Fabric and method for processing the same

Abstract

This application discloses a fabric and its processing method. The fabric processing method includes the following steps: configuring a first yarn group and a second yarn group, wherein the first yarn group includes a base yarn and reinforcing yarns spaced apart within the base yarn, and the second yarn group includes a base yarn, wherein the tensile strength of the reinforcing yarns is greater than that of the base yarns; and interlacing the first yarn group and the second yarn group to obtain the fabric. This application utilizes the high breaking strength of the reinforcing yarns, which have higher tensile strength, to prevent crack propagation by distributing reinforcing yarns at intervals within the base yarns. Furthermore, since the reinforcing yarns are only locally distributed, the overall elasticity and lightweight of the fabric are not significantly affected.

Description

Technical Field

[0001] This application relates to the field of apparel technology, and in particular to a fabric and its processing method. Background Technology

[0002] Elastic fabrics are widely used in sportswear, especially in tight-fitting garments for running, cross-training, and yoga, where high demands are placed on the fabric's elastic recovery and lightweight breathability. Currently, the industry generally uses elastic-covered yarns for weaving, with spandex as the core yarn to provide elasticity and nylon or other synthetic fibers as the outer layer to provide strength and abrasion resistance. The combination of these two materials forms a base fabric that balances elasticity and hand feel.

[0003] However, these elastic fabrics suffer from insufficient tear resistance during actual wear. Because the fabric aims for lightness and breathability, it typically uses lower warp and weft density and finer yarn specifications, resulting in larger gaps between the yarns. When the fabric is snagged by a sharp object or experiences localized stress concentration, cracks can easily propagate rapidly along these yarn gaps, leading to fabric damage.

[0004] In existing technologies, there are two main approaches to improving the tear resistance of fabrics. One approach involves using higher-strength fibers during the weaving process, such as high-molecular-weight polyethylene fibers and aramid fibers, utilizing their high tensile strength to resist tearing. The other approach is to increase the overall warp and weft density of the fabric, thereby improving the overall strength of the fabric by increasing the tightness of the yarn arrangement. However, introducing high-strength fibers usually leads to a decrease in fabric elasticity because these fibers have a high elastic modulus and low elongation, which restricts the normal tensile recovery of elastic yarns; while increasing the overall warp and weft density leads to an increase in fabric weight and a decrease in breathability, making it difficult to meet the lightweight requirements of sports fabrics. Summary of the Invention

[0005] One objective of this application is to provide a fabric and a processing method thereof, which aims to solve the technical problem that it is difficult to achieve both lightweight and elastic properties and tear resistance in sportswear fabrics.

[0006] To achieve the above objectives, in a first aspect, this application provides a fabric processing method, comprising the following steps: configuring a first yarn group and a second yarn group, wherein the first yarn group includes a base yarn and reinforcing yarns spaced apart in the base yarn, and the second yarn group includes a base yarn, wherein the tensile strength of the reinforcing yarn is greater than the tensile strength of the base yarn; and interlacing the first yarn group and the second yarn group to obtain a fabric.

[0007] In the above processing method, the reinforcing yarns are spaced apart within the base yarns of the first yarn group and interwoven with the second yarn group, forming locally high-strength nodes with spaced distribution in the fabric. When the fabric is subjected to localized stress concentration or snagging, causing cracks, the cracks propagate along the gaps between the base yarns. When they reach the location of the reinforcing yarns, because the tensile strength of the reinforcing yarns is greater than that of the base yarns, the cracks require more energy to break, thus effectively blocking the further propagation of the cracks and preventing them from penetrating the entire fabric.

[0008] Meanwhile, because the reinforcing yarns are only interspersed among the base yarns rather than replacing them entirely, most areas of the fabric still consist of base yarns with lower tensile strength. These base yarn areas maintain good elastic recovery and low areal density. Therefore, the above processing method improves the fabric's tear resistance while maintaining its overall elasticity and lightweight, meeting the performance requirements of sportswear.

[0009] Furthermore, in the aforementioned processing method, the reinforcing yarn is not introduced into the fabric through finishing or additional processes after interlacing. Instead, it is distributed intermittently among the base yarns during the configuration of the first yarn group, allowing the reinforcing yarn to interlac with the second yarn group as a component of the first yarn group. Because the reinforcing yarn is incorporated into the fabric structure during the interlacing stage, a tight mechanical interlocking relationship is formed between the reinforcing yarn, the adjacent base yarn, and the second yarn group through warp and weft interlacing. The reinforcing yarn is firmly anchored within the fabric structure, reducing the potential interface debonding or peeling problems that may occur with subsequent incorporation processes.

[0010] In conjunction with the first aspect, according to one embodiment of this application, both the base yarn and the reinforcing yarn are covered yarns, and the method further includes: stretching the core yarn; while the core yarn is in a stretched state, spirally wrapping the covering yarn along the outer periphery of the core yarn to obtain covered yarn.

[0011] In this embodiment, the core yarn is first stretched to store elastic potential energy under tension. Then, while the core yarn remains stretched, the covering yarn is spirally wrapped around its outer circumference, forming a tight spiral winding structure with the core yarn even when it is stretched. When the core yarn retracts after wrapping, its radial expansion further tightens the spiral wrapping layer, making the wrapping structure more compact and stable. This preparation method results in a covered yarn with high structural density and elastic recovery force even in its natural state, which is beneficial for the fabric to achieve good elastic recovery performance after interweaving.

[0012] In conjunction with the first aspect, according to one embodiment of this application, the core yarn is spandex and the sheath yarn is nylon.

[0013] In conjunction with the first aspect, according to one embodiment of this application, when the wrapping filament is spirally wrapped around the outer periphery of the core filament, the wrapping twist is 1000 to 1200 twists / meter; and / or, when the core filament is drawn, the draw ratio of the core filament is 3.5 to 3.8 times.

[0014] In conjunction with the first aspect, according to one embodiment of this application, when preparing the base yarn, a first core filament is used as the core filament and a first wrapping filament is used as the wrapping filament; when preparing the reinforcing yarn, a second core filament is used as the core filament and a second wrapping filament is used as the wrapping filament; wherein the fineness of the second core filament is greater than that of the first core filament, and / or the fineness of the second wrapping filament is greater than that of the first wrapping filament.

