Problems solved by technology

The above two treatment methods endow the fabric with antibacterial properties, but due to the poor hydrophilicity of chemical fibers, it is easy to cause stuffiness and airtightness during use, and the sweat and other water droplets attached to the surface cannot be diffused in time , will further worsen the experience of use, and even cause symptoms such as skin allergies

Abstract

The invention discloses antibacterial composite cloth and a method for preparing the same, and belongs to the field of functional materials. The antibacterial composite cloth comprises base cloth, anantibacterial composite layer and a protective layer. The base cloth, the antibacterial composite layer and the protective layer are sequentially arranged from top to bottom; the upper surface of thebase cloth is in contact with external environments, the lower surface of the base cloth and the upper surface of the antibacterial composite layer are compressed with each other, and the lower surface of the antibacterial composite layer and the upper surface of the protective layer are compressed with each other. The antibacterial composite cloth and the method have the advantages that the basecloth, the antibacterial composite layer and the protective layer which have different surface properties are matched with one another to form the antibacterial composite cloth, and accordingly the antibacterial composite cloth is excellent in antibacterial property and breathability; the antibacterial composite layer is excellent in hydrophilicity, accordingly, water vapor can be quickly absorbed, can be transferred to the outer surface of the antibacterial composite cloth and can be diffused to external spaces via the upper surface of the base cloth, and the antibacterial composite cloth isbeneficial to absorbing moisture and releasing sweat; broad-spectrum virus killing functions further can be durably realized by silver ions and graphene which are loaded in the antibacterial compositelayer, accordingly, the antibacterial composite cloth can be used for manufacturing breathable and antibacterial medical garments, and suffocation and gas-tight conditions and the like can be prevented.

Description

technical field [0001] The invention relates to an antibacterial composite cloth and a preparation method thereof, belonging to the field of functional materials. Background technique [0002] As a medical fabric, non-woven fabrics have developed rapidly in recent years, and non-woven fabrics are required in many occasions. The non-woven fabric composed of randomly arranged fibers, the size and shape of the holes distributed in it are conducive to the attachment of microorganisms, and become a good parasitic place for the survival and reproduction of microorganisms, and a transfer station for the re-spread of germs. Antibacterial fabrics endow the fabric with antibacterial properties, so that it can efficiently kill or inhibit bacteria, fungi and mold on the fabric, prevent bacteria from regenerating and multiplying, reduce the risk of re-transmission, and improve the safety of normal use and disposal of fabrics. [0003] At present, there are two mainstream processing meth...
