An acetate fabric

Abstract

This utility model discloses an acetate fabric, including a base fabric area and triangular units. The base fabric area is between adjacent triangular units. Along the fabric width direction, two adjacent triangular units are arranged in an alternating cyclic pattern, with their hypotenuses facing each other. Two alternating triangular units form a group. Along the fabric length direction, two adjacent groups of triangular units are arranged in a horizontally symmetrical cyclic pattern. Each triangular unit includes multiple protrusions, arranged in a ratio of 1:2:3:4 or 4:3:2:1 along the fabric length direction. In this utility model, two adjacent triangular units are arranged horizontally symmetrically along both the fabric length and width directions, with their hypotenuses facing each other in the width direction. The triangular units are formed by protrusions, thus reducing the contact area on the fabric surface and hindering the free and continuous flow of charge on the flat fabric. This causes the charge to accumulate at the protrusions, resulting in a discrete charge distribution. Therefore, when the charge encounters a weak discharge opportunity, it is easier for the charge to dissipate locally.

Description

Technical Field

[0001] This utility model relates to the field of fabrics, and more specifically, to an acetate fabric. Background Technology

[0002] Acetate fabrics are widely used because of the good drape and luster of acetate fiber. However, acetate fiber has a low moisture regain rate, which makes the fabric poor in moisture absorption and thus prone to static electricity accumulation. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an acetate fabric. The base fabric area and triangular units are formed by the interlacing of warp and weft yarns. Two adjacent triangular units along the width of the fabric are also arranged horizontally symmetrically with their hypotenuses facing each other. Two adjacent triangular units along the length of the fabric are also arranged horizontally symmetrically, and each triangular unit is an equilateral triangle formed by protrusions. This reduces the contact area on the fabric surface and hinders the free and continuous flow of charge on the flat fabric, making it easier for the charge to accumulate at the protrusions. This results in a discrete distribution of the charge, making it easier for the charge to dissipate locally when it comes into contact with a weak discharge opportunity. At the same time, the airflow is enhanced by the concave areas on the front and back, thereby consuming some of the static charge.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an acetate fabric, comprising a base fabric area and triangular units, wherein the base fabric area is between adjacent triangular units, and adjacent two triangular units are arranged in an alternating cyclic pattern along the fabric width direction, with the hypotenuses of adjacent two triangular units facing each other, and two alternating triangular units forming a group, and adjacent two groups of triangular units are arranged in a horizontally symmetrical cyclic pattern along the fabric length direction, wherein the triangular unit includes multiple protrusions, and the protrusions are arranged in a ratio of 1:2:3:4 or 4:3:2:1 along the fabric length direction.

[0005] The present invention is further configured such that the triangular unit is an equilateral triangle.

[0006] The present invention is further configured such that, within the triangular unit, the base fabric area is located between the protrusions, and the protrusions are higher than the base fabric area.

[0007] The present invention is further configured such that the base fabric area between two adjacent triangular units along the fabric width direction has the same width as the base fabric area between two adjacent triangular units along the fabric length direction.

[0008] The present invention is further configured such that each of the triangular units includes 10 of the protrusions, and each of the protrusions is the same size.

[0009] The present invention is further configured such that, in the triangular unit, the base fabric area between two adjacent protrusions is the same size as the protrusion.

[0010] The present invention is further configured such that the fabric has a weave cycle of 70 warp yarns and 102 weft yarns, 35 warp yarns and 36 weft yarns interlaced to form the triangular unit, and the remaining warp yarns and weft yarns interlaced to form the base fabric area.

[0011] The present invention is further configured such that, in the triangular unit, each of the protrusions is formed by 5 warp yarns and 9 weft yarns interwoven, and the base fabric area between two adjacent protrusions is formed by 5 warp yarns and 9 weft yarns interwoven.

[0012] The present invention is further configured such that the fabric is formed by interlacing acetate fibers.

