[0003] In order to reduce the amount of light that passes through the fabric and reaches the user's body surface, people often increase the thickness of the fabric to reduce the light transmittance of the fabric. When the thickness increases, the fabric will affect the air circulation on both sides of the fabric, making people feel stuffy. Therefore, a structure is provided to solve the problem that thick fabrics cannot achieve both sun protection and breathability. Utility Model Content

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0018] The sun-protective polyester fabric, such as Figure 1 and Figure 2 As shown, it includes an inner layer 1 and an outer layer 2 fixedly connected to each other. The inner layer 1 and the outer layer 2 are sewn together by a sewing machine. A plurality of through holes 3 are formed on the outer layer 2 by weaving a mesh tissue. The setting of the through holes 3 provides a channel for the outside air to stably enter the interior of the fabric, ensuring the breathability of the structure when in use. A blocking piece 4 is fixedly connected to the inner layer 1 and extends into the through hole 3. The width of the blocking piece 4 is smaller than the width of the through hole 3. The setting of the blocking piece 4 can reduce the amount of light entering the interior of the fabric through the through hole 3.
[0019] like Figure 1 and Figure 2As shown, a light-absorbing sheet 5 is fixedly connected to the inner layer 1 in the same relative position as the through hole 3, one side of the blocking sheet 4 is against the inner wall of the through hole 3, and the other side of the blocking sheet 4 is against the side wall of the light-absorbing sheet 5. The position of the blocking sheet 4 is set to reduce the amount of light passing through the outer peripheral wall of the blocking sheet 4 and the inner wall of the through hole 3. The length of the light-absorbing sheet 5 is greater than the length of the through hole 3, so that the light-absorbing sheet 5 can absorb the amount of light irradiated on the inner layer 1 by the through hole 3. The thickness of the light-absorbing sheet 5 is less than the thickness of the blocking sheet 4, so that the outside air can stably pass through the top surface of the light-absorbing sheet 5 and the channel of the outer layer 2 close to the side of the inner layer 1. The sun protection and breathability effect of the fabric when used is guaranteed by the structural setting.
[0020] like Figure 1 and Figure 2 As shown, the light-absorbing sheet 5 is integrally formed with the inner layer 1, and the light-absorbing sheet 5 is configured as a plurality of light-absorbing fleeces, which include a plurality of bamboo charcoal fibers. The inner layer 1 is placed in a napping machine and napped to form the light-absorbing fleece. The light-absorbing sheet 5 is configured as light-absorbing fleece so that the outside air can flow in the light-absorbing sheet 5. The bamboo charcoal fiber is often darker gray in color, so the light-absorbing fleece can stably absorb the light entering the inside of the fabric under the action of the bamboo charcoal fiber, thereby further enhancing the overall sun protection and light absorption performance of the structure.
[0021] like Figure 1 and Figure 2 As shown, a number of ventilation holes 6 are opened along the thickness direction of the inner layer 1 by a laser punching machine. The setting of the ventilation holes 6 reduces the amount of light that contacts the inner layer 1 with the user's body surface, so that the air flowing from the outside can directly pass through the inner layer 1 and contact the user's body surface, thereby enhancing the breathability and comfort of the fabric. The ventilation holes 6 are located on the side where the blocking piece 4 and the inner wall of the through hole 3 are against each other. By setting the position of the ventilation holes 6, the light that enters the fabric from the through hole 3 is extended to directly pass through the ventilation holes 6 and illuminate the user's body surface. Through the structural setting, the fabric can take into account the light-shielding and breathable effects at the same time.
[0022] like Figure 1-Figure 3 As shown, the barrier sheet 4 is integrally formed with the inner layer 1. The pattern of the inner layer 1 is five-way and one-cycle. The composite core yarn 2 9 passes through the second and third routes and forms a plurality of single-row tuck wales on the inner layer 1. The barrier sheet 4 is formed on the single-row tuck wales, and the difference between two adjacent single-row tuck wales is 3 stitches.
[0023] like Figure 1 and Figure 3As shown, the inner layer 1 is woven by composite yarn 7, which includes composite core yarn 1 8 and composite core yarn 2 9. Composite core yarn 1 8 and composite core yarn 2 9 are twisted by a twisting machine to form composite yarn 7. Composite core yarn 1 8 is twisted by polyester fiber 1 by a twisting machine. Polyester fiber 1 has good light resistance. The light resistance of the fabric is ensured by the setting of polyester fiber 1. Composite core yarn 2 9 is twisted by bamboo charcoal fiber by a twisting machine.
[0024] like Figure 1 and Figure 4 As shown, the outer layer 2 is woven by sun-proof yarn 10, and the sun-proof yarn 10 includes a sun-proof core yarn 11 and a sun-proof core yarn 2 12. The sun-proof core yarn 11 and the sun-proof core yarn 2 12 are twisted by a twisting machine to form the sun-proof yarn 10. The sun-proof core yarn 11 is twisted by acrylic fiber through a twisting machine. Acrylic fiber has good light resistance, and the structural strength of acrylic fiber will not decrease even if it is exposed to the air for a long time. The sun-proof core yarn 2 12 is twisted by polyester fiber 2 through a twisting machine. Polyester fiber 2 not only has good light resistance, but also has good structural strength and shape retention. The characteristics of acrylic fiber and polyester fiber 2 are used to enhance the light resistance and durability of the fabric.
[0025] like Figure 1-Figure 4 As shown, when the fabric needs to be made, the sun-proof yarn 10 is placed in a knitting machine and formed into an outer layer 2 and a plurality of through holes 3 through a mesh weaving method, the composite yarn 7 is placed in a knitting machine and woven into an inner layer 1 and a plurality of barrier sheets 4 through a half-rib weaving method, the inner layer 1 is placed in a napping machine and napped to form a plurality of light-absorbing sheets 5, and finally the inner layer 1 and the outer layer 2 are sewn together by a sewing machine.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
