Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, in particular to a composite interwoven double-sided fabric. Background Art

[0002] Traditional knitted fabrics are made by bending yarns into loops and then interlacing them. The loops have a large room for expansion and contraction up and down, left and right, and have good elasticity. They fit the body when worn, are comfortable and convenient, and are suitable for stretching and bending during human exercise. Because the loops that make up the knitted fabrics are interlaced, countless isolated air pockets are formed inside the fabric, which has good warmth retention and breathability, and good moisture absorption performance. Moreover, when the knitted fabric is subjected to external forces of wrinkles, the loops can be transferred to adapt to the deformation under the force; when the wrinkle force disappears, the transferred yarn can be quickly restored to its original state. It is comfortable to wear, fits the body, and can fully reflect the curves of the human body. However, knitted fabrics are easy to fall apart, curl, and snag, and are not as strong and durable as woven fabrics. Woven fabrics are made with rapier machines, and the facade is more beautiful. The use of woven fabrics in clothing is in a world-leading position in terms of variety and production quantity.

[0003] Therefore, how to combine the characteristics of knitted fabrics and woven fabrics to produce a high-performance fabric that has both the various superior properties of knitted fabrics and the three-dimensional appearance and crispness of woven fabrics, and has a double-sided appearance, is a technical problem that needs to be urgently solved by people in this field. Summary of the invention

[0004] The object of the present invention is to provide a composite interwoven double-sided fabric, aiming to solve the problem that the existing fabric cannot have the superior properties of knitted fabrics and woven fabrics at the same time.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] Provided is a composite interwoven double-sided fabric, comprising a front layer, a back layer and a plurality of intermediate layers, wherein the longitudinal direction of the composite interwoven double-sided fabric is composed of warp yarns of m dimensions, and the transverse direction of the composite interwoven double-sided fabric is composed of weft yarns of n dimensions, wherein m≥2, n≥2;

[0007] The front layer is composed of warp yarns of the first dimension interwoven with weft yarns of the first dimension, at least one intermediate layer is composed of warp yarns of the second dimension interwoven with weft yarns of the first dimension, and the back layer is composed of warp yarns of the mth dimension interwoven with weft yarns of the nth dimension.

[0008] Optionally, the arrangement ratio of the number of warp yarns in the first dimension to the number of warp yarns in the second dimension is 1:1.

[0009] Optionally, the warp yarns in the first dimension are non-elastic yarns and the warp yarns in the second dimension are elastic yarns.

[0010] Optionally, the warp yarn of the first dimension is a yarn spun from short fibers, and the yarn count range is 4S to 80S.

[0011] Optionally, the warp yarn of the second dimension is a yarn spun from filaments, and the yarn fineness ranges from 20D to 600D.

[0012] Optionally, the arrangement ratio of the number of weft yarns in the first dimension to the number of weft yarns in the second dimension is 1:1.

[0013] Optionally, the weft yarns in the first dimension are elastic yarns and the weft yarns in the second dimension are non-elastic yarns.

[0014] Optionally, the weft yarn of the first dimension is a yarn spun from short fibers, and the yarn count range is 6S to 80S.

[0015] Optionally, the thickness of the warp yarns in the first dimension is thicker than or equal to the thickness of the warp yarns in the second dimension, the number of interlacing points of the warp yarns in the second dimension and the weft yarns in the first dimension is more than or equal to the number of interlacing points of the warp yarns in the first dimension and the weft yarns in the first dimension, and the tightness of interlacing of the warp yarns in the second dimension and the weft yarns in the first dimension is greater than the tightness of interlacing of the warp yarns in the first dimension and the weft yarns in the first dimension.

