Abstract
Description
Technical Field
[0001] This application belongs to the field of textile technology, specifically relating to warp-knitted elastic webbing and textiles. Background Technology
[0002] Integrated weaving techniques for creating buttonholes are widely used in the market, with various technologies available for both woven and knitted fabrics. This weaving technology allows buttonholes to be formed directly during the weaving process, eliminating the need for subsequent processing, thus improving production efficiency and reducing costs.
[0003] In existing buttonhole webbing, the buttonhole is formed by four sets of yarns: top, bottom, left, and right. When the buttonhole is opened, the yarns on the left and right sides slide to the sides, resulting in long floating yarns on the top and bottom sides. When the buttonhole retracts, the yarns on the left and right sides cannot automatically return to their original positions, and the long floating yarns on the top and bottom sides accumulate and bulge, forming yarn balls, which seriously affects the appearance and performance.
[0004] The problem of yarn not returning to its original position and the accumulation of loose yarn when the buttonhole retracts after being opened leads to a shortened lifespan, reduced appearance quality, and poor user experience, thus limiting the application of buttonhole webbing in high-end products.
[0005] Therefore, how to solve the problem of yarn not returning to its original position and the accumulation of loose yarn when the buttonhole is opened and then retracted has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0041] In the description of this application, 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", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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 this application.
[0042] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0044] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0045] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0046] The term "pattern rule" is used in the following example: 2-3-2-2-3-1-3-2-3-2-3-1-3-2-2-3-2-3. Each number in the pattern refers to the gear model in the warp knitting machine that controls the lateral movement distance of the guide bar. The initial position is usually defined as 1. 2-3 means that the guide bar moves one needle position to the left, 3-1 means that the guide bar moves two needle positions to the right, 2-7 means that the guide bar moves five needle positions to the left, 2-2 means that the guide bar remains stationary, and so on. This meaning is a consensus in the industry.
[0047] The term "wrap" refers to a very common and important type of textile yarn, which is a composite yarn consisting of an elastic fiber, usually spandex or latex filament, as the core yarn, and one or two layers of non-elastic polyester filament, nylon filament, or staple fiber spirally wrapped around it.

[0050] The first weft yarn 111 includes elastic covering yarn, which forms the first part of the buttonhole 11 according to the first pattern;
[0051] The second weft yarn 112 includes elastic covering yarn, which forms the second part of the buttonhole 11 according to the second pattern;
[0052] The first part of the button and the second part of the button together form a circle around the button 11;
[0053] The pattern of the first flower chain is (2-3). x ,2-3,2-2-3-1,(3-2) x ,3-2,3-1-3-2; The second floral pattern is (1-2). x ,1-2,1-3,(1-2) x,1-2,1-3, where x is the number of repetitions of the chain and x is a positive integer.
[0054] For example, the first flower chain pattern is 2-3-2-2-3-1-3-2-3-2-3-1-3-2-2-3-2-3; the second flower chain pattern is 1-2-1-2-1-3-1-2-1-2-1-3-1-2-1-2-1-2.
[0055] In one embodiment, the pattern of the first weft yarn pattern is 2-3-2-2-3-1-3-2-3-2-3-2-3-2-3-2-3-1-3-2-2-3-2-3; the pattern of the second weft yarn 112 pattern is 1-2-1-2-1-3-1-2-1-2-1-2-1-2-1-3-1-2-1-2-1-3-1-2-1-2-1-2.

[0062] The second weft yarn 112 pattern chain is 1-2-1-2-1-3-1-2-1-2-1-2-1-2-1-2-1-3-1-2-1-2-1-2.
[0063] like Figure 2 As shown, by controlling the specific flower chain, the elastic wire can form a stable edge structure of the button 11, ensuring the stability and resilience of the button 11 during the expansion and contraction process.
[0064] It is understandable that the buttonholes can be located at any number of positions along different axes of the webbing, and the buttonhole lengths and spacings can be different.
[0065] In some embodiments, the warp yarn is a polyester filament of 75D / 1, 100D / 1, 150D / 1, or 75D / 2; the polyester warp yarn 100 has good strength and abrasion resistance, which can provide stable structural support for the webbing, and at the same time, it works with the elastic yarn to form a stable buttonhole 11 structure.
[0066] In some embodiments, the first weft yarn, the second weft yarn, and the third weft yarn are each independently selected from one or both of the following: rooted elastic yarn and wrapped elastic yarn.
[0067] In some embodiments, the first weft yarn is an elastic yarn of 420 / 75D / 1 / 30 / 2 / P, 420 / 75D / 1 / 40 / 2 / P, 280 / 40D / 1 / 33 / 2 / N, latex yarn #37, or spandex yarn #1680D. Wherein: 420: represents the total denier of the elastic fiber (such as spandex), i.e., the elastic fiber thickness is 420D; 75D: represents the denier of the yarn covering the elastic fiber as 75D; 1: represents the elastic fiber as a single strand; 30: represents the maximum stretch of 10CM of the elastic covered yarn in its natural state to 30CM; 2: represents the elastic fiber covered yarn as a double strand; P: represents the type of covered yarn as polyester (commonly P: Polyester, N: Nylon). In some embodiments, the second weft yarn 112 is an elastic yarn of 420 / 75D / 1 / 30 / 2 / P or 420 / 75D / 1 / 40 / 2 / P. In some embodiments, the third weft yarn 110 is an elastic yarn of 420 / 75D / 1 / 30 / 2 / P or 420 / 75D / 1 / 40 / 2 / P.
[0068] Among them, the elastic yarn has good elasticity and wear resistance, and can withstand repeated stretching and shrinkage, thus extending the service life of the button 11.
[0069] In some embodiments, a fourth weft yarn 121 and a fifth weft yarn 122 are also included. The fourth weft yarn 121 is made of polyester filament and is wefted according to the fourth flower chain pattern. As the fourth part of the buttonhole perimeter, it together with the first part, the second part and the third part of the buttonhole to form the perimeter of the buttonhole 11.

