Description

Technical Field

[0001] This invention relates to a multi-faceted knitted twill fabric that mimics woven fabric, belonging to the field of textile fabric technology. Background Technology

[0002] In the textile fabric industry, with the upgrading of consumer demand, people's expectations for weft-knitted fabrics have shifted from basic reusability to a combination of wearing comfort and functional versatility. While retaining the inherent advantages of knitted fabrics such as softness, breathability, and close-fitting comfort, people are pursuing fabrics with a texture and visual effect similar to woven fabrics.

[0003] Currently, there are two main technical approaches to achieving a woven-like appearance. One approach involves directly using woven fabrics and improving their feel and elasticity through fiber modification or finishing processes. Woven fabrics are inherently stable, smooth, drape well, and highly abrasion-resistant, but their weave structure results in a stiffer feel, poor fit, and lower breathability compared to knitted fabrics. Even with the addition of high-elasticity, high-shrinkage fibers to achieve some elasticity, they generally lack the feel of cotton, and the elasticity is mostly unidirectional or bidirectional, lacking multidirectional elasticity. The other approach involves simulating the woven appearance on weft-knitting equipment through simple changes in the weave structure. However, this method often only achieves texture imitation in a single direction, making it difficult to balance fabric smoothness and dimensional stability.

[0004] It is evident that existing technological solutions present an inherent contradiction at the fabric structure level in simultaneously achieving a woven-like appearance and maintaining the comfort of knitted fabrics. Woven fabrics, limited by their tightly interwoven warp and weft structure, struggle to fundamentally overcome their constraints of stiffness and insufficient multi-directional elasticity. Conversely, conventional weft-knitted woven-like solutions, in pursuing a smooth surface and realistic texture, easily sacrifice the softness and breathability inherent in knitted fabrics. Therefore, there is an urgent need to find a new fabric structure solution that, starting from the fabric structure itself, combines the appearance of woven fabrics with the comfort characteristics of knitted fabrics. This solution must retain the advantages of knitted fabrics such as softness, breathability, and multi-directional elasticity while achieving a smooth surface, clear texture, and crisp drape, creating a woven-like visual effect that meets the market's higher demands for a fusion of fabric functionality and comfort.

[0013] Secondly, the present invention provides a production process for the aforementioned woven-look knitted multi-faceted twill fabric, comprising the following steps: S1, Material Selection: The terry yarn is made of combed compact spun cotton staple fiber, and the ground yarn is made of polyester filament and elastic spandex filament. S2, Weaving: According to the needle arrangement diagram and cam configuration diagram, place the corresponding level of needles and cams on the weft knitting single-sided circular knitting machine, input the target yarn length value, and the yarn enters the knitting area under tension control. The needles knit into loops and interlock with each other under the control of the cam track. The greige fabric is curled downwards or swung by the pulling mechanism, so that the terry yarn forms a terry structure composed of loops and floats. The ground yarn uses full needle plain knitting to lock the previous path to form a twill structure. S3, Pretreatment: The fabric is refined and desized using a refining agent at a temperature below 85℃; S4, dyeing: Disperse dyes are selected and dyeing is carried out in a sodium acetate buffer dye bath with a stable pH of around 5. After dyeing, reduction washing is performed to remove the floating color. S5, Setting: The dyed fabric is set under low tension conditions for 30 to 60 seconds.

[0014] Advantages and effects of the present invention: This invention addresses the technical contradictions in existing woven-style fabric solutions, such as the stiff hand feel, insufficient multi-directional elasticity, and lack of cotton-like texture in woven fabrics, while conventional weft-knitted woven-style solutions struggle to balance fabric smoothness, texture clarity, and dimensional stability. Through a systematic innovation involving a three-dimensional composite yarn system of combed compact cotton staple fiber, T8 polyester fiber, and elastic spandex, a reverse-side design of loop and float composite weave, high-gauge weft-knitted single-sided circular knitting, and low-temperature, low-tension finishing, this invention achieves a new type of fabric that combines the appearance of woven twill with the softness, breathability, and multi-directional elasticity of knitted fabrics. It retains the inherent comfort advantages of knitted fabrics while providing a smooth surface, clear texture, and crisp drape, mimicking the visual effect of woven fabrics. Specifically, it also includes: 1. A composite weave combining loop and float yarns, worn on the reverse side, achieves a woven twill appearance from the very foundation of the knitting structure: An innovative composite weave is used, alternating between loops and floats in terry yarn. The ground yarn is secured with full-stitch plain knit to form a twill weave, with the two weaves forming a complete loop row. The floats move regularly to the left or right within each row, naturally creating a clear and smooth twill texture on the reverse side of the fabric. Using this reverse side as the wearing side gives the fabric a style and drape highly similar to woven twill, while retaining the inherent softness and breathability of knitted fabrics. This breaks down the inherent boundaries between woven and knitted fabrics at the structural level.

