[0006] Based on this, the present invention provides a windproof and warm-keeping polyester fabric and a preparation process thereof. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a windproof and warm-keeping polyester fabric and a preparation process thereof.

[0008] On the one hand, the present invention provides a windproof and warm polyester fabric, which comprises a warm fabric layer, a breathable fabric layer and a windproof layer from the inside to the outside; the warm fabric layer is formed by weaving wool, cotton and linen fibers and polyester fibers, and the breathable fabric layer is formed by weaving cotton fibers, polyester fibers, bamboo charcoal fibers and nylon.

[0010] Furthermore, the weight ratio of wool, cotton and linen fibers and polyester fibers in the thermal insulation fabric layer is (20-22): (10-14): (40-50).

[0011] Furthermore, the warp density of the breathable fabric layer is 580-600 strands / 10cm, and the weft density is 500-520 strands / 10cm.

[0012] Furthermore, the weight ratio of cotton fiber, polyester fiber, bamboo charcoal fiber and nylon in the breathable fabric layer is (16-20): (30-34): (8-10): (14-16).

[0013] Furthermore, the windproof layer comprises the following materials in parts by weight: 40-50 parts of aqueous acrylic emulsion, 6-8 parts of chitosan modified hollow glass microspheres, 3-4 parts of modified zirconium dioxide, 2-4 parts of dodecyl alcohol ester, 0.5-1 part of defoaming agent, and 0.5-1 part of dispersant.

[0014] Furthermore, the preparation method of the chitosan-modified hollow glass microspheres comprises: adding chitosan to glacial acetic acid, stirring at a rotation speed of 1200-1600 r / min for 2-3 hours, then adding glass microspheres and continuing to stir at a rotation speed of 2200-2400 r / min for 2-3 hours; centrifuging, washing with deionized water for 3-4 times, and drying at a temperature of 55-65°C for 20-24 hours.

[0015] Furthermore, the concentration of the glacial acetic acid is 0.5-0.7 mol / L, and the weight ratio of the chitosan, glacial acetic acid and glass microbeads is (2-3): (140-160): (4-5).

[0016] Furthermore, the preparation method of the modified zirconium dioxide comprises: adding zirconium dioxide dried to constant weight into an ethanol solution, then adding a silane coupling agent, stirring at 500-600 r / min for 1-1.2 hours, and then filtering, drying the solid obtained by filtration at a temperature of 55-65°C for 4-6 hours, and grinding it through a 100-mesh filter.

[0017] Furthermore, the preparation method of the modified zirconium dioxide comprises: the weight ratio of the zirconium dioxide, ethanol and silane coupling agent is (10-12): (14-16): (0.3-0.5).

[0018] Furthermore, the silane coupling agent is silane coupling agent KH560.

[0019] On the other hand, the present invention provides a preparation process of a windproof and warm polyester fabric, the steps comprising: (1) Preparation of windbreak layer: Mix water-based acrylic emulsion and dodecyl alcohol ester, add defoamer and dispersant in sequence at 500-600 r / min and stir for 20-30 min, then continue to add modified zirconium dioxide and stir for 10-15 min; finally, add chitosan modified hollow glass microspheres, adjust the speed to 300-400 r / min and continue stirring for 40-60 min; (2) Preparation of windproof and warm polyester fabric: Place the warm fabric layer and the breathable fabric layer together, and evenly coat the prepared windproof layer on the outer surface of the breathable fabric layer at a coating amount of 10-12 mL / mm 2 , the bonding is carried out at a temperature of 60-70°C, a vehicle speed of 8-10m / min, and a bonding pressure of 2-3KPa.

[0020] The beneficial effects of the present invention are: The thermal insulation fabric layer of the present invention is woven by weaving wool, cotton and linen fibers and polyester fibers. The combination of these fibers can form an effective thermal insulation layer, store air and reduce heat loss. Wool and cotton and linen fibers have good thermal insulation performance, while polyester fibers provide wear resistance and easy care. At the same time, the high density of the thermal insulation fabric layer (the warp density is 700-720 strands / 10cm and the weft density is 640-680 strands / 10cm) further enhances its thermal insulation effect, because the high-density fabric can more effectively block the invasion of external cold air.

[0021] The breathable fabric layer of the present invention is woven from cotton fiber, polyester fiber, bamboo charcoal fiber and nylon. The combination of these fibers not only provides good air permeability, but also can absorb moisture and perspiration to keep the body dry and comfortable. The lower density of the breathable fabric layer (the density in the warp direction is 580-600 strands / 10cm, and the density in the weft direction is 500-520 strands / 10cm) not only maintains air permeability, but also enhances the overall structural strength of the fabric.

[0022] The thermal insulation fabric layer and the breathable fabric layer of the present invention are made of a combination of multiple fibers, which are interwoven during the weaving process to form a stable structure. At the same time, the high-density weaving method further enhances the overall structural strength of the fabric, making it more wear-resistant and durable.

[0023] The hollow glass microspheres in the present invention have a unique cavity structure, which can effectively store air, form an insulation layer, and reduce heat loss. Chitosan is a natural polymer with good biocompatibility and film-forming properties. Through chitosan modification, the bonding force between the hollow glass microspheres and the fabric substrate can be enhanced, and at the same time, the coating can be given certain antibacterial and moisturizing properties. The chitosan-modified hollow glass microspheres form a dense coating on the surface of the fabric, which effectively blocks the invasion of external cold air and reduces the loss of internal heat, thereby improving the windproof and warm-keeping properties of the fabric.

[0024] The modified zirconium dioxide in the present invention plays a role of skeleton in the coating, enhancing the hardness and wear resistance of the coating and making the fabric more durable. Although zirconium dioxide itself does not have thermal insulation properties, its uniform distribution in the coating can form more tiny thermal insulation spaces, and together with the chitosan-modified hollow glass microspheres, improve the thermal insulation effect of the fabric.

[0025] In addition, the softness and hollow structure of chitosan-modified hollow glass microspheres complement the hardness and wear resistance of modified zirconium dioxide. This structural complementarity allows the coating to have higher strength and toughness while maintaining softness. Due to the synergistic effect of chitosan-modified hollow glass microspheres and modified zirconium dioxide, the overall strength of the coating is improved. This increase in strength allows the fabric to more effectively resist tearing and abrasion when subjected to external forces. By improving the tear strength and abrasion resistance of the fabric, the service life of the fabric can be significantly extended and the replacement frequency due to wear can be reduced.

[0026] The windproof layer of the present invention is made of water-based acrylic emulsion, chitosan-modified hollow glass microspheres, modified zirconium dioxide and other materials, wherein the chitosan-modified hollow glass microspheres and modified zirconium dioxide and other materials not only improve the windproof effect of the fabric, but also enhance the toughness and hardness of the coating. These materials form a stable network structure in the coating, thereby improving the tear strength and wear resistance of the fabric. DETAILED DESCRIPTION
