Description

Technical Field

[0001] This utility model relates to the field of fabrics, and more specifically, to a sun-protective and heat-insulating fabric. Background Technology

[0002] Traditional sun protection and heat insulation fabrics often involve adding a coating to a flat woven fabric. However, the heat insulation effect of flat fabrics is limited, and the coating will peel off due to long-term exposure to the sun, thus affecting the overall sun protection and heat insulation performance of the fabric. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sun-protective and heat-insulating fabric. The fabric is made by interweaving two warp yarns with a single weft yarn to form a double-sided structure. The double-sided structure increases the thickness of the fabric, thereby increasing the blocking of ultraviolet rays and heat insulation. The surface of the fabric reflects and scatters ultraviolet rays through a structure of protrusions of different sizes, thereby reducing the penetration of direct light. The inside of the fabric forms a flat structure, and the interweaving between the surface and the inside of the fabric forms a hollow space, thereby preventing external heat from entering.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a sun-protective and heat-insulating fabric, characterized in that it includes a surface and an inner surface from the outside to the inside, the surface includes a first region, a second region and a third region, the first region and the second region are both higher than the third region, the first region and the inner surface form a first hollow region, and the second region and the inner surface form a second hollow region.

[0005] The present invention is further configured such that the protrusion height of the first region and the second region are the same, and the height difference H between the first region and the third region is 1mm-2.2mm.

[0006] The present invention is further configured such that, located on the surface, the first region is arranged in groups of five, with each group of the first regions arranged diagonally, and the five first regions in each group are arranged in an alternating manner.

[0007] The present invention is further configured such that, located in the surface, the second region is arranged in groups of three, with each group of the second region arranged diagonally, and the three second regions in each group arranged in a triangular pattern.

[0008] The present invention is further configured such that the first region is rectangular, the long side of the first region is 8mm-11mm, and the short side of the first region is 1.8mm-2.5mm.

[0009] The present invention is further configured such that the second region is rectangular, the long side of the second region is 2.3mm-3mm, and the short side of the second region is 1.3mm-2mm.

[0010] The present invention is further configured such that the fabric consists of 94 warp yarns and 40 weft yarns in one cycle, with the odd number of warp yarns from the first to the 94th warp yarns interlacing with the weft yarns to form the surface, and the even number of warp yarns from the first to the 94th warp yarns interlacing with the weft yarns to form the inside.

[0011] In summary, this utility model has the following beneficial effects:

[0012] The fabric is double-sided by interlacing two types of warp yarns with a single type of weft yarn, which increases the thickness of the fabric and effectively blocks some ultraviolet rays and heat. The different sizes and intervals of the bumps on the surface of the fabric increase the reflection and scattering of ultraviolet rays, thereby reducing penetration. The flat structure inside the fabric creates a hollow space between the surface and the inside of the fabric, which maintains the stability of the fabric and prevents external heat from entering.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 — Figure 4As shown, this embodiment discloses a sun-protective and heat-insulating fabric. The fabric has 94 warp yarns and 40 weft yarns in one cycle. The odd-numbered warp and weft yarns of the first 1-94 warp yarns interweave to form the surface 100, and the even-numbered warp and weft yarns of the first 1-94 warp yarns interweave to form the inner 200. Therefore, the fabric includes the surface 100 and the inner 200 from the outside to the inside. In the surface 100 formed by the interweaving of odd-numbered warp and weft yarns, 28 warp yarns and 4 weft yarns interweave to form the first region 101, 4 warp yarns and 2 weft yarns interweave to form the second region 102, and 20 warp yarns and 20 weft yarns interweave to form the third region 103. Because the 28 warp yarns and 4 weft yarns in the first region 101 interweave with plain weave and floats, and the plain weave is located between the two floats, and the third region 103 is located around the first region 101, and the third region... Region 103 is a broken twill weave, so the first region 101 is higher than the third region 103. Similarly, since the four warp yarns and two weft yarns of the second region 102 are interwoven into a plain weave, and the third region 103 is a broken twill weave, and the second region 102 is located within the third region 103, the second region 102 is also higher than the third region 103. The first region 101 and the second region 102 have the same height of protrusion, and the height difference H between the first region 101 and the third region 103 is 1mm-2.2mm. Preferably, the height difference H between the first region 101 and the third region 103 is 2mm. Therefore, the height difference between the second region 102 and the third region 103 is also 2mm. This makes the surface 100 form an uneven fabric, thereby reflecting and scattering ultraviolet rays through the uneven structure, thus reducing the penetration of direct light.

