Description

Technical Field

[0001] This invention belongs to the field of composite fabric technology, specifically relating to a composite fabric and its preparation method. Background Technology

[0002] Composite fabrics are created by directly heating and bonding fabric with an elastomer membrane to form a new composite fabric, thereby achieving windproof, moisture-wicking, UV protection, and skin-friendly properties.

[0003] Windproofness and breathability are important indicators for evaluating the warmth and comfort of composite fabrics. The windproofness of composite fabrics mainly depends on the performance of the resulting elastomeric membrane; the density of the elastomeric membrane determines the waterproof and windproof function of the composite fabric. The breathability of the fabric is mainly affected by the breathability of the elastomeric membrane material itself. Existing technologies using elastomeric membranes for composite fabrics include fluoropolymer microporous membranes and TPU microporous membranes. These membranes utilize their own micropores to enable the composite fabric to exhibit breathable and breathable properties.

[0004] However, since the elastomer membrane used in existing composite fabrics is a microporous membrane, when the fabric and the elastomer membrane are laminated using solvent adhesives or hot melt adhesives, the adhesive can easily penetrate into the micropores, causing blockage or sealing of the micropores in the elastomer membrane, thus resulting in poor air permeability and moisture permeability of the composite fabric. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a composite fabric and its preparation method. This invention develops a windproof and breathable membrane for composite fabrics, which itself does not possess a microporous structure. When the windproof and breathable membrane is heated and bonded to a fabric to form a composite fabric, during the heating and bonding process, the molten ethylene-butene copolymer elastomer in the windproof and breathable membrane gradually permeates into the fibers of the fabric. The fabric gradually absorbs the molten ethylene-butene copolymer, and the microporous structure of the windproof and breathable membrane begins to appear. As more ethylene-butene copolymer melts and seeps out, the microporous structure of the windproof and breathable membrane becomes more prominent, resulting in stronger breathability of the composite fabric.

[0006] The windproof and breathable membrane of this invention uses ethylene-butene copolymer elastomer as the main film-forming material and polyolefin elastomer as the reinforcing material. An interpenetrating network polymer is formed by mixing and heating the polyolefin elastomer and ethylene-butene copolymer elastomer, resulting in a composite thermoplastic elastomer. Then, by adding mineral powder, which has a high porosity, and under the flow of soft wax and softening oil, the composite thermoplastic elastomer forms a continuous sea, with the mineral powder forming dispersed islands, creating a sea-island structure, thus obtaining the windproof and breathable membrane. This invention utilizes the composite thermoplastic elastomer and soft wax to form a continuous and dense elastomer film, improving the windproof and waterproof properties of the composite fabric after lamination with the elastomer film; and, with the help of the mineral powder, achieves the breathability and moisture permeability of the composite fabric.

[0007] The composite fabric and its preparation method of the present invention are achieved through the following technical solution:

[0008] The first objective of this invention is to provide a composite fabric comprising a first fabric, a windproof and breathable membrane, and a second fabric; wherein the fibers of the first fabric and the second fabric are infiltrated into the windproof and breathable membrane by hot pressing.

[0009] The raw materials for preparing the windproof and breathable membrane, by weight percentage, include the following components: ethylene-butene copolymer elastomer: 39%~92.4%, polyolefin elastomer: 2%~15%, soft wax: 2%~13%, mineral powder: 3%~8%, softening oil: 0.1%~9%, ultraviolet absorber: 0.5%~3%, totaling 100%.

[0010] It should be noted that ethylene-butene copolymer elastomers, as the main film-forming material, possess the characteristic of high-temperature melting and physical cross-linking upon cooling to form elastomers. Ethylene-butene copolymers exhibit good heat resistance, weather resistance, and excellent mechanical properties. Their embrittlement temperature is below -70℃, and their maximum service temperature reaches 140℃. After 100 hours of ozone aging at 38℃, their performance decreases by less than 10%. The tensile elongation is greater than 500%, the tensile recovery rate is greater than 90%, and the tensile strength is greater than 20 kPa. Furthermore, ethylene-butene copolymer elastomers possess both plasticity and high elasticity, combining the properties of both plastics and rubber, and can be directly thermoplasticized without vulcanization. A composite thermoplastic elastomer with an interpenetrating network structure is formed by mixing and heating ethylene-butene copolymer elastomers and polyolefin elastomers. Preferably, the ethylene-butene copolymer elastomer is a mixture of low molecular weight ethylene-butene copolymer rubber and high molecular weight ethylene-butene copolymer rubber; the low molecular weight ethylene-butene copolymer rubber is 0.1 to 0.7 times the mass of the high molecular weight ethylene-butene copolymer rubber; the low molecular weight is less than 100,000; and the high molecular weight is greater than 150,000.

