Description

Technical Field

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

[0002] Most existing leather coatings use flat-structured base fabrics. Because flat-structured base fabrics are relatively smooth, the adhesion between the leather coating and the base fabric is not strong, so the leather coating is easy to peel off from the base fabric after a long period of use. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a composite base fabric. The base fabric is formed by interlacing warp and weft yarns to create an outer and inner layer. The outer layer includes a first region, a second region, a third region, and a fourth region. The second and third regions each form a structure with a central depression and raised sides. The height of the raised sections in the second and third regions is the same as the height of the first region, while the height of the depression in the second and third regions is the same as the height of the fourth region. This creates an uneven structure on the base fabric surface. When the leather coating cures on the uneven surface, it fills the depressions of the base fabric and wraps around the raised parts, thus enhancing the adhesion between the leather coating and the base fabric. The fourth region forms pores, allowing the leather coating to penetrate into the inner layer and bond with both layers of the base fabric, thereby increasing the adhesion of the leather coating to the base fabric.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a composite base fabric comprising a surface layer and an inner layer from the outside to the inside; the surface layer comprising a first region, a second region, a third region, and a fourth region; the second region comprising a transversely recessed region and transversely protruding regions located on both sides of the transversely recessed region; the third region comprising a longitudinally recessed region and longitudinally protruding regions located on both sides of the longitudinally recessed region; the height of the first region being the same as the height of the transversely protruding regions and the longitudinally protruding regions; and the height of the fourth region being the same as the height of the transversely recessed regions and the longitudinally recessed regions; the fourth region comprising a first unit and a plurality of holes.

[0005] The present invention is further configured such that, along the width direction of the base fabric, the first region and the second region are arranged alternately, and the third region and the fourth region are arranged alternately; along the length direction of the base fabric, the first region and the third region are arranged alternately, and the second region and the fourth region are arranged alternately.

[0006] The present invention is further configured such that the outer layer and the inner layer are connected by a connection point.

[0007] The present invention is further configured such that the first region, the second region, the third region, and the fourth region are of equal size.

[0008] The present invention is further configured such that, in the second region, the transverse recessed area and the transverse protruding area are arranged along the length direction of the base fabric, and in the third region, the longitudinal recessed area and the longitudinal protruding area are arranged along the width direction of the base fabric.

[0009] The present invention is further configured such that the size of the transverse recessed area is equal to that of the longitudinal recessed area, and the size of the transverse protrusion area is equal to that of the longitudinal protrusion area.

[0010] The present invention is further configured such that the fourth region includes four holes.

[0011] The present invention is further configured such that the base fabric has an 80-warp-80-weft weave as one weave cycle, the odd number of warp yarns in the 80 warp yarns and the odd number of weft yarns in the 80 weft yarns interweave to form the outer layer, and the even number of warp yarns in the 80 warp yarns and the even number of weft yarns in the 80 weft yarns interweave to form the inner layer.

[0012] The present invention is further configured such that the first region, the second region, the third region and the fourth region are all formed by 20 warp yarns and 20 weft yarns interwoven together.

[0013] The present invention is further configured such that the odd number of warp yarns in the first 40 warp yarns interweaves with the odd number of weft yarns in the first 40 weft yarns to form the first region, the odd number of warp yarns in the 41st to 80 warp yarns interweaves with the odd number of weft yarns in the first 40 weft yarns to form the second region, the odd number of warp yarns in the first 40 warp yarns interweaves with the odd number of weft yarns in the 41st to 80 weft yarns to form the third region, and the odd number of warp yarns in the 41st to 80 warp yarns interweaves with the odd number of weft yarns in the 41st to 80 weft yarns to form the fourth region.

[0014] In summary, this utility model has the following beneficial effects:

[0015] The base fabric, consisting of an outer and inner layer, is formed by interlacing warp and weft yarns. The second and third regions of the outer layer are both concave in the middle and convex on both sides. The height of the convex regions in the second and third regions is the same as the height of the first region, and the height of the concave regions in the second and third regions is the same as the height of the fourth region. This creates an uneven structure on the surface of the base fabric. When the leather coating cures, the concave areas are filled and the convex parts are wrapped, thus increasing the adhesion between the leather coating and the base fabric. The pores on the surface of the fourth region allow the leather coating to penetrate into the inner layer, further increasing the adhesion between the leather coating and the inner layer, thereby reducing the peeling of the leather coating from the base fabric.

Detailed Implementation

[0023] 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.

