Description

Technical Field

[0001] The invention belongs to the technical field of clothing fabric weaving, and specifically relates to a warp knitted jacquard fabric which dynamically displays patterns as the tensile strength changes. Background Art

[0002] In the history of the development of knitted clothing fabrics, especially in the field of warp knitting, fabrics have made great improvements in appearance and function. However, with the progress of society, the development of science and technology, the improvement of the types and functions of textile raw materials, and especially the increasing requirements of people on the appearance and comfort of ready-made clothes, the diversity, environmental protection and functionality of existing warp knitted fabrics are slightly insufficient. Therefore, the consumer market is eager for more and better new warp knitted fabrics to make up for some of the shortcomings of existing fabrics.

[0003] In order to enrich the diversity of fabrics, many designers and manufacturers have spent a lot of effort on the appearance of fabrics and have achieved certain results.

[0004] CN 209619583 U (a color-changing jacquard mesh cloth) comprises a first jacquard lace layer, a first color-changing layer, an intermediate layer, a second color-changing layer and a second jacquard lace layer; the first color-changing layer is arranged between the first jacquard lace layer and the intermediate layer, and the second color-changing layer is arranged between the second jacquard lace layer and the intermediate layer; the first jacquard lace layer is formed by interweaving the upper surface of the first color-changing layer through a jacquard weaving process, the second jacquard lace layer is formed by interweaving the lower surface of the second color-changing layer through a jacquard weaving process, and the lower surface of the first color-changing layer and the upper surface of the second color-changing layer are interwoven and connected by the binding yarn of the intermediate layer through a warp knitting process, thereby realizing the connection of each layer. The reflective surface with a right-angle triangle structure is used to provide light emission on the surface, so as to achieve the purpose of improving the color-changing performance of the mesh cloth.

[0005] CN 108691088 B (Weaving method of warp knitted jacquard three-color jacquard fabric) relates to a weaving method of warp knitted jacquard three-color jacquard fabric. The weaving method is used to weave a three-color jacquard fabric, including an A-color pattern area, a B-color pattern area, a C-color base mesh area, a pattern outline area and an elastic area, so as to realize the production of a three-color decorative jacquard pattern fabric with a fine texture and thinness.

[0006] CN 202175822 U (Multi-bar warp knitted jacquard fabric) discloses a multi-bar warp knitted jacquard fabric, including a bottom mesh layer woven from ground yarn and jacquard yarn, and a weft yarn jacquard layer and a pressed yarn jacquard layer are distributed on the technical reverse side of the bottom mesh layer. Spandex yarn is also provided in the bottom mesh layer. Since the weft yarn jacquard structure is arranged on the jacquard yarn in the above structure, the pressed yarn jacquard structure and the weft yarn jacquard structure on the same piece of fabric protrude from the front side of the fabric, forming the coexistence of the pressed yarn structure protrusion and the weft yarn structure protrusion. Therefore, a warp knitted fabric with excellent convex and concave feeling, three-dimensional effect and relief effect can be provided.

[0007] In summary, CN 209619583 U highlights the color-changing performance from an optical perspective, CN 108691088 B utilizes the interweaving of different yarns to make different areas of the fabric present different colors, and CN 202175822 U utilizes the characteristics of the loom to provide a three-dimensional fabric. These are all fabrics whose fabric properties can be intuitively seen from the appearance, but there is no report of a warp knitted fabric with an invisible effect in which the pattern and mesh can be hidden in a free state but can be immediately revealed when stretched by an external force.

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] As attached Figure 1-5 As shown, the present invention discloses a warp knitted jacquard fabric that dynamically displays a pattern as the tensile strength changes, including a fabric body, the fabric body including a pattern layer and a skin-contacting layer, the pattern layer being connected to the outer surface of the skin-contacting layer, the pattern layer including a dense structure area and a mesh structure area, the skin-contacting layer is woven to form a number of dense areas that are not less than the mesh structure area on the pattern layer, the dense area on the skin-contacting layer corresponds to the mesh structure area on the pattern layer, the mesh structure area of ​​the pattern layer is hidden when the fabric body is not stretched and does not show the mesh shape, and the mesh structure area of ​​the pattern layer will be revealed after the fabric body is stretched. The mesh structure area can be a mesh or a pattern, which is a pore structure, the pattern layer is woven and formed by elastic yarn, the mesh structure area of ​​the fabric body can be hidden when it is in a free state, and the whole is consistent with the dense structure area when viewed from the outside. It can appear immediately when stretched by external force, and has the characteristics of dynamically showing the appearance effect of the pattern as the tensile strength changes, that is, it will present different shapes when subjected to different pulling forces. Since the dense area arranged on the skin-contacting layer covers the mesh structure area, the fabric body will not be hollowed out as a whole after being stretched. Other structural layers can be woven between the skin-contacting layer and the pattern layer to meet the needs.

[0028] The mesh structure area on the pattern layer can be set to multiple, and can be arranged at intervals, or arranged in a certain order, or arranged in disorder. When the mesh structure is a mesh, it can be polygonal, circular, or other shapes.

[0029] The pattern layer and the skin-contacting layer are formed into an integrated structure during the weaving process.

[0030] The pattern layer is formed by weaving yarn Y1 and yarn Y2 as jacquard yarns, and the skin-contacting layer is formed by weaving yarn Y3 as base yarn. When necessary, multiple groups of yarns can be added for weaving together.

[0031] The pattern layer formed by the yarn Y1 and the yarn Y2 has at least one dense area and one mesh area, the digital structure of the inlay yarn of Y1 is a deformation of 1-0 / 1-2 / / , and the digital structure of the inlay yarn of Y2 is a deformation of 1-2 / 1-0 / / .

[0032] The yarn Y3 is woven to form at least one dense area, which covers the mesh structure area formed by the yarn Y1, and the digital structure of the padding yarn is a deformation of 0-0 / 1-1 / / .

[0033] Or the yarn Y3 is woven to form at least one dense area, which covers the mesh structure area formed by the yarn Y1, and the digital structure of the padding yarn is a deformation of 1-0 / 1-2 / / .

[0034] The yarn Y1 and the yarn Y2 are both elastic composite yarns, and the linear density of the elastic composite yarn is 20-280D. The elastic composite yarn is a mixture of filament yarn and spandex yarn, wherein the linear density of the filament yarn is 10-140D, and the linear density of the spandex yarn is 10-100D.

[0035] The Y3 is a filament with a linear density of 20-280D. Alternatively, the Y3 is an elastic composite yarn composed of a filament and a spandex yarn with a linear density of 20-280D, wherein the filament linear density is 10-140D and the spandex linear density is 10-70D.

[0036] The fabric body is woven by a warp knitting machine, and the needle density of the warp knitting machine is 14-32 per inch.

[0037] The pattern layer is the surface layer of the fabric body. By setting a dense structure area and a mesh structure area, the mesh structure area is made of elastic yarn. When it is in a free state, that is, not stretched, the mesh structure area on the pattern layer on the fabric body shrinks and becomes dense, which is basically consistent with the dense structure area on the pattern layer. When the fabric body is stretched, the entire fabric body is expanded in the stretching direction, and the elastic mesh structure area is also stretched, thereby revealing the original mesh shape, and with the change of the stretching force, a dynamic pattern appearance is formed. This adds to the mystery of the fabric, enhances the artistry of the fabric, and enriches the diversity of the fabric. It can be widely used in underwear, sports and other clothing fields.

[0038] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