[0015] 2. A ternary composite of combed compact cotton staple fiber, T8 polyester fiber, and elastic spandex yarn achieves a synergistic balance between cotton-like feel and multi-directional elasticity: Combed compact cotton staple fiber provides the terry yarn with a natural cotton feel and moisture-wicking breathability, while T8 polyester fiber and elastic spandex yarn form the ground yarn, creating a high-elasticity skeleton. Through the synergistic effect of the high-elasticity, high-shrinkage yarn and spandex in the yarn structure, the fabric exhibits excellent elastic recovery performance in the warp, weft, and twill directions, forming a multi-directional elastic effect. Simultaneously, by controlling the loop length and proportion of the high-elasticity, high-shrinkage yarn and cotton yarn, the fabric achieves a natural cotton-like feel while maintaining high elasticity, solving the problems of traditional elastic fabrics' rough feel and strong plastic texture.

[0016] 3. Precise control of loop length and finishing processes effectively solves the dimensional stability problem of high-elasticity fabrics: By precisely setting the loop length range of terry yarn, polyester fiber, and elastic fiber, and combining this with the coordinated finishing processes such as low-temperature refining and desizing, sodium acetate buffer bath dyeing, reduction washing, and low-temperature low-tension setting, the fabric shrinkage rate is stably controlled within 5%. While giving the fabric high elasticity, this ensures the long-term stability of garment dimensions, solving the common industry problem of high-elastic knitted fabrics being prone to shrinkage and deformation.

[0017] 4. High-gauge circular knitting machines with precision weaving and compact spinning processes ensure smooth fabric surface and high-density quality: High-gauge single-sided circular knitting machines with needle pitches ranging from 18G to 44G are used for weaving, achieving high-density fabric weaving and resulting in a tighter and finer fabric surface. Simultaneously, the terry yarn uses combed compact spun cotton staple fibers, significantly reducing surface hairiness through compact spinning technology, making the fabric surface smoother and improving its appearance and suitability for outerwear. For high-gauge, high-gauge operations, the yarn enters the knitting zone under tension control, effectively reducing fly waste and protecting the loop-forming components, ensuring the stability of mass production processes.

[0018] 5. Diverse weave textures and adjustable weight and width to meet flexible adaptations to different seasons and dressing scenarios: This invention provides various fabric weave structures such as 3-segment left twill, 4-segment left twill, 3-segment right twill, 4-segment right twill, herringbone, plain weave, and random serrated weave, enriching the visual expressiveness of the imitation woven style. By adjusting the thickness of the raw materials, the fabric weight can fluctuate within the range of 140g / m² to 400g / m². By adjusting the machine model and needle size, the cut width can vary within the range of 130cm to 200cm, flexibly meeting the differentiated needs for fabric weight, width, and elasticity for different seasons and dressing scenarios, from light summer clothing to thick autumn and winter coats.

[0035] In a first aspect, the present invention provides a knitted multi-faceted twill fabric that mimics woven fabric. The knitted multi-faceted twill fabric is woven on a weft knitting single-sided circular knitting machine and includes terry yarn and ground yarn. The terry yarn and the ground yarn are woven together in two directions to form a complete loop row. The terry yarn forms a terry structure composed of loops and floats. The ground yarn is formed by locking the previous row with full needle plain knitting to form a twill structure. The terry yarn is combed compact spun cotton staple fiber, and the ground yarn includes T8 polyester fiber and elastic spandex yarn.

[0036] The spinning methods for short fibers can include ring spinning, compact spinning, Siro spinning, compact Siro spinning, air-jet spinning, vortex spinning, etc. They can also contain functional components. The raw material specifications can be 16S-60S, and they can account for 25%-60% of their fabric composition.

[0037] The short fiber composition can be cotton, linen, silk, wool, viscose, acetate, polyester, etc., with two or three of them blended together.

