Abstract
Description
Technical Field
[0001] This invention belongs to the field of textile technology, specifically a cartilage webbing with weft folding and self-healing functions. Background Technology
[0002] During human movement, the skin undergoes complex dynamic flexing changes. Traditional webbing products such as shoulder straps, armbands, and waistbands, while increasing elastic modulus, often result in thicker and stiffer webbing. This characteristic creates a contradiction between "rigid support" and "flexible feel" in dynamic contact with the skin, severely impacting wearing comfort. While high-modulus webbing provides stable support, its stiff feel and compressive deformation can easily cause skin marks and restrict freedom of movement. On the other hand, while low-modulus webbing conforms better to the body's curves, its insufficient support makes it prone to displacement and deformation during use, failing to meet functional requirements. This contradiction is particularly pronounced in sportswear and medical protective gear, where current technology struggles to achieve both sufficient support and good flexibility and comfort. Furthermore, traditional webbing is prone to permanent deformation after repeated folding, affecting its lifespan and appearance. Therefore, existing technologies urgently need improvement to address these issues. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention provides a cartilage webbing with latitudinal folding and self-healing functions.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A cartilage webbing with weft folding and self-healing functions includes a webbing body. The webbing body includes several periodically arranged multiple composite modules in the warp direction. The multiple composite modules include a first warp group and a second warp group. The first warp group and the second warp group interweave with each other to form an X-shaped structure between two adjacent weft yarns. This results in the first warp group and the second warp group forming two stable warp angles and two stable warp angles at the interlacing position, as well as a first folding variable angle and a second folding variable angle in the weft direction. The first stable angle is filled by the first warp group, and the second stable angle is filled by the second warp group. The first folding variable angle and the second folding variable angle are not filled by warp yarns in the weft direction, forming empty angles.
[0006] As a further improvement, the first warp group includes elastic core-spun yarn A1, warp yarn A2 and elastic core-spun yarn A3 arranged in sequence; the second warp group includes elastic core-spun yarn B1, warp yarn B2 and elastic core-spun yarn B3 arranged in sequence, with core-spun yarn A1, warp yarn A2, elastic core-spun yarn A3, elastic core-spun yarn B1, warp yarn B2 and elastic core-spun yarn B3 respectively connected and bound to the weft yarn.
[0007] As a further improvement, when the webbing body is not subjected to external force, the first stable angle and the second stable angle are ≥1° and ≤90°; the first folding variable angle and the second folding variable angle are ≥90° and <180°.
[0008] As a further improvement, warp A2 in the first warp group contains at least one yarn, and warp B2 in the second warp group contains at least one yarn.
[0009] As a further improvement, the upper and / or lower surfaces of the webbing body are woven with jacquard layers.
[0010] As a further improvement, the main body of the webbing is an elastic webbing or a non-elastic webbing.
[0011] As a further improvement, the number of yarns in warp group A and warp group B is the same.
[0012] The present invention has the following beneficial technical effects:
[0013] The X-shaped structure and empty angle design formed by the periodically arranged multiple composite modules enable latitudinal folding through variable angles when under force. When a latitudinal load is applied, the angle generates directional deformation without additional resistance, causing the fold to form a latitudinal boneless state, achieving the cartilage characteristics that facilitate folding. After the external force is removed, the original shape is automatically restored through the stable angle, which improves flexibility while maintaining support. It has the advantages of reducing skin marks, increasing freedom of movement, and extending service life. Attached Figure Description

[0020] like Figure 1As shown, a cartilage webbing with weft folding and self-healing functions includes a webbing body. The webbing body comprises several periodically arranged multi-composite modules along the warp direction. Each multi-composite module includes a first warp yarn group A and a second warp yarn group B. The first warp yarn group A and the second warp yarn group B interweave to form an X-shaped structure between adjacent weft yarns. This results in two stable warp angles ∠1 and ∠3 at the interlacing points, and a first variable folding angle ∠2 and a second variable folding angle ∠4 along the weft direction. The first stable angle is filled by the first warp yarn group, and the second stable angle is filled by the second warp yarn group. The first and second variable folding angles are not filled by warp yarns along the weft direction, forming empty angles. Under the periodic interlacing of the multiple interlacing composite units, adjacent weft yarns in each warp yarn group form multiple characteristic X-shaped structural angles along the weft direction after any two adjacent weft passes. When a weft load is applied, the first and second fold variable angles generate directional deformation without additional resistance, causing the fold angles to deflect in synergy. Through the deformation energy storage generated by the self-constraint force of the first and second warp yarn groups, the gradient release of fold stress is realized, constructing a dynamic force balance system to ensure the structural stability of the webbing under normal conditions.
