Description

Technical Field

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

[0002] With the continuous advancement of materials science and textile technology, consumers are placing higher demands on the functionality and comfort of footwear products. Especially in the fields of athletic shoes, outdoor shoes, and casual shoes for everyday wear, the performance indicators of the shoe upper, as a key component that comes into direct contact with the foot and affects the wearing experience, are receiving increasing attention. An ideal shoe upper should possess good breathability to keep feet dry and avoid stuffiness; moderate elasticity to provide a comfortable fit and dynamic adaptability; and sufficient physical strength to ensure the durability of the upper and effective support for the foot.

[0003] However, in pursuit of breathability, some existing technologies use monofilaments as raw materials for weaving or employ large-mesh knitted structures. While these fabrics can create a relatively open pore structure, thus achieving better air circulation, their drawbacks are also quite obvious. For example, fabrics woven from monofilaments are often quite stiff and lack softness, resulting in a rough feel, poor wearing comfort, and potentially causing friction and discomfort. Furthermore, excessively large mesh structures can sometimes sacrifice the fabric's strength and tear resistance, and easily trap dirt and grime, affecting aesthetics and lifespan. Other existing technologies attempt to use natural fibers (such as cotton yarn) as raw materials for shoe uppers. Natural fibers like cotton yarn have good moisture absorption and skin-friendliness, which can improve wearing comfort to some extent. However, these fibers often perform poorly in terms of breathability, especially under wet conditions, where breathability further decreases, easily leading to damp feet. More importantly, the inherent strength of natural fibers, especially wet strength, is usually low, making it difficult to meet the high durability and deformation resistance requirements of applications such as athletic shoes. While ordinary synthetic fiber (such as polyester and nylon) woven or knitted fabrics can improve strength and elasticity to some extent by adjusting fabric density and structure, achieving high breathability often requires reducing fabric density or using a special loose structure, which may result in insufficient fabric strength or poor elasticity. Conversely, using a high-density, tight structure in pursuit of high strength will significantly sacrifice the fabric's breathability. Therefore, under traditional weaving concepts and structural designs, it is difficult to achieve a balance between breathability, slight elasticity, and high strength economically and effectively. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background technology and provide a woven fabric for footwear that can improve the problem that it is difficult to achieve a balance between breathability, micro-elasticity and high strength in footwear fabrics in an economical and effective manner in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Technical Solution 1: A woven fabric for shoes, comprising: warp yarns, wherein the warp yarns are polyester twisted yarns; and weft yarns, wherein the weft yarns include: a first weft yarn, wherein the first weft yarn is coarse polyester twisted yarn and is formed by at least two parallel strands forming a first weft yarn strand; and a second weft yarn, wherein the second weft yarn is fine polyester twisted yarn; wherein the first weft yarn strands are interwoven with the warp yarns in a weft-flat weave structure, the weft-flat weave structure defining gaps that extend through the fabric thickness between the first weft yarn strands and in the interweaving area between the first weft yarn strands and the warp yarns; and the second weft yarn is in a single, non-interwoven state, contained within a channel space formed by adjacent first weft yarn strands and a portion of the warp yarns, extending along the weft direction.

[0007] Technical Solution 2 based on Technical Solution 1: The arrangement relationship between the first weft yarn and the second weft yarn in the fabric is as follows: one second weft yarn is set between every N first weft yarns, where N is an integer greater than or equal to 1.

[0008] Technical Solution 3 based on Technical Solution 1: The arrangement of the first weft yarn and the second weft yarn in the fabric is as follows: one second weft yarn is set between every two first weft yarns.

[0009] Technical Solution 4 based on Technical Solution 1: The first weft yarn strand is formed by two coarse polyester twisted yarns arranged side by side.

[0010] Technical Solution 5 based on Technical Solution 1: The weft-fold flat weave structure is a 6 / 6 weft-fold flat weave.

[0011] Technical Solution Six based on Technical Solution One: The fineness of the second weft yarn is 150 denier to 300 denier, and the twist is 300 twists / meter.

[0012] Technical solution seven based on technical solution one: The fineness of each coarse polyester twisted yarn constituting the first weft yarn strand is 450 denier to 600 denier, and the twist is 250 twists / meter.