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

[0014] The base fabric area and triangular units are formed by the interlacing of warp and weft yarns. The triangular units are equilateral triangles formed by protrusions, thus changing the surface state of the fabric and reducing the friction generated when the fabric surface comes into contact with the outside world or the human body. Two adjacent triangular units along the width of the fabric are also arranged horizontally symmetrically with their hypotenuses facing each other. Two adjacent triangular units along the length of the fabric are also arranged horizontally symmetrically. Therefore, when the fabric generates a charge, the charge is unevenly distributed on the fabric surface, which hinders the free and continuous flow of charge on the flat fabric. This confines the charge to the protrusions, resulting in a discrete distribution of charge. When encountering a weak discharge opportunity, it is easier to dissipate locally, thereby reducing the accumulation of static electricity in the fabric. 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 5As shown, this embodiment discloses an acetate fabric. Both the warp and weft yarns of the fabric are interwoven with acetate fibers. The fabric includes a base fabric area 100 and triangular units 200. The fabric has a weave cycle of 70 warp yarns and 102 weft yarns. 35 warp yarns and 36 weft yarns interweave to form a triangular unit 200. The remaining warp and weft yarns interweave to form the base fabric area 100. In one weave cycle, warp yarns 1-70 interweave with weft yarns 1-15 and 52-66 to form the base fabric area 100. Within the interweaving range of warp yarns 1-70 with weft yarns 16-51 and 67-102, two triangular units 200 are included in the fabric width direction. Within the interweaving range of warp yarns 1-70 with weft yarns 16-51, the triangular unit 200... The 00 units are located at the intersections of warp yarns 1-35 and weft yarns 16-51, and warp yarns 36-70 and weft yarns 16-51, respectively. Triangular unit 200 is formed by interlacing warp yarns 16-20 and weft yarns 16-24, warp yarns 11-25 and weft yarns 25-33, warp yarns 6-30 and weft yarns 34-42, and warp yarns 1-35 and weft yarns 43-51 when warp yarns 1-35 interlace. Triangular unit 200 is formed by interlacing warp yarns 36-70 and weft yarns 16-24, warp yarns 41-65 and weft yarns 25-33, warp yarns 46-60 and weft yarns 34-42, and warp yarns 51-55 and weft yarns 16-70. The 43-51 weft yarns are interwoven to form the triangle unit 200 within the interweaving range of the 1-70 warp yarns and the 67-102 weft yarns. The triangle unit 200 is located at the interweaving points of the 1-35 warp yarns and the 67-102 weft yarns, and the 36-70 warp yarns and the 67-102 weft yarns. At the interweaving point of the 1-35 warp yarns and the 67-102 weft yarns, the triangle unit 200 is formed by the interweaving of the 1-35 warp yarns and the 67-75 weft yarns, the 6-30 warp yarns and the 76-84 weft yarns, the 11-25 warp yarns and the 85-93 weft yarns, and the 15-20 warp yarns and the 94-102 weft yarns. At the interweaving point of the 36-70 warp yarns and the 67-102 weft yarns, the triangle unit 200 is formed by the interweaving of the 51-55 warp yarns and the 67-75 weft yarns. The fabric is formed by interlacing warp yarns 46-60 with weft yarns 76-84, warp yarns 41-65 with weft yarns 85-93, and warp yarns 36-70 with weft yarns 94-102. Within the interlacing range of warp yarns 1-70 and weft yarns 16-51, between two triangular units 200, warp yarns 21-35 interlaced with weft yarns 16-24 to form the base fabric area 100; warp yarns 26-40 interlaced with weft yarns 25-33 to form the base fabric area 100; warp yarns 31-45 interlaced with weft yarns 34-42 to form the base fabric area 100; and warp yarns 36-50 interlaced with weft yarns 43-51 to form the base fabric area 100. Similarly, within the interlacing range of warp yarns 1-70 and weft yarns 67-102, between two triangular units 200...In this fabric, warp yarns 36-50 interweave with weft yarns 67-75 to form base fabric area 100; warp yarns 31-45 interweave with weft yarns 76-84 to form base fabric area 100; warp yarns 26-40 interweave with weft yarns 85-93 to form base fabric area 100; and warp yarns 21-35 interweave with weft yarns 94-102 to form base fabric area 100. Therefore, the area between adjacent triangular units 200 is the base fabric area 100, and each triangular unit 200 is an equilateral triangle.

