A type of leather fabric

Abstract

This utility model discloses a leather fabric comprising a base fabric and wavy protrusions. Along the length of the fabric, the base fabric and wavy protrusions are arranged alternately and cyclically. Along the length of the fabric, in two adjacent wavy protrusions, the crest of one wavy protrusion faces the trough of the other. The curved surface of the base fabric and the curved surface of the wavy protrusions are complementary. The thickness D1 of the wavy protrusions is greater than the thickness D2 of the base fabric, and the crest width H1 of the base fabric is greater than the crest width H2 of the wavy protrusions. In this utility model, the warp and weft yarns interweave to form the base fabric and wavy protrusions. The wavy protrusions are discontinuous along the length of the fabric, with a base fabric thickness of half its length between adjacent wavy protrusions. Both the base fabric and the wavy protrusions are curved, allowing the leather fabric to adapt to bending in the width direction. Simultaneously, the wavy protrusions are higher than the base fabric, allowing the leather fabric to adapt to bending in the length direction, thereby reducing the bending stiffness of the fabric.

Description

Technical Field

[0001] This utility model relates to the field of textiles, and more specifically, to a leather fabric. Background Technology

[0002] Most existing leather fabric bases have a flat fabric structure, resulting in high hardness of the base fabric and surface leather coating. This makes it difficult for the leather fabric to bend, leading to overall stiffness of the fabric. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a leather fabric in which warp and weft yarns interweave to form a base fabric and wavy protrusions. The wavy protrusions are discontinuous along the length of the fabric, and the base fabric with a thickness of half the thickness of the wavy protrusions is between two adjacent wavy protrusions. Both the base fabric and the wavy protrusions are curved, so that the leather fabric can adapt to bending in the width direction of the fabric. At the same time, the wavy protrusions are higher than the base fabric, so that the leather fabric can adapt to bending in the length direction of the fabric, thereby reducing the bending stiffness of the fabric. Since the thickness of the base fabric is thinner than the thickness of the wavy protrusions, the wavy protrusions increase the surface area of ​​the fabric and increase the deformation generated under stress, thereby increasing the flexibility of the fabric. Furthermore, the width of the curved surface of the base fabric is slightly larger than the width of the curved surface of the wavy protrusions, so that the base fabric provides space for the deformation of the wavy protrusions, thereby keeping the wavy protrusions stable.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a leather fabric comprising a base fabric and wavy protrusions, wherein the base fabric and the wavy protrusions are arranged alternately and cyclically along the length of the fabric, wherein in two adjacent wavy protrusions, the crest of one wavy protrusion is opposite to the trough of the other wavy protrusion, the curved surface of the base fabric and the curved surface of the wavy protrusion are complementary, the thickness D1 of the wavy protrusion is greater than the thickness D2 of the base fabric, and the crest width H1 of the base fabric is greater than the crest width H2 of the wavy protrusion.

[0005] The present invention is further configured such that the thickness D1 of the wave protrusion is twice the thickness D2 of the base fabric.

[0006] The present invention is further configured such that the wave protrusions are higher than the base fabric.

[0007] The present invention is further configured such that the crest tilt angle α of the base fabric is greater than the crest tilt angle β of the wave protrusion.

[0008] The present invention is further configured such that the fabric is woven with 44 warp yarns and 24 weft yarns in one weave cycle, the 44 warp yarns and 7 weft yarns interweave to form the wave protrusion, and the 44 warp yarns and the 10th weft yarn interweave to form the base fabric.

[0009] The present invention is further configured such that the crest of the wave protrusion is the width of 7 weft yarns, and the trough of the wave protrusion is the width of 2 weft yarns.

[0010] The present invention is further configured such that the crest of the base fabric is the width of 10 weft yarns, and the trough of the base fabric is the width of 5 weft yarns.

[0011] The present invention is further configured such that the base fabric and the wavy raised surface are coated with a leather coating.

[0012] In summary, this utility model has the following beneficial effects:

[0013] The base fabric and wave protrusions are formed by the interlacing of warp and weft yarns. Therefore, both the base fabric and the wave protrusions are curved surfaces. The wave protrusions are discontinuous along the length of the fabric, and the base fabric, which is half the thickness of the wave protrusion, connects the individual wave protrusions. Therefore, when the fabric is bent, the wave protrusions increase the surface area of ​​the fabric through their curved structure, thereby bearing and dispersing some of the pressure. The base fabric increases the deformation space for the wave protrusions, allowing the internal yarns to move and increasing the overall deformation of the fabric, thus increasing the fabric's flexibility. Furthermore, the curved width of the base fabric area is slightly larger than that of the wave protrusions, providing a stable foundation and making the wave protrusions more stable under stress. This makes the leather fabric easier to bend, fold, and twist. Attached Figure Description

[0019] 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.