[0015] In this embodiment, by making the fineness of the second core filament in the reinforcing yarn greater than that of the first core filament in the base yarn, and / or by making the fineness of the second wrapped filament in the reinforcing yarn greater than that of the first wrapped filament in the base yarn, the reinforcing yarn has a larger cross-sectional area at both the core filament level and / or the wrapped filament level, thereby making the overall tensile strength of the reinforcing yarn higher than that of the base yarn. Since the strength difference between the reinforcing yarn and the base yarn comes from the change in fineness of the same material rather than the introduction of heterogeneous fibers, the two maintain consistency in elastic modulus and hand feel characteristics, and will not cause local abrupt changes in fabric rigidity or uneven elastic recovery due to material differences.

[0016] In conjunction with the first aspect, according to one embodiment of this application, the fineness of the first core filament is 15D to 30D, the fineness of the first wrapped filament is 30D to 50D, the fineness of the second core filament is 30D to 50D, and the fineness of the second wrapped filament is 60D to 90D.

[0017] In conjunction with the first aspect, according to one embodiment of this application, when the first yarn group and the second yarn group are interwoven, the second yarn group is set first, and then the base yarn and reinforcing yarn of the first yarn group are alternately introduced in a predetermined order during the interweaving process, so that the base yarn and reinforcing yarn of the first yarn group are interwoven in the warp yarn at intervals.

[0018] When the first yarn group is a weft yarn, the spacing of the reinforcing yarn is achieved by alternately introducing the base yarn and the reinforcing yarn in a predetermined order during the weaving process. This method uses the weft feeder or weft selector of the loom to control the sequence, without requiring special adjustments to the warp warping and reed threading processes. The spacing of the reinforcing yarn can be completed simply by switching the yarns at the weft insertion stage. The process is simple to implement and is suitable for conventional weaving equipment such as air-jet looms.

[0019] In conjunction with the first aspect, according to one embodiment of this application, when the first yarn group and the second yarn group are interwoven, the base yarn and the reinforcing yarn of the first yarn group are alternately warped and reed, so that the base yarn and the reinforcing yarn of the first yarn group are spaced apart, and then the second yarn group is introduced to interweave with the first yarn group.

[0020] When the first yarn group is warp, the spacing of the reinforcing yarns is achieved by alternating the base yarn and reinforcing yarn according to a predetermined pattern during the warping and reeding stages. This method completes the reinforcing yarn positioning before interlacing, and the warp yarn arrangement is fixed during interlacing, eliminating the need for yarn switching and ensuring unaffected interlacing efficiency. Simultaneously, precise control of warping and reeding ensures the uniformity of the reinforcing yarn spacing and the accuracy of its position within the warp yarns.

[0021] In conjunction with the first aspect, according to one embodiment of this application, the second yarn group is composed entirely of base yarn; or, the second yarn group includes base yarn and reinforcing yarn, and in the second yarn group, the reinforcing yarn is distributed intermittently among the base yarn.

[0022] In conjunction with the first aspect, according to one embodiment of this application, in the first yarn group, the total number of reinforcing yarns is less than the total number of base yarns.

[0023] In conjunction with the first aspect, according to one embodiment of this application, in the first yarn group, the ratio of the number of base yarns to the number of reinforcing yarns is 2:1 to 5:1; and / or, in the first yarn group, one reinforcing yarn is distributed at intervals between each adjacent M base yarns, and M is not less than 3.

[0024] In conjunction with the first aspect, according to one embodiment of this application, the base yarn in the first yarn group and the second yarn group are interwoven according to a plain weave pattern; the reinforcing yarn in the first yarn group and the second yarn group are interwoven according to a plain weave pattern, a double plain weave pattern, or a square plain weave pattern.

[0025] In conjunction with the first aspect, according to one embodiment of this application, interweaving a first yarn group and a second yarn group to obtain a fabric includes: interweaving the first yarn group and the second yarn group to form a greige fabric; sequentially performing a pre-setting treatment, a dyeing treatment, and a finishing treatment on the greige fabric; wherein the temperature of the pre-setting treatment is higher than the temperature of the finishing treatment, and the temperature of the dyeing treatment is lower than the temperature of the finishing treatment.

[0026] The above dyeing and finishing process employs segmented temperature settings: high-temperature pre-setting, low-temperature dyeing, and medium-temperature finishing. The pre-setting process uses the highest possible temperature to fully heat-set the core yarns, eliminating internal stress accumulated during weaving and fixing the molecular chain conformation of the core yarns, thus stabilizing the fabric structure. Because the pre-setting temperature is higher than the temperatures of subsequent processes, the core yarns, locked in the pre-setting stage, are less prone to significant thermal shrinkage or deformation during the subsequent lower-temperature dyeing and finishing processes, thereby ensuring the dimensional stability of the fabric throughout the entire dyeing and finishing process. The dyeing process uses the lowest temperature to avoid the loosening of the already-set fabric structure due to humid and hot conditions. The finishing process uses a temperature between these two, allowing the molecular chains of the wrapped yarns to fully rearrange and rebuild intermolecular hydrogen bonds, forming a stable finishing effect. Simultaneously, this temperature does not damage the core yarn structure fixed in the pre-setting stage.

[0027] Through the above-mentioned segmented temperature settings, the high-tightness interlacing structure of the reinforcing yarn area is fixed in the pre-setting stage, and the elasticity of the base yarn area is retained in the finished product setting stage. The fabric can still maintain good dimensional stability and flatness after multiple washes and ironing.

[0028] In conjunction with the first aspect, according to one embodiment of this application, the temperature for the pre-forming treatment is 185–195°C; and / or, the temperature for the dyeing treatment is 95–100°C; and / or, the temperature for the final product setting treatment is 160–170°C.

[0029] Secondly, this application also provides a fabric, which is made based on the fabric processing method of any of the embodiments of the first aspect described above.

[0030] Thirdly, this application also provides a fabric comprising a first yarn group and a second yarn group interwoven with each other, the first yarn group comprising a base yarn and reinforcing yarns spaced apart in the base yarn, and the second yarn group comprising a base yarn; wherein the tensile strength of the reinforcing yarn is greater than the tensile strength of the base yarn.

