Description

Technical Field

[0001] This invention relates to a weft-knitted micro-textured jacquard fabric, its preparation method and application, belonging to the field of textile technology. Background Technology

[0002] Cotton-synthetic filament fabric combines the softness and comfort of cotton fibers with the crispness and wrinkle resistance of synthetic filaments, making it widely used in the apparel industry.

[0003] Currently, cotton-synthetic filament fabrics mainly have the following two weaving methods: One type is the cotton-covered synthetic filament weave (cotton-covered polyester), which uses a weave structure where cotton yarn covers the surface of synthetic filaments, with the synthetic filaments located in the inner layer of the fabric. This weave method offers high cost-effectiveness and good stability, but the fabric surface lacks obvious highlights and texture variations, resulting in a monotonous appearance and a lack of competitive differentiation.

[0004] Another method is the cotton-chemical fiber interweaving method, in which cotton yarn and chemical fiber filaments are interwoven in loops. This method can produce a micro-textured effect on the fabric surface, but because the chemical fiber filaments are displayed on the front of the fabric, there are the following problems: (1) The chemical fiber filaments are easily snagged, causing snagging, which seriously affects the appearance and service life of the fabric; (2) The exposed chemical fiber filaments make the fabric look cheap and not high-end enough, making it difficult to meet the needs of the mid-to-high-end market.

[0005] To address the aforementioned issues, existing technologies have proposed several solutions. For example, CN115323592B discloses a fabric with a connecting layer that prevents snagging, pilling, and fuzzing. This fabric uses high-curvature shrinkage multifilament as the connecting layer and weaves an air-layer structure on a double-sided knitting machine to prevent the exposed synthetic filaments. However, this solution requires a double-sided circular knitting machine, resulting in higher production costs. Furthermore, the double-sided air-layer structure fabric has a relatively high weight and a stiff feel, making it unsuitable for clothing applications requiring softness, comfort, and lightweightness. CN108950840A discloses a cotton-polyester double-sided checkered knitted fabric, also woven on a double-sided weft circular knitting machine. Polyester filaments are still visible on the front side of the fabric, and the weight is relatively high.

[0006] CN113529254A discloses an invisible jacquard knitted fabric, which forms a subtle floral pattern through an integrated knit of the surface and bottom layers. However, the fabric is generally stiff and lacks elasticity, making it difficult to meet the requirements for wearing comfort. CN103603128A discloses a jacquard knitted fabric composed of vertical mesh stripes and flat knitting, which has a rough texture and poor elasticity and resilience.

[0007] Therefore, the existing technology has the following technical problems: under the condition of single-sided circular knitting, it is difficult to simultaneously achieve the complete concealment of chemical fiber filaments on both sides of the fabric, the fabric surface with a micro-textured jacquard effect, and the fabric with multiple functions such as sweat absorption and comfort, moisture wicking and quick drying, anti-snagging and anti-pilling. Summary of the Invention

[0008] To address the aforementioned technical problems, the present invention aims to provide a weft-knitted micro-textured jacquard fabric, its preparation method, and its application. This fabric is woven on a single-sided circular knitting machine, with chemical fiber filaments hidden between the cotton yarns on both the front and back sides, making them invisible on both sides. It exhibits a micro-textured jacquard effect and also possesses multiple functions such as sweat absorption and comfort, quick-drying, anti-snagging, and anti-pilling.

[0009] To achieve the above objectives, the first aspect of the present invention provides a weft-knitted micro-textured jacquard fabric, which uses cotton yarn and chemical fiber filaments as raw materials and is woven on a single-sided circular knitting machine in a four-dye, two-needle cycle. In the first mold: the chemical fiber filaments are looped on both the first and second needles; Second mold: The chemical fiber filaments are gathered on the first needle and looped on the second needle; Third pattern: The cotton yarn forms loops on the first needle and gathers loops on the second needle; Fourth pattern: The cotton yarn forms loops on the first needle and gathers loops on the second needle; The cotton yarn forms the front and back of the fabric, and the chemical fiber filaments are hidden between the cotton yarns on the front and back of the fabric.