[0023] Because the triangular unit 200 within the interlacing range of warp yarns 1-35 and weft yarns 16-61 uses the same weft yarns for interlacing as the triangular unit 200 within the interlacing range of warp yarns 36-70 and weft yarns 16-51, but because the uppermost part of the triangular unit 200 within the interlacing range of warp yarns 1-35 and weft yarns 16-51 is interlaced with warp yarns 1-35 and weft yarns 43-51, while the lowermost part is interlaced with warp yarns 16-20 and weft yarns 16-24, and the uppermost part of the triangular unit 200 within the interlacing range of warp yarns 36-70 and weft yarns 16-51 is interlaced with warp yarns 51-55 and weft yarns 43-51, while the lowermost part is interlaced with warp yarns 36-70 and weft yarns 16-51. Warp yarns 6-70 interweave with weft yarns 16-24. Therefore, along the fabric width, adjacent triangular units 200 are arranged in an alternating cycle, with their hypotenuses facing each other. Triangular units 200 within the interweaving range of warp yarns 1-35 and weft yarns 16-61 interweave with the same warp yarns as triangular units 200 within the interweaving range of warp yarns 1-35 and weft yarns 67-102. However, because the uppermost triangular unit 200 within the interweaving range of warp yarns 1-35 and weft yarns 16-51 interweaves with warp yarns 1-35 and weft yarns 43-51, and the lowermost triangular unit 200 interweaves with warp yarns 16-20 and weft yarns 16-24... The weft yarns interweave. Within the interweaving range of warp yarns 1-35 and weft yarns 67-102, the uppermost triangular unit 200 consists of warp yarns 16-20 interweaving with weft yarns 94-102, while the lowermost unit consists of warp yarns 1-35 interweaving with weft yarns 67-75. Similarly, the triangular units 200 within the interweaving range of warp yarns 36-70 and weft yarns 16-51 interweave with the same warp yarns as those within the same range. Finally, within the interweaving range of warp yarns 36-70 and weft yarns 16-51, the uppermost triangular unit 200 consists of warp yarns 51-55 interweaving with weft yarns 43-51. The fabric is woven in a pattern where the 36th to 70th warp yarns interweave with the 16th to 24th weft yarns at the bottom. Within the interweaving range of the 36th to 70th warp yarns and the 67th to 102nd weft yarns, the uppermost triangular unit 200 interweaves the 36th to 70th warp yarns with the 94th to 102nd weft yarns, and the lowermost unit interweaves the 51st to 55th warp yarns with the 67th to 75th weft yarns. Therefore, two alternating triangular units 200 form a group, and adjacent groups of triangular units 200 are arranged in a horizontally symmetrical cycle along the length of the fabric. Thus, the triangular structure of the triangular unit 200 can maintain its shape in time when the fabric is subjected to external forces such as stretching and friction, reducing fabric deformation and avoiding a decrease in fabric performance.

