[0001] This utility model relates to the field of knitted fabric technology. More specifically, it relates to a weft-knitted fabric. Background Technology

[0002] Currently, weft-knitted cotton spandex jersey fabric has a simple structure and is relatively lightweight. It is a widely used type of weft-knitted fabric in summer clothing. However, it has poor shape retention, coarse yarns have a poor hand feel, and high yarn strength is not ideal. Utility Model Content

[0003] In view of the above problems, one object of this utility model is to provide a weft-knitted fabric with good skin-friendly, breathable, moisture-absorbing and shape-retaining properties.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A weft-knitted fabric, comprising:

[0006] The first yarn and the second yarn are arranged alternately in sequence, wherein the first yarn includes cotton yarn and spandex, and the second yarn includes nylon filament and spandex;

[0007] In the knitting structure of the weft-knitted fabric, one knitting cycle consists of loops from two knitting rows: a first knitting row and a second knitting row. The loops from the first and second knitting rows are knitted into the fabric by repeating the cycle.

[0008] The first knitting row is a weft plain needle loop formed by the first yarn, and the spandex is knitted together with the cotton yarn by adding yarn;

[0009] The second weaving row is a weft plain needle loop row formed by the second yarn, and the spandex is woven together with the nylon filament by adding yarn.

[0010] Alternatively, the fineness of the cotton yarn is greater than or equal to 80S, and the fineness of the nylon filament is less than or equal to 70D.

[0011] The spandex fineness in the first and second yarns is less than or equal to 30D.

[0012] Alternatively, the length of the nylon filament can be greater than that of the cotton yarn.

[0013] Alternatively, the cotton yarn can be a long-staple combed compact spun cotton yarn with a fineness of 80S and a thread length of 250mm / 100 stitches.

[0014] The nylon filament is fully dull nylon FDY with a fineness of 70D / 24F and a thread length of 275mm / 100 stitches.

[0015] Alternatively, the cotton yarn can be a combed compact spun cotton yarn with a fineness of 80S and a thread length of 255mm / 100 stitches.

[0016] The nylon filament is semi-dull nylon with a fineness of 72D / 36F and a thread length of 280mm / 100 stitches.

[0017] Alternatively, the combed compact cotton yarn may be made of 50% long-staple cotton fibers and 50% short-staple cotton fibers.

[0018] Alternatively, the cotton yarn can be a long-staple combed compact spun cotton yarn with a fineness of 100S and a thread length of 270mm / 100 stitches.

[0019] The nylon filament is fully dull nylon FDY with a fineness of 50D / 18F and a thread length of 290mm / 100 stitches.

[0020] Alternatively, the spandex in the first and second yarns can be 20-30D in fineness and 100-105mm / 100 stitches in length.

[0021] Alternatively, the weft-knitted fabric may have a longitudinal density of 46-48 loops per inch.

[0022] Alternatively, the weft-knitted fabric may have a weight per square meter of 110-130 g / m². 2 .

[0023] The beneficial effects of this utility model are as follows:

[0024] To address the technical problems existing in the prior art, this utility model provides a weft-knitted fabric that achieves complementary and optimized fabric performance through the rational configuration of three textile materials: cotton yarn, nylon filament, and spandex. The addition of nylon filament not only endows the fabric with excellent physical strength and deformation recovery, allowing it to maintain its lightweight characteristics while meeting the mechanical needs of daily wear, ensuring freedom of movement and effectively improving the fabric's shape retention; furthermore, the nylon's long-filament yarn structure significantly enhances the fabric's wrinkle resistance, abrasion resistance, and pilling resistance, extending its lifespan. The inclusion of cotton yarn fully utilizes its natural moisture-wicking properties and soft touch, compensating for the poor moisture absorption of nylon filament, enhancing the fabric's skin-friendly comfort and solving the problems of poor skin-friendliness and moisture absorption associated with synthetic fibers. The addition of spandex provides the fabric with suitable elasticity, accommodating the stretching needs of body activity and ensuring rapid rebound after repeated stretching, further enhancing its shape retention.

[0025] This invention employs a special weaving structure that alternates between cotton yarn and nylon filament (i.e., the first row of cotton yarn and the second row of nylon filament yarn alternately form a double-row repetitive unit), combined with a high longitudinal density (46-48 loops / inch), resulting in a regularly alternating grid-like loop structure in the fabric. This structural design creates evenly distributed gaps within the fabric, significantly improving breathability and allowing for the rapid expulsion of warm, moist air from the skin's surface. Simultaneously, the regular loop arrangement and alternating support structure enhance the overall stability of the fabric, making it less prone to deformation during washing and better maintaining its original shape. This solves the problems of traditional lightweight fabrics being prone to loosening and having poor shape retention.

