Abstract

The invention provides a nanofiber high-magnification hydrophilic nonwoven material and a preparation method thereof. The nanofiber high-magnification hydrophilic nonwoven material includes a nanofiber antibacterial layer, at least one side of the nanofiber antibacterial layer is sequentially provided with a nanofiber water-retaining layer, a nanofiber hydrophilic layer, and the nanofiber antibacterial layer is nano-polypropylene. Fiber antibacterial layer. The nanofiber hydrophilic layer of the present invention can improve the hydrophilic performance, and the nanofiber water-retaining layer can further lock water, prevent water loss, and increase the hydrophilic ratio. In addition, the nanofiber antibacterial layer is a nano-polypropylene fiber antibacterial layer, which has antivirus and antibacterial properties ; The nanofiber high-magnification hydrophilic nonwoven material of the present invention has good hydrophilic performance, and the hydrophilic ratio reaches within 1000%.

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...
