Technical Field
[0001] This invention relates to the field of ribbon manufacturing technology, specifically to an elastic shuttle ribbon and its preparation method. Background Technology
[0002] Most webbing on the market is rigid but lacks elasticity. This type of non-elastic rigid webbing is quite stiff and does not easily deform under stress. It is often used in trousers in conjunction with belt buckles to tighten the waistband. However, when the wearer bends over or squats, this non-elastic rigid webbing compresses the wearer's abdomen, thus affecting the wearer's comfort. To address this issue, the industry considered replacing the non-elastic rigid webbing with elastic webbing. However, elastic webbing is too soft and cannot work with belt buckles to tighten the waistband, resulting in poor practicality and failing to meet the wearer's daily needs. Summary of the Invention

Attached Figure Description
[0023] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0024] Figure 1 This is a schematic diagram of the structure of this elastic woven tape; Figure 2 This is a schematic diagram of the trajectory of the weft yarn in this invention; Figure 3 This is a schematic diagram of the warp yarn arrangement sequence in this invention; Figure 4 This is a floral diagram of the tissue structure of the present invention. Detailed Implementation
[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.
[0027] This embodiment relates to a method for preparing an elastic woven tape, referring to... Figures 1-4 The process includes the following steps: using a weaving process to vertically interweave warp and weft yarns to form a webbing with a varied structure; wherein the warp yarns are elastic yarns. Specifically, the weaving process ensures a more stable, crisper, and tighter webbing structure, giving the webbing a certain rigidity to adapt to scenarios requiring support, such as belt buckles. The varied weaving structure mimics the appearance of knitted rib, giving the webbing a certain textured surface. The use of elastic warp yarns provides basic elasticity, giving the webbing a certain degree of elasticity, allowing it to stretch and contract according to the wearer's body position, avoiding excessive pressure on the wearer's body, and improving wearing comfort and practicality. In this embodiment, the varied structure can be a plain weave, a varied twill weave, etc.
[0028] Furthermore, in the step of using a shuttle weaving process to vertically interweave warp and weft yarns to form a webbing with a variable structure, the shuttle path of the weft yarn is 3-7 / 4-8 / 5-9 / 6-10; the warp yarn threading sequence is 12 / 343 / 1565; and the warp yarn threading trajectory changes as RRXXXRXXX, where R and X represent threading in and threading out, respectively. By limiting the shuttle path of the weft yarn, the threading sequence of the warp yarn, and the changes in the warp yarn threading trajectory, a specific shuttle weaving variation structure is created on the webbing, giving it a ribbed textured effect. This results in a stronger textured surface on the side of the strap (the side facing away from the wearer), and a better fit with belt buckles, etc. It should be noted that the numbers in the weft yarn shuttle path represent the record of the weft yarn's shuttle path within the gaps between the heald frames on the loom. The numbers indicate the heald frame number (the heald frame is a component on the loom that controls the raising and lowering of the warp yarns and creates openings for the weft yarn to pass through). Specifically, 3-7 indicates that the weft yarn passes from the warp opening gap corresponding to heald frame 3 to the warp opening gap corresponding to heald frame 7; 4-8 indicates that the weft yarn passes from the warp opening gap corresponding to heald frame 4 to the warp opening gap corresponding to heald frame 8; 5-9 indicates that the weft yarn passes from the warp opening gap corresponding to heald frame 5 to the warp opening gap corresponding to heald frame 9; 6-10 indicates that the weft yarn passes from the warp opening gap corresponding to heald frame 6 to the warp opening gap corresponding to heald frame 10; the ' / ' symbol represents a path separator, indicating that after completing one shuttle path, the weft yarn enters the next different movement path. In the warp threading trajectory variation, R and X represent threading (the warp yarn at the corresponding position needs to be threaded into the specified heald frame or reed teeth) and skipping (the warp yarn at the corresponding position does not thread into that group of heald frames or reed teeth), respectively. The warp threading sequence is 12 / 343 / 1565, which indicates that the warp yarn is threaded into multiple repeating heald frame sequences, including double-heald frame segments, triple-heald frame repeating segments, and quadruple-heald frame repeating segments, to form the heald frame control sequence required for the varied weave. The numbers represent the heald frame numbers.
[0029] In this embodiment, the shuttle path of the weft yarn is defined as 3-7 / 4-8 / 5-9 / 6-10; the warp yarn threading sequence is 12 / 343 / 1565; the warp yarn threading trajectory changes as RRXXXRXXX; and the opening modulus is 35% / 4.25KG. The webbing woven on the NF8 / 27 / 20 high-speed shuttle loom by the shuttle weaving process has a variable twill structure.
[0030] Furthermore, before the step of using a shuttle weaving process to interweave warp and weft yarns perpendicularly to form a webbing with a varied structure, the method further includes: laying out the warp yarns, referring to... Figure 3The warp yarn arrangement sequence is: 1o, 3X, ... o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o, 3X, 1o; where 'o' represents 560D / 75D / 2, and 'X' represents polyester FDY300D / 96F. The numbers represent the heald frame number. A fixed yarn arrangement order ensures uniform weave texture and consistent rigidity, avoiding uneven local softness and hardness. 560D / 75D / 2 indicates: spandex specification 560D, wrapped with two layers of the same specification black polyester DTY75D / 36F yarn. The term FDY300D / 96F refers to fully drawn polyester filament with a fineness of 300D and a porosity of 96F, which is less prone to loosening at the cut edge, thus improving the stability of the webbing edge. In some embodiments, the polyester can also be DTY300D / 96F / heavy web Z-twist.
