A type of blackout fabric

Abstract

This utility model discloses a light-blocking fabric, comprising a base fabric area and a curved area. Multiple rows of curved areas are interspersed within the base fabric area. The base fabric area includes a first region and a second region arranged alternately along the fabric's length, with the first region higher than the second region. The curved areas include a third region and a fourth region arranged diagonally alternately, with the third region higher than the fourth region. The first and third regions are at the same height, as are the second and fourth regions. In this utility model, the fiber interlacing path in the base fabric area is straight, while the fiber interlacing path in the curved areas is curved. The fibers at the junction of the base fabric area and the curved areas are inclined due to the interlacing path of the curved areas, causing the fibers in the curved areas to interlace in a curved manner. Some fibers in the base fabric area interlace at an inclined manner, thus partially covering the gaps between fibers, thereby reducing the penetration of direct light and lowering the light transmittance.

Description

Technical Field

[0001] This utility model relates to the field of fabrics, and more specifically, to a light-blocking fabric. Background Technology

[0002] Traditional fabrics use a multi-layered structure to achieve light blocking, which increases the cost of the fabric. On the other hand, the single-layered structure of traditional fabrics uses a plain weave, which creates gaps between the fibers, allowing light to pass through the straight gaps and reducing the fabric's light-blocking ability. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a light-blocking fabric. The fiber interlacing path in the base fabric area is straight, while the fiber interlacing path in the curved area is curved. The fibers at the junction of the base fabric area and the curved area are inclined due to the interlacing path of the curved area, causing the fibers in the curved area to interlac in a curved shape. The fibers at and near the junction of the base fabric area and the curved area interlac in an inclined shape. Furthermore, the float lengths on the two sides of the base fabric area and the curved area are different, resulting in different effects on both sides of the fabric. The gaps between the fibers formed by the float lengths and the curved interlacing reduce the penetration of direct light and lower the light transmittance. The base fabric area forms a longitudinal concave-convex structure along the fabric's length, while the curved area forms a transverse concave-convex structure along the fabric's width, creating concave-convex structures on the fabric surface in different directions. Compared to flat fabrics, light is reflected and scattered multiple times in multiple directions due to the concave-convex structure, thus reducing direct light penetration. The single-layer structure of the fabric increases its thickness, thereby improving the light-blocking effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a light-blocking fabric, comprising a base fabric area and a curved area, wherein multiple rows of the curved areas are interspersed in the base fabric area, the base fabric area comprising a first area and a second area arranged alternately along the length of the fabric, the first area being higher than the second area, the curved area comprising a third area and a fourth area arranged obliquely and alternately, the third area being higher than the fourth area, the first area and the third area being at the same height, and the second area and the fourth area being at the same height.

[0005] The present invention is further configured such that, along the length of the fabric, one of the two adjacent rows of the curved areas is rotated 180 degrees to obtain the other row of the curved areas.

[0006] The present invention is further configured such that the curved area includes five third regions and four fourth regions, the two short sides of each third region are connected to the two short sides of the first region, and each fourth region is connected to the second region.

[0007] The present invention is further configured such that, within the curved region, the third region and the fourth region are alternately arranged along a 45-degree direction.

[0008] The present invention is further configured such that the height difference between the first region and the second region is equal to the height difference between the third region and the fourth region, and the height difference is 0.3mm-1.2mm.

[0009] The present invention is further configured such that the width L1 of the first region is equal to the width L2 of the second region, and the width L3 of the third region is equal to the width L4 of the fourth region.

[0010] The present invention is further configured such that one weave cycle of the base fabric area is formed by the interweaving of 6 warp yarns and 24 weft yarns, and one weave cycle of the curve area is also formed by the interweaving of 6 warp yarns and 24 weft yarns.

[0011] The present invention is further configured such that the warp yarn of the fabric is made of 75D polyester and the weft yarn is made of 40-count viscose.

[0012] The present invention is further configured such that the warp density of the fabric is 180 threads / inch and the weft density is 120 threads / inch.

