Description

TECHNICAL FIELD

[0001] The present application belongs to the field of textile materials and technology, and relates to a heat and moisture transfer functional tubular composite fabric and its use. BACKGROUND

[0002] The most important indicators when measuring the comfort of clothing are the moisture resistance and thermal resistance of the clothing. Currently known clothing thermal resistance test methods include outdoor mannequin comparison test method, evaporation heat plate method and thermal mannequin clothing test method. The outdoor mannequin comparison test method has high cost, many variables, large test error and low repeatability. The evaporation heat plate method has high test precision and good repeatability, but the clothing needs to be cut into a size specified by the instrument for sampling during the test, which destroys the structure of the clothing, and the influence of the combination of components of the clothing on the thermal resistance is not considered, so the method is not suitable for testing the thermal resistance of clothing made of several materials combined and sewn.

[0003] The thermal mannequin is an instrument for simulating the heat and moisture exchange between the human body and the environment, which can be used in the fields of clothing, aerospace, firefighting, etc., and is mostly used for evaluating the comfort of clothing. The biggest advantage of the thermal mannequin is that it can simulate the actual wearing environment of the human body, and it is the most scientific and objective method for evaluating the comfort of clothing. The thermal mannequin clothing test method does not need to cut the clothing during the test, but only needs the thermal mannequin to wear the clothing product to directly test the thermal resistance of the clothing, which avoids the influence of individual differences in real human experiments, has high experimental precision and good repeatability, can objectively and systematically evaluate the thermal environment, can solve the problems caused by the selection of test persons, greatly shortens the experimental period, greatly reduces the experimental cost, and therefore the thermal mannequin is recognized as an advanced device essential for human ergonomics research.

[0004] Although the thermal mannequin has many advantages, it still needs to be compared with real human experiments to accurately and comprehensively evaluate and test. The first disadvantage of the thermal mannequin is the difference between the real human body and the mannequin model. For the human body, heating and sweating do not occur uniformly, and the thermal mannequin can only simulate the average heating and dissipation of the human body, and cannot completely simulate the physiological characteristics of the human body. In addition, the accurate thermal mannequin is expensive, with a cost of hundreds of thousands of yuan or even higher, and is difficult to repair. Therefore, it is necessary to provide a new functional tubular composite fabric for evaluating the comfort of clothing to simulate the limbs of the mannequin and solve the above technical problems.

[0029] As Figure 1 , Figure 2 , Figure 3As shown, a functional tubular composite fabric for heat and moisture transfer comprises four parts: a high-modulus and heat-insulating core layer 1, a highly elastic covering layer 2, a liquid transport layer 3, and a waterproof and breathable outer skin layer 4. The high-modulus and heat-insulating core layer is composed of a high-modulus heat-insulating rigid composite material and heat-insulating cotton. The highly elastic covering layer is composed of continuous silicone and spiral structure yarns capable of being filled with liquids and gases, with the spiral structure yarns embedded within the silicone. The liquid transport layer is composed of a waterproof and breathable porous membrane with an etched surface... The device consists of a microporous water delivery hose, a heat-conducting membrane, and a heating wire. The waterproof and breathable outer skin layer is composed of an elastic woven fabric layer (nylon), a hydrophobic porous film layer (PTFE), and a porous nonwoven fabric layer. The heat and moisture transfer performance of this functional tubular composite fabric is achieved by the breathable hose of the liquid delivery layer discharging liquid at a certain temperature through the micropores on its surface. The liquid is absorbed by the nonwoven fabric core and output by the hydrophobic porous film layer as moisture at a certain temperature, which permeates through the outer skin layer to achieve heat and moisture transfer of the liquid at a certain temperature.

[0030] like Figure 3 As shown, the core layer 1 of the present invention comprises a high-modulus thermally insulating rigid composite material 5 and thermally insulating cotton 6. The rigid composite material has a certain hardness and is not easily bent. The thermally insulating cotton covers the outside of the rigid composite material. The core layer can have a certain rigidity like human bone, so as to simulate human bone.

