Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a hygroscopic warp knitted fabric and clothing thereof. Background Art

[0002] As urban sports become more and more popular, a new style of clothing is gradually being accepted by the public. This style is suitable for office wear and can also meet the needs of urban slow sports. Urban slow sports clothing should not only meet the needs of formal occasions, but also adapt to more casual outdoor sports and fitness activities.

[0003] Woven fabrics have a unique structure of warp and weft, which creates a strong and elastic property, allowing them to maintain their shape while having excellent dimensional stability. However, this tight weaving method also limits their moisture wicking performance. In hot summer days or during intense exercise, the breathability and moisture wicking properties of this fabric may make people feel stuffy and uncomfortable.

[0004] Weft knitted fabrics are widely used in sportswear and casual wear for their softness, breathability, good stretchability, and excellent moisture absorption and perspiration wicking properties. However, the coil structure of weft knitted fabrics is relatively loose, and the fibers are easily displaced, causing the fabric to deform. This deformation phenomenon is especially obvious after multiple washing and wearing, which affects the shape retention of the fabric. Therefore, it is critical to find fabrics that have shape retention, moisture absorption and perspiration wicking functions, and comfort. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned defects or problems existing in the background technology and to provide a hygroscopic warp knitted fabric and clothing thereof, which is stiff and stylish and has good moisture absorption and perspiration elimination effect.

[0006] To achieve the above objectives, each embodiment of the present invention adopts the following technical solutions but is not limited to the following solutions:

[0007] The first technical scheme relates to a hygroscopic warp knitted fabric and clothing thereof, comprising a fabric body, wherein the fabric body is woven by a combing bar GB1 and a combing bar GB2 in a warp knitting manner, the inlay yarn of the combing bar GB1 is a hygroscopic yarn, and the inlay yarn of the combing bar GB2 is an elastic yarn; the ratio of the width X formed by the open coils of the fabric body to the width Y formed by three adjacent closed coils on one side and the horizontal distance between the open coils and the closed coils is X / Y=1 / 4~1 / 3, and the angle α formed by the in-extension line and the out-extension line of the coil formed by the first yarn in the fabric body is 90°~160°.

[0008] The second technical solution is based on the first technical solution, wherein the hygroscopic yarn is the surface layer and the 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 hygroscopic yarn is nylon with high moisture absorption and release properties and a fineness of 20T to 84T, and the hygroscopic yarn accounts for more than 70% of the hygroscopic 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 hygroscopic warp knitted fabric.

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

[0012] From the above description of the various embodiments of the present invention, it can be seen that, compared with the prior art, the various embodiments of the present invention have the following beneficial effects:

[0013] In the first technical solution and related embodiments, since the inlay yarn of the combing bar GB1 is a hygroscopic yarn, this yarn can absorb sweat and quickly dissipate it to keep the skin dry. The inlay yarn of the combing bar GB2 is an elastic yarn, which can provide good elasticity, so that the fabric has a certain degree of stretchability and adapts to the movement and shape changes of the body.

[0014] The hygroscopic warp knitted fabric is woven by hygroscopic yarns to form a wide stripe structure, thereby improving the moisture absorption and moisture conduction performance of the fabric; the structure formed by X and Y can discharge the absorbed moisture through the capillary effect.

[0015] The angle α formed by the inward and outward extension lines of the coil can suppress excessive stretching and make the fabric have a certain shape retention. If the angle α is less than 90°, the extension lines are too densely distributed in the longitudinal direction, making it difficult to stretch in the longitudinal direction and the mobility is poor when worn. If the angle α is greater than 160°, the extension lines are too densely distributed in the transverse direction, making it difficult to stretch in the transverse direction and the mobility is poor when worn.

[0016] Due to the combination of hygroscopic yarn and elastic yarn, the durability of the fabric can be enhanced. The quick-drying and durability of the hygroscopic yarn can reduce the accumulation of sweat on the fabric, reduce the wear and fading of the fabric. The durability of the elastic yarn can also maintain the structural stability and appearance of the fabric. This fabric has the advantages of moisture absorption and breathability, elasticity and comfort, stable structure, good ductility and a wide range of applications, which can meet the application of different occasions and different needs.

[0017] In the second technical solution and related embodiments, the elastic yarn as the middle layer can provide good elasticity, so that the fabric has a certain degree of stretchability and adapts to the movement and shape changes of the body. At the same time, the hygroscopic yarn as the surface layer and the inner layer can better absorb and dissipate sweat to keep the body dry. This structurally stable design can enhance the durability and comfort of the fabric.

[0018] In the third technical solution and related embodiments, since the high hygroscopic and dehygroscopic nylon contains polyvinyl pyrrolidone, it has excellent hygroscopicity and quick-drying properties. In a humid or hot environment, this material can quickly absorb sweat and evaporate it quickly, keeping the skin dry and giving the wearer extreme comfort. High hygroscopic and dehygroscopic nylon has good air permeability and elasticity, which can allow air circulation and reduce the body's stuffiness. At the same time, this material has good adaptability and can adapt to different body shapes and sports needs. This design utilizes the advantages of high hygroscopic and dehygroscopic nylon containing polyvinyl pyrrolidone as hygroscopic yarn, allowing it to play an important role in hygroscopic warp knitted fabrics, thereby providing better comfort and adaptability for the wearer, and is suitable for various applications requiring good air permeability and adaptability.

