Problems solved by technology

The main disadvantages of this product are low water pressure resistance, poor waterproof performance, and no anti-mildew and anti-bacterial properties
This is a large performance limitation for PTFE film composite fabrics mainly used in outdoor multi-purpose shoes

Embodiment Construction

[0019] In one embodiment of the present invention, the process steps of making shoe fabrics are:

[0020] a) Pass the warp-knitted cotton cloth through an aqueous solution containing 1.5% nano-silver anti-mold and antibacterial agent, dry it at 200° C., and wind it up after moisture absorption and perspiration and shaping pulp edge treatment to obtain a good anti-mold and antibacterial warp-knitted cotton cloth ;

[0021] b) Add 2% nano-silver anti-mold and antibacterial agent and appropriate amount of lubricant to the polytetrafluoroethylene micropowder, sieve after mixing, mature, compact, push, extrude, calender (base band), and base band longitudinal stretching (degreasing), transverse stretching (expansion) steps, obtain polytetrafluoroethylene film; The double-sided coating of polytetrafluoroethylene film contains the polyurethane adhesive of 5% anionic surfactant and 12% blowing agent, and consumption is 50g / m 2 , after drying at 140-150°C, wind up to obtain an antiba...

Abstract

The invention relates to breathable composite vamp material with functions of resisting mildew, bacteria and water and a method for preparing the vamp material. The vamp material comprises an outer synthetic fiber plain cloth layer, a medium polytetrafluoroethylene film layer with urethane foam coatings on both faces and an inner conventional tricot layer, wherein the tricot layer, the polytetrafluoroethylene film layer and the fiber plain cloth layer all contain inorganic nano mildew-proof antibacterial agent. The method for preparing the vamp material primarily comprises the mildew-proof antibacterial treatment of the inner and the outer layers, the preparation of the mildew-proof antibacterial polytetrafluoroethylene film and the binding of all the layers. Because the vamp material contains the inorganic nano mildew-proof antibacterial agent, the vamp material can inhibit the growing of fungi and bacteria, thereby better protecting foot heath, and keeping good water-proof permeability. Both faces of the polytetrafluoroethylene film are provided with the special urethane coatings, therefore the functions of resisting water and folding are obviously improved, and peeling resistance between layers is increased.

Description

technical field [0001] The invention belongs to the field of fabrics, and in particular relates to a waterproof and breathable composite shoe fabric with mildew-proof and antibacterial properties and a manufacturing method thereof. Background technique [0002] Traditional footwear is mainly made of natural fabrics, which are comfortable to wear and have good air permeability, but the main disadvantages are that they are not wear-resistant and have no waterproof ability. With the continuous advancement of technology and the continuous improvement of people's requirements for product performance, natural fabric footwear is no longer in a dominant position, and products with waterproof capabilities have begun to appear. However, most of these products adopt a rubber film directly pasted on the outside of the fiber fabric. Although it is waterproof, it is not breathable, and it is very stuffy during wearing. In recent years, footwear made of waterproof and breathable composite...
