Description

Technical Field

[0001] The invention relates to the field of textile fabrics, in particular to a lightweight, thick-knitted raised fabric. Background Art

[0002] Knitted fabrics are widely used in the textile industry, particularly in clothing, where they are favored by consumers for their excellent stretchability and comfort. In recent years, to meet market demand for lightweight and warm fabrics, researchers have been committed to developing new fabrics to enhance comfort and functionality. In particular, in the development of winter clothing, achieving both lightweight and warm fabrics has become a key research focus.

[0003] Currently, to address the issue of insufficient warmth in lightweight fabrics, traditional techniques typically involve increasing fabric thickness or adding a thermal layer. Another approach involves improving the fabric's structure, such as enhancing its loftiness through structural design changes to achieve a warming effect. Specialized yarns or fibers, such as hollow fibers or other materials with high thermal insulation properties, are also being used to enhance the fabric's warmth. Furthermore, there are technologies that control the connection between yarns during the knitting process, improving the warmth and comfort of the fabric by altering the weave.

[0004] However, these methods have limitations in practice. In particular, increasing fabric thickness can make it too bulky, affecting the wearer's experience. While improvements in fabric structure and the use of specialized fiber materials can improve warmth to a certain extent, achieving both lightness and warmth remains challenging. Maintaining both lightness and warmth remains a significant challenge. Summary of the Invention

[0005] In order to improve the warmth retention of lightweight fabrics, the present application provides a lightweight, thick knitted raised fabric.

[0006] The present application provides a lightweight thick knitted raised fabric using the following technical solutions:

[0007] A lightweight, thick knitted raised fabric comprises a surface layer and an inner layer, both of which are multi-layer structures; the surface layer and the inner layer are connected by a connecting layer, and the side of the surface layer and the inner layer that are away from each other is a single coil structure, in which an incompletely withdrawn coil arc is provided in the single coil structure, and the coil arc is woven into a loop simultaneously with the single coil.

[0008] By adopting the above technical solution, the double-sided knitted fabric has a multi-layer structure, with two or more layers on the front and back sides respectively. The front and back sides of the fabric are fixed and connected together by the middle layer. The multi-layer fabric structure formed makes the overall structure more stable, which helps to improve the warmth retention performance of the fabric. At the same time, the size of the coils on the front and back sides of the fabric can be adjusted as needed, thereby improving the adaptability and design flexibility of the fabric.

[0009] Preferably, there are n rows of stitches, and the n rows of stitches are woven from at least n+1 yarns, where n≥2; the rows of stitches are formed by two or more layers of the same or different yarns, and at least part of the stitches in one row of stitches among the stitches formed by the surface layer and the inner layer contain one or more incompletely unstuck stitches, and the stitches are dispersed in the rows of the surface layer and the inner layer.

[0010] By adopting the above technical solution, both the surface layer and the inner layer are provided with rows of coils with incomplete unwinding. The rows of coils are woven into loops by two or more layers of the same or different yarns at the same time, forming overlapping coils of two or more layers of yarn, and the rows of coils are dispersed in the horizontal rows of the surface layer and the inner layer, connected by the coil hanging arcs, and the coil hanging arcs are not completely unwound, thereby improving the thickness and warmth retention of the fabric, while maintaining good elasticity, improving the fluffiness and softness of the fabric, and enhancing wearing comfort.

[0011] Preferably, the coil row is provided with a coil portion and a hanging loop portion, and the coil portion and the hanging loop portion of the same coil row are woven from long fibers or short fibers, wherein the long fibers and short fibers are of any composition type.

[0012] By adopting the above technical solution, the coil rows are provided with coil parts and hanging arc parts, and are woven from long fibers and short fibers, so that the fabric maintains its lightweight while enhancing the stability and durability of the structure, further improving the comfort and warmth retention of the fabric.

[0013] Preferably, the yarn of the connecting layer is connected to the surface layer and the inner layer in an incompletely unhooked manner, the yarn of the connecting layer is connected to the loops in the same horizontal row of the surface layer or the inner layer, and the yarn of the connecting layer forms a suspended arc on the same knitting needles of the surface layer and the inner layer.

[0014] By adopting the above technical solution, the yarn of the connecting layer is connected to the surface layer and the inner layer in an incompletely unhooked manner, and the yarn of the connecting layer is connected to the loops in the same horizontal row of the surface layer or the inner layer, thereby enhancing the connection strength between the surface layer and the inner layer, while ensuring the overall stability and softness of the fabric.