[0016] Optionally, the weave structure of the warp yarns of the second dimension interlaced with the weft yarns of the first dimension is a 1 / 1 plain weave.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the composite interwoven double-sided fabric provided by the present invention, the warp direction of the fabric can simulate various properties of warp knitted fabrics, and the weft direction can simulate various properties of weft knitted fabrics, thereby replacing the traditional warp and weft knitted fabrics. At the same time, the characteristics of the two knitted fabrics are cleverly combined to form a double-layer double-elastic woven fabric, which also has the three-dimensional texture appearance of the woven fabric.

[0019] Among them, the front and back layers of the fabric are connected by a middle layer, and the middle layer is connected by a 1 / 1 plain weave. The fabric is alternately loose and tight, forming a longitudinal and transverse air convection layer inside the fabric, which is more airy than the previous air layer fabric in one direction.

[0020] In addition, the fabric has a three-dimensional and full texture on both sides, a soft and skin-friendly feel, and a crisp texture, which makes the fabric not easy to loosen and slip, and the fabric is not easy to deform. Compared with ordinary double-layer fabrics, this kind of tissue structure design has a clearer texture, is fluffy, breathable, and locks in warmth. The fabric can form air elasticity on all sides, giving consumers a composite functional experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0032] Combine the following Figures 1 to 7 The composite interwoven double-faced fabric of the present invention is described.

[0033] like Figures 1 to 7 As shown, the present invention provides a composite interwoven double-sided fabric, which includes a front layer, a back layer and a plurality of middle layers. The longitudinal direction of the composite interwoven double-sided fabric is composed of warp yarns of m dimensions, and the transverse direction of the composite interwoven double-sided fabric is composed of weft yarns of n dimensions, wherein m≥2, n≥2; the front layer is composed of warp yarns of a first dimension interwoven with weft yarns of a first dimension, at least one middle layer is composed of warp yarns of a second dimension interwoven with weft yarns of a first dimension, and the back layer is composed of warp yarns of an mth dimension interwoven with weft yarns of an nth dimension.

[0034] In this embodiment, dimension refers to the spatial dimension in the horizontal and vertical directions. There are many warp yarns of the same dimension. The warp yarns of the same dimension can be understood as the same group of warp yarns. Warp yarns of two different dimensions refer to two groups of warp yarns arranged in the same direction, and the same is true for weft yarns.

[0035] In this embodiment, if Figure 1 As shown, m=2, n=2, that is, the longitudinal direction of the composite interwoven double-sided fabric is composed of warp yarns of two dimensions, the transverse direction of the composite interwoven double-sided fabric is composed of weft yarns of two dimensions, and the middle layer has only one layer, which is composed of the warp yarns of the second dimension and the weft yarns of the first dimension interwoven.

[0036] It is understandable that in some other embodiments, the values ​​of m and n may be changed according to actual conditions, for example:

[0037] 1. If m>n, the number of intermediate layers is |mn|*2, such as Figure 2 As shown, for example, when the longitudinal direction is composed of three-dimensional warp yarns and the transverse direction is composed of two-dimensional weft yarns, and they are interwoven with each other in the longitudinal and transverse directions, the warp yarns of the first dimension are interwoven with the weft yarns of the first dimension to form the first layer structure of the fabric, forming the front effect of the fabric; the warp yarns of the second dimension are interwoven with the weft yarns of the first dimension and the weft yarns of the second dimension respectively to form the second and third layer structures of the fabric, forming the middle layer structure of the fabric; the warp yarns of the third dimension are interwoven with the weft yarns of the second dimension to form the fourth layer structure of the fabric, forming the back effect of the fabric, and the middle layer of the fabric has two layers.

[0038] 2. If m<n, the number of intermediate layers is |mn|*2, such as Figure 3 As shown, for example, when the longitudinal direction is composed of two-dimensional warp yarns and the transverse direction is composed of three-dimensional weft yarns, and they are interwoven with each other in the longitudinal and transverse directions, the warp yarns of the first dimension are interwoven with the weft yarns of the first dimension to form the first layer structure of the fabric, forming the front effect of the fabric; the warp yarns of the second dimension are interwoven with the weft yarns of the first dimension and the weft yarns of the second dimension respectively to form the second and third layer structures of the fabric, forming the middle layer structure of the fabric; the warp yarns of the second dimension are interwoven with the weft yarns of the third dimension to form the fourth layer structure of the fabric, forming the back effect of the fabric, and the middle layer of the fabric has two layers.