[0038] Polyester elastic fibers can be spun using POY, ATY, DTY, FDY, or a combination of any one or two of these methods. Polyester composite yarns can be composed of a single component, such as PET, PBT, or PTT fibers, or a two-component blend, where the two components can be PET / PBT, PBT / PTT, or PTT / PET. They can also contain functional components, and their raw material specifications can range from 30D to 200D, accounting for 25% to 65% of their composition in fabrics. Elastic fibers include, but are not limited to, PET, PBT, PTT, T8, T400, T800, SORONA, and various compositions of polyester, nylon, polypropylene, and bio-based filament fibers.

[0039] The fabric structure includes imitation woven 3-segment needle left twill fabric structure, imitation woven 4-segment needle left twill fabric structure, imitation woven 3-segment needle right twill fabric structure, imitation woven 4-segment needle right twill fabric structure, imitation woven 3-segment needle herringbone fabric structure, imitation woven 4-segment needle herringbone fabric structure, imitation woven 3-segment needle twill plain weave fabric structure, or imitation woven 3-segment needle random pattern toothed weave fabric structure. In some embodiments, the elastic spandex yarn can be 20D-105D, accounting for 3%-25% of the fabric. The loop length of the terry yarn is 7cm / 99G to 18cm / 99G, the loop length of the polyester fiber in the ground yarn is 16cm / 99G to 40cm / 99G, and the loop length of the elastic fiber is 7cm / 99G to 13cm / 99G. The needle pitch of the weft-knitted single-sided circular knitting machine is 18G to 44G, the cylinder diameter is 26 inches to 34 inches, the weight of the knitted fabric is 140g / m² to 400g / m², and the cut width is 130cm to 200cm. Additionally, the 18G-30G model is suitable for everyday home or work commuting fabrics, while the 32G-44G high-quality model is suitable for high-quality business fabrics.

[0040] Secondly, the present invention provides a production process for the aforementioned woven-look knitted multi-faceted twill fabric, comprising the following steps: S1, Material Selection: Terry yarn often uses pure combed cotton short yarn, which makes the pattern clear and the hair less; the ground yarn usually uses high-strength polyester filament, which makes the fabric base tight and flat, forming a skeleton; the filling yarn in the ground yarn is made of elastic spandex yarn with good wear resistance and tensile recovery. Although polyester does not contain natural impurities, the fabric is a cotton-polyester blend, so pretreatment is still crucial. First, impurities such as machine oil, sizing agents, waxes, and cottonseed hulls applied during weaving are removed to provide a foundation for even dyeing, allowing the dye to penetrate the fibers evenly, avoiding uneven coloring and the formation of streaks, and significantly reducing batch variations, end-to-end variations, and left-to-right color differences. Then, a highly efficient refining agent is used to thoroughly treat the fabric at approximately 85°C for refining and desizing.

[0041] S2, Weaving: According to the needle arrangement diagram and cam configuration diagram, place the corresponding level of needles and cams on the weft knitting single-sided circular knitting machine, input the target yarn length value, and the yarn enters the knitting area under tension control. The needles knit into loops and interlock with each other under the control of the cam track. The greige fabric is curled downwards or swung by the pulling mechanism, so that the terry yarn forms a terry structure composed of loops and floats. The ground yarn uses full needle plain knitting to lock the previous path to form a twill structure. S3, Pretreatment: The fabric is refined and desized using a refining agent at a temperature below 85℃; S4, dyeing: Disperse dyes are selected and dyeing is carried out in a sodium acetate buffer dye bath with a stable pH of around 5. After dyeing, reduction washing is performed to remove the floating color. Choose disperse dyes with good lifting power and uniformity. This high-performance fabric has extremely high requirements for color fastness. Special high-denier filaments need to be dyed at low temperatures, as high temperatures will destroy the perfect macromolecular chain structure formed by super-stretching. It is also necessary to extend the heat preservation time. The pH value of the dye bath is kept stable at around 5, and a sodium acetate buffer system is used to maintain it. Strictly control the cooling rate at 1°C / min (e.g., first cool quickly to 80°C, and then slowly cool to below 50°C before removing from the vat).

[0042] S5, Setting: The dyed fabric is set under low tension conditions for 30 to 60 seconds; after dyeing, a thorough reduction wash is performed to remove loose dye and improve color fastness; the setting time is generally 30-60 seconds; setting under low tension conditions aims to obtain stable dimensions, desired style, and necessary functionality; in terms of fabric requirements, hydrophilic finishing and hand feel finishing are performed.
