Abstract

This invention discloses a roving-count ribbed corduroy-like woven fabric and its preparation method, belonging to the field of woven fabric technology. The fabric is woven from warp and weft yarns, both of which are single-system yarns. The fabric's structure includes plain weave and ribbed weave. The ribbed weave forms raised grooves on the fabric surface, while the plain weave forms the intervals between these grooves. The warp yarns forming the ribbed weave are roving, and the warp yarns forming the plain weave are fine yarns, with the fine yarn count being 1.5 to 2.5 times that of the roving. This invention, by designing an alternating arrangement of plain weave and ribbed weave, and utilizing the roving characteristics of the warp yarns in the ribbed weave, combined with a napping process, directly forms abundant pile on the grooves created by the ribbed weave, achieving a soft hand feel. This solves the problems of complex production processes and high costs in existing technologies, as well as the quality problems of traditional corduroy fabrics such as shedding, low strength, and poor tearing.

Description

Technical Field

[0001] This invention relates to a woven fabric with raised stripes resembling corduroy and its preparation method, belonging to the field of woven fabric technology. Background Technology

[0002] Corduroy fabric, with its unique ribbed structure and full pile appearance, has long been widely used in clothing, home décor, and other fields. Traditional corduroy fabric is a weft-pile fabric, and its production method is complex, usually employing a double-weft or double-layer weaving method. Specifically, its weft direction requires two systems of yarns: ground weft (which interweaves with the ground warp to form the base fabric) and pile weft (which forms the main body of the pile). During the weaving process, the pile weft exists on the fabric surface as long floats. Subsequently, a pile-cutting process is required to cut these long floats along the warp direction. Then, a brushing process (using a wire brush or quilling roller to brush the pile multiple times) is used to make the cut pile stand up and fluffy. Finally, a singeing / smoothing process (using a flame or hot plate to sweep across the pile surface) is used to burn off the irregular long pile, making the pile surface smooth and with a soft luster.

[0003] This traditional production process has many shortcomings: First, the weaving process is complex, requiring two sets of weft yarn systems, which increases yarn costs and production difficulty; second, the cutting process not only requires specialized equipment but also wastes yarn, and the pile after cutting has poor holding power and is easy to fall off, resulting in "pilling" during the use of the fabric; in addition, because cutting damages the yarn structure, the overall strength of the fabric will decrease, and it is prone to quality problems such as tearing (i.e., slippage of warp and weft yarns), affecting the durability of the fabric.

[0004] To overcome the above problems, some improvements have been made in the existing technology. For example, CN110485167A discloses a warp-knitted corduroy-like fabric preparation process, which forms a surface layer through warp knitting and then laminates a napped underlayer to simulate the corduroy effect. However, this method involves multiple processes such as warp knitting and lamination, and the process is still relatively complex. Another example is CN110685051A, which discloses a striped corduroy fabric. It uses colored chenille yarn as the pile warp and weft yarn to form the pile section. Although it does not require pile cutting, the chenille yarn itself has a pile-like structure, and the resulting striped effect still differs from the tightly ribbed structure of traditional corduroy, and the production cost is relatively high.

[0005] Therefore, developing a corduroy-like fabric that is simple to produce, low in cost, and can effectively solve the quality problems of traditional corduroy fabrics such as shedding, low strength, and poor tearing is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The present invention aims to provide a roving-count ribbed corduroy woven fabric and its preparation method, in order to solve the problems of complex production process and high cost in the prior art, as well as the technical problems of traditional corduroy fabrics such as shedding, low strength and poor tearing.

[0007] To achieve the above objectives, the first aspect of the present invention provides a woven fabric with raised ribs resembling corduroy, the fabric being woven from warp and weft yarns, both of which are single-system yarns; the fabric's structure includes a plain weave and a raised rib weave; the raised rib weave forms raised ribs on the surface of the fabric, and the plain weave weave forms the intervals between the ribs; wherein the warp yarns forming the raised rib weave are rovings, the warp yarns forming the plain weave weave are fine yarns, and the yarn count of the fine yarns is 1.5 to 2.5 times that of the rovings.

[0008] A second aspect of the present invention provides a method for preparing the above-mentioned roving-count ribbed corduroy woven fabric, comprising the following steps: (1) Weaving: On a shuttle loom, warp yarns and weft yarns of a single system are interwoven according to the fabric structure to form a grey fabric; (2) Finishing: The fabric is desized, selectively dried and shaped, napped, shaped and pre-shrinked in sequence to obtain the roving ribbed corduroy woven fabric.

