Problems solved by technology

[0002] At present, all kinds of shoes on the market are provided with soles and uppers connected to the soles. Wherein, the materials of the uppers are mostly made of cloth, leather, plastic, foam and other materials, but most of the existing shoe uppers are There are the following deficiencies: 1. Poor air permeability, which easily causes feet to sweat and produce odor; 2. Poor comfort, and the contact feeling with feet still needs to be strengthened; 3. Poor elasticity; 4. Cannot achieve the effect of warm in winter and cool in summer; 5. Not durable, easy to deform

preparation example Construction

[0032] The preparation method of latex shoe upper comprises the following steps:

[0033] (1) Prepare foam latex layer:

[0034] Put 60-75% of natural latex, 20-35% of styrene-butadiene rubber and 3-8% of additives into the mixing equipment in proportion to mix, stir well, and put the well-stirred latex mixture into the foaming equipment Foaming in the medium, then pour the foamed latex mixture onto the conveyor belt, and adjust the thickness of the latex mixture, then transport it to the oven for drying, add sulfur and vulcanize, and obtain the preset thickness after the second adjustment of the thickness Sheet foam latex layer;

[0035] (2) Upper molding:

[0036] The foamed latex layer is placed between the outer fabric layer and the inner fabric layer, and the foamed latex layer, the outer fabric layer and the inner fabric layer are hot-pressed and connected together by a hot pressing device to form a latex shoe upper.

[0037] Wherein, the drying temperature may prefer...

Abstract

The invention discloses a latex vamp, a shoe and a preparation method thereof. The latex vamp comprises an outer fabric layer, a foaming latex layer and an inner fabric layer, the foaming latex layeris connected between the outer fabric layer and the inner fabric layer, and the foaming latex layer is formed by foaming the following raw materials: 60-75% of natural latex; 20-35% of butadiene-styrene rubber; and 3-8% of an assistant. The natural latex is adopted in the invention, and has good breathability, sweat absorption performance, high perspiration property, foot sweating difficulty, thelatex vamp has the advantages that the latex vamp is odor-resistant, mildew-proof, antibacterial, good in comfort, good in contact with a foot, good in elasticity, durable, free of looseness and deformation, washable, warm in winter and cool in summer, physical property detection can meet an European Union standard, and the foamed latex layer is made by adopting a unique formula and process, so that the latex vamp can be sewn and sewn and is not easy to damage and long in service life.
