Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to a moisture absorbing and perspiration wicking fabric. Background Art

[0002] Fabric is a material that can be used to make clothing. As people's living standards continue to improve, their requirements for clothing are also increasing, especially for various sportswear in summer. Since people sweat a lot when exercising, if the fabric cannot absorb and remove sweat in time, it will cause the fabric to adhere to the skin surface, causing a stuffy feeling and affecting the comfort of use. Therefore, the moisture absorption and perspiration performance of the fabric is crucial.

[0003] In the prior art, materials with good water absorption are often used to prepare fabrics to improve the sweat absorption capacity of the fabrics. Some technical solutions also use multi-layer composite structures, in which there is a hygroscopic layer formed by materials with good water absorption. Although the above methods can achieve a hygroscopic effect, the moisture is stored in the hydrophilic material and is not easy to dissipate, resulting in insufficient sweat discharge capacity. The fabric is in a wet state for a long time, which also affects the comfort and is easy to breed bacteria. The patent document with publication number CN212194474U discloses a moisture-absorbing and sweat-wicking fabric, which includes a skin-friendly layer, an antibacterial layer, a moisture-absorbing layer, a base fabric layer and a moisture-conducting line connected in sequence. The moisture-conducting line has a wavy structure and runs back and forth through the moisture-absorbing layer and the base fabric layer, and a part of the moisture-conducting line is exposed on the outside of the base fabric layer. The above technical solution utilizes moisture conducting lines to transfer the moisture absorbed in the moisture absorption layer to the outside of the base fabric layer and dissipate it, thereby accelerating the drying rate of the moisture absorption layer and achieving a perspiration effect. However, the moisture transport capacity of the moisture absorption line is limited, and it can only rely on a very small part exposed to the outside of the base fabric layer to promote moisture evaporation, and it is still difficult to make the fabric dry quickly. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a moisture absorption and perspiration wicking fabric, which can improve the moisture absorption performance and drying rate of the fabric and improve the comfort of use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A moisture wicking fabric comprises a first base layer, a moisture conducting layer, a moisture absorbing layer and a second base layer connected in sequence; the moisture conducting layer comprises a first convex portion protruding toward the first base layer and a second convex portion protruding toward the moisture conducting layer, the end of the first convex portion is connected to the inner side surface of the first base layer, the end of the second convex portion is connected to the inner side surface of the moisture conducting layer, the first convex portion and the second convex portion are alternately arranged, a first air cavity is formed between the back side of the first convex portion and the moisture absorbing layer, and a second air cavity is formed between the back side of the second convex portion and the first base layer; the moisture absorbing layer is provided with a sweat wicking pore, and the sweat wicking pore is communicated with the first air cavity.

[0007] The utility model is provided with a moisture conducting structure from the first base layer to the second base layer, wherein the hydrophilicity of the moisture absorption layer is higher than that of the first base layer, so that the sweat absorbed by the first base layer will be naturally transferred to the side of the moisture absorption layer through the moisture conducting layer, and in the utility model, the moisture conducting layer is a wavy structure and is formed by the first air cavity and the second air cavity, the evaporation area of ​​the moisture conducting layer is large, the evaporation rate of the sweat in the moisture conducting layer is fast, and the water vapor formed by evaporation can be quickly discharged through the sweat discharge pores on the moisture absorption layer. In addition, when the fabric is compressed or stretched, the first air cavity and the second air cavity can also be deformed and exchange gas with the outside world, further accelerating the discharge of water vapor, thereby achieving rapid drying of the fabric, and at the same time, the moisture conducting structure can also reduce the water content of the first base layer, reduce the situation where the fabric adheres to the skin surface, and improve the comfort of use. In summary, the fabric provided by the utility model has the advantages of fast drying speed and not easy to adhere to the skin surface, and is particularly suitable for summer sportswear.

[0008] Furthermore, the moisture conducting layer is provided with communication pores, which connect the adjacent first air cavity and the second air cavity. The communication pores increase the air circulation rate in the first air cavity and the second air cavity, further increasing the evaporation rate of sweat and the discharge rate of water vapor.

[0009] Furthermore, the end of the first protrusion forms a first connection portion parallel to the first base layer, and the end of the second protrusion forms a second connection portion parallel to the moisture absorption layer.

[0010] Furthermore, the first connection portion is connected to the first base layer through a moisture conductive line, and the second connection portion is connected to the second base layer through an adhesive.

[0011] Furthermore, the moisture-absorbing layer is formed by interweaving the first yarns composed of hydrophilic fibers in warp and weft.

[0012] Furthermore, the moisture conducting layer is formed by weaving the second yarn in warp and weft, and the second yarn comprises a polyester core yarn and a hydrophilic coating yarn spirally wound on the outside of the polyester core yarn. The second yarn is composed of a polyester core yarn with poor hydrophilicity and a hydrophilic coating yarn with good hydrophilicity, and sweat can be transported along the surface layer of the second yarn, while sweat is not easy to accumulate in the core layer, and the water evaporation rate is fast, so that the moisture conducting layer can achieve both moisture conducting effect and fast drying.