[0009] The present invention has at least the following beneficial effects: The fabric of this invention uses a single-system yarn in both warp and weft directions, eliminating the need for complex double-weft weaves and processes such as pile cutting, thus simplifying the production process and reducing equipment requirements and yarn costs. By designing an alternating plain weave and ribbed weave, and utilizing the roving characteristics of the warp yarns in the ribbed weave, a rich pile is directly formed on the ribbed structure during finishing, achieving a soft hand feel. The pile formed by this method originates from the roving warp yarns constituting the ribs, resulting in a firmly held pile and fundamentally solving the shedding problem caused by pile cutting in traditional corduroy. Simultaneously, by avoiding the damage to the overall fabric structure caused by pile cutting, the fabric of this invention has higher structural stability and better tear resistance, while also improving strength. The final fabric is soft to the touch, with a full pile, clear ribbed effect, and an appearance and feel comparable to traditional corduroy, but with lower production costs and superior quality, making it widely applicable in clothing, home textiles, and home decoration.

[0014] To provide a clearer understanding of the technical features, objectives, and beneficial effects of the present invention, the present invention will now be described in detail below, but this should not be construed as limiting the scope of the invention.

[0015] It should be noted that, unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0016] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this invention can be purchased from the market or prepared by existing methods.

[0017] It should be understood that the terms “comprising,” “including,” and / or “containing” as used herein specify the presence of the stated features, integers, steps, components, or combinations thereof, but do not exclude the presence or addition of one or more other features, integers, steps, components, or combinations thereof.

[0018] The endpoints and any values ​​of the ranges disclosed in this invention are not limited to the precise ranges or values, and these ranges or values ​​should be understood to include values ​​close to these ranges or values. For numerical ranges, the endpoint values ​​of the various ranges, the endpoint values ​​of the various ranges and individual point values, and individual point values ​​can be combined with each other to obtain one or more new numerical ranges, which should be considered as specifically disclosed in this invention.

[0019] The first aspect of the present invention provides a roving-count ribbed corduroy-like woven fabric, the fabric being woven from warp and weft yarns, both of which are single-system yarns; the fabric's structure includes a plain weave and a ribbed weave; the ribbed weave forms raised ribs on the surface of the fabric, and the plain weave forms the intervals between the ribs; wherein the warp yarns forming the ribbed weave are rovings, the warp yarns forming the plain weave are fine yarns, and the yarn count of the fine yarns is 1.5 to 2.5 times that of the rovings.

[0020] In this invention, both warp and weft yarns use a single-system yarn, and are constructed using plain weave and rib weave (such as...). Figure 1As shown) this gives the fabric the ribbed effect of traditional corduroy (as shown). Figure 2 (As shown). The warp yarns of the plain weave are fine yarns, while the warp yarns of the ribbed weave are roving. By controlling the yarn count of the fine yarn to be 1.5 to 2.5 times that of the roving, and combining this with the napping process in the finishing stage, the fabric of this invention can achieve the same rich pile characteristics as traditional corduroy fabric without the need for pile cutting, resulting in a soft hand feel. This also solves the problems of complex production processes and high costs in existing technologies, as well as the quality problems of traditional corduroy fabrics such as shedding, low strength, and poor tearing. If the yarn count of the fine yarn is less than 1.5 times that of the roving, the difference in yarn thickness between the ribbed and plain weave areas is not significant, making it difficult to form a sufficiently full pile after napping. If it is more than 2.5 times, the yarn in the ribbed area is too thick, which may lead to an excessively rough surface texture, a rough hand feel, and increased weaving difficulty.

[0021] It should be noted that the "warp and weft yarns are both single-system yarns" mentioned in this invention means that during the weaving process, only one type of yarn with one function is used in the weft direction, and there is no need to distinguish between ground weft and pile weft as in traditional corduroy; although the warp direction is composed of yarns with different counts, it participates in the interlacing as a whole as a system, and there is no need to set up an independent pile warp system.

[0022] In some embodiments, the roving has a count of 10 to 30 English count, and the yarn has a count of 20 to 50 English count.

[0023] In some embodiments, the roving includes one or more of the following: cotton yarn, wool, linen, polyester, and viscose.

[0024] In some embodiments, the yarn includes one or more of the following: cotton yarn, wool, linen, polyester, and viscose.

[0025] In some embodiments, the weft yarn has a count of 20 to 50 English count.

[0026] In some embodiments, the weft yarn includes one or more of the following: cotton yarn, cotton yarn covered with spandex elastic yarn, wool, linen, polyester, viscose, polyester covered with spandex elastic yarn, and viscose covered with spandex elastic yarn.

