Description

Technical Field

[0001] This application relates to the field of woven fabric technology, specifically to a deformation-resistant webbing and garment. Background Technology

[0002] Webbing, as a fundamental and important flexible textile structural component, is widely used in clothing accessories, bag straps, and other fields. Currently, conventional webbing often uses a uniform material and weave structure (such as plain weave or twill weave) woven along its width. While this homogeneous design performs adequately under normal usage conditions, after long-term or repeated stress, the yarns are prone to slippage, and the webbing structure undergoes creep, causing the webbing to elongate, narrow, or fail to return to its original size, affecting its reliability and service life. To improve deformation resistance, the industry often attempts to uniformly incorporate high-modulus, low-creep deformation-resistant yarns (such as polyester industrial yarn or aramid) throughout the webbing. However, while this global reinforcement method can improve overall stiffness, it often comes at the cost of sacrificing the necessary flexibility and fit of the webbing, and significantly increases costs, failing to achieve an optimal balance between performance and cost, and rigidity and flexibility.

[0003] In twill weave tape, due to the inherent directionality of the twill structure, the tape is prone to curling or twisting along its length when subjected to tension, humidity changes, or internal stress release. This deformation not only severely affects the tape's appearance and feel, but also results in uneven stress distribution across the tape's width under load, with edge areas typically bearing greater friction and stress. Homogeneous tape edges, lacking targeted reinforcement, are more susceptible to wear, pilling, and even breakage. Furthermore, when subjected to lateral forces or localized compression, the uniform overall structural response easily leads to persistent longitudinal wrinkles, particularly noticeable when worn close to the skin, affecting both aesthetics and comfort. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes: An anti-deformation webbing includes: a webbing body, the webbing body being woven with warp and weft yarns to form a twill weave, wherein the warp and weft yarns are respectively composed of textile yarns and anti-deformation yarns; the webbing body includes a main region and edge regions disposed on both sides of the main region along its width direction; the proportion of anti-deformation yarns in the main region is less than the proportion of anti-deformation yarns in the edge regions; and the twill weave directions of the main region and the edge regions are opposite.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the width of the edge area on one side of the main body area is 1 / 5 to 1 / 3 of the total width of the webbing.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the weaving pattern of the main body area and the edge area is left twill weave or right twill weave.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the angle of the twill weave is 30°~60°.

[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the anti-deformation yarn is polyester industrial yarn or aramid yarn.

[0009] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the weaving pattern of twill weave is two up and one down or three up and one down.

[0010] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the warp density of the main area is 120~180 threads / 10cm, and the weft density is 80~120 threads / 10cm.

[0011] One embodiment of this utility model solves its technical problem by providing a transition region between the main body region and each edge region. The transition area contains m columns of warp yarns and n rows of weft yarns as one weave cycle, where m and n are both greater than or equal to 3. Within the weave cycle of the transition area, the distribution of warp weave points forms at least two continuous weave point columns that are inclined in different directions. The inclination direction of the continuous weave point columns corresponds to the twill direction of the main area and the edge area, respectively, and at least two continuous weave point columns intersect within the transition area.

[0012] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the main body area adopts right-hand diagonal weave, and the weave pattern of the main body area is up-down-up; the edge area adopts left-hand diagonal weave, and the weave pattern of the edge area is down-down-up; m and n are both 3.

[0013] A garment includes a garment body and an anti-deformation webbing, the anti-deformation webbing being disposed at the waist of the garment body.

[0014] The beneficial effects of this utility model are: The main warp and weft yarns in the main area are still conventional textile yarns, which account for a larger proportion. These conventional yarns, such as nylon and polyester filaments, usually have moderate modulus, good elongation and softness, thus ensuring that the main body of the webbing can produce the necessary elastic deformation rather than rigid resistance when subjected to bending or complex deformation, maintaining the flexible feel and applicability of the webbing base.

[0015] The use of opposite twill directions in the main and edge areas results in a more balanced stress distribution within the webbing, improving overall structural stability. The edge areas bear more tensile and frictional loads, and the higher proportion of deformation-resistant yarns significantly enhances dimensional stability and abrasion resistance in this region. The opposing twill weave structure generates mutually restraining moments when the webbing is subjected to transverse stress, effectively resisting curling, torsional deformation, and stress concentration. Through edge reinforcement and interlocking with the weave structure, the webbing is less prone to creep, loosening, or wrinkling under long-term dynamic loads or harsh environments.

[0021] Reference Figure 1 This application proposes an embodiment of the anti-deformation webbing, which includes: a webbing body, the webbing body being woven with warp and weft yarns to form a twill weave, wherein the warp and weft yarns are respectively composed of textile yarns and anti-deformation yarns; the webbing body includes a main region 10 and edge regions 20 disposed on both sides of the main region 10 along its width direction; the density of the anti-deformation yarns in the main region 10 is less than the density of the anti-deformation yarns in the edge regions 20; and the twill weave directions of the main region 10 and the edge regions 20 are opposite.

[0022] In this embodiment, both the warp and weft yarns of the webbing are made of ordinary nylon yarn and high-modulus polyester industrial yarn, i.e., anti-deformation yarn, twisted or woven together. The main body area 10 of the webbing is woven with a two-up-one-down right-hand twill weave. Along the width direction of the webbing, the portion accounting for 60% of its total width is defined as the main body area 10, and the portions on both sides, each accounting for approximately 20% of the width, are defined as the edge areas 20.

[0023] The warp and weft yarns of the main area 10 are both made of a blended yarn consisting of 70% nylon and 30% 1000dtex high-modulus polyester industrial yarn twisted together. The warp and weft yarns of the edge area 20 are made of a blended yarn consisting of 50% nylon and 50% polyester industrial yarn of the same specification twisted together.