[0031] like Figure 3 As shown, the highly elastic coating layer 2 of the present invention is composed of continuous silicone 8 and a spiral structure yarn 7 that can be filled with liquid and gas. After the spiral structure yarn is filled with liquid and gas, it is embedded into the continuous tubular silicone by implantation. The coating layer wraps around the surface of the core layer and has a certain degree of elasticity and tensile strength.

[0032] like Figure 3 As shown, the liquid transport layer 3 of the present invention is composed of a waterproof and breathable porous membrane 12, a water delivery hose 11 with micropores on its surface, a heat-conducting membrane 10, and a heating wire 9. The heating wire is non-uniformly wound around the outside of the coating layer to generate heat. The heat-conducting membrane covers the outside of the heating wire, and the breathable hose is non-uniformly wound around the outside of the heat-conducting membrane. The winding pattern imitates the distribution pattern of the main blood vessels in the human body in order to simulate the heat generation pattern of the human body.

[0033] The thermal conductive film 10 is a material that can transfer heat evenly, including: a thin film made of thermally conductive silicone, a thermally conductive pad, a thin film made of thermally conductive potting compound, aluminum foil, etc. The thermal conductive film can distribute the heat generated by the heating wire evenly.

[0034] The water transport hose 11 is a tubular material made of a composite fabric with micro-holes on the surface, and the raw materials include cotton, flax, hemp or chemical fibers. After being made into a tube, the surface is engraved with micro-holes to allow the water in the tube to be properly discharged, so as to simulate human sweating.

[0035] As shown in Figure 3 The waterproof and moisture-permeable skin layer 4 of the present application is composed of an elastic woven fabric layer 15, a hydrophobic porous film layer 14 and a porous non-woven fabric layer 13, and covers the surface of the transport layer, has certain elasticity, flexibility, air and moisture permeability, and achieves the purpose of simulating human skin.

[0036] The porous non-woven fabric is a material with wicking function, which is made of polyurethane fiber, polypropylene fiber, high-dry four-channel polyester fiber, viscose fiber, wool fiber, hemp fiber, cotton fiber, bamboo fiber and the like. It has high moisture absorption function and can make the water generated inside evenly distributed in the layer. When subjected to external pressure, more liquid will be discharged from the corresponding part to simulate the non-uniform sweating of the human body.

[0037] A method for realizing the heat and moisture transfer performance of a functional tubular composite fabric, the way to realize the heat and moisture transfer performance of the functional tubular composite fabric is:

[0038] (1) Heat transfer

[0039] The heating wire in the transport layer for transporting liquid generates certain heat which gradually spreads and transfers to the outside. Since the heating wire is thin, the generated heat cannot be evenly distributed, so a heat-conducting film is added to the outer layer. The heat-conducting film can make the heat generated by the heating wire evenly distributed, gradually transfer heat to the outside, and achieve the effect of heat transfer.

[0040] (2) Moisture transfer

[0041] The moisture-permeable water transport hose with micro-holes on the surface in the transport layer for transporting liquid discharges liquid with a certain temperature through the micro-holes on the surface. The liquid is permeated to the porous non-woven fabric through the waterproof and moisture-permeable porous membrane. The wicking and diffusion of the porous non-woven fabric evenly distribute the moisture to the porous non-woven fabric, and then output the moisture with a certain temperature through the hydrophobic porous film layer. The moisture is discharged to the outside of the skin layer, thereby realizing the heat and moisture transfer of the liquid with a certain temperature. Alternatively, when the moisture in the porous non-woven fabric cannot diffuse in time, a high relative humidity environment is formed, and the moisture condenses into liquid in the porous non-woven fabric. The liquid is evenly distributed in the non-woven fabric through the wicking of the porous non-woven fabric, and then the liquid in the non-woven fabric outputs the moisture with a certain temperature through the hydrophobic porous film layer. The moisture is discharged to the outside through the skin layer, thereby realizing the heat and moisture transfer of the liquid with a certain temperature.

[0042] The heat and moisture transfer functional tubular composite fabric has similar characteristics to human limbs, such as human sweating, limb movement, blood circulation, body heat production, elastic muscles, elastic skin and the like. The tubular composite fabric of the present application can be used to make a bionic artificial limb for a warm body artificial person, and can be used for testing the comfort of gloves, ice sleeves, socks, trousers, silk stockings and the like.