[0031] Furthermore, referring to Figure 4 Before the step of using a shuttle weaving process to vertically interweave warp and weft yarns to form a ribbon with a varied structure, and after the step of arranging the warp yarns, the process further includes: dividing the warp yarns into upper and lower distinct sheds by driving the heald frame with a flower chain, wherein the flower chain arrangement order includes: The order of the floral arrangement in the first horizontal row is as follows:
[0032] The order of the second row of floral patterns is as follows:
[0033] The order of the flower chains in the third horizontal row is as follows:
[0034] The order of the flower chains in the fourth row is as follows:
[0035] The order of the floral arrangement in the 5th horizontal row is as follows:
[0036] The order of the floral chain in the 6th row is as follows:
[0037] The order of the floral arrangement in the 7th horizontal row is as follows:
[0038] The order of the floral chain in the 8th row is as follows:
[0039] Where X indicates that the meridian is raised above the latitude line. This indicates that the meridian falls below the parallel of latitude.
[0040] The numbers represent the heddle frame numbers. During the weaving process, following the above pattern chain arrangement, the warp yarns form a regular undulation, resulting in a webbing surface with a distinct ribbed texture that better fits the belt buckle. Simultaneously, the tight heddle-lifting cycle increases the number of yarn interlacing points, making the webbing structure denser and ensuring sufficient rigidity.
[0041] Optionally, the elastic yarn can be any one of spandex filament, spandex core-spun yarn, spandex covered yarn, polyester high-elastic yarn, and nylon high-elastic yarn. In this embodiment, the elastic yarn is spandex core-spun yarn, that is, the weft yarn is spandex core-spun yarn, which has superior resilience and high elongation, while also being softer to the touch and making the overall elasticity of the webbing more uniform. The outer layer fibers in the spandex core-spun yarn prevent the spandex from being directly exposed, greatly improving the abrasion resistance and durability of the webbing and preventing the spandex from being scratched or aged by direct ultraviolet radiation.
[0042] In some embodiments, the elastic yarn may also be spandex yarn, spandex-covered yarn, polyester high-elastic yarn, or nylon high-elastic yarn.
[0043] Furthermore, the spandex core-spun yarn consists of 6-8% spandex and 92-94% polyester to ensure both rigidity and elasticity, guaranteeing moderate rebound strength of the webbing during use and preventing it from becoming loose during strenuous exercise.
[0044] Furthermore, the spandex content can be 6%, 7%, or 8%, and the polyester content can be 92%, 93%, or 94%. It is sufficient that the spandex content is between 6-8% and the polyester content is between 92-94%; no specific restrictions are imposed. In this embodiment, the spandex core-spun yarn contains 7% spandex and 93% polyester; the spandex is 560D / 75D / 2, and the polyester is DTY300D / 96F / heavy-net Z-twist. In this embodiment, the warp yarn is FDY300D / 96F polyester yarn. In addition, the polyester is undyed black, requiring no dyeing before direct weaving, resulting in good colorfastness and faster weaving efficiency.
[0045] Furthermore, the spandex fineness ranges from 560 to 1120D. In this embodiment, the spandex fineness is 560D to ensure sufficient resilience. In some embodiments, the spandex fineness can also be 840D or 1120D. It is sufficient that the spandex fineness is between 560 and 1120D; no specific limitation is made here.
[0046] Furthermore, the weft density of the webbing ranges from 12.3 to 13.7 weft / cm to improve its abrasion resistance, pilling resistance, and rigidity, thereby extending its service life and preventing it from being too soft to fit with belt buckles, etc. In this embodiment, the weft density of the webbing is 12.7 weft / cm. In some embodiments, the weft density of the webbing can also be 12.3, 13, or 13.7 weft / cm. It is sufficient that the weft density ranges from 12.3 to 13.7 weft / cm; no specific limitation is imposed here.
[0047] Furthermore, after the step of dividing the warp yarns into two distinct sheds by driving the heald frame with a flower chain, the process also includes: post-treatment, where the webbing is set at 130-190°C at a speed of 45-50 rpm to achieve high-temperature setting and ensure long-lasting and stable elasticity. In this embodiment, after the webbing is woven, it is set at 130°C at a speed of 48 rpm, using the heat and moisture effects of steam and water to stabilize the webbing shape. This method has minimal impact on the dye and webbing structure, maintaining the original color and luster of the webbing. In some embodiments, setting can also be performed at 140°C or 150°C, and the rotation speed can also be 45 rpm or 50 rpm. No specific limitations are imposed here.
[0048] This embodiment also relates to an elastic woven tape, manufactured using the elastic woven tape preparation method described above. Compared to traditional elastic tapes, this elastic woven tape combines rigidity and elasticity, has a more stable and stiffer structure, is less prone to snagging and deformation, and has good abrasion resistance. Compared to traditional rigid tapes, this elastic woven tape has a certain degree of elasticity, reducing the feeling of restriction on the wearer.
[0049] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