[0039] 3. If m=n, and m>2, the total number of layers is 2m-1, such as Figure 4 As shown, the number of middle layers is 2m-3. For example, when the longitudinal direction is composed of three-dimensional warp yarns and the transverse direction is composed of three-dimensional weft yarns, and they are interwoven with each other in the longitudinal and transverse directions, the warp yarns of the first dimension are interwoven with the weft yarns of the first dimension to form the first layer structure of the fabric, forming the front effect of the fabric; the warp yarns of the second dimension are interwoven with the weft yarns of the first dimension and the weft yarns of the second dimension respectively to form the second and third layer structures of the fabric, the warp yarns of the third dimension are interwoven with the weft yarns of the second dimension to form the fourth layer structure of the fabric, and the second, third and fourth layer structures form the middle layer structure of the fabric; the warp yarns of the third dimension are interwoven with the weft yarns of the third dimension to form the fifth layer structure of the fabric, forming the back effect of the fabric, and the middle layer of the fabric has 3 layers.

[0040] In some embodiments, the weave structure in which the warp yarns of the first dimension and the weft yarns of the first dimension are interwoven is preferably a 3 / 1 twill, a commonly used woven pattern. In some other embodiments, the weave structure in which the warp yarns of the first dimension and the weft yarns of the first dimension are interwoven may also be a common fabric pattern such as plain weave, twill, satin, or alternating weave.

[0041] In some embodiments, the weave structure in which the warp yarns of the second dimension are interwoven with the weft yarns of the first dimension has 1-4 continuous warp weave points, preferably 1-2, so that the fabric will be tightly connected, with a crisp texture and three-dimensional lines.

[0042] In some embodiments, the weaving structure of the warp yarns of the second dimension and the weft yarns of the first dimension is 1 / 1 plain weave. Since the warp yarns of the first dimension are thicker than the warp yarns of the second dimension, the front style of the fabric, that is, the interweaving of the warp yarns of the first dimension and the weft yarns of the first dimension is driven by the interweaving of the warp yarns of the second dimension and the weft yarns of the first dimension. Due to the dense 1 / 1 plain weave interweaving points of the warp yarns of the second dimension and the weft yarns of the first dimension, the texture will become more three-dimensional and the grooves will be deeper.

[0043] In some embodiments, the arrangement ratio of the number of warp yarns in the first dimension to the number of warp yarns in the second dimension is 1:1. In some other embodiments, the arrangement ratio of the number of warp yarns in the first dimension to the number of warp yarns in the second dimension can be 3:1, 2:1, 3:2, 2:3, 1:2, 1:3, etc.

[0044] In some embodiments, the warp yarns in the first dimension are inelastic yarns, and the warp yarns in the second dimension are elastic yarns. The warp yarns in the first dimension form the front style layer of the fabric, and the warp yarns in the second dimension drive the warp yarns in the first dimension to drive the longitudinal movement, simulating the warp coil snare effect of the warp knitted fabric. The warp yarns in the first dimension form a woven three-dimensional texture, and the warp yarns in the second dimension form the elastic effect of the warp knitted fabric.

[0045] In some other embodiments, the warp yarns in the first dimension and the warp yarns in the second dimension may both be elastic yarns or non-elastic yarns, and may be the same yarns or different yarns.

[0046] In some embodiments, the warp yarn of the first dimension is yarn spun from short fibers, and the yarn count range is 4S to 80S, so that the front side of the fabric can form a three-dimensional woven fabric texture.

[0047] In some other embodiments, the warp yarn of the first dimension may also be a yarn spun from filaments, and the yarn fineness ranges from 50D to 1000D.

