Description

Technical Field

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

[0002] Fabric is the material used to make clothing. As one of the three essential elements of clothing, fabric not only interprets the style and characteristics of clothing, but also directly affects the color and shape of clothing.

[0003] As the economy develops, people's requirements for clothing fabrics are constantly increasing. Conventional warm fabrics often rely on the traditional practice of thickening or increasing the weaving density, which increases the weight of the clothing and the burden when wearing it.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a warm fabric that improves the warmth of the fabric through a new structural design.

[0006] 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 the inner layer comprises a plurality of heat insulation parts and a plurality of heat storage parts arranged alternately along its length direction, wherein the heat insulation parts are provided with a plurality of raised strips on the side near the outer layer, and a plurality of heat insulation cavities are formed between the plurality of raised strips, the heat insulation parts and the outer layer, wherein the heat storage parts are provided with a plurality of heat storage blocks on the side near the outer layer, and a plurality of heat insulation cavities are formed between the plurality of heat storage blocks, the heat storage parts and the outer layer, wherein the weaving density of the outer layer is greater than that of the inner layer, and a fleece layer is provided on the side of the outer layer away from the inner layer.

[0007] The present invention is further configured such that: a plurality of the convex strips are arranged in an array along the width direction of the heat insulation part, and a plurality of the heat storage blocks are arranged in an array along the length direction of the heat storage part, wherein the side length of the heat storage block is smaller than the distance between adjacent heat insulation parts.

[0008] The present invention is further configured such that: both the inner and outer layers are plain weave, the weaving density of the outer layer is set to 187*176 / cm², and the raised strips are formed by striping the heat insulation yarn through the heat insulation part.

[0009] The present invention is further configured such that: both the warp and weft yarns of the inner layer are made of heat-insulating yarn, and the heat-insulating yarn is made by spirally winding a first strand of yarn around a second strand of yarn, wherein the first strand of yarn is made of twisted wool fibers and the second strand of yarn is made of twisted polyester fibers.

[0010] The present invention is further configured such that the heat storage block is formed by flocking short wool fibers onto the heat storage part.

[0011] The present invention is further configured such that: both the warp and weft yarns of the outer layer are windproof yarns, the windproof yarns are formed by twisting a first strand and a second strand, the diameter of the first strand is larger than the diameter of the second strand, and the pile layer is formed by brushing the first strand.

[0012] The present invention is further configured such that the inner layer and the outer layer are fixed together by sewing together with windproof yarn at several heat storage blocks.

[0013] In summary, this utility model has the following beneficial effects: the fleece layer can block the pores on the outer layer; the tight molecular structure of polyester fibers is not conducive to air circulation, making the outer layer have good windproof effect; air is a poor conductor of heat, and the number of heat insulation chambers increases the content of still air inside the fabric, thereby reducing the temperature transfer between the two sides of the fabric and improving the heat insulation effect; the natural crimp of wool fibers forms an air layer between the fibers, making the inner layer and several heat storage blocks further enhance the heat insulation effect of the fabric, while better locking in the temperature generated by the body surface; the number of heat insulation chambers reduces the overall weight of the fabric, making the clothing lightweight and warm when worn.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example: A thermal fabric, such as Figures 1-2As shown, the system includes an inner layer 1 and an outer layer 2 that are fixedly connected to each other. The inner layer 1 includes several heat insulation parts 3 and several heat storage parts 4 arranged alternately along its length. The heat insulation parts 3 have several elongated protrusions 5 on the side near the outer layer 2, and the length of the protrusions 5 is the same as the length of the heat insulation parts 3. The heat storage parts 4 have several square heat storage blocks 7 on the side near the outer layer 2. The protrusions 5 are arranged in an array along the width direction of the heat insulation parts 3, and the heat storage blocks 7 are arranged in an array along the length direction of the heat storage parts 4. The side length of the heat storage blocks 7 is smaller than the distance between adjacent heat insulation parts 3. The inner layer 1 and the outer layer 2 are located at the heat storage blocks 7. By sewing together windproof yarn 13 using a sewing machine, several heat insulation cavities 16 are formed between several convex strips 5, heat insulation part 3 and outer layer 2, and several heat insulation cavities 28 are formed between several heat storage blocks 7, heat storage part 4 and outer layer 2. Air is a poor conductor of heat. The number of heat insulation cavities 16 and several heat insulation cavities 28 increases the static air content inside the fabric, thereby reducing the temperature transfer between the two sides of the fabric and making it less likely for the internal temperature of the fabric to be lost. At the same time, the number of heat insulation cavities 16 and several heat insulation cavities 28 reduces the overall weight of the fabric, so that the finished garment has a lightweight and warm effect when worn.

