Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, and more specifically, to sun-resistant and durable polyester fabric. Background Technology

[0002] Polyester fiber is a chemical fiber with high strength, good light resistance, and good heat resistance. Polyester is widely used in the production of various types of clothing.

[0003] Polyester greige fabric refers to fabric made of polyester fibers. It is usually used as a raw material for various clothing, furniture, curtains, etc. In order to make polyester greige fabric have a sun protection effect, the following methods are used to improve its sun protection performance: increasing the weave density, adding a sun protection coating, and increasing the fabric thickness. However, all of the above methods will reduce the breathability of the greige fabric. When this greige fabric is used in clothing or curtains, it is difficult for air to exchange between the two sides of the fabric, which will reduce the comfort of the fabric.

[0004] Therefore, it is necessary to design a polyester fabric that has good sun protection while also being breathable, thus improving its applicability and making it suitable for various scenarios. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sun-proof and durable polyester fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The sun-proof and durable polyester fabric includes a surface layer and an inner layer. The surface layer has a plurality of light-shielding parts on its end face away from the inner layer. Each light-shielding part includes a plurality of light-shielding strips. The surface layer has a plurality of through holes (I) that are located between adjacent light-shielding strips. The diameter of each through hole is less than or equal to the height of the light-shielding strip. The inner layer has a plurality of support parts on its end face near the surface layer. Each support part includes a plurality of support strips. The inner layer has a plurality of through holes (II) that are located between adjacent support strips. The top surface of each support strip abuts against the bottom surface of the surface layer. The light-shielding parts and the support parts are staggered.

[0007] The present invention is further configured such that: a plurality of the light-shielding parts are arranged in a matrix array on the surface layer, and a plurality of the supporting parts are arranged in a matrix array on the inner layer, wherein the shape and size of the horizontal projection surface of the light-shielding parts are the same as the shape and size of the horizontal projection surface of the supporting parts.

[0008] The present invention is further configured such that the height of the light-shielding strip is between 0.5mm and 1.5mm, and the spacing between adjacent light-shielding strips is between 1mm and 1.5mm.

[0009] The present invention is further configured such that the light-shielding strip is a silicone strip.

[0010] The present invention is further configured such that: the shape and size of the horizontal projection surface of the light-shielding part are the same as the shape and size of the horizontal projection surface of the support part, and the support strip supports the cavity formed between the inner layer and the outer layer.

[0011] The present invention is further configured such that the height of the support strip is less than or equal to the height of the light-shielding strip.

[0012] In summary, this utility model has the following beneficial effects: During the use of the fabric, when light shines on the surface, the light-blocking strip can block or reflect some of the light, reducing the possibility of direct light shining through the first perforation. The setting of the aperture of the first perforation and the height of the light-blocking strip further restricts the path of light shining into the first perforation. Air can enter between the surface and inner layers through the first perforation and flow to the other side of the fabric through several second perforations on the inner layer, achieving both light blocking and sun protection while also having a certain breathability. The setting of the support part on the inner layer creates a cavity between the inner and outer layers. During the use of the fabric, it is compressed and deformed, causing the internal cavity to deform as well, forming an air pressure difference between the inside and outside of the fabric, further increasing the exchange speed of air between the inside and outside of the fabric, and improving the overall comfort of the fabric.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Sun-protective and durable polyester fabric, such as Figure 1 , Figure 2 and Figure 3As shown, the fabric includes an outer layer 1 and an inner layer 5. The outer layer 1, on its side away from the inner layer 5, has several light-blocking portions, each including several light-blocking strips 2. Several perforations 4 are drilled through the outer layer. The light-blocking strips 2 are arranged in a linear array, with the perforations 4 located between adjacent light-blocking strips 2. The diameter of the perforations 4 is less than or equal to the height of the light-blocking strip 2. The inner layer 5, on its side near the outer layer 1, has several support portions, each including several support strips 6. The support strips 6 are arranged in the same way as the light-blocking strips 2. Several perforations 7 penetrate the inner layer 5 and are located between adjacent support strips 6. The top surface of the support strips 6 abuts against the bottom surface of the outer layer 1. The light-blocking portions and support portions are alternately arranged. Through the light-blocking strips 2 on the outer layer 1 and the perforations 4 located between adjacent light-blocking strips 2, light shines onto the outer layer 1 during use. The light-blocking strip 2 can block or reflect some light, reducing the possibility of light passing through the perforation 4. The setting of the aperture of the perforation 4 and the height of the light-blocking strip 2 ensures that oblique light is blocked by the light-blocking strip 2. Only light that shines vertically on the fabric can pass through the perforation 4 to the maximum extent, limiting the angle at which light enters the perforation 4. Air can enter between the outer layer 1 and the inner layer 5 through the perforation 4 and flow to the other side of the fabric through several perforations 7 on the inner layer 5, achieving both light blocking and sun protection while also having a certain degree of breathability. The setting of the support part on the inner layer 5 creates a cavity between the inner layer 5 and the outer layer 1. During use, the fabric is compressed and deformed, causing the internal cavity to deform as well, creating an air pressure difference between the inside and outside of the fabric. This further increases the speed of air exchange between the inside and outside of the fabric, improving the overall comfort of the fabric.

