Description

Technical Field

[0001] This utility model relates to the field of woven fabric technology, specifically to a striped woven fabric. Background Technology

[0002] Stripes, as a classic visual element, are widely used in textile design, especially in footwear, bags, clothing, and home furnishings. Striped woven fabrics are favored for their aesthetic appeal and design diversity. However, with the upgrading of the consumer market, users have increasingly higher demands for products, no longer satisfied with a single visual appearance, but placing higher comprehensive requirements on durability, shape retention, texture, and functionality. Currently, striped woven fabrics suffer from drawbacks such as low structural strength and poor dimensional stability. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the background art and to provide a striped woven fabric that can improve the defects of low structural strength and poor dimensional stability of existing striped woven fabrics.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Technical Solution 1: A striped woven fabric, which is woven from warp yarns, a first weft yarn, and a second weft yarn; the warp yarn is a polyamide twisted yarn with a breaking strength of not less than 6.0 cN / dtex; the first weft yarn is a twisted yarn containing a polyester polymer component; the second weft yarn is a twisted yarn containing a polyester polymer component, and the linear density of the second weft yarn is more than 1.5 times that of the linear density of the first weft yarn; the warp yarns, the first weft yarn, and the second weft yarn are interwoven in a twill weave, and the first weft yarn and the second weft yarn are arranged in a predetermined pattern.

[0006] Technical Solution 2 based on Technical Solution 1: The first weft yarn is a core-spun yarn with polyurethane fiber as the core and polyester polymer fiber as the outer layer.

[0007] Technical Solution 3 based on Technical Solution 2: The second weft yarn is a plied yarn, which is made by twisting together monofilaments of polyamide polymer and monofilaments of polyester polymer.

[0008] Technical Solution 4 based on Technical Solution 3: The linear density of the first weft yarn is 100-300D and the twist is 200-450 twists / meter; the linear density of the second weft yarn is 450-1200D and the twist is 100-300 twists / meter.

[0009] Technical solution five based on technical solution four: The preset pattern is that one first weft yarn and one second weft yarn are arranged alternately, and the twill weave is a 2 / 2 twill weave.

[0010] Technical solution six based on technical solution five: the linear density of the warp yarn is 150-300D, and the twist is 300-500 twists / meter.

[0011] Technical solution seven based on technical solution six: the warp yarn has a Z-twist, and the first weft yarn and the second weft yarn both have an S-twist.

[0012] Technical solution eight, based on technical solution seven: the unit area weight of the fabric is 200-350 grams per square meter.

[0013] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0014] Technical Solution 1 organically combines specific high-performance warp yarns, two weft yarns with clearly defined functional divisions, and a specific fabric structure to obtain a striped woven fabric that combines high structural strength, high dimensional stability, and a clear three-dimensional striped appearance. Existing striped woven fabrics suffer from an inherent contradiction between structural performance and striped appearance. This is because: on the one hand, the high-density weaving structure used to achieve high strength greatly restricts the physical space of the yarns, thus inhibiting the formation of three-dimensional stripes; on the other hand, combining high-performance industrial fibers (such as high-strength polyamide) with ordinary decorative fibers (such as polyester) with vastly different physical properties presents significant processing challenges.

[0015] Therefore, the warp yarns of the striped woven fabric in this technical solution use polyamide twisted yarns with a breaking strength of not less than 6.0 cN / dtex. The high breaking strength inherent in polyamide high-strength fibers provides a solid mechanical foundation for the warp (longitudinal) direction of the fabric, which is the fundamental guarantee against external tensile forces and to prevent the fabric from tearing. Simultaneously, the warp yarns are twisted, using physical action to make the fibers more tightly bound together. This not only further improves the breaking strength of the yarn, but more importantly, it significantly reduces the breaking elongation of the yarn. Based on this, both weft yarns also use twisted yarns. This design ensures that the fabric also has high strength and low elongation in the weft (transverse) direction. When the high-strength, low-elongation warp yarns interweave with the low-elongation weft yarns, they together form a two-dimensional mesh structure with high stability in both the warp and weft directions. Therefore, when the fabric is subjected to external forces, this structure can effectively resist deformation, thereby ensuring the overall dimensional stability of the fabric and solving the fundamental defect of existing striped fabrics that are prone to stretching and deformation due to insufficient skeleton strength.