[0048] In some embodiments, the warp yarn of the second dimension is a yarn spun from filaments, and the yarn fineness ranges from 20D to 600D. Since the warp yarn of the second dimension is located in the middle layer of the fabric, considering the cost of the fabric, yarn spun from filaments is preferred.

[0049] In some other embodiments, the warp yarn of the second dimension may also be yarn spun from short fibers, with a yarn count ranging from 10S to 80S.

[0050] In some embodiments, the warp yarns of the first dimension form the front style of the fabric, and the preferred raw materials are cotton fibers among natural fibers, viscose fibers, lyocell fibers, modal fibers, etc. among regenerated fibers.

[0051] In some embodiments, the warp yarns in the second dimension drive the movement of the warp yarns in the first dimension, and the interlaced layer is located in the middle layer of the fabric. Due to cost, it is preferably thinner than the warp yarns in the first dimension. The preferred raw materials are polyester fibers, polyamide fibers, etc. among chemical fibers.

[0052] In some embodiments, the arrangement ratio of the number of weft yarns in the first dimension to the number of weft yarns in the second dimension is 1:1. In some other embodiments, the arrangement ratio of the number of weft yarns in the first dimension to the number of weft yarns in the second dimension can be 3:1, 2:1, 3:2, 2:3, 1:2, 1:3, etc.

[0053] In some embodiments, the weft yarn of the first dimension is an elastic yarn, and the weft yarn of the second dimension is an inelastic yarn. The warp yarn of the first dimension and the weft yarn of the first dimension are interwoven to form a front style layer of the fabric. The weft yarn of the first dimension drives the weft yarn of the second dimension to drive the lateral stretching movement of the fabric. Since the interweaving points of the weft yarn and the warp yarn of the first dimension are generally denser than the interweaving points of the weft yarn and the warp yarn of the second dimension, it is preferred that the weft yarn of the second dimension has more continuous weft tissue points than the weft yarn of the first dimension. Then, the weft yarn of the second dimension will form annular rings, making the fabric fluffy and light, simulating the weft coil loop effect of a weft-knitted fabric. The weft yarn of the first dimension forms a woven three-dimensional texture, and the weft yarn of the second dimension forms the elastic effect and annular coil effect of a warp-knitted fabric.

[0054] In some other embodiments, the weft yarns in the first dimension and the weft yarns in the second dimension may both be elastic yarns or non-elastic yarns, and may be the same yarns or different yarns.

[0055] In some embodiments, the weft yarn of the first dimension is a yarn spun from short fibers, and the yarn count range is 6S to 80S, so that the front side of the fabric can form a three-dimensional woven fabric texture.

[0056] In some other embodiments, the weft yarn of the first dimension may also be a yarn spun from filaments, and the yarn fineness ranges from 20D to 600D.

[0057] In some embodiments, the second dimension weft yarn can be a yarn spun from short fibers, with a yarn count range of 10S to 80S, or a yarn spun from filaments, with a yarn fineness range of 20D to 600D. Since the styles of the reverse side vary, the yarn spun from short fibers and the yarn spun from filaments can be selected at will according to the style changes.

[0058] In some embodiments, the thickness of the warp yarns in the first dimension is thicker than or equal to the thickness of the warp yarns in the second dimension, the number of interlacing points between the warp yarns in the second dimension and the weft yarns in the first dimension is more than or equal to the number of interlacing points between the warp yarns in the first dimension and the weft yarns in the first dimension, and the tightness of interlacing between the warp yarns in the second dimension and the weft yarns in the first dimension is greater than the tightness of interlacing between the warp yarns in the first dimension and the weft yarns in the first dimension.