[0031] The beneficial effects of the second and third aspects mentioned above can be referred to in the first aspect or any possible implementation of the first aspect, and will not be elaborated here. Based on the implementations provided in the above aspects, this application can also be further combined to provide more implementations.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] Elastic fabrics are widely used in sportswear, especially in tight-fitting garments for running, cross-training, and yoga. These garments need to repeatedly stretch and recover with the body's movements during wear, thus requiring high elasticity and resilience from the fabric. Simultaneously, the body's heat dissipation needs are significant during exercise, necessitating good breathability. This requires the fabric to be as lightweight as possible while maintaining elasticity. Currently, the industry commonly uses elastic covered yarn as the base yarn for these fabrics. Elastic covered yarn typically uses spandex filaments as the core yarn to provide elasticity and nylon, polyester, or other synthetic fibers as the outer layer to provide strength and abrasion resistance. The combination creates a yarn that balances elasticity and a comfortable feel. During weaving, to achieve a lightweight and breathable effect, the fabric usually uses lower warp and weft densities and finer yarn specifications, resulting in good drape and a comfortable, close-fitting wearing experience.

[0039] However, the aforementioned fabric structure suffers from insufficient tear resistance in actual wear. Due to the fineness of the yarns and the large gaps between them, when the fabric is snagged or scratched by sharp objects, or when subjected to localized stress concentration during dressing or undressing, the yarns in the fabric are easily broken or pulled out, forming an initial tear. Subsequently, the tear rapidly extends to both sides along the gaps between the yarns, causing the damaged area to expand rapidly, seriously affecting the service life and appearance of the garment.

[0040] In the existing technology, the common solutions to improve the tear resistance of fabrics are mainly of the following two categories.

[0041] The first approach involves introducing high-strength fibers into the fabric. For example, high-performance fibers such as ultra-high molecular weight polyethylene (UHMWPE) and aramid fibers can be used to replace conventional yarns, utilizing their significantly higher breaking strength to resist tearing. However, these high-performance fibers generally have a high elastic modulus and a low elongation at break. When introduced into elastic fabrics, the high-modulus fibers create a rigid constraint on the fabric's normal tensile recovery, resulting in a significant decrease in the overall elastic recovery rate of the fabric. This leads to residual deformation after stretching, creating a loose feel when worn, and failing to meet the core requirement of elastic fit for tight-fitting sportswear.

[0042] The second approach is to increase the overall warp and weft density of the fabric. By increasing the number of yarns per unit area, the yarns are arranged more tightly, thereby improving the overall tear resistance of the fabric. Increased warp and weft density means more yarns are involved in load-bearing; when a crack propagates, more yarns need to break to continue extending, thus improving the fabric's tear strength to some extent. However, increasing the overall warp and weft density directly leads to an increase in the fabric's weight per unit area, making the fabric thicker and reducing breathability and drape. For sports fabrics that prioritize lightweight and breathability, this increase in weight contradicts the product's positioning.

[0043] In summary, how to effectively improve the tear resistance of elastic fabrics while maintaining their original elastic recovery and lightweight breathability is a current technical challenge in the field of sports fabrics.

[0044] To solve the above technical problems, please refer to Figure 1 In a first aspect, this application provides a fabric processing method, comprising the following steps: configuring a first yarn group 1 and a second yarn group 2, wherein the first yarn group 1 includes a base yarn 3 and reinforcing yarns 4 spaced apart in the base yarn 3, and the second yarn group 2 includes the base yarn 3, wherein the tensile strength of the reinforcing yarn 4 is greater than the tensile strength of the base yarn 3; and interlacing the first yarn group 1 and the second yarn group 2 to obtain a fabric.

[0045] It should be understood that the phrase "reinforcing yarn 4 is intermittently distributed among the base yarn 3" in this application refers to the reinforcing yarn 4 being distributed in a non-concentrated manner among the base yarn 3 of the first yarn group 1, rather than all the reinforcing yarn 4 being concentrated in a local area of ​​the first yarn group 1. In other words, "intermittently distributed among the base yarn 3" defines the dispersed and mixed relationship of the reinforcing yarn 4 relative to the base yarn 3, that is, in the yarn arrangement of the first yarn group 1, the reinforcing yarn 4 and the base yarn 3 alternate with each other rather than being clustered in patches or blocks. As for the specific distribution pattern of the reinforcing yarn 4, it includes, but is not limited to: a fixed number of base yarn 3s between two adjacent reinforcing yarns 4, unequal numbers of base yarn 3s between two adjacent reinforcing yarns 4, and the reinforcing yarn 4 being interspersed in the first yarn group 1 according to other arbitrary rules, etc. As long as the reinforcing yarn 4 is not concentrated in blocks, it falls within the scope of "intermittently distributed among the base yarn 3" as described in this application.

[0046] In the above processing method, the reinforcing yarn 4 is spaced between the base yarns 3 of the first yarn group 1 and interwoven with the second yarn group 2, forming locally high-strength nodes with spaced distribution in the fabric. When the fabric is subjected to local stress concentration or snagging and cracks are generated, the cracks extend along the gaps between the base yarns 3. When they extend to the location of the reinforcing yarn 4, since the tensile strength of the reinforcing yarn 4 is greater than that of the base yarn 3, the crack requires more energy to break, thus effectively blocking the continued propagation of the crack and preventing the crack from penetrating the entire fabric.

[0047] Meanwhile, since the reinforcing yarn 4 is only spaced between the base yarns 3, rather than replacing all of the base yarns 3, most areas of the fabric are still composed of base yarns 3 with lower tensile strength. These areas of base yarn 3 maintain good elastic recovery and low areal density. Therefore, the above processing method improves the tear resistance of the fabric while maintaining the overall elasticity and light weight of the fabric, meeting the performance requirements of sportswear.

[0048] It should be noted that although theoretically, cracks may propagate parallel to the reinforcing yarn 4, that is, continuously extend along the area of ​​the base yarn 3 between two adjacent reinforcing yarns 4 without passing through the reinforcing yarn 4, in actual wearing scenarios, the external forces such as snagging and scratching experienced by the fabric are usually random and multidirectional. The propagation path of the crack is not strictly a straight line in a single direction, but will deflect during the propagation process, thus inevitably encountering the obstruction of the reinforcing yarn 4. Therefore, this should not be used to deny the effectiveness of this application.