[0016] Furthermore, this striped woven fabric employs two weft yarns with significantly different linear densities (the second weft yarn has a linear density more than 1.5 times that of the first weft yarn). The coarser weft yarn (the second weft yarn), occupying a larger physical space in the fabric, naturally creates a raised effect on the fabric surface. These two weft yarns are interwoven with the warp yarns in a twill weave. The structural characteristic of a twill weave is that its warp and weft interlacing points are sparser than in a plain weave, resulting in longer floats on the fabric surface. This structural feature provides sufficient space for the coarser second weft yarn to float, allowing it to be unconstrained by excessive interlacing points, thus maximizing its prominence on the fabric surface and forming a full, continuous physical protrusion—a three-dimensional stripe. Simultaneously, the first and second weft yarns are arranged in a predetermined cyclical pattern, ensuring that the raised stripes formed by the coarse weft yarn and the recessed areas formed by the fine weft yarn create a regular and clear visual and tactile contrast, thus forming a striped pattern with well-defined boundaries. Most importantly, the application of the twill weave in this design plays a dual and mutually reinforcing role. On the one hand, as mentioned above, it greatly enhances the three-dimensionality of the stripes formed by the coarse weft yarn by providing long floats; on the other hand, its sparse interlacing points reduce excessive bending and friction on the high-performance warp yarns compared to plain weave, better maintaining the intrinsic strength of the high-strength polyamide fiber and contributing to the realization of the overall mechanical properties of the fabric.

[0017] In technical solution two, by replacing the first weft yarn with a core-spun yarn consisting of polyurethane fibers as the core and an outer layer of polyester polymer fibers, a controllable elastic recovery function is introduced into the fabric, thus solving the problem of insufficient dynamic comfort commonly found in high-strength, high-stability fabrics. The polyurethane core has high elongation and excellent elastic recovery characteristics. When the fabric is bent under stress, the first weft yarns, located in the concave areas of the fabric structure, primarily elongate to provide cushioning. After the external force is removed, the recovery force of the polyurethane allows the fabric to quickly return to its original shape. More importantly, this elasticity is localized and controlled. The overall dimensional stability of the fabric is still ensured by the high-strength polyamide warp yarns and the second weft yarns, which provide rigid support. Therefore, by embedding flexible functional areas within a stable structure, the fabric maintains macroscopic stability and shape retention while possessing comfortable elasticity that adapts to dynamic activities at the microscopic level, achieving a balance between these two contradictory properties.

[0018] In technical solution three, by replacing the second weft yarn with a ply yarn composed of polyamide polymer filaments and polyester polymer filaments, the surface abrasion resistance of the fabric is significantly improved, solving the problem of easy wear on the raised parts of the fabric. The abrasion resistance of polyester fibers is far lower than that of polyamide fibers. When the fabric is repeatedly scratched, these raised polyester stripes will wear out before other parts of the fabric, affecting the long-term service life and appearance of the fabric. In this solution, by plying highly abrasion-resistant polyamide filaments into the second weft yarn, it is given stronger protective capabilities. The presence of the polyamide component greatly improves the abrasion resistance of the raised stripes.

[0019] Technical Solution Four specifies the linear density and twist parameters of the two weft yarns mentioned above. The linear density range of the first weft yarn (100-300D) ensures that it provides elasticity without being too weak, and can withstand the tension during weaving and use. The linear density range of the second weft yarn (450-1200D) ensures a sufficiently large physical volume difference between it and the first weft yarn, thus forming a clear and perceptible three-dimensional striped effect. The selection of the two weft yarn twist ranges ensures yarn strength and cohesion while avoiding yarn stiffness and a rough hand feel caused by excessive twisting.

[0020] Technical Solution Five specifies the arrangement of the weft yarns and the specific form of the twill weave. Using an alternating pattern of one first weft yarn and one second weft yarn clearly and evenly showcases the difference between the two functional weft yarns, resulting in uniform stripe spacing and a stable visual effect. The 2 / 2 twill weave is a preferred specific form of twill weave. This weave provides sufficient float length to ensure the fullness and prominence of the second weft yarn, while its interlacing density is denser than higher-order twill weaves such as 3 / 3. This ensures both three-dimensionality and fabric softness while also providing better structural stability and dimensional control.

[0021] Technical Solution Six specifies the linear density and twist of the warp yarns. A linear density range of 150-300D provides sufficient warp strength to withstand the tension differences generated during weaving of two different weft yarns, ensuring the structural strength of the final product. A twist range of 300-500 twists / meter provides stability while also ensuring a certain degree of flexibility in the warp yarns, preventing the entire fabric from becoming too stiff.

