Problems solved by technology

At present, most of the canvas shoes on the market have thin soles, are easily soaked in water, have poor waterproof performance, and the wear resistance and air permeability need to be further improved.
In addition, the design of the upper of the canvas shoes also has problems such as the inability to waterproof and dehumidify, so that when the canvas shoes are worn on rainy days, the rain can easily soak the upper and enter the inside of the shoe cavity, resulting in dampness inside the shoe body and poor wearing experience

Abstract

The invention discloses a canvas shoe with a double-layer waterproof sole. The canvas shoe comprise a sole, a vamp is arranged at the top of the sole, and the bottom end of the vamp is connected with the joint of the sole; the sole is a double-layer composite sole and comprises an upper-layer sole and a lower-layer sole, the outer side of the double-layer composite sole is coated with wear-resistant waterproof glue, and the end face of the upper-layer sole is combined with a breathable antibacterial fiber net; the vamp is made of a double-layer vamp fabric and comprises an antibacterial breathable layer and a waterproof layer; and the upper surface of the antibacterial breathable layer and the waterproof layer are in hot-pressing composite connection through a polyurethane hot melt adhesive. According to the double-layer waterproof sole, a reasonable raw material formula is adopted, the optimal and most reasonable raw material formula is screened and adjusted through tests, and finally the double-layer sole has high strength, high wear resistance, high stability, high elasticity and excellent waterproof property, antibacterial property and breathable property. In addition, the vamp fabric prepared by the invention has excellent waterproof property while having air tightness and water tightness.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to canvas shoes with double-layer waterproof soles.
