Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabrics, and more specifically, to a light-blocking fabric. Background Technology
[0002] Existing blackout fabrics often use coatings to block sunlight, but these coatings can peel off during use, thus affecting the fabric's blackout performance. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a light-blocking fabric. This fabric uses different satin weaves to create variations in float length. The warp float length of the third unit is longer than that of the first unit, the warp float length of the first unit is longer than that of the second unit, and the warp float length of the second unit is longer than that of the middle and side areas. Therefore, each unit creates different shadow areas through different float lengths, resulting in different reflections in different areas. Because the warp float length of the third unit is the longest and lower than other areas, the fabric reflects and scatters light at different angles. Furthermore, the different float lengths result in different coverage areas between the warp and weft yarns, thereby reducing light transmission.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a light-blocking fabric, comprising a first region and a second region arranged alternately and cyclically along the fabric width direction. The first region comprises a first unit and a second unit arranged in a 1:1 ratio along the fabric width direction. The second region comprises a third unit and a fourth unit arranged alternately and cyclically along the fabric length direction. The fourth unit comprises a middle region and side regions located on both sides. The first unit, the second unit, the third unit, the middle region, and the side regions are all made of satin weave. The warp float of the third unit is the longest, and the weft float of the middle region is the longest.
[0005] The present invention is further configured such that, in the first region, the warp float line of the first unit is longer than that of the second unit, and in the second region, the warp float line of the third unit is longer than that of the fourth unit.
[0006] The present invention is further configured such that the warp float line of the third unit is longer than the warp float line of the first unit, and the warp float line of the second unit is longer than the warp float line of the fourth unit.
[0007] The present invention is further configured such that the third unit is lower than the first region and the fourth unit.
[0008] The present invention is further configured such that the length of the third unit is twice that of the fourth unit, and the width of the third unit is the same as the width of the fourth unit and the width of the first region.
[0009] The present invention is further configured such that the fourth unit is arranged obliquely at an angle of 45-60 degrees.
[0010] The present invention is further configured such that the fabric has a weave cycle of 168 warp yarns and 48 weft yarns, with 14 warp yarns and 48 weft yarns interwoven to form the first region, and 14 warp yarns and 48 weft yarns interwoven to form the second region.
[0011] The present invention is further configured such that, in the first region, 7 warp yarns and 48 weft yarns interweave to form the first unit, and 7 warp yarns and 48 weft yarns interweave to form the second unit.
[0012] The present invention is further configured such that, in the second region, 14 warp yarns and 32 weft yarns interweave to form the third unit, and 14 warp yarns and 16 weft yarns interweave to form the fourth unit.
[0013] The present invention is further configured such that, in the fourth unit, 8 warp yarns and 16 weft yarns interweave to form the middle region, the side region located on one side of the middle region is formed by 4 warp yarns and 16 weft yarns interweaving, and the side region located on the other side of the middle region is also formed by 4 warp yarns and 16 weft yarns interweaving.
[0014] In summary, this utility model has the following beneficial effects:
[0015] Different satin weaves create variations in float length, resulting in different shaded areas. The warp float length of the third unit is longer than that of the first unit, which is longer than that of the second unit. The warp float length of the second unit is longer than that of the middle and side areas. This difference in float length creates different reflections in the fabric. The warp float length of the third unit is the longest and lower than that of other areas, allowing the fabric to reflect and scatter light at different angles. Furthermore, the varying float lengths create different coverage areas between the warp and weft yarns, thus reducing light transmission. Attached Figure Description

[0021] 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.