[0020] like Figure 1 — Figure 4As shown, this embodiment discloses a leather fabric. The fabric is woven with 44 warp yarns and 24 weft yarns in one weave cycle. The 44 warp yarns and 7 weft yarns interweave to form a wave-like protrusion 2, and the 44 warp yarns and the 10th weft yarn interweave to form a base fabric 1. Therefore, the fabric includes a base fabric 1 and wave-like protrusions 2. The surfaces of the base fabric 1 and wave-like protrusions 2 are covered with a leather coating. In one weave cycle, there are two base fabrics 1 and two wave-like protrusions 2. One base fabric 1 and wave-like protrusion 2 is located within the interweaving range of the 1st to 44th warp yarns and the 1st to 12th weft yarns, and the other base fabric 1 and wave-like protrusion 2 is located within the interweaving range of the 1st to 44th warp yarns and the 13th to 24th weft yarns. The 1st and 2nd weft yarns interweave with the 1st to 44th warp yarns. The weft yarn interweaves with warp yarns 5-43, the weft yarn 4 interweaves with warp yarns 10-40, the weft yarn 5 interweaves with warp yarns 15-37, the weft yarn 6 interweaves with warp yarns 20-34, and the weft yarn 7 interweaves with warp yarns 21-35 to form wave bulge 2. The weft yarn 3 interweaves with warp yarns 1-4 and 44, the weft yarn 4 interweaves with warp yarns 1-9 and 41-44, the weft yarn 5 interweaves with warp yarns 1-14 and 38-44, the weft yarn 6 interweaves with warp yarns 1-19 and 35-44, the weft yarn 7 interweaves with warp yarns 1-20 and 36-44, and the weft yarns 8-12 interweave with warp yarns 1-44 to form base fabric 1, located within the interweaving of warp yarns 1-44 and weft yarns 13-24. 3. The 14th weft yarn interweaves with warp yarns 1-44; the 15th weft yarn interweaves with warp yarns 1-27 and 33-44; the 16th weft yarn interweaves with warp yarns 1-24 and 38-44; the 17th weft yarn interweaves with warp yarns 1-21 and 43-44; the 18th weft yarn interweaves with warp yarns 4-18; the 19th weft yarn interweaves with warp yarns 5-19 to form wave bulge 2; the 15th weft yarn interweaves with warp yarns 28-32; the 16th weft yarn interweaves with warp yarns 25-37; the 17th weft yarn interweaves with warp yarns 22-42; the 18th weft yarn interweaves with warp yarns 1-3 and 19-44; the 19th weft yarn interweaves with warp yarns 1-4 and 20-44; the 20th-24th weft yarn interweaves with warp yarns 1-44 to form wave bulge 2. The base fabric 1 and the wavy protrusions 2 are interwoven along the weft direction. Therefore, along the fabric length, base fabric 1 and wavy protrusions 2 alternate in a cyclical arrangement. Since the warp and weft yarns of base fabric 1 interweave in a 1-up-1-down pattern, while the warp and weft yarns of wavy protrusions 2 interweave in a 3-up-1-down pattern laterally, the warp and weft yarns are interwoven at the same density, making wavy protrusions 2 higher than base fabric 1. Furthermore, because base fabric 1 has a 1-up-1-down pattern while wavy protrusions 2 have a 3-up-1-down pattern, a single weft pattern of wavy protrusions 2 consists of 4 warp and 4 weft yarns per cycle, while base fabric 1 has 2 warp and 2 weft yarns per cycle. Therefore, the thickness D1 of wavy protrusions 2 is greater than the thickness D2 of base fabric 1, and the thickness D1 of wavy protrusions 2 is twice the thickness D2 of base fabric 1.Therefore, when folding or bending along the length of the fabric, the base fabric 1 is thinner than and lower than the corrugated bulge 2, making it easier to fold or bend, thus reducing the overall bending rigidity of the fabric along its length.