[0027] In some embodiments, the raised stripe structure is composed of continuous warp floats that form raised ribs on the surface of the fabric.

[0028] In some embodiments, the number of warp yarns in the plain weave is 2 to 6, and the number of warp yarns in the ribbed weave is 4 to 8 in one cycle. By controlling the number of warp yarns in the plain weave and ribbed weave within this range, it is beneficial to balance the width and spacing of the ribs, making the texture of the fabric surface clear and uniform, and obtaining a striped appearance that is closer to traditional corduroy.

[0029] In some embodiments, the warp density of the fabric is 100-150 threads / inch, and the weft density is 60-100 threads / inch. Controlling the warp and weft densities within this range helps to reduce weaving difficulty while ensuring the fabric's structural stability. It should be noted that traditional corduroy, due to the need for pile cutting, typically employs a high-density weaving where the weft density is much greater than the warp density (often more than twice the warp density), resulting in high weft insertion resistance and weaving difficulties. In contrast, this invention uses a design where the warp density is greater than the weft density (the warp density is approximately 1.5-2 times the weft density), significantly reducing the weft density, making weft insertion easier, and reducing the number of weft insertions, thereby improving weaving efficiency and reducing downtime issues such as warp and weft breaks.

[0030] In some embodiments, the warp and / or the weft yarns are single-color or multi-color yarns.

[0031] In some embodiments, the warp and / or weft yarns are multicolored yarns, forming a pattern arrangement in the warp and / or weft directions of the fabric. The present invention can use multicolored yarns to form a pattern arrangement in the warp and / or weft directions of the fabric according to the pattern requirements of the fabric, such as striped or checkered patterns.

[0032] A second aspect of the present invention provides a method for preparing the above-mentioned roving-count ribbed corduroy woven fabric, comprising the following steps: (1) Weaving: On a shuttle loom, warp yarns and weft yarns of a single system are interwoven according to the fabric structure to form a grey fabric; (2) Finishing: The fabric is desized, selectively dried and shaped, napped, shaped and pre-shrinked in sequence to obtain the roving ribbed corduroy woven fabric.

[0033] In some embodiments, the preparation method does not include the step of cutting the down.

[0034] In some embodiments, the preparation method does not include the steps of singeing or smoothing.

[0035] In some embodiments, the napping process includes pre-softening and napping steps. The pre-softening process can employ conventional techniques in the art. The napping process conditions include: a machine speed of 20-40 m / min, 1-5 passes, and a cylinder speed of 95-120 rpm. By controlling the napping process conditions within the above range, it is further beneficial to evenly and appropriately pull the nap from the roving warp yarns, forming a dense, full, and upright nap layer, and avoiding loose yarn structure or decreased strength due to excessive napping.

[0036] In some embodiments, the desizing, dry fabric setting, setting, and pre-shrinking processes can employ conventional processes in the art, which can be adjusted according to actual needs. This invention does not impose any special limitations on these processes. Furthermore, for varieties with weft yarns containing spandex elastic yarn, the dry fabric setting step can be performed, while for varieties without spandex elastic yarn, this step can be omitted.

[0037] The preparation method of the present invention does not require additional equipment; it can be produced by weaving on a shuttle loom. Furthermore, the finishing process does not require steps such as cutting and singeing, and it does not involve complex procedures. The process flow is shorter and the equipment requirements are lower, thereby effectively reducing production costs.

[0038] The technical solutions of the present invention are specifically illustrated by the following embodiments, but the present invention is not limited to these embodiments. Of course, various modifications can be made within the scope of the key points of the present invention.

[0039] Example 1

[0040] This embodiment provides a roving, raised-ribbed corduroy-like woven fabric with a warp density of 126 threads / inch and a weft density of 60 threads / inch. Unlike traditional corduroy, which requires doubling the weft density during finishing (due to pile cutting), this fabric does not have the increased complexity of a warp-to-weft density.

[0041] 1. Yarn selection and arrangement: Warp yarns: Comprising two types of yarns, arranged in a cyclical pattern of 2 fine yarns and 4 rovings. Plain weave warp yarns (fine yarns): 30-count cotton yarn. Ribbed weave warp yarns (rovings): 40 / 2-count cotton yarn (two 40S single yarns twisted together, equivalent to a 20-count yarn, coarser than 30-count). The fine yarn count is 1.5 times that of the roving yarn.

[0042] Weft yarn: 20-count / 40D cotton yarn wrapped with spandex elastic yarn (i.e., 20-count cotton yarn wrapped with 40D spandex elastic yarn).