[0022] Technical Solution Seven specifies the twist direction of the warp and weft yarns. In a fabric structure, the twist direction of the yarns generates a potential torsional moment. By employing an opposite twist configuration—Z-twist for warp yarns and S-twist for weft yarns—the internal torsional moments of the warp and weft yarns cancel each other out after interlacing. This force balance ensures that the fabric structure itself is free of internal stress, preventing the fabric from twisting or skewing after wet heat treatments such as washing and heat setting, thus guaranteeing the flatness and squareness of the finished fabric surface.

[0023] Technical Solution 8 specifies the unit area weight of the finished fabric. Fabrics within this weight range have moderate thickness and quality, reflecting both solid materials and tight structure, without being too heavy, meeting the requirements for durability and texture in fields such as footwear and bags.

[0035] Example

[0036] This embodiment relates to a striped woven fabric, as shown in the reference... Figure 1 The striped woven fabric is woven from warp yarn 1, first weft yarn 2, and second weft yarn 3. The warp yarn 1 is a polyamide twisted yarn with a breaking strength of not less than 6.0 cN / dtex. The first weft yarn 2 is a twisted yarn containing polyester polymer components. The second weft yarn 3 is a twisted yarn containing polyester polymer components, and the linear density of the second weft yarn 3 is more than 1.5 times that of the linear density of the first weft yarn 2. The warp yarn 1, the first weft yarn 2, and the second weft yarn 3 are interwoven in a twill weave, and the first weft yarn 2 and the second weft yarn 3 are arranged in a cyclic pattern according to a preset rule.

[0037] Specifically, the finished striped woven fabric exhibits, in its macroscopic structure, continuous stripes extending along the transverse (weft) direction of the fabric, possessing a physical convex-concave morphology. Looking at the cross-sectional structure of the fabric, the second weft yarn 3, with its higher linear density, forces the warp yarn 1 to shift significantly on its upper and lower sides when interlacing with it, thus forming a physically raised area on the fabric surface—the convexity of the stripe. The adjacent first weft yarn 2, with its lower linear density, has less impact on the displacement of the warp yarn 1 when interlacing with it, forming a relatively flat or concave area—the concave area of ​​the stripe. This alternating arrangement of ridges and valleys, formed by the combined effect of differences in yarn physical volume and the interlacing structure, constitutes the three-dimensional stripes of the fabric. Manufacturing can be carried out on conventional weaving equipment such as air-jet looms, water-jet looms, or rapier looms. The treated warp yarn 1 is wound orderly onto the warp beam, and the first weft yarn 2 and the second weft yarn 3 are prepared as two independent weft yarn sources. During the weaving process, the warp yarns 1 and weft yarns are interwoven into fabric through a series of actions such as shedding, weft insertion, beating, and take-up on the loom. The weft insertion action, according to a preset pattern, alternately introduces either the first weft yarn 2 or the second weft yarn 3 from two weft yarn sources. The preset pattern can be an alternation between one first weft yarn 2 and one second weft yarn 3, or an alternation between two first weft yarns 2 and two second weft yarns 3, etc.

[0038] Among them, reference Figure 2 The first weft yarn 2 is a core-spun yarn with a polyurethane fiber core 4 and an outer layer of polyester polymer fibers. Specifically, the first weft yarn 2 is a composite yarn structure. Its central axial portion is the core 4, composed of one or more polyurethane elastic filaments. The outer layer of the core 4 is a sheath 5 composed of polyester polymer fibers. In cross-section, the core 4 is located at the center, and the sheath 5 fibers are evenly distributed around the core 4, completely enveloping it. During manufacturing, the polyurethane core 4 is continuously fed in under a certain stretch, while the outer polyester staple fibers or filaments are spirally and tightly wound around the stretched core 4 surface through twisting. When the finished yarn tension is released, the shrinkage force of the core 4 causes the outer sheath 5 fibers to produce slight, irregular bends, giving the yarn additional bulk and potential elongation. This structure allows the first weft yarn 2 to appear as polyester fiber in terms of appearance and dyeing properties, but exhibits the elastic recovery characteristics provided by the inner core 4 when under stress.

[0039] Reference Figure 3The second weft yarn 3 is a plied yarn, formed by twisting together monofilaments of a polyamide polymer and a polyester polymer. Specifically, this second weft yarn 3 is also a composite yarn structure, formed by combining and twisting at least two different monofilaments. Its internal structure consists of a polyamide polymer filament and a polyester polymer filament spirally intertwined along a common axis. From the yarn cross-section, two or more independent circular or irregularly shaped filament sections can be seen tightly compressed together. During manufacturing, these two raw material filaments are unwound from their respective bobbins and combined into one strand, then twisted using a twisting machine. The physical force of twisting causes the two filaments to tightly bind together, forming a single yarn. In this structure, the polyamide filament and polyester filament coexist continuously along the yarn length, allowing any segment of the yarn to simultaneously possess the physical properties of both materials.

