Description

[Technical field]

[0001] The present invention relates to the technical field of cork fabric materials, and more particularly to composite products using cork fabric materials. [Background technology]

[0002] Cork fabric is a material made from natural cork material, which is relatively light, easy to process and transport, has good breathability, and can effectively regulate humidity. The structure of cork gives it waterproof properties, and cork can effectively absorb sound, making it suitable for environments where noise reduction is required, and cork fabric has a tough surface, is wear-resistant, and has a long service life. Cork material is made from renewable trees, and its production process has little impact on the environment. The softness and elasticity of cork make it comfortable to the touch when used in contact with the skin, making it suitable for clothing and household products. Cork has natural antibacterial properties, which can inhibit the growth of bacteria and keep it clean. The grain and color of cork fabric give it a unique visual aesthetic, making it suitable for various design styles. Cork has good insulation properties, making it suitable for heat preservation and insulation materials.

[0003] Cork fabric itself has functional properties such as heat insulation, softness, hydrophobicity, fire resistance, and elasticity, so it is widely used in waterproofing and heat insulation fields. However, the cork fabric material itself has low strength and is easily torn, so it cannot be used alone. Summary of the Invention [Problem to be solved by the invention]

[0004] Therefore, in order to solve the problem that cork fabric material itself has low strength and is easily torn, and therefore cannot be used alone, the present invention provides a composite product using cork fabric material. [Means for solving the problem]

[0005] The present invention is realized as follows. The present invention provides a composite product using cork fabric material, comprising a functional layer, a reinforcing base fabric, an elastic layer and a base layer, which are laminated in sequence, the functional layer and the reinforcing base fabric, the reinforcing base fabric and the elastic layer, and the elastic layer and the base layer are fixed and connected with adhesive layers, and the entire assembly consisting of the functional layer, the reinforcing base fabric, the elastic layer and the base layer are fixed by sewing all around.

[0006] Based on the above technical solutions, the composite product using the cork fabric material of the present invention may be further improved as follows: However, the functional layer is a cork fabric material, which is placed on top of the composite product for thermal insulation.

[0007] Furthermore, the sum of the thicknesses of the functional layer and the reinforcing base fabric is 0.3 mm, and the thickness of the reinforcing base fabric is greater than the thickness of the functional layer.

[0008] Furthermore, the elastic layer has a thickness of 3 to 20 mm, and the base layer has a thickness of 1 mm.

[0009] Furthermore, the entire assembly consisting of the functional layer, the reinforcing base fabric, the elastic layer and the base layer is fixed by piping or overlocking.

[0010] The beneficial effects of using the above-mentioned improved forms are as follows: the functional layer is made of cork fabric material, whose natural heat insulating properties can effectively prevent heat dissipation, improve the comfort during use, and can bring the user a warm touch; the whole is fixed by piping or overlocking techniques to ensure the tight bonding of each layer and the neat appearance, improve the durability of the product, and extend its service life.

[0011] Furthermore, the adhesive layers between the functional layer and the reinforcing base fabric, between the reinforcing base fabric and the elastic layer, and between the elastic layer and the undercoat layer are made of a vinyl acetate-ethylene copolymer emulsion.

[0012] The beneficial effects of using the above improvements are as follows: The adhesive layers between the functional layer and the reinforcing base fabric, between the elastic layer and the base layer ensure a robust connection of each layer, preventing delamination and improving the integrity and durability of the entire structure.

[0013] Furthermore, the reinforcing base fabric is made of one or more of a PU film or a knitted or woven fabric, and is used to increase the strength of the functional layer.

[0014] Furthermore, the elastic layer is a filling material having elasticity and thickness.

[0015] The beneficial effects of using the above refinements are as follows: The elastic layer provides the product with cushioning and support functions, which can effectively absorb shocks during use and improve comfort and flexibility.

[0016] Furthermore, the base layer is an anti-slip material, and the bottom is provided with friction protrusions to increase the friction force of the bottom of the base layer.

[0017] The beneficial effects of using the above refinements are as follows: The base layer increases the friction force with the ground, ensuring that the product is stable and non-slip during use, improving safety.