[0020] Because the first region 101 has the length of 28 warp yarns and the width of 4 weft yarns, it is rectangular. The long side of the first region 101, formed by the interlacing of warp and weft yarns, is 8mm-11mm, preferably 9.8mm. The short side of the first region 101 is 1.8mm-2.5mm, preferably 2.2mm. The second region 102 has the length of 4 warp yarns and the width of 2 weft yarns, therefore it is also rectangular. The length of the second region 102 is 2.3mm-3mm, preferably 2.8mm, and the length of the short side is 1.3mm-2mm, preferably 1.8mm. This forms rectangular protrusions of different sizes on the surface 100. The rectangular protrusions of different sizes not only cause ultraviolet rays to be reflected and scattered multiple times on the fabric surface 100, thereby reducing the transmittance of ultraviolet rays, but also allow the fabric surface 100 to block and reflect ultraviolet rays from multiple directions when it comes into contact with them, thereby increasing the sun protection of the fabric.

[0021] Within surface 100, the first region 101 is arranged in groups of five, with each group of five regions 101 arranged diagonally and in an alternating pattern. This arrangement creates a serrated pattern along the short sides of the first region 101 when they are grouped in groups of five. This allows the fabric surface 100 to reflect ultraviolet rays while increasing the airflow of the fabric through the floats. Within surface 100, the second region 102 is arranged in groups of three, with each group of three regions 102 arranged diagonally and in a triangular pattern. The different arrangements of the second region 102 and the first region 101 increase the complexity of the fabric surface 100, thereby slowing down the heat transfer rate.

[0022] The inner layer 200 is formed by interlacing even-numbered warp and weft yarns, and it uses a 1-up, 3-down twill weave. Therefore, the interlaced inner layer 200 forms a twill, increasing the heat conduction path compared to a flat structure, thus enhancing the fabric's insulation. Because the first region 101 is raised, it forms the first hollow region 300 with the inner layer 200. The second region 102 is also raised, forming the second hollow region 400 with the inner layer. Since the first regions 101 are grouped in sets of five and arranged alternately, and because the plain weave of the first regions 101 is located between two floats, the plain weave area of ​​the first regions 101 is raised. Therefore, the first hollow region 300 is also alternately arranged with the alternate arrangement of the first regions 101. Similarly, the second hollow region 400 is also triangularly arranged with the triangular arrangement of the second regions 102. Therefore, the presence of hollow areas increases the thickness of the fabric beyond its original single-layer structure, thereby blocking ultraviolet rays and isolating heat. The air inside the first hollow area 300 and the second hollow area 400 prevents external heat from entering, thus giving the fabric its heat-insulating properties. Because the first hollow area 300 is located below the first region 101 and the second hollow area 400 is located below the second region 102, and because the first region 101 and the second region 102 are not continuously connected, the first hollow area 300 and the second hollow area 400 are arranged alternately. This prevents the fabric from becoming loose due to complete hollowness, thus providing UV protection on the surface 100 and heat insulation on the inside 200. Furthermore, the alternating arrangement of the first hollow area 300 and the second hollow area 400 prevents heat from accumulating inside the fabric, allowing heat to dissipate and ensuring the fabric's heat-insulating performance.

[0023] The surface 100 uses sun-protective fibers, and its uneven structure further enhances its sun protection. The hollow area formed by the surface 100 and the inner 200 prevents some heat from entering, while the inner 200 uses heat-insulating fibers, further increasing the fabric's heat insulation. The surface 100 and the inner 200 are formed by the interweaving of double warp and weft yarns, thus creating a double-sided structure. This double-sided structure makes the fibers more tightly arranged, allowing the surface 100 to provide better sun protection, while the inner 200 can better prevent heat from entering. This prevents ultraviolet rays and heat from entering through the gaps between the fibers, thus affecting the fabric's sun protection and heat insulation properties. The double-sided structure, combined with fiber weaving, replaces the traditional coating process, making the fabric more durable.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. 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.
