Description

[Technical Field]

[0001] The present application relates to the field of textiles, and in particular to new types of textiles. [Background technology]

[0002] Woven fabrics are made by interweaving warp and weft threads according to a specific weave structure. By designing various weave structures, woven fabrics can express a variety of patterns and effects, and achieve a variety of wearing experiences. As people's lifestyles change, their pursuit of clothing is not limited to simple design; especially in denim clothing, there is an increasing pursuit of comfort and style. Traditional denim fabrics are characterized by being thick, heavy, and compact. After weaving thick warp and weft threads, finishing treatments and washing processes (physical and chemical methods) are carried out to create a variety of unique styles.

[0003] Innovations in weaving technology have led to the use of elastic yarns in denim fabrics. Interweaving elastic weft and warp yarns results in elastic denim fabrics that are extremely comfortable to wear. Denim fabrics require a finishing process. Core-spun elastic weft yarns are typically used as the elastic weft yarns. Elastic weft yarns tend to shrink during the finishing process, causing the warp yarns to compress and bulge locally. As a result, the surface of the denim fabric loses its distinct pattern and becomes rough. Furthermore, the resulting denim fabrics have a high shrinkage rate. When used as denim clothing and washed, they undergo significant water shrinkage, leading to quality issues such as dimensional instability and wrinkling. Furthermore, when worn for extended periods or stretched, some areas subjected to greater stress may fail to return to their original position due to stretch recovery fatigue, resulting in swelling issues, which significantly impact the appearance of the denim fabric.

[0004] Therefore, there is still room for improvement and development in the prior art. Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above-mentioned drawbacks of the prior art, the present application aims to provide a new type of woven fabric to solve the problem that the pattern of the conventional elastic denim fabric becomes unclear after finishing treatment. [Means for solving the problem]

[0012] In the new type of woven fabric, when the warp yarns include the surface yarns and the separating yarns, the surface yarns of the warp yarns are inelastic yarns, and the separating yarns of the warp yarns are elastic yarns.

[0013] In the new type of woven fabric, when the weft yarn includes the surface yarn and the separating yarn, the surface yarn of the weft yarn is an inelastic yarn, and the separating yarn of the weft yarn is an elastic yarn.

[0014] In the new type of woven fabric, when the surface yarn and the separating yarn are included only in the warp yarn, the surface yarn and the weft yarn of the warp yarn adopt a 3 / 1 right twill weave structure, and the separating yarn and the weft yarn of the warp yarn adopt a 1 / 1 plain weave structure.

[0015] In the new type of woven fabric, the surface layer yarn is a yarn processed using short fibers or an elastic composite yarn. The elastic composite yarn is a yarn having an elastic fiber core yarn and short fibers wrapped around it, and the yarn count of the surface layer yarn is 6 to 40S.

[0016] In the new type of woven fabric, the yarn count of the surface layer yarn is 7 to 26S.

[0017] In the new type of woven fabric, the separating yarn is one or a combination of two or more of a yarn processed using short fibers, a monofilament yarn, a multifilament yarn, and a composite yarn; When the separating thread is a monofilament thread, a monofilament thread having a standard of 40D to 400D is used as the separating thread, When the separating yarn is a multifilament yarn, a single yarn made by twisting together T400 or polyester and nylon is used as the separating yarn, When the separating yarn is a composite yarn, polyester-coated spandex or nylon-coated spandex is used as the separating yarn, and the polyester or nylon specification is 40-300D, and the spandex specification is 20-105D; The separated yarn is a high count yarn processed using short fibers, and has a yarn count of 21 to 80S.

[0018] The beneficial effects are as follows: The new type of woven fabric of the present application is provided with surface yarns and separating yarns through the design of the woven fabric structure, so that the woven fabric has a clear surface pattern and a stable shrinkage rate, and does not have the problem of swelling even when worn for a long period of time or stretched. [Brief explanation of the drawings]

[0020] The present application provides a new type of woven fabric, and in order to make the objectives, technical solutions and effects of the present application clearer and more explicit, the present application will be described in more detail below. It should be understood that the specific examples described herein are for the purpose of illustrating the present application, but are not intended to limit the present application.

[0021] Explanation of related terms Minimum weave cycle: The unit formed when the pattern of the warp and weft floating points going up and down goes around once is called a complete weave or minimum weave cycle. When the warp threads (weft threads) change from a floating state to a submerged state, or from a submerged state to a floating state, the warp threads and weft threads must cross each other once, and this becomes the crossing point.