[0020] like Figures 1-4 As shown, the fabric structure of the outer layer 1 and the inner layer 5 is set as plain weave. Plain weave has the characteristics of being tight, structurally stable, and having good strength, which can achieve a good light-blocking effect. The yarn used to weave the base layer and the inner layer 5 is set as polyester yarn. Polyester yarn has the characteristics of good light resistance, high strength, and good abrasion resistance, which can ensure that the fabric has good strength, abrasion resistance, and service life. In order to improve the overall light-blocking effect of the fabric, a higher count polyester yarn can be selected. The high count polyester yarn combined with the plain weave with good weave density can make the fabric have a good light-blocking effect. The polyester fibers are fed into the loom and the outer layer 1 and the inner layer 5 are woven according to the plain weave structure sequence.

[0021] like Figures 1-4 As shown, after obtaining the outer layer 1 and the inner layer 5, a number of ventilation holes are laser-drilled on the end faces of the outer layer 1 and the inner layer 5 using a laser drilling machine. Several perforations 4 are formed on the outer layer 1 and several perforations 7 are formed on the inner layer 5 by laser drilling. The number of perforations 4 and the number of perforations 7 are linearly arrayed on the end faces of the outer layer 1 and the inner layer 5, respectively, in order to improve the ventilation effect of the outer layer 1 or the inner layer 5.

[0022] like Figures 1-4 As shown, the light-shielding strip 2 is made of silicone. After obtaining the surface layer 1 with several perforations 4 and the inner layer 5 with several perforations 7, a silicone printing machine is used to print on the end faces of the surface layer 1 and the inner layer 5. The printing position is near the perforations 4 on the surface layer 1 and near the perforations 7 on the inner layer 5. The printing shape is a long rectangle, with printing on the top and bottom sides of a row of perforations 7 or perforations 4. After the silicone material cools, several light-shielding strips 2 are formed on the surface layer 1 and several support strips 6 are formed on the inner layer 5. The silicone printing machine can stably form several light-shielding strips 2 and several support strips 6 on the surface layer 1 and the inner layer 5 respectively. Several light-shielding parts are arranged in a matrix array on the surface layer 1 and several support parts are arranged in a matrix array on the inner layer 5. The shape of the horizontal projection surface of the light-shielding parts is... The shape and size of the light-blocking strip 2 are consistent with the shape and size of the horizontal projection surface of the support part, which ensures the stability of the structure of the outer layer 1 and the inner layer 5 and has an aesthetic effect. Preferably, the height of the light-blocking strip 2 is between 0.5mm and 1.5mm, the spacing between adjacent light-blocking strips 2 is between 1mm and 1.5mm, and the aperture of the perforation 4 is less than or equal to the height of the light-blocking strip 2. The height of the light-blocking strip 2 can reduce the propagation path of light entering the perforation 4. That is, the higher the light-blocking strip 2, the smaller the angle at which light can enter the perforation 4, and the less light enters. The spacing between adjacent light-blocking strips 2 mainly depends on the distance between two adjacent rows of perforations 4. A light-blocking groove 3 is formed between adjacent light-blocking strips 2. By narrowing the width of the light-blocking groove 3, the possibility of light entering the perforation 4 is further reduced, thereby improving the overall light-blocking effect of the fabric.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the height of the support strip 6 is less than or equal to the height of the blackout strip 2. The height of the support strip 6 is set to ensure that the cavity volume between the outer layer 1 and the inner layer 5 is not too large. If the cavity inside the fabric is too large, heat dissipation will become slow, the wearing comfort will easily decrease, and the thickness will increase significantly. On the other hand, a smaller cavity can make it more difficult for light to spread, thus having a better blackout effect.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, when the outer layer 1 and inner layer 5 are composited, the inner layer 5 has several support strips 6 with their ends facing upwards, and the outer layer 1 has several light-blocking strips 2 with their ends facing upwards. The top of the support strips 6 abuts against the bottom of the outer layer 1. Since light shines in a straight line, the staggered light-blocking and support parts can reduce the possibility of light directly passing through the fabric. This structure makes the overall structure of the fabric more uniform and more stable. Finally, the outer layer 1 and inner layer 5 are sewn together by a sewing machine, or glue is applied to the contact surfaces of the outer layer 1 and inner layer 5 before the two layers are bonded together, thus completing the processing and manufacturing of this sun-protective and durable polyester fabric.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