[0071] In some embodiments, the fourth flower chain pattern is (1-N*)x, 1-N*, (2-N*)x, 1-N*; the fifth flower chain pattern is (1-N*)x, 1-N*, 1-(N*+1)x, 1-(N*-1); where x is the number of times the chain repeats, and x is a positive integer; and N* is a positive integer.
[0072] In some embodiments, the fourth flower chain pattern is a cycle of 1-5-1-5-2-5-2-5-2-5-2-5-1-5-1-5-1-5.
[0073] In some embodiments, the fifth flower chain pattern is a cycle of 1-4-1-5-1-4-1-4-1-4-1-4-1-5-1-4-1-4.
[0074] In some embodiments, the fourth weft yarn pattern chain is 1-5-1-5-2-5-2-5-2-5-2-5-2-5-2-5-2-5-1-5-1-5-1-5; and the fifth weft yarn pattern chain is 1-4-1-5-1-4-1-4-1-4-1-4-1-4-1-4-1-4-1-5-1-4-1-4-1-5-1-4-1-4.
[0075] In some embodiments, the fourth weft yarn 121 is a polyester filament of 75D / 1, 100D / 1, 150D / 1, or 75D / 2. In some embodiments, the fifth weft yarn 122 is a polyester filament of 75D / 1, 100D / 1, 150D / 1, or 75D / 2.
[0076] In some embodiments, the elastic wire has an elongation rate of ≥50%. The high elongation rate of the elastic wire ensures that the button 11 has sufficient room to stretch when it is opened, and at the same time provides sufficient rebound force when it is retracted, so that the button 11 can fully return to its original shape, avoiding the problem of deformation or incomplete recovery of the button 11 due to insufficient rebound force.
[0077] This application also provides a textile fabric, at least a portion of which is made using the aforementioned warp-knitted buttonhole elastic webbing 10.
[0078] In some embodiments, the textile includes one or more of clothing, medical bandages, and seating fabrics. The textile has good resilience and can fully recover its original shape after use.

[0117] This comparative example provides a conventional warp-knitted buttonhole 20 webbing and a method for preparing the webbing.
[0118] The raw materials used in the preparation of traditional warp-knitted buttonhole ribbons include:
[0119] Warp yarn: 150D polyester / 1.
[0120] Weft yarn: Latex yarn 37# and polyester 150D / 1.
[0121] The traditional method for preparing warp-knitted buttonhole 20 ribbon includes the following steps:
[0122] The weaving process uses warp yarn 200, third weft yarn 210, fourth weft yarn 221, and fifth weft yarn 222.
[0123] Among them, polyester 150D / 1 is used as warp yarn 200, latex yarn 37# is used as the third weft yarn 210, and polyester 150D / 1 is used as the fourth weft yarn 221 and the fifth weft yarn 222.
[0124] Controlling the weft yarn laces on different comb bars:
[0125] The third weft yarn 210 pattern chain has a 1-2 cycle.
[0126] The fourth weft yarn 221 pattern chain is 1-5-1-5-2-5-2-5-2-5-2-5-2-5-2-5-2-5-1-5-1-5-1-5-1-5.
[0127] The fifth weft yarn 222 pattern chain is 1-4-1-5-1-4-1-4-1-4-1-4-1-4-1-4-1-4-1-5-1-4-1-4 in one cycle.
[0128] Button gate deformation test: Thread the drawstring through the button gate and pull the drawstring to stretch the button gate to 200% of its original length. Hold for 10 seconds and then release. Check the degree of deformation after the button gate recovers and observe whether there are any phenomena such as loose yarn, yarn balls, or deformation.
