Description

Technical Field

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

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

[0003] Patent document CN220374047U discloses a windproof clothing fabric, including a first fabric layer, a breathable layer on one side of the first fabric layer, an antistatic layer on the side of the breathable layer away from the first fabric layer, a skin-friendly layer on the side of the antistatic layer away from the breathable layer, a second fabric layer on the side of the first fabric layer away from the breathable layer, an antibacterial layer on the side of the second fabric layer away from the first fabric layer, an elastic protective layer on the side of the antibacterial layer away from the second fabric layer, and a windproof layer on the side of the elastic protective layer away from the antibacterial layer.

[0004] The above solution improves the performance of the finished fabric by stacking eight functional fabric layers. However, stacking too many fabric layers will make the finished fabric thicker and heavier. Clothing made from this fabric will be bulky and restrict movement, affecting the comfort of wearing it.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a windproof fabric.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a windproof fabric, comprising an inner layer and an outer layer, wherein the outer layer has several recesses and several protrusions woven on both sides, a windproof layer is covered on the side of the outer layer near the inner layer, the gap between the windproof layer and the recesses forms a windproof cavity, a number of heat storage blocks are arranged in an array on the side of the inner layer near the outer layer, the inner layer and the outer layer are supported by the number of heat storage blocks to form a heat storage cavity, and a number of abutment strips are provided on the side of the inner layer away from the outer layer.

[0008] The present invention is further configured such that: a plurality of the aforementioned recesses are arranged on one side of the outer layer near the inner layer, and the recesses and protrusions have the same cross-sectional shape and are correspondingly arranged on both sides of the outer layer.

[0009] The present invention is further configured such that: the outer layer is woven with a plain jacquard weave, both the warp and weft yarns of the outer layer are windproof yarns, and the warp floats of the outer layer are warm yarns.

[0010] The present invention is further configured such that: the windproof layer is a polyurethane film, the inner layer is coated with a polyurethane adhesive layer on the side near the outer layer, and the heat storage block is formed by flocking short wool fibers onto the polyurethane adhesive layer.

[0011] The present invention is further configured such that a plurality of the contact strips are arranged in an array along the length direction of the inner layer below a plurality of heat storage blocks.

[0012] The present invention is further configured such that: the weave structure of the inner layer is a raised stripe structure, and both the warp and weft yarns of the inner layer are made of heat-insulating yarns.

[0013] The present invention is further configured such that: the warm yarn is made by spirally winding a first strand of yarn around a second strand of yarn, the first strand of yarn being made of twisted wool fibers, the second strand of yarn being made of twisted nylon fibers, and the windproof yarn being made by twisting multiple strands of the second strand of yarn.

[0014] In summary, this utility model has the following beneficial effects: By adding a windproof layer between the inner and outer layers, the external airflow can be effectively restricted from penetrating the fabric. Due to its high density, nylon fiber has good windproof performance, so the outer layer made of nylon fiber with a high weave density has a good windproof effect. The presence of several windproof chambers will compress the airflow entering from the outside, change the direction of airflow, thereby reducing the wind speed and reducing the impact force on the windproof layer, making it difficult for external airflow to penetrate the windproof layer, further enhancing the windproof performance. The presence of heat storage chambers forms a static air layer between the inner layer and the windproof layer. Air, as a poor conductor of heat, can effectively reduce heat transfer. Due to its natural crimped special structure, wool fiber forms dense pores, so that the several heat storage blocks can better lock in the temperature generated by the body surface, thereby obtaining good warmth retention.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: A windproof fabric, such as Figures 1-5 As shown, it includes an inner layer 1 and an outer layer 2. The outer layer 2 has several recesses 3 and several protrusions 4 woven into its two sides. An array of recesses 3 is arranged on the side of the outer layer 2 closest to the inner layer 1. Both the warp and weft yarns of the outer layer 2 are windproof yarns 11, and the warp floats of the outer layer 2 are warming yarns 12. The outer layer 2 is made by feeding the windproof yarns 11 along the warp and weft directions and the warming yarns 12 along the warp direction into a multi-arm loom and weaving them using a plain weave jacquard structure. The protrusions 4 are integrally formed on the outer layer 2 by several arranged warp floats. Several depressions 3 are integrally formed on the outer layer 2 due to the lack of thickness of the float thread, so that the cross-sectional shape of the depressions 3 and the protrusions 4 are the same and are correspondingly set on both sides of the outer layer 2. The windproof yarn 11 is formed by twisting three strands of the second strand 15 by a twisting machine. The second strand 15 is formed by twisting nylon fibers by a twisting machine. The large molecular density of nylon fibers can effectively block air penetration. The weaving density of the outer layer 2 is set to 185*173 / 10cm², so that the outer layer 2 made of nylon fibers with a high weaving density has good windproof performance.

