[0020] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.
[0021] As shown in Figure 1 Figure 4 The embodiment discloses a breathable shading fabric, which comprises a first longitudinal strip area 100 and a second longitudinal strip area 200. The first longitudinal strip area 100 is formed by interweaving the first 1-24 warp yarns and the first 1-32 weft yarns, wherein the first 1-16 warp yarns in the first 1-24 warp yarns are interwoven for three cycles, and the first 1-32 weft yarns are interwoven for 15 cycles. The second longitudinal strip area 200 is formed by interweaving the second 25-72 warp yarns and the first 1-32 weft yarns, wherein the first 1-32 weft yarns are interwoven for 15 cycles. Therefore, the fabric is formed by interweaving 104 warp yarns and 480 weft yarns for one cycle. In one weave cycle, in the first 1-24 warp yarns and the first 1-32 weft yarns interwoven in the first longitudinal strip area 100, the ninth 16 warp yarns and the first 1-8 weft yarns are interwoven to form the first groove 102, and the ninth 16 warp yarns and the seventeenth 24 weft yarns are interwoven to form the first groove 102. In addition to the warp and weft yarns interwoven in the first groove 102, the remaining warp and weft yarns are interwoven to form the first base cloth area 101. Therefore, the first longitudinal strip area 100 comprises the first base cloth area 101 and the first groove 102. Since the first 1-16 warp yarns in the first 1-24 warp yarns are interwoven for three cycles, and the first 1-32 weft yarns are interwoven for 15 cycles, each first longitudinal strip area 100 comprises three first grooves 102, and the three first grooves 102 are distributed in the first base cloth area 101, so that the first grooves 102 can be uniformly distributed in the first longitudinal strip area 100.
[0022] The second longitudinal strip area 200 is formed by the interlacing of the 25th-72nd warp yarns with the 1st-32nd weft yarns, and in one weave cycle, the 25th-40th warp yarns interlace with the 1st-32nd weft yarns to form the second base area 201, the 41st-56th warp yarns interlace with the 9th-24th weft yarns to form the second groove area 202, the 41st-56th warp yarns interlace with the 1st-8th weft yarns and the 25th-32nd weft yarns to form the second base area 201, the 57th-72nd warp yarns interlace with the 1st-32nd weft yarns to form the second base area 201, the second longitudinal strip area 200 comprises the second base area 201 and the second groove area 202, and each second longitudinal strip area 200 comprises one second groove area 202, and the second groove area 202 is located in the middle of the second base area 201.
[0023] Taking a first groove 102 as an example, the first groove 102 is formed by the interlacing of the 9th-16th warp yarns with the 1st-8th weft yarns, the weft float length formed by the interlacing of the 1st-4th weft yarns gradually decreases, the weft float length formed by the interlacing of the 6th-8th weft yarns gradually increases, the warp float length formed by the interlacing of the 9th-11th warp yarns gradually decreases, the warp float length formed by the interlacing of the 15th-16th warp yarns gradually increases, and the first base area 101 is a plain weave, because the density of the first groove 102 is lower than that of the first base area 101 under the same density, the first groove 102 is lower than the first base area 101, and the second groove area 202 is formed by the interlacing of the 41st-56th warp yarns with the 9th-24th weft yarns, the weft float length formed by the interlacing of the 9th-16th weft yarns gradually decreases, the weft float length formed by the interlacing of the 18th-24th weft yarns gradually increases, the warp float length formed by the interlacing of the 41st-47th warp yarns gradually decreases, the warp float length formed by the interlacing of the 51st-56th warp yarns gradually increases, and similarly, the density of the second groove area 202 is lower than that of the second base area 201 under the same density, so the second groove area 202 is lower than the second base area 201, and thus the first groove 102 and the second groove area 202 form different float lengths, so that the fabric has a certain level inside through the difference of the float length on the surface of the fabric, thereby increasing the air flow path of the air in the fabric, thereby increasing the air permeability of the fabric, and because the float length on the surface of the fabric is different, the coverage of the float length is reduced, and because the float length is longer than the exposed length of the interlaced warp and weft yarns, more light can be reflected and scattered, thereby increasing the light-shielding property of the fabric.