[0024] The use of opposite twill directions in the main body region 10 and the edge region 20 results in a more balanced stress distribution within the webbing, improving overall structural stability. The edge region 20 bears more tensile and frictional loads, and the higher proportion of deformation-resistant yarns significantly enhances its dimensional stability and abrasion resistance. The opposite twill direction structure, when the webbing is subjected to lateral stress causing it to curl in one direction, generates opposing restoring moments in the two regions, creating mutually restraining moments that effectively resist curling, torsional deformation, and stress concentration. Through edge reinforcement and interlocking with the weave structure, the webbing is less prone to creep, loosening, or wrinkling under long-term dynamic loads or harsh environments.

[0025] The width of the edge region 20 on one side of the main body region 10 is 1 / 5 to 1 / 3 of the total width of the webbing. For a webbing with a total width of 50mm, the width of the edge region 20 on one side is designed to be 10mm. This width range ensures that the edge region 20 has sufficient volume to bear the main stress, while avoiding excessive stiffness and reduced flexibility of the webbing due to an excessively wide edge, or insufficient reinforcement effect due to an excessively narrow edge.

[0026] In this embodiment, the main body area 10 is woven with a right-hand twill weave, and the edge area 20 is woven with a left-hand twill weave. Left / right twill weaves are mature woven structures that create clear diagonal patterns by controlling the interlacing pattern of the warp and weft yarns. The twill weave uses a two-up-one-down or three-up-one-down weave pattern, which is a common float length for twill weaves, balancing density and flexibility.

[0027] The twill angle of twill weave is between 30° and 60°, which can balance the need for a significant twill effect and a tight structure.

[0028] The anti-deformation yarn is either polyester industrial yarn or aramid yarn. In this embodiment, the anti-deformation yarn is high-modulus polyester industrial yarn with a breaking strength greater than 7 cN / dtex and a dry heat shrinkage rate of less than 5%. Both polyester industrial yarn and aramid yarn have the characteristics of high modulus, low creep, and fatigue resistance, which can effectively suppress the stretching and rebound deformation of the yarn itself, thereby giving the webbing overall anti-deformation performance.

[0029] In this embodiment, the warp density of the main body area 10 is 120-180 yarns / 10cm, and the weft density is 80-120 yarns / 10cm. This density range matches the twill weave of two-up-one-down or three-up-one-down, ensuring the tightness of the webbing structure. It is neither too dense and stiff, nor too sparse and affects the strength and appearance.

[0030] Preferably, a transition region 30 is provided between the main body region 10 and each edge region 20; The transition region 30 contains m columns of warp yarns and n rows of weft yarns as one weave cycle, where m and n are both greater than or equal to 3. Within the weave cycle of the transition region 30, the distribution of warp weave points forms at least two continuous weave point columns that are inclined in different directions. The inclination directions of the continuous weave point columns correspond to the twill direction of the main body region 10 and the edge region 20, respectively, and at least two continuous weave point columns intersect within the transition region 30.

[0031] Warp stitches are designed in the transition region 30 between the main body region 10 and the edge region 20. Continuous warp stitches in the transition region 30 form a clear diagonal weave on the fabric surface. This diagonal line constitutes a load transfer path. At least two consecutive stitches inclined in different directions simultaneously introduce the diagonal force flow of the main body region 10 and the load of the edge region 20 into the transition region 30. When the webbing is under load, the internal stress will be transferred along this continuous torsional path, rather than forming a stress peak at the originally abrupt boundary line. This eliminates the stress concentration perpendicular to the webbing direction caused by the direct splicing of the diagonal weave between the main body and the edge region 20, thus improving the fatigue life of the webbing under repeated tensile and bending loads.

[0032] By ensuring that each row has at least two warp points, and that these two warp points are staggered in a stepped manner between adjacent rows, a "broken twill" weave is essentially created by using multiple weft points per row and forcing them to stagger between rows. This breaks the direction of the continuous twill, causing the twill lines to smoothly change direction in the transition area 30. This design avoids the abrupt jump in the weave structure from right to left twill, causing the stress transmission path within the weave to change gradually, thereby eliminating stress concentration at the abrupt interface.

[0033] See attached document Figure 1 As shown in the figure, the horizontal direction in Figure 1 is the weft direction and the vertical direction is the warp direction. In this embodiment, the main body region 10 uses a right-hand twill weave with an up-down-up weave pattern, and the edge region 20 uses a left-hand twill weave with a down-down-up weave pattern. Both m and n are 3. Preferably, the width of each transition region 30 is less than or equal to 1 / 10 of the total width of the webbing. For a webbing with a total width of 50mm, the total width of the transition regions 30 is designed to be 4mm, distributed between the main body and the two side edges. The transition regions 30 need to be wide enough to achieve effective stress gradient, but not too wide to avoid becoming the main load-bearing area or affecting the overall performance design of the webbing. While ensuring the transition function, the impact of the transition regions 30 on the mechanical properties and weight of the webbing main body is minimized.

[0034] This application also proposes a garment comprising a garment body and an anti-deformation webbing, wherein the anti-deformation webbing is disposed at the waist of the garment body. The garment types include underwear, cropped pants, thermal pants, and other close-fitting trousers. Applying the aforementioned anti-deformation webbing to close-fitting trousers improves the anti-deformation and wrinkle-resistant properties of the waistband, while ensuring that the waistband effectively resists the curling, torsional deformation, and stress concentration of the webbing, thus guaranteeing a comfortable, close-fitting fit.

Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