[0024] like Figure 1 — Figure 6As shown, this embodiment discloses a composite base fabric. The base fabric has an 80-warp and 80-weft yarn weave as one weave cycle. The odd number of warp yarns and the odd number of weft yarns among the 80 warp yarns interweave to form the outer layer 100, and the even number of warp yarns and the even number of weft yarns among the 80 warp yarns interweave to form the inner layer 200. Therefore, the base fabric includes the outer layer 100 and the inner layer 200 from the outside to the inside. Within the range of warp and weft yarns interweaving to form the outer layer 100, the odd number of warp yarns from the 1st to the 40th warp yarns interweaves with the odd number of weft yarns from the 1st to the 40th weft yarns to form the first zone. Region 101, the odd-numbered warp yarns of warp yarns 41-80 interweave with the odd-numbered weft yarns of weft yarns 1-40 to form a second region 102, the odd-numbered warp yarns of warp yarns 1-40 interweave with the odd-numbered weft yarns of weft yarns 41-80 to form a third region 103, and the odd-numbered warp yarns of warp yarns 41-80 interweave with the odd-numbered weft yarns of weft yarns 41-80 to form a fourth region 104. Therefore, surface layer 100 includes a first region 101, a second region 102, a third region 103, and a fourth region 104, and the first region 101, the second region 102, the second region 103, the third region 104, the fourth region 104, and the fourth region 102. 02. Both the third region 103 and the fourth region 104 are formed by 20 warp yarns and 20 weft yarns interlacing. Therefore, the first region 101, the second region 102, the third region 103, and the fourth region 104 are of equal size. The first region 101 and the second region 102 are interlaced with the same weft yarns, and the third region 103 and the fourth region 102 are interlaced with the same weft yarns. Therefore, along the width of the base fabric, the first region 101 and the second region 102 alternate, and the third region 103 and the fourth region 104 alternate. The first region... Regions 101 and 103 are interwoven with the same warp yarns, and regions 102 and 104 are interwoven with the same warp yarns. Therefore, along the length of the base fabric, regions 101 and 103 are arranged alternately, and regions 102 and 104 are arranged alternately. Thus, the different weave structures of the four regions form areas of the same size, thereby increasing the structural stability of the surface layer 100. Therefore, when the leather coating is applied, the stable base fabric structure prevents the base fabric from deforming, thereby improving the dimensional stability of the overall composite base fabric.

[0025] Located in the second region 102, the odd-numbered warp yarns from warp yarns 41-80 interweave with the odd-numbered weft yarns from weft yarns 1-40. The odd-numbered warp yarns from warp yarns 41-80 interweave with weft yarns 15, 17, 19, 21, 23, and 25 in a plain weave, while the odd-numbered warp yarns from warp yarns 41-80 interweave with weft yarns 1, 3, 5, 7, 9, 11, 13, 27, 29, 31, 33, 35, 37, and 39 in a ribbed weave. Therefore, the intersection of the odd-numbered warp yarns from warp yarns 41-80 with weft yarns 15, 17, 19, 21, 23, and 25 is lower than the intersection of the odd-numbered warp yarns from warp yarns 41-80 with weft yarns 1, 3, 5, 7, 9, 11, and 1... At the intersection of weft yarns 3, 27, 29, 31, 33, 35, 37, and 39, the odd-numbered warp yarns of warp yarns 41-80 interweave with the weft yarns 15, 17, 19, 21, 23, and 25 to form a transverse concave area 1022. The odd-numbered warp yarns of warp yarns 41-80 interweave with the weft yarns 1, 3, 5, 7, 9, 11, 13, 27, 29, 31, 33, 35, 37, and 39 to form a transverse convex area 1021. Since the weft yarns of the transverse concave area 1022 are located in the middle of the weft yarns of the transverse convex area 1021, the second region 102 includes the transverse concave area 1022 and the transverse convex areas 1021 located on both sides of the transverse concave area 1022.

[0026] Located in the third region 103, the odd-numbered warp yarns of warp yarns 1-41 interweave with the odd-numbered weft yarns of weft yarns 41-80. The odd-numbered weft yarns of weft yarns 41-80 interweave with warp yarns 15, 17, 19, 21, 23, and 25 in a plain weave, while the odd-numbered weft yarns of weft yarns 41-80 interweave with warp yarns 1, 3, 5, 7, 9, 11, 13, 27, 29, 31, 33, 35, 37, and 39 in a ribbed weave. Therefore, the intersection of the odd-numbered weft yarns of weft yarns 41-80 with warp yarns 15, 17, 19, 21, 23, and 25 is lower than the intersection of the odd-numbered weft yarns of weft yarns 41-80 with warp yarns 1, 3, 5, 7, 9, 11, and 1... At the intersection of warp yarns 3, 27, 29, 31, 33, 35, 37, and 39, the odd-numbered weft yarns of weft yarns 41-80 interweave with warp yarns 15, 17, 19, 21, 23, and 25 to form a longitudinal concave area 1032. Meanwhile, the odd-numbered weft yarns of weft yarns 41-80 interweave with warp yarns 1, 3, 5, 7, 9, 11, 13, 27, 29, 31, 33, 35, 37, and 39 to form a longitudinal convex area 1031. Since the warp yarns of the longitudinal concave area 1032 are located in the middle of the warp yarns of the longitudinal convex area 1031, the third region 103 includes the longitudinal concave area 1032 and the longitudinal convex area 1031 located in both longitudinal concave areas 1032.