[0011] Polyolefin elastomers are elastomers that can be directly thermoplasticized without vulcanization. The role of polyolefin elastomers is to form an interpenetrating network structure with ethylene-butene copolymers, thereby forming a composite thermoplastic elastomer. This enhances the density and strength of the ethylene-butene copolymer elastomer, improving the windproof and waterproof properties of the composite fabric.

[0012] It should also be noted that the raw materials for preparing the windproof and breathable membrane also include phase change energy storage wax. When the elastomer membrane and fabric are heated and laminated, the phase change energy storage wax melts into a liquid and absorbs a large amount of energy. At this time, the phase change energy storage wax, together with the molten ethylene-butene copolymer, is impregnated into the fiber. When the composite fabric is further cooled, the phase change energy storage wax slowly releases latent heat, helping to prolong the solidification time of the ethylene-butene copolymer, delaying the physical cross-linking process of the ethylene-butene copolymer, and increasing the permeation effect of the ethylene-butene copolymer and the fiber. Therefore, the phase change energy storage wax has an auxiliary temperature control function. This invention, by adding phase change energy storage wax, allows the phase change energy storage wax to play a role in regulating and controlling the temperature during the lamination process of the elastomer membrane and fabric. Furthermore, during the lamination process of the elastomer membrane and the fabric, the amount of phase change energy storage wax added can be determined based on the temperature control and cooling function of the actual laminating machine. When the laminating machine has segmented and time-based temperature control and cooling functions, the effect of phase change energy storage wax is relatively low, and it can be added in small amounts or not at all, relying mainly on the cooling system of the laminating machine to regulate the physical crosslinking time of the ethylene-butene copolymer. When the laminating machine does not have segmented and time-based temperature control and cooling functions, phase change energy storage wax plays a crucial auxiliary role in temperature control. The content of the phase change energy storage wax should not exceed 13% of the windproof and breathable membrane. The molecular structure of the phase change energy storage wax is mainly composed of straight-chain alkanes, with low content of branched and cyclic hydrocarbons, thus making the phase change energy storage wax hard and brittle. Preferably, the phase change energy storage wax is a n-alkane wax.

[0013] Soft wax possesses flexibility, extensibility, and viscosity, and exhibits good compatibility with composite thermoplastic elastomers. During mixing with composite thermoplastic elastomers, it acts as a plasticizer, improving the flowability of the mixture. While maintaining the elasticity and softness of the composite thermoplastic elastomer, it does not compromise its tensile and recovery properties, and offers advantages such as low migration and exudation, good stability, and resistance to aging and yellowing. Furthermore, the formation of a continuous and dense elastomer film using the composite thermoplastic elastomer and soft wax achieves the waterproof and windproof properties of the composite fabric.

[0014] Mineral powder is porous, breathable, moisture-permeable, and non-melting, remaining in a porous solid state throughout the thermoplastic processing with composite thermoplastic elastomers; furthermore, the deformation difference between mineral powder and composite thermoplastic elastomers is significant. Due to interfacial deformation, micropores easily form in the composite thermoplastic elastomer. Moreover, since composite thermoplastic elastomers and soft waxes are highly hydrophobic and have poor breathability and moisture permeability, this invention utilizes the porous hydrophilicity of mineral powder to achieve the breathability and moisture permeability of the windproof and moisture-permeable membrane. Preferably, the mineral powder is one of calcium carbonate, quartz sand, talc, montmorillonite, kaolin, and bentonite.

[0015] Softening oil is used to adjust the fluid properties of the melt. Considering material compatibility: softening oil has high compatibility with ethylene-butene copolymer elastomers, but low compatibility with polyolefin elastomers; to improve compatibility when mixed, the amount of softening oil added needs to be controlled in the raw materials for preparing the windproof and breathable membrane. Preferably, the softening oil is white mineral oil with a viscosity greater than 35 cSt.

[0016] This invention provides UV protection by adding a UV absorber to absorb UV light in the 320nm-400nm wavelength range and outdoor UV light, thereby reducing or inhibiting the UV oxidation process of the polymer. Preferably, the UV absorber is one of benzotriazole and benzophenone.