[0026] In summary, this utility model, through the synergistic effect of material selection and structural design, enables the fabric to simultaneously possess excellent skin-friendliness, breathability, moisture absorption, and shape retention, while also taking into account its lightweight characteristics and durability, thus meeting the dual needs of modern clothing for comfort and practicality.

[0029] Figure 2 This diagram shows the loop weaving pattern of the fabric provided in an embodiment of the present invention. Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise expressly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not being in direct contact but through another feature between them.

[0033] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] To address the shortcomings of existing technologies, this utility model provides a weft-knitted fabric, which is a lightweight single-sided knitted fabric with excellent skin-friendliness, breathability, moisture absorption, and shape retention properties. Combined with... Figure 1-2 As shown, the weft-knitted fabric comprises a first yarn and a second yarn arranged alternately. The first yarn consists of cotton yarn 1 and spandex 3, and the second yarn consists of nylon filament and spandex 3.

[0035] In the knitting structure of a weft-knitted fabric, one knitting cycle consists of loops from two knitting rows, the first knitting row 100 and the second knitting row 200. The loops of the first knitting row 100 and the second knitting row 200 are knitted into the fabric by repeating the cycle.

[0036] The first knitting row 100 is a weft plain knitting loop row formed by the first yarn, which is a weft plain knitting structure formed by adding spandex 3 together with cotton yarn 1.

[0037] The second knitting row 200 is a weft plain knitting loop row formed by the second yarn, which is a weft plain knitting structure formed by adding yarn to spandex 3 together with nylon filament 2.

[0038] Nylon filament is a strong synthetic fiber, but compared to cotton yarn, its moisture absorption is poor, resulting in poor breathability when used in summer close-fitting fabrics. In this embodiment, by alternating cotton yarn and nylon filament, and adding spandex, the excellent skin-friendly and moisture-absorbing properties of cotton yarn are utilized, while the strength of nylon filament and the elasticity of spandex provide a foundation for the fabric's shape retention. Furthermore, the reasonable combination of these two natural and synthetic fibers avoids the limitations of single-fiber performance, achieving a preliminary balance between skin-friendliness, moisture absorption, and shape retention.

[0039] The plain weave itself has good breathability, and combined with the natural moisture-absorbing properties of cotton yarn, it can quickly absorb sweat from the skin. Spandex is added as a filler yarn, which does not affect the skin-friendly feel of the cotton yarn, while providing moderate elasticity to the fabric, preventing it from loosening after stretching and enhancing its shape retention. Nylon filament has good strength and abrasion resistance, and its synergistic effect with spandex improves the fabric's wrinkle resistance and shape retention. The filler yarn method allows the nylon filament and spandex to form a stable loop structure, maintaining the fabric's shape stability. At the same time, the loose nature of the plain weave retains good breathability, achieving a balanced overall breathability performance in conjunction with the first row.

[0040] In one specific embodiment, during the weaving process, the selected cotton yarn 1 should have a fineness greater than or equal to 80S, and the nylon filament 2 should have a fineness less than or equal to 70D. The spandex 3 in the first and second yarns should have a fineness less than or equal to 30D. A cotton yarn fineness ≥80S means the yarn is finer and softer, improving its skin-friendly feel; the characteristics of nylon filament 2 fineness ≤70D and spandex 3 fineness ≤30D ensure the overall fabric is lightweight, avoiding a heavy feel. Simultaneously, the finer denier fibers create more uniform loop gaps, promoting breathability, and the finer denier spandex has a softer elasticity, ensuring shape retention without compromising wearing comfort.

[0041] In one specific embodiment, the nylon filament 2 has a longer thread length than the cotton yarn 1. The longer thread length of the nylon filament 2 allows it to form a more complete support structure on the fabric surface, enhancing shape retention; the relatively shorter thread length of the cotton yarn 1 makes it more skin-friendly, highlighting its skin-friendly and moisture-wicking effects. The complementary structure formed by the difference in thread length ensures the stability of the fabric shape without affecting its skin-friendly and breathable properties.

[0042] In one specific embodiment, the cotton yarn 1 is specifically selected from long-staple cotton combed compact spun cotton yarn with a fineness of 80S and a thread length of 250mm / 100 stitches.

[0043] The nylon filament 2 is made of fully dull nylon FDY with a fineness of 70D / 24F and a thread length of 275mm / 100 stitches.

[0044] Specifically, spandex 3 is selected with a fineness of 30D and a thread length of 100mm / 100 needles.

[0045] In this embodiment, the long-staple cotton combed compact spun yarn has fine and long fibers with few impurities, and excellent skin-friendliness and moisture absorption properties; the fully dull nylon FDY has a soft luster and high strength, and combined with the moderate elasticity of 30D spandex, the fabric has good shape retention, while the fine denier characteristics of 80S cotton yarn and 70D nylon keep it light and breathable. The yarn length ratio further optimizes the stability and breathability of the loop structure.

