Description

A multi-comb jacquard three-dimensional jacquard mesh and its preparation method Technical Field

[0001] The present application relates to the technical field of warp knitted mesh fabrics, and in particular to a multi-comb jacquard three-dimensional jacquard mesh fabric and a preparation method thereof. Background Art

[0002] Sandwich mesh is a double-needle-bar warp-knitted fabric consisting of a mesh surface, connected monofilaments, and a plain base. Its three-dimensional structure, resembling a Western sandwich, evokes its name. Typically, the mesh's pattern is jacquard, offering a variety of patterns. However, due to its jacquard bar construction, the mesh's high thread density and thick texture result in poor breathability and a lack of layering. Its performance and aesthetics still require further improvement.

[0003] In addition, most of the sandwich mesh fabrics on the market are mainly flat, single-color or two-color fabric pattern designs, and are woven using the conventional three-needle looping principle of warp knitting jacquard. The specific disadvantages are: they are mainly flat, and the product characteristics can only be reflected through changes in the fabric mesh size, mesh shape, and thickness structure, and lack a three-dimensional appearance.

[0004] Summary of the Invention

[0005] Other features and advantages of the present application will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present application. The purpose and other advantages of the present application can be realized and obtained through the structures specifically pointed out in the description and other drawings.

[0006] The purpose of this application is to overcome the above-mentioned shortcomings and provide a multi-comb jacquard three-dimensional jacquard mesh and its preparation method. This application utilizes the high shrinkage of high-elastic yarn and the low shrinkage of low-elastic yarn, and uses two different jacquard combs to pad yarn and use the jacquard basic structure to weave a three-dimensional jacquard pattern, greatly enhancing the three-dimensional effect of the mesh, making the mesh more delicate and thick, and having strong structural stability.

[0007] In the first aspect, the present application provides a multi-comb jacquard three-dimensional jacquard mesh, comprising a mesh body woven integrally by a warp knitting machine, the mesh body comprising a surface layer, a bottom layer woven under the surface layer, and a connecting layer woven between the surface layer and the bottom layer, the surface layer being woven with a first warp knitting basic structure, the bottom layer being woven with a second warp knitting basic structure, and the connecting layer being used to connect the surface layer and the bottom layer; wherein, the surface layer or / and the bottom layer are woven with a three-dimensional jacquard pattern, the three-dimensional jacquard pattern comprising a jacquard outline and a jacquard protrusion, the jacquard outline being woven by a jacquard comb through a second jacquard basic structure, the jacquard protrusion being woven by a jacquard comb through a first jacquard basic structure, the jacquard protrusion on the jacquard mesh being a first area, and the rest being a second area, the thickness of the first area being greater than the thickness of the second area, the jacquard or / and mesh being woven in the first area, and the jacquard or / and mesh being woven in the second area.

[0008] This application utilizes two different jacquard combs to pad yarn and uses the jacquard basic structure, and combines colored yarn with functional yarn to weave a three-dimensional jacquard pattern, which greatly enhances the three-dimensional effect of the mesh and makes the mesh more delicate and thick, with strong structural stability.

This application utilizes the high shrinkage of high-elastic yarn and the low shrinkage of low-elastic yarn to weave the jacquard protrusions with the low-elastic yarn and the jacquard outline with the high-elastic yarn. Due to the high shrinkage of the high-elastic yarn, the jacquard outline shrinks, squeezing the jacquard protrusions outward, giving the jacquard protrusions a stronger three-dimensional sense of relief, thereby enhancing the three-dimensional effect of the mesh.

This application leverages the high shrinkage of high-elastic yarn and the low shrinkage of low-elastic yarn, weaving the jacquard projections with low-elastic yarn and the jacquard outline with high-elastic yarn. Due to the high shrinkage of the high-elastic yarn, the jacquard outline shrinks, squeezing the jacquard projections outward, giving the jacquard projections a stronger three-dimensional sense of relief, thereby enhancing the three-dimensional effect of the mesh. Furthermore, a plurality of meshes are woven within the jacquard projections, significantly improving the mesh's breathability.