[0022] Finished product density is expressed as the number of threads per inch (2.54 cm).

[0023] S is the English count, S=L / (G*840), where G is the weight of the yarn in pounds and L is the length of the yarn in yards.

[0024] D is an abbreviation for denier, a unit that indicates the fineness of synthetic fibers, where D=5315 / S.

[0025] The present application provides a new type of woven fabric formed by interweaving warp yarns and weft yarns, wherein the warp yarns include surface yarns and separating yarns, or the weft yarns include surface yarns and separating yarns, The English count of the separating yarn is larger than that of the surface yarn, and is more than 1 and less than 8 times. At least one of the surface yarn and the separation yarn is an elastic yarn, When the warp yarns include surface yarns and separation yarns, in each minimum weaving cycle formed by the warp yarns and weft yarns, the number of interweaving points formed by interweaving the separation yarns of the warp yarns with the weft yarns is 1 to 7 times, preferably 2 to 6 times, the number of interweaving points formed by interweaving the surface yarns of the warp yarns with the weft yarns, and the number of warp float points formed by interweaving the surface yarns of the warp yarns with the weft yarns is 1 or more times the number of warp float points formed by interweaving the separation yarns of the warp yarns with the weft yarns, When the weft yarn includes a surface yarn and a separation yarn, in each minimum weaving cycle formed by the weft yarn and the warp yarn, the number of interweaving points formed by interweaving the separation yarn of the weft yarn with the warp yarn is 1 to 7 times, preferably 2 to 6 times, the number of interweaving points formed by interweaving the surface yarn of the weft yarn with the warp yarn, and the number of weft float points formed by interweaving the surface yarn of the weft yarn with the warp yarn is at least 1 time the number of weft float points formed by interweaving the separation yarn of the weft yarn with the warp yarn.

[0026] In this invention, a new type of woven fabric is designed, which includes surface yarns and separating yarns. This woven fabric has two types of yarns in the warp or weft direction. By increasing the density of the separating yarns and their interweaving frequency, the number of interweaving points between the separating yarns and the weft or warp yarns increases, resulting in a dense interweaving of the yarns, forming a dense mesh structure in the woven fabric. Since at least one of the surface yarns and separating yarns is an elastic yarn, the woven fabric has a certain degree of stretchability and elastic recovery. Elastic fibers that make up the elastic yarns include, but are not limited to, rubber filaments, bicomponent filaments, and polyurethane.

[0027] In a preferred embodiment of the present application, when the warp yarns include surface layer yarns and separation yarns, the density of the separation yarns in the finished product is 1 to 4 times, and preferably 1 to 2 times, that of the surface layer yarns in the warp yarns. When the warp yarns include surface layer yarns and separation yarns, the density of the separation yarns in the finished product is preferably 60 to 120 threads / inch, and the density of the surface layer yarns in the warp yarns is preferably 60 to 100 threads / inch. By setting the density of the finished product within this range, the separation yarns in the warp yarns and the weft yarns are woven more densely, and the mesh structure formed by the interweaving of the separation yarns in the warp yarns and the weft yarns becomes denser.

[0028] In a preferred embodiment of the present application, when the weft yarn includes a surface layer yarn and a separating yarn, the density of the separating yarn in the finished product is 1 to 4 times, preferably 1 to 2 times, that of the surface layer yarn in the weft yarn. When the weft yarn includes a surface layer yarn and a separating yarn, the density of the separating yarn in the finished product is preferably 30 to 120 ends / inch, and the density of the surface layer yarn in the weft yarn is preferably 30 to 120 ends / inch. By setting the density of the finished product within this range, the separating yarn in the weft yarn and the warp yarn are woven more densely, and the mesh structure formed by the separating yarn in the weft yarn and the warp yarn becomes denser.

