Problems solved by technology

Coupled with the contamination of dirt, dust and bacterial particles in the external environment, the fabric is prone to become a breeding area for bacteria in a humid and high-temperature environment. Over time, it will produce odor, and in more serious cases, it may even cause Skin diseases or other infectious diseases, and through other infectious agents, such as touching other people's clothes or washing many people's clothes together in the washing machine, will lead to contact infection. Therefore, the development of antibacterial fabrics has also emerged accordingly. The general practice of antibacterial fabrics It is mainly divided into two types, one is the spinning method, and the other is the post-processing method. The spinning method is mainly to prepare a uniform solution with antibacterial agents, and use solution spinning or melt spinning to spin the spinneret. Fine pores are extruded to form fibers. This method easily aggregates inorganic particles with antibacterial effects, resulting in difficulty in spinning and concentration of stress. The post-treatment method is to apply antibacterial agents by vacuum evaporation (PVD), dipping and spraying, etc. To the surface of the fabric, a layer of silver film is formed, a small amount of silver is deposited on the surface of the fiber, or the antibacterial agent is mixed into the fiber by chemical plating (CVD), by adsorption on the surface, coating in the fiber or treatment with an adhesive It has an antibacterial effect, relying on nano-silver or free silver ions to bind to protein molecules on the surface of bacteria to inhibit the metabolism of bacteria to achieve antibacterial purposes. Among them, the chemical plating method has the strongest binding force between fibers and metallic silver, and the best washing resistance. However, these methods still have the disadvantages of complex process, uneven antibacterial effect and short antibacterial timeliness
[0004] In the past, due to the monotonous color of silver-plated fiber, it is easy to oxidize and change color when exposed to high temperature, which affects the appearance of the fabric, so its application is greatly restricted.
[0005] In the prior art, traditional fibers have good wrinkle resistance, but poor moisture absorption and sweat absorption and quick-drying functions. Since most of them are hydrophobic fibers, in the absence of hydrophilic groups and tight molecular chain structures, The finished clothing has the disadvantages of poor hand feeling, pilling, poor air permeability, no moisture absorption, quick drying and perspiration, which makes people feel uncomfortable after wearing it. As for natural fiber fabrics, such as pure cotton fabrics, which have good moisture absorption, However, after moisture absorption, it will often lead to a close-fitting effect, making consumers feel uncomfortable; and general chemical fiber fabrics have poor hygroscopicity, and sweat stains cannot be effectively discharged during wearing, resulting in a stuffy feeling. In poor cases, even microorganisms may be produced. , multiply rapidly on fabrics and cause skin diseases

Abstract

The invention discloses antisepsis fabric, relates to composite antisepsis fabric and particularly relates to fabric which can resist bacteria in a long-acting mode, absorb moisture and dry rapidly and has one hydrophilic face and one water-proof face. The fabric which can resist bacteria in the long-acting mode is characterized by being formed by weaving hydrophilic yarn with antisepsis agents and hydrophobic yarn. Thus, the fabric has the inner layer and the outer layer, the inner layer of the fabric is hydrophilic and the outer layer of the fabric is hydrophobic.

Description

technical field [0001] The invention belongs to the antibacterial field and relates to a fabric, in particular to a composite antibacterial fabric. Background technique [0002] With the gradual improvement of people's living standards, the requirements for the quality of clothing are also higher, not only requiring comfort, but also having multiple functions. According to different life styles, the functions of the clothes worn are also different. The environment is low temperature, rainy, and exposed to ultraviolet rays in high mountains, so the clothing worn must have functions such as heat preservation, waterproof, and anti-ultraviolet rays; when performing outdoor sports, fabrics that are lightweight, moisture-wicking, quick-drying, and breathable are required , while the traditional knitting fabrics used in sports series mostly use ordinary circular cross-section polyester low-elastic yarn raw materials, using the original dyeing process, more floating colors after was...