[0018] Furthermore, the functional layer is made of Quercus serrata bark. Effect of the Invention

[0019] Compared with the prior art, the composite product using cork fabric material provided by the present invention has the following beneficial effects: The functional layer is generally made of cork fabric material produced from the bark of the Quercus serrata. It is mainly used for heat insulation and warmth, and has excellent heat insulation properties, effectively blocking the influence of external temperature and keeping the internal temperature of the product stable. The natural material properties of this layer give it good breathability and comfort, making it suitable for products that come into direct contact with the body.

[0020] The reinforcing base fabric is made of PU film or knitted or woven fabric, which enhances the strength of the whole structure. The thickness of the reinforcing base fabric is greater than that of the functional layer (0.3mm), and its main role is to improve the durability and tear resistance of the composite product, and ensure that it is not easily damaged during use. It also provides support for the functional layer and keeps the overall shape stable.

[0021] The thickness of the elastic layer is 3~20mm and can be adjusted according to specific needs. It is composed of elastic and thick filling material, which is mainly used to provide cushioning effect for comfort, improve the softness and conformity of the product, better fit the curves of the human body, and improve the user experience.

[0022] The base layer is a non-slip material, and the bottom is equipped with friction protrusions to increase the friction of the bottom, ensuring non-slip during use and improving safety. In addition, the thickness of 1mm ensures the stability and wear resistance of the product, extending its service life.

[0023] The functional layer, reinforcing base fabric, elastic layer and base layer are secured together by a vinyl acetate-ethylene copolymer emulsion adhesive layer, ensuring a robust connection between each layer and improving the stability and durability of the entire structure.

[0024] By fixing the entire product using methods such as piping and overlocking, the wear resistance of the edges of the product is improved and peeling between layers is prevented. [Brief description of the drawings]

[0028] Hereinafter, the technical solutions in the embodiments of the present invention will be clearly and completely described in combination with the drawings of the embodiments of the present invention, so as to make the objectives, technical solutions and advantages of the embodiments of the present invention more clear.

[0029] 1 shows an embodiment of a composite product using the cork fabric material provided by the present invention. This embodiment includes a functional layer 10, a reinforcing base fabric 20, an elastic layer 30, and a base layer 40, which are laminated in order, and the functional layer 10 and the reinforcing base fabric 20, the reinforcing base fabric 20 and the elastic layer 30, and the elastic layer 30 and the base layer 40 are fixed and connected with adhesive layers, and the whole consisting of the functional layer 10, the reinforcing base fabric 20, the elastic layer 30, and the base layer 40 is fixed by sewing around all four sides.

[0030] However, in the above technical solution, the functional layer 10 is a cork fabric material, which is placed on the top of the composite product for thermal insulation.

[0031] Furthermore, in the above technical solution, the sum of the thicknesses of the functional layer 10 and the reinforcing base fabric 20 is 0.3 mm, and the thickness of the reinforcing base fabric 20 is greater than the thickness of the functional layer 10 .

[0032] Furthermore, in the above technical solution, the thickness of the elastic layer 30 is 3-20 mm, and the thickness of the underlayer 40 is 1 mm.

[0033] Furthermore, in the above technical solution, the entire structure consisting of the functional layer 10, the reinforcing base fabric 20, the elastic layer 30 and the undercoat layer 40 is fixed by piping or overlocking.

[0034] Furthermore, in the above technical solution, the adhesive layers between the functional layer 10 and the reinforcing base fabric 20, between the reinforcing base fabric 20 and the elastic layer 30, and between the elastic layer 30 and the undercoat layer 40 are vinyl acetate-ethylene copolymer emulsions.

[0035] The main components of vinyl acetate-ethylene copolymer emulsions include vinyl acetate, ethylene monomer, and other additives such as emulsifiers and initiators.

[0036] Furthermore, in the above technical solution, the reinforcing base fabric 20 is made of one or more of PU film or knitted or woven fabric, and is used to enhance the strength of the functional layer 10 .

[0037] Furthermore, in the above technical solution, the elastic layer 30 is a filling material having elasticity and thickness.

[0038] The filling material, which has elasticity and thickness, is a sponge.

[0039] Moreover, in the above technical solution, the base layer 40 is an anti-slip material, and the bottom is provided with friction protrusions to increase the friction force of the bottom of the base layer 40.

The whole is stitched using piping or overlocking techniques to ensure a solid connection between layers and avoid falling off or abrasion, and the adhesive layer is allowed to fully cure under appropriate temperature and humidity, typically 24 hours, and upon completion, a thorough inspection is carried out to ensure that all layers are firmly connected and the product appearance is neat.
