Description

Technical Field

[0001] This invention relates to a webbing, specifically a knitted webbing with elastic covered yarn as floats. Background Technology

[0002] Elastic webbing is a crucial accessory in the garment industry. Therefore, it demands high standards from manufacturers, considering factors such as hand feel, physical properties, thickness, wash stability, and appearance. Traditional knitted webbing methods sometimes fail to fully address these requirements. For instance, achieving high modulus by thickening the yarn can compromise hand feel; adding a layer of fleece made from nylon / polyester can improve hand feel, but this compromises thickness and wash stability. These are long-standing problems with knitted webbing. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a knitted tape with elastic covered yarn as float.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A knitted tape with elastic covered yarn as float yarn includes a tape body. The tape includes an integrally woven pile layer, a weft layer, and a root yarn layer. The pile layer is located on the surface of the tape body, and the weft layer and the root yarn layer are located inside the tape body. The root yarn layer is disposed between the pile layer and the weft layer and is connected to the pile layer and the weft layer respectively. The pile layer is woven on the surface of the tape using elastic covered yarn in a float yarn process.

[0006] The pile layer is disposed on the upper or lower surface of the webbing body, or the pile layer is disposed on both the upper and lower surfaces of the webbing body.

[0007] The elastic coated yarn includes an outer covering yarn of long or short fibers and an inner spandex filament, wherein the modulus of the outer covering yarn and the inner spandex filament are the same or different.

[0008] The fineness of the outer yarn is ≤300D and DPF is ≤1.18; the fineness of the spandex yarn is ≤1680D.

[0009] The weft layer is woven from nylon, polyester, or elastic covered yarn.

[0010] The root layer is an elastic layer, woven from pure spandex yarn or elastic covered yarn.

[0011] The pile layer, weft layer and root layer are each provided with at least one layer.

[0012] The width of the webbing body is ≥3mm.

[0013] This invention utilizes elastic covered yarn for weaving, which features uniform yarn consistency, smooth yarn with minimal fuzz, and high elastic modulus. The elastic covered yarn is woven onto the surface of the webbing using a float yarn process. Compared to traditional non-elastic covered yarn webbing of the same structure, it not only has a delicate appearance but also maintains a stable washed appearance and exhibits excellent resistance to pilling. Compared to traditional knitted webbing with the same function, its modulus can be adjusted not only by the elastic fibers in the root layer but also by the additional modulus provided by the pile layer yarn. Therefore, its modulus per thickness (MPT) is at least 1% higher than that of traditional webbing with the same structure.

[0014] To achieve a higher modulus, traditional knitted ribbons typically increase the fineness of the elastic fibers in the root layer. However, this increased fineness can affect the ribbon's feel. To improve the feel, a thicker layer of fleece is usually woven into the surface layer using float yarns. This fleece layer is generally made of nylon or polyester yarn. Because nylon or polyester yarn has a relatively loose structure, it is prone to snagging and pilling after washing.

[0015] The elastic covered yarn used in the pile layer of this product is smooth, has low fuzz, and possesses a high modulus of elasticity. Compared to the nylon or polyester versions, this product achieves an increased modulus per unit thickness (MPT) without increasing thickness. Furthermore, the smooth, low-fuzz covered yarn ensures a stable washed appearance and excellent resistance to pilling and fuzzing. This also results in a finer, smoother pile layer, enhancing the overall premium feel. This addresses the pain point of traditional knitted webbing where achieving high modulus often compromises hand feel and pilling resistance. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In the description of this invention, it should be understood that if terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0023] refer to Figure 2 As shown, a knitted tape using elastic covered yarn as float yarn includes a tape body. The tape includes an integrally woven pile layer 1, a weft layer 2, and a root yarn layer 3. The pile layer 1 is located on the surface of the tape body, while the weft layer 2 and the root yarn layer 3 are located inside the tape body. The root yarn layer 3 is positioned between the pile layer 1 and the weft layer 2, and is connected to both the pile layer 1 and the weft layer 2. The pile layer 1 is woven onto the surface of the tape using elastic covered yarn in a float yarn process. Multiple elastic covered yarns can be woven together.