[0019] like Figures 1-3 As shown, a windproof layer 5 is applied to the side of the outer layer 2 near the inner layer 1 by a heat transfer machine. This windproof layer 5 is made of polyurethane film and has good windproof performance. By adding a windproof layer 5 between the inner layer 1 and the outer layer 2, the external airflow can be effectively restricted from penetrating the fabric. The gap between the windproof layer 5 and several recesses 3 forms several windproof cavities 6. The presence of several windproof cavities 6 will compress the airflow entering from the outside, change the direction of airflow, thereby reducing the wind speed and reducing the impact force on the windproof layer 5, making it difficult for the external airflow to penetrate the windproof layer 5, and further enhancing the windproof performance. Several heat storage blocks 7 are arrayed on the side of the inner layer 1 near the outer layer 2. The inner layer 1 and the outer layer 2 are supported by several heat storage blocks 7 to form a heat storage cavity 8 with a grid-like cross section. The presence of the heat storage cavity 8 makes a static air layer formed between the inner layer 1 and the windproof layer 5. Air, as a poor conductor of heat, can effectively reduce the transfer of heat, making it difficult for the temperature generated on the body surface to be lost.

[0020] like Figures 1-5As shown, the inner layer 1, near the outer layer 2, is coated with a polyurethane adhesive layer 13 using an array of coating machines. The heat storage blocks 7 are formed by flocking short wool fibers onto the polyurethane adhesive layer 13. Due to their naturally crimped structure, wool fibers form dense pores, allowing the heat storage blocks 7 to better retain the temperature generated on the body surface, thus achieving good warmth retention. The inner layer 1, away from the outer layer 2, has several abutment strips 9. Both the warp and weft yarns of the inner layer 1 are set as heat-insulating yarns 12. The inner layer 1 and its several abutment strips 9 are integrally formed by feeding the heat-insulating yarns 12 into an air-jet loom and weaving them using a raised strip weave. The heat-insulating yarns 12 are made by spirally winding a first strand 14 onto a second strand 15 using a ring spinning machine. The first strand 14 is twisted by a twisting machine to twist the wool fibers. The excellent moisture absorption properties of wool fibers allow them to absorb moisture from the skin or surrounding air, maintaining a certain level of moisture on the surface of the insulating yarn 12. Several raised strips reduce the contact area between the inner layer 1 and the skin, thus reducing static electricity generation during wear. Simultaneously, the soft and skin-friendly nature of wool fibers provides a comfortable wearing experience. Several abutment strips 9 are arrayed along the length of the inner layer 1 below several heat storage blocks 7. Wool fibers have strong moisture absorption properties, absorbing water molecules from the skin or surrounding air. During moisture absorption, the kinetic energy of the water molecules decreases and is converted into heat energy, giving the wool fibers a moisture-absorbing and heat-generating effect. This allows the inner layer 1 and the heat storage blocks 7 to dissipate heat during wear, providing a warm wearing experience.

[0021] When this type of windproof fabric is to be made, a polyurethane adhesive layer 13 is applied in an array using a glue applicator to the side of the inner layer 1 away from the raised strip. Then, short wool fibers are flocked onto the polyurethane adhesive layer 13 to form a heat storage block 7. The flocked inner layer 1 is then transported into a drying chamber, where the polyurethane adhesive layer 13 is shaped into a thin film and fixes the heat storage block 7. A heat transfer machine is used to apply a layer of polyurethane film to the side of the woven outer layer 2 with the recess 3. The inner layer 1 is laid flat with the side with the heat storage block 7 facing up. The outer layer 2 is then placed on top of the inner layer 1 with the side with the recess 3 facing down. Finally, the inner layer 1 and the outer layer 2 are sewn together using a sewing machine to complete the production of this type of windproof fabric.

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.
