A double-layer fabric structure with multiple jacquard knitting techniques

Abstract

This utility model discloses a double-layer fabric structure with a multi-jacquard hooking process, including a double-layer fabric body composed of an upper layer and a lower layer. The surface of the double-layer fabric body is provided with a jacquard area, which can be of any shape. The upper and lower layers are connected in the jacquard area by a hooking process. Specifically, the upper and lower layers are connected by hooking the warp yarns. In the jacquard area, the lower warp yarns pass through the upper fabric and interweave with the upper weft yarns to form hook points. The density of hook points is greater at the edges and key parts of the jacquard pattern than in non-jacquard areas. The distribution of these hook points forms a down-filling channel. The down-filling channel formed by the hook point distribution of this utility model allows for subsequent down-filling processing, giving the fabric new functions such as warmth and softness, expanding the application scenarios of double-layer fabrics. The jacquard pattern has a distinct three-dimensional effect, making it more visually appealing than traditional double-layer fabrics.

Description

Technical Field

[0001] This utility model relates to the field of double-layer fabric technology, specifically a double-layer fabric structure using a multi-jacquard knitting process. Background Technology

[0002] In the textile industry, double-layer fabric structures are widely used in clothing, home décor, and other sectors due to their excellent warmth retention and layered texture. Traditional double-layer fabric structures often employ simple stitching or single-connection methods, resulting in limited bonding strength between the upper and lower layers, making delamination common and affecting the fabric's lifespan and performance. Furthermore, they struggle to achieve complex, three-dimensional jacquard patterns, lacking aesthetic appeal and artistry, and failing to meet the modern market's demand for high-end, personalized fabrics. In addition, traditional double-layer fabrics are functionally limited and lack scalability, making it difficult to imbue the fabric with more properties through subsequent processing. Therefore, those skilled in the art have developed a double-layer fabric structure using a multi-jacquard interlocking process to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide a double-layer fabric structure with multiple jacquard knitting processes to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A double-layer fabric structure with a multi-jacquard hooking process includes a double-layer fabric body, which is composed of an upper layer fabric and a lower layer fabric. The surface of the double-layer fabric body is provided with a jacquard area, which is of arbitrary shape. The upper layer fabric and the lower layer fabric are connected in the jacquard area by a hooking process. Specifically, the upper layer fabric and the lower layer fabric are connected by hooking the warp yarns. In the jacquard area, the lower layer warp yarns pass through the upper layer fabric and interweave with the upper layer weft yarns to form hook points. Moreover, the density of hook points is greater than that in non-jacquard areas at the edges and key parts of the jacquard pattern. The distribution of hook points forms a down filling channel.

[0005] Furthermore, in certain locations within the jacquard area, the upper and lower fabrics employ a double-thread jacquard weft interlocking method, where the lower warp yarns simultaneously pass through the upper fabric and interweave with the upper weft yarns to form an interlocking point.

[0006] Furthermore, when the upper and lower fabrics are plain weave, the warp yarn is 30D / 48F polyester low-elasticity yarn, and the weft yarn is 30D / 72F nylon DTY yarn, 35 / 144 polyester low-elasticity yarn + 25D spandex empty yarn, or 50 / 144 polyester low-elasticity yarn + 40D spandex empty yarn.

[0007] Furthermore, when the upper and lower fabrics adopt a 2 / 1 twill weave, the warp yarn is 30D / 48F polyester low-elasticity yarn, and the weft yarn is 30D / 72F nylon DTY yarn, 35 / 144 polyester low-elasticity yarn + 25D spandex blank yarn, or 50 / 144 polyester low-elasticity yarn + 40D spandex blank yarn.

[0008] Furthermore, the jacquard area is also partially covered with 30D spandex yarn.

[0009] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. The down filling channels formed by the distribution of knot points can be used for subsequent down filling treatment, giving the fabric new functions such as warmth and softness, and expanding the application scenarios of double-layer fabric. The upper plain weave and the lower twill weave, combined with specific raw materials, make the fabric have good abrasion resistance, breathability and drape, and its overall performance is better than that of ordinary double-layer fabric.

[0010] 2. By employing a special warp knotting technique in the jacquard area, especially increasing the knotting density at the edges and key parts of the jacquard pattern, and combining it with the elasticity of the spandex-covered yarn, the jacquard pattern has a distinct three-dimensional feel, and can present different pattern states such as wavy or V-shaped connections. It has a wide coverage area, and special methods such as double-line knotting and diagonal knotting further enhance the pattern details, giving the fabric a unique appearance effect that is more visually appealing than traditional double-layered fabric.

