Description

Technical field:

[0001] The utility model relates to the technical field of textile fabrics, in particular to a cotton woven fabric with a unilateral moisture conduction function. Background technology:

[0002] As people's living standards improve, the requirements for comfort and various functionalities of clothing fabrics are getting higher and higher. In addition to meeting the basic needs of covering the body, fashion and appearance, the demands for comfort and functionality are also developing in the direction of multi-function and diversification. For example, the accumulation of sweat after sweating will make people feel stuffy. Although most of the chemical fiber fabrics on the market can achieve quick-drying performance, their air permeability is poor, which makes people feel uncomfortable; although cotton fabrics have excellent air permeability and skin-fitting properties, their quick-drying properties are poor, and it is necessary to build a channel to drain sweat in time to keep the skin and underwear dry. Summary of the invention:

[0003] The utility model aims to provide a cotton woven fabric with a unidirectional moisture conduction function, so as to solve the problems of poor air permeability of chemical fiber fabrics and poor quick-drying property of cotton fabrics, and to realize the unidirectional moisture conduction, moisture absorption and quick-drying functions of cotton fabrics.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A cotton woven fabric with a unidirectional moisture conduction function is provided with a fabric body, wherein the fabric body is a cotton woven single-layer fabric having a front and a back side, wherein the front side is a surface layer made of hydrophilic cotton yarn, and the back side is a skin-contacting layer, characterized in that an environmentally friendly waterproof array with a leakage rate of 40%-70% is provided on the skin-contacting layer, and more than two waterproof pattern monomers arranged at equal intervals are provided in the environmentally friendly waterproof array, and the waterproof pattern monomer is made of a waterproof layer.

[0006] The leakage rate of the skin-fitting layer described in the utility model refers to the ratio of the skin-fitting layer area without a waterproof layer to the total area of ​​the skin-fitting layer. The waterproof pattern monomer in the environmentally friendly waterproof array can be one of a circle, a diamond, and a hexagon. The area range is preferably 0.3mm-10mm, and it is arranged discontinuously, so that the non-waterproof area of ​​the skin-fitting layer is continuous.

[0007] The cotton woven single-layer fabric described in the utility model is one of pure cotton fabric, cotton / regenerated cellulose fabric, and cotton spandex elastic fabric. The cotton woven single-layer fabric is a fabric of three basic weaves, namely plain weave, twill weave, and satin weave, and their varying weaves, and does not include joined double-layer fabrics and laminated double-layer fabrics.

[0008] The waterproof pattern monomer of the utility model is obtained by coating thickening combined with fluorine-free waterproofing additive processing, which is the prior art and will not be described in detail.

[0009] Compared with the prior art, the utility model solves the problems of poor quick-drying and moisture conductivity of cotton fabrics. When a person sweats, due to the differential effect formed on the front and back sides of the fabric, the fabric is subjected to less pressure, and the droplets can be guided from the back side to the front side of the fabric through the moisture absorption and perspiration window. The sweat evaporates quickly on the outer layer of the fabric, and the inner layer of the fabric remains relatively dry. In addition, through the method of rotary screen printing, the unilateral moisture conduction function of traditional thin fabrics is realized, providing consumers with thermal and moisture comfortable clothing fabrics.

[0014] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings to make the present invention easier to understand and to facilitate a clearer understanding of the technical concept that the present invention claims to protect.

[0015] like Figure 1 As shown, the fabric body is composed of a base fabric and an additional functional layer, wherein the base fabric is interwoven by warp yarn and weft yarn, the warp yarn is made of pure cotton yarn, cotton / regenerated cellulose yarn or cotton spandex elastic yarn, the weft yarn is made of pure cotton yarn, cotton / regenerated cellulose yarn or cotton wrapped spandex elastic yarn arranged in a staggered manner in rows, and an additional functional layer composed of wrinkle-resistant, waterproof and oil-proof organic compounds is adhered to the warp yarn and / or the weft yarn.

After the fabric is processed and dyed, it is processed with a fluorine-free waterproof additive coating thickening system for round screen printing, and the pattern is as follows Figure 1 As shown, the omission rate is controlled at 58%, and then a baking reaction is carried out, followed by tentering and padding with a hydrophilic softener, and finally a pre-shrinking treatment is carried out to obtain a unidirectional moisture-conducting pure cotton woven fabric.

After the fabric is processed and dyed, it is processed with a fluorine-free waterproof additive coating thickening system for round screen printing, and the pattern is as follows Figure 2 As shown, the omission rate is controlled at 63%, and then a baking reaction is carried out, followed by tentering and padding with a hydrophilic softener, and finally a pre-shrinking treatment is carried out to obtain a unidirectional moisture-conducting cotton / lyocell woven fabric.

After the fabric is processed and dyed, it is processed with a fluorine-free waterproof additive coating thickening system for round screen printing. The pattern is as follows Figure 3 As shown, the omission rate is controlled at 69%, and then a baking reaction is carried out, followed by tentering and padding with a hydrophilic softener, and finally a pre-shrinking treatment is carried out to obtain a unidirectional moisture-conducting cotton / lyocell woven fabric.