[0013] Technical solution eight based on technical solution one: The warp yarn is a 100 denier, 680 twists / meter polyester twisted filament.

[0014] Technical Solution Nine based on Technical Solution One: Both the first weft yarn and the second weft yarn are polyester low-elastic twisted yarns.

[0015] 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:

[0016] Technical Solution 1 provides a woven fabric for footwear, whose unique yarn system and fabric structure design constitute a closely coordinated technical solution that achieves the unity of the three core properties of breathability, micro-elasticity and high strength, effectively improving the problem that it is difficult to meet these requirements at the same time in the existing technology.

[0017] The warp yarns are made of twisted polyester, providing the fabric with basic strength and dimensional stability, forming the longitudinal skeleton of the fabric. The weft system includes a first weft yarn and a second weft yarn. The first weft yarn is a coarse twisted polyester yarn, and at least two yarns are arranged side by side to form the first weft ply. These coarse, side-by-side yarn plies are key to forming the transverse structure and main air-permeable channels of the fabric. When the first weft ply interweaves with the warp yarns in a weft-flat weave, the coarser yarn ply itself, combined with the fact that the weft flat weave usually results in a longer float on the fabric surface, creates relatively large gaps between the yarn plies and in the interweaving areas between the yarn plies and the warp yarns, which are able to penetrate the fabric thickness. These gaps are the initial channels for air circulation. Without this combination of coarse yarn plies and a specific weave, it would be difficult to form sufficient initial air-permeable channels.

[0018] The second weft yarn, a fine twisted polyester yarn, plays a crucial role in achieving performance balance in this design. It exists as a single strand and does not interweave with the warp yarns. Instead, it is contained within a channel space formed by the adjacent first weft yarn strands and a portion of the warp yarns, extending along the weft direction. In this "non-interlacing" and "contained within a channel" configuration, the second weft yarn, unlike traditional yarns that are fixed through interlacing, utilizes its own physical volume and a certain stiffness to provide physical support and stability to the gaps formed by the first weft yarn strands and the weft-weighted plain weave. Without this support from the second weft yarn, these initial gaps would easily collapse and close during fabric stress or use, leading to decreased or complete loss of breathability. Therefore, the first weft yarn system forms the initial breathable channels, while the second weft yarn system maintains the stability of these channels. It is this synergistic effect between the two that achieves efficient and durable breathability.

[0019] Furthermore, the use of twisted polyester yarn throughout the fabric leverages the inherent molecular properties of polyester to impart a degree of resilience. Simultaneously, the relatively long floats inherent in the fabric structure, particularly in weft-heavy plain weaves, and the non-interlacing state of the second weft yarn, provide the yarns with minute spaces for movement and deformation under stress. This structural "looseness," combined with the material's elastic potential, contributes to the fabric's micro-elasticity, thereby improving wearing comfort. Simply having the material's inherent elasticity without this structurally provided space is insufficient to achieve the comfortable micro-elastic effect.

[0020] Furthermore, the first weft yarn, due to its "coarse" and "parallel" characteristics, significantly enhances the fabric's load-bearing capacity in the weft direction. The effective interweaving between the warp yarns and the first weft yarn forms the main load-bearing framework of the fabric. Although the second weft yarn does not participate in direct interweaving, its filling and stabilizing effects limit the excessive displacement and structural disintegration risk of the main load-bearing units, namely the first weft yarn and the warp yarns, under stress. This indirectly enhances the integrity and durability of the overall structure, thereby improving the overall strength of the woven fabric.

[0021] Therefore, this technical solution tightly couples the functional elements of "constructing initial breathable channels," "stabilizing breathable channels," "providing elastic space," and "constructing a strong and resilient skeleton" through the specific composition and interlacing method of the warp yarns and the first weft yarn, the specific shape and non-interlacing containment method of the second weft yarn, and the overall material selection. Each structural feature contributes an indispensable part to the final comprehensive performance, namely breathability, micro-elasticity, and high strength. Furthermore, their relationships are not simply a superposition of performance characteristics, but rather a synergistic relationship of mutual dependence and reinforcement. This design allows the fabric as a whole to overcome the shortcomings of existing technologies where a single performance is prominent but other performances are difficult to achieve simultaneously, forming a complete and self-consistent technical solution that can meet multiple performance requirements at the same time. The woven fabric for footwear provided by this technical solution offers durable and excellent breathability, while achieving comfortable micro-elasticity while ensuring high strength, thus achieving a good synergistic unity of performance across the three dimensions.