[0015] Preferably, the yarn thickness of the surface layer is smaller than that of the yarn of the inner layer; and the transverse density of the surface layer coils is greater than that of the inner layer coils.

[0016] By adopting the above technical solution, the yarn thickness on the front side of the fabric can be less than or equal to the yarn thickness on the back side, and the lateral density of the front coil is greater than the lateral density of the back coil, so that the front side of the fabric has a higher tightness and a more delicate feel, while the back side is relatively soft, thereby enhancing the comfort and aesthetics of the fabric.

[0017] Preferably, the surface layer is woven from one or more of hollow fibers and special-shaped fibers, the connecting layer is woven from one of hollow fibers and special-shaped fibers, and the inner layer is woven from one or more of fully drawn fibers and semi-drawn fibers.

[0018] By adopting the above technical solution, the surface layer is woven with hollow fibers and special-shaped fibers, the connecting layer is also woven with hollow fibers and special-shaped fibers, and the inner layer is woven with fully-drawn fibers and semi-drawn fibers. This allows the fabric to maintain good fluffiness while improving overall warmth and comfort.

[0019] Preferably, the yarn thickness of the connecting layer is in the range of 20-60 deniers, and the yarn thickness of the surface layer and the inner layer is in the range of 30-150 deniers.

[0020] By adopting the above technical solution, the yarn thickness of the connecting layer is controlled within the range of 20-60 denier, so that the connecting layer has better strength and softness, thereby improving the overall stability and comfort of the fabric.

[0021] Preferably, the surface layer is woven into a pattern by a reasonable combination of looping, tucking and floating lines.

[0022] By adopting the above technical solution, through the reasonable combination of loop forming, tucking and floating lines, a patterned structure can be woven on the surface of the fabric, thereby improving the aesthetics and functionality of the fabric.

[0023] In summary, this application has the following beneficial technical effects:

[0024] 1. Double-faced knitted fabrics have a multi-layer structure, with two or more layers on each side. The front and back of the fabric are fixed and connected by a middle layer. The multi-layered fabric structure makes the overall structure more stable, which helps to improve the warmth retention of the fabric. At the same time, the size of the loops on the front and back of the fabric can be adjusted as needed, which improves the adaptability and design flexibility of the fabric.

[0025] 2. Both the surface and lining layers are provided with incompletely unwound courses. These courses are knitted simultaneously with two or more layers of the same or different yarns, resulting in overlapping loops of two or more layers of yarn. These courses are dispersed throughout the rows of the surface and lining layers, thereby increasing the fabric's thickness and warmth while maintaining good elasticity.

[0026] 3. The yarn thickness on the front side of the fabric can be made equal to or less than that on the back side, and the lateral density of the front loops is greater than that of the back loops. This gives the front side of the fabric a tighter and more delicate feel, while the back side is relatively soft, enhancing the fabric's comfort and aesthetics. In particular, when the lateral density of the front loops is 1.5-2.5 times that of the back loops, the fabric's layering and functionality are further enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application is further described in detail below with reference to the following examples and comparative examples. Example

[0031] The embodiment of the present application discloses a lightweight thick knitted fleece fabric, such as Figure 1 As shown: The knitted raised fabric comprises a surface layer 1, a connecting layer 3, and an inner layer 2. The surface layer 1 is woven from hollow fibers and shaped fibers, while the inner layer 2 is woven from fully drawn fibers and pure cotton fibers. By combining these two layers, the fabric is lightweight while maintaining good warmth. The connecting layer 3 is woven from hollow fibers and shaped fibers, which enhances overall warmth and comfort while maintaining good loft.

[0032] The surface layer 1 comprises a multi-layer structure comprising a first yarn layer and a second yarn layer. The first yarn layer comprises a plurality of first yarn elements. In the embodiment of the present application, the first yarn elements include long fibers and short fibers. The long fibers are polyester filaments, and the short fibers are cotton fibers. The first yarn elements are interconnected via a connecting structure, which makes the structure more stable. The first yarns can also include different types of yarns, such as FDY and polyester staple fibers. FDY has good tensile strength and low elongation, which gives the raised fabric good windproof performance and thermal insulation. Polyester staple fibers have high abrasion resistance and folding resistance, which improves the resilience of the raised fabric.