[0024] The pile layer 1 is disposed on the upper or lower surface of the webbing body, or on both the upper and lower surfaces of the webbing body. Utilizing the properties of the elastic covering yarn, it is not prone to pilling or fuzzing even after washing.

[0025] The elastic covered yarn comprises an outer covering yarn of long or short fibers and an inner spandex filament. The outer covering yarn and the inner spandex filament may have the same or different moduli. The outer covering yarn can be nylon or polyester. The spandex filament is wrapped inside to form the elastic covered yarn, resulting in a yarn with uniform evenness, smoothness, low fuzz, and good elasticity. The resulting webbing pile layer not only has a delicate appearance but also maintains a stable washing appearance and exhibits good resistance to pilling and fuzzing.

[0026] The fineness of the outer yarn is ≤300D and DPF is ≤1.18; the fineness of the spandex yarn is ≤1680D.

[0027] The weft layer is woven from nylon, polyester, or elastic covered yarn, preferably elastic covered yarn. This allows the webbing to be horizontally stretchable and 360° stretchable, meeting more needs and creating more possibilities. It also makes wearing the webbing more comfortable and free.

[0028] The root layer is an elastic layer, woven from pure spandex yarn or elastic-covered yarn, with elastic-covered yarn being preferred to improve the dye uptake rate of the webbing. Its fineness can be selected according to the modulus requirements of the product.

[0029] In addition, the pile layer, weft layer and root layer are each provided with at least one layer. When multiple layers are provided, they are superimposed on each other. Two pile layers are provided on the upper surface of the webbing body, and these two pile layers overlap each other.

[0030] like Figure 2 As shown, the pile layer 1 is an elastic covered yarn, with a Pu modulus of M0 in a single elastic covered yarn and a number of covered yarns of N0. The root yarn layer 3 has a Pu modulus of M1 in a single root yarn and a number of root yarns of N1. The webbing thickness is T0 (e.g., ...). Figure 1 As shown), the unit thickness modulus MPT0 of the webbing.

[0031] refer to Figure 1 As shown, this is a traditional webbing woven with non-elastic covered yarn, which also includes a pile layer 10, a weft layer 12, and a root yarn layer 11. The root yarn layer 11 has the same material specifications and number of raw materials as the root yarn layer 3 in this invention. Its webbing thickness is T1, therefore its unit thickness modulus is MPT1.

[0032] When the outer yarn specification of the elastic-covered yarn used in this invention is the same as that of the pile layer material traditionally using non-elastic-covered yarn, the elastic-covered yarn has the characteristics of uniform yarn consistency, smooth yarn, and low fuzz. Therefore, the thickness T0 of the webbing is not increased compared to the thickness T1 of the non-elastic-covered yarn version, and may even be slightly thinner, i.e., T0 ≤ T1. Thus, MPT0 > MPT1, and... Therefore, the knitted tape of the present invention has a modulus per thickness (MPT) that is at least 1% higher than that of conventional structural webbing that achieves the same function.

[0033] When knitting, refer to... Figure 3 As shown, the weaving process of the pile layer 1 (as shown) Figure 3 The elastic covered yarn (as shown in Figure 4) is woven in the form of floating yarns, which are locked and fixed to the surface of the main body of the webbing by the braided loops 6 of the warp yarns. The horizontal movement of the floating yarn is 1-1-1-2-2-2, which is one cycle length. The cycle length can be set according to the actual situation. The longer the length, the stronger the velvety effect.

[0034] Its weft layer has a weft-inserted weave structure. The yarn 7 is moved laterally by N needles according to the designed process (and locked by the warp chain loops 7 to form a planar main body). The width is at least ≥3MM, preferably ≥10MM. The yarn can be made of nylon, polyester, or covered yarn, etc., according to design requirements. If elastic covered yarn is selected, the webbing can be stretched laterally, and 360° stretching can meet more needs and create more possibilities. At the same time, it is more comfortable and free to wear.

[0035] like Figure 3 The core layer has a weft-insulated structure, with the root yarn 5 having a transverse shift number of 1-2. It interweaves with the warp yarn's braided loop 6 to form the root yarn layer of the main body of the webbing, giving the webbing its main elasticity. The raw material can be bare spandex or spandex-covered yarn, and its fineness can be selected according to the modulus requirements.

[0036] It should be noted that the above are merely 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, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