[0049] Furthermore, in the above processing method, the reinforcing yarn 4 is not introduced into the fabric through finishing or additional processes after interlacing. Instead, it is distributed intermittently among the base yarns 3 during the configuration of the first yarn group 1, so that the reinforcing yarn 4 is interlaced synchronously with the second yarn group 2 as a component of the first yarn group 1. Since the reinforcing yarn 4 is incorporated into the fabric structure during the interlacing stage, a tight mechanical interlocking relationship is formed between the reinforcing yarn 4, the adjacent base yarns 3, and the second yarn group 2 through warp and weft interlacing. The reinforcing yarn 4 is firmly anchored inside the fabric structure, which also reduces the interface debonding or peeling problems that may occur in subsequent processing.

[0050] In conjunction with the first aspect, according to one embodiment of this application, both the base yarn 3 and the reinforcing yarn 4 are covered yarns, and the method further includes: stretching the core yarn; while the core yarn is in a stretched state, spirally wrapping the covering yarn along the outer periphery of the core yarn to obtain the covered yarn.

[0051] In this embodiment, the core yarn is first stretched to store elastic potential energy under tension. Then, while the core yarn remains stretched, the covering yarn is spirally wrapped around its outer circumference, forming a tight spiral winding structure with the core yarn even when it is stretched. When the core yarn retracts after wrapping, its radial expansion further tightens the spiral wrapping layer, making the wrapping structure more compact and stable. This preparation method results in a covered yarn with high structural density and elastic recovery force even in its natural state, which is beneficial for the fabric to achieve good elastic recovery performance after interweaving.

[0052] In conjunction with the first aspect, according to one embodiment of this application, the core yarn is spandex and the sheath yarn is nylon.

[0053] This embodiment provides a specific example of core yarn and covering yarn selection: Spandex has high elongation at break and excellent elastic recovery, serving as the core yarn to provide sufficient elastic recovery force for the covering yarn; Nylon has high tensile strength and abrasion resistance, serving as the covering yarn to cover the outside of the spandex, protecting the spandex core yarn and providing strength support for the covering yarn. The resulting covered yarn combines elasticity and strength, making it suitable for sports fabrics requiring both elastic recovery and tear resistance.

[0054] Furthermore, the covering yarn is made of recycled nylon, which is produced from industrial waste yarn through recycling, granulation, and respinning. Recycled nylon has mechanical properties comparable to virgin nylon, while reducing the use of petrochemical raw materials and carbon emissions during production. And / or, the core yarn is made of high-resilience sports spandex, which features low modulus, high recovery stress, and low hysteresis loss. Low modulus results in less binding force on the body when the fabric is stretched, making it comfortable to wear; high recovery stress allows the fabric to quickly return to its original state after stretching; and low hysteresis loss ensures high elasticity retention after multiple stretching cycles, preventing it from easily loosening and deforming even after prolonged wear and washing.

[0055] In conjunction with the first aspect, according to one embodiment of this application, when the covering yarn is spirally wrapped around the outer periphery of the core yarn, the wrapping twist is 1000-1200 twists / meter, exemplarily 1000 twists / meter, 1100 twists / meter, or 1200 twists / meter. Controlling the wrapping twist within the range of 1000-1200 twists / meter ensures the tightness of the covering yarn over the core yarn, avoiding loose wrapping and exposure of the core yarn due to excessively low twist, while also avoiding increased yarn rigidity and limited elastic recovery due to excessively high twist.

[0056] In conjunction with the first aspect, according to one embodiment of this application, the core filament is drawn at a draw ratio of 3.5 to 3.8 times. By setting the core filament draw ratio to 3.5 to 3.8 times, compared to the conventional draw ratio of 3.0 to 3.2 times, the core filament is stretched to a greater elongation during the wrapping process, thereby storing greater elastic recovery potential energy. After the fabric is interlaced and shrunk during dyeing and finishing, the core filament releases its recovery force within the fabric, forming a highly resilient core, which is beneficial for improving the elastic recovery rate of the fabric. If the draw ratio is less than 3.5 times, the recovery potential energy stored in the core filament is insufficient, and the improvement in the elastic recovery rate of the fabric is limited; if the draw ratio is greater than 3.8 times, excessive stretching of the core filament may cause damage to the molecular chains, reducing the durability and elasticity retention rate of the core filament.

[0057] In conjunction with the first aspect, according to one embodiment of this application, when preparing the base yarn 3, a first core filament is used as the core filament and a first wrapping filament is used as the wrapping filament; when preparing the reinforcing yarn 4, a second core filament is used as the core filament and a second wrapping filament is used as the wrapping filament; wherein, the fineness of the second core filament is greater than that of the first core filament, and / or, the fineness of the second wrapping filament is greater than that of the first wrapping filament.

[0058] In this embodiment, by making the fineness of the second core filament in the reinforcing yarn 4 greater than that of the first core filament in the base yarn 3, and / or by making the fineness of the second wrapped filament in the reinforcing yarn 4 greater than that of the first wrapped filament in the base yarn 3, the reinforcing yarn 4 has a larger cross-sectional area at both the core filament level and / or the wrapped filament level, thereby making the overall tensile strength of the reinforcing yarn 4 higher than that of the base yarn 3. Since the strength difference between the reinforcing yarn 4 and the base yarn 3 originates from the fineness variation of the same material rather than the introduction of heterogeneous fibers, the two maintain consistency in elastic modulus and hand feel characteristics, and will not cause local abrupt changes in fabric rigidity or uneven elastic recovery due to material differences.

[0059] In conjunction with the first aspect, according to one embodiment of this application, the fineness of the first core filament is 15D to 30D, exemplarily 15D, 20D or 30D; the fineness of the first wrapping filament is 30D to 50D, exemplarily 30D, 40D or 50D; the fineness of the second core filament is 30D to 50D, exemplarily 30D, 40D or 50D; and the fineness of the second wrapping filament is 60D to 90D, exemplarily 60D, 70D, 80D or 90D.

[0060] In this embodiment, by setting the fineness of the first core filament in the base yarn 3 to 15D-30D and the fineness of the first wrapped filament to 30D-50D, the base yarn 3 is relatively fine overall, which can give the fabric a good lightweight feel and breathability. Meanwhile, by increasing the fineness of the second core filament in the reinforcing yarn 4 to 30D-50D and the fineness of the second wrapped filament to 60D-90D, the reinforcing yarn 4 has a larger cross-sectional area and higher breaking strength at both the core and wrapped filament levels, thus creating a significant strength difference with the base yarn 3 and ensuring the reinforcing yarn 4's effective ability to block crack propagation. At the same time, the selection of the above fineness range ensures that the difference in thickness between the reinforcing yarn 4 and the base yarn 3 is within a reasonable range, preventing obvious streaks or abrupt changes in feel on the fabric surface due to excessively coarse reinforcing yarn 4, which helps maintain the uniformity of the fabric's appearance and feel.