[0033] The second yarn layer is composed of multiple second yarn elements. In the embodiment of the present application, the second yarn elements include high-elastic spandex filaments and linen fibers. The use of high-elastic spandex filaments can provide the fabric with better ductility and resilience, which helps to improve the resilience of the raised fabric; while linen fibers can increase the air permeability and moisture absorption of the fabric, which helps to improve the windproof effect of the raised fabric.

[0034] The surface layer 1 and the inner layer 2 are connected by a connecting layer 3, which fixes the surface layer 1 and the inner layer 2 together, provides stability and elasticity, and makes the fabric firm as a whole; the connecting layer 3 includes a plurality of connecting yarn units, and all the connecting yarn units of the connecting layer 3 are interconnected by a connecting structure, ensuring structural stability and integrity. The yarn layers of the surface layer 1 and the inner layer 2 are connected by a woven structure to achieve stability of the surface layer 1 and the inner layer 2, and also have a certain elasticity, making the fabric as a whole more uniform and the appearance more consistent.

[0035] In the embodiment of the present application, the yarn of the connecting layer 3 is made of a polyester yarn with a low thickness of 20 denier to ensure that the fabric remains light and thin while providing a stable connection. The yarn of the connecting layer 3 is connected to the surface layer 1 and the inner layer 2 by an incomplete loop removal method, ensuring the connection stability and the lightness of the material. The yarn of the connecting layer 3 is connected to the coils in the same horizontal row of the surface layer 1 or the inner layer 2 to form multiple suspended arc structures, which increases the fluffiness of the fabric.

[0036] The hollow fiber yarn or shaped fiber yarn in the surface layer 1 is arranged in rows of partially unwound loops. Specifically, the surface layer 1 is provided with multiple rows of partially unwound loops, each row being woven from at least n+1 yarns, where n ≥ 2; in this embodiment, n = 2. Each row is composed of three layers of yarn woven from long and short fibers, forming overlapping loops. The provision of partially unwound loops enhances the density of the coil structure, providing improved warmth while retaining its lightweight properties. Furthermore, the rows are provided with a coil portion and a loop portion. Each row also includes multiple partially unwound loops located at the intersection of the coil portion and the loop portion. The presence of the loops further increases the fabric's bulkiness and enhances the warmth of the surface layer 1.

[0037] The first yarn element and the second yarn element of the inner layer 2 are also connected by a braided structure to ensure structural stability. The transverse density of the coil of the surface layer 1 and the transverse density of the coil of the inner layer 2 are in a ratio of 1.5:1. The inner layer 2 is subjected to a raising process, wherein the temperature is controlled at 40°C, the cloth speed is 15m / min, the clockwise roller speed is 15r / min, and the counterclockwise roller speed is 20r / min.

[0038] The preparation method of the lightweight thick knitted raised fabric in the embodiment of the present application is: using a 36G double-sided circular knitting machine, setting the traction speed to 100r / m, model TF-QS, and specially adjusting the distance between the needle cylinder and the needle disk on the machine to increase the distance between the needle cylinder and the needle disk, that is, the cylinder mouth distance is 0.5mm; ensuring that the tension of the yarn and the mesh size are uniform during the weaving process, thereby ensuring the overall stability of the fabric performance.

[0039] This application achieves lightweight and warm performance by optimizing the design of the surface layer 1, inner layer 2, and connecting layer 3. The surface layer 1 and inner layer 2 utilize adjustable coil sizes to meet different usage requirements, while the connecting layer 3 utilizes hollow fibers and shaped fibers to enhance overall stability and warmth. The combination of different fiber types further enhances the fabric's versatility, making it not only lightweight and warm, but also possessing multifunctional properties such as antibacterial properties.

[0040] This application utilizes a multi-layered design to achieve a tight connection between the surface layer 1 and the inner layer 2 via the connecting layer 3, thereby increasing the overall thickness and thermal insulation performance of the fabric. The multi-layered surface layer 1 and inner layer 2 not only increase the thickness of the fabric but also improve its warmth and comfort. Furthermore, the design of the connecting layer 3 enhances the overall stability and extensibility of the fabric, making it more durable. By adjusting the coil size, the fabric achieves a further balance between warmth and breathability, making it more widely applicable.

[0041] The multi-layer structure of the surface layer 1 can use different yarn materials, such as polyester filament and cotton fiber, to provide different performance advantages, while the multi-layer structure of the inner layer 2 can use fully drawn fiber and cotton fiber to enhance its warmth retention and skin-friendliness. The design of the connecting layer 3 connects the surface layer 1 and the inner layer 2 through a woven structure, making the overall fabric more uniform and firm.

[0042] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