[0021] Because in one weft cycle, the 1st and 2nd weft yarns interweave with the 1st to 44th warp yarns, the 3rd weft yarn interweaves with the 5th to 43rd warp yarns, the 4th weft yarn interweaves with the 10th to 40th warp yarns, the 5th weft yarn interweaves with the 15th to 37th warp yarns, the 6th weft yarn interweaves with the 20th to 34th warp yarns, and the 7th weft yarn interweaves with the 21st to 35th warp yarns, forming wave bulge 2. The crest of wave bulge 2 is located at the intersection of the 7th weft yarn and the 21st to 35th warp yarns, and the trough of wave bulge 2 is located at the intersection of the 1st and 2nd weft yarns and the 1st to 44th warp yarns. At the intersections of warp yarns 2, 43, and 44, weft yarns 13 and 14 interweave with warp yarns 1-44; weft yarn 15 interweaves with warp yarns 1-27 and 33-44; weft yarn 16 interweaves with warp yarns 1-24 and 38-44; weft yarn 17 interweaves with warp yarns 1-21 and 43-44; weft yarn 18 interweaves with warp yarns 4-18; and weft yarn 19 interweaves with warp yarns 5-19, forming wave bulge 2. The crest of wave bulge 2 is located at the intersection of weft yarn 19 and warp yarns 4-44. The wave ridge 2 is formed at the interlacing points of warp yarns 5-19. The trough of wave ridge 2 is located at the interlacing points of weft yarns 13 and 14 with warp yarns 27-30. Along the fabric length, in two adjacent wave ridges 2, the crest of one wave ridge 2 is opposite the trough of the other. Between two wave ridges 2, weft yarn 3 interlacs with warp yarns 1-4 and 44, weft yarn 4 interlacs with warp yarns 1-9 and 41-44, and weft yarn 5 interlacs with warp yarns 1-14 and 38-44. The base fabric 1 is formed by interlacing the 6th weft yarn with the 1st to 19th warp yarns and the 35th to 44th warp yarns, the 7th weft yarn with the 1st to 20th warp yarns and the 36th to 44th warp yarns, and the 8th to 12th weft yarns with the 1st to 44th warp yarns. Therefore, the curved surface of the base fabric 1 and the curved surface of the wavy protrusion 2 complement each other. Thus, when folded or bent along the width of the fabric, the curved surfaces of the base fabric 1 and the wavy protrusion 2 are more likely to adapt to bending deformation in the width of the fabric, thereby reducing the overall bending rigidity of the fabric in the width direction.

[0022] Because the highest point of wave 2 is located at the intersection of the 7th weft yarn and the 21st-35th warp yarns, and at the intersection of the 19th weft yarn and the 5th-19th warp yarns, while the lowest point of wave 2 is located at the intersection of the 1st and 2nd weft yarns and the 1st, 2nd, 43rd, and 44th warp yarns, and at the intersection of the 13th and 14th weft yarns and the 27th-30th warp yarns, the peak of wave 2 is the width of 7 weft yarns, and the trough of wave 2 is the width of 2 weft yarns. The width of the base fabric 1 is such that the highest point of the wave crest is located at the intersection of the 3rd weft yarn and the 44th, 1st, 2nd, 3rd, and 4th warp yarns, and at the intersection of the 15th weft yarn and the 28th-32nd warp yarns. The lowest point of the wave trough of base fabric 1 is located at the intersection of the 8th weft yarn and the 20th-35th warp yarns, and at the intersection of the 20th weft yarn and the 5th-19th warp yarns. Therefore, the wave crest of base fabric 1 is the width of 10 weft yarns, and the wave trough of base fabric 1 is the width of 5 weft yarns. The crest width H1 of the base fabric 1 is greater than the crest width H2 of the wave protrusion 2. Since the crest of wave protrusion 2 is 15 warp yarns wide, while the wave of base fabric 1 is 5 warp yarns wide, the crest inclination angle α of base fabric 1 is greater than the crest inclination angle β of wave protrusion 2. Furthermore, the thickness of base fabric 1 is thinner than that of the wave protrusion. Therefore, when the fabric is bent or folded, the yarns of wave protrusion 2 will move. This movement of the yarns of wave protrusion 2 within a limited range via base fabric 1 allows wave protrusion 2 to adapt to fabric deformation without exceeding this limited range, thus maintaining continuous stability. Simultaneously, because wave protrusion 2 and base fabric 1 form a concave-convex structure that increases the fabric surface area, when a leather coating is applied to the fabric surface, anchor points are added between the coating and the fabric, allowing the leather coating to stretch with the fabric and maintain the overall stability of the fabric.