[0022] In technical solution two, the arrangement of the first and second weft yarns in the fabric is further defined as follows: one second weft yarn is placed between every N first weft yarns, where N is an integer greater than or equal to 1. This ensures that the air gaps stabilized and maintained by the second weft yarns can achieve a regular and predictable uniform distribution throughout the width and length of the fabric. This periodic arrangement makes the fabric's air permeability consistent macroscopically, avoiding the problem of some areas having good air permeability while others have poor air permeability due to structural randomness, thereby improving the uniformity of the overall wearing experience. Furthermore, by adjusting the value of the integer N, the density of the air channels stabilized by the second weft yarns in the fabric can be directly controlled. For example, a smaller N value, such as N equal to 1 or 2, means a denser distribution of the second weft yarns, which theoretically can stabilize more air pores, potentially resulting in a higher overall air permeability. A larger N value, on the other hand, means a relatively sparse distribution of the second weft yarns. This adjustability provides a clear technical means to customize the breathability level of fabrics according to the specific application needs of different footwear styles, such as the need for high breathability in summer or a certain degree of warmth in spring and autumn. Therefore, by introducing this regular arrangement, this technical solution not only ensures the uniformity and stability of fabric performance, but also gives the fabric performance the flexibility to be designed and adjusted.

[0023] In technical solution three, the arrangement of the first and second weft yarns in the fabric is further defined as one second weft yarn between every two first weft yarns. This ratio ensures a sufficient density of second weft yarns to effectively stabilize a large number of air gaps, thereby guaranteeing significant and reliable overall air permeability of the fabric. Simultaneously, compared to a denser arrangement of second weft yarns, such as when N equals 1, a 1:2 ratio ensures excellent air permeability while avoiding the potential decrease in structural strength or dimensional stability of the fabric in certain directions due to an excessively high proportion of non-interlaced second weft yarns, while also making more economical use of materials. Conversely, compared to a sparser arrangement, such as when N is greater than 2, it more effectively utilizes the stabilizing effect of the second weft yarns on the air pores.

[0024] In Technical Solution Four, the first weft yarn is defined as being formed by two coarse polyester twisted yarns running side by side. Using two coarse polyester yarns side-by-side to form a single strand, compared to using a single, thicker yarn with a diameter equal to the sum of the two yarns, achieves a similar overall strand thickness. Furthermore, the tiny gaps naturally formed between the two yarns when they are side-by-side may contribute to overall breathability, making the breathability path more efficient. In addition, a strand composed of two yarns has better flexibility when bent than a single yarn of equivalent thickness because a slight relative slippage can occur between the two yarns. This increased flexibility helps improve the fabric's feel, making it less stiff and enhancing comfort during dynamic wear.

[0025] In technical solution five, the weft-weight plain weave structure is specifically defined as a 6 / 6 weft-weight plain weave. In weaving principles, a 6 / 6 weft-weight plain weave means that the weft yarn, as the first weft strand, forms a complete weave cycle unit of six warp yarns on one side of the fabric, creating relatively long floats within this cycle. For example, the weft yarn floats above or below several consecutive warp yarns, depending on the weave pattern design and the heddle threading method. This longer weft float directly results in structurally and inevitably creating relatively obvious grooves or pores, typically penetrating the fabric thickness, at the edges of these floats and between adjacent first weft strands. These pores formed by the specific weave structure are the main channels through which the fabric achieves its breathability. Therefore, this definition ensures the uniformity and effectiveness of these breathable channels, further guaranteeing the fabric's breathability.