[0024] In the triangular unit 200 formed by the interlacing of warp yarns 1-35 and weft yarns 16-51, warp yarns 16-20 and weft yarns 16-24 interlaced to form a protrusion 201; warp yarns 11-15 and 21-25 interlaced with weft yarns 25-33 to form a protrusion 201; warp yarns 6-10, 16-20, and 26-30 interlaced with weft yarns 34-42 to form a protrusion 201; and warp yarns 1-5 and 11-15... Warp yarns, warp yarns 21-25, and warp yarns 31-35 interweave with weft yarns 43-51 to form protrusion 201, while warp yarns 16-20 interweave with weft yarns 25-33 to form base fabric area 100; warp yarns 11-15, warp yarns 21-25, and weft yarns 34-42 interweave to form base fabric area 100; warp yarns 6-10, warp yarns 16-20, and warp yarns 26-30 interweave with weft yarns 43-51 to form base fabric area; and warp yarns 36- The arrangement of protrusions 201 in the triangular unit 200 formed by the interlacing of warp 70 and weft yarns 16-51 is horizontally symmetrical to that in the triangular unit 200 formed by the interlacing of warp 1-35 and weft yarns 16-51. Similarly, the arrangement of protrusions 201 in the triangular unit 200 formed by the interlacing of warp 1-35 and weft yarns 67-102 is horizontally symmetrical to that in the triangular unit 200 formed by the interlacing of warp 1-35 and weft yarns 16-51. The arrangement of protrusions 201 in the triangular unit 200 formed by the interlacing of warp 36-70 and weft yarns 67-102 is the same as that in the triangular unit 200 formed by the interlacing of warp 1-35 and weft yarns 16-51. Therefore, one triangular unit 200 includes multiple protrusions 201, and the protrusions 201 are arranged along the fabric length in a ratio of 1:2:3:4 or 4:3:2:1. (Refer to...) Figure 4 , Figure 5In the triangular unit 200, the protrusions 201 are arranged in a 1:2:3:4 ratio along the fabric length. Centered on the triangular unit 200 arranged in a 1:2:3:4 ratio, the protrusions 201 of the surrounding triangular units 200 are arranged in a 4:3:2:1 ratio along the fabric length. Because each protrusion 201 is located within the triangular unit 200, it is formed by the interlacing of 5 warp yarns and 9 weft yarns. The base fabric area 100 between two adjacent protrusions 201 is also formed by the interlacing of 5 warp yarns and 9 weft yarns. Therefore, each triangular unit 200 includes 10 protrusions. Block 201, and each protrusion 201 is the same size. Located in triangular unit 200, the base fabric area 100 between two adjacent protrusions 201 is the same size as the protrusion 201. The width of the base fabric area 100 between two protrusions 201 is the width of 5 warp yarns. The width of the protrusions 201 along the fabric width direction is the same. The length of the base fabric area 100 between two protrusions 201 is the length of 9 weft yarns. The length of the protrusions 201 along the fabric length direction is the same. Because the structure of the protrusions 201 is three-up, three-down, the base fabric area 100... The weave is top-bottom, so the density of the warp and weft yarns in the base fabric area 100 after interlacing is greater than that in the protrusions 201. Therefore, the protrusions 201 are compressed and raised due to the greater density of the warp and weft yarns in the base fabric area 100, and are thus located within the triangular unit 200. The base fabric area 100 is between the protrusions 201, and the protrusions 201 are higher than the base fabric area 100. Therefore, the protrusions 201 alter the smoothness of the fabric surface, increasing its unevenness. This reduces static electricity generated by friction by decreasing the contact area. The structure of the bumps 201 affects the distribution of charge. Compared to a flat fabric surface, the bumps 201 hinder the free and continuous flow of charge, making it easier for charge to accumulate at the bumps 201 and form a tip effect. Since there is a base fabric area 100 between each bump 201 in a triangular unit 200, the bumps 201 are discretely distributed in the triangular unit 200. Therefore, when the charge accumulates at the bumps 201, the charge is also discretely distributed. Thus, when the fabric comes into contact with a weak discharge opportunity, the charge is more easily dissipated locally.

[0025] Because the base fabric area 100 between two triangular units 200 along the fabric width direction is the distance of 15 warp yarns, and the base fabric area 100 between two triangular units 200 along the fabric length direction is the distance of 15 weft yarns, the width of the base fabric area 100 between two adjacent triangular units 200 along the fabric width direction is the same as that between two adjacent triangular units 200 along the fabric length direction. Since the protrusion 201 is higher than the base fabric area 100, the base fabric area 100 on the front side of the fabric is concave, and the protrusion 201 on the back side of the fabric is also concave. This reduces the contact area of ​​the fabric and reduces friction. At the same time, the concave area strengthens the air gap between the fabric and the friction surface, thereby consuming part of the static charge through the water vapor in the airflow.