[0017] A second objective of this invention is to provide a method for preparing the aforementioned composite fabric, comprising the following steps:

[0018] S1. Weigh out the corresponding mass of raw materials according to the proportion of raw materials for the preparation of the windproof and breathable membrane, and set aside for later use.

[0019] S2. Mix ethylene-butene copolymer elastomer and polyolefin elastomer at 60℃~100℃ to obtain composite thermoplastic elastomer.

[0020] S3. Add soft wax, mineral powder, softening oil and ultraviolet absorber to the composite thermoplastic elastomer, stir evenly, and then add phase change energy storage wax in batches to obtain a windproof and moisture-permeable membrane.

[0021] S4. The first fabric, the windproof and breathable membrane, and the second fabric are stacked in sequence to form a sandwich structure. After heating, pressure is applied to mechanically bond the fabric and the windproof and breathable membrane together to obtain a composite fabric.

[0022] Preferably, the mixing time in S1 is 10 min to 20 min, which is used to mix the polyolefin elastomer and the ethylene-butene copolymer elastomer evenly to form a composite thermoplastic elastomer of interpenetrating network polymer.

[0023] To ensure the mineral powder, softening oil, and ultraviolet absorber are fully dispersed in the composite thermoplastic elastomer, a continuous sea is formed by the composite thermoplastic elastomer and dispersed islands by the flowing wax and softening oil, resulting in a sea-island structure and a windproof and breathable membrane. In process S3 of this invention, mechanical stirring is employed; preferably, the stirring time in S3 is 20-30 minutes.

[0024] To ensure the phase change energy storage wax is uniformly dispersed in the composite thermoplastic elastomer and that the two are mutually absorbed and integrated, this invention employs a phased addition method. The phase change energy storage wax is added to the composite thermoplastic elastomer in stages, and then mixed evenly by mechanical stirring or kneading until the phase change energy storage wax and the composite thermoplastic elastomer are fully adsorbed and mixed. Furthermore, the heating temperature during the stirring process is controlled at 60℃~100℃ to ensure that the phase change wax is in a molten state and that the melt is completely adsorbed by the ethylene-butene copolymer, resulting in a windproof and breathable membrane.

[0025] Preferably, the pressure applied in S4 is 15 MPa to 50 MPa, and the heating temperature is 120°C to 180°C.

[0026] Preferably, the first fabric and the second fabric are made of the same material.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The composite fabric of this invention comprises a first fabric, a windproof and breathable membrane, and a second fabric. Fibers from the first and second fabrics are infiltrated into the windproof and breathable membrane via hot pressing. The raw materials for preparing the windproof and breathable membrane include ethylene-butene copolymer elastomer, polyolefin elastomer, soft wax, mineral powder, softening oil, and ultraviolet absorber. This invention obtains a composite thermoplastic elastomer through an interpenetrating network polymer formed by polyolefin elastomer and ethylene-butene copolymer elastomer. The composite thermoplastic elastomer and soft wax form a continuous and dense elastomer film, thereby improving the windproof and waterproof properties of the composite fabric after lamination with the windproof and breathable membrane. By adding mineral powder, which has a high porosity, under the flow of soft wax and softening oil, the composite thermoplastic elastomer forms a continuous sea, with the mineral powder as dispersed islands, creating a sea-island structure, thus obtaining the windproof and breathable membrane. The island structure achieves the waterproof and windproof properties of the composite fabric, while the porous mineral powder provides breathability and moisture permeability.

[0029] The windproof and breathable membrane prepared by this invention does not have a microporous structure itself. When the windproof and breathable membrane is heated and bonded to a fabric to form a composite fabric, during the heating and bonding process, the high-temperature molten ethylene-butene copolymer elastomer gradually penetrates into the fabric fibers. The fabric gradually absorbs the molten ethylene-butene copolymer, and the microporous structure begins to appear. As more ethylene-butene copolymer elastomer melts and seeps out, the microporous structure of the windproof and breathable membrane becomes more prominent, and the breathability of the composite fabric becomes stronger. In addition, when the molten ethylene-butene copolymer elastomer cools, a cross-linking reaction occurs again, forming cross-linked elastomers both inside and outside the fabric fiber structure. This results in both sides of the fabric lamination layer being elastomer materials, which are firmly bonded, soft and elastic, resistant to rubbing without creases, washable, and difficult to delaminate, bubble, or peel.