[0043] 2. Organizational Structure Design: like Figure 3 As shown, the fabric structure consists of alternating plain weave and ribbed weave. In this embodiment, in one cycle, the plain weave has 2 warp yarns, and the ribbed weave has 4 warp yarns. 30-count cotton yarn is threaded through 1-2 heddles, and 40 / 2-count cotton yarn is threaded through 3-6 heddles. By lifting the heddles, warp floats are formed, creating the ribbed weave. In the ribbed weave, the warp floats formed by the roving create raised ribs on the fabric surface, and the plain weave forms the intervals between the ribs, such as... Figure 4 As shown.

[0044] 3. Preparation method: Dyeing: The warp 30-count cotton yarn, 40 / 2-count cotton yarn and the weft 20 / 40D cotton-wrapped spandex yarn are dyed separately.

[0045] Pre-weaving preparation: The dyed warp yarns (30 count and 40 / 2 count) are wound into a warp beam in parallel according to the design pattern, and then sized by a sizing machine before being wound into a weaving beam.

[0046] Greige fabric: On an air-jet loom, the warp and weft yarns on the warp beam are interwoven according to the designed weave structure to form the greige fabric. The warp yarns are multi-colored yarns, forming a pattern arrangement in the warp direction of the fabric, such as... Figure 4 As shown.

[0047] Post-editing: Desizing: machine speed 65m / min, formula TJ08 (Guangdong Zhenyuan Textile Technology Co., Ltd.), stacking time 15min, stacking temperature 35℃.

[0048] Dry fabric setting: speed 30m / min, temperature 185℃, upper overfeed 2% / lower overfeed 0%, fixed width 142cm, lower width 140cm.

[0049] Raising and finishing: Pre-softening: machine speed 20m / min, fixed width 142cm, upper overfeed 2% / lower overfeed 0%, temperature 150℃, formula DX332 (Guangdong Zhenyuan Textile Technology Co., Ltd.), width drop 141cm; Roughing: machine speed 30m / min, 4 times, cylinder speed 105rpm.

[0050] Setting parameters: vehicle speed 30m / min, fixed width 143cm, upper overfeed 2% / lower overfeed 0%, temperature 150℃.

[0051] Pre-shrinkage: machine speed 50m / min, fabric shrinkage rate -5%, overfeed / speed ratio -7%, width 139cm, rubber blanket temperature 110~130℃, felt temperature 110℃, top roller pressure 10bar, tension 2bar.

[0052] Example 2

[0053] This embodiment provides a woven fabric with a coarse yarn count and raised stripes, resembling corduroy, with a warp density of 150 threads / inch and a weft density of 90 threads / inch.

[0054] Yarn Selection and Arrangement: Warp: Comprising two types of yarn, arranged in a cyclical pattern of 2 fine yarns and 4 rovings. Plain weave warp (fine yarn): 50-count cotton-Tencel blended yarn (70% cotton, 30% Tencel). Ribbed weave warp (roving): 30-count cotton yarn. The fine yarn count is 1.67 times that of the roving. Weft: 30-count cotton-Tencel blended yarn (70% cotton, 30% Tencel).

[0055] Organizational structure design: In one cycle, the plain weave has 2 warp yarns and the ribbed weave has 4 warp yarns. The rest is the same as in Example 1.

[0056] Preparation method: basically the same as in Example 1, but since the weft yarn in Example 2 does not contain spandex elastic yarn, dry fabric setting is not required.

[0057] Example 3

[0058] This embodiment provides a woven fabric with a coarse yarn count and raised stripes, resembling corduroy, with a warp density of 130 threads / inch and a weft density of 86 threads / inch.

[0059] Yarn selection and arrangement: Warp yarns: consist of two types of yarns, arranged in a cyclic pattern of 2 fine yarns and 4 rovings. Plain weave warp yarns (fine yarns): 50-count cotton yarn. Ribbed weave warp yarns (rovings): 30-count cotton yarn. The fine yarn count is 1.67 times that of the roving yarn. Weft yarns: 30-count cotton yarn.

[0060] Organizational structure design: In one cycle, the plain weave has 2 warp yarns and the ribbed weave has 4 warp yarns. The rest is the same as in Example 1.

[0061] Preparation method: basically the same as in Example 1, but since the weft yarn in Example 3 does not contain spandex elastic yarn, dry fabric setting is not required.