[0040] Furthermore, the linear density of the first weft yarn 2 is 100-300D, and the twist is 200-450 twists / meter; the linear density of the second weft yarn 3 is 450-1200D, and the twist is 100-300 twists / meter. Specifically, when selecting yarns, the linear density of the first weft yarn 2 can be selected within the range of 100-300D. For example, 150D or 250D polyester / spandex core-spun yarn can be selected, and a twist within the range of 200-450 twists / meter can be applied to it, such as 300 twists / meter. The linear density of the second weft yarn 3 is selected within the range of 450-1200D. For example, 600D or 900D polyamide / polyester ply yarn can be selected, and a twist within the range of 100-300 twists / meter can be applied to it, such as 150 twists / meter. In this design, a 150D first weft yarn (2) and a 600D second weft yarn (3) can be used. The linear density of the second weft yarn (3) is four times that of the first weft yarn (2). This significant difference in physical volume forms the structural basis for clear, three-dimensional stripes. Simultaneously, applying a relatively high twist (e.g., 300 twists / meter) to the first weft yarn (2) ensures sufficient strength and density to withstand weaving tension even at a finer yarn. Applying a relatively low twist (e.g., 150 twists / meter) to the second weft yarn (3) maximizes the yarn's bulk and volume while maintaining a stable ply structure, preventing excessive twisting from causing the yarn to become too thin and stiff, thus affecting the final three-dimensional effect.

[0041] The warp yarn 1 has a linear density of 150-300D and a twist of 300-500 twists / meter. The warp yarn 1 acts as the longitudinal skeleton in the fabric, and its structural parameters must match the weft yarn system. Selecting a warp yarn 1 within this range, such as 210D, ensures that its physical diameter and strength are sufficient to withstand the enormous machine tension without breaking when weaving high-density structures. Simultaneously, it also needs sufficient stiffness to effectively bind the thicker second weft yarn 3 to the predetermined fabric position during interlacing, forming stable interlacing points without being excessively compressed or displaced by the weft yarn, thus ensuring the integrity and squareness of the entire fabric structure.

[0042] A twist of 300-500 twists per meter provides excellent fatigue resistance and abrasion resistance for warp yarn 1.

[0043] The preset pattern is that a first weft yarn 2 and a second weft yarn 3 are arranged alternately, and the twill weave is a 2 / 2 twill weave. Specifically, the specific geometric shape of the fabric structure is as follows: the movement trajectory of each warp yarn 1 is to continuously cross over two weft yarns and then continuously pass under the next two weft yarns. For example, when a warp yarn 1 interweaves with the first, second, third, and fourth weft yarns, its path may be floating above the first and second weft yarns and then sinking under the third and fourth weft yarns. Since the weft yarns are arranged in the order of a first weft yarn 2 (fine) and a second weft yarn 3 (coarse), the above-mentioned warp yarn 1 path is specifically manifested as: floating above the fine and coarse weft yarns and then sinking under the next set of fine and coarse weft yarns. When the second weft yarn 3 (coarse weft yarn) is in a position crossed by the warp yarn 1 (i.e., the warp float), its convex effect is suppressed by the warp yarn 1; while when it is in a position crossing the warp yarn 1 (i.e., the weft float), its convex effect is completely released. The longer weft float segments provided by the 2 / 2 twill weave are structurally guaranteed to form full stripes. During weaving, settings are made on the loom's control system to ensure that the loom's weft selection device (e.g., an electronic weft selector) strictly follows the sequence of one first weft yarn 2 followed by one second weft yarn 3 in each weft insertion cycle. Simultaneously, the loom's jacquard head or electronic heald lift device is controlled to cause the warp heald frame to move up and down in a two-up-two-down pattern.