[0019] In the fourth technical solution and related embodiments, spandex is used as an elastic yarn to provide good elasticity, so that the fabric can better adapt to the movement and shape changes of the body. This elasticity can increase the comfort and freedom of wearing and reduce the sense of restraint. The fineness of spandex is 20D to 60D, and the yarn in this range is relatively thick, so it has good durability. This means that this elastic yarn can withstand multiple washings and wears and maintain its original performance and appearance. This design takes advantage of the advantages of spandex as an elastic yarn, allowing it to play an important role in hygroscopic warp knitted fabrics, thereby providing the wearer with better comfort and freedom, and is suitable for various applications that need to adapt to body movement and shape changes.

[0020] In the fifth technical solution and related embodiments, the hygroscopic warp knitted fabric has good shape retention and good moisture absorption and perspiration removal effects. Clothes made of such fabrics are not only suitable for sports occasions, but also for business occasions, greatly improving the convenience of wearing. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Preferably, the fineness of the high moisture absorption and release nylon is 20T-44T, and the fineness of the elastic yarn is 20D-40D. In the fabric, the hygroscopic yarn accounts for 70%-90% of the hygroscopic warp knitted fabric, and the elastic yarn accounts for 10%-30% of the hygroscopic warp knitted fabric.

[0033] In this embodiment, since the inlay yarn of the combing bar GB1 is a hygroscopic yarn, this yarn can absorb sweat and quickly dissipate it to keep the skin dry. The inlay yarn of the combing bar GB2 is an elastic yarn, which can provide good elasticity, so that the fabric has a certain elasticity and adapts to the movement and shape change of the body.

[0034] In this embodiment, since the high hygroscopic and desorption nylon contains polyvinyl pyrrolidone, it has excellent hygroscopicity and quick-drying properties. In a humid or hot environment, this material can quickly absorb sweat and evaporate it quickly, keeping the skin dry and giving the wearer an extremely comfortable feeling. High hygroscopic and desorption nylon has good air permeability and elasticity, which can allow air circulation and reduce the body's stuffiness. At the same time, this material has good adaptability and can adapt to different body shapes and sports needs. This design utilizes the advantages of high hygroscopic and desorption nylon containing polyvinyl pyrrolidone as hygroscopic yarn, so that it plays an important role in hygroscopic warp knitted fabrics, thereby providing better comfort and adaptability for the wearer, and is suitable for various applications requiring good air permeability and adaptability.

Point A is the upper vertex of the open coil extension line, point B is the lower vertex of the open coil extension line, point C is the lower vertex of the closed coil extension line, dotted line d is the horizontal line extending from point A to the left and right, dotted line e is the horizontal line extending from point B to the left and right, and dotted line f is the horizontal line extending from point C to the left and right.

Wherein a is the vertex of the open coil extension line; b is the vertex of the closed coil extension line; c is the intersection of the open coil extension line and the closed coil extension line; α is the angle formed by ac and bc.

[0038] The ratio of the width X formed by the open coil of the fabric body to the width Y formed by the horizontal distance between the three adjacent closed coils on one side and the open coil and the closed coil is X / Y = 1 / 4 to 1 / 3. The hygroscopic warp knitted fabric is woven by hygroscopic yarn to form a stripe structure of width, which improves the moisture absorption and moisture conduction performance of the fabric; the structure formed by X and Y can discharge the absorbed moisture through the capillary effect. More preferably, X / Y = 1 / 4 to 3 / 10.

[0039] The angle α formed by the inlet extension line and the outlet extension line of the coil formed by the first yarn in the fabric body is 90° to 160°. The angle α formed by the inlet extension line and the outlet extension line of the coil can suppress excessive stretching and make the fabric have a certain shape retention. If the angle α is less than 90°, the extension lines are too densely distributed in the longitudinal direction, so that the longitudinal stretching performance is difficult and the mobility is poor when worn. If the angle α is greater than 160°, the extension lines are too densely distributed in the transverse direction, so that the transverse stretching performance is difficult and the mobility is poor when worn. Preferably, the angle α formed by the inlet extension line and the outlet extension line of the coil formed by the first yarn is 100° to 130°.

[0040] Preferably, the total moisture resistance value of the hygroscopic warp knitted fabric Ret is less than 75.

[0041] Preferably, the contact coolness Q-max value of the hygroscopic warp knitted fabric is Q-max≥0.20.

[0042] In this embodiment, the elastic yarn as the middle layer can provide good elasticity, so that the fabric has a certain degree of stretchability and adapts to the body's movement and shape changes. At the same time, the hygroscopic yarn as the surface layer and the inner layer can better absorb and dissipate sweat to keep the body dry. This structurally stable design can enhance the durability and comfort of the fabric.

[0043] In this embodiment, the combination of the hygroscopic yarn and the elastic yarn can enhance the durability of the fabric. The quick-drying and durability of the hygroscopic yarn can reduce the accumulation of sweat on the fabric, reduce the wear and fading of the fabric. The durability of the elastic yarn can also maintain the structural stability and appearance of the fabric. This fabric has the advantages of moisture absorption and breathability, elasticity and comfort, stable structure, good ductility and a wide range of applications, and can meet the application of different occasions and different needs.
