Description

Technical Field

[0001] The present invention relates to the technical field of textiles, and particularly to a weaving method for a double-layer protective fabric with a tortoise shell-like structure. Background Art

[0002] With the booming development of outdoor cycling activities in recent years, cycling clothing, as an important equipment for cyclists, has not only focused on comfort and breathability, but is also required to have higher safety and protection performance. The fabrics used in traditional cycling clothing mostly focus on functions such as breathability, lightness, wind resistance and waterproofing. However, in high-intensity exercises, especially when collisions or frictions occur, they often cannot provide sufficient protection effects. Especially in high-risk environments such as urban cycling and mountain cycling, cyclists face impacts and abrasions from the ground or other obstacles, and the existing cycling clothing fabrics often have difficulty providing effective abrasion resistance and impact protection.

[0003] Ultra-high molecular weight polyethylene (UHMWPE) materials have gradually become an important choice in the field of protective equipment due to their outstanding abrasion resistance, impact resistance, light weight and high strength. Especially in products such as bulletproof vests, knee pads, and anti-smashing shoes, fabrics made of UHMWPE fibers usually have high tensile strength and are lighter than steel, capable of providing strong protection performance. Although UHMWPE has been applied in some professional protective equipment, there has been no report on the technology of applying it to cycling clothing at present. Summary of the Invention

[0004] Technical problems to be solved: Aiming at the technical problems existing in the background art, the present invention provides a weaving method for a double-layer protective fabric with a tortoise shell-like structure, providing a protective fabric made of ultra-high molecular weight polyethylene (UHMWPE) that can be applied to new cycling clothing, which can not only maintain good comfort and breathability, but also provide excellent protection performance during cycling, meeting the safety needs of cyclists in complex environments.

[0005] Technical solution: A weaving method for a double-layer protective fabric with a tortoise shell-like structure according to the present invention, wherein the double-layer protective fabric is a double-sided pattern fabric with an inside-out layer change, its surface layer is an ultra-high molecular weight polyethylene protective layer presenting a tortoise shell pattern, its inner layer is a wool skin-friendly layer, and its middle flat layer is an ultra-high molecular weight polyethylene tortoise shell bone protective layer. The weaving method includes the following steps: Step 1: Design the fabric organizational structure of the tortoise shell-like pattern; Step 2: Determine the selection of warp and weft yarns, including the material, count, twist, color and their arrangement of the yarns, to ensure that the performance, pattern and visual effect of the fabric meet the design requirements; Step 3: Loom weaving: Warp the wool yarn as the surface and backing warp yarns, and shuttle beat the weft yarns in a cycle with a ratio of 1:1:1 of wool, 800D ultra-high molecular weight polyethylene, and 400D ultra-high molecular weight polyethylene. Adopt the alternating lifting of the surface and backing warp yarns to lay and clamp the intermediate protective layer yarns between the surface and backing double-layer fabrics to form a three-layer double-layer fabric structure with protective performance.

[0006] Preferably, in step 1, based on the lattice pattern in the pattern design, an unequal interval and unequal frequency layer-changing method is adopted to form a symmetric "turtle shell" octagonal graphic structure, and a double-sided structure with yin-yang symmetry of the patterns on the front and back is obtained.

[0007] Preferably, the surface and backing layer-changing of the double-layer protective fabric is carried out in an asymmetric form with unequal intervals and unequal frequencies. Multiple layer-changes are achieved by spacing different warp yarn distances at the same weft yarn, and multiple color-changes are carried out at a certain weft yarn, with frequent alternation of colors A and B.

[0008] Preferably, the double-layer protective fabric uses orange UHMWPE fiber filaments and yellow wool yarn as the surface and backing weft yarns, green UHMWPE fiber filaments as the intermediate layer skeleton yarns, and yellow wool yarn as the surface and backing warp yarns. The surface and backing warp yarns and weft yarns are arranged in a ratio of 1:1. The surface fabric of the obtained double-layer protective structure shows orange-yellow, and the inner layer fabric shows yellow.

[0009] Preferably, the basic weave of the surface and backing of the double-layer protective fabric both adopts plain weave. The surface fabric is formed by plain weave of yellow warp and orange weft, and the main color is orange-yellow. The "turtle shell" octagon is formed by plain weave of yellow warp and yellow weft; the color of the reverse side of the fabric is set oppositely, and the main color is yellow shown by yellow warp and yellow weft. At the "turtle shell" octagon, the surface and backing warp yarns and weft yarns are changed up and down, and the yellow warp and orange weft on the front are changed to the back along the contour line of the pattern design to form an orange-yellow "turtle shell" octagonal structure, forming a pattern with yin-yang relationship on the front and back.