[0021] like Figure 1 and Figure 3 As shown, the warp and weft yarns of the inner layer 1 are both set as heat-insulating yarns 10. Several heat-storing parts 4 and several heat-insulating parts 3 are formed integrally by feeding the heat-insulating yarns 10 into the air-jet loom through the inner layer 1 and weaving them in a plain weave. Several raised strips 5 are formed integrally by striping several heat-insulating parts 3 with the heat-insulating yarns 10 using a sewing machine. The wool fibers are cut into short fibers using a cutting machine. Several heat-storing blocks 7 are formed by flocking wool short fibers onto the heat-storing parts 4. The heat-insulating yarns 10 are made by spirally winding a first strand 11 onto a second strand 12 using a ring spinning machine. The first strand 11 is made by twisting wool fibers using a twisting machine. Due to the natural crimp characteristics of wool fibers, an air layer is formed between the fibers, which allows the inner layer 1 and several heat-storing blocks 7 to further enhance the heat insulation effect of the fabric and better lock in the temperature generated by the body surface, thus having a good heat-insulating effect.

[0022] like Figure 1 and Figure 4As shown, both the warp and weft yarns of the outer layer 2 are set as windproof yarns 13. The outer layer 2 is made by feeding the windproof yarns 13 into an air-jet loom and weaving them in a plain weave. The weaving density of the outer layer 2 is greater than that of the inner layer 1. The weaving density of the outer layer 2 is set to 187*176 / cm². By increasing the weaving density of the outer layer 2, the size of the pores formed by weaving is reduced, thereby improving the windproof effect of the outer layer 2. The windproof yarns 13 are formed by twisting a first strand 11 and a second strand 12 using a twisting machine. The second strand 12 is formed by twisting polyester fibers using a twisting machine. Due to its tight molecular structure, polyester fibers will shrink. The internal pores hinder air circulation, thus improving the windproof effect of the outer layer 2. A fleece layer 9 is provided on the side of the outer layer 2 away from the inner layer 1. The fleece layer 9 is integrally formed after the side of the outer layer 2 away from the inner layer 1 is brushed. Since the diameter of the first strand 11 is larger than the diameter of the second strand 12, the brushing roller of the brushing machine will first come into contact with and rub against the first strand 11 during the brushing process, thereby forming the fleece layer 9 of wool fibers. Due to the natural crimping characteristics of wool fibers, the formed fleece layer 9 can block the pores on the outer layer 2, thereby strengthening the windproof effect of the outer layer 2 and effectively blocking the cold air from the outside, thus improving the warmth retention effect.

[0023] like Figures 1-4 As shown, when this type of warm fabric is to be made, a sewing machine is first used to strip the woven inner layer 1 to form several raised strips 5. Then, a cutting machine is used to cut the wool fibers into short fibers. Several heat-retaining blocks 7 are formed on the side of the inner layer 1 with raised strips 5 through a flocking process. A napping machine is used to nap one side of the outer layer 2 to form a pile layer 9. The inner layer 1 is laid flat with the side with the heat-retaining blocks 7 facing up. The outer layer 2 is then placed on top of the inner layer 1 with the side with the pile layer 9 facing up. Finally, the inner layer 1 and the outer layer 2 are sewn together at the locations of the heat-retaining blocks 7 using a sewing machine, thereby forming this type of warm fabric.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. 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.