[0027] In the first region 101, the odd-numbered warp yarns of warp yarns 1-41 interweave with the odd-numbered weft yarns of weft yarns 1-41 in a 3-up-1-down weave. In the fourth region 104, the odd-numbered warp yarns of warp yarns 41-80 interweave with the odd-numbered weft yarns of weft yarns 41-80 in a plain weave, alternating with a 5-up-5-down weave. Because the weave structure of the first region 101 is the same as the longitudinal raised stripe weave in the third region 103 and the transverse raised stripe weave in the second region 102, the height of the first region 101 is the same as that of the transverse raised area 1021 and the longitudinal raised area 1021. The raised areas 1031 have the same height. Since the structure of the fourth area 104 is the same as the plain weave in the second area 102 and the plain weave in the third area 102, the height of the fourth area 104 is the same as the height of the transverse recessed area 1022 and the longitudinal recessed area 1032. This creates a textured structure on the base fabric surface 100. The uneven structure of the base fabric surface allows the leather coating material to fill the recesses of the base fabric and wrap the raised parts when the leather coating is cured on the textured surface, thus increasing the adhesion between the leather coating and the base fabric.

[0028] Located in the second region 102, because the odd-numbered warp yarns of warp yarns 41-80 interweave with the weft yarns 15, 17, 19, 21, 23, and 25 to form a transverse concave region 1022, and the odd-numbered warp yarns of warp yarns 41-80 interweave with the weft yarns 1, 3, 5, 7, 9, 11, 13, 27, 29, 31, 33, 35, 37, and 39 to form a transverse convex region 1021, the transverse concave region 1022 and the transverse convex region 1021 are made of the same warp yarns but different weft yarns, therefore they are located in the second region 102. In the middle, the transverse concave area 1022 and the transverse convex area 1021 are arranged along the length of the base fabric. Located in the third region 103, because the odd-numbered weft yarns of the 41st to 80th weft yarns interweave with the 15th, 17th, 19th, 21st, 23rd, and 25th warp yarns to form the longitudinal concave area 1032, and the odd-numbered weft yarns of the 41st to 80th weft yarns interweave with the 1st, 3rd, 5th, 7th, 9th, 11th, 13th, 27th, 29th, 31st, 33rd, 35th, 37th, and 39th warp yarns to form the longitudinal convex area 1031, the longitudinal concave area 103... Region 2, which shares the same weft yarn as the longitudinal raised area 1031 but uses different warp yarns, is therefore located in the third region 103. The longitudinal recessed area 1032 and the longitudinal raised area 1031 are arranged along the width of the base fabric. Since the transverse recessed area 1022 is the width of 20 warp yarns and the length of 6 weft yarns, while the longitudinal recessed area 1032 is the width of 6 warp yarns and the length of 20 weft yarns, the transverse recessed area 1022 and the longitudinal recessed area 1032 are of equal size. The transverse raised area 1021 is the width of 20 warp yarns and the length of 7 weft yarns. The length of the yarn, the longitudinal raised area 1031 is the width of 7 warp yarns and the length of 20 weft yarns, so the size of the transverse raised area 1021 is equal to that of the longitudinal raised area 1031. Because the arrangement directions in the second area 102 and the third area 103 are different, the structure is more stable when the second area 102 and the third area 103 connect the first area 101 and the fourth area 104. At the same time, because the directions are different, the surface layer 100 can adapt to external forces in multiple directions. Therefore, when covered with leather coating, the overall structure of the base fabric is more stable.

[0029] Because the outer layer 100 and the inner layer 200 are connected by the interlacing of the 1st warp yarn and the 2nd and 80th weft yarns, the 19th warp yarn and the 20th and 60th weft yarns, the 39th warp yarn and the 40th weft yarn, the 59th warp yarn and the 20th and 60th weft yarns, and the 79th warp yarn and the 2nd and 80th weft yarns, and because they are located in the fourth region 104, because the 41st, 43rd, 45th, and 47th warp yarns... The weave of warp yarn 49 interlaced with weft yarns 41, 43, 45, 47, and 49 is the same as the weave of warp yarns 51, 53, 55, 57, and 59 interlaced with weft yarns 51, 53, 55, 57, and 59. Conversely, the weave of warp yarns 41, 43, 45, 47, and 49 interlaced with weft yarns 51, 53, 55, 57, and 59 is the same as the weave of warp yarns 51, 53, 55, 57, and 59 interlaced with weft yarns 41, 43, 45, 47, and 49. Therefore, in... The warp yarns 41, 43, 45, 47, 49, 51, 53, 55, 57, and 59, along with the weft yarns 41, 43, 45, 47, 49, 51, 53, 55, 57, and 59, are interwoven to create internal yarn stress, thus forming eyelets 1042. The remaining areas are interwoven to form the first region 1041. Therefore, the fourth region 104 includes the first unit 1041 and multiple eyelets 1042, because the fourth region 104 consists of 20 warp yarns and 20 weft yarns interwoven. The fabric is woven in such a way that every 10 warp yarns and 10 weft yarns interweave to form an eyelet 1042. Therefore, the fourth region 104 includes 4 eyelets 1042. Since the outer layer 100 and the inner layer 200 are connected by a joint, when the base fabric is covered with a leather coating, the leather coating will penetrate into the inner layer 200 before the surface cures. This increases the adhesion points of the leather coating in the inner layer, thereby strengthening the adhesion between the base fabric and the leather coating and reducing the peeling between the leather coating and the base fabric.