[0021] The cartilage described in this application refers to the directional deformation that occurs when a latitudinal load is applied, without additional resistance at the included angle, causing folding to form a latitudinal boneless state, while being unrestrained in the latitudinal direction.
[0022] Multiple composite modules refer to unit structures arranged repeatedly in the warp direction. Specifically, this can be achieved by alternating weaves of two sets of warp yarns to form a periodic distribution, with each module constituting an independent deformation unit. An X-shaped structure refers to the geometric shape formed by the intersection of two sets of warp yarns, which can be achieved by changing the warp yarn interlacing order. This structure can produce directional deformation under stress. A stable warp angle refers to the fixed angle range formed by the warp yarn set at the interlacing point, used to maintain structural rigidity. A variable weft folding angle refers to the open angle region not filled by warp yarns. Specifically, this can be achieved by adjusting the warp yarn density to create empty spaces, allowing weft folding deformation.
[0023] Specifically, the two sets of warp yarns form intersections during interlacing, creating four angles at each intersection. Two warp angles are filled by the warp yarns to form a support structure, while the two weft angles remain empty. When an external force is applied to the webbing, the empty angle areas undergo folding deformation, and the warp yarns absorb energy through elastic deformation. After the external force disappears, the elastic warp yarns push the angles back to their initial state, thus creating a weft-oriented folding characteristic. This application uses grouped warp yarns to form an alternating support structure, maintaining warp stability while providing deformation space for dynamic bending at the weft empty angles. The X-shaped interlacing structure makes the folding deformation directionally controllable, and the elastic warp yarns endow it with self-recovery capability.
[0024] The first warp group A includes elastic core-spun yarn A1, warp yarn A2, and elastic core-spun yarn A3 arranged in sequence; the second warp group includes elastic core-spun yarn B1, warp yarn B2, and elastic core-spun yarn B3 arranged in sequence. Core-spun yarn A1, warp yarn A2, elastic core-spun yarn A3, elastic core-spun yarn B1, warp yarn B2, and elastic core-spun yarn B3 are respectively connected and bound to the weft yarns. This connection and binding refers to the weaving process that creates interlacing points between the warp and weft yarns, specifically using plain weave or twill weave structures. This structure ensures that the elastic core-spun yarn and the rigid warp yarn work synergistically under stress.
[0025] Specifically, elastic core-spun yarn A1, warp yarn A2, and elastic core-spun yarn A3 are arranged alternately to form the first warp yarn group, and elastic core-spun yarn B1, warp yarn B2, and elastic core-spun yarn B3 are arranged alternately to form the second warp yarn group. When the weft yarns interweave with each warp yarn group, the elastic core-spun yarns absorb external forces through tensile deformation, while the rigid warp yarns maintain the main shape of the webbing. For example, during weft folding, the elastic core-spun yarns A1, A3 and B1, B3 undergo elastic deformation to close the empty angle, while the warp yarns A2 and B2 restrict excessive deformation through rigid support. After the external force is removed, the restoring force of the elastic core-spun yarns drives the empty angle to unfold again, achieving a self-recovery function. Through the alternating arrangement and binding connection of elastic and rigid materials, the webbing maintains structural stability and can automatically recover when subjected to pressure.
[0026] When the main body of the webbing is not subjected to external force, the first stable angle and the second stable angle are greater than or equal to 1 degree and less than or equal to 90 degrees; the first folding variable angle and the second folding variable angle are greater than or equal to 90 degrees and less than 180 degrees.