[0018] In some embodiments, the thickness of the raised area changes in a direction from the inside to the outside or from the outside to the inside, and the thickness changes in the horizontal direction and / or the vertical direction.

[0019] In some embodiments, the shoe upper is made of a multi-comb jacquard three-dimensional jacquard mesh, and yarn with elastic properties is woven into at least one position of the shoe side, shoe opening, and shoe heel of the shoe upper.

[0020] In some embodiments, the upper is made of a multi-comb jacquard three-dimensional jacquard mesh fabric, and the elastic area and the non-elastic area of ​​the upper are customized by selecting yarns and / or basic tissue structures.

[0021] In some embodiments, the shoe upper is made of a multi-comb jacquard three-dimensional jacquard mesh fabric, and the jacquard protrusions on the shoe upper form a supporting skeleton, which is woven from yarns that do not have elastic properties.

[0022] In the second aspect, the present application provides a method for preparing a multi-comb jacquard three-dimensional jacquard mesh, which includes using a double-needle bed jacquard warp knitting machine to weave the mesh, wherein the mesh includes a surface layer, a bottom layer woven under the surface layer, and a connecting layer woven between the surface layer and the bottom layer.

[0043] The following will describe in detail the implementation methods of this application in conjunction with the accompanying drawings and examples, so that the application can fully understand how technical means are used to solve technical problems and achieve technical effects, and implement them accordingly. It should be noted that as long as there is no conflict, the various embodiments and the various features in each embodiment of this application can be combined with each other, and the resulting technical solutions are all within the scope of protection of this application.

[0044] While many specific details are set forth in the following description for purposes of explanation, in order to provide a thorough understanding of the embodiments of the present application, it will be apparent to those skilled in the art that the present application may be implemented without the specific details herein or the particular manner described.

[0045] According to some embodiments of the present application, with reference to Figures 1 to 5, the present application provides a multi-comb jacquard three-dimensional jacquard mesh, comprising a mesh body woven integrally by a warp knitting machine, the mesh body comprising a surface layer 1, a bottom layer 2 woven under the surface layer 1, and a connecting layer 3 woven between the surface layer 1 and the bottom layer 2, the surface layer 1 being woven with a first warp knitting basic structure, the bottom layer 2 being woven with a second warp knitting basic structure, and the connecting layer 3 being used to connect the surface layer 1 and the bottom layer 2; wherein, the surface layer 1 or / and the bottom layer 2 are woven with a three-dimensional jacquard pattern 4, the three-dimensional jacquard pattern 4 comprising a jacquard outline 41 and a jacquard protrusion 42, the jacquard outline 41 being woven by a jacquard comb through the second jacquard basic structure, the jacquard protrusion 42 being woven by a jacquard comb through the first jacquard basic structure, the jacquard protrusion 42 on the jacquard mesh being a first area, and the rest being a second area, the thickness of the first area being greater than the thickness of the second area, jacquard or / and mesh 421 being woven in the first area, and jacquard or / and mesh 421 being woven in the second area.

[0046] This application utilizes two different jacquard combs to pad yarns and uses the basic jacquard structure, and combines colored yarns with functional yarns to weave a three-dimensional jacquard pattern 4, which greatly enhances the three-dimensional effect of the mesh and makes the mesh more delicate and thick, with strong structural stability.

[0047] According to some embodiments of the present application, the surface layer 1 is optionally woven with a three-dimensional jacquard pattern 4, comprising a jacquard outline 41 and jacquard protrusions 42. The jacquard outline 41 is woven by a jacquard bar using a first jacquard basic weave, and the jacquard protrusions 42 are woven by a jacquard bar using a second jacquard basic weave. By weaving the three-dimensional jacquard pattern 4 having the jacquard protrusions 42 and the jacquard outline 41 on the surface layer 1, the present application greatly enhances the visual sense of the three-dimensional effect of the mesh surface and greatly improves its aesthetics.

