Description

Technical Field

[0001] The utility model relates to a composite insole made of industrial hemp warp-knitted weft-lined fabric, belonging to the technical field of insoles. Background Art

[0002] Hemp with a THC content below 0.3% is called industrial hemp, also known as hemp, thread hemp, cold hemp, or fire hemp. Hemp fiber is a natural fiber. Its fabrics are widely used in the textile industry for their excellent properties, such as cooling and breathable properties, static elimination, and natural antibacterial properties.

[0003] Insoles are typically made from a composite of foam and fabric. EVA or polyurethane foam is often used. While these materials offer a certain degree of elasticity and cushioning, providing cushioning during exercise, their tear resistance compromises comfort. The fabric used is typically polyester. While polyester offers excellent strength, wear resistance, and dimensional stability, it also suffers from low moisture absorption, resulting in slippage due to sweating, and poor antibacterial and odor-resistant properties.

[0004] How to combine foaming materials with industrial hemp to prepare an insole with good cushioning, shock absorption, moisture absorption, breathability and antibacterial effects has become a problem to be solved. Utility Model Content

[0005] The utility model aims to provide an industrial hemp warp-knitted weft-insulated fabric composite insole, which has good shock-absorbing and buffering effects and moisture-absorbing, breathable and antibacterial effects.

[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the foaming layer is EVA foaming material or TPU foaming material; the EVA foaming material is a plant fiber powder modified EVA composite foaming material.

[0012] On the basis of the above scheme and as a preferred scheme of the above scheme: a lining warp yarn that does not participate in loop formation is further arranged along the warp direction between the coils and the extension lines of the warp knitted fabric; the lining warp yarn is industrial hemp blended yarn.

[0013] On the basis of the above solution and as a preferred solution of the above solution: the surface of the foaming layer on the side away from the industrial hemp warp knitted weft inlay fabric layer is provided with anti-slip texture.

[0014] On the basis of the above solution and as a preferred solution of the above solution: the surface of the foaming layer on one side close to the industrial hemp warp-knitted weft-inserted fabric layer is compounded with a loofah layer through a second adhesive layer.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] Combine Figure 1 and Figure 2 The present embodiment is described in detail. The present embodiment relates to an industrial hemp warp knitted weft inlay composite insole, comprising a foaming layer 1 and an industrial hemp warp knitted weft inlay fabric layer 3 bonded together by a first adhesive layer 2 .

[0025] Furthermore, the foaming layer 1 is an EVA foam material or a TPU foam material. In this embodiment, EVA foam material is selected, and the specific EVA foam material is a plant fiber powder modified EVA composite foam material. The plant fiber powder used is industrial hemp fiber powder with a particle size of 1-100 microns. Specifically, the plant fiber powder is first modified with a silane coupling agent to obtain a modified plant fiber powder; the ethylene-vinyl acetate copolymer and the modified plant fiber powder are mixed and kneaded; the ethylene-vinyl acetate copolymer and the modified plant fiber powder are mixed and kneaded, and a thin sheet is made; a release agent is sprayed on the mold of the foaming machine, and the thin sheet is added to the mold for molded foaming to obtain the plant fiber powder modified EVA composite foam material.

[0026] Because warp knitted fabrics utilize an interlocking coil structure, they are subject to significant deformation, resulting in insufficient dimensional stability. By adding warp, weft, or diagonal yarns to a warp knitted fabric, a warp knitted fabric with enhanced dimensional stability can be obtained. The industrial hemp warp knitted weft inlay fabric 3 comprises a warp knitted fabric 31, wherein weft inlay yarns 32, which do not participate in loop formation, are arranged along the weft direction between the coils and the extension lines of the warp knitted fabric 31; the weft inlay yarns 32 are industrial hemp blended yarns. The industrial hemp blended yarns used, namely hemp blended yarns, utilize the excellent properties of industrial hemp fiber, such as good hygroscopicity and natural antibacterial properties.

[0027] Furthermore, the warp knitted fabric 31 is woven from ramie fiber yarn, flax fiber yarn, industrial hemp fiber yarn, bamboo fiber yarn, antibacterial cotton yarn, polyester filament or nylon 6 filament. In this embodiment, antibacterial cotton yarn can be selected, which has good hygroscopicity and antibacterial properties.

[0028] Furthermore, the first adhesive layer 2 is made of cellulose powder polyurethane adhesive, and of course, ordinary polyurethane adhesive can also be selected.

[0029] Furthermore, the foam layer is provided with an array of ventilation holes. In this embodiment, the first adhesive layer 2 also has ventilation holes. The adhesive can be arranged in a dotted, linear, or mesh pattern to provide a breathable effect. Similarly, it can be perforated together with the foam layer 1 to provide a breathable effect.

[0030] Example 2

[0031] Combine Figure 3 and Figure 4 This embodiment is described in detail. This embodiment, involving an industrial hemp warp-knitted weft-inserted composite insole, differs from the first embodiment in that non-loop-forming warp yarns 33 are interspersed along the warp direction between the loops and the extension lines of the warp-knitted fabric 31. These insulated warp yarns 33 are industrial hemp blended yarns. The use of insulated warp yarns 33 and weft yarns 32 ensures that the industrial hemp warp-knitted weft-inserted fabric layer 3 exhibits excellent dimensional stability in both the warp and weft directions.

[0032] Another difference from the first embodiment is that the surface of the foaming layer 1 on the side away from the industrial hemp warp-knitted weft-inserted fabric layer 3 is provided with anti-slip textures.

[0033] The third difference from the first embodiment is that the surface of the foaming layer 1 on one side close to the industrial hemp warp-knitted weft-inserted fabric layer 3 is compounded with a loofah layer 5 through a second adhesive layer 4 .

[0034] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