[0022] like Figure 1 — Figure 4As shown, this embodiment discloses a light-blocking fabric. The fabric has a weave of 168 warp yarns and 48 weft yarns per cycle, and is made of glass fiber and polyester fiber. In one weave cycle, 14 warp yarns and 48 weft yarns interweave to form a first region 100, and 14 warp yarns and 48 weft yarns interweave to form a second region 200. Because the warp direction of the fabric has a cycle of 168 warp yarns, the first region 100 formed by the interweaving of 14 warp yarns and weft yarns and the second region 200 formed by the interweaving of 14 warp yarns and weft yarns are alternately arranged for 6 cycles. The first region 100 is located in the... Warp yarns 15-28, 43-56, 71-84, 99-112, 127-140, and 155-168 are included. The second region 200 consists of warp yarns 1-14, 29-42, 57-70, 85-98, 113-126, and 141-154. Therefore, along the fabric width, it includes alternating and cyclically arranged first region 100 and second region 200. Within the warp and weft interlacing range of the first region 100, seven warp yarns in each first region 100 form a six-up, two-down group. The first unit 101 is formed by weaving together 7 warp yarns in a 5-up-3-down weave, while the second unit 102 is formed by weaving together 7 warp yarns in a 5:3 weave. Therefore, within the first region 100, the first unit 101 is formed by weaving together 7 warp yarns and 48 weft yarns, and the second unit 102 is formed by weaving together 7 warp yarns as a group. Within the first region 100, the two groups of warp yarns are interwoven in a 1:1 ratio. Therefore, the first region 100 includes the first unit 101 and the second unit 102 arranged 1:1 along the fabric width direction. Because the first unit 101 is a 6-up-2-down weave, the warp float of the first unit 101 is 6. The first unit 101 has 5 warp points and 2 weft floats, while the second unit 102 has a 5-up, 3-down weft structure. Therefore, the second unit 102 has 5 warp floats and 3 weft floats. Thus, it is located in the first region 100. The warp float of the first unit 101 is longer than that of the second unit 102, thus creating a gradient warp float between the first unit 101 and the second unit 102. This results in different float structure between the first unit 101 and the second unit 102, and thus different shadow areas. Therefore, the fabric can form different reflections through the coverage of different floats.
[0023] Within the warp and weft interlacing area of the second region 200, in each second region 200, warp yarns 1-14 and weft yarns 1-32 interlaced in a 7-up-1-down weave to form a third unit 201. Warp yarns 1-4 and 11-14 interlaced with weft yarns 33-48 in a 3-up-5-down weave, and warp yarns 5-10 interlaced with weft yarns 33-48 in a 2-up-6-down weave. Therefore, warp yarns 1-14 interlaced with weft yarns 33-48 to form a fourth unit 202. Thus, the second region 200 includes the third unit 201 and the fourth unit 202, which are arranged alternately and cyclically along the fabric length. Within the second region 200, 14 warp yarns and 32 weft yarns interlaced to form... The third unit 201 is formed by the interweaving of 14 warp yarns and 16 weft yarns to form the fourth unit 202. Within the interweaving range of the warp and weft yarns in the fourth unit 202, warp yarns 1-4 and 11-14 interweave with weft yarns 33-48 to form the side region 2022 of the fourth unit 202, and warp yarns 5-10 interweave with weft yarns 33-48 to form the middle region 2021 of the fourth unit 202. Therefore, the fourth unit 202 includes the middle region 2021 and the side regions 2022 located on both sides. Within the fourth unit 202, 8 warp yarns and 16 weft yarns interweave to form the middle region 2021. The side area 2022 on the side is formed by 4 warp yarns and 16 weft yarns interlaced. The side area 2022 on the other side of the middle area 2021 is also formed by 4 warp yarns and 16 weft yarns interlaced. Because the third unit 201 is a 7-up-1-down weave, the warp float of the third unit 201 has 7 warp weave points and the weft float has 1 weft weave point. In the fourth unit 202, the side area 2022 is a 3-up-5-down weave, therefore the warp float of the fourth unit 202 has 3 warp weave points and the weft float has 5 weft weave points. The middle area 2021 in the fourth unit 202 is a 2-up-6-down weave, therefore the middle area of the fourth unit 202... In region 2021, the warp float has 2 warp weft points and the weft float has 6 weft weft points. Therefore, it is located in the second region 200. The warp float of the third unit 201 is longer than the warp float of the fourth unit 202, while the weft float of the fourth unit 202 is longer than the weft float of the third unit 201. This causes the third unit 201 and the fourth unit 202 to form floats with different structures in the warp and weft directions. Because the floats of the third unit 201 and the fourth unit 202 are different, the gaps caused by the interlacing of warp and weft yarns can be blocked by the floats in different directions, thereby creating a uniform light-blocking effect in the fabric and reducing the gaps between the yarns, thus reducing the light transmittance of the fabric.
