Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, to breathable polyester 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 abrasion resistance and shape retention, making the resulting polyester fabric strong, durable, wrinkle-resistant, and easy to care for. It is widely used in clothing, home furnishings, outdoor products, and other fields.

[0003] However, the tight molecular structure of polyester fibers reduces the pores and surface area within the fibers, which is not conducive to air circulation and moisture penetration and diffusion. This makes clothing made of polyester fabrics prone to feeling stuffy and hot when worn. The sweat produced cannot be quickly dissipated through the fabric and remains on the skin surface, causing the clothing to stick to the skin due to the sweat, thus reducing the comfort of 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 breathable polyester fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a breathable polyester fabric, comprising an inner layer and an outer layer, wherein the inner layer comprises a plurality of moisture-absorbing parts and a plurality of breathable parts arranged alternately along its length direction, wherein the moisture-absorbing parts are arranged in an array with a plurality of moisture-guiding blocks and a plurality of grooves I on the side of the moisture-absorbing parts near the outer layer, and the moisture-absorbing parts are arranged in an array with a plurality of moisture-absorbing blocks and a plurality of grooves II on the side of the moisture-absorbing parts away from the outer layer, wherein the gaps between the inner layer, the outer layer, the plurality of moisture-guiding blocks and the plurality of grooves I form a ventilation space, wherein the array of breathable parts is provided with a plurality of ventilation holes communicating with the ventilation space, and wherein the outer layer is provided with a plurality of ventilation grooves communicating with the ventilation space.

[0007] The present invention is further configured such that: the moisture-guiding block, groove one, moisture-absorbing block and groove two have the same cross-sectional shape; a plurality of the moisture-guiding blocks and a plurality of groove one are staggered along the width direction of the inner layer; and a plurality of the air-permeable groove array is arranged above a plurality of air-permeable parts.

[0008] The present invention is further configured such that: the moisture-wicking block and the second groove are arranged vertically and vertically, the first groove and the moisture-absorbing block are arranged vertically and vertically, and the inner layer and the outer layer are located at the moisture-wicking block and the second groove and are fixed by sewing together with moisture-absorbing yarn.

[0009] The present invention is further configured such that: the warp yarn of the inner layer is a moisture-absorbing yarn, the weft yarn of the inner layer is a breathable yarn, and the inner layer is made by alternating weave of plain ground small jacquard and openwork structures, wherein the pattern of the plain ground small jacquard is composed of warp floats.

[0010] The present invention is further configured such that: the moisture-absorbing yarn is formed by twisting multiple strands of first strand, and the first strand is a modified polyester profiled fiber with a trilobal cross-section.

[0011] The present invention is further configured such that: both the warp and weft yarns of the outer layer are made of breathable yarns, the breathable yarns are made by twisting a first strand and a second strand, the second strand is made of polyester profiled fiber with a hexagonal cross-section, and the count of the first strand is greater than the count of the second strand.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example: Breathable polyester fabric, such as Figures 1-4 As shown, the structure includes an inner layer 1 and an outer layer 2 that are fixedly connected to each other. The inner layer 1 includes a plurality of moisture-absorbing parts 101 and a plurality of breathable parts 102 arranged alternately along its length. The breathable parts 102 have a plurality of air vents 8 arranged in an array, which improves the breathability of the breathable parts 102 and enhances the air circulation on both sides of the breathable parts 102. The moisture-absorbing parts 101 have a plurality of moisture-guiding blocks 3 and a plurality of grooves 4 arranged in an array on the side near the outer layer 2, and a plurality of moisture-absorbing blocks 5 and a plurality of grooves 6 arranged in an array on the side away from the outer layer 2. The plurality of moisture-guiding blocks 3, grooves 4, moisture-absorbing blocks 5, and grooves 6 increase the surface area of ​​the moisture-absorbing parts 101, thereby improving the moisture dissipation speed of the moisture-absorbing parts 101. The sides of the moisture-guiding blocks 3 away from the moisture-absorbing parts 101 are all connected to the outer layer 2. With the inner layer 1 and outer layer 2 supported by several moisture-wicking blocks 3, a ventilation space 7 is formed between the inner layer 1, outer layer 2, several moisture-wicking blocks 3 and several grooves 4. Several ventilation holes 8 are interconnected with the ventilation space 7. Several ventilation grooves 9 are opened by a laser punching machine on the outer layer 2. Several ventilation grooves 9 are arrayed above several ventilation parts 102, so that several ventilation grooves 9 are interconnected with the ventilation space 7. The interconnected ventilation space 7, several ventilation holes 8 and several ventilation grooves 9 improve the air circulation effect on both sides of the fabric. Several moisture-absorbing blocks 5 reduce the contact area between the inner layer 1 and the skin, thereby improving the air circulation effect between the inner layer 1 and the skin, thus obtaining good breathability. At the same time, the good air circulation effect accelerates the moisture dissipation speed of the fabric.