[0046] In one specific embodiment, the cotton yarn 1 is specifically selected as combed compact spun cotton yarn with a fineness of 80S and a thread length of 255mm / 100 stitches.

[0047] The nylon filament 2 is made of semi-dull nylon with a fineness of 72D / 36F and a thread length of 280mm / 100 stitches.

[0048] Specifically, spandex 3 is selected with a fineness of 30D and a thread length of 100mm / 100 needles.

[0049] In this embodiment, the raw materials for the selected combed compact cotton yarn are 50% long-staple cotton fiber and 50% short-staple cotton fiber. Long-staple cotton fiber is longer, more uniform in fineness, and has a finer average fineness than short-staple cotton fiber, but it is more expensive. Therefore, to ensure the cotton yarn is cooled while simultaneously reducing production costs, this embodiment uses a blend of long-staple and short-staple cotton fibers, resulting in cotton yarn of better quality and lower production costs.

[0050] In this embodiment, the combed compact spun cotton yarn, a blend of 50% long-staple cotton fiber and 50% short-staple cotton fiber, retains the skin-friendly softness and moisture-wicking properties of long-staple cotton while reducing costs through short-staple cotton, resulting in stable yarn quality. The multi-fiber structure of semi-dull nylon 36F makes the fabric feel more delicate, and the elasticity of 30D spandex enhances the fabric's shape retention. The yarn length design ensures reasonable loop spacing, guaranteeing breathability and achieving a balance between skin-friendliness, breathability, shape retention, and cost.

[0051] In one specific embodiment, the cotton yarn 1 is specifically selected from long-staple cotton combed compact spun cotton yarn with a fineness of 100S and a thread length of 270mm / 100 stitches.

[0052] The nylon filament 2 is made of fully dull nylon FDY with a fineness of 50D / 18F and a thread length of 290mm / 100 stitches.

[0053] Specifically, spandex 3 is selected with a fineness of 20D and a thread length of 105mm / 100 needles.

[0054] In this embodiment, the 100S long-staple cotton combed compact spun yarn is finer and softer, with better skin-friendliness and moisture absorption; the 50D nylon filament and 20D spandex further reduce the fabric weight, enhancing its lightness and breathability; the low elasticity of 20D spandex makes the fabric more shape-retaining, suitable for close-fitting wear, and the increased yarn length makes the coil structure more stable, avoiding deformation.

[0055] In one specific embodiment, the spandex in the first and second yarns has a fineness of 20-30D and a thread length of 100-105mm / 100 stitches. The 20-30D spandex fineness provides moderate elasticity, ensuring that the fabric can return to its original shape after stretching (shape retention) without causing a tight feeling when worn due to excessive elasticity; the 100-105mm / 100 stitches thread length ensures that the spandex is evenly distributed in the yarn, working synergistically with cotton yarn and nylon filament to prevent excessive shrinkage of the spandex from affecting the fabric's breathability and skin-friendly feel, thus achieving a balance between elasticity and comfort.

[0056] In one specific embodiment, the longitudinal density of the weft-knitted fabric is 46-48 loops / inch. A longitudinal density of 46-48 loops / inch falls within the medium-high density range, ensuring stable loop structure, improving the fabric's resistance to deformation and shape retention, while avoiding excessively high density that would result in too small loop gaps and affect breathability. Simultaneously, the moderate density gives the fabric a delicate hand feel, enhancing its skin-friendly experience.

[0057] In one specific embodiment, the square weight of the weft-knitted fabric is 110-130 g / m². 2 It should be noted that the weight per square meter of the fabric mentioned in this embodiment refers to the weight per square meter of the greige fabric. The weight per square meter after dyeing will be determined according to specific circumstances. The weft-knitted fabric provided in this embodiment is relatively lightweight, which can reduce the stuffiness when wearing it and improve breathability. At the same time, the lightweight structure combined with a reasonable yarn combination can maintain good shape retention while ensuring the fabric's skin-friendly and moisture-wicking properties, making it suitable for making summer or close-fitting clothing.

[0058] The advantages of the weft-knitted fabric provided by the present invention will be explained below through specific embodiments.

[0059] Example 1

[0060] The weft-knitted fabric is woven using a 34-inch 28G weft circular knitting machine. The smallest cycle unit consists of two knitting rows: the first knitting row and the second knitting row. The first knitting row is a row of plain weft stitches woven from the first yarn, and the second knitting row is a row of plain weft stitches woven from the second yarn. The first yarn includes cotton yarn and spandex, with spandex acting as a filler yarn woven together with the cotton yarn. The second yarn includes nylon filament and spandex, with spandex acting as a filler yarn woven together with the nylon filament.

