[0003] Polyester fiber has good light shielding performance, so people will use clothing made of polyester fabric when doing outdoor sports. The air permeability of polyester fiber itself is poor, so it is necessary to reduce the knitting density of yarns to increase the pores of the fabric and thus increase its air permeability. However, such a design will increase the light passing through the fabric, thereby reducing the light shielding effect of the fabric itself. Therefore, a new method needs to be proposed to solve the problem that polyester fabric cannot balance air permeability and light shielding property. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0019] The present utility model: a breathable polyester base fabric, as Figure 1 、 Figure 2As shown in the figure, it includes an inner layer 1 and an outer layer 2 that are fixedly connected to each other. The knitting density of the yarn in the inner layer 1 is small and the voids are large, increasing the air permeability of the fabric. On one side of the outer layer 2 close to the inner layer 1, a number of air-permeable parts 3 are fixedly connected. The air-permeable parts 3 are evenly distributed on the outer layer 2. The outer layer 2 is provided with a number of air-permeable grooves 4 at the same relative positions as the air-permeable parts 3. The air-permeable grooves 4 can increase the area of contact between the outer layer 2 and the air, enhancing the air circulation effect on the surface of the outer layer 2. On the side wall of the air-permeable groove 4, two air-permeable holes 5 penetrating the thickness direction of the air-permeable part 3 are provided. The outside air can contact the inner layer 1 through the air-permeable holes 5, increasing the circulation of the inner layer 1 and the outside air and improving the air permeability effect of the fabric. On one side of the inner layer 1 close to the outer layer 2, a number of grooves 6 are provided at the same relative positions as the air-permeable parts 3. During use, the air-permeable parts 3 extend into the grooves 6, and there is a gap between the air-permeable parts 3 and the inner wall of the grooves 6. The space formed between the bottom surface of the grooves 6 and the air-permeable parts 3 improves the air circulation between the inner layer 1 and the outer layer 2, increasing the air permeability effect of the fabric.

[0020] As Figure 2 , Figure 3 shown in the figure, the cross-sectional area of the air-permeable part 3 is arc-shaped, increasing the space for air circulation between the air-permeable part 3 and the groove 6. On one side of the air-permeable part 3 close to the inner layer 1, a number of sunscreen fluff 7 are fixedly connected. The sunscreen fluff 7 is misaligned with the air-permeable holes 5. The sunscreen fluff 7 can absorb the light entering from the air-permeable holes 5, reducing the probability of light irradiating on the inner layer 1 and improving the light-shielding effect of the fabric.

[0021] As Figure 2 , Figure 3 shown in the figure, the inner layer 1 and the groove 6 are integrally formed. The inner layer 1 is set as a honeycomb structure, and the groove 6 is the concave part of the honeycomb structure. The honeycomb structure has good porosity and air permeability and is soft and comfortable. Using the honeycomb structure can improve the air permeability of the inner layer 1, and the integrally formed inner layer 1 makes the structure of the fabric more stable. The distance between the side wall of the groove 6 and the air-permeable hole 5 is greater than zero. Since the groove 6 has a slope, it may block the air-permeable hole 5, affecting the air circulation effect between the outside air and the inner layer 1.

[0022] As Figure 1 , Figure 4 shown in the figure, the inner layer 1 is woven by air-permeable yarn 8. The air-permeable yarn 8 includes air-permeable core yarn one 9 and air-permeable core yarn two 10. The air-permeable core yarn one 9 and the air-permeable core yarn two 10 are twisted by a twisting machine to form the air-permeable yarn 8. The air-permeable core yarn one 9 is twisted by a twisting machine from polyester profiled fibers with a Y-shaped cross-section. The setting of the polyester profiled fibers forms a channel for the outside air to flow through inside the air-permeable yarn 8, enhancing the air permeability and comfort performance during use. The air-permeable core yarn two 10 is twisted by a twisting machine from bamboo original fibers. The bamboo original fibers have good air permeability effect, which can further optimize the air permeability of the inner layer 1. At the same time, the bamboo original fibers can absorb the light penetrating through the outer layer 2 from the outside, improving the light-shielding performance of the fabric.

[0023] As Figure 2 , Figure 5 shown, the outer layer 2 and the breathable member 3 are woven by the light-shielding yarn 11. The light-shielding yarn 11 includes a first light-shielding core yarn 12 and a second light-shielding core yarn 13. The first light-shielding core yarn 12 is twisted by a twisting machine from polyester fibers. The good light resistance of the polyester fibers can enhance the light resistance and sun protection performance of the fabric. The second light-shielding core yarn 13 is twisted by a twisting machine from acrylic fibers. The acrylic fibers have good light resistance, and the structural strength will not decrease even when the acrylic fibers are in contact with light for a long time. The acrylic fibers enhance the light resistance and durability of the fabric. The sunscreen fluff 7 is made of bamboo original fibers. The bamboo original fibers contain sodium copper chlorophyll which can absorb and reflect the ultraviolet rays in the light irradiated from the outside into the space between the light-shielding member and the groove 6, improving the sun protection effect of the fabric.

[0024] As Figures 1 - 5 shown, when making this fabric, the light-shielding yarn 11 is put into a loom to be woven into the outer layer 2. A plurality of ventilation holes 5 are formed in the outer layer 2 by a laser drilling machine, and then a plurality of breathable members 3 recessed inwardly toward the inner layer 1 are formed by hot pressing. The hot pressing makes a plurality of ventilation grooves 4 corresponding to the breathable members 3 formed on the surface of the outer layer 2. The ventilation holes 5 are located on the side walls of the ventilation grooves 4. On the side of the breathable member 3 close to the inner layer 1, the bamboo original fibers are fixed on the outer wall of the breathable member 3 by electrostatic flocking through a flocking machine. The ventilation yarn 8 is put into a loom and the inner layer 1 is formed by the honeycomb weave. The honeycomb weave of the inner layer 1 forms grooves 6 corresponding to the breathable members 3 one by one. Finally, the inner layer 1 and the outer layer 2 are sewn together by a sewing machine.

[0025] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as within the protection scope of the present invention.
