Description

Technical Field

[0001] The utility model relates to the technical field of fabrics, and more specifically, to a polyester fabric. Background Art

[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. Taking advantage of the characteristics of polyester fibers, polyester fabric is often used to make clothing and other daily necessities.

[0004] In order to reduce the light transmittance of polyester fabrics used in clothing, the weave density of the fabric is often increased during fabric production to reduce the pores inside the fabric for light to pass through. However, when people are outdoors, the high weave density of the fabric affects the circulation and exchange of air on both sides of the fabric, making people feel stuffy when using the fabric. Therefore, a structure is provided to solve the problem that some fabrics cannot achieve both light blocking and breathability when used. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a polyester fabric that improves the overall sun protection and breathability of the fabric through structural settings.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a polyester fabric comprises an inner layer and an outer layer fixedly connected to each other, a plurality of ventilation grooves are provided on the outer layer, a connecting piece with the same width as the ventilation groove is fixedly connected to the side wall of the ventilation groove, a plurality of support blocks are fixedly connected to the inner layer and abut against the movable end of the connecting piece, the thickness of the support block is greater than the depth of the ventilation groove, and there is ventilation space between adjacent support blocks, and the light transmittance of the inner layer and the support block is less than the light transmittance of the outer layer and the connecting piece.

[0007] The present invention is further configured as follows: the thickness of the inner layer is greater than the thickness of the outer layer, and the inner layer and the support block are both woven by light-shielding yarn.

[0008] The utility model is further configured as follows: a plurality of through holes are opened on the inner layer, and the through holes and the ventilation grooves are staggered.

[0009] The utility model is further configured as follows: the inner layer and the support block are integrally formed, the inner layer is configured as a warp pattern structure, the ground structure of the warp pattern structure is the inner layer, and the flower structure of the warp pattern structure is the support block.

[0010] The utility model is further configured as follows: the shading yarn includes a shading core yarn 1 and a shading core yarn 2, the shading core yarn 1 is formed by twisting bamboo charcoal fibers, and the shading core yarn 2 is formed by twisting polyester shaped fibers.

[0011] The utility model is further configured as follows: the outer layer is woven by sun-proof yarns, and the sun-proof yarns include a first sun-proof core yarn and a second sun-proof core yarn.

[0012] The utility model is further configured as follows: the first sun-proof core yarn is formed by twisting polyester fibers, and the second sun-proof core yarn is formed by twisting acrylic fibers.

[0013] To sum up, the utility model has the following beneficial effects: since the thickness of the support block is greater than the depth of the ventilation groove, the connecting piece that is against the support block is in an inclined state, and the outside air can flow between the movable end of the connecting piece and the inner wall of the ventilation groove and pass through the through hole to contact the user's body surface. The color depth of the support block and the inner layer is greater than that of the connecting piece and the outer layer, so the inner layer can better absorb external light, and the sun protection and ventilation effect of the fabric when used is guaranteed by reducing the amount of light passing through the inner layer and the user's body surface.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] The 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 double-layer fabric allows the light entering the fabric to be better reflected and absorbed by the fabric. A number of ventilation grooves 3 are provided on the outer layer 2. A connecting piece 4 with the same width as the ventilation groove 3 is integrally formed on the side wall of the ventilation groove 3. A U-shaped groove is formed by cutting along the thickness direction of the outer layer 2 using a laser cutting machine, and the cut side of the outer layer 2 hangs down on the outer layer 2 to form a connecting piece 4.

[0021] like Figure 1 and Figure 2 As shown, the inner layer 1 is fixedly connected with a number of support blocks 5 that abut against the movable ends of the connecting pieces 4. The thickness of the support blocks 5 is greater than the depth of the ventilation grooves 3. Therefore, the connecting pieces 4 abutting against the support blocks 5 are in an inclined state. Since the width of the connecting pieces 4 is equal to that of the ventilation grooves 3, there is a channel between the connecting pieces 4 and the upper surface of the outer layer 2 for the outside air to enter. The connecting pieces 4 abutting against the support blocks 5 can close part of the ventilation grooves 3, thereby reducing the amount of light that passes through the ventilation grooves 3 and directly shines on the inner layer 1, ensuring the sun protection and breathability of the fabric when used.