[0013] In summary, this utility model has the following beneficial effects:

[0014] The fiber interlacing path in the curved area involves the fibers interlacing in a curved shape. At the same time, the fibers at the junction of the base fabric area and the curved area, as well as near the junction, interlaced at an angle. Furthermore, the base fabric area and the curved area form double-sided floating threads through interlacing, which allows the curved fibers and floating threads to cover the gaps between the interlaced fibers, thereby reducing the penetration of direct light. The base fabric area forms a longitudinal concave-convex structure along the length of the fabric, while the curved area forms a transverse concave-convex structure along the width of the fabric. This creates concave-convex structures on the fabric surface in different directions, causing the fabric to be reflected and scattered multiple times in multiple directions, thereby reducing light transmittance. In addition, the concave-convex structure increases the thickness and density of the fabric, thus improving the light-blocking effect. Attached Figure Description

[0022] 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.

[0023] like Figure 1 — Figure 6As shown, this embodiment discloses a light-blocking fabric. The fabric is woven on a large jacquard loom with a warp density of 180 threads / inch and a weft density of 120 threads / inch. The warp yarns are made of 75D polyester, and the weft yarns are made of 40-count viscose. The woven fabric includes a base fabric area 1 and a curved area 2. Multiple rows of curved areas 2 are interwoven in the base fabric area 1 in a jacquard pattern. Along the length of the fabric, one row of curved areas 2 is rotated 180 degrees to obtain another row of curved areas 2, so that adjacent rows of curved areas 2 can restrict each other in the base fabric area 1, thereby increasing the structural stability of the fabric. When weaving the base fabric area 1, one weave cycle of the base fabric area 1 is 6. The base fabric area 1 is formed by interlacing 6 warp yarns with 24 weft yarns. Warp yarns 1-6 interlac with weft yarns 1, 2, 5, 6, 9, 10, 13, 14, 17, 18, 21, and 22 to form the outer side of the base fabric area 1. Warp yarns 1-6 interlac with weft yarns 3, 4, 7, 8, 11, 12, 15, 16, 19, 20, 23, and 24 to form the inner side of the base fabric area 1. Therefore, the ratio of weft yarns on the inner and outer sides of the base fabric area 1 is 2:2. Furthermore, the warp weave points on the outer side of the base fabric area 1 are larger than those on the inner side, and the weft weave points on the outer side are smaller than those on the inner side. When weaving curve area 2, one weave cycle of curve area 2 consists of 6 warp yarns and 2... Four weft yarns interweave to form the outer side of curve zone 2. Warp yarns 1-6 interweave with weft yarns 1, 2, 5, 6, 9, 10, 13, 14, 17, 18, 21, and 22 to form the outer side of curve zone 2. Warp yarns 1-6 interweave with weft yarns 3, 4, 7, 8, 11, 12, 15, 16, 19, 20, 23, and 24 to form the inner side of curve zone 2. Therefore, the ratio of weft yarns on the inner and outer sides of curve zone 2 is 2:2. Furthermore, the warp weave point on the outer side of curve zone 2 is smaller than that on the inner side, while the weft weave point on the outer side is larger than that on the inner side. Thus, by creating different interweaving effects on both sides of the base fabric zone 1 and curve zone 2, the overall fabric quality is enhanced. The thickness replaces both traditional multi-layer and single-layer fabrics. Therefore, the outer surface of base fabric area 1 is mainly covered by warp yarns, and the inner surface of base fabric area 1 is mainly covered by weft yarns. This allows the inner float yarns of base fabric area 1 to cover part of the outer interlacing gaps, and the outer float yarns of base fabric area 1 to cover part of the inner interlacing gaps. Similarly, the outer surface of curved area 2 is mainly covered by weft yarns, and the inner surface of curved area 2 is mainly covered by warp yarns. This allows the inner float yarns of curved area 2 to cover part of the outer interlacing gaps, and the outer float yarns of curved area 2 to cover part of the inner interlacing gaps, thereby reducing the light transmittance of the fabric.

