Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, to polyester composite fabric with surface perforations. Background Technology

[0002] Polyester fabric is a type of fabric woven from polyester fibers. Due to its tight molecular structure, polyester fibers have high strength and shape retention, making the resulting polyester fabric strong, durable, wrinkle-resistant, and easy to care for. It is widely used in the production of clothing, outdoor products, home decorations, and other products.

[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, causing sweating. The sweat produced cannot be quickly dissipated through the fabric and remains on the skin surface, thus affecting the comfort of wearing the garment.

[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 polyester composite fabric with surface openings.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a polyester composite fabric with surface openings, comprising an inner layer and an outer layer, wherein the inner layer is arrayed with a plurality of first-stage air vents and a plurality of second-stage air vents, and the outer layer is provided with a plurality of moisture-absorbing elements on the side near the inner layer, wherein the side of the moisture-absorbing elements away from the outer layer extends out through a plurality of first-stage air vents, and the inner and outer layers are supported by the plurality of moisture-absorbing elements to form a plurality of breathable cavities, wherein the breathable cavities are interconnected with the plurality of second-stage air vents, and the outer layer is provided with a plurality of third-stage air vents interconnected with the breathable cavities.

[0007] The moisture-absorbing component includes a support portion and several abutting portions. The several support portions are arranged in an array and abut against the inner layer. The several abutting portions extend out from several vent holes.

[0008] The present invention is further configured such that: the inner layer and the outer layer are fixed by sewing together with moisture-wicking yarn, and the side of the inner layer away from the outer layer is sewn to form several grooves.

[0009] The present invention is further configured such that: both the warp and weft yarns of the outer layer are moisture-wicking yarns, which are made of a blend of polyester profiled fibers and flax fibers.

[0010] The present invention is further configured such that both the warp and weft yarns of the inner layer are made of polyester yarn.

[0011] In summary, this utility model has the following beneficial effects: The interconnected air cavities, air vents 2, and air vent 3 improve airflow on both sides of the fabric, thereby enhancing breathability and moisture wicking speed. The inner layer, made of polyester yarn, has high strength and abrasion resistance, making it less prone to wear and longer service life. The contact area between the inner layer and the skin is reduced by the contact parts and grooves, thus improving airflow. The outer layer, made of a blend of polyester profiled fibers and ramie fibers, has strong moisture absorption and rapid moisture wicking properties. The contact parts extending from the inner layer quickly absorb sweat from the skin and transfer it to the outer layer for rapid wicking, thus maintaining the fabric's dryness and comfort when worn.

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

[0018] Example: Polyester composite fabric with surface perforations, such as Figures 1-4As shown, it includes an inner layer 1 and an outer layer 2 that are fixedly connected to each other. The inner layer 1 has several ventilation holes 3 and several ventilation holes 4 arranged in an array. The warp and weft yarns of the inner layer 1 are both made of polyester yarn. The inner layer 1 and its ventilation holes 3 and 4 are formed integrally by feeding the polyester yarn into the loom and weaving it through a perforated structure. The ventilation holes 3 and 4 improve the breathability of the inner layer 1. The polyester yarn is formed by twisting two strands of the first strand by a twisting machine. The first strand is made of polyester profiled fiber. By profiled polyester fiber, the internal voids and surface area of ​​the fiber are increased, thereby improving moisture absorption and breathability. Polyester fiber has high strength and abrasion resistance, so the inner layer 1 made of polyester yarn can not easily wear out when worn while ensuring a certain degree of breathability and moisture absorption, and has a long service life.

[0019] like Figures 1-4 As shown, a number of moisture-absorbing elements 6 are fixedly connected to the side of the outer layer 2 near the inner layer 1. Each moisture-absorbing element 6 includes a support part 601 and a number of arrayed contact parts 602. The contact parts 602 are arrayed and abut against the side of the inner layer 1 near the outer layer 2. The contact parts 602 protrude from a number of ventilation holes 3. The moisture-absorbing elements 6 are formed by tufting yarn made of twisted flax fibers on the outer layer 2. The support part 601 is formed by squeezing the tufted yarn between the inner layer 1 and the outer layer 2. The contact parts 602 are formed by some of the tufted yarn protruding from the ventilation holes 3, so that the contact parts 602 can come into contact with the skin. Flax fibers have good moisture absorption properties, and the contact parts 602 can absorb the sweat produced by the skin in time, thereby enhancing the moisture absorption effect of the fabric.

[0020] like Figure 1 and Figure 4 As shown, both the warp and weft yarns of the outer layer 2 are set as moisture-wicking yarns. The outer layer 2 is made by feeding the moisture-wicking yarn into the loom and weaving it with a plain weave. The moisture-wicking yarn is made by twisting a first strand and a second strand of yarn together using a twisting machine. The second strand is made of flax fiber. Flax fiber has good breathability and quick moisture wicking characteristics, which allows the outer layer 2 to quickly remove moisture from its interior. The hygroscopicity of flax fiber is greater than that of polyester profiled fiber, which allows the moisture absorbed in the inner layer 1 to be transferred to the outer layer 2 through the support part 601 and quickly wicked away, thereby ensuring the dryness of the inner layer 1 and the skin, so that the fabric has a dry and comfortable wearing feel when worn.

[0021] like Figures 1-4As shown, the inner layer 1 and outer layer 2 are sewn together using a sewing machine with moisture-wicking yarn, maintaining a certain tension on the inner layer 1 against the outer layer 2. Simultaneously, the tufted absorbent material 6 has a certain thickness, allowing the inner layer 1 and outer layer 2 to form several breathable cavities 7 supported by the absorbent material 6. Several second-order breathable holes 4 are interconnected with the several breathable cavities 7. The outer layer 2 has several third-order breathable holes 8 drilled using a laser punching machine. These third-order breathable holes 8 are arrayed above the second-order breathable holes 4, allowing them to interconnect with the several breathable cavities 7. The inner layer 1 is located away from... One side of the outer layer 2 is sewn to form several grooves 9, which are interconnected with several ventilation holes 4. The contact area between the inner layer 1 and the skin is reduced by several contact parts 602 and several grooves 9, thereby improving the air circulation between the inner layer 1 and the skin. The air circulation on both sides of the fabric is improved by several interconnected ventilation cavities 7, ventilation holes 4, ventilation holes 8, and grooves 9, which enhances the breathability of the fabric. At the same time, the good air circulation further enhances the moisture evaporation speed of the fabric, making the finished fabric breathable and quick-drying.

[0022] When it is necessary to make the polyester composite fabric with the perforated surface, firstly, use a laser perforation machine to make several ventilation holes 8 on the woven outer layer 2. Then, use a tufting machine to tuft yarn made of twisted flax fibers onto the outer layer 2 to form moisture-absorbing parts 6. Lay the outer layer 2 flat with the side with the moisture-absorbing parts 6 facing up. Cover the outer layer 2 with the woven inner layer 1, so that the part of the moisture-absorbing part 6 that passes through the ventilation holes 4 on the inner layer 1 forms several contact parts 602. The part of the moisture-absorbing part 6 that contacts the inner layer 1 forms a support part 601. Finally, use a sewing machine to sew and fix the area between the adjacent moisture-absorbing parts 6 of the inner layer 1 and the outer layer 2 using a moisture-wicking yarn to form several breathable cavities 7, thereby completing the polyester composite fabric with the perforated surface.

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.