[0026] In technical solution six, the fineness of the second weft yarn is limited to 150 to 300 denier, and the twist is 300 twists / meter. These parameters ensure that the yarn can optimally perform its function of stabilizing the air gap, while minimizing any adverse effects on airflow and guaranteeing its structural integrity and durability. The fineness range of 150 to 300 denier ensures that the second weft yarn remains sufficiently fine relative to the thicker first weft yarn strands that form the boundaries of the main airflow channels. This fineness ensures that when contained within the channel space formed by the first weft yarn strands, it will not excessively occupy the channel space due to its own size, thereby preventing blockage or significantly reducing the effective cross-section for airflow, thus guaranteeing air permeability.

[0027] In technical solution seven, the fineness of each coarse polyester twisted yarn constituting the first weft ply is limited to 450 denier to 600 denier, with a twist of 250 twists / meter. This parameter limitation ensures that it possesses the necessary strength, volume, and morphological stability, laying a solid material foundation for the overall high strength and significant breathability of the fabric. When yarns within this coarseness range are arranged side-by-side to form the first weft ply, they possess sufficient robustness, thus facilitating the formation of breathable gaps for efficient airflow. Simultaneously, such coarse yarn ply also provides the fabric with a robust weft skeleton, enabling it to withstand greater external loads and exhibiting excellent abrasion and tear resistance. The 250 twists / meter twist further optimizes these roving properties. Appropriate twist can improve the cohesion of fibers in the yarn, thereby increasing the yarn's breaking strength and abrasion resistance. It also imparts a certain degree of structural roundness and morphological stability to the yarn, making it less prone to accidental splitting or excessive deformation during weaving and use, ensuring the regularity of the fabric structure and the stability of its performance.

[0028] Technical Solution 8 specifies that the warp yarn is 100 denier, 680 twist / meter polyester twisted filament, i.e., FDY. The high twist of 680 twist / meter gives the warp yarn excellent tensile strength and low elongation at break, ensuring that the fabric can withstand greater tension in the warp direction without easily breaking or undergoing permanent deformation. Polyester filament, especially FDY (fully drawn yarn), inherently possesses high strength and low elongation characteristics, and its evenness and few defects ensure the uniformity and stability of warp yarn performance. The 100 denier fineness makes the warp yarn finer than the weft yarn, especially the thicker first weft strand. This contrast in fineness helps to form a clearer and more defined weave structure during weaving, making the breathable gaps formed by the weft yarn more regular and prominent. Furthermore, the finer warp yarn also helps to achieve a lighter weight and a finer fabric surface while maintaining strength, improving the overall quality and wearing comfort of the fabric.

[0029] In Technical Solution Nine, both the first and second weft yarns are specified as being made of low-elasticity twisted polyester yarn. This material limitation gives the fabric a moderate degree of micro-elasticity, better fluffiness, and significantly improved wearing comfort and dynamic adaptability, while maintaining the strength advantages of polyester. Low-elasticity polyester yarn is obtained by processing polyester filaments through specific deformation processes, such as false twisting. Its microstructure exhibits a certain degree of curl or fluffiness. This curled structure gives the low-elasticity yarn and the fabric it forms better elongation and elastic recovery than ordinary polyester filaments, such as FDY. When the fabric is stretched, these curled fibers can partially stretch, and after the external force is removed, they can recover their original shape well. This is the direct source of the fabric's "micro-elasticity" characteristic, providing a better dynamic fit. The curl of the fibers also makes the yarn fluffier and softer, resulting in fabrics with a fuller hand feel and less stiffness, reducing the discomfort that may arise from traditional high-strength polyester fabrics.

[0041] Terminology Definition

[0042] The use of terms such as "first," "second," or "third" is to distinguish different objects, not to describe a specific order.

[0043] Polyester twisted yarn: refers to yarn made by twisting polyester filaments or staple fibers to give the yarn a certain twist direction and twist degree, thereby increasing its strength, abrasion resistance, cohesion, or producing a specific appearance effect. Unless otherwise specified, polyester in this invention usually refers to polyethylene terephthalate (PET) fiber.

[0044] First weft yarn: refers to a collection of yarns consisting of at least two coarse polyester twisted yarns arranged side-by-side or slightly twisted together, introduced into the weft direction of the fabric as a whole unit. Its main characteristic is that it is relatively thick, and it mainly serves to create air permeability and provide weft strength in the fabric.

