Problems solved by technology

[0003] Existing composite insoles with functions such as deodorization include a surface layer and a bottom layer, and a foaming sponge layer or an activated carbon fiber layer with active carbon attached is provided between the surface layer and the bottom layer, but the foaming type sponge layer or the activated carbon fiber layer can The ratio of activated carbon adsorbed is small, and the deodorization ability is poor, so the deodorization effect of this composite insole is not good.
In addition, the manufacturing method of this kind of composite insole is generally: first absorb activated carbon on the foamed sponge layer or activated carbon fiber layer, then place the foamed sponge layer or activated carbon fiber layer between the surface layer and the bottom layer, and place The layers are stitched together, but the stitched structure between the layers is not stable enough, it is difficult to fix the activated carbon on the foam sponge layer or the activated carbon fiber layer between the surface layer and the bottom layer, and the activated carbon is easy to get stuck between the surface layer and the bottom layer. even through the insole

Embodiment 1

[0023] See Figure 1~2 , a composite insole, which comprises a surface layer 1, a non-woven fabric layer 4, an activated carbon interlayer 3, a fine cloth layer 5 and a bottom layer 2 from top to bottom, and the layers are bonded together by hot melt adhesive, wherein the activated carbon The granular activated carbon in the interlayer is bonded together by hot melt adhesive, wherein the non-woven fabric layer 4 can also be a knitted fabric layer or a woven fabric layer, etc., and the fine cloth layer 5 can also be a non-woven fabric layer, a knitted fabric layer or a woven fabric layer. layers etc. The activated carbon interlayer is prepared according to the volume ratio of 75% to 85% of granular activated carbon and 15% to 25% of hot melt adhesive, and the granular activated carbon is 20 mesh particles.

[0024] The surface layer 1 is a porous cloth layer or a leather layer, and the cloth layer or the leather layer has good air permeability, so that sweat and air can pass t...

Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is that the manufacturing method of the above-mentioned composite insole comprises the following steps:

[0033] A. Sprinkle a layer of 100-mesh hot melt adhesive powder on the non-woven fabric layer 4. After baking and heating in an oven at 250°C for 15 seconds, place the surface layer 1 on the side of the non-woven fabric layer 4 with hot melt adhesive At the same time, the surface layer 1 and the non-woven fabric layer 4 are quickly hot-pressed together by a pressure wheel at 120°C to obtain a surface composite layer, which is cooled to room temperature by a cooling wheel and rolled up for use;

[0034] B. Coat a layer of hot melt adhesive on the latex layer, then place the muslin layer 5 on the side of the latex layer coated with hot melt adhesive, and at the same time, the muslin layer and the latex layer are quickly baked and thermally bonded in an oven at 120°C together to make the bottom composite layer;

Abstract

The invention relates to the field of insole technology, particularly to a composite insole and a method for making same, which includes a surface coat and a bottom coat, an activated carbon interlining composed of granular activated carbons is provided between the surface coat and the bottom coat, and the layers are bonded to each other with bonding agent, wherein, the granular activated carbons in the activated carbon interlining are bonded together through adhesion agent which has good caking ability and provides firm bonding, and more activated carbons can be bonded, off-flavor removing capability of the adhesion agent is strong, and the activated carbon interlining can absorb static generated by human body friction, which ensures health of users; therefore, the composite insole composed of a plurality of layers of the invention has functions of deodorization, mould proofing, bacteriostasis, sweat-absorbing, air permeability, cushioning, strong elasticity and static resistance.

Description

Technical field: [0001] The invention relates to the technical field of insoles, in particular to a composite insole and a manufacturing method thereof. Background technique: [0002] Insoles are widely used as one of the indispensable articles for people's life. With the improvement of people's living standards, traditional handmade insoles have been difficult to meet the needs. Instead, all kinds of insoles produced from the assembly line are incomparable to traditional insoles in terms of appearance, function, comfort and price. Therefore, it is becoming more and more popular. A variety of insole raw materials with unique functions have been developed and used in the production of insoles to meet people's different needs from different aspects, such as deodorization, mildew resistance, antibacterial, sweat absorption, shock absorption, elasticity, antistatic, magnetic and other functions . [0003] Existing composite insoles with functions such as deodorization include...
