Description

Hygroscopic warp knitted fabric and garment thereof

Technical Field

The invention relates to the technical field of textile, in particular to a hygroscopic warp knitted fabric and clothing thereof.

Background

With the increasing popularity of urban sports, a novel clothing style is gradually accepted by the masses, and the style is suitable for office wear and can meet the requirement of urban slow sports. The city slow-movement garment not only meets the wearing requirement of formal occasions, but also can adapt to more random outdoor exercises and body-building activities.

The woven fabric has the characteristics of rigidity and elasticity due to the unique structure of warp and weft interweaving, so that the woven fabric has excellent dimensional stability while keeping the shape. However, this tight weave also limits its moisture absorption and perspiration properties. The breathability and moisture absorption and perspiration properties of such fabrics may be uncomfortable and stuffy during hot summer or during strenuous exercise.

Weft knitting fabrics are widely applied in the fields of sportswear, sportswear and the like due to the characteristics of softness, ventilation, good extensibility, excellent moisture absorption and sweat release performances and the like. However, the loop structure of weft knitted fabrics is relatively loose and the fibers are easily displaced, resulting in fabric deformation. Especially after washing and wearing for many times, the deformation phenomenon is more obvious, so that the shape retention of the fabric is influenced. Therefore, it is critical to find a fabric with both shape retention, moisture absorption and perspiration functions and comfort.

Disclosure of Invention

The invention aims to overcome the defects or problems in the background art and provide the hygroscopic warp knitted fabric and the garment thereof, which are broad and have good hygroscopic and sweat-releasing effects.

In order to achieve the above objective, the following technical solutions are adopted in the embodiments of the present invention, but not limited to the following solutions:

the first technical scheme relates to a hygroscopic warp knitted fabric and clothing thereof, comprising a fabric body, wherein the fabric body is formed by knitting a guide bar GB1 and a guide bar GB2 in a warp knitting mode, the yarn-laying of the guide bar GB1 is hygroscopic yarn, and the yarn-laying of the guide bar GB2 is elastic yarn; the ratio X/Y=1/4-1/3 of the width X formed by the open coil of the fabric body to the width Y formed by the distances between the three adjacent closed coils, the open coil and the closed coil in the horizontal direction on one side, and the angle alpha formed by the inlet extension line and the outlet extension line of the first yarn forming coil in the fabric body is 90-160 degrees.

The second technical scheme is based on the first technical scheme, wherein the hygroscopic yarns are a surface layer and an inner layer of the fabric, and the elastic yarns are an intermediate layer of the fabric.

The third technical scheme is based on the second technical scheme, wherein the hygroscopic yarn is high-hygroscopicity nylon containing polyvinylpyrrolidone, the fineness is 20T-84T, and the hygroscopic yarn accounts for more than 70% of the hygroscopic warp knitted fabric.

The fourth technical scheme is based on the second technical scheme, wherein the elastic yarns are spandex, the fineness is 20D-60D, and the elastic yarns account for less than 30% of the hygroscopic warp knitted fabric.

A fifth technical solution is based on the first to fourth technical solutions, wherein a garment is made of the hygroscopic warp knitting fabric.

From the above description of various embodiments of the invention, it is apparent that, relative to the prior art, various embodiments of the invention have the following

The beneficial effects are that:

in the first technical solution and the related embodiments, since the yarn of the guide bar GB1 is a hygroscopic yarn, this yarn can absorb sweat and rapidly emit away, keeping the skin dry. The yarn is elastic yarn, so that the yarn can provide good elasticity, the fabric has certain elasticity, and the fabric adapts to the movement and the morphological change of the body.

The hygroscopic warp knitted fabric is woven through the hygroscopic yarns to form a stripe structure with the width, so that the hygroscopic property and the moisture permeability of the fabric are improved; the structure formed by X and Y is capable of expelling absorbed moisture by capillary effect.

The angle alpha formed by the inlet extension line and the outlet extension line of the coil can inhibit excessive stretching, so that the fabric has certain shape retention. If the angle alpha is smaller than 90 degrees, 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 the diaper is worn. If the angle alpha is larger than 160 degrees, 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 the belt is worn.

Due to the combination of the hygroscopic yarns and the elastic yarns, the durability of the fabric can be enhanced. The quick-drying property and durability of the hygroscopic yarn can reduce accumulation of sweat on the fabric and reduce abrasion and fading of the fabric. The durability of the elastic yarns can also maintain the structural stability and appearance of the fabric. The fabric has the advantages of moisture absorption, ventilation, elasticity, comfort, stable structure, good ductility, wide application range and the like, and can meet the application of different occasions and different requirements.

In the second technical scheme and related embodiments, the elastic yarn is used as the middle layer, so that good elasticity can be provided, the fabric has certain elasticity, and the fabric adapts to movement and morphological changes of a body. Meanwhile, the hygroscopic yarns are used as the surface layer and the inner layer, so that sweat can be absorbed and emitted better, and the dryness of the body can be kept. The design with stable structure can enhance the durability and comfort of the fabric.

In the third technical scheme and related embodiments, since the nylon with high hygroscopicity and moisture release contains polyvinylpyrrolidone, the nylon has excellent hygroscopicity and quick drying property. In a moist or hot environment, the material can quickly absorb sweat and quickly evaporate, keep skin dry and feel extremely comfortable to a wearer. The nylon with high hygroscopicity and high hygroscopicity has good air permeability and elasticity, can enable air to circulate, and reduces the stuffiness of a body. Meanwhile, the material has good adaptability and can adapt to different body forms and exercise requirements. The design utilizes the advantage of the high-hygroscopicity nylon containing polyvinylpyrrolidone as the hygroscopic yarn, so that the high-hygroscopicity nylon plays an important role in the hygroscopic warp-knitted fabric, thereby providing better comfort and adaptability for a wearer and being suitable for various occasions requiring good air permeability and adaptability.

In the fourth technical solution and related embodiments, spandex is used as an elastic yarn, so that good elasticity can be provided, and the fabric can better adapt to movement and morphological changes of a body. Such elasticity can increase comfort and freedom of wearing and reduce the sense of constraint. The titer of the spandex is 20D-60D, and the yarns in the range are relatively thick, so that the spandex has better durability. This means that such elastic yarns are able to withstand multiple washings and abrasions, maintaining their original properties and appearance. The design utilizes the advantages of spandex as elastic yarn, so that the spandex plays an important role in the hygroscopic warp knitted fabric, thereby providing better comfort and freedom for the wearer and being suitable for various application fields needing to adapt to body movement and morphological changes.

In the fifth technical scheme and related embodiments, the hygroscopic warp knitted fabric has the effects of good shape retention and good moisture absorption and perspiration, and the clothing made of the fabric is not only suitable for being worn in sports occasions, but also suitable for being worn in business occasions, so that the wearing convenience is greatly improved.