[0045] The second weft yarn refers to a finer polyester twisted yarn compared to the first weft yarn. Its main characteristic in this invention is that it exists in a non-interlaced state within the fabric structure, thus stabilizing the air permeability gaps.

[0046] Weft-weighted plain weave: a type of fabric weave characterized by the weft yarns forming a dominant covering effect on one surface of the fabric (usually the right side). This is manifested by the longer float length of the weft yarns or the arrangement of multiple weft yarns side by side, resulting in weft-shaped ribs on the fabric surface or the weft yarns dominating the appearance.

[0047] Non-interlacing state: Specifically refers to the configuration of the second weft yarn in this invention, that is, when the second weft yarn passes through the fabric, it does not interlace with the warp yarn in the traditional, periodic up-and-down shuttle manner, but is contained within the space defined by other yarns (such as warp yarns and the first weft yarn strand).

[0048] Channel space: refers to the specific space in the fabric structure of the present invention that is formed by adjacent first weft yarn strands and part of the warp yarns, extending along the weft direction of the fabric, and used to accommodate the second weft yarn 3.

[0049] Denier (D): A unit of yarn fineness, defined as the weight in grams of 9000 meters of yarn at standard moisture regain. The higher the denier value, the coarser the yarn.

[0050] Twist / meter (T / M): A unit of yarn twist, referring to the number of twists per meter of yarn length.

[0051] FDY (Fully Drawn Yarn): A type of synthetic fiber filament produced by a one-step or multi-step spinning and drawing process. It has high orientation and crystallinity, and exhibits high strength and low elongation.

[0052] DTY (Draw Textured Yarn, also known as polyester low elasticity yarn): a type of synthetic fiber filament, usually made from POY (pre-oriented yarn) through stretching and false twisting. It has a certain degree of crimp and bulkiness, thus giving the yarn and fabric good elasticity and a full hand feel.

[0053] High-temperature heat setting: a finishing process that involves treating fabrics under certain tension in a high-temperature environment (usually 170℃-210℃ for polyester) for a period of time. By utilizing the thermoplasticity of fibers, the fabric structure, dimensions, and yarn morphology (such as crimp) are stabilized, internal stress is eliminated, and the appearance and performance of the fabric are improved.

[0054] Example

[0055] This embodiment relates to a woven fabric for footwear, as shown in the reference... Figures 1 to 3 This woven fabric can improve the problem of achieving a balance between breathability, elasticity, and high strength in footwear fabrics in an economical and effective manner, which is difficult to achieve in existing technologies.

[0056] The woven fabric for shoes involved in this embodiment includes warp yarn 1, which is polyester twisted yarn; and weft yarn, which includes: a first weft yarn, which is coarse polyester twisted yarn and is formed by at least two parallel first weft yarn strands 2; and a second weft yarn 3, which is fine polyester twisted yarn; wherein, the first weft yarn strand 2 and the warp yarn 1 are interwoven with a weft-flat weave structure, and the weft-flat weave structure defines the gaps that run through the fabric thickness between the first weft yarn strands 2 and in the interweaving area between the first weft yarn strands 2 and the warp yarn 1; and the second weft yarn 3 is in a single, non-interwoven state, and is contained in a channel space formed by adjacent first weft yarn strands 2 and part of the warp yarn 1 and extending along the weft direction.

[0057] The warp yarn 1 that constitutes this fabric is made of twisted polyester yarn. During the weaving process, these warp yarns 1 are arranged on the loom according to a preset warp density, forming the longitudinal basic skeleton of the fabric. The choice of polyester material ensures that the warp yarn 1 has good strength and abrasion resistance, while the twisting process further enhances its strength and structural stability.

[0058] The weft system of the fabric comprises a first weft ply 2 and a second weft yarn 3. The first weft ply 2 is composed of coarse polyester twisted yarns. Specifically, each of these coarse polyester twisted yarns is a first weft yarn, and these first weft yarns are arranged in pairs to form a single first weft ply 2. The method of combining multiple rovings into a single ply for weaving can be achieved by setting up multiple sheds for weft insertion on the loom or by simultaneously feeding multiple yarns into the same shed. This structure allows the first weft ply 2 to occupy a relatively significant volume and lateral width in the fabric, serving as the main unit for creating air gaps and bearing weft strength. The second weft yarn 3 is a fine polyester twisted yarn, with a fineness significantly smaller than that of the individual coarse polyester twisted yarns constituting the first weft ply 2.