[0061] For example, to further improve the fabric's hand feel, the base yarn 3 has a 40D / 34F cover, and the reinforcing yarn 4 has a 70D / 48F cover. Here, the F number indicates the number of monofilaments in the filament. Under the condition of the same total fineness, a larger number of monofilaments makes each monofilament finer, resulting in a softer and more delicate fabric hand feel.

[0062] Furthermore, the covering yarn of the base yarn 3 and the covering yarn of the reinforcing yarn 4 can use the same or different matte finish. For example, the covering yarn of the base yarn 3 can be matte stretch textured yarn (i.e., matte DTY), and the covering yarn of the reinforcing yarn 4 can also be matte DTY; or, the covering yarn of the base yarn 3 can be semi-matte DTY, and the covering yarn of the reinforcing yarn 4 can be fully matte DTY. When the base yarn 3 and the reinforcing yarn 4 use different matte finishes, the area where the reinforcing yarn 4 is located and the area where the base yarn 3 is located will exhibit a subtle difference in gloss on the fabric surface, adding visual depth to the fabric appearance without affecting its mechanical properties.

[0063] In conjunction with the first aspect, according to one embodiment of this application, the first yarn group 1 is a weft yarn and the second yarn group 2 is a warp yarn; when the first yarn group 1 and the second yarn group 2 are interwoven, the second yarn group 2 is set first, and then during the interweaving process, the base yarn 3 and the reinforcing yarn 4 of the first yarn group 1 are alternately introduced in a predetermined order, so that the base yarn 3 and the reinforcing yarn 4 of the first yarn group 1 are interwoven in the warp yarn at intervals.

[0064] When the first yarn group 1 is a weft yarn, the spacing configuration of the reinforcing yarn 4 is achieved by alternately introducing the base yarn 3 and the reinforcing yarn 4 in a predetermined order during the weaving process. This method utilizes the weft feeder or weft selector of the loom to control the sequence, without requiring special adjustments to the warping and reed threading processes. The spacing configuration of the reinforcing yarn 4 can be completed simply by switching the yarns at the weft insertion stage. The process is simple to implement and suitable for conventional weaving equipment such as air-jet looms.

[0065] In conjunction with the first aspect, according to one embodiment of this application, the first yarn group 1 is a warp yarn and the second yarn group 2 is a weft yarn; when the first yarn group 1 and the second yarn group 2 are interwoven, the base yarn 3 and the reinforcing yarn 4 of the first yarn group 1 are alternately warped and threaded through the reed, so that the base yarn 3 and the reinforcing yarn 4 of the first yarn group 1 are arranged alternately, and then the second yarn group 2 is introduced to interweave with the first yarn group 1.

[0066] When the first yarn group 1 is warp, the spacing of the reinforcing yarn 4 is achieved by alternating the base yarn 3 and the reinforcing yarn 4 according to a predetermined pattern during the warping and reeding stages. This method completes the positioning of the reinforcing yarn 4 before interlacing, and the warp yarn arrangement is fixed during interlacing, eliminating the need for yarn switching and ensuring unaffected interlacing efficiency. Simultaneously, precise control of warping and reeding ensures the uniformity of the spacing and the accuracy of the position of the reinforcing yarn 4 within the warp yarns.

[0067] In conjunction with the first aspect, according to one embodiment of this application, the second yarn group 2 is composed entirely of the base yarn 3; or, please refer to... Figure 2 The second yarn group 2 includes a base yarn 3 and a reinforcing yarn 4, and the reinforcing yarn 4 is distributed between the base yarns 3 in the second yarn group 2.

[0068] When the second yarn group 2 is entirely composed of base yarns 3, only the first yarn group 1 contains interspersed reinforcing yarns 4. The fabric has tear-resistant blocking capability in the direction of the first yarn group 1, while the second yarn group 2 is entirely composed of base yarns 3. The fabric maintains better elasticity and a lightweight feel in this direction, making it suitable for applications that require high tear resistance in one direction while being more sensitive to elasticity and comfort in another direction. When the second yarn group 2 also contains interspersed reinforcing yarns 4, the fabric forms an interspersed distribution of reinforcing yarns 4 in both the first yarn group 1 and the second yarn group 2. The reinforcing yarns 4 in the two directions intersect to form a mesh-like tear-resistant skeleton, which can block the propagation of cracks in any direction, giving the fabric stronger all-around tear resistance.

[0069] In conjunction with the first aspect, according to one embodiment of this application, in the first yarn group 1, the total number of reinforcing yarns 4 is less than the total number of base yarns 3.

[0070] By making the total number of reinforcing yarns 4 less than the total number of base yarns 3, most of the yarns in the fabric are still base yarns 3 with lower tensile strength but better elasticity, and only a small amount of reinforcing yarns 4 with higher tensile strength are configured in local positions. In this way, while achieving tear-resistant blocking effect, the impact of reinforcing yarns 4 on the overall weight, elasticity and breathability of the fabric is controlled within a small range.

[0071] In conjunction with the first aspect, according to one embodiment of this application, in the first yarn group 1, the ratio of the number of base yarns 3 to the number of reinforcing yarns 4 is 2:1 to 5:1, for example, 2:1, 3:1, 4:1 or 5:1; and / or, in the first yarn group 1, one reinforcing yarn 4 is distributed at intervals between each adjacent M base yarns 3, and M is not less than 3.

[0072] If the proportion of reinforcing yarn 4 is too high, the fabric's weight and rigidity will increase significantly; if the proportion is too low, the spacing between adjacent reinforcing yarns 4 will be too large, resulting in a still large range of tear propagation and insignificant tear resistance. This embodiment controls the ratio of base yarn 3 to reinforcing yarn 4 within the range of 2:1 to 5:1, ensuring sufficient coverage density of the reinforcing yarn 4 to block cracks while avoiding an excessively high proportion of reinforcing yarn 4 that would affect the overall elasticity and lightweight effect of the fabric. Alternatively, by configuring one reinforcing yarn 4 between at least three adjacent base yarns 3, a sufficient number of base yarns 3 are maintained between adjacent reinforcing yarns 4, ensuring adequate elasticity and breathability in the base yarn 3 area between the reinforcing yarns 4, while maintaining a reasonable spacing between the reinforcing yarns 4 to effectively block crack propagation.

