Abstract

The invention discloses an antibacterial nano-fiber non-woven material and a preparation method. The antibacterial nano-fiber non-woven material comprises at least two antibacterial nano-fiber layers, a hydrophilic nano-fiber layer is arranged between every two adjacent antibacterial nano-fiber layers, nano-fibers of the antibacterial nano-fiber layers are crossed in the three-dimensional space to form holes with nanoparticles and nano-fiber clusters, and antibacterial nano-silver particles and antibacterial nano-zinc oxide particles are distributed in the holes; the nano-silver particles and antibacterial nano-zinc oxide particles are distributed in the holes with nanoparticles and nano-fiber clusters, and the antibacterial particles cannot fall off easily and act jointly, so that the antibacterial nano-fiber non-woven material has the lasting antibacterial property. Besides, the hydrophilic nano-fiber layer provides the antibacterial nano-fiber non-woven material with the good hydrophilic property. The antibacterial nano-fiber non-woven material prepared with the preparation method can be widely applied to the fields of articles for daily use, medical care, hygienic products for infants and adults and the like.

Description

technical field [0001] The invention belongs to the field of nonwoven materials, and in particular relates to a nanofiber antibacterial nonwoven material and a preparation method thereof. Background technique [0002] Nonwovens are also known as nonwovens, nonwovens, nonwovens, nonwovens or nonwovens. Nonwoven technology is a material processing technology that originates from textiles but surpasses textiles. It combines the four major flexible material processing technologies of textile, paper, leather and plastic, and fully combines and uses many modern high-tech technologies, such as computer control, information technology, high-pressure jet, plasma, infrared, laser technology, etc. Whether in many fields such as aerospace technology, environmental protection, agricultural technology, medical care or people's daily life, non-woven new materials have become an increasingly important product. With the development of science and technology and the improvement of people's ...