[0059] In terms of fabric structure, the first weft yarn 2 interweaves with the warp yarn 1 in a weft-flat weave. The characteristic of a weft-flat weave is that the weft yarn forms a long float or multiple parallel strands covering the warp yarn 1 on one surface of the fabric, making the weft yarn dominant on the fabric surface, thus easily forming weft ribs and gaps. The realization of this weave depends on the precise setting of the heald frame lifting sequence and the heald threading method on the loom. Referring to the planar structure and the cross-sectional structure along the weft direction of the fabric shown in the attached diagram, due to the relatively thick first weft yarn 2 and the use of a weft-flat weave, these two factors combine to physically and naturally define relatively large gaps that can penetrate the fabric thickness between adjacent first weft yarns 2, and in the interweaving area between the first weft yarn 2 and the warp yarn 1. These gaps constitute the initial channels for air circulation.

[0060] See attached document Figure 1-3In the structure shown, the second weft yarn 3 is a single strand and does not interweave with the warp yarns 1 in the traditional vertical direction within the fabric structure; that is, it is in a non-interwoven state. It is housed within a channel space formed by the adjacent first weft yarn strands 2 and a portion of the warp yarns 1, extending along the weft direction of the fabric. Specifically, this can be achieved by controlling the opening action of the jacquard or dobby loom, so that at the shed where the second weft yarn 3 is introduced, the warp yarns 1 form a separate vertical channel instead of a traditional interlaced shed. The second weft yarn 3 then passes directly through this channel defined by the upper and lower layers of warp yarns 1 (or a portion of the warp yarns 1) and the first weft yarn strands 2 on both sides. Because the second weft yarn 3 does not interweave with the warp yarns 1, it utilizes its own physical volume and a certain rigidity to provide physical support and stability to the gaps formed by the first weft yarn strands 2 and the weft-weighted plain weave, preventing these gaps from collapsing and closing during fabric stress or use, thus ensuring long-lasting breathability.

[0061] Furthermore, the arrangement of the first weft yarn 2 and the second weft yarn 3 in the fabric is as follows: one strand of the second weft yarn 3 is placed between every N strands of the first weft yarn 2, where N is an integer greater than or equal to 1. Specifically, the first weft yarn 2 and the second weft yarn 3 are arranged in a 1:N ratio, where N is an integer greater than or equal to 1. This arrangement is achieved by precisely controlling the feeding sequence of different types of weft yarns during the weaving process. For example, when N equals 1, the weft structure of the fabric is such that one strand of the first weft yarn 2 is followed immediately by one strand of the second weft yarn 3, and then this sequence is repeated. When N equals other integers, N strands of the first weft yarn 2 are woven in before one strand of the second weft yarn 3 is woven in. The choice of the N value directly affects the density of the air-permeable channels in the fabric and the uniformity of the distribution of the stabilizing effect of the second weft yarn 3 on these channels.

[0062] Based on this, the N value is selected as 2. That is, the arrangement of the first weft yarn 2 and the second weft yarn 3 in the fabric is as follows: one strand of the second weft yarn 3 is placed between every two strands of the first weft yarn 2. During the weaving process, the specific weft yarn feeding sequence is: first, two strands of the first weft yarn 2 are woven in, then one strand of the second weft yarn 3 is woven in, then two more strands of the first weft yarn 2 are woven in, then one more strand of the second weft yarn 3 is woven in, and so on, repeating this cycle. This 2:1 arrangement is considered to achieve a better balance between ensuring sufficient air permeability and pore density, the effective stabilizing effect of the second weft yarn 3 and maintaining the overall structural strength of the fabric, and considering production efficiency.