[0010] A second aspect of the present invention provides a method for preparing the above-mentioned weft-knitted micro-textured jacquard fabric, comprising the following steps: (1) Weaving: Cotton yarn and chemical fiber filaments are woven in a cyclic pattern on a single-sided circular knitting machine according to the four-dial two-needle weaving method to obtain the greige fabric; (2) Pre-forming: The fabric is pre-formed on a pre-forming machine to obtain a pre-formed fabric; (3) Singeing: The pre-shaped fabric is singeed through a singeing machine to obtain a singeed fabric; (4) Dyeing: The singed fabric is dyed to obtain dyed fabric; (5) Bio-enzyme finishing: The dyed fabric is treated with bio-enzymes to obtain bio-enzyme finished fabric; (6) Drying and shaping: After the bio-enzyme treated fabric is dried, it is shaped on a shaping machine to obtain the weft-knitted micro-textured jacquard fabric.

[0011] The third aspect of the present invention provides the application of the above-mentioned weft-knitted micro-textured jacquard fabric in clothing.

[0012] The present invention has at least the following beneficial effects: This invention employs a specific four-moment, two-needle weaving cycle design. In the first motif, the chemical fiber filaments are looped using two needles to form an intermediate skeleton layer. In the second motif, the chemical fiber filaments are gathered in the first needle and looped in the second, allowing the cotton yarn to partially cover the chemical fiber filaments longitudinally. In the third and fourth motifs, the cotton yarn is looped in the first needle and gathered in the second, creating double-sided coverage of the chemical fiber filaments. This achieves complete concealment of the chemical fiber filaments on both sides of the fabric without the need for a double-sided weave machine, displaying only the cotton yarn on both sides. This solves the snagging problem caused by exposed chemical fiber filaments in traditional cotton-polyester blended fabrics and avoids the heavy weight and stiff feel of double-sided air-layer fabrics. Furthermore, the alternating combination of gathered and looped loops creates a micro-textured jacquard effect on the fabric surface. Compared to traditional cotton-covered polyester plain weave fabrics, this provides a unique, subtly textured feel, enhancing the fabric's competitive advantage. Furthermore, the fabric of this invention has cotton yarn on both the front and back, maintaining the excellent skin-friendliness and moisture absorption of cotton fibers. Meanwhile, the interlayer of synthetic filaments provides moisture-wicking channels, giving the fabric both sweat-wicking comfort and quick-drying properties. This fabric has a single-sided structure, is lightweight, soft to the touch, and features a micro-textured jacquard effect. It also combines multiple functions such as sweat-wicking comfort, quick-drying, anti-snagging, and anti-pilling, resulting in low production costs and suitability for large-scale promotion.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

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.

[0024] According to a specific embodiment of the first aspect of the present invention, the present invention provides a weft-knitted micro-textured jacquard fabric, which uses cotton yarn and chemical fiber filaments as raw materials and is woven on a single-sided circular knitting machine in a four-dye two-needle cycle. In the first mold: the chemical fiber filaments are looped on both the first and second needles; Second mold: The chemical fiber filaments are gathered on the first needle and looped on the second needle; Third pattern: The cotton yarn forms loops on the first needle and gathers loops on the second needle; Fourth pattern: The cotton yarn forms loops on the first needle and gathers loops on the second needle; The cotton yarn forms the front and back of the fabric, and the chemical fiber filaments are hidden between the cotton yarns on the front and back of the fabric.

[0025] like Figure 1 As shown, this invention uses a four-die, two-needle knitting cycle, woven on a single-sided circular knitting machine (with only a lower die, no upper die). The specific knitting process is as follows: First mold: Chemical fiber filaments are fed in, and the first needle forms a loop, the second needle forms a loop. The chemical fiber filaments form complete loops on both needles, constituting the middle layer skeleton of the fabric.

[0026] Second pattern: Chemical fiber filament is fed in, the first stitch gathers the yarn, the second stitch forms a loop. The chemical fiber filament is only padded on the first stitch to form a gather without slipping out of the loop, and then forms a loop normally on the second stitch. Gathering the yarn tightens the chemical fiber filament longitudinally, partially concealing it under the adjacent horizontal rows of cotton yarn loops.

[0027] Third mold: Cotton yarn is fed in, the first stitch forms a loop, and the second stitch gathers the loop. The cotton yarn forms a normal loop on the first stitch, covering the front of the chemical fiber filament loop; the loop gathers on the second stitch, intersecting longitudinally with the chemical fiber filament loop formed by the second stitch of the second mold.

[0028] Fourth pattern: Cotton yarn is fed in, the first stitch forms a loop, and the second stitch gathers the loop. Similar to the third pattern, two consecutive rows of cotton yarn form a loop on the first stitch and gather on the second stitch, creating a double-sided coverage effect on the synthetic filament.