[0024] Because the first groove 102 is formed by interweaving 8 warp yarns and 8 weft yarns, and the second groove 202 is formed by interweaving 16 warp yarns and 16 weft yarns, the second groove 202 is larger than the first groove 102, and because the first groove 102 is formed by gradually reducing or gradually increasing the length of the warp and weft floats among the 8 warp yarns and 8 weft yarns, and the second groove 202 is formed by gradually reducing or gradually increasing the length of the warp and weft floats among the 16 warp yarns and 16 weft yarns, because of the difference in the length of the floats, the depth of the first groove 102 and the second groove 202 also differs, therefore, in the first longitudinal strip area 100, the depth H of the first groove 102 is 0.5mm-3mm, preferably, the depth H of the first groove 102 is 1mm, and in the second longitudinal strip area 200, the depth L of the second groove 202 is 1mm-6mm, preferably, the depth L of the second groove 202 is 2mm, therefore, the first groove 102 and the second groove 202 form different cavity heights by having different depths, and therefore, by having different lengths of floats, the surface of the fabric forms different undulations based on the first base fabric area 101 and the second base fabric area 201, thereby promoting air exchange inside and outside the fabric, further increasing the air permeability of the fabric.
[0025] Because the first groove 102 has 8 warp yarns and 8 weft yarns, and the second groove 202 has 16 warp yarns and 16 weft yarns, the first groove 102 is a square, the width C of the first groove 102 is 0.2cm-1.2cm, preferably, the width C of the first groove 102 is 0.8cm, the second groove 202 is also a square, but the width E of the second groove 202 is 0.4cm-2.4cm, preferably, the width E of the second groove 202 is 1.6cm, therefore, the second groove 202 is larger than the first groove 102, and therefore, the first groove 102 and the second groove 202 are different by having different widths and heights, therefore, the second groove 202 has more angles of reflection and scattering of light than the first groove 102, and the second groove 202 also has more reflection and scattering paths when light contacts, thereby forming different levels of light-shielding effects on the fabric, thereby increasing the light-shielding property of the fabric, if only the first groove 102 exists, because the size of the first groove 102 is too small, the air permeation path on the surface of the fabric is limited, thereby causing the problem of insufficient air permeability of the fabric, and if only the second groove 202 exists, because the size of the second groove 202 is too large, the light-shielding effect on the surface of the fabric is not uniform, and only the second groove 202 makes the air flow at the second groove 202 smooth, but other places are not air permeable, thereby making the air permeation effect of the fabric as a whole not uniform.
[0026] Because the first base cloth area 101 is located between two first grooves 102 along the length direction of the fabric, and also has 8 weft yarns, and the second base cloth area 201 is also located between two second grooves 202, but has 16 weft yarns, therefore the width F of the second base cloth area 201 is twice of the width D of the first base cloth area 101, because the first base cloth area 101 and the second base cloth area 201 are plain weave and adopt high density weaving method, therefore the first base cloth area 101 and the second base cloth area 201 form good light shielding property, but because the first base cloth area 101 has the first grooves 102 and the second base cloth area 201 has the second grooves 202, therefore the average density of the first vertical strip area 100 is higher than that of the second vertical strip area 200, therefore when the fabric is woven, because of the density difference between the two vertical strip areas, when the fabric naturally falls in place, a bend is formed at the joint of the two vertical strip areas, therefore when the fabric naturally forms a bend, when the fabric contacts light, the light increases the propagation path, thereby reducing the direct light, and because the fabric forms a natural bend, and the surface of the fabric forms a differentiated concave-convex structure, therefore the air can not only flow between the two grooves formed cavities, but also because the bend can increase the air flow between the two vertical strip areas, thereby further increasing the air permeability of the fabric.
[0027] The preferred embodiments of the present application have been described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical scheme falling within the idea of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application, these improvements and decorations should also be considered as the protection scope of the present application.
