Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a moisture-wicking warp-knitted fabric and its garments. Background Technology

[0002] With the growing popularity of urban sportswear, a new style of clothing is gradually being accepted by the public. This style is suitable for both office wear and the needs of slow-paced urban activities. Urban sportswear not only needs to meet the requirements of formal occasions, but also needs to be adaptable to more casual outdoor sports and fitness activities.

[0003] Woven fabrics, due to their unique interlacing structure, possess a firm yet elastic nature, allowing them to maintain their shape while exhibiting excellent dimensional stability. However, this tight weave also limits their moisture-wicking properties. In hot summers or during strenuous exercise, the fabric's breathability and moisture-wicking ability can make people feel stuffy and uncomfortable.

[0004] Weft-knitted fabrics, with their softness, breathability, good stretch, and excellent moisture-wicking properties, are widely used in sportswear and casual wear. However, the loop structure of weft-knitted fabrics is relatively loose, and fibers are prone to shifting, leading to fabric deformation. This deformation becomes more pronounced after repeated washing and wearing, affecting the fabric's shape retention. Therefore, finding fabrics that simultaneously possess shape retention, moisture-wicking properties, and comfort has become crucial. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a moisture-wicking warp-knitted fabric and its garments that are crisp, stylish, and have good moisture-wicking properties.

[0006] To achieve the above objectives, the various embodiments of the present invention employ the following technical solutions, but are not limited to the following solutions:

[0007] The first technical solution relates to a moisture-wicking warp-knitted fabric and its garment, comprising a fabric body, wherein the fabric body is woven by warp knitting using guide bars GB1 and GB2, wherein the backing yarn of guide bar GB1 is a moisture-wicking yarn, and the backing yarn of guide bar GB2 is an elastic yarn; the ratio X of the width X formed by the open loops of the fabric body to the width Y formed by the horizontal distance between the three adjacent closed loops on one side, the open loops and the closed loops is X / Y = 1 / 4 to 1 / 3, and the angle α formed by the in-exit extension line and the out-exit extension line of the first yarn forming the loop in the fabric body is 90° to 160°.

[0008] The second technical solution is based on the first technical solution, wherein the moisture-absorbing yarn is the outer layer and inner layer of the fabric, and the elastic yarn is the middle layer of the fabric.

[0009] The third technical solution is based on the second technical solution, wherein the moisture-absorbing yarn is a highly moisture-absorbing and releasing nylon containing polyvinylpyrrolidone, with a fineness of 20T to 84T, and the moisture-absorbing yarn accounts for more than 70% of the moisture-absorbing warp-knitted fabric.

[0010] The fourth technical solution is based on the second technical solution, wherein the elastic yarn is spandex with a fineness of 20D to 60D, and the elastic yarn accounts for less than 30% of the moisture-absorbing warp-knitted fabric.

[0011] The fifth technical solution is based on the first to fourth technical solutions, wherein a garment is made of a moisture-absorbing warp-knitted fabric as described above.

[0012] As can be seen from the above description of the various embodiments of the present invention, compared with the prior art, the various embodiments of the present invention have the following advantages:

[0013] Beneficial effects:

[0014] In the first technical solution and related embodiments, since the padding yarn of the comb GB1 is a moisture-absorbing yarn, this yarn can absorb sweat and quickly dissipate it, keeping the skin dry. The padding yarn of the comb GB2 is an elastic yarn, which can provide good elasticity, giving the fabric a certain degree of stretchability to adapt to body movement and shape changes.

[0015] This moisture-wicking warp-knitted fabric uses moisture-wicking yarns to weave a wide striped structure, which improves the fabric's moisture absorption and wicking properties; the structure formed by X and Y can expel absorbed moisture through capillary effect.

[0016] The angle α formed by the infeed and outfeed extension lines of the coil can suppress excessive stretching, giving the fabric a certain degree of shape retention. If the angle α is less than 90°, the extension lines are too densely distributed in the longitudinal direction, making longitudinal stretching difficult and resulting in poor movement when worn. If the angle α is greater than 160°, the extension lines are too densely distributed in the transverse direction, making transverse stretching difficult and resulting in poor movement when worn.

[0017] The combination of moisture-wicking and elastic yarns enhances the fabric's durability. The quick-drying and durable properties of the moisture-wicking yarns reduce sweat buildup, minimizing wear and fading. Meanwhile, the durability of the elastic yarns maintains the fabric's structural stability and appearance. This type of fabric offers advantages such as moisture absorption and breathability, elastic comfort, structural stability, good stretch, and wide applicability, meeting the needs of various occasions and applications.

