Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile technology, and more specifically, to breathable chemical fiber fabrics. Background Technology
[0002] Chemical fiber fabric is a common type of yarn fabric, usually woven from chemical fibers such as polyester, nylon, spandex, acrylic, and polypropylene. Due to their tight molecular structure, chemical fibers have good elasticity and abrasion resistance, making the resulting chemical fiber fabric less prone to wrinkling and wear. It is widely used in clothing, bags, home textiles, and outdoor products.
[0003] However, the tight molecular structure of chemical fibers reduces the open space inside the fiber, which is not conducive to the circulation of gas. This makes chemical fibers relatively poorly breathable, and the chemical fiber fabrics made from them are prone to causing a stuffy feeling when worn, affecting the comfort of wearing them.
[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 breathable chemical fiber fabric, which improves the breathability of the chemical fiber fabric through a new structural design.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a breathable chemical fiber fabric, including an inner layer and an outer layer, wherein the inner layer is arrayed with a plurality of breathable grooves, the outer layer is arrayed with a plurality of breathable parts, the breathable parts being interconnected with the breathable grooves, the outer layer having a plurality of moisture-wicking strips arrayed on the side closest to the inner layer, the sidewalls of the moisture-wicking strips forming a breathable space between the inner and outer layers, both the inner and outer layers having a plurality of breathable holes interconnected with the breathable space, and the inner layer having a plurality of protrusions arrayed on the side furthest from the outer layer.
[0007] The present invention is further configured such that: the breathable part and the first breathable groove are arranged opposite to each other, the breathable part has a plurality of second breathable grooves arranged in an array along the width direction of the outer layer, the length of the second breathable groove is the same as the side length of the first breathable groove and they are interconnected.
[0008] The present invention is further configured such that: both the warp and weft yarns of the inner layer are made of abrasion-resistant yarns, the weft yarns of the outer layer are made of moisture-wicking yarns, and the warp yarns of the outer layer are made of abrasion-resistant yarns, wherein the moisture-wicking yarns have greater alkali resistance than the abrasion-resistant yarns.
[0009] The present invention is further configured such that: each of the several breathable grooves is formed by removing part of the warp and weft yarns on the inner layer through an alkaline process of burnout, and each of the several breathable grooves is formed by removing the warp yarns on the breathable part through an alkaline process of burnout.
[0010] The present invention is further configured such that: the wear-resistant yarn is formed by twisting multiple strands of first strand, the first strand being formed by twisting polyester profiled fibers with a Y-shaped cross-section, and the diameter of the wear-resistant yarn is larger than the diameter of the moisture-wicking yarn.
[0011] The present invention is further configured such that: the moisture-wicking yarn is formed by twisting multiple strands of second yarn, the second strand of yarn is formed by twisting cotton fibers, the moisture-wicking yarn has a greater moisture absorption than the abrasion-resistant yarn, and the inner layer and the outer layer are sewn together with abrasion-resistant yarn.
[0012] In summary, this utility model has the following beneficial effects: by shaping the polyester fibers, the internal gaps and surface area of the fibers are increased, giving the inner layer a certain degree of moisture absorption and breathability. Several ventilation grooves enhance the breathability of the inner layer, while several protrusions reduce the contact area between the inner layer and the skin, thereby increasing the gap between the inner layer and the skin and improving the air circulation between them. Several interconnected ventilation spaces and pores, as well as several interconnected ventilation grooves, improve the air circulation on both sides of the fabric, thus enhancing the breathability of the fabric. Cotton fibers have stronger moisture absorption and dissipation properties than shaped polyester fibers, allowing the moisture absorbed in the inner layer to be quickly transferred to the outer layer and dissipated, thereby maintaining the dryness of the inner layer and the skin.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] Example: Breathable synthetic fiber fabric, such as Figure 1 and Figure 4 As shown, it includes an inner layer 1 and an outer layer 2 that are fixedly connected to each other. The warp and weft yarns of the inner layer 1 are both made of abrasion-resistant yarn 10. The inner layer 1 is made by feeding the abrasion-resistant yarn 10 into an air-jet loom and weaving it with a plain weave. The abrasion-resistant yarn 10 is formed by twisting three strands of the first strand 12 by a twisting machine. The first strand 12 is formed by twisting polyester profiled fibers with a Y-shaped cross-section by a twisting machine. The polyester profiled fibers with a Y-shaped cross-section are spun by a spinneret. By shaping the polyester fibers, the internal porosity and surface area of the fibers are increased, thereby improving the breathability and moisture absorption of the polyester fibers. This makes the inner layer 1 have a certain degree of breathability and moisture absorption. The high elasticity and abrasion resistance of the polyester profiled fibers make the inner layer 1 have good shape retention and is not easy to wear and break.