[0022] like Figure 1 and Figure 2 As shown, there is a breathable space between adjacent support blocks 5, so that the support blocks 5 reduce the channels for external light to pass through between the connecting piece 4 and the outer layer 2 while increasing the channels for external air to flow into the fabric, so that the fabric can ensure the breathable effect while ensuring the light-shielding effect. The light transmittance of the inner layer 1 and the support blocks 5 is less than that of the outer layer 2 and the connecting piece 4, which further reduces the amount of light that passes through the inner layer 1 and shines on the user's body surface.

[0023] like Figure 1-Figure 3 As shown, the thickness of the inner layer 1 is greater than that of the outer layer 2, which further prolongs the time for the light in contact with the inner layer 1 to pass through the inner layer 1, so that the light is gradually reflected inside the fabric to reduce the amount of light in contact with the user's body surface. The inner layer 1 and the support block 5 are both woven with shading yarn 7, and the characteristics of the shading yarn 7 are used to enhance the shading effect of the inner layer 1 and the support block 5.

[0024] like Figure 1 and Figure 2 As shown, a number of through holes 6 are opened along the thickness direction of the inner layer 1 by a laser punching machine, and the through holes 6 are staggered with the ventilation grooves 3. The setting of the through holes 6 reduces the contact area between the inner layer 1 and the user's body surface and increases the amount of air in contact with the user's body surface. The staggered setting of the ventilation grooves 3 and the through holes 6 can reduce the amount of light entering the fabric along the ventilation grooves 3 and directly passing through the through holes 6 and the user's body surface, thereby enhancing the sun protection and breathability performance of the structure when in use.

[0025] like Figure 1 and Figure 2As shown, the inner layer 1 and the support block 5 are integrally formed, and the inner layer 1 is set as a warp pattern structure, the ground structure of the warp pattern structure is the inner layer 1, and the flower structure of the warp pattern structure is the support block 5. Through the setting of the warp pattern structure, the inner layer 1 can naturally form a number of support blocks 5 on its surface during weaving, thereby ensuring the stability of the structure during production and use.

[0026] like Figure 3 As shown, the shading yarn 7 includes a shading core yarn 1 8 and a shading core yarn 2 9. The shading core yarn 1 8 and the shading core yarn 2 9 are twisted by a twisting machine to form the shading yarn 7. The shading core yarn 1 8 is twisted by a twisting machine from bamboo charcoal fiber. The bamboo charcoal fiber is a darker gray in color. Therefore, the shading yarn 7 can stably absorb the light that comes into contact with it under the action of the bamboo charcoal fiber. The shading core yarn 2 9 is twisted by a twisting machine from polyester shaped fiber with a Y cross-sectional shape. The setting of the polyester shaped fiber increases the channel for external air to flow through the inside of the shading yarn 7, further optimizing the breathable and comfortable performance of the structure during use.

[0027] 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 a twisting machine from polyester fiber, and the good light resistance of polyester fiber is used to enhance the light resistance and sun protection performance of the fabric. The sun-proof core yarn 2 12 is twisted by an acrylic fiber through a twisting machine. Acrylic fiber has good sunlight resistance, and the structural strength of acrylic fiber will not decrease when exposed to light for a long time. The light resistance and durability of the fabric are enhanced by the setting of acrylic fiber.

[0028] like Figure 1-Figure 4 As shown, when the fabric needs to be made, the sun-proof yarn 10 is placed in a shuttle loom and woven to form an outer layer 2, and a laser cutting machine is used to cut along the thickness direction of the outer layer 2 to form a number of U-shaped breathable grooves 3 and connecting pieces 4, and the shading yarn 7 is placed in a shuttle loom and woven through a warp weaving method to form an inner layer 1 and a number of support blocks 5, and a laser punching machine is used to open a number of through holes 6 along the thickness direction of the inner layer 1, and finally the inner layer 1 and the outer layer 2 are sewn together by a sewing machine.

[0029] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. 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.