[0029] Through the above weaving method, the synthetic filaments of the first and second motifs are covered by the cotton yarns of the third and fourth motifs from both the front and back sides. On the first stitch, the loops of the third and fourth motifs' cotton yarn cover the loops of the first and second motifs' synthetic filaments; on the second stitch, the loops of the third and fourth motifs' cotton yarn cover the loops of the synthetic filaments on the back side. The final effect is that both the front and back sides of the fabric appear as cotton yarn, with the synthetic filaments sandwiched between the front and back layers of cotton yarn, making them invisible from both sides of the fabric.

[0030] Meanwhile, the alternating combination of gathered and rolled loops creates subtle variations in the fabric surface, resulting in a micro-textured jacquard effect. Different yarn counts and loop lengths can produce different styles of micro-textured effects.

[0031] In some embodiments, the yarn count of the cotton yarn is 26S to 40S.

[0032] In some embodiments, the cotton yarn is spun using methods such as compact spinning, vortex spinning, or Siro compact spinning. Preferably, it is 26S to 40S compact spun cotton yarn.

[0033] In some embodiments, the linear density of the chemical fiber filament is 30D to 150D.

[0034] In some embodiments, the chemical fiber filament includes one or more of polyester filament, high-elastic polyester filament, nylon filament, and spandex filament. Preferably, the chemical fiber filament is polyester filament with an F number of 24 to 72.

[0035] In some embodiments, the fineness ratio of the cotton yarn to the chemical fiber filament is (1.4~2):1. If the fineness ratio is too small (the cotton yarn is too fine or the chemical fiber filament is too coarse), the chemical fiber filament is difficult to be completely covered by the cotton yarn and is easily exposed; if the fineness ratio is too large (the cotton yarn is too coarse or the chemical fiber filament is too fine), the fabric weight increases, and the skeletal support of the chemical fiber filament is weakened. It should be noted that the fineness ratio refers to the ratio of the diameter of the cotton yarn to the diameter of the chemical fiber filament.

[0036] In some embodiments, the length of the 50 loops of the chemical fiber filament is 70-100mm, and the length of the 50 loops of the cotton yarn is 70-100mm. If the yarn length is too short, the fabric is too dense, feels stiff, and lacks elasticity; if the yarn length is too long, the fabric is loose, the chemical fiber filaments are easily exposed, and the microtexture effect is not obvious.

[0037] In some embodiments, the weight of the weft-knitted micro-textured jacquard fabric is 160~260 g / m². 2 .

[0038] A second aspect of the present invention provides a method for preparing the above-mentioned weft-knitted micro-textured jacquard fabric, comprising the following steps: (1) Weaving: Cotton yarn and chemical fiber filaments are woven in a cyclic pattern on a single-sided circular knitting machine according to the four-dial two-needle weaving method to obtain the greige fabric; (2) Pre-forming: The fabric is pre-formed on a pre-forming machine to obtain a pre-formed fabric; (3) Singeing: The pre-shaped fabric is singeed through a singeing machine to obtain a singeed fabric; (4) Dyeing: The singed fabric is dyed to obtain dyed fabric; (5) Bio-enzyme finishing: The dyed fabric is treated with bio-enzymes to obtain bio-enzyme finished fabric; (6) Drying and shaping: After the bio-enzyme treated fabric is dried, it is shaped on a shaping machine to obtain the weft-knitted micro-textured jacquard fabric.

[0039] In some embodiments, in step (1), the single-sided circular knitting machine is a 16G30''~24G30'' single-sided circular knitting machine equipped with a positive yarn feeding device.

[0040] In some embodiments, the conditions for pre-forming in step (2) include: a temperature of 185~195℃, a machine speed of 20~30m / min, an overfeed of 15~40%, and a width of 137~172cm. By controlling the pre-forming temperature within the above range, weaving internal stress can be eliminated, fabric dimensions can be stabilized, and subsequent singeing and dyeing processes can proceed smoothly. If the pre-forming temperature is too low, weaving internal stress cannot be eliminated; if it is too high, excessive shrinkage of the chemical fiber filaments will affect the fabric's feel. The pre-forming can be performed once.

[0041] In some embodiments, in step (3), the singeing is double-sided singeing, with conditions including a temperature of 1300~1400℃ and a speed of 70~90m / min. By controlling the singeing conditions within the above range, high-temperature and rapid passing through the machine causes the surface of the chemical fiber filaments to slightly melt and harden, playing a supporting and skeletal role in the middle layer of the fabric, further reducing the risk of the chemical fiber filaments being snagged, while giving the fabric a crisp feel. If the singeing temperature is too low, the surface modification of the chemical fiber filaments will be insufficient, and the anti-snagging effect will not be obvious; if the singeing temperature is too high or the speed is too slow, it may damage the cotton yarn. In addition, singeing can also remove the fuzz on the surface of the fabric, improving the smoothness of the fabric surface.