[0073] It should be noted that in the above embodiments, the spacing between adjacent reinforcing yarns 4 can be uniform, that is, the same number of base yarns 3 are spaced between each adjacent reinforcing yarn 4; or it can be gradual, that is, the spacing between the reinforcing yarns 4 gradually increases or decreases along the arrangement direction of the first yarn group 1. When using a gradual spacing, a denser spacing of reinforcing yarns 4 can be configured in areas of the fabric with higher requirements for tear resistance, while a sparser spacing of reinforcing yarns 4 can be configured in areas that are more sensitive to elasticity and breathability, thereby allowing for differentiated design according to the functional requirements of different parts of the fabric.

[0074] In conjunction with the first aspect, according to one embodiment of this application, the base yarn 3 in the first yarn group 1 is interwoven with the second yarn group 2 according to the plain weave pattern; the reinforcing yarn 4 in the first yarn group 1 is interwoven with the second yarn group 2 according to the plain weave pattern, the double plain weave pattern, or the square plain weave pattern.

[0075] The base yarn area 3 uses a plain weave pattern to ensure the fabric's lightweight and breathable properties over a large area. The reinforcing yarn area 4 can use a double plain weave pattern or a square plain weave pattern to make the interlacing points of the reinforcing yarn area 4 denser and more compact, further improving the reinforcing yarn area 4's ability to block crack propagation. By using different weave patterns for the base yarn area 3 and the reinforcing yarn area 4, the local tear resistance can be specifically strengthened without increasing the overall weight of the fabric.

[0076] In conjunction with the first aspect, according to one embodiment of this application, the first yarn group 1 and the second yarn group 2 are interwoven to obtain a fabric, including: interweaving the first yarn group 1 and the second yarn group 2 to form a greige fabric; and sequentially performing a pre-setting treatment, a dyeing treatment, and a finishing treatment on the greige fabric; wherein the temperature of the pre-setting treatment is higher than the temperature of the finishing treatment, and the temperature of the dyeing treatment is lower than the temperature of the finishing treatment.

[0077] The above dyeing and finishing process employs segmented temperature settings: high-temperature pre-setting, low-temperature dyeing, and medium-temperature finishing. The pre-setting process uses the highest possible temperature to fully heat-set the core yarns, eliminating internal stress accumulated during weaving and fixing the molecular chain conformation of the core yarns, thus stabilizing the fabric structure. Because the pre-setting temperature is higher than the temperatures of subsequent processes, the core yarns, locked in the pre-setting stage, are less prone to significant thermal shrinkage or deformation during the subsequent lower-temperature dyeing and finishing processes, thereby ensuring the dimensional stability of the fabric throughout the entire dyeing and finishing process. The dyeing process uses the lowest temperature to avoid the loosening of the already-set fabric structure due to humid and hot conditions. The finishing process uses a temperature between these two, allowing the molecular chains of the wrapped yarns to fully rearrange and rebuild intermolecular hydrogen bonds, forming a stable finishing effect. Simultaneously, this temperature does not damage the core yarn structure fixed in the pre-setting stage.

[0078] Through the above-mentioned segmented temperature settings, the high-tightness interweaving structure of the area where the reinforcing yarn 4 is located is fixed in the pre-setting stage, and the elasticity of the area of ​​the base yarn 3 is retained in the finished product setting stage. The fabric can still maintain good dimensional stability and flatness after multiple washes and ironings.

[0079] It should be noted that the "more dense and compact interlacing points at reinforcing yarn 4" mentioned in this embodiment is not achieved by additionally increasing the warp and weft density, but rather is a natural effect resulting from the larger diameter of reinforcing yarn 4 under the plain weave or square weave pattern. Specifically, in plain or square weaves, due to the larger diameter of reinforcing yarn 4, it exerts a stronger compression effect on adjacent yarns, making the yarn arrangement in the interlacing area more compact and reducing the gaps between yarns. This naturally forms a locally dense fabric structure at the location of reinforcing yarn 4, achieving higher local tear resistance without additional adjustment of the interlacing density.

[0080] Furthermore, the reinforcing yarns 4 are distributed more closely within the fabric, forming a segmented anchoring structure. When the fabric is subjected to external forces such as rubbing or folding, the slippage range of the yarns in the base yarn 3 area is limited to between two adjacent reinforcing yarns 4, preventing the accumulation of large-scale misalignment deformation. Therefore, the spaced distribution of the reinforcing yarns 4 not only improves tear resistance but also inhibits fabric wrinkling, thus enhancing the fabric's wrinkle resistance.

[0081] In conjunction with the first aspect, according to one embodiment of this application, the pre-forming treatment temperature is 185–195°C; and / or, the dyeing treatment temperature is 95–100°C; and / or, the final product setting treatment temperature is 160–170°C. Exemplarily, the pre-forming temperature is 190°C, the speed is 20–30 m / min, preferably 25 m / min; acid dye is used for dyeing, and the dyeing temperature is 98°C; the final product setting temperature is 165°C, and the speed is 20–30 m / min, preferably 28 m / min.

[0082] This embodiment provides an example of processing temperatures, and the aforementioned temperature range is compatible with common fabric materials. Taking a common spandex core yarn and nylon cover yarn covered yarn system as an example, the pre-setting temperature is set to 185-195℃. This temperature range is sufficient to fully heat-set the spandex core yarn and eliminate internal stress. If the temperature is below 185℃, the spandex will not be sufficiently heat-set, and shrinkage may still occur in subsequent processes. If the temperature is above 195℃, the spandex may undergo thermal degradation, resulting in a decrease in elasticity. The dyeing temperature is set to 95-100℃. This temperature range is suitable for dyeing nylon with acid or neutral dyes, ensuring dyeing uniformity and color fastness. At the same time, it is much lower than the pre-setting temperature, so it will not cause the structure of the set fabric to loosen. The finished product setting temperature is set to 160-170℃. This temperature range is sufficient to fully rearrange the nylon molecular chains and rebuild intermolecular hydrogen bonds, forming a stable setting effect, while preventing the spandex from degrading and preserving elasticity. The combination of the above three temperature parameters ensures the structural stability and elasticity retention of the fabric throughout the dyeing and finishing process.