[0024] Within the interlacing range of the 6 warp yarns and 24 weft yarns in curve zone 2, warp yarns 1-6 interlace with weft yarns 1, 2, 5, 6, 9, 10, 13, 14, 17, 18, 21, and 22 to form the outer side of curve zone 2. Warp yarns 1-6 interlace with weft yarns 1, 2, 9, 10, 17, and 18 to form the third region 21, and warp yarns 1-6 interlace with weft yarns 5, 6, 13, 14, 21, and 22 to form the second region 22. Because curve zone 2 is formed through jacquard interlacing, it includes the third region 21 and the fourth region 22 arranged diagonally alternately, and the width L3 of the third region 21 is equal to the width of the first region 21. The width L4 of the fourth region 22 is located in the curved region 2. The third region 21 and the fourth region 22 are arranged alternately along a 45-degree direction. In the interlacing range of the 6 warp yarns and 24 weft yarns in the base fabric region 1, the 1st to 6th warp yarns interlac with the 1st, 2nd, 5th, 6th, 9th, 10th, 13th, 14th, 17th, 18th, 21st, and 22nd weft yarns to form the outer side of the curved region 2. The 1st to 6th warp yarns interlac with the 1st, 2nd, 9th, 10th, 17th, and 18th weft yarns to form the first region 11, and the 1st to 6th warp yarns interlac with the 5th, 6th, 13th, 14th, 21st, and 22nd weft yarns to form the second region 12. Therefore, the base fabric region 1 includes alternating regions along the length of the fabric. The arrangement includes a first region 11 and a second region 12, where the width L1 of the first region 11 is equal to the width L2 of the second region 12. The curved region 2 includes five third regions 21. Each third region 21 of the curved region 2 is formed by interlacing warp and weft yarns at the same position with the first region 11 of the base fabric region 1. Therefore, the two short sides of each third region 21 connect to the two short sides of the first region 11. The curved region 2 also includes four fourth regions 22. Each fourth region 22 of the curved region 2 is formed by interlacing warp and weft yarns at the same position with the second region 12 of the base fabric region 2. Therefore, each fourth region... 22 is connected to the second region 12, so the yarn interlacing path of the base fabric region 1 is straight, while the curved region 2 is jacquard. The outline is defined by the large jacquard machine, so the yarn interlacing path of the curved region 2 is curved. The yarn at the junction of the base fabric region 1 and the curved region 2 will be partially tilted due to the yarn interlacing path of the curved region 2. Therefore, the yarn of the curved region 2 is interlaced in a curved shape, while some of the yarn of the base fabric region 1 is interlaced in an inclined shape. Thus, the angle of the gap between the yarns is increased by the curved yarn, and the gap between the yarns is partially covered by the fabric float of the curved region 2, thereby reducing the penetration of direct light and reducing the light transmittance.

[0025] Because the first region 11 is located where the 1st to 6th warp yarns intersect with the 1st, 2nd, 9th, 10th, 17th, and 18th weft yarns, each weft yarn in the first region 11 interweaves to form 5 warp weaving points. The second region 12 is located where the 1st to 6th warp yarns intersect with the 5th, 6th, 13th, 14th, 21st, and 22nd weft yarns, each weft yarn in the second region 12 interweaves to form 4 warp weaving points. Therefore, the warp float length of the first region 11 is greater than that of the second region 12, making the first region 11 higher than the second region 12. Region 21 is located where warp yarns 1-6 intersect with weft yarns 1, 2, 9, 10, 17, and 18. Each weft yarn in Region 21 intersects to form 5 weft weaving points. Region 22 is located where warp yarns 1-6 intersect with weft yarns 5, 6, 13, 14, 21, and 22. Each weft yarn in Region 22 intersects to form 4 warp weaving points. Therefore, the weft float length of Region 21 is greater than that of Region 22, making Region 21 higher than Region 22. This is because Region 21... Both the first region 11 and the third region 21 have 5 weft points on their floating threads, so the first region 11 and the third region 21 are at the same height. The second region 12 and the fourth region 22 both have 4 warp points or 4 weft points, so the second region 12 and the fourth region 22 are at the same height. The height difference between the first region 11 and the second region 12 is equal to the height difference between the third region 21 and the fourth region 22, and the height difference is 0.3mm-1.2mm, preferably 0.5mm. Therefore, the base fabric region 1 forms a longitudinal concave-convex structure in the fabric length direction, and the curved region 2 interweaves to form a transverse concave-convex structure in the fabric width direction, so that the fabric surface forms concave-convex structures in different directions. Compared with flat fabric, light will be reflected and scattered multiple times in multiple directions due to the concave-convex structure, thereby reducing the direct penetration of light. At the same time, the structural base fabric region 1 and the curved region 2 form different structures on both sides through the weaving structure, so that the floating threads on both sides can cover each other's interweaving gaps and increase the thickness of the fabric, thereby improving the light blocking effect without increasing the weight of the fabric.
