[0004] Therefore, a new scheme is needed to improve the air permeability of terylene fabric. INVENTION CONTENTS

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A breathable polyester fabric, such as Figure 1 , Figure 2 and Figure 3As shown, the structure includes an outer layer 1 and an inner layer 2, which are sewn together with yarn. The outer layer 1 has several ventilation holes 101 arranged in a matrix array. The inner layer 2 includes a breathable section 3 and a binding section 4. The breathable section 3 has several strands 5, each consisting of several curved sections and several straight sections, alternating between the curved and straight sections. The straight sections of the strands 5 twist the yarn in the inner layer 2, creating several gaps 7. The yarn count of the strands 5 is less than the yarn count of the inner layer 2. The thickness of the breathable section 3 is greater than the thickness of the binding section 4. The breathable section 3 abuts against the outer layer 1 and is located on the outer layer. Several breathable cavities 8 are formed between layer 1 and inner layer 2. Some breathable holes 101 are connected to the breathable cavities 8. By twisting the yarn on the inner layer 2 with twisted yarn 5, several gaps 7 are formed, which increases the overall porosity of the inner layer 2 and improves the overall breathability of the inner layer 2. When the twisted yarn 5 with larger yarn thickness is twisted with the yarn of the inner layer 2, the thickness of the twisted part becomes thicker. After it abuts against the outer layer 1, it forms a breathable cavity 8 inside the fabric. Combined with several breathable holes 101 on the outer layer 1 that are connected to the breathable cavity 8, and several gaps 7 on the inner layer 2, the fabric is guaranteed to have good strength and good breathability.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inner layer 2 is a leno weave, with strand 5 serving as the warp strand. This warp strand consists of two antibacterial yarns, ensuring good yarn strength. The antibacterial yarn is formed by twisting several ramie fibers and several polyester fibers using a twisting machine. Utilizing the excellent antibacterial properties and moisture-wicking breathability of ramie fibers, combined with the good strength of polyester fibers, the antibacterial yarn possesses good yarn strength, antibacterial properties, and breathability. The ground warp and weft of the leno weave use breathable yarns, formed by twisting several bamboo fibers and several polyester profiled fibers using a twisting machine. The polyester profiled fibers have a cross-shaped cross-section, which improves their breathability, and the grooves formed on their surface enhance their moisture absorption. Figure 4As shown, the ground warp and twill warp of the gauze fabric form a twill group, which contains two ground warp and two twill warp. Each time the twill warp changes its position, five ground wefts (five twills) are woven in. In two adjacent twill groups, the twill warp and ground warp twist in symmetrical directions. As the twill warp twists and turns with the ground warp during the weaving process, evenly distributed gaps 7 are formed on the surface of the inner layer 2, which are yarn holes. The ground warp, ground weft, and twill 5 are woven on a rapier loom according to the above method to obtain an inner layer 2 with several gaps 7 on the fabric surface. The part with several gaps 7 is the breathable part 3, and the part without several gaps 7 is the fixed part 4. During the weaving process, the yarn thickness of the twill 5 is greater than that of the ground warp and ground weft. During the twisting process, some ground wefts will come into contact with the twill 5, forming several protrusions 6 on the surface of the inner layer 2.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the outer layer 1 has a perforated weave structure. The yarn used to weave the outer layer 1 is abrasion-resistant yarn. The abrasion-resistant yarn is made by twisting several nylon fibers and several polyester fibers through a twisting machine. Polyester fibers and nylon fibers can provide better strength and abrasion resistance to the abrasion-resistant yarn. The abrasion-resistant yarn is fed into a multi-arm loom and woven into the outer layer 1 with several perforations on the fabric surface according to the weave sequence of the perforated weave structure. The perforations serve as ventilation holes 101.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the twisted thread 5 forms several protrusions 6 on the inner layer 2, which will abut against the outer layer 1 when the inner layer 2 and the outer layer 1 are sewn together, and form several breathable cavities 8 between the inner layer 2 and the outer layer 1. The density of the breathable holes 101 on the outer layer 1 is greater than the density of the gaps 7 on the inner layer 2. The horizontal cross-sectional size of the breathable holes 101 is smaller than the horizontal cross-sectional size of the gaps 7. The larger gaps 7 are used to transport more heat generated by the skin into the breathable cavities 8, and through the smaller but more numerous breathable holes 101, it is evenly transported to the outside of the fabric, improving the overall breathability of the fabric.

[0023] After obtaining the inner layer 2 and outer layer 1 by a loom, the inner layer 2 and outer layer 1 are sewn together using an automatic sewing machine. The sewing position can be the fixed part 4 of the inner layer 2. The inner layer 2 and outer layer 1 are sewn together at the fixed part 4 of the inner layer 2 to complete the processing and production of this breathable polyester 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 by this utility model. 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.