[0013] Furthermore, the polyester core yarn is composed of a special-shaped polyester fiber, and the special-shaped polyester fiber includes a plurality of edges and corners, and inner grooves are formed between adjacent edges and corners. The inner grooves of the special-shaped polyester fiber can temporarily store a certain amount of water, thereby improving the moisture conduction effect of the second yarn. However, the polyester fiber itself has poor hydrophilicity. When the water in the outer layer evaporates, the water in the inner groove can gradually transfer outwards, thereby improving the moisture conduction effect of the second yarn while retaining the quick-drying property of the second yarn.

[0014] Furthermore, the outer side of the first base layer is covered with a skin-friendly layer.

[0015] Furthermore, the outer side of the second base layer is covered with an antifouling coating.

[0016] Furthermore, the thickness of the moisture conducting layer is smaller than that of the first base layer and the second base layer. When the moisture conducting layer is thinner, the water evaporation efficiency can be improved, thereby accelerating the drying rate of the fabric.

[0017] In summary, the application of the utility model can achieve the following beneficial effects:

[0018] 1. The utility model is provided with a moisture conducting structure from the first base layer to the second base layer. The sweat absorbed by the first base layer will be naturally transferred to the side of the moisture absorbing layer through the moisture conducting layer. The moisture conducting layer is a wavy structure and forms a first air cavity and a second air cavity. The contact area between the moisture conducting layer and the air is large, the sweat in the moisture conducting layer evaporates quickly, and the water vapor can be easily discharged quickly through the sweat vents, thereby improving the overall drying rate of the fabric.

[0019] 2. When the fabric provided by the utility model is compressed or stretched, the first air cavity and the second air cavity will be deformed and exchange gas with the outside, further accelerating the discharge of water vapor, thereby achieving rapid drying of the fabric.

[0020] 3. The moisture-conducting structure provided in the present invention can make the moisture have a tendency to transfer to the moisture-absorbing layer, thereby reducing the moisture content of the first base layer, reducing the adhesion of the fabric to the skin surface, and improving the comfort of use.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0026] Reference Figure 1 This embodiment provides a moisture wicking fabric, which comprises a first base layer 1, a moisture conducting layer 2, a moisture absorbing layer 3 and a second base layer 4 connected in sequence, a skin-friendly layer 5 is arranged on the outside of the first base layer, and an antifouling coating is arranged on the outside of the second base layer;

[0027] The moisture conductive layer comprises a first protrusion 21 protruding toward the first base layer and a second protrusion 22 protruding toward the second base layer, the first protrusion and the second protrusion are alternately arranged, the end of the first protrusion forms a first connecting portion 211 parallel to the first base layer, the first connecting portion is connected to the first base layer through a moisture conductive thread weaving connection, a first air cavity 212 is formed between the back side of the first protrusion and the moisture absorption layer, the end of the second protrusion forms a second connecting portion 221 parallel to the second base layer, the second connecting portion is connected to the second base layer through an adhesive, and a second air cavity 212 is formed between the back side of the second protrusion and the first base layer. The first air cavity 212 and the second air cavity 222 are provided in the present embodiment, so that the evaporation area of ​​the moisture conducting layer is greatly increased, and the evaporation rate of moisture is accelerated when the moisture is transferred from the moisture conducting layer to the moisture absorbing layer. The exchange air holes 23 can accelerate the air circulation in the air cavity, promote the evaporation of moisture and the discharge of water vapor, and the formed water vapor can be discharged to the outside through the sweat venting holes 31;

[0028] The hygroscopic layer is formed by interweaving the first yarn composed of hydrophilic fibers in warp and weft. Figure 2 The moisture conducting layer is formed by weaving the second yarn 24 composed of a polyester core line 241 and a hydrophilic coating line 242 wrapped around the outer periphery of the polyester core line. Since the hydrophilicity of polyester fiber is not good, the hydrophilicity of the moisture absorption layer is greater than that of the moisture conducting layer, so that the moisture absorbed by the first base layer will be transferred to the moisture absorption layer through the moisture conducting layer, on the one hand, the moisture is accelerated to evaporate through the moisture conducting layer, and on the other hand, the moisture of the first base layer is reduced to avoid the skin-friendly layer from having too high water content, which causes the fabric to adhere to the skin surface; in addition, the second yarn is composed of a highly hydrophilic surface layer and a hydrophilic core layer, so that the moisture can be transported along the surface layer and is not easily accumulated in the core layer, thereby improving the evaporation efficiency of the moisture, achieving both the moisture conducting effect and ensuring the drying rate;

[0029] Reference Figure 3 The polyester yarn 241 is composed of a shaped polyester fiber 243. The shaped polyester fiber includes a plurality of edges and corners 2431 and inner grooves 2432 formed between adjacent edges and corners. The inner grooves can improve the temporary storage capacity of moisture, making it easier for the second yarn to transfer moisture toward the hygroscopic layer. The polyester fiber itself has poor hydrophilicity. When the moisture in the outer layer evaporates, the moisture in the inner grooves can gradually transfer outward, thereby improving the moisture conduction effect of the second yarn while retaining the quick-drying characteristics of the second yarn. The polyester yarn 241 can be composed of a single filament of the shaped polyester fiber 243, or can be formed by twisting and winding a plurality of single filaments of the shaped polyester fiber.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