[0061] The cotton yarn used is 80S long-staple combed compact cotton yarn, the nylon filament is 70D / 24F fully dull nylon FDY, and the spandex is 30D spandex. In this embodiment, the weft-knitted fabric has a longitudinal density of 46 loops / inch, the long-staple combed compact cotton yarn has a yarn length of 250mm / 100 stitches, the fully dull nylon FDY has a yarn length of 275mm / 100 stitches, and the spandex has a yarn length of 100mm / 100 stitches. The weft-knitted fabric woven with these yarn length specifications has a fine texture and good smoothness, and the fabric's base weight is 130g / m². 2 The square weight after staining is 150 g / m². 2 .

[0062] In this embodiment, 80S long-staple combed compact cotton yarn ensures the fabric's skin-friendliness and moisture absorption, while the combination of 70D nylon filament and 30D spandex enhances the fabric's shape retention and wrinkle resistance; the longitudinal density is 46 loops / inch and the yarn density is 130g / m². 2 The weight makes the fabric both lightweight and breathable, while the fine texture and smoothness enhance wearing comfort, and it can maintain good overall performance after dyeing.

[0063] Example 2

[0064] The weft-knitted fabric is woven using a 34-inch 28G weft circular knitting machine. The smallest cycle unit consists of two knitting rows: the first knitting row and the second knitting row. The first knitting row is a row of plain weft stitches woven from the first yarn, and the second knitting row is a row of plain weft stitches woven from the second yarn. The first yarn includes cotton yarn and spandex, with spandex acting as a filler yarn woven together with the cotton yarn. The second yarn includes nylon filament and spandex, with spandex acting as a filler yarn woven together with the nylon filament.

[0065] The cotton yarn is made of 80S combed compact spun cotton yarn, which is a blend of 50% long-staple cotton fiber and 50% short-staple cotton fiber. Long-staple cotton fiber is longer, finer, and has a finer average fineness than short-staple cotton fiber, but it is more expensive. Therefore, in order to ensure the quality of the cotton yarn and reduce production costs, this embodiment uses a blend of long-staple cotton fiber and short-staple cotton fiber to obtain combed compact spun cotton yarn. This cotton yarn has good quality and can reduce production costs.

[0066] The nylon filament used is 72D / 36F semi-dull nylon, and the spandex is 30D spandex. In this embodiment, the weft-knitted fabric has a longitudinal density of 48 loops / inch, a combed compact spun cotton yarn length of 255mm / 100 stitches, a semi-dull nylon yarn length of 280mm / 100 stitches, and a spandex yarn length of 100mm / 100 stitches. The weft-knitted fabric woven with these yarn lengths is lightweight, breathable, retains its shape well, and has high strength. The fabric's weight per square meter after dyeing is 150g / m².2 .

[0067] In this embodiment, blended cotton yarn is used to reduce costs while ensuring skin-friendly and moisture-wicking properties. 72D semi-dull nylon improves the softness and strength of the fabric, and 30D spandex ensures the fabric's shape retention. Reasonable longitudinal density makes the fabric structure more stable. Combined with its lightweight characteristics and good breathability, it is suitable for long-term close-fitting wear. Its high strength also extends the fabric's service life.

[0068] Example 3

[0069] The weft-knitted fabric is woven using a 34-inch 28G weft circular knitting machine. The smallest cycle unit consists of two knitting rows: the first knitting row and the second knitting row. The first knitting row is a row of plain weft stitches woven from the first yarn, and the second knitting row is a row of plain weft stitches woven from the second yarn. The first yarn includes cotton yarn and spandex, with spandex acting as a filler yarn woven together with the cotton yarn. The second yarn includes nylon filament and spandex, with spandex acting as a filler yarn woven together with the nylon filament.

[0070] The cotton yarn used is 100S long-staple combed compact cotton yarn, the nylon filament is 50D / 18F fully dull nylon FDY, and the spandex is 20D spandex. In this embodiment, the weft-knitted fabric has a longitudinal density of 55 loops / inch, a yarn length of 270mm / 100 stitches for the long-staple combed compact cotton yarn, a yarn length of 290mm / 100 stitches for the fully dull nylon FDY, and a yarn length of 105mm / 100 stitches for the spandex. The weft-knitted fabric woven with these yarn lengths has a fine texture and good smoothness, and the fabric's base weight is 110g / m². 2 The square weight after staining is 125 g / m². 2 .

[0071] In this embodiment, 100S long-staple cotton yarn can further enhance the fabric's skin-friendly and delicate feel and moisture absorption speed, while 50D nylon and 20D spandex make the fabric lighter and softer. The fabric's longitudinal density is in the high-density range, which can ensure the fabric's flatness and resistance to deformation. The low weight can also significantly enhance the fabric's breathability, making it particularly suitable for summer wear. The fine texture also enhances the fabric's appearance and texture.
