Abstract

The invention provides a nanofiber high-rate hydrophilic non-woven material and a preparation method thereof. The nanofiber high-rate hydrophilic non-woven material comprises a nanofiber antibacterial layer, at least one side of the nanofiber antibacterial layer is provided with a nanofiber antibacterial retention layer and a nanofiber antibacterial hydrophilic layer in sequence from inside to outside, and the nanofiber antibacterial layer is a nanometer polypropylene fiber antibacterial layer. The nanofiber antibacterial hydrophilic layer can improve hydrophilic performance, the nanofiber antibacterial retention layer can further lock water, water loss is prevented, and the hydrophilic rate is increased; in addition, the nanofiber antibacterial layer is the nanometer polypropylene fiber antibacterial layer and has disinfection and sterilization functions. The nanofiber high-rate hydrophilic non-woven material has good hydrophilic performance, and the hydrophilic rate is smaller than or equal to 1,000%.

Description

technical field [0001] The invention belongs to the field of nonwoven materials, and in particular relates to a nanofiber high-magnification hydrophilic 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, papermaking, leather and plastic, and fully combines and uses many modern high-tech. 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 improvement of people's requirements for the quality of life, the comfort of non-woven materials used as disposable products or medical materials is a relatively high con...
