[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 cloth is formed by weaving polyester composite yarn in warp and weft. Due to the characteristics of polyester fiber, polyester cloth is often used to make clothing, home textiles, etc.

[0004] Curtain is a common home textile. In order to ensure good light-shielding performance during use, the weaving density of the curtain fabric will be increased, thereby reducing the channel through which the outside sunlight passes. In order to ensure the quality of a nap, people will close the door and draw the curtains. After a period of time, the indoor temperature is high and people feel stuffy. The increase in the weaving density of the fabric will reduce the pores inside the fabric for air to pass through, thereby affecting the circulation of indoor and outdoor air and aggravating the uncomfortable feeling of stuffiness. Therefore, a structure is provided to solve the problem that the fabric cannot take into account both light-shielding and breathability. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a sun-proof polyester fabric, which can improve the overall light-shielding performance of the fabric through structural settings.

[0007] The utility model is further configured as follows: a plurality of through holes are provided on the light shielding sheet, and a plurality of through holes are provided on the inner layer which are staggered with the through holes.

[0008] The utility model is further configured as follows: a light absorbing part is fixedly connected in the groove.

[0009] The utility model is further configured as follows: the support portion is located at two sides of the outer layer, and the support portion and the outer layer are integrally formed.

[0010] The utility model is further configured as follows: the outer layer is woven by shading yarn, the shading yarn is twisted by shading core yarn one and shading core yarn two, the shading core yarn one is twisted by polyester fiber, and the shading core yarn two is twisted by bamboo charcoal fiber.

[0011] The utility model is further configured as follows: the diameter of the first shading core yarn is greater than the diameter of the second shading core yarn.

[0012] The utility model is further configured as follows: the inner layer is woven by breathable yarn, the breathable yarn includes a breathable yarn core and a breathable covering yarn spirally wound on the outside thereof, the breathable yarn core is twisted by ramie fibers, and the breathable covering yarn is twisted by polyester fibers.

[0013] In summary, the utility model has the following beneficial effects: the setting of the shading part and the groove reduces the connecting area between the through hole and the through hole, prevents external sunlight from directly passing through the through hole and the through hole to irradiate the user's body surface, and ensures the shading property of the fabric when in use. The setting of the light absorbing part makes the inner wall of the groove uneven. When external sunlight shines into the groove through the through hole, it will be reflected in all directions under the setting of the light absorbing part. The shading performance of the fabric during use is further enhanced through the structural setting. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The sun-proof polyester fabric, such as Figure 1 and Figure 2As 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, the arrangement of the inner layer 1 and the outer layer 2 increases the path of external sunlight penetrating the fabric, and reduces the light of external sunlight penetrating the fabric into the room, the side of the outer layer 2 close to the inner layer 1 is formed with a plurality of shading sheets 3 by heat pressing, the side of the inner layer 1 close to the outer layer 2 is formed with a groove 4 by heat pressing, the side of the shading sheet 3 close to the inner layer 1 extends into the groove 4, and a transparent space is formed between the inner layer 1 and the outer layer 2 through a support portion 5. The air channel, under the support of the supporting part 5, increases the distance between the inner layer 1 and the outer layer 2 and forms a breathable channel. The setting of the breathable channel realizes the connection between the air inside and outside the fabric, so that the outside air can enter the fabric through the air inlet of the breathable channel, diffuse through the pores inside the fabric, and then enter the room through the air outlet of the breathable channel, thereby realizing the circulation of indoor and outdoor air. The setting of the shading sheet 3 reduces the connection area of ​​the air inlet and the air outlet of the breathable channel, thereby preventing the outside sunlight from directly shining into the room through the breathable channel.

[0021] like Figure 1 and Figure 2 As shown, the arrangement of the groove 4 enables the inner layer 1 to form a space for the shading sheet 3 to move. When in use, the fabric will be blown by the external airflow so that the outer layer 2 moves toward the inner layer 1. Under the blowing of the external airflow, the shading sheet 3 will move toward the inner bottom surface of the groove 4. Through the arrangement of the supporting part 5, there is always a channel for the external air to flow through between the shading sheet 3 and the groove 4. Through the arrangement of the structure, the fabric has a certain degree of air permeability while having shading performance.

[0022] like Figure 1 and Figure 2 As shown, a plurality of through holes 6 coinciding with the axis of the groove 4 are punched on the shading sheet 3 by a laser punching machine. The setting of the through holes 6 provides a channel for outside air to enter the fabric, and the side of the shading sheet 3 close to the inner layer 1 is located in the groove 4. The setting of the groove 4 can limit the range of movement of the shading sheet 3 to prevent the shading sheet 3 from swinging under the drive of the external airflow, thereby causing the through holes 6 to be closed. The inner layer 1 is provided with a plurality of through holes 7 staggered with the through holes 6 by a laser punching machine. On the one hand, the opening of the through holes 7 increases the porosity inside the fabric, so that the outside air can flow through the through holes 7 into the room, further ensuring the air permeability of the fabric when in use. On the other hand, the setting of the through holes 7 avoids direct connection with the through holes 6, so that the inner layer 1 has good air permeability while ensuring a certain light-shielding property.