[0042] In some embodiments, in step (4), the synthetic fiber filaments are dyed first (which can be referred to as polyester dyeing), and then the cotton yarn is dyed (which can be referred to as cotton dyeing). Preferably, the dyeing is performed using a liquid flow dyeing machine. Dyeing is preferably performed using a liquid flow dyeing machine to reduce damage to the fabric and reduce the generation of creases.

[0043] In some embodiments, the amount of bio-enzyme used in step (5) is 1.0~2.0 g / L. Bio-enzyme treatment can remove microfibers on the surface of cotton fibers, reducing pilling. In addition, to ensure better appearance and physical properties, it is preferable to use bio-enzymes from conventional cotton fabrics. In a preferred embodiment of the present invention, both the front and back of the fabric are tightly spun cotton yarns, and have undergone bio-enzyme finishing, reducing fuzz from the source; the chemical fiber filament skeleton structure of the middle layer restricts the slippage and extraction of cotton fibers, and the three work together to give the fabric superior anti-pilling performance.

[0044] The above-described preparation process effectively solves the problem that the fabric of this invention is prone to creases during production due to its structure, thus enabling the fabric to achieve excellent overall performance.

[0045] According to a specific embodiment of the third aspect of the present invention, the present invention provides the application of the above-described weft-knitted micro-textured jacquard fabric in clothing.

[0064] In the pre-forming step, the blank is stretched by 5% and then fed into the pre-forming machine along the grain direction. The pre-forming conditions include: temperature of 185℃, machine speed of 20m / min, overfeed of 15~20%, width of 150~155cm, and one pass.

[0065] In the double-sided singeing step, the pre-shaped fabric is fed into the singeing machine along the grain direction, with a passing temperature of 1300~1400℃ and a speed of 80m / min.

[0082] The remaining steps are the same as in Example 1.

[0083] The comparative example prepared a cotton-polyester interwoven single-sided fabric, the actual image of which is shown below. Figure 4 As shown. The fabric weight of this comparative example is 220 g / m². 2 .

[0084] Comparative Example 2

[0085] It is woven on a double-sided circular knitting machine using 50S / 1 cotton yarn and 75D / 36F polyester yarn (fineness ratio of 1.19:1), with eight-die cycles and upper and lower discs working together. Figure 5 As shown, the weaving cycle parameters are as follows: First mold: The upper and lower coils are formed into loops in sequence, using 50S / 1 cotton yarn with a yarn length of 103mm (50 loops, as in the following text); Second mold: The lower and upper plates are formed into circles in sequence, using 50S / 1 cotton yarn with a yarn length of 103mm; Third mold: The upper and lower coils are formed into circles in sequence, using 75D / 36F polyester yarn with a yarn length of 97mm; Fourth mold: The lower and upper coils are formed in sequence, using 50S / 1 cotton yarn with a yarn length of 103mm; Fifth mold: The upper and lower coils are formed into circles in sequence, using 75D / 36F polyester yarn with a yarn length of 97mm; Sixth mold: The lower and upper coils are formed in sequence, using 75D / 36F polyester yarn with a yarn length of 97mm; Seventh mold: The upper and lower coils are formed in sequence, using 50S / 1 cotton yarn with a yarn length of 103mm; Eighth mold: The lower and upper coils are formed in sequence, using 75D / 36F polyester yarn with a yarn length of 97mm.

[0088] Test Example 2

[0089] The fabrics of Example 1 and Comparative Examples 1-2 were tested for shrinkage, pilling, snagging, and moisture-wicking properties. The results are shown in Table 5.

[0090] Table 5

[0091] Shrinkage was tested according to the method in GB / T 8630. Pilling was tested according to the method in GB / T 4802.2. Snagging was tested according to the method in GB / T 11047. Moisture-wicking and quick-drying properties were tested according to the method in GB / T 21655.2.

Comparative Example 1 (cotton-polyester blended single-sided fabric) has poor pilling and snagging performance and high shrinkage rate because the polyester filaments are visible on the front side of the fabric. Comparative Example 2 (cotton-polyester blended double-sided fabric) has poor moisture absorption and quick-drying function due to its double-sided air layer structure, and abnormal elongation of lateral shrinkage.