[0021] like Figures 1-5 As shown, the inner layer 1 has several air-permeable grooves 3 arranged in an array. The cross-sectional shape of the air-permeable grooves 3 is square. Polyester profiled fibers have poor alkali resistance and will hydrolyze in alkaline solutions. The air-permeable grooves 3 are formed by removing some of the warp and weft yarns on the inner layer 1 through an alkaline process of burnout. Due to the interweaving of the warp and weft yarns, the inner layer 1 is not easy to loosen after removing some of the warp and weft yarns, which can ensure the stability of the structure. The air permeability of the inner layer 1 is improved by the air-permeable grooves 3. The outer layer 2 has several moisture-guiding strips 5 on the side near the inner layer 1. The length of the moisture-guiding strips 5 is the same as the width of the outer layer 2. The weft yarn of the outer layer 2 is set as a moisture-wicking yarn 11, and the warp yarn of the outer layer 2 is set as abrasion-resistant yarn 10. The outer layer 2 and its several moisture-wicking strips 5 are fed into the air-jet loom through the abrasion-resistant yarn 10 and the moisture-wicking yarn 11 and are formed as a whole by the ribbed weaving method. The inner layer 1 and the outer layer 2 are sewn together by a sewing machine using abrasion-resistant yarn 10, so that the side of the inner layer 1 away from the outer layer 2 is supported by several moisture-wicking strips 5 to form several protrusions 8. The several protrusions 8 reduce the contact area between the inner layer 1 and the skin, thereby increasing the gap between the inner layer 1 and the skin and improving the air circulation effect between the inner layer 1 and the skin.
[0022] like Figures 1-5As shown, the outer layer 2 is arrayed with several square air-permeable sections 4, each with several elongated air-permeable grooves 9. The alkali resistance of the moisture-wicking yarn 11 is greater than that of the abrasion-resistant yarn 10. The air-permeable grooves 9 are formed by removing the warp yarns from the air-permeable sections 4 through an alkali-dissolving process. The air-permeable grooves 9 are arrayed along the width direction of the outer layer 2. The air-permeable sections 4 and air-permeable grooves 3 are positioned opposite each other. The length of the air-permeable grooves 9 is the same as the side length of the air-permeable grooves 3, so that the air-permeable grooves 9 and the air-permeable grooves 3 are interconnected. The sidewall of the moisture-wicking strip 5 forms a gap between the inner layer 1 and the outer layer 2. The cross-section of the breathable space 6 is triangular. Both the inner layer 1 and the outer layer 2 have a number of arrayed breathable holes 7. The breathable holes 7 on the inner layer 1 and the outer layer 2 are symmetrically arranged and are all connected to the breathable space 6. The breathable holes 7 on the inner layer 1 and the outer layer 2 are formed by simultaneously penetrating the inner layer 1 and the outer layer 2 with a laser punch. The air circulation effect on both sides of the fabric is improved by the number of interconnected breathable spaces 6 and breathable holes 7, as well as the number of interconnected breathable grooves 1 and 2 9, thereby enhancing the breathability of the fabric.
[0023] like Figure 1 , Figure 4 and Figure 5 As shown, the moisture-wicking yarn 11 is formed by twisting two strands of second yarn 13 together using a twisting machine. The second yarn 13 is formed by twisting cotton fibers together using a twisting machine. Cotton fibers have many pores inside, which provide excellent moisture absorption and air circulation, allowing them to quickly disperse the absorbed moisture. Therefore, cotton fibers have stronger moisture absorption and dissipation properties than polyester profiled fibers, making the moisture absorption of the outer layer 2 greater than that of the inner layer 1. The moisture absorbed in the inner layer 1 can be quickly dissipated in the outer layer 2 through several moisture-wicking strips 5 and the part that abuts against the outer layer 2, thus keeping the inner layer 1 and the skin dry. The diameter of the abrasion-resistant yarn 10 is larger than that of the moisture-wicking yarn 11, causing the polyester profiled fibers in the outer layer 2 to come into contact with and rub against the external object first, thereby reducing the wear of the cotton fibers and improving the abrasion resistance of the fabric.
[0024] like Figures 1-5 As shown, when it is necessary to make this breathable chemical fiber fabric, first lay the woven inner layer 1 flat, then place the woven outer layer 2 with the side having the moisture-wicking strip 5 facing down and cover the inner layer 1. Use a sewing machine to sew the inner layer 1 and outer layer 2 together with abrasion-resistant yarn 10. The area between the moisture-wicking strip 5 and the sewn area of the inner layer 1 and outer layer 2 is cut with a laser cutting machine to create several ventilation holes 7. The area where the inner layer 1 and outer layer 2 meet is simultaneously treated with a burnout process to remove some of the warp yarns on the outer layer 2 and some of the warp and weft yarns on the inner layer 1, thereby forming several ventilation grooves 9 on the outer layer 2 and several ventilation grooves 3 on the inner layer 1, thus completing the production of the breathable chemical fiber 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.
