Description

Technical Field

[0001] The present invention relates to the technical field of textile materials, and particularly to a cold-sensing composite product with a multi-layer composite structure for manufacturing cold-sensing products.

Background Art

[0002] With the improvement of people's living standards, the demand for comfort and functionality of textile products has gradually increased. Especially in hot seasons, fabrics with a cold-sensing effect have been widely noticed. Currently, commercially available cold-sensing composite products are mainly realized in the following several ways.

[0003] Addition of cold-sensing materials: By adding cold-sensing fibers during spinning or applying a cold-sensing coating, a temperature-lowering effect can be generated when the fabric contacts the skin. However, the temperature-lowering effect of such cold-sensing composite products is often affected by environmental temperature and humidity, and it is difficult to maintain coolness over a long period.

[0004] Moisture-absorbing and quick-drying structure: By using fiber materials with high moisture absorption or quick-drying properties, the evaporation of sweat on the body surface is accelerated to achieve a temperature-lowering effect. However, such products mainly rely on the sweating function of the human body, and their temperature-lowering effect is limited, and the requirements for breathability are high.

[0005] Multi-layer composite fabric: Some cold-sensing composite products use a multi-layer structure design, and by combining a functional film material and a textile layer, functions such as temperature reduction, waterproofing or ventilation are realized. However, in the prior art, the combination of functions of the multi-layer structure is limited, and it is particularly difficult to simultaneously achieve the effects of waterproofing, cold-sensing and ventilation.

[0006] Based on the technical challenges described above, conventional cooling composite products still have significant room for improvement in terms of breathability, waterproofing, and sustained cooling performance. Therefore, there is an urgent need to develop a composite fabric that can simultaneously possess cooling, waterproofing, and breathability properties to meet the usage needs of consumers in various application scenarios. This fabric has a long-lasting cooling effect and can maintain its functional stability by being washed by hand or other gentle methods. In conventional technology, cooling composite products are prone to problems such as layer separation and detachment during use due to insufficient bonding strength between different material layers, and this is especially likely to occur at the bonding site between the TPU film and the fabric or gel. The design of the composite adhesive layer according to this invention successfully achieves high-strength bonding between materials using a hot press or bonding process, providing technical assurance for the sustained use of the composite fabric. [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] To address the shortcomings of conventional cooling composite products in terms of breathability, waterproofing, and sustained cooling performance, this invention provides a cooling composite product with excellent cooling effect, waterproofing, and breathability, resulting in high comfort and applicability, through the design of a multi-layer composite structure. [Means for solving the problem]

[0008] The technical means of the cooling composite product of this invention are as follows:

[0009] Cooling composite products are constructed by layering fabric in the order of an upper composite adhesive layer and an intermediate gel layer, with an overall thickness of 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 bonded together by hot pressing or adhesive to form the composite adhesive layer.

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

[0012] Preferably, a sealing layer is provided on the other side of the characteristic material layer, and the second fabric layer is provided as a permeable fabric layer. The sealing layer is a TPU film layer and may be a waterproof surface, but the waterproof layer of the waterproof fabric faces away from the gel layer.

[0013] Preferably, a base layer of the dough is provided on the other side of the sealing layer.

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

[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, the cooling composite product is manufactured as a mat with a thickness of 1 mm to 1 cm.

[0017] In the use of the cooling composite product described above, the cooling composite product is manufactured into clothing, bedding, eye masks, or arm covers with a thickness of 0.5 to 5 mm.

[0018] The processing method for the cooling composite product described above is: Step A involves overlapping the first fabric layer, the TPU film layer, and the second fabric layer, and bonding them to a composite adhesive layer by hot pressing or bonding. Step B involves uniformly applying a gel layer to the surface of the composite adhesive layer, The method includes step C, which involves providing a characteristic material layer on the other side of the gel layer.

[0019] Preferably, in processing step A, a mold is prepared in advance according to the size of the dough, and the composite adhesive layer is hot-pressed within the mold.

[0020] The aforementioned fabrics are applicable to the manufacture of cooling mats, cooling clothing, or other heat-reducing products.

[0021] The number of layers of the product of the present invention can be set according to the functional needs, and it 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 flexible material such as sponge, other functional layers can be further added to perform sealing and waterproofing, and specifically, it can be set according to the needs of the user.

Advantages of the Invention

[0022] The cold-sensing composite product provided by the present invention realizes the following technical effects through the design of a specific multi-layer composite structure.

[0023] Sustainable cold-sensing performance: This fabric has a long-lasting cold-sensing effect and can maintain functional stability by washing it by hand or in other gentle ways.

[0024] [[ID=I7]]Combination of waterproof and moisture-permeable performance: The TPU film layer has excellent waterproof performance, can effectively prevent the intrusion of moisture from the outside, and at the same time, its moisture-permeable characteristics enable the discharge of moisture, avoiding a stuffy feeling and improving the comfort of the entire fabric.

[0025] Effective fusion of the composite structure: As an important intermediate layer, the TPU film layer effectively solves the problem that it is difficult to composite the fabric layer and the gel layer, ensures that each layer can be firmly bonded during the composite process, and forms a stable multi-layer structure.

[0026] Air permeability and flexibility: The first fabric layer and the second fabric layer are made of spun fabric materials, having both air permeability and flexibility, ensuring the comfort and skin affinity when the fabric contacts the skin, and being applicable for long-term wearing or use.

[0027] Structural stability and durability: Each layer is firmly bonded by hot pressing, adhesive, or direct coating processes, ensuring a stable overall structure for the fabric, allowing it to withstand repeated use and washing, and improving the product's lifespan and market applicability.

[0028] In step A, the first fabric layer, TPU film layer, and second fabric layer are precisely positioned using a mold of a specific design and bonded by hot pressing using the mold's high temperature and high pressure function. A high temperature resistant coating is applied to the surface of the mold to prevent material adhesion and provide a uniform pressure distribution, making the bond of the composite adhesive layer stronger. The first fabric layer, TPU film layer, and second fabric layer are stacked in order and placed in the mold, and the mold is used for hot pressing. The hot pressing temperature is 100°C to 180°C, the pressure is 0.5 MPa to 1.5 MPa, and the duration is 5 to 30 seconds. The high temperature and high pressure treatment of the specific mold ensures that the adhesive strength of the composite adhesive layer reaches 2 to 5 N / cm (test result), improving consistency in the production process and reducing the risk of material layer separation or detachment.

[0029] Versatility: This product can utilize different materials for its characteristic material layer depending on the product's properties and application. For example, in the case of carpets, sponge, TPE, rubber, etc., can be used. In the case of clothing, a layer of clothing fabric can be added directly, and different functional layers can be combined as needed.

[0030] The key point of this invention is the design of a composite adhesive layer formed by bonding a first fabric layer, a TPU film layer, and a second fabric layer by hot pressing or adhesive bonding. 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 under various environmental conditions, such as waterproofness, breathability, and durability. Due to these technical effects, the cooling composite product of this invention is superior to conventional technology in terms of cooling performance, waterproofness and breathability, composite stability, and comfort, providing a reliable solution for the development of cooling products for summer.