[0018] In the second technical solution and related embodiments, the elastic yarn, as the middle layer, provides good elasticity, giving the fabric a certain degree of stretch and adapting to body movement and shape changes. Simultaneously, the moisture-wicking yarn, as the outer and inner layers, can better absorb and dissipate sweat, keeping the body dry. This robust structural design enhances the fabric's durability and comfort.

[0019] In the third technical solution and related embodiments, the highly absorbent nylon contains polyvinylpyrrolidone, which has excellent moisture absorption and quick-drying properties. In humid or hot environments, this material can quickly absorb sweat and evaporate it rapidly, keeping the skin dry and providing the wearer with extreme comfort. Highly absorbent nylon also has good breathability and elasticity, allowing air circulation and reducing stuffiness. Simultaneously, this material has excellent adaptability, accommodating different body shapes and activity needs. This design utilizes the advantages of highly absorbent nylon containing polyvinylpyrrolidone as a moisture-wicking yarn, enabling it to play a crucial role in moisture-wicking warp-knitted fabrics, thereby providing wearers with better comfort and adaptability, and making it suitable for various applications requiring good breathability and adaptability.

[0020] In the fourth technical solution and related embodiments, spandex, as an elastic yarn, provides excellent elasticity, allowing the fabric to better adapt to body movements and shape changes. This elasticity increases wearing comfort and freedom of movement, reducing feelings of restriction. Spandex has a fineness of 20D to 60D; yarns within this range are relatively coarse, thus possessing good durability. This means that this elastic yarn can withstand multiple washes and abrasions while maintaining its original performance and appearance. This design utilizes the advantages of spandex as an elastic yarn, enabling it to play a crucial role in moisture-wicking warp-knitted fabrics, thereby providing wearers with greater comfort and freedom of movement, and is suitable for various applications requiring adaptation to body movements and shape changes.

[0021] In the fifth technical solution and related embodiments, the moisture-wicking warp-knitted fabric has good shape retention and good moisture absorption and perspiration wicking effect. Clothing made of such fabric is not only suitable for sports occasions, but also for business occasions, which greatly improves the convenience of wearing. Attached Figure Description

[0030] See Figures 1 to 2 , Figures 1 to 2 A schematic diagram of the moisture-wicking warp-knitted fabric in the embodiment is shown; as follows: Figures 1 to 2 As shown, the moisture-wicking warp-knitted fabric includes a fabric body, which is woven from combs GB1 and GB2 using a warp-knitting method.

[0031] The padding yarn of the comb GB1 is a moisture-absorbing yarn; the moisture-absorbing yarn is used for the outer and inner layers of the fabric. The moisture-absorbing yarn is a highly moisture-absorbing and releasing nylon containing polyvinylpyrrolidone, with a fineness of 20T to 84T. The moisture-absorbing yarn accounts for more than 70% of the moisture-absorbing warp-knitted fabric.

[0032] The padding yarn of the GB2 comb is an elastic yarn; the elastic yarn is the middle layer of the fabric, the elastic yarn is spandex, the fineness is 20D to 60D, and the elastic yarn accounts for less than 30% of the moisture-absorbing warp-knitted fabric.

[0033] Preferably, the fineness of the highly absorbent nylon is 20T to 44T, and the fineness of the elastic yarn is 20D to 40D. In the fabric, the absorbent yarn accounts for 70% to 90% of the absorbent warp-knitted fabric, and the elastic yarn accounts for 10% to 30% of the absorbent warp-knitted fabric.

[0034] In this embodiment, the padding yarn of the comb GB1 is a moisture-absorbing yarn, which can absorb sweat and quickly dissipate it, keeping the skin dry. The padding yarn of the comb GB2 is an elastic yarn, which can provide good elasticity, giving the fabric a certain degree of stretch and adapting to body movements and shape changes.