[0010] Preferably, in step 2, select appropriate yarn raw materials and configure appropriate loom processing for weaving on the loom: (1) The loom adopts GS940C loom, the number of warping ends is 5024, the reed is selected as reed No. 73, and 4 ends are inserted into each reed tooth; (2) After the warping process is completed, mount the loom according to the double-layer fabric structure of the turtle shell pattern; among them, the warp yarns are divided into surface warp and backing warp, and the surface and backing warp yarns are arranged in a ratio of 1:1 by selecting soft, moisture-absorbing and sweat-wicking wool yarns; the weft yarns are divided into surface weft, backing weft, and protective skeleton weft, and the surface weft, protective skeleton weft, and backing weft are arranged in a ratio of 1:1:1; the surface tissue and the inner tissue are woven according to the 1 / 1 plain weave; (3) When inserting the protective skeletal weft yarns, all the surface warps are lifted and all the inner warps are lowered. The skeletal weft yarns are clamped between the surface and inner yarns and do not interweave with the fabric to form a flat UHMWPE fiber skeletal protective layer.

[0011] Preferably, when weaving, the weft yarns are inserted in the order of 1 yellow, 1 green, and 1 orange. The warp density is set to 292 threads / 10 cm, and the weft density is set to 400 threads / 10 cm. The actually measured warp density after leaving the loom is 314 threads / 10 cm, and the weft density is 421 threads / 10 cm.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The present invention provides a protective fabric made of ultra-high molecular weight polyethylene (UHMWPE) that can be applied to new cycling clothes. By means of the surface-inner layer changing structure, the UHMWPE fiber material is flatly clamped between the double-layer fabrics to form an independent protective layer, solving the contradiction between the heaviness and poor air permeability of traditional protective materials. This structural design significantly improves impact resistance and wear resistance while maintaining light weight; by combining the high protection of the UHMWPE material with the comfort of wool, the synergistic effect of the two materials is realized through the surface-inner layer changing structure, with both functionality and aesthetics. It can not only maintain good comfort and air permeability but also provide excellent protection performance during cycling, meeting the safety needs of cyclists in complex environments. 2. The double-layer protective fabric adopts a bionic structure, introducing the multi-layer protective structure of a turtle shell (carapace, plastron) into the fabric design to form a three-layer composite structure of "surface protection + intermediate skeletal layer + inner skin-friendly layer"; adopting the weaving process of "unequal intervals and unequal frequencies of layer changing" to achieve the yin-yang symmetric turtle shell octagon pattern on the front and back sides. Through the bionic multi-layer structure, the balance between protection performance and comfort is achieved, and it can be used for outdoor sports protective equipment such as cycling clothes, taking into account high protection, comfort, and aesthetics. 3. The manufacturing method of the double-layer protective fabric adopts the surface-inner layer changing double-layer structure. Through the weft yarn cyclic beating-up (1 yellow, 1 green, 1 orange) and specific harnessing rules (such as alternating lifting of 16 harness frames), precise control of complex patterns and functional layers is achieved. Utilizing the characteristic that different colors can be formed on the front and back sides of the double-layer fabric, by regularly exchanging the front and back yarns according to the flower pattern contour, not only can special pattern patterns be formed but also the effective combination of the upper and lower layers can be realized.

Detailed implementation manners

[0014] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will combine the attached Figures 1 to 8 The technical solutions of the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0015] As Figures 1 to 7 shown, the present invention discloses a weaving method of a double-layer protective fabric with an imitation tortoise shell structure, and the double-layer protective fabric is a double-sided pattern fabric with surface and lining layer exchange; the weaving method includes the following steps.

[0016] (1) Design of the fabric structure of the imitation tortoise shell pattern. The specific steps are as follows: Based on the lattice pattern in the pattern design, an unequal interval and unequal frequency layer exchange method is adopted to form a symmetrical "tortoise shell" octagonal graphic structure, and a double-sided structure with positive and negative patterns showing yin-yang symmetry is obtained; the surface weft yarn and the middle layer skeleton yarn are both made of UHMWPE fiber filaments to provide strong protective performance, and the inner layer weft yarn is made of moisture-absorbing and sweat-wicking wool yarn to meet the requirement of wearing comfort.

[0017] Starting from the lattice pattern in the pattern design, a symmetrical "tortoise shell" octagonal graphic structure is formed, which is specifically manifested as vertical arrangement of rectangular patterns with the same size and the same symmetrical direction, and finally combined into an octagonal geometric pattern, as Figure 2 shown. The surface and lining layer exchange in the fabric appears in an unequal interval and unequal frequency asymmetric form, and multiple layer exchanges are realized at different warp distances at the same weft yarn, and then multiple color changes are realized at a certain weft yarn, with frequent alternation of A and B colors; for example, for the 1st to 4th weft yarns, layer exchange is realized at the 13th warp yarn; and layer exchange is realized again at the 33rd warp yarn. According to the designed pattern, the 1st to 4th weft yarns are layer-exchanged twice in the entire weft cycle, and the A and B color weft yarns are alternately displayed.

