[0002] Polyester is a fiber with good elasticity and high strength. The fabric is crisp and has good shape retention. It is a fiber with wide applications and high consumption.

[0003] Polyester fabric is formed by weaving polyester composite yarns in warp and weft. Utilizing the characteristics of polyester fibers, polyester fabric is often used to make clothing and other daily necessities.

[0004] In order to ensure the breathability of fabrics during use, clothing fabrics are often made thinner or have more pores opened on the fabrics. When people are outdoors, the outside sunlight can easily pass through the fabrics and shine on the user's body surface. In order to reduce the light transmittance of the fabric, the weaving density of the fabric is increased to reduce the amount of pores formed when the fabric is weaved, which in turn affects the air circulation on both sides of the fabric. Therefore, a structure is set to solve the problem that some fabrics cannot take into account both sun protection and breathability. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] This kind of sun-proof polyester fabric, such as Figure 1 and Figure 2As shown, it includes a base layer 1. The single-layer fabric accelerates the flow and exchange speed of air on both sides of the fabric. A plurality of ventilation grooves 2 are opened along the thickness direction of the base layer 1 by a laser cutting machine. The setting of the ventilation grooves 2 provides a channel for the outside air to stably enter the inside of the fabric, thereby ensuring the breathability and comfort of the structure when in use. Both sides of the base layer 1 are sewn with shielding pieces 3 with the same relative position as the ventilation grooves 2 by a sewing machine. The setting of the shielding pieces 3 increases the thickness of some positions of the base layer 1, so that the light can be better absorbed and reflected inside the fabric, reducing the amount of light that passes through the fabric and contacts the user's body surface, and the thickness of the shielding pieces 3 is less than the thickness of the base layer 1, so that the fabric reduces the amount of light that passes through the fabric while accelerating the circulation speed of air on both sides of the shielding pieces 3. On the other hand, the shielding pieces 3 reduce the contact area between the base layer 1 and the user's body surface, so that there is a channel for the outside air to flow between the base layer 1 and the user's body surface, thereby ensuring the sun-proof and breathable properties of the structure when in use.

[0020] like Figure 1 and Figure 2 As shown, shielding piece 1 4 and shielding piece 2 5 are respectively bonded to adjacent sides of adjacent shielding pieces 3, and the cross-sectional area of ​​shielding piece 1 4 is smaller than the cross-sectional area of ​​shielding piece 2 5, thereby increasing the outside air flowing through shielding piece 2 5, and the sum of the thickness of shielding piece 1 4 and shielding piece 2 5 is greater than the depth of the breathable groove 2, so that the shielding piece 3 can form an arch under the action of shielding piece 1 4 and shielding piece 2 5, so that the outside air can enter the interior of the fabric from the distance between the shielding piece 3 and the base layer 1, and pass through the breathable groove 2 to contact the user's body surface, thereby enhancing the breathable comfort of the structure when used.

[0021] like Figure 1 and Figure 2 As shown, the light absorption of shielding piece 2 5 is greater than that of shielding piece 1 4, and a plurality of divergent fleeces 6 are integrally formed on the outer peripheral wall of shielding piece 4. Shielding piece 4 is located on the side of the fabric close to the outside air. Therefore, the light entering the interior of the fabric along the space between the shielding piece 3 and the base layer 1 can first contact with shielding piece 4. The provision of divergent fleece 6 increases the surface roughness of shielding piece 4, so that the external light can be better diverged. Since shielding piece 2 5 has good light absorption, shielding piece 2 5 can stably absorb the remaining light entering the breathable groove 2, and enhance the sun protection of the structure when used by reducing the amount of light passing through the shielding piece 3 and contacting the user's body surface.

[0022] like Figure 1 and Figure 2As shown, shielding piece 2 5 abuts against the inner wall of the ventilation groove 2, so that there is a ventilation channel between adjacent shielding pieces 2 5 arranged along the length direction of the base layer 1, so that the air entering the interior of the fabric can flow in the fabric along the ventilation channel, so that the fabric can ensure good sun protection while taking into account the breathability. Shielding piece 1 4 and shielding piece 2 5 are both set to be spherical. The spherical setting ensures that shielding piece 1 4 and shielding piece 2 5 stably support the shielding sheet 3 while increasing the outside air flowing along the surface of shielding piece 1 4 and shielding piece 2 5, thereby ensuring the sun protection and breathability of the structure when it is used.

[0023] like Figure 2 As shown, shielding member 1 4 is formed by kneading polyester shaped fibers with a cross-sectional shape of Y, the polyester shaped fibers are put into a cutting machine to cut into staple fibers, the cut polyester shaped fibers are put into a cotton blending machine to weave into polyester yarns, and then the polyester yarns are put into an automatic pilling machine to knead to form shielding member 1 4. Since the polyester yarn used to process shielding member 1 4 is formed by blending staple yarns with cotton, divergent fleece 6 can be naturally formed on the surface of shielding member 1 4. The arrangement of polyester shaped fibers ensures that shielding member 1 4 can have good light resistance while taking into account air permeability. Shielding member 2 5 is kneaded by bamboo charcoal fibers 1, the bamboo charcoal fibers 1 are put into an automatic pilling machine to knead to form shielding member 2 5. Bamboo charcoal fibers are often darker gray in color, so shielding member 2 5 can stably absorb external light under the action of bamboo charcoal fibers 1, further reducing the light transmittance of the fabric.

[0024] like Figure 1 and Figure 3 As shown, the shielding sheet 3 is woven by shielding yarn 7, which includes a shielding yarn core 8 and a shielding covering yarn 9 spirally wound on the outside thereof. The shielding yarn core 8 and the shielding covering yarn 9 are processed by spindle spinning to form the shielding yarn 7. The shielding yarn core 8 is formed by twisting bamboo charcoal fiber 2 through a twisting machine, and the shielding covering yarn 9 is formed by twisting polyester fiber 1 through a twisting machine. The polyester fiber 1 has good light resistance and structural strength. The light resistance and durability of the fabric are enhanced by the setting of the polyester fiber 1.

[0025] like Figure 1 and Figure 4 As shown, the base layer 1 is woven by composite yarn 10, and the composite yarn 10 includes a composite yarn core 11 and a composite covering yarn 12 spirally wound on the outside thereof. The composite yarn core 11 and the composite covering yarn 12 are processed by a spindle spinning process to form the composite yarn 10. The composite yarn core 11 is formed by twisting polyester fiber through a twisting machine, and the composite covering yarn 12 is formed by twisting acrylic fiber through a twisting machine. Acrylic fiber not only has good sunlight resistance, but also the structural strength of acrylic fiber will not decrease when exposed to sunlight for a long time, thereby enhancing the durability of the fabric.

[0026] like Figure 1-Figure 4As shown, when the fabric needs to be made, the composite yarn 10 is put into a shuttle loom and woven to form a base layer 1, and a laser cutting machine is used to cut along one side of the base layer 1 to form a plurality of breathable grooves 2, and the shielding yarn 7 is put into the shuttle loom and woven to form a shielding layer, and a glue coating machine is used to coat the shielding layer with glue, and a shielding piece 1 4 and a shielding piece 2 5 are bonded to the shielding layer, and the shielding layer is cut along the thickness direction by a laser cutting machine to form a plurality of shielding sheets 3, and finally the shielding sheets 3 are sewed to the base layer 1 by a sewing machine.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