[0048] According to some embodiments of the present application, the base layer 2 is optionally woven with a three-dimensional jacquard pattern 4, comprising a jacquard outline 41 and jacquard protrusions 42. The jacquard outline 41 is woven by a jacquard bar using a first jacquard basic weave, and the jacquard protrusions 42 are woven by a jacquard bar using a second jacquard basic weave. By weaving a three-dimensional jacquard pattern 4 having jacquard protrusions 42 and a jacquard outline 41 on the base layer 2, the present application provides the inner surface of the mesh with three-dimensional protrusions. When the mesh contacts the skin, it can provide a massage effect. Moreover, the inner surface of the mesh only partially contacts the skin, which can prevent friction or adhesion that would otherwise occur if the mesh and skin were in full contact.

[0049] According to some embodiments of the present application, the surface layer 1 and the bottom layer 2 are optionally woven with a three-dimensional jacquard pattern 4. The three-dimensional jacquard pattern 4 includes a jacquard outline 41 and a jacquard protrusion 42. The jacquard outline 41 is woven by a jacquard bar using a first jacquard basic weave, and the jacquard protrusion 42 is woven by a jacquard bar using a second jacquard basic weave. By weaving the three-dimensional jacquard pattern 4 on the surface of the surface layer 1 and the bottom layer 2, the present application achieves a concave-convex texture on both sides of the mesh, thereby realizing multiple functions.

[0050] According to some embodiments of the present application, the jacquard profile 41 may optionally be made of a high-elastic yarn, while the jacquard protrusions 42 may be made of a low-elastic yarn. This application utilizes the high shrinkage of the high-elastic yarn and the low shrinkage of the low-elastic yarn to weave the jacquard protrusions 42 with the low-elastic yarn and the jacquard profile 41 with the high-elastic yarn. Due to the high shrinkage of the high-elastic yarn, the jacquard profile 41 contracts while squeezing the jacquard protrusions 42 outward, giving the jacquard protrusions 42 a stronger three-dimensional raised feel, thereby enhancing the three-dimensional effect of the mesh.

[0051] Both high-stretch yarn and low-stretch yarn are considered stretch yarns. Stretch yarn is a type of bulked yarn, made from filament or staple yarns with high elastic elongation and rapid recovery. It can be categorized as high-stretch yarn or low-stretch yarn based on its elastic elongation. High-stretch yarn has an elastic elongation of approximately 30%-50%. Examples include textured filament yarns made from thermoplastic filaments through heat setting and false twisting or knife-edge curling, filament yarns made from spandex elastic filaments composited with other filaments, spandex core-spun yarns or spandex-covered yarns used in the warp knitting industry, and physically elastic yarns with modified spring appearance properties. Low-stretch yarn has an elastic elongation of approximately 10%-30%. Examples include filament yarns made from high-stretch yarns subjected to a second heat setting treatment, core-spun yarns made with spandex elastic filaments as the core yarn, and blended staple yarns with elastic fibers.

[0052] According to some embodiments of the present application, optionally, meshes 421 are woven into the jacquard protrusions 42. The present application weaves a plurality of meshes 421 into the jacquard protrusions 42, which greatly improves the air permeability of the mesh.

[0053] According to some embodiments of the present application, a mesh 421 is optionally woven within the jacquard protrusions 42, with the jacquard outline 41 made of a high-elastic yarn and the jacquard protrusions 42 made of a low-elastic yarn. This application utilizes the high shrinkage of high-elastic yarn and the low shrinkage of low-elastic yarn to weave the jacquard protrusions 42 with the low-elastic yarn and the jacquard outline 41 with the high-elastic yarn. Due to the high shrinkage of the high-elastic yarn, the jacquard outline 41 contracts, squeezing the jacquard protrusions 42 outward, creating a stronger three-dimensional raised feel for the jacquard protrusions 42 and enhancing the three-dimensional effect of the mesh. Furthermore, a plurality of meshes 421 are woven within the jacquard protrusions 42, significantly improving the mesh's breathability.

[0054] According to some embodiments of the present application, optionally, the bottom layer 2 is woven with ventilation holes 21. The present application has a plurality of ventilation holes 21 woven into the bottom layer 2, which greatly enhances the breathability of the mesh.
