each strip-shaped protruding part ranges from 0.5 mm to 1.5 mm, and the total area of the strip-shaped protruding parts does not exceed 30% of the area of the fabric layer. The strip-shaped concave parts are formed by weaving temperature adjusting yarns, and the width range of each strip-shaped concave part is 0.8-2mm; the polyurethane layer is prepared by a supercritical method, and the density of the polyurethane layer is 0.03-0.05 g / m < 2 >; the fabric layer and the polyurethane layer are compounded through dotted glue. The insole has a good antifouling effect and a good temperature adjusting effect, is prepared by adopting a supercritical method, and is low in density, light in weight and good in comfort.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to a high-resilience ultra-light insole and a preparation method thereof. Background technique [0002] The insole is used above the sole of the shoe and is in direct contact with the human body. The basic function of the insole is the comfort of the sole. The commonly used materials include silica gel, PU, ​​and EVA. Some insoles are also made of multi-layer fabrics. The role of comfort, the resilience of insoles is an important indicator, and insoles with high resilience will reduce the pressure on the feet to a certain extent and play a role in soothing pressure; in addition, as consumers continue to pay more attention to health Improvement, the health care of insoles is also considered by more and more consumers.

[0002] The insole is used above the sole of the shoe and is in direct contact with the human body. The basic function of the insole is the comfort of the sole. The commonly used materials include silica gel, PU, ​​and EVA. Some insoles are also made of multi-layer fabrics. The role of comfort, the resilience of insoles is an important indicator, and insoles with high resilience will reduce the pressure on the feet to a certain extent and play a role in soothing pressure; in addition, as consumers continue to pay more attention to health Improvement, the health care of insoles is also considered by more and more consumers. The health care of insoles includes its antibacterial properties. Since the feet are wrapped in shoes for a long time, when the sweat on the feet cannot be volatilized and excreted in time, fungi will grow and cause For problems such as athlete's foot and foot odor, the insole is in direct contact with the foot, and its good antibacterial type can effectively alleviate such problems; on the other hand, the foot is wrapped in the shoe for a long time. The temperature of the shoes is high, and the feet are prone to feel stuffy; on the contrary, when the weather is cold and there is no exercise for a long time, the temperature inside the shoes is low, and the feet are easy to be cold, which will greatly reduce the comfort of consumers.