[0083] It should be noted that in the above embodiments, the tensile strength of the reinforcing yarn 4 is greater than that of the base yarn 3 by increasing the fineness (i.e., increasing the diameter) of the reinforcing yarn 4, such as... Figure 1 and Figure 2 As shown, the diameter of the reinforcing yarn 4 is significantly larger than the diameter of the base yarn 3. However, this application is not limited to this implementation. Please refer to... Figure 3 and Figure 4 In other embodiments, the reinforcing yarn 4 has the same or similar diameter as the base yarn 3, and the tensile strength of the reinforcing yarn 4 is greater than that of the base yarn 3 by using different materials. For example, the base yarn 3 is a conventional nylon-covered spandex elastic yarn, while the reinforcing yarn 4 is made of yarns with higher tensile strength, such as high-strength nylon, high-strength polyester, or aramid. Although their diameters are similar, the reinforcing yarn 4 has a higher breaking strength per unit cross-sectional area. In this embodiment, the reinforcing yarn 4 is also distributed at intervals between the base yarns 3 of the first yarn group 1, forming locally high-strength nodes in the fabric, which help to block crack propagation. Because the reinforcing yarn 4 has the same or similar diameter as the base yarn 3, the fabric surface is smoother and more uniform, without streaks or abrupt changes in feel caused by differences in yarn thickness, resulting in better appearance consistency. Figure 3 The example shown is an embodiment in which only the first yarn group 1 is equipped with reinforcing yarn 4. Figure 4 The example shown is an embodiment in which reinforcing yarn 4 is configured in both the first yarn group 1 and the second yarn group 2.

[0084] Secondly, this application also provides a fabric, which is made based on the fabric processing method of any of the embodiments of the first aspect described above.

[0085] Thirdly, this application also provides a fabric comprising a first yarn group and a second yarn group interwoven with each other, the first yarn group comprising a base yarn and reinforcing yarns spaced apart in the base yarn, and the second yarn group comprising a base yarn; wherein the tensile strength of the reinforcing yarn is greater than the tensile strength of the base yarn.

[0086] The beneficial effects of the second and third aspects mentioned above can be referred to in the first aspect or any possible implementation of the first aspect, and will not be elaborated here. Based on the implementations provided in the above aspects, this application can also be further combined to provide more implementations.

[0087] It should be noted that the order of description of the embodiments in this application is not intended to limit the priority of the embodiments.

[0088] The technical effects of this application will be further explained below with reference to specific experimental results.

[0089] The specific parameters of the fabric samples used in the experiment are as follows: The first yarn group 1 is the weft yarn, consisting of base yarn 3 and reinforcing yarn 4. Base yarn 3 is made of recycled nylon 40D / 34F matte DTY twisted and covered with 20D spandex, with a twist of 1000-1200 twists / meter. Reinforcing yarn 4 is made of recycled nylon 70D / 48F matte DTY twisted and covered with 40D spandex, with a twist of 1000-1200 twists / meter. The ratio of base yarn 3 to reinforcing yarn 4 in the first yarn group 1 is 3:1. The spacing between two adjacent reinforcing yarns 4 is approximately 0.8 mm. The second yarn group 2 is the warp yarn, entirely composed of base yarn 3, with the same specifications as the base yarn 3 in the first yarn group 1. Both the base yarn 3 area and the reinforcing yarn 4 area are interwoven according to a plain weave pattern. The finished fabric has a weight of 100-118 g / m², and the fabric composition is 88% nylon and 12% spandex.

[0090] The fabric samples described above were woven using an air-jet loom with a standard loom specification of 20 reed x 3 weft threads x 220cm width x 28 shuttles. The weft yarns were alternately inserted between the base yarn and reinforcing yarn at a 3:1 ratio using a weft feeder and weft selector. The greige fabric specifications were: width 191cm, warp density 112 threads / 10cm, weft density 183.6 threads / 10cm, and weight 85g / m².

[0091] (a) Tear resistance Because the reinforcing yarn 4 is distributed in a 3:1 ratio among the base yarns 3 of the first yarn group 1, the reinforcing yarn 4, due to its larger diameter and higher spandex content, forms multiple high-strength blocking zones along the crack propagation path. Each time a crack propagates to a reinforcing yarn 4, it requires far more energy than the area of ​​the base yarn 3 to continue extending, and the crack tends to terminate after consuming energy at each stage.

[0092] The tear strength of the fabric was tested according to the single-tongue method of GB / T 3917.2, and the results are as follows:

[0093] The warp tear strength is 21N and the weft tear strength is 34N, which are 2.3 times and 3.8 times the qualified standard, respectively, indicating that the spaced distribution structure of the reinforcing yarn 4 can significantly improve the tear resistance of the fabric.

[0094] (ii) Elastic recovery performance In this fabric, base yarn 3 accounts for 75% of the total weft yarn in the first yarn group, maintaining the main elasticity of the plain weave elastic structure. The reinforcing yarn 4 has a horizontal stripe spacing of approximately 0.8mm and a relatively small area, thus having a limited impact on the overall tensile elongation of the fabric. Simultaneously, the 40D spandex in reinforcing yarn 4 has stronger shrinkage force than the 20D spandex in base yarn 3. After the fabric is stretched and released, the area of ​​reinforcing yarn 4 acts as a high-shrinkage elastic band, driving the fabric to shrink uniformly, which is beneficial for improving elastic recovery performance.

[0095] The elastic recovery rate of the fabric was tested according to ASTM D3107, and the results are as follows:

[0096] The elastic recovery rate meets the performance requirements of elastic sports fabrics, indicating that the spaced distribution structure of reinforcing yarn 4 provides a tear-resistant skeleton without sacrificing the basic elasticity of the fabric.

[0097] (III) Comprehensive Mechanical Performance

[0098] The tensile strength far exceeds the qualified standard, and the seam slippage is minimal, indicating that the spaced distribution structure of reinforcing yarn 4 not only does not sacrifice the main strength of the fabric, but also improves the overall mechanical stability of the fabric through the skeletal effect of local high-strength nodes.