[0023] like Figures 1-6As shown, the moisture-wicking block 3, groove one 4, moisture-absorbing block 5, and groove two 6 have the same cross-sectional shape. Several moisture-wicking blocks 3 and several grooves one 4 are staggered along the width direction of the inner layer 1. Moisture-wicking blocks 3 and groove two 6 are arranged vertically correspondingly, and groove one 4 and moisture-absorbing block 5 are arranged vertically correspondingly. The warp yarn of the inner layer 1 is set as moisture-absorbing yarn 10, and the weft yarn of the inner layer 1 is set as breathable yarn 12. The inner layer 1 is made by feeding the moisture-absorbing yarn 10 and breathable yarn 12 into a loom and weaving them alternately using a plain weave small jacquard structure and a perforated structure. The pattern of the plain weave small jacquard structure is composed of warp floats. Several moisture-wicking blocks 3 and... Each of the several moisture-absorbing blocks 5 is composed of several parallel warp floats. The float length of the warp floats is set to four weaving points. The moisture-absorbing part 101 is respectively opposite to the moisture-absorbing block 5 and the moisture-guiding block 3. Due to the lack of the thickness of several warp floats, it is concave to form several grooves 1 4 and several grooves 2 6. Thus, the moisture-absorbing part 101 and the several moisture-guiding blocks 3, grooves 1 4 and several moisture-absorbing blocks 5, grooves 2 6 formed on its two sides are all integrally formed on the inner layer 1 by the weaving method of plain small jacquard weave. The breathable part 102 and the several breathable holes 8 are all integrally formed on the inner layer 1 by the weaving method of perforated weave.

[0024] like Figures 1-5 As shown, the inner layer 1 and outer layer 2 are sewn together by a sewing machine using moisture-absorbing yarn 10 at several moisture-wicking blocks 3 and several grooves 6. The moisture-absorbing yarn 10 is formed by twisting three strands of first strand 11 by a twisting machine. The first strand 11 is a modified polyester profile fiber with a trilobal cross-section. By modifying the polyester fiber, the porosity and surface area inside the fiber are increased, thereby improving air circulation and moisture penetration and diffusion, and improving moisture absorption and breathability. The modified polyester profile yarn with a trilobal cross-section is formed by adding carboxyl hydrophilic monomers to polyester raw materials and then spinning it on a spinneret with trilobal openings. The mixing ratio of polyester raw materials and hydrophilic monomers is set to 8:2. The modified polyester profile yarn made by adding hydrophilic monomers has good hydrophilicity, which further improves the moisture absorption effect, so that the several moisture-absorbing blocks 5 formed by several moisture-absorbing yarns 10 can quickly absorb the sweat produced by the skin when in contact with the skin.

[0025] like Figures 1-7As shown, both the warp and weft yarns of the outer layer 2 are made of breathable yarn 12. The outer layer 2 is made by feeding the breathable yarn 12 into the loom and weaving it using a plain weave. Because the warp and weft yarns in the outer layer 2 are interwoven, the outer layer 2 is not easy to loosen after the ventilation grooves 9 are opened. At the same time, the laser cutting of the outer layer 2 generates a high temperature, which can be used to seal the cut edges of the outer layer 2, thereby maintaining the structural stability of the outer layer 2. The breathable yarn 12 is made by twisting a first strand 11 and a second strand 13 using an "S" twisting method. The second strand 13 is made of polyester profiled fiber with a hexagonal cross-section, so that the second strand... 13 has good breathability. Because the count of the first strand 11 is greater than that of the second strand 13, the diameter of the first strand 11 is smaller than that of the second strand 13. Therefore, the surface of the breathable yarn 12 formed by twisting is continuously uneven, which makes a large number of pores formed in the outer layer 2 formed by the interweaving of the breathable yarn 12, thereby enhancing the breathability of the outer layer 2. The moisture absorbed in the inner layer 1 can be transferred to the outer layer 2 through several moisture-wicking blocks 3. The outer layer 2 can quickly dissipate moisture through full contact with the outside air, thereby keeping the inner layer 1 and the skin dry. This makes the fabric less likely to stick to the skin due to sweat, and provides a comfortable and breathable wearing experience.

[0026] like Figures 1-7 As shown, when this breathable polyester fabric needs to be made, a first strand 11 and a second strand 13 are twisted together using a twisting machine to form a breathable yarn 12. The breathable yarn 12 is then fed into the loom along the warp and weft directions to form the outer layer 2. Three strands of the first strand 11 are twisted together using a twisting machine to form a moisture-absorbing yarn 10. The moisture-absorbing yarn 10 and the breathable yarn 12 are then fed into the loom along the warp and weft directions respectively to form the outer layer 2. The outer layer 2 is then woven together as a single unit. Several moisture-wicking blocks 3, groove 1 4, moisture-absorbing blocks 5, groove 2 6, and ventilation holes 8 are formed. Several ventilation grooves 9 are opened on the outer layer 2 using a laser cutting machine. After the outer layer 2 is laid flat, the inner layer 1 is placed with the side of the moisture-wicking blocks 3 facing down and covering the outer layer 2. The inner layer 1 is moved so that the ventilation holes 8 are above the ventilation grooves 9. Finally, the inner layer 1 and the outer layer 2 are sewn together with moisture-absorbing yarn 10 using a sewing machine to complete the production of the breathable polyester fabric.
