Description

Technical Field

[0001] This utility model relates to the field of thermal insulation fabric technology, and more specifically, it relates to a thermal insulation fabric. Background Technology

[0002] Polyester fabric is a type of fabric woven from polyester fibers. Due to its tight molecular structure, polyester fibers have good windproof properties and are widely used in the production of windproof and warm clothing.

[0003] With increasing market competition, fabric weaving density and thickness are often increased to improve warmth, or windproof coatings are applied. This makes the resulting garments thicker and heavier, making them bulky and restricting movement. At the same time, the tight molecular structure of polyester fibers reduces the pores and surface area within the fibers, hindering moisture penetration and diffusion. As a result, the wearer's sweat cannot be absorbed and released in time, remaining on the skin and affecting comfort. This is especially true when the fabric is thick, as the absorbed sweat cannot be released quickly, leading to a warm and humid environment that breeds bacteria and produces odors. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a thermal insulation fabric.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a thermal insulation fabric, comprising an inner layer and an outer layer, wherein a support strip is woven on the side of the outer layer near the inner layer, and the support strip forms several thermal insulation areas one and several thermal insulation areas two on the surface of the outer layer. Moisture-dissipating blocks and fleece blocks are respectively provided on both sides of the thermal insulation areas one, wherein the moisture-dissipating blocks and fleece blocks have the same moisture absorption and greater than the moisture absorption of the inner layer. The inner layer and the outer layer are heat-pressed together at the support strip. After the thermal insulation areas one are combined with the inner layer and the outer layer, they are supported by the fleece blocks to form a thermal insulation cavity one. After the thermal insulation areas two are combined with the inner layer and the outer layer, they form a thermal insulation cavity two.

[0006] The present invention is further configured such that: the cross-sectional shape of the first insulating area, the fleece block, and the moisture-dissipating block are all regular hexagonal; the side lengths of the fleece block and the moisture-dissipating block are the same and smaller than the side length of the first insulating area; and the moisture-dissipating block and the fleece block are formed by tufting on the first insulating area using moisture-dissipating yarn.

[0007] The present invention is further configured such that: the cross-sectional shape of the second heat-insulating area is square, and several first heat-insulating areas and several second heat-insulating areas are arranged alternately, and the thickness of the fleece block is greater than the thickness of the abutment strip.

[0008] The present invention is further configured such that: the outer layer of the knitting structure is a small jacquard structure, the ground yarn and the weft jacquard float yarn of the small jacquard structure are both windproof yarns, and the support strip is formed by several windproof yarns arranged in parallel floating on the ground surface.

[0009] The present invention is further configured such that: the weave structure of the inner layer is a plain weave structure, and both the warp and weft yarns of the inner layer are moisture-wicking yarns.

[0010] The present invention is further configured such that: the moisture-wicking yarn is made of a blend of polyester fiber and wool fiber, the windproof yarn is made of twisted polyester fiber, the moisture-wicking yarn is made of twisted polyester profiled fiber, and the moisture-wicking yarn has a greater moisture absorption than the moisture-wicking yarn.

[0011] In summary, this utility model has the following beneficial effects: the support strips and fleece blocks create several insulating cavities 1 and 2 between the inner and outer layers. The insulating cavities 1 are filled with wool fibers, which allows them to better retain the temperature generated by the body surface. Air, as a poor conductor of heat, allows the insulating cavities 2 to effectively reduce temperature transfer between the two sides, while also reducing the overall weight of the fabric and improving the warmth retention and wearing comfort. Since the moisture-wicking blocks and fleece blocks have greater hygroscopicity than the inner layer, the moisture absorbed by the inner layer can be quickly dissipated through the fleece blocks and fully contacted with the external airflow, thus keeping the inner layer and skin dry.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Example: A thermal insulation fabric, such as Figures 3-6 As shown, it includes an inner layer 1 and an outer layer 2. The outer layer 2 has a support strip woven on the side close to the inner layer 1. The outer layer 2 is woven with a small jacquard weave. The ground yarn and weft jacquard float yarn of the small jacquard weave are both windproof yarns. The outer layer 2 is woven by a multi-arm loom. The support strip is formed by several windproof yarns arranged in parallel on the ground surface. The windproof yarns are made of twisted polyester fibers. Due to the dense molecular structure of polyester fibers, air circulation is not conducive to the fabric. This makes the woven outer layer 2 have good windproof properties, so that cold air from the outside cannot easily penetrate into the fabric and take away body heat. The support strip surrounds several warming areas 1 4 and several warming areas 2 5 on the surface of the outer layer 2. The warming areas 1 4 and several warming areas 2 5 are arranged alternately. The cross-sectional shape of the warming area 1 4 is a regular hexagon, and the cross-sectional shape of the warming area 2 5 is a square.

[0016] like Figures 1-5 As shown, a fleece block 7 is provided on the side of the insulation area 4 closest to the inner layer 1, and a moisture-wicking block 6 is provided on the side of the insulation area 4 away from the inner layer 1. The cross-sectional shape of the moisture-wicking block 6 and the fleece block 7 are both regular hexagons. The side length of the moisture-wicking block 6 is the same as the side length of the fleece block 7 and is smaller than the side length of the insulation area 4. The moisture-wicking block 6 and the fleece block 7 are arranged opposite each other on both sides of the insulation area 4. Both the moisture-wicking block 6 and the fleece block 7 are formed by tufting moisture-wicking yarn in the breathable area 1 using a tufting process. The thickness of the fleece block 7 is greater than the thickness of the abutment strip 3. The inner layer 1 and the outer layer 2 are hot-pressed together at the support strip by a hot press. The surface of the pressure roller of the hot press is provided with a corresponding design to the abutment strip 3. The raised stripes fix the inner layer 1 and outer layer 2 together, while the insulation area 1 4 is supported by the fleece 7 to form the insulation cavity 1 8. The insulation area 2 5 forms a closed insulation area 2 5. The moisture-wicking yarn is made of polyester fiber and wool fiber blend. Wool fiber has a good heat retention effect. By filling the insulation cavity with wool fiber, the fabric can better retain the body surface temperature when worn. The air in the insulation cavity 2 9 is relatively still. As a poor conductor of heat, air can effectively reduce the temperature transfer on both sides of the insulation cavity 2. At the same time, the insulation cavity 2 9 reduces the overall weight of the fabric, making the fabric lightweight and warm with a comfortable wearing feel.

[0017] like Figure 4 and Figure 5As shown, the inner layer 1 is woven with a plain weave. Both the warp and weft of the inner layer 1 are moisture-wicking yarns. The inner layer 1 is woven on a loom. The moisture-wicking yarns are made of twisted polyester profiled fibers. By shaping the polyester fibers, the porosity and surface area within the fibers are increased, which is conducive to the penetration and diffusion of moisture, thereby improving the hygroscopicity of the polyester fibers. This makes the inner layer 1, woven with moisture-wicking yarns, have a certain degree of hygroscopicity, which can absorb the sweat produced by the skin in time when worn. Wool fibers have stronger hygroscopicity than polyester profiled fibers, so that the hygroscopicity of the moisture-wicking blocks 6 and the fleece blocks 7 is the same and greater than that of the inner layer 1. Therefore, the moisture absorbed in the inner layer 1 can be transferred and dispersed to the moisture-wicking blocks 6 in time through several fleece blocks 7, and can make full contact with the airflow of the outside to quickly dissipate moisture, thereby keeping the inner layer 1 and the skin dry.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