[0035] In this embodiment, the highly absorbent nylon contains polyvinylpyrrolidone, which possesses excellent moisture absorption and quick-drying properties. In humid or hot environments, this material rapidly absorbs and evaporates sweat, keeping the skin dry and providing extreme comfort to the wearer. Highly absorbent nylon also offers excellent breathability and elasticity, allowing air circulation and reducing stuffiness. Furthermore, this material is highly adaptable, accommodating different body shapes and activity levels. This design leverages the advantages of highly absorbent nylon containing polyvinylpyrrolidone as a moisture-wicking yarn, enabling it to play a crucial role in moisture-wicking warp-knitted fabrics, thereby providing better comfort and adaptability for the wearer and making it suitable for various applications requiring good breathability and adaptability.

[0036] In this embodiment, spandex, as an elastic yarn, provides excellent elasticity, allowing the fabric to better adapt to body movements and shape changes. This elasticity increases comfort and freedom of movement, reducing feelings of restriction. Spandex has a fineness of 20D to 60D, a relatively coarse range, thus offering good durability. This means that this elastic yarn can withstand multiple washes and abrasions while maintaining its original performance and appearance. This design leverages the advantages of spandex as an elastic yarn, enabling it to play a crucial role in moisture-wicking warp-knitted fabrics, thereby providing wearers with greater comfort and freedom of movement, and making it suitable for various applications requiring adaptation to body movements and shape changes.

[0037] Figure 1This diagram illustrates the width X of the open loop and the width Y of the three adjacent loops in the moisture-wicking warp-knitted fabric of this embodiment. Point A is the upper vertex of the open loop extension line, point B is the lower vertex of the open loop extension line, and point C is the lower vertex of the closed loop extension line. Dashed lines d, e, and f are horizontal lines extending left and right from point A, point B, and point C, respectively. X is the vertical distance between dashed lines d and e; Y is the vertical distance between dashed lines e and f.

[0038] Figure 2 This diagram illustrates the angle α formed by the in-line and out-line extension lines of the moisture-wicking warp-knitted fabric in this embodiment. Where a is the vertex of the open-loop extension line; b is the vertex of the closed-loop extension line; c is the intersection of the open-loop and closed-loop extension lines; and α is the angle formed by ac and bc.

[0039] The ratio X / Y, where the width X formed by the open loops of the fabric body is equal to the width Y formed by the horizontal distance between the three adjacent closed loops, open loops, and closed loops on one side, is 1 / 4 to 1 / 3. This moisture-wicking warp-knitted fabric forms a striped structure of this width through the weaving of moisture-wicking yarns, improving the fabric's moisture absorption and wicking properties. The structure formed by X and Y can expel absorbed moisture through capillary effect. More preferably, X / Y = 1 / 4 to 3 / 10.

[0040] The angle α formed by the infeed and outfeed extension lines of the first yarn forming the loop in the fabric body is 90° to 160°. This angle α can suppress excessive stretching, giving the fabric a certain degree of shape retention. If the forming angle α is less than 90°, the extension lines are too densely distributed in the longitudinal direction, making longitudinal stretching difficult and resulting in poor movement when worn. If the forming angle α is greater than 160°, the extension lines are too densely distributed in the transverse direction, making transverse stretching difficult and resulting in poor movement when worn. Preferably, the angle α formed by the infeed and outfeed extension lines of the first yarn forming the loop is 100° to 130°.

[0041] As a preferred option, the total moisture resistance Ret of the moisture-wicking warp-knitted fabric is <75.

[0042] Preferably, the contact cooling Q-max value of the moisture-wicking warp-knitted fabric is Q-max≥0.20.

[0043] In this embodiment, the elastic yarn, as the middle layer, provides good elasticity, giving the fabric a certain degree of stretch to adapt to body movement and shape changes. Meanwhile, the moisture-wicking yarn, as the outer and inner layers, can better absorb and wick away sweat, keeping the body dry. This robust structural design enhances the fabric's durability and comfort.

[0044] In this embodiment, the combination of moisture-wicking yarn and elastic yarn enhances the fabric's durability. The quick-drying and durable properties of the moisture-wicking yarn reduce sweat buildup on the fabric, minimizing wear and fading. Meanwhile, the durability of the elastic yarn helps maintain the fabric's structural stability and appearance. This fabric offers advantages such as moisture absorption and breathability, elastic comfort, structural stability, good stretchability, and wide applicability, meeting the needs of various occasions and applications.

[0045] A garment is made from the aforementioned moisture-wicking warp-knitted fabric. This moisture-wicking warp-knitted fabric has good shape retention and excellent moisture absorption and wicking properties. Garments made from this fabric are suitable not only for sports occasions but also for business occasions, greatly improving the convenience of wearing them.
