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

[0019] The light-blocking breathable polyester fabric, such as Figure 1 and Figure 2As shown, it includes an inner layer 1 and an outer layer 2 which are sewn and fixed together. A laser cutting machine is used to cut a plurality of through grooves 3 on the side of the outer layer 2 away from the inner layer 1. The through grooves 3 provide a channel for the fabric to exchange air with the outside, so that the fabric has better air permeability. A light-blocking sheet 4 for blocking the through grooves 3 is sewn and fixed on the surface of the outer layer 2. The light-blocking sheet 4 can reduce the amount of sunlight penetrating into the fabric from the through grooves 3. A support strip 5 extending from the through grooves 3 is bonded to the side of the inner layer 1 close to the outer layer 2. The support strip 5 is against the surface of the light-blocking sheet 4. An air permeable cavity 7 is formed between the light blocking sheet 4 and the support bar 5. Two air permeable grooves 6 connected to the outside are provided on the side of the surface of the light blocking sheet 4 away from the support bar 5, so that the fabric is connected with the air permeable cavity 7 through the air permeable grooves 6. The distance between the support bar 5 and the inner wall of the through-groove 3 is smaller than the distance between the support bar 5 and the inner wall of the air permeable groove 6. The air permeable grooves 6 are connected with the air permeable cavity 7 to achieve the ventilation effect of the fabric while reducing the sunlight entering the fabric from the through-groove 3, thereby ensuring that the fabric has good air permeability and good light-shielding effect.

[0020] like Figure 1 and Figure 2 As shown, adjacent air grooves 6 are arranged on both sides of the support strip 5 along the width direction of the light blocking sheet 4, so that the fabric itself is more evenly breathable. A laser punching machine is used to form a number of air holes 8 on the surface of the inner layer 1. The air holes 8 can enhance the air permeability and heat dissipation performance of the inner layer 1 fabric. The width of the through groove 3 is greater than the width of the support strip 5, so that a space for air to pass through is formed between the support strip 5 and the inner wall of the through groove 3, thereby achieving the purpose of increasing the air circulation channel and improving the breathability of the fabric. The height of the support strip 5 is greater than the height of the through groove 3, so that after the support strip 5 passes through the through groove 3, the support strip 5 applies a thrust to the light blocking sheet 4 away from the side of the inner layer 1 of the fabric, so that an air cavity 7 is formed between the light blocking sheet 4 and the support strip 5, so that the breathability of the fabric itself is better.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the inner layer 1 and the support strip 5 are both woven from support yarn 9 by a shuttle loom, the support yarn 9 includes a core yarn 10 and an outer covering wire 11 wound around the outside of the core yarn 10, the core yarn 10 and the outer covering wire 11 are formed by a spindle spinning process, the core yarn 10 is made of polyester shaped fiber twisted by a twisting machine, the cross-sectional shape of the polyester shaped fiber is set to a triangle, because the triangle itself has good support and stability performance, the strength of the support yarn 9 itself is greater, the support effect of the support strip 5 on the light blocking sheet 4 is more stable, the outer covering wire 11 is made of flax fiber twisted by a twisting machine, flax fiber has good air permeability and UV resistance, thereby enhancing the sun protection and air permeability of the inner layer 1.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the outer layer 2 is woven by a shading yarn 12 through a shuttle loom. The shading yarn 12 includes a core yarn 13 and an outer wire 14 wound around the outside of the core yarn 13. The core yarn 13 and the outer wire 14 are formed by a spindle spinning process. The core yarn 10 is made of polyester fiber and twisted by a twisting machine. The polyester fiber has the characteristics of high strength, good heat resistance and not easy to fade, which makes the shading yarn 12 itself more durable and less likely to fade under long-term sunlight exposure. 14 is made of nylon fiber 1 twisted by a twisting machine. Nylon fiber 1 has the characteristics of good light-shielding property and high wear resistance, making the outer layer 2 more light-shielding and durable. The light-blocking sheet 4 is woven by a blocking yarn through a shuttle loom. The blocking yarn is made of multiple strands of nylon fiber 2 twisted by a twisting machine. Nylon fiber has the characteristics of good elasticity and high wear resistance. After the support bar 5 is abutted against the light-blocking sheet 4, the light-blocking sheet 4 undergoes elastic deformation, and the air permeable groove 6 also increases its deformation, thereby enhancing the air permeability effect of the fabric itself.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the fabric needs to be made, the inner layer 1 and the support cloth are formed by putting the support yarn 9 into a shuttle loom and weaving, and the support cloth is then cut by a cutting machine to form a plurality of support sheets, and the multiple support sheets are overlapped and bonded to form a support strip 5 with a height greater than the outer layer 2, and the support strip 5 is bonded to one side of the inner layer 1, and a laser puncher is used to punch holes along the thickness direction of the inner layer 1 to form air holes 8, and the outer layer 2 is formed by putting the shading yarn 12 into the shuttle loom and weaving, and the through groove 3 is formed by cutting along the thickness direction of the outer layer 2 using a laser cutting machine, and the shading yarn is put into the shuttle loom. The inner layer 2 is woven to form a light-blocking cloth, and then a shearing machine is used to cut the light-blocking cloth into a predetermined size to form a number of light-blocking sheets 4, which are laid flat together, and a laser cutting machine is used to cut along the thickness direction of the light-blocking sheets 4 to form air permeable grooves 6. Finally, the outer layer 2 is laid flat on the table, and the light-blocking sheets 4 are covered on top of the air permeable grooves 6. A sewing machine is used to sew the light-blocking sheets 4 to the outer layer 2, and then the inner layer 1 is aligned with the outer layer 2 so that the support strip 5 is inserted into the through groove 3, and then a sewing machine is used to sew the inner layer 1 and the outer layer 2 together, and finally the process of making a whole piece of fabric is completed.

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.
