Description

Technical Field

[0001] The invention relates to the technical field of textile materials, and in particular to a multi-layer composite structure cooling composite product for preparing cooling products. Background Art

[0002] As people's living standards improve, the demand for comfort and functionality of textile products is gradually increasing. Especially in hot seasons, fabrics with cooling effects have received widespread attention. Currently, the cooling composite products available on the market are mainly achieved in the following ways:

[0003] Adding cooling materials: By adding cooling fibers or applying cooling coatings during the textile process, the fabric can produce a cooling effect when it comes into contact with the skin. However, the cooling effect of such cooling composite products is often affected by the ambient temperature and humidity, making it difficult to maintain a cool experience for a long time.

[0004] Moisture wicking structure: By using highly hygroscopic or fast-wicking fiber materials, the evaporation of sweat on the body surface is accelerated to achieve a cooling effect. However, this type of product mainly relies on the sweating process of the human body, its cooling effect is limited, and it has high requirements for breathability.

[0005] Multi-layer composite fabrics: Some cooling composite products adopt a multi-layer structure design, which combines functional membrane materials with textile layers to achieve cooling, waterproof or breathable functions. However, in the prior art, the functional superposition of multi-layer structures is limited, especially it is difficult to achieve waterproof, cooling and breathable effects at the same time.

[0006] Based on the above technical problems, the existing cool composite products still have a lot of room for improvement in air permeability, waterproofness and long-lasting coolness. Therefore, it is urgent to develop a composite structural fabric that can simultaneously possess coolness, waterproofness and air permeability to meet the needs of consumers in a variety of application scenarios. This fabric has a long-lasting cool effect and can be cleaned by hand washing or other gentle methods to maintain functional stability. In the prior art, cool composite products are prone to delamination, falling off and other problems during use due to insufficient bonding strength between different material layers, especially at the junction of the TPU film and the fabric or gel. Through the composite adhesive layer design provided by the present invention, a hot pressing or gluing process is adopted to successfully achieve high-strength bonding between materials, providing technical guarantee for the long-term use of composite fabrics; Summary of the invention

[0007] In order to solve the deficiencies of existing cool composite products in terms of air permeability, waterproofness and long-lasting cool performance, the present invention provides a cool composite product, which, through a multi-layer composite structure design, has good cooling effect, waterproofness and air permeability, and has high comfort and applicability.

[0008] The technical solution of a cool composite product of the present invention is as follows:

[0009] The fabric is composed of the following layers stacked in sequence: an upper composite adhesive layer and a middle gel layer. The overall thickness of the cool composite product is 0.5 mm to 1 cm.

[0010] Preferably, the composite adhesive layer includes a first fabric layer, a TPU film layer and a second fabric layer, and the three layers are combined by heat pressing or adhesive to form the composite adhesive layer.

[0011] Preferably, the characteristic material layer disposed on the other side of the gel layer may also be designed as a fabric penetration layer.

[0012] Preferably, a sealing layer is arranged on the other side of the characteristic material layer; the second fabric layer is arranged as an easily permeable fabric layer. The sealing layer is a TPU film layer, or it can be a waterproof surface, but the waterproof layer of the waterproof fabric is facing away from the gel layer.

[0013] Preferably, a fabric bottom layer is disposed on the other side of the sealing layer.

[0014] Preferably, the second fabric layer and the sealing layer are configured as permeable fabric layers.

[0015] Preferably, the thickness of the gel layer is 0.5 mm to 8 mm, and the water content of the gel is 20% to 50%.

[0016] Preferably, it is made into a pad with a thickness of 1 mm-1 cm.

[0017] An application of the cool composite product as claimed in the above claims, characterized in that it is made into clothing or bedding or eye masks or sleeves, and has a thickness of 0.5-5 mm.

[0018] A method for processing the cool composite product as described above comprises the following steps:

[0019] A. Superimpose the first fabric layer, the TPU film layer, and the second fabric layer, and combine them into a composite adhesive layer by hot pressing or gluing;

[0020] B. Uniformly coating the gel layer on the surface of the composite adhesive layer;

[0021] C. A characteristic material layer is arranged on the other side of the gel layer.

[0022] Preferably, in the processing of step A, a mold is set in advance according to the size of the fabric, and the composite adhesive layer is hot-pressed in the mold.

[0023] The fabric described above is suitable for making cooling pads, cooling clothing or other cooling products.

[0024] The number of layers of the product of the present invention can be set according to functional requirements, and the number of layers depends on the material of the characteristic material layer. If the characteristic material layer itself has functions such as waterproofing and sealing, five layers are sufficient. If the characteristic material layer is a soft material such as sponge, other functional layers can be added for sealing and waterproofing. The specific setting can be based on user needs.

[0025] The cool composite product provided by the present invention achieves the following technical effects through a specific multi-layer composite structure design:

[0026] Long-lasting cooling performance:

[0027] This fabric has a long-lasting cooling effect and can be washed by hand or other gentle methods to maintain its functional stability.

[0028] Combination of waterproof and breathable properties

[0029] The TPU film layer has excellent waterproof properties and can effectively block the penetration of external moisture. At the same time, its moisture permeability allows moisture to be discharged, avoiding the feeling of stuffiness and improving the overall comfort of the fabric.

[0030] Efficient fusion of composite structures

[0031] As the key intermediate layer, the TPU film layer effectively solves the problem of difficult compounding between the fabric layer and the gel layer, ensuring that each layer can be firmly combined during the compounding process to form a stable multi-layer structure.

[0032] Breathability and softness

[0033] The first fabric layer and the second fabric layer are made of textile fabric material, which is both breathable and soft, ensuring the comfort and skin-friendliness of the fabric when in contact with the skin, and is suitable for long-term wearing or use.

[0034] Structural stability and durability

[0035] Each layer is firmly bonded by heat pressing, adhesive or direct coating process. The overall structure of the fabric is stable and can withstand repeated use and cleaning, which improves the service life and market applicability of the product.

[0036] In step A, a specially designed mold is used to accurately position the first fabric layer, the TPU film layer, and the second fabric layer, and hot-press them together through the high temperature and high pressure function of the mold. The surface of the mold is coated with a high temperature resistant coating to prevent material adhesion, while providing uniform pressure distribution to make the composite adhesive layer more firmly bonded. The first fabric layer, the TPU film layer, and the second fabric layer are stacked in sequence and placed in the mold, and the mold is hot-pressed at a temperature of 100°C to 180°C, a pressure of 0.5MPa to 1.5MPa, and a duration of 5 seconds to 30 seconds. Through high temperature and high pressure treatment of a specific mold, the bonding strength of the composite adhesive layer is ensured to reach 2-5N / cm (test results), and the consistency of the production process is improved, reducing the risk of material delamination or shedding.

[0037] Wide range of effects

[0038] This product can use different materials according to the characteristics and uses of the product starting from the characteristic material layer. For example, sponge, TPE, rubber, etc. can be used to make carpets. Clothing can directly add a layer of clothing fabric, and different functional layers can be attached according to needs.

[0039] The key to the present invention is to design a composite adhesive layer, which is formed by combining a first fabric layer, a TPU film layer and a second fabric layer by hot pressing or gluing. The successful design of the composite adhesive layer effectively improves the overall stability of the multilayer structure and ensures the long-term performance of the fabric in various environments, such as waterproofness, moisture permeability and durability. Through the above technical effects, the cooling composite product of the present invention is superior to the existing technology in terms of cooling performance, waterproofness and moisture permeability, composite stability and comfort, and provides a reliable solution for the development of summer cooling products.