[0063] Furthermore, the first weft strand 2 is formed by two coarse polyester twisted yarns arranged side by side. During weaving, these two independent coarse polyester twisted yarns are drawn from their respective bobbins or warp beams and simultaneously fed into the same shed as a bundled yarn unit, thereby forming a weft strand in the fabric composed of two yarns arranged side by side. These two yarns remain essentially side by side during weaving. Using two yarns arranged side by side to form a strand, compared to using a single, coarser yarn with a similar overall fineness, can achieve a similar overall strand thickness while providing better flexibility and coverage. Furthermore, the naturally formed micro-interface between the two yarns also positively impacts breathability.

[0064] In this fabric, the weft-to-plain weave structure is 6 / 6. 6 / 6 weft-to-plain weave is a specific fabric weave type where, in a complete weave cycle, the first weft yarn 2 (woven as a single unit) floats or sinks above or below several consecutive warp yarns 1 on one surface of the fabric, with a total of 6 warp yarns 1 in the cycle. For example, the first weft yarn 2 could float above 5 warp yarns 1 and then sink below 1 warp yarn 1, or other weaving patterns that satisfy the requirement of 6 warp yarns 1 per cycle and produce a significant weft surface effect. Achieving this specific weave requires precise setting of the heald frame lifting sequence on the loom (controlled by an opening device such as a dobby or jacquard mechanism) and the corresponding heald pattern and weave swatch. Using a 6 / 6 weft-to-plain weave allows the first weft yarn 2 to form a more significant and regular weft float or cover on the fabric surface, effectively defining uniformly sized and regularly distributed breathable gaps.

[0065] More specifically, the second weft yarn 3 has a fineness of 150 to 300 denier and a twist of 300 twists / meter. Furthermore, each coarse polyester twisted filament constituting the first weft yarn strand 2 has a fineness of 450 to 600 denier and a twist of 250 twists / meter. And the warp yarn 1 is a 100 denier, 680 twist / meter polyester twisted filament.

[0066] For example, a 200 denier, 300 twist per meter S-twist polyester yarn can be selected as the second weft yarn 3. This choice of fineness and twist range is based on the fact that the second weft yarn 3 primarily functions to stabilize the air gaps in the fabric without blocking airflow channels. A fineness of 150 to 300 denier makes it sufficiently thin relative to the thicker first weft yarn 2, allowing it to be easily accommodated within the channel space formed by the first weft yarn 2 and the warp yarn 1 without excessively occupying space, thus ensuring air permeability. Simultaneously, the 300 twist per meter provides this yarn with sufficient inherent strength and structural stability, making it less prone to loosening or breakage during weaving and use.

[0067] Furthermore, if the first weft ply 2 is formed by two yarns side by side, each of these two yarns can be selected as an S-twist polyester yarn with a fineness of 500 denier and a twist of 250 twists / meter. Thus, the total fineness of the formed first weft ply 2 is 1000 denier. This selection of single yarn fineness and twist range aims to ensure that the first weft ply 2 has sufficient robustness and strength to form a reasonably sized air gap and provide a solid weft skeleton for the fabric.

[0068] Warp 1 can typically be made of FDY yarn. Its 100 denier fineness makes warp 1 relatively finer than the weft yarns (especially the thicker first weft strand 2), which helps to create a clearer, more defined weave structure during weaving and makes the air gaps formed by the weft yarns more regular and prominent. The high twist of up to 680 twists / meter gives warp 1 excellent tensile strength, abrasion resistance, and dimensional stability, ensuring that the fabric can withstand greater tension in the warp direction without easily breaking or undergoing permanent deformation.

[0069] Furthermore, both the first weft yarn and the second weft yarn 3 are made of polyester low-elasticity twisted yarn. Polyester low-elasticity twisted yarn is a yarn obtained by processing polyester filament through specific texturing processes (such as false twisting). In its microstructure, the fibers exhibit a certain degree of crimping or loose structure. This crimped structure gives the low-elasticity yarn itself and the fabric it forms better elongation and elastic recovery than ordinary polyester filament (such as FDY), and also makes it feel fluffier and softer. When both the first weft yarn and the second weft yarn 3 are made of polyester low-elasticity twisted yarn, the overall micro-elasticity and wearing comfort of the fabric will be significantly improved, while still maintaining the original high strength of the polyester material.

[0070] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. 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.