[0062] Comparative Example 1

[0063] This comparative example provides a commercially available traditional cut corduroy fabric. Its warp density is 88 threads / inch and its weft density is 162 threads / inch. The warp yarns are 40-count cotton yarn, and the weft yarns are a combination of 40-count and 32-count cotton yarns, using a double weft structure. The ground weft uses 32-count cotton yarn, and the pile weft uses 40-count cotton yarn, arranged in a 1:2 ratio. During weaving, the pile weft exists on the fabric surface as long floats. The finishing process involves cutting these long floats along the warp direction, followed by a brushing process (multiple brushings with a wire brush or licker-in roller) to make the cut pile stand up and fluffy. Finally, a singeing / flattening process (passing the pile surface with a flame or hot plate) burns off the irregular long fibers.

[0064] Comparative Example 2

[0065] This comparative example provides a warp-knitted composite corduroy-like fabric, the preparation method of which includes the following steps: (1) Preparation of surface fabric: A 32-needle warp knitting machine is used to weave a greige fabric with 50D / 24F polyester FDY as the ground yarn and 100D / 144F polyester DTY as the pile yarn. The greige fabric is prepared by pre-setting, slitting (cutting the pile yarn extension line), brushing, dyeing and setting.

[0066] (2) Preparation of the base fabric: The base fabric is made by using an 18-needle circular knitting machine with 100D / 144F polyester FDY as the face yarn and 100D / 24F polyester DTY as the base yarn. After dyeing, setting and napping, the base fabric is obtained.

[0067] (3) Composite: The smooth surface layer of the top fabric and the bottom fabric are hot-pressed together with PU resin adhesive. The hot-pressing temperature is 100~110℃ and the pressure is 6.0~6.5MPa to obtain warp-knitted composite corduroy fabric.

[0068] Comparative Example 3

[0069] This comparative example provides a corduroy-like fabric, the preparation method of which is basically the same as that of Example 1, the only difference being that the warp yarns in the raised stripe area are the same 30-count cotton yarns as those in the plain weave area, instead of roving. Everything else is the same as in Example 1.

[0070] Comparative Example 4

[0071] This comparative example provides a corduroy-like fabric, the preparation method of which is basically the same as that of Example 1, except that the finishing steps do not include napping, but only desizing, dry fabric setting, setting and pre-shrinking. The rest are the same as in Example 1.

[0072] Test case

[0073] The fabrics prepared in the above embodiments and comparative examples were subjected to performance comparison tests, and the results are shown in Table 1.

[0074] Among them, shedding was tested according to the method in GB / T 45513-2025. Tear strength was tested according to the method in GB / T 21294 (Tear)-2024. Tear strength was tested according to the method in GB / T 3917.1-2009. Tensile strength was tested according to the method in ISO13934-2:2014. Pile fullness was determined by sensory evaluation. Five professional graders evaluated the density, uniformity, and uprightness of the pile on the sample under a D65 standard light source box, taking the average value and classifying it into 1-5 levels, where level 1 indicates sparse and uneven pile, and level 5 indicates full, uniform, and upright pile.

[0075] Table 1. Comparison Test Results of Fabric Performance

[0076] As shown in Table 1, the fabrics of Examples 1-3 of this invention are significantly superior to traditional cut corduroy fabrics (Comparative Example 1) in terms of shedding, breaking strength, and tear resistance, and also achieve excellent pile fullness. Compared with warp-knitted composite imitation corduroy fabric (Comparative Example 2), the fabric of Example 1 of this invention has better shedding, higher strength, and a simpler preparation process, requiring no complex processes such as warp knitting and composite. Comparative Example 3, because the raised rib section uses the same fine yarn (30 count) as the plain weave section, failed to create a difference in yarn thickness. During the finishing process, it was difficult to form sufficiently full pile in the rib area, resulting in only a slight fuzzy feel on the fabric surface, failing to simulate the typical pile effect of corduroy. Although Comparative Example 4 has a clear rib structure, because it was not finished, the rib surface is smooth and without pile, far removed from the appearance and feel of traditional corduroy. This proves that the synergistic effect of finishing and the raised rib yarn structure is a key step in forming a pile effect, and neither can be omitted.

[0077] In summary, the roving-count embossed corduroy-like woven fabric and its preparation method of the present invention, through ingenious structural design (combination of plain weave and embossed stripes) and raw material matching (roving yarn for embossed stripes and fine yarn for plain weave, with the fine yarn count being 1.5 to 2.5 times that of the roving yarn), combined with specific finishing processes (pile finishing), successfully produces a fabric with an appearance and feel comparable to traditional corduroy, and superior internal quality (resistance to shedding, strength, and tear resistance) under a simplified process that eliminates the need for pile cutting. It has high industrial application value and market prospects.

[0078] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