[0029] Conventional elastic woven fabrics have a high shrinkage rate in the elastic direction after finishing, typically around -10% to 12%. When processed into denim garments and washed, denim fabrics experience significantly uneven shrinkage, resulting in relatively strong shrinkage in some areas of the fabric's surface, resulting in a lack of a pattern on the surface of the woven fabric or in the yarns on the surface of the woven fabric pressing against each other, blurring the pattern. Furthermore, conventional elastic woven fabrics have a high shrinkage rate, which makes them prone to shrinkage and wrinkles after washing, giving them a soft, collapsed appearance and preventing the three-dimensionality of the woven fabric from being accentuated. In the present invention, the weave structure of the woven fabric is designed to clearly define the pattern on the surface of the woven fabric. In the present invention, the woven fabric layer formed by the surface yarns and the weft and / or warp yarns is the outer surface of the woven fabric, which is used to express the pattern of the woven fabric. The woven fabric layer formed by the separating yarns and the weft and / or warp yarns is usually the inner surface of the woven fabric. Because there are many interweaving points between the separating yarns and the weft and / or warp yarns, the yarns are densely interwoven, forming a dense mesh structure in the woven fabric, which provides support. In the present invention, this mesh structure effectively prevents the fabric from shrinking in the elastic direction during washing after the woven fabric is finished and made into clothing, maintaining the dimensional stability of the woven fabric, stabilizing the shrinkage rate of the woven fabric at a low level, preventing significant shrinkage or uneven shrinkage, and allowing the outer surface of the woven fabric to have a clear pattern. Furthermore, because the degree of shrinkage of the woven fabric layer formed by the separating yarns and the weft and / or warp yarns is smaller than that of the woven fabric layer formed by the surface layer yarns and the weft and / or warp yarns, a small space is formed between the two fabric layers, giving the woven fabric layer formed by the surface layer yarns and the weft and / or warp yarns a three-dimensional feel, and the woven fabric has a three-dimensional effect. In addition, these minute spaces give the woven fabric a relatively comfortable feel, a pleasant touch, and a rich, full texture, effectively solving the problem that conventional elastic woven fabrics are soft and prone to crumbling.

[0030] In the present invention, the weaving structure of the woven fabric is designed to give the woven fabric elastic properties and excellent stretchability and elastic recovery. Because the woven fabric of the present invention has a dense mesh structure, the mesh structure stretches appropriately when stretched, giving the woven fabric a certain degree of stretchability. When the woven fabric is further stretched, the dense mesh structure constrains the yarns, preventing further stretching of the woven fabric, resulting in excellent elastic recovery. Even when worn for long periods of time, excessive stretching of the woven fabric can be prevented, effectively reducing bulkiness.

[0031] Furthermore, in conventional double-layered woven fabrics, when two types of yarns are woven in the same direction, either in the warp or weft direction, the stretching of one yarn suppresses the stretching of the other yarn, but the two types of yarns cannot be prevented from migrating to each other, resulting in one yarn being exposed on the surface of the woven fabric where the other yarn is located. In particular, when the two types of yarns are different colors, the exposure of one yarn on the surface of the woven fabric where the other yarn is located can cause irreparable quality problems. In the present invention, the dense mesh structure formed by interweaving the separating yarn with the weft and / or warp yarns prevents the separating yarn from shifting in position, eliminating the exposure of the separating yarn on the surface of the woven fabric where the surface yarn is located.

[0032] When the warp yarns include surface yarns and separating yarns, the surface yarns of the warp yarns are preferably inelastic yarns, and the separating yarns of the warp yarns are preferably elastic yarns. The surface yarns of the warp yarns can give the woven fabric the style of denim woven fabric, and the separating yarns of the warp yarns can give the woven fabric certain elastic properties, so that the woven fabric has certain elasticity and excellent extensibility in the warp direction.

[0033] When the weft includes a surface layer yarn and a separating yarn, the surface layer yarn of the weft is preferably an inelastic yarn and the separating yarn of the weft is preferably an elastic yarn. The separating yarn of the weft can mainly provide the woven fabric with excellent elasticity and extensibility, and can also form a dense mesh structure, so that the woven fabric is less likely to develop quality defects such as deformation or swelling due to elongation over a long period of time.

[0034] In the present invention, the new type of woven fabric preferably has warp yarns including surface yarns and separating yarns, and the woven fabric layer formed by the warp surface yarns and weft yarns is the outer surface of the woven fabric and is used to express the pattern of the woven fabric, so that the direction of the warp yarns of the woven fabric expresses the style of traditional denim fabric, effectively reduces the basis weight of the woven fabric, and gives the woven fabric a three-dimensional feel.