[0018] (2) Determine the selection of warp and weft yarns, including the material, count, twist, color, and their arrangement of the yarns, to ensure that the performance, pattern, and visual effect of the fabric meet the design requirements. The double-layer protective fabric uses orange UHMWPE fiber filaments and yellow wool yarn as the surface and inner weft yarns, green UHMWPE fiber filaments as the middle-layer skeleton yarn, and yellow wool yarn as the surface and inner warp yarns. The surface and inner warp and weft yarns are arranged in a 1:1 ratio. The surface fabric of the double-layer protective structure obtained shows orange-yellow, and the inner fabric shows yellow. The basic weave of both the surface and inner layers of the double-layer protective fabric is a plain weave. In one weave cycle, the surface fabric is formed by the plain weave of yellow warp and orange weft, with the main color being orange-yellow. The "turtle shell" octagonal pattern is formed by the plain weave of yellow warp and yellow weft. The color on the reverse side of the fabric is set oppositely. The main color is shown as yellow by yellow warp and yellow weft. At the "turtle shell" octagonal shape, the upper and lower layers of the surface and inner warp and weft yarns are exchanged. The yellow warp and orange weft on the front are changed to the back along the contour line of the pattern design to form an orange-yellow "turtle shell" octagonal structure, forming a pattern with a yin-yang relationship between the front and back sides.

[0019] (3) Loom weaving: Use wool yarn as the surface and inner warp yarns for warping, and use wool, 800D ultra-high molecular weight polyethylene, and 400D ultra-high molecular weight polyethylene with a ratio of 1:1:1 as the weft yarns for cyclic beating-up. Adopt the alternating lifting of the surface and inner warp yarns to sandwich the middle protective layer yarns flatly between the surface and inner double-layer fabrics to form a three-layer double-layer fabric structure with protective performance. The surface layer of the double-layer protective fabric is a ultra-high molecular weight polyethylene protective layer presenting a turtle shell pattern, its inner layer is a wool skin-friendly layer, and its middle flat layer is a ultra-high molecular weight polyethylene turtle shell bone protective layer.

[0020] (4) The specific weaving process of loom weaving is as follows: Select appropriate yarn raw materials and configure appropriate loom processes for weaving on the loom. The loom uses a GS940C loom, and the threading rule is: (1, 2, 3, 4)×2, (5, 6, 7, 8)×2, (9, 10, 11, 12)×2, (13, 14, 15, 16)×10, (9, 10, 11, 12)×2, (5, 6, 7, 8)×2; The number of warping ends is 5024, and a 73-tooth reed is selected, with 4 ends per dent.

[0021] After the warping process is completed, perform loom weaving according to the double-layer fabric structure of the turtle shell pattern. Among them, the warp yarns are divided into surface warp and inner warp. The surface and inner warp yarns are made of soft, moisture-absorbing and sweat-wicking wool yarns and arranged in a 1:1 ratio. The weft yarns are divided into surface weft, inner weft, and protective skeleton yarn. The surface weft, protective skeleton weft yarn, and inner weft are arranged in a 1:1:1 ratio. The surface and inner layers are woven according to the 1 / 1 plain weave. When inserting the protective skeleton weft yarn, all the surface warp yarns are lifted and all the inner warp yarns are lowered. The skeleton weft yarn is clamped between the surface and inner layer yarns and does not interweave with the fabric to form a flat-laid UHMWPE fiber skeleton protective layer.

[0022] Example 1: Specific weaving steps of the embodiment of the present invention: Select appropriate yarn raw materials. The warping process adopts single beam weaving. The warping yarn is white wool yarn. The front and back warp yarns are both selected from the same kind of white wool yarn and arranged in a 1:1 ratio. The fabric weave diagram is as shown in Figure 4 shown. The loom uses a GS940C loom and performs harness threading according to Figure 5 . The harness threading rule is: (1, 2, 3, 4)×2, (5, 6, 7, 8)×2, (9, 10, 11, 12)×2, (13, 14, 15, 16)×10, (9, 10, 11, 12)×2, (5, 6, 7, 8)×2; The number of warping ends is 5024. A reed of No. 73 is selected, and 4 ends are inserted into each reed dent. The fabric draft diagram is input as shown in Figure 6 .