[0024] Because Unit 3 201 is a 7-up-1-down weave with a 7-way weave length, Unit 1 101 is a 6-up-2-down weave with a 6-way weave length, Unit 2 202 is a 5-up-3-down weave with a 5-way weave length, the side area 2022 in Unit 4 202 is a 3-up-5-down weave with a 3-way weave length, and the middle area 2021 in Unit 4 202 is a 2-up-6-down weave with a 2-way weave length, the buoyancy length of Unit 3 201 is longer than that of Unit 1 101, and the buoyancy length of Unit 2 102 is longer than that of Unit 4 202. The fabric has a satin weave, with the first unit 101, the second unit 102, the third unit 201, the middle area 2021, and the side area 2022 all using a satin weave. The warp float of the third unit 201 is the longest, and the weft float of the middle area 2021 is the longest. Therefore, the warp float and weft float on the fabric surface form a gradient or an interlacing pattern, resulting in irregular textures and shadow areas. When light shines on the fabric surface, it is first reflected or refracted by the warp float or weft float, and then further reflected or refracted by the weft float or warp float. This increases the path and number of reflections and refractions of light on the fabric surface, thereby reducing the chance of light transmission.
[0025] Because the warp float of the third unit 201 is the longest, when the warp and weft yarns interweave, the warp float of the third unit 201 has fewer interweaving times. As a result, due to the internal stress of the yarns between the units after interweaving, the third unit 201 is lower than the first region 100 and the fourth unit 202. Therefore, the third unit 201 forms an uneven surface with the first unit 101, the second unit 102, and the fourth unit 202. Through the uneven surface structure of the fabric, when the fabric is exposed to light, the uneven structure can reflect and scatter light at multiple angles, thereby reducing the transmission of light. In addition, the uneven structure causes the fibers of the fabric to bend at the uneven points, thereby allowing air to circulate freely inside and outside the fabric, thus increasing the breathability of the fabric.
[0026] Because the third unit 201 has a length of 32 weft yarns and the fourth unit 202 has a length of 16 weft yarns, the length of the third unit 201 is twice that of the fourth unit 202 along the fabric length direction. Since both the third unit 201 and the fourth unit 202 have a width of 14 warp yarns, the width of the third unit 201 is the same as the width of the fourth unit 202. The width of the first region 101 is also the width of 14 warp yarns. Therefore, the width of the third unit 201 is the same as the width of the fourth unit 202 and the width of the first region 100. This allows the warp floats and weft floats to be distributed more evenly, thus avoiding the uneven shading phenomenon that may be caused by floats in one direction.
[0027] Because in one cycle of 168 warp yarns, at the intersection of warp and weft yarns where Unit 202 is located, Unit 202 is in warp yarns 1-14, at the intersection of warp yarns 1-14 and weft yarns 33-48, in warp yarns 29-42, at the intersection of warp yarns 29-42 and weft yarns 1-16, in warp yarns 57-70, at the intersection of warp yarns 57-70 and weft yarns 17-32, in warp yarns 85-98, at the intersection of warp yarns 85-98 and weft yarns 33-38, Unit 202 is... In warp yarns 113-126, the fourth unit 202 is located at the intersection of warp yarns 113-126 and weft yarns 1-16. In warp yarns 141-154, the fourth unit 202 is located at the intersection of warp yarns 141-154 and weft yarns 17-32. Therefore, three adjacent fourth units 202 are arranged at an angle of 45-60 degrees on the 48 weft yarns. Thus, the fourth units 202 are arranged obliquely at an angle of 45-60 degrees. Preferably, the fourth units 202 are arranged obliquely at an angle of 45 degrees. Therefore, the fourth units 202 can form a gap in the warp floats of the third unit 201, thereby reducing the phenomenon of snagging or breaking due to excessive warp floats, which would affect the light-blocking effect.

All technical solutions falling within the scope of this utility model's concept are protected.