[0013] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0014] Please see Figures 1-2This utility model provides an embodiment of a double-layer fabric structure with a multi-jacquard hooking process, including a double-layer fabric body 1, which is composed of an upper fabric 101 and a lower fabric 102. A jacquard area 103 is provided on the surface of the double-layer fabric body 1. The jacquard area 103 has an arbitrary shape. The upper fabric 101 and the lower fabric 102 are connected in the jacquard area 103 by a hooking process. Specifically, the hooking process involves connecting the upper fabric 101 and the lower fabric 102 by hooking warp yarns. In the jacquard area 103, the upper warp yarns pass through the lower fabric 102 and... The lower weft yarns interweave to form hook points, and the density of hook points is greater in the edges and key areas of the jacquard pattern than in the non-jacquard area 103. The distribution of hook points forms the down filling channel 104. In some positions of the jacquard area 103, the upper fabric 101 and the lower fabric 102 adopt a double-thread hooking method, that is, the lower warp yarns pass through the upper fabric 101 and interweave with the upper weft yarns to form hook points. When the upper fabric 101 and the lower fabric 102 adopt a plain weave structure, the warp yarns are 30D / 48F polyester low elastic yarn, and the weft yarns are 30D / 72F nylon DTY. When the upper fabric 101 and the lower fabric 102 adopt a 2 / 1 twill weave, the warp yarn is 30D / 48F polyester low-elastic yarn, and the weft yarn is 30D / 72F nylon DTY yarn, 35 / 144 polyester low-elastic yarn + 25D spandex empty wrap, or 50 / 144 polyester low-elastic yarn + 40D spandex empty wrap. The jacquard area 103 is also partially covered with 30D spandex.The lower warp yarns pass through the upper fabric 101 in the jacquard area 103, interweaving with the upper weft yarns to form hook points. By adjusting the density of these hook points at the edges and key areas of the jacquard pattern, a three-dimensional effect can be achieved, creating different patterns such as wavy or V-shaped connections, with wide coverage. Simultaneously, the 30D spandex covering yarn in the jacquard area 103 provides elasticity, working in conjunction with the warp yarn hooks to make the jacquard pattern partially raised. The distribution of the hook points forms a down-filling channel 104, through which subsequent down-filling treatment can be performed, giving the fabric new properties. In some areas, special methods such as double-line hooks or diagonal hooks are used to further optimize the three-dimensionality and shape of the jacquard pattern. The down-filling channel 104 formed by the hook point distribution can be used for subsequent down-filling treatment, giving the fabric new functions such as warmth and softness, expanding the application scenarios of double-layer fabrics. The upper layer is plain weave. The combination of the weave and the underlying twill weave with specific raw materials gives the fabric excellent abrasion resistance, breathability, and drape, resulting in superior overall performance compared to ordinary double-layer fabrics. A special warp knotting technique is employed in the jacquard area 103, particularly increasing the knotting density at the edges and key areas of the jacquard pattern. Combined with the elasticity of the spandex-covered yarn, this gives the jacquard pattern a distinct three-dimensional feel. Special techniques such as double-line knotting and diagonal knotting further enhance the detail of the pattern, giving the fabric a unique appearance that is more visually appealing than traditional double-layer fabrics.

[0015] During the weaving process, the electronic jacquard machine controls the lower fabric 101 and the upper fabric 101 to be connected in the jacquard area 103 through a warp yarn hooking process according to a preset program. The lower warp yarns pass through the upper fabric 101 in the jacquard area 103 and interweave with the upper weft yarns to form hook points. By adjusting the density of the hook points at the edges and key parts of the jacquard pattern, the three-dimensional effect of the jacquard pattern can be achieved, which can present different pattern states such as wave-like or V-shaped connection, with a wide coverage. At the same time, the 30D spandex covered yarn plays an elastic role in the jacquard area 103, which, together with the warp yarn hooking, makes the jacquard pattern part protrude. The distribution of the hook points forms the down filling channel 104, which can be used for subsequent down filling treatment to give the fabric new characteristics. In some positions, special methods such as double-line hooking or diagonal hooking are used to further optimize the three-dimensionality and shape expression of the jacquard pattern.

[0016] The down-filling channels 104 formed by the distribution of knot points can be used for subsequent down-filling treatment, giving the fabric new functions such as warmth and softness, and broadening the application scenarios of double-layer fabric. The upper plain weave and the lower twill weave, combined with specific raw materials, give the fabric good abrasion resistance, breathability and drape, and its overall performance is better than that of ordinary double-layer fabric. By using a special warp knotting process in the jacquard area 103, especially increasing the knot density at the edges and key parts of the jacquard pattern, and combining it with the elasticity of spandex-covered yarn, the jacquard pattern has a distinct three-dimensional effect. Special methods such as double-line knotting and diagonal knotting further enhance the pattern details, giving the fabric a unique appearance effect, which is more visually attractive than traditional double-layer fabric.

[0017] This specification describes embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