[0044] Furthermore, the warp yarn 1 has a Z-twist, while the first weft yarn 2 and the second weft yarn 3 both have an S-twist. Specifically, a single yarn itself has a torsional internal stress due to twisting, which tends to cause the yarn to rotate in the opposite direction. In the fabric, the warp yarn 1 and the weft yarn interweave at an angle close to 90 degrees. When the Z-twist warp yarn 1 and the S-twist weft yarn combine at the interlacing point, the torque of the warp yarn 1 attempting to rotate in the opposite direction (S-direction) is exactly opposite to the torque of the weft yarn attempting to rotate in the opposite direction (Z-direction). These two opposing torques cancel each other out at the interlacing point, making the interlacing point a structurally stable node without a net twisting tendency. In the yarn twisting process, different twist directions are achieved by setting the rotation direction of the spindle or turntable of the twisting equipment (e.g., a doubling twister or a twisting machine). To obtain Z-twist yarn, the equipment is set so that the direction of the spiral formed by the yarn during twisting is consistent with the tilt direction of the middle part of the letter "Z". To obtain S-twist yarn, the equipment is configured so that the spiral direction of the yarn is aligned with the tilt direction of the middle part of the letter "S". In producing the fabric of this embodiment, all warp yarns 1 are Z-twist, and all first weft yarns 2 and second weft yarns 3 are S-twist. This warp and weft reverse twist configuration allows the internal torsional moments of the fabric to cancel each other out after interlacing, ensuring the smoothness of the fabric structure and the stability of its dimensions.

[0045] Finally, the resulting fabric has a basis weight of 200-350 g / m². Specifically, the basis weight is determined by the linear density of the warp and weft yarns, the warp and weft density set during weaving, and the shrinkage rate during finishing. Before weaving, appropriate warp yarn arrangement density (e.g., number of yarns per centimeter) and weft yarn density (e.g., number of yarns per centimeter) are calculated and set. After weaving, the fabric undergoes heat setting on a tenter frame. By precisely controlling the temperature, machine speed, and fabric width during setting, the fabric achieves the desired shrinkage. Through coordinated control of all the above parameters, the basis weight of the finished fabric is ultimately controlled within the range of 200-350 g / m², for example, approximately 280 g / m². The heat setting temperature range for this striped woven fabric is 160°C to 180°C, preferably 170°C.

[0046] The warp yarn 1 of the striped woven fabric involved in this embodiment uses polyamide twisted yarn with a breaking strength of not less than 6.0 cN / dtex. The high breaking strength of polyamide high-strength fibers provides a solid mechanical foundation for the warp (longitudinal) direction of the fabric, which is the fundamental guarantee for resisting external tensile forces and preventing the fabric from being torn. At the same time, the warp yarn 1 is twisted, and the fibers are more tightly bound together by physical action. This not only further improves the breaking strength of the yarn, but more importantly, it can significantly reduce the breaking elongation of the yarn. On this basis, both weft yarns also use twisted yarn. This design ensures that the weft (transverse) direction of the fabric also has high strength and low elongation. When the high-strength, low-elongation warp yarn 1 is interwoven with the low-elongation weft yarn, they together form a two-dimensional mesh structure with high stability in both the warp and weft directions. Therefore, when the fabric is subjected to external forces, this structure can effectively resist deformation, thereby ensuring the overall dimensional stability of the fabric and solving the fundamental defect of existing striped fabrics that are prone to stretching and deformation due to insufficient skeleton strength.

[0047] Furthermore, this striped woven fabric employs two weft yarns with significantly different linear densities (the second weft yarn 3 has a linear density more than 1.5 times that of the first weft yarn 2). The coarser weft yarn (second weft yarn 3), occupying a larger physical space in the fabric, naturally creates a raised effect on the fabric surface. These two weft yarns are interwoven with the warp yarn 1 in a twill weave. The structural characteristic of a twill weave is that its warp and weft interlacing points are sparser than in a plain weave, resulting in longer floats on the fabric surface. This structural feature provides sufficient space for the coarser second weft yarn 3 to float, allowing it to be unconstrained by excessive interlacing points and thus maximize its prominence on the fabric surface, forming a full, continuous physical protrusion—a three-dimensional stripe. Simultaneously, the first weft yarn 2 and the second weft yarn 3 are arranged cyclically according to a predetermined pattern. This ensures that the raised stripes formed by the coarse weft yarn and the recessed areas formed by the fine weft yarn create a regular and clear visual and tactile contrast, thus forming a striped pattern with well-defined boundaries. Most importantly, the application of the twill weave in this design plays a dual and mutually reinforcing role. On the one hand, as mentioned above, it greatly enhances the three-dimensionality of the stripes formed by the coarse weft yarn by providing long floating threads; on the other hand, its sparse interlacing points reduce excessive bending and friction on the high-performance warp yarn 1 compared to plain weave, better maintaining the intrinsic strength of the high-strength polyamide fiber and contributing to the realization of the overall mechanical properties of the fabric.

[0048] Therefore, the striped woven fabric involved in this embodiment organically combines specific high-performance warp yarns 1, two weft yarns with clearly defined functions, and specific fabric structure to obtain a striped woven fabric that has both high structural strength, high dimensional stability, and a clear three-dimensional striped appearance.

Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