[0023] After the warping process is completed, the loom is set up according to the double-layer fabric structure of the tortoise shell pattern. The front and back warp and weft yarns form a double-layer fabric through the interweaving of the front and back layer changes. The plain weave is used as the basic weave for the front and back layers. Orange UHMWPE fiber filaments are used as the front weft, yellow wool yarn is used as the back weft yarn, and green UHMWPE fiber filaments are used as the middle layer skeleton yarn. The front weft, back weft, and protective skeleton yarn, the front weft, protective skeleton weft yarn, and back weft are arranged in a 1:1:1 ratio; At the same time, yellow wool yarn is used as the front and back warp yarns, and the front and back warp and weft yarns are arranged in a 1:1 ratio. The front layer fabric and the back layer fabric are woven according to the 1 / 1 plain weave. As shown in Figure 3 (a), the front layer fabric is formed by the plain weave of yellow warp and orange weft, and the front layer fabric is mainly in this color tone; Figure 2 The "tortoise shell" octagon in the figure is formed by the plain weave of yellow warp and yellow weft in Figure 3 (b); The color of the back of the fabric is set in the opposite way. The main color tone is yellow shown by yellow warp and yellow weft. At the "tortoise shell" octagon, the front and back warp and weft yarns are changed up and down, and the yellow warp and orange weft on the front are changed to the back along the contour line of the pattern design to form an orange "tortoise shell" octagon structure, forming a pattern with positive and negative yin-yang relationships.

[0024] In this Example 1, the weft yarn makes a cycle of 3 picks during beating-up. At the second pick, 1 green 800D UHMWPE fiber skeleton protective yarn is inserted. At this time, the front warp is lifted and the back warp sinks. The protective yarn is clamped between the front layer and the back layer and does not interweave with the fabric, forming a flat UHMWPE fiber skeleton protective layer. As shown in Figure 7 shown, I is the 800D UHMWPE fiber skeleton yarn, which is always clamped between the front layer and the back layer.

[0025] Example 2: The main difference from Example 1 is that after the warping process is completed, it is mounted on the loom according to the double-layer tissue structure of the tortoise shell pattern structure; the warp and weft yarns of the surface and the lining form a double-layer tissue through surface-lining layer-changing interweaving. The surface warp and the surface weft are woven based on the 1 / 1 plain weave as the basic tissue, and the lining warp and the lining weft are woven based on the 2 / 2 basket weave as the basic tissue. The arrangement ratio of the surface warp to the lining warp is 1:1, and the arrangement ratio of the surface weft to the protective skeleton yarn to the lining weft is 1:1:1. The protective skeleton yarn is clamped between the surface layer and the lining layer through surface-lining layer-changing and does not interweave with the fabric. The grey cloth after being taken off the loom achieves a finished warp density of 335 threads / 10 cm and a finished weft density of 443 threads / 10 cm.

[0026] Example 3: The main difference from Example 1 is that after the warping process is completed, it is mounted on the loom according to the double-layer tissue structure of the tortoise shell pattern structure; the warp and weft yarns of the surface and the lining form a double-layer tissue through surface-lining layer-changing interweaving. The surface warp and the surface weft are woven based on the 1 / 2 twill weave as the basic tissue, and the lining warp and the lining weft are woven based on the plain weave as the basic tissue. The arrangement ratio of the surface warp to the lining warp is 1:1, and the arrangement ratio of the surface weft to the protective skeleton yarn to the lining weft is 1:1:1. The protective skeleton yarn is clamped between the surface layer and the lining layer through surface-lining layer-changing and does not interweave with the fabric. The grey cloth after being taken off the loom achieves a finished warp density of 335 threads / 10 cm and a finished weft density of 443 threads / 10 cm.

[0027] In Example 1 of the present invention, the weft yarn is inserted in the order of 1 yellow, 1 green, and 1 orange during weaving. The warp density is set to 292 threads / 10 cm, and the weft density is set to 400 threads / 10 cm. After being taken off the loom, the actually measured warp density is 314 threads / 10 cm, and the weft density is 421 threads / 10 cm; after the sample weaving, the physical object is as Figure 8 shown, and the physical object coincides with the designed pattern drawing.

[0028] The double-layer protective fabric of the present invention adopts a bionic structure, introducing the multi-layer protective structure (carapace, plastron) of the tortoise shell into the fabric design to form a three-layer composite structure of "surface protection + intermediate skeleton layer + inner skin-friendly layer"; adopting the weaving process of "unequal interval and unequal frequency layer-changing" to achieve the tortoise shell octagon pattern with yin-yang symmetry on the front and back sides, and realizing the balance of protective performance and comfort through the bionic multi-layer structure, and can be used for outdoor sports protection equipment such as cycling clothes, taking into account high protection, comfort and aesthetics.

[0029] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and retouches can also be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