[0027] Specifically, when the webbing is not subjected to external forces, the stable angle formed by the warp yarns is controlled between 1 and 90 degrees, ensuring the webbing maintains its basic support and prevents collapse. Simultaneously, the variable folding angle between the weft yarns is set between 90 and 180 degrees. When a weft load is applied, no additional resistance causes directional deformation, resulting in a coordinated deflection of the folding angle. When external forces are applied to the webbing, the variable folding angle absorbs deformation through angular contraction, while the stable angle maintains structural integrity through the restoring force of the elastic core-spun yarn. After the external force is removed, the contraction of the elastic core-spun yarn restores the variable folding angle to its initial angle range.
[0028] The first warp group contains warp A2, which contains at least one yarn, and the second warp group contains warp B2, which contains at least one yarn. The main body of the webbing is an elastic webbing or a non-elastic webbing.
[0029] The upper and / or lower surfaces of the webbing body are woven with jacquard layers to increase the decorative properties of the webbing.
[0030] This application constructs an X-shaped angle collaborative system: a stable included angle providing support, formed by the binding of elastic core-spun yarns, warp yarns, and weft yarns; and a variable folding angle, an empty area without warp yarn filling, allowing free deformation under weft loads. Dynamic balance control: the constraint forces between warp yarn groups create dynamic force balance, ensuring structural stability under normal conditions; the empty angle deflects collaboratively under load, achieving directional folding deformation. Through the synergistic effect of multiple composite modules, the system simultaneously achieves: utilizing the free deformation characteristics of the empty angle to create easy weft folding characteristics; releasing energy stored in the warp yarns to achieve self-recovery capability; and maintaining structural stability using the stable included angle.
[0031] Specific preparation:
[0032] It is produced using a conventional shuttle loom.
[0033] 1. Preparation of the wrapping root
[0034] Double-wrapped yarn is made of 280D spandex and 40D / 1SD nylon, with the core layer being 280D spandex and the covering yarn being 40D / 1 nylon, forming an elastic core-spun yarn X28099 / 40.
[0035] The warp preparation involves categorizing and winding the warp yarns for the ribbon onto a warp beam for pre-weaving preparation. The warp yarns are 40D / 2 nylon and X280 99 / 40. There are 70 elastic core-spun yarns and 110 40 / 2 nylon yarns. All warp yarns are warped and prepared into a warp head.
[0036] 2. Wear brown
[0037] according to Figure 2 The warp yarns are arranged in the order shown in the diagram, so that all the warp yarns pass through the palm fiber holes. Figure 2 The numbers "1, 2, 3..." in the small and medium squares represent the brown frame sequence number; the numbers "↑3↑4↑5↑..." in the arrow squares represent the order in which the warp yarns enter the reed.
[0038] 3. Production density
[0039] The fabric density in this embodiment is 13.3 needles / cm.
[0040] 4. Width and reed
[0041] In this embodiment, the width is 13 mm, the reed specification is 25 (i.e., 25 squares per inch), and a total of 13 squares are used. (According to...) Figure 2 The reed insertion sequence shown in the diagram involves inserting the warp yarns into the designated grid positions on the reed.
[0042] 5. Weft yarn
[0043] In this embodiment, the weft yarn is one 75D / 1 polyester yarn.
[0044] 6. Laws of Movement in Organizational Structure
[0045] like Figure 3 As shown in the diagram, the weave structure of this example is arranged according to the pattern chain. Lines 1, 2, 3, and 4 are elastic core-spun yarn structures with a 1-up, 1-down weave. Lines 5, 6, 7, 8, 9, 10, 11, and 12 have 3-up, 1-down and 3-down, 1-up weave structures, respectively. The 75D / 1 weft yarn passes through the weft conveyor, passing one above and one below the weft hook. The weft hook drives the weft yarn across the opening formed by the warp yarns driven by the hard hem pattern chain, and then the weft yarn is collected by the latch needle. The reed swings back and forth to compact the weft yarn passing through the warp opening.
[0046] 7. The rubber roller, driven by the density adjustment device, pulls the warp yarns after beveling to form a webbing.
