Abstract

The invention discloses an antimicrobial fabric supported with nano silver core-shell polymer microspheres and a preparation method thereof. According to the preparation method, amphipathic polyethylene glycol-maleic anhydride-octadecylamine (PEG-Ma-OC) is synthesized at first, and the polymerized styrene is emulsified and dispersed by utilizing the hydrophily and lipophilicity of PEG-Ma-OC, so as to obtain core-shell polymer microspheres; and silver is supported on the surface of the core-shell polymer microspheres, thereby achieving the dispersion uniformity of nano silver particles and well solving the agglomeration problem of the nano particles; by utilizing the high surface activity of the antimicrobial fabric on the surface of which the nano silver core-shell polymer microspheres are supported, the nano silver core-shell polymer microspheres are added in the fabric, thereby improving the biocompatibility of the antimicrobial fabric; polystyrene in the inner core is used, so thatthe strength of the fabric is improved, and the washing fastness and weather resistance of the antimicrobial fabric are enhanced; and the preparation process of the antimicrobial fabric is suitable for batch production and is easy to industrialize.

Description

technical field [0001] The invention relates to an antibacterial fabric, in particular to a core-shell polymer microsphere antibacterial fabric loaded with nano silver and a preparation method thereof. Background technique [0002] With the development of human science and technology and the improvement of living standards, people pay more attention to health and environmental protection, and have new requirements for fabrics, that is, while paying attention to the beauty and comfort of fabrics, the environmental protection and hygiene of fabrics Functions put forward higher requirements. Therefore, as a new type of functional fabric—nanoantibacterial fabric has become an important emerging industry and is widely used in many fields such as sewage treatment, building materials, coatings, and medical care. [0003] Nanomaterials are bulk and flake materials with a size of 1-100nm micro-regions, located in the transition zone between atomic clusters and macroscopic objects. ...