[0059] In some embodiments, the front layer and the middle layer of the fabric are interwoven by warp yarns in two longitudinal dimensions and weft yarns in the first dimension. First, the warp yarns in the first dimension are interwoven with the weft yarns in the first dimension to form the front appearance, and the warp yarns in the second dimension and the weft yarns in the first dimension constitute the middle layer. In order to make the fabric form a three-dimensional texture of a woven fabric, when the warp yarns in the second dimension are interwoven with the weft yarns in the first dimension, it is necessary to basically not affect the front texture of the fabric. Preferably, the thickness of the warp yarns in the first dimension is coarser than that of the warp yarns in the second dimension, and preferably, the interweaving points of the warp yarns in the second dimension and the weft yarns in the first dimension are more than the interweaving points of the warp yarns in the first dimension and the weft yarns in the first dimension, and preferably, the tightness of the interweaving of the warp yarns in the second dimension and the weft yarns in the first dimension is greater than the tightness of the interweaving of the warp yarns in the first dimension and the weft yarns in the first dimension.

[0060] In some embodiments, the weaving structure of the warp yarns in the second dimension and the weft yarns in the first dimension is 1 / 1 plain weave, and the weaving structure of the warp yarns in the second dimension and the weft yarns in the first dimension constitute the middle layer of the fabric. Because its density must be denser or as dense as the front layer to highlight the front texture of the fabric, the weaving structure can be 1 / 1 plain weave, 2 / 1 twill, square weave, etc., preferably 1 / 1 plain weave.

[0061] In some embodiments, the weft yarn of the first dimension forms the front style of the fabric, and the preferred raw materials are cotton fibers among natural fibers, viscose fibers, lyocell fibers, modal fibers, etc. among regenerated fibers, polyester fibers, polyamide fibers, etc. among chemical fibers, and polyester fibers, polyamide fibers, etc. among chemical fibers.

[0062] In some embodiments, the second dimension of the weft yarn forms the reverse side of the fabric and fits the skin, and needs to have a better feel. The preferred raw materials are cotton fibers among natural fibers, viscose fibers, lyocell fibers, modal fibers, etc. among regenerated fibers, ultra-fine denier polyester fibers, ultra-fine denier polyamide fibers among chemical fibers, and chenille fibers among fancy yarns. If the wool is sheared or sanded, polyester fibers and polyamide fibers among chemical fibers may be preferred.

[0063] In some embodiments, the weave structure of the second dimension warp yarn and the second dimension weft yarn can be changed at will, that is, various weave structures of warp and weft knitted fabrics can be simulated, such as warp plain weave, plating weave, padding weave, corrugated weave, terry weave, plush weave, etc., to form the reverse layer of the fabric. The imitation of the warp plain weave can be designed as a woven double plain weave, the imitation of the plating weave and padding weave can be designed as a wicker weave, the imitation of the corrugated weave can be designed as a herringbone weave, the imitation of the terry weave and plush weave can be designed as a weft floating long line weave, etc., so that the reverse weave of the fabric is diversified.

[0064] In the composite interwoven double-sided fabric provided by the present invention, the warp direction of the fabric can simulate various properties of warp knitted fabrics, and the weft direction can simulate various properties of weft knitted fabrics, thereby replacing the traditional warp and weft knitted fabrics. At the same time, the characteristics of the two knitted fabrics are cleverly combined to form a double-layer double-elastic woven fabric, which also has the three-dimensional texture appearance of the woven fabric.

[0065] Among them, the front and back layers of the fabric are connected by a middle layer, and the middle layer is connected by a 1 / 1 plain weave. The fabric is alternately loose and tight, forming a longitudinal and transverse air convection layer inside the fabric, which is more airy than the previous air layer fabric in one direction.

[0066] In addition, the fabric has a three-dimensional and full texture on both sides, a soft and skin-friendly feel, and a crisp texture, which makes the fabric not easy to loosen and slip, and the fabric is not easy to deform. Compared with ordinary double-layer fabrics, this kind of tissue structure design has a clearer texture, is fluffy, breathable, and locks in warmth. The fabric can form air elasticity on all sides, giving consumers a composite functional experience.