[0023] like Figure 1-Figure 3As shown, a light absorbing part 8 which coincides with the axis of the through hole 6 is fixedly connected in the groove 4, and the light absorbing part 8 is arranged as a fluff layer, and the material of the fluff layer is arranged as bamboo charcoal fiber 11. The bamboo charcoal fiber 11 is first cut into short fibers by a cutting machine, and then the cut bamboo charcoal fiber 11 is put into a flocking machine, and the fluff layer is fixed in the groove 4 by electrostatic flocking of the flocking machine. The arrangement of the light absorbing part 8 increases the roughness of the bottom surface of the groove 4. When external sunlight passes through the through hole 6 and shines into the groove 4, it will be stably absorbed by the fluff in the light absorbing part 8, thereby ensuring the light-shielding property of the inner layer 1 when in use. The color of the bamboo charcoal fiber 11 is darker, so it can absorb part of the external sunlight. Under the action of the bamboo charcoal fiber 11, the light absorbing part 8 can further ensure the light-shielding and sun-proof performance of the fabric when in use.

[0024] like Figure 2 and Figure 3 As shown, the outer layer 2 is woven by shading yarn 9, and the shading yarn 9 is twisted by shading core yarn 1 and shading core yarn 2, and the shading core yarn 1 and the shading core yarn 2 are twisted by a twisting machine to form the shading yarn 9, and the shading core yarn 1 is twisted by polyester fiber 10 through a twisting machine. The polyester fiber 10 has good light resistance. The characteristics of the polyester fiber 10 are used to further enhance the shading and light resistance of the outer layer 2 and the overall fabric when in use. The shading core yarn 2 is twisted by bamboo charcoal fiber 11 through a twisting machine. The bamboo charcoal fiber 11 has a certain anti-ultraviolet function, and the color of the bamboo charcoal fiber 11 is mostly gray or dark gray, so it can better absorb external light, and the overall performance of the fabric is further increased by the provision of the bamboo charcoal fiber 11.

[0025] like Figure 2-Figure 4 As shown, the diameter of the shading core yarn one is larger than the diameter of the shading core yarn two, the support portion 5 is located on both sides of the outer layer 2, and the support portion 5 is integrally formed with the outer layer 2. The difference in diameter between the shading core yarn one and the shading core yarn two makes the shading yarn 9 naturally form a bulge during weaving, so that the shading yarn 9 will naturally form support portions 5 on both sides of the outer layer 2 when the outer layer 2 is woven.

[0026] like Figure 1 and Figure 4As shown, the inner layer 1 is woven by breathable yarn 12, and the breathable yarn 12 includes a breathable yarn core and a breathable covering yarn spirally wound on the outside thereof. The breathable yarn core and the breathable covering yarn are processed by a spindle spinning process to form the breathable yarn 12, and the breathable yarn core is twisted by a ramie fiber 13 through a twisting machine. The ramie fiber 13 has the characteristics of good moisture absorption and fast moisture dissipation. The characteristics of the ramie fiber 13 are used to further ensure the breathability of the inner layer 1 during use. The interior of the ramie fiber 13 is a prismatic structure, so that it can reflect external sunlight well. The characteristics of the ramie fiber 13 are used to prevent external sunlight from directly passing through the fabric into the room. The breathable covering yarn is twisted by a polyester fiber 10 through a twisting machine. The polyester fiber 10 has good structural strength and wear resistance. The overall performance of the inner layer 1 is enhanced by the arrangement of the polyester fiber 10.

[0027] like Figure 1-Figure 4 As shown, when it is necessary to make the fabric, the breathable yarn core and the breathable covering yarn are processed by a mule spinning process to form a breathable yarn 12, the breathable yarn 12 is put into an air jet loom for weaving to form an inner layer 1, the inner layer 1 is hot-pressed by a hot press to form a plurality of grooves 4, through holes 7 are opened along the thickness direction of the inner layer 1 by a laser punching machine, the light absorbing part 8 is fixed on the inner wall of the groove 4 by flocking by a flocking machine, the shading core yarn 1 and the shading core yarn 2 are twisted by a twisting machine to form a shading yarn 9, and the shading yarn 9 is fixed by a flocking machine. The optical yarn 9 is put into the air-jet loom to weave the outer layer 2 and the support part 5. The outer layer 2 is formed into the shading sheet 3 by the heat pressing method of the heat press, and the through hole 6 is formed along the thickness direction of the shading sheet 3 by the laser cutting machine. The operator spreads the inner layer 1 flat on the table, and places the inner layer 1 with the side where the groove 4 is formed facing upwards. The operator then places the outer layer 2 on the inner layer 1, and under the action of gravity, the shading sheet 3 is located in the groove 4. Finally, the inner layer 1 and the outer layer 2 are sewed together by a sewing machine.
