technical field

The utility model relates to the technical field of light industrial textiles, in particular to an antiviral and antibacterial unidirectional moisture-conducting functional fabric.

Background technique

With the improvement of living standards, people pay more and more attention to a healthy lifestyle. Sports and outdoor products have become a booming market at home and abroad. As outdoor sports enthusiasts, quick-drying clothes have always been favored. Although quick-drying clothes can quickly transfer sweat to the surface of the clothes and evaporate the sweat through air circulation to keep the body dry, the fabric is easy to breed bacteria due to excessive sweat flow. It does not have antibacterial effect, nor can it resist the invasion of foreign viruses and bacteria.

At present, the existing antibacterial or antiviral fabrics on the market only have a single function; the same unidirectional wet-conducting fabric also has only a single function. Fabric products have only one function, and the effect is relatively single, which cannot meet the requirements of the wearer.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present utility model, the accompanying drawings that need to be used in the description of the embodiments will be briefly introduced below, wherein:

FIG. 1 is a schematic diagram of a layer structure of a preferred embodiment of the present invention.

Detailed ways

The present utility model will be further described below with reference to the accompanying drawings and specific embodiments. The terms such as "up", "down", "left", "right", "middle" and "one" quoted in the preferred embodiment are only for the convenience of description and are not used to limit the present invention. The practicable scope and the change or adjustment of the relative relationship thereof shall also be regarded as the practicable scope of the present invention without substantially changing the technical content.

Please refer to FIG. 1 , an antiviral and antibacterial unidirectional moisture-conducting fabric designed by a preferred embodiment of the present invention mainly includes: a fabric surface layer 1, an antibacterial protective layer 2, a yarn connecting layer 3, which are sequentially arranged from the outside to the inside. The waterproof and drainage layer 4 and the inner layer 5 of the fabric will be described in detail below.

The surface layer 1 of the fabric is a fabric formed by knitting plain needles of antiviral and antibacterial yarns, and the antibacterial protective layer 2 is also a fabric formed by knitting plain needles of antiviral and antibacterial yarns, which plays the role of double antiviral and antibacterial protection. Various colors or/and patterns can be added through jacquard, digital printing, etc. to enhance fashion and beauty. The antiviral and antibacterial yarn is treated by graft modification, so that the fabric has antiviral and antibacterial functions, and bacteria and viruses are quickly killed upon contact. Through the methods of graft modification and chemical modification, the antiviral groups and antibacterial groups are covalently bonded to the OH-hydroxyl and NH3-amine groups of the cotton fiber, and are firmly bonded to the cotton fiber, thereby making the fiber The fabric achieves permanent antiviral and antibacterial effect, and it is resistant to repeated washing without failure. This is a non-dissolving biological antibacterial.

The inner layer 5 of the fabric is a fabric formed by weaving jacquard with modified waterproof cotton yarn. The inner layer 5 of the fabric is in close contact with the waterproof and drainage layer 4 . The waterproof and drainage layer 4 is also a fabric formed by woven jacquard of modified waterproof cotton yarn. The advantages of the double-layer design of the inner layer of the fabric + the waterproof and drainage layer: the mesh interweaving structure is conducive to the faster passage of the sweat in the inner layer of the fabric through the micropores of the waterproof and drainage layer, and is exported from the inside to the outside, and evaporated and diffused in the outer layer; at the same time, the outer layer It is difficult for the moisture or sweat to flow back to the inner layer, making the inner layer close to the skin more dry and comfortable.

Modified waterproof cotton is formed by first treating the cotton yarn with water- and oil-repellent agent, cross-linking agent, etc. to obtain water-repellent yarn, and then interweaving the water-repellent yarn with ordinary yarn in an appropriate proportion. Like polyester or nylon fabrics, the cotton fabrics obtained in this way have lower moisture absorption capacity, so the drying rate is significantly higher than that of ordinary pure cotton (up to twice as much), and the fabrics will not be wetted by sweat. feel uncomfortable. This technology effectively and organically combines the comfort and functionality of pure cotton, so it has more advantages than most chemical fiber functional products.

Since the inner layer is made of modified waterproof yarn that has undergone waterproof treatment, the inner layer of the fabric basically does not absorb water. The inner layer of the fabric and the waterproof drainage layer use the micro grooves on the surface of the cotton fibers to form channels between the fibers during weaving. Capillary phenomenon. The sweat of the human body quickly moves to the surface of the fabric through wicking, diffusion, transmission and other functions, and plays the role of moisture conduction and perspiration. The mechanism of the unidirectional moisture conduction of the fabric is the so-called differential capillary effect, that is to say, when the tightness of the fabric yarn, the density of the fabric, and the types of fibers used in the inner and outer layers of the fabric are the same, and the fiber linear density of the inner layer is greater than that of the outer layer. When the linear density of the fiber is increased, a capillary effect additional pressure difference will be formed between the inner and outer layers of the fabric. Under the action of this pressure difference, the liquid moisture in the fabric automatically diffuses from the inner layer to the outer layer. Therefore, when people sweat while exercising, the inner layer quickly conducts the sweat from the inside to the outer layer, and the inner layer remains dry, so as to achieve instant drying in seconds. It ensures that the inner layer of the clothes is dry and comfortable for the wearer.

The yarn connecting layer 3 is made of moisture-absorbing and quick-drying yarn, which is in the form of a breathable vertical strip, and is used to connect the inner two layers and the outer two layers. When weaving the moisture-absorbing and quick-drying yarn, the double-sided weft knitting machine is used to form the yarn connecting layer through the double-sided tuck structure, and simultaneously connect the surface layer of the fabric, the antibacterial protective layer, the waterproof and drainage layer and the inner layer of the fabric, and connect each layer structure. integrated fabric.

Moisture-absorbing and quick-drying yarn, hygroscopicity refers to the characteristics of adsorbing or absorbing gas phase moisture on the surface or inside of the fiber, and hygroscopicity refers to the characteristics of the fiber to release moisture to the external environment after absorbing moisture. When the water is discharged in time, it can quickly absorb the moisture and sweat on the surface of the skin, and discharge it to the outer layer to evaporate, keeping the body dry.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Any person skilled in the art, within the scope of the technical solution of the present invention, can Substantially any brief modifications, equivalent changes and modifications made to the above embodiments still fall within the scope of the technical solutions of the present invention.