[0099] (iv) Dimensional stability

[0100] The shrinkage rate after washing and the dimensional change rate after ironing are both within the qualified range and the values ​​are small, indicating that the fabric structure is stable after the dyeing and finishing process, the high-density skeleton structure at the 4 horizontal strips of the reinforcing yarn is effectively fixed, and the fabric can still maintain good flatness after multiple washes and ironings.

[0101] To further illustrate the technical effects of this application, the following comparative experiment was designed: All embodiments and comparative examples adopted the following basic preparation process: Elastic covered yarn was used as the base yarn 3 and reinforcing yarn 4, prepared by spirally covering spandex core yarn and nylon cover yarn. The second yarn group 2 was the warp yarn, entirely composed of base yarn 3; the first yarn group 1 was the weft yarn, including base yarn 3 and reinforcing yarn 4, with reinforcing yarn 4 interspersed among the base yarns 3. Both the base yarn 3 and reinforcing yarn 4 regions were interwoven according to a plain weave pattern. The only difference between the embodiments and comparative examples was the parameter differences listed in the table below; all other conditions remained the same.

[0102] Example 1: The base yarn 3 is 40D nylon + 20D spandex, the reinforcing yarn 4 is 70D nylon + 40D spandex, the twist is 1100 twists / meter, and the spandex draw ratio is 3.6 times; the ratio of the number of base yarn 3 to reinforcing yarn 4 in the first yarn group 1 is 1:1.

[0103] Example 2: The difference from Example 1 is that the ratio of the number of base yarn 3 to reinforcing yarn 4 in the first yarn group 1 is adjusted to 2:1.

[0104] Example 3: The difference from Example 1 is that the ratio of the number of base yarn 3 to reinforcing yarn 4 in the first yarn group 1 is adjusted to 3:1.

[0105] Example 4: The difference from Example 1 is that the ratio of the number of base yarn 3 to reinforcing yarn 4 in the first yarn group 1 is adjusted to 4:1.

[0106] Example 5: The difference from Example 1 is that the ratio of the number of base yarn 3 to reinforcing yarn 4 in the first yarn group 1 is adjusted to 5:1.

[0107] Example 6: The difference from Example 1 is that the ratio of the number of base yarn 3 to reinforcing yarn 4 in the first yarn group 1 is adjusted to 8:1.

[0108] Example 7: The difference from Example 3 is that the nylon fineness of reinforcing yarn 4 is adjusted to 50D, and the spandex core yarn fineness of reinforcing yarn 4 is adjusted to 20D.

[0109] Example 8: The difference from Example 3 is that the nylon fineness of the reinforcing yarn 4 is adjusted to 90D.

[0110] Example 9: The difference from Example 3 is that the draw ratio of the spandex core yarn is adjusted to 3.0 times.

[0111] Example 10: The difference from Example 3 is that the draw ratio of the spandex core yarn is adjusted to 3.2 times.

[0112] Example 11: The difference from Example 3 is that the draw ratio of the spandex core yarn is adjusted to 4.0 times.

[0113] Example 12: The difference from Example 3 is that the draw ratio of the spandex core yarn is adjusted to 4.2 times.

[0114] Comparative Example 1: The first yarn group 1 does not contain reinforcing yarn 4, and is composed entirely of base yarn 3. The specifications of base yarn 3 are 40D nylon + 20D spandex, which is a conventional four-way stretch fabric.

[0115] Comparative Example 2: The first yarn group 1 does not contain reinforcing yarn 4, and is composed entirely of yarn of the same specification, namely 70D nylon + 40D spandex, that is, the fabric is made of coarse denier yarn.

[0116] The parameters of each embodiment and comparative example are summarized in Table 1: Table 1 Fabric preparation parameters

[0117] The fabrics prepared in the above embodiments and comparative examples were tested for tear strength (GB / T 3917.2 single tongue method), elastic recovery rate (ASTM D3107), and fabric weight, respectively. The results are shown in Table 2.

[0118] Table 2 Test Results

[0119] The test results above are analyzed as follows: Data from Examples 1-6 show that as the proportion of reinforcing yarn 4 decreases, the weft tear strength gradually decreases, the weft elastic recovery rate gradually increases, and the basis weight gradually decreases. In Comparative Example 1, which does not contain reinforcing yarn 4, the weft tear strength is only 11N; the weft tear strength of Example 3 (3:1) is 34N, 3.1 times that of Comparative Example 1, while the weft elastic recovery rate is 85%, meeting the performance requirements of high-elasticity sports fabrics. When the ratio of base yarn 3 to reinforcing yarn 4 is 2:1, the weft tear strength further increases to 38N, and the weft elastic recovery rate is 81%, resulting in stronger tear resistance but a slight decrease in elasticity; when the ratio is 1:1, the weft tear strength reaches 41N, and the weft elastic recovery rate drops to 78%. The above data indicate that within the range of 2:1 to 5:1, a balance between tear resistance and elasticity can be achieved based on the actual application scenario, with a 3:1 ratio showing a more balanced overall performance.

[0120] Data from Examples 3, 7, and 8 show that as the fineness of reinforcing yarn 4 increases, the weft tear strength improves, but the weft elastic recovery rate decreases and the basis weight increases. When the nylon fineness of reinforcing yarn 4 is too low, the strength difference between reinforcing yarn 4 and base yarn 3 is insufficient, and the tear-resistant blocking effect is weakened; when the nylon fineness of reinforcing yarn 4 is too high, the elastic recovery rate is significantly lost. When the nylon fineness of reinforcing yarn 4 is in the range of 60D to 90D, the overall performance between tear resistance and elasticity is better.

[0121] Data from Examples 3, 9-12 show that the elastic recovery rate is low when the draw ratio is too low, and it also decreases when the draw ratio is too high. The fabric exhibits optimal elastic recovery performance when the draw ratio is in the range of 3.5 to 3.8.

[0122] In Comparative Example 2, the first yarn group 1 consisted entirely of coarse denier yarns, with a weft tear strength of only 15N. In Example 3, the base yarn 3 and reinforcing yarn 4 were configured in a 3:1 ratio, resulting in a weft tear strength of 34N, which is 2.3 times that of Comparative Example 2, with only a 2g / m² increase in weight. The above comparison demonstrates that simply thickening the yarn as a whole without creating an alternating thick-to-thin structure has limited effect on improving tear resistance. The localized blocking structure formed by the alternating distribution of the base yarn 3 and reinforcing yarn 4 is the key to the significant improvement in tear resistance.