[0035] In a preferred embodiment of the present invention, when only the warp yarns include surface yarns and separating yarns, the surface warp yarns and weft yarns adopt a 3 / 1 right twill weave structure, and the separating warp yarns and weft yarns adopt a 1 / 1 plain weave structure. The dense structure formed by the separating warp yarns and weft yarns provides the woven fabric with a certain stretch effect, providing a comfortable wearing experience and a certain resistance during continuous stretching, ensuring the dimensional stability of the woven fabric during wear and preventing quality issues such as bulkiness even after long-term wear. Furthermore, because the separating warp yarns are covered, the dense structure formed by the separating warp yarns and weft yarns is hidden, resulting in a clear pattern on the surface of the woven fabric.

[0036] In the present invention, the woven fabric layer, formed by the surface layer yarns and the weft and / or warp yarns, is the outer surface of the woven fabric and is used to express the pattern of the woven fabric. Furthermore, the surface layer yarns may be yarns processed using staple fibers or elastic composite yarns, and the elastic composite yarns are yarns in which an elastic fiber is used as a core yarn and is covered with staple fibers. Staple fibers include, but are not limited to, one or a combination of two or more of cotton, linen, wool, silk, polyester, Tencel, modal, etc. Elastic fibers include, but are not limited to, one or a combination of two or more of polyurethane, rubber filament, polyolefin, etc. In the present invention, staple fibers refer to fibers having a length of 1 cm to 10 cm.

[0037] Preferably, the yarn count of the surface layer yarn is 6 to 40S, more preferably 7 to 26S, which allows the style of the denim fabric to be better expressed.

[0038] Furthermore, the separating yarn may be one or a combination of two or more of yarns processed using staple fibers, monofilament yarns, multifilament yarns, and composite yarns. Staple fibers include, but are not limited to, one or a combination of two or more of cotton, linen, wool, silk, polyester, Tencel, modal, etc.

[0039] Monofilament yarns are single yarns formed by twisting or not twisting filaments such as polyester or nylon. Separable yarns can be monofilament yarns with a standard of 40D to 400D, preferably 75D to 300D. Separable yarns of this standard can impart a certain force to woven fabrics and prevent them from stretching.

[0040] Multifilament yarns are single yarns formed by twisting or not twisting two or more filaments, such as T400, or single yarns formed by twisting together polyester and nylon.

[0041] Composite yarn generally refers to core-spun yarn, a new yarn made by combining two or more fibers, such as cotton-coated spandex, polyester-coated spandex, or nylon-coated spandex. The separating yarn may be polyester-coated spandex or nylon-coated spandex, with the polyester or nylon having a specification of 40-300D and the spandex having a specification of 20-105D. The use of separating yarns of this specification can impart a certain degree of elasticity to woven fabrics, but the outer layer of polyester or nylon acts as an inhibitor, making the fabric less stretchable, resulting in excellent elastic recovery.

[0042] Furthermore, the separated yarn is preferably a high count yarn processed using short fibers, and the yarn count is 21 to 80S.

[0043] The woven fabric of the present application can be woven using an existing loom, and the weaving method is conventional and will not be described in detail here.

[0044] When the warp consists of surface yarns and separating yarns, two systems of yarns exist in the warp direction, and so weaving requires a loom with two warp beams. By providing two different warp beams, one for the surface yarns and one for the separating yarns, it is generally possible to place the warp beam for the surface yarns at the bottom of the loom and the other for the separating yarns at the top. The surface yarns and separating yarns are unwound from their respective warp beams, and the yarns pass through the dropper, heald, reed, and swing-back beam in that order, where they are interwoven with the weft yarns by controlling the tension, forming a woven fabric that is then wound onto a cloth roll.

[0045] When the weft is composed of a surface yarn and a separate yarn, two types of weft exist in the direction of the weft, and the surface yarn and the separate yarn are used as wefts in the loom, and the weft insertion is performed sequentially, and the yarns are introduced into the woven fabric one by one each time the reed is beaten. Alternatively, two wefts can be introduced simultaneously, and in the beating process, the two types of yarns are sent out simultaneously on the same plane, and the two wefts are clamped by the rapier clamp of the loom and sent out simultaneously, so that they are woven interlaced with the warp yarns.

[0046] The present invention will be further described below with reference to specific examples.

[0047] Example 1 The warp threads consist of surface threads (thread A) and separation threads (thread B). Warp threads: The surface threads (thread A) are pure indigo blue 10S pure cotton threads.
