Abstract

The invention provides a high-elasticity nano-fiber multi-component composite non-woven material and a preparation method thereof. The high-elasticity nano-fiber multi-component composite non-woven material comprises a substrate layer, wherein an elastic layer, a soft layer, a hydrophilic layer and an anti-bacterial layer are successively arranged on each of two sides of the substrate layer from inside to outside; each elastic layer is prepared by adding elastic masterbatches in polypropylene fibers through spinning. The high-elasticity nano-fiber multi-component composite non-woven material has good elasticity, flexible comfort and hydrophilic performance; the properties of the high-elasticity nano-fiber multi-component composite non-woven material are as follows: transverse strength is greater than or equal to 30 N, longitudinal strength is greater than or equal to 40 N, elongation is greater than or equal to 200%, softness is smaller than or equal to 32 mN, and PH value is 6-7.

Description

technical field [0001] The invention belongs to the field of non-woven materials, and in particular relates to a multi-component composite non-woven material of high elastic nanofibers 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 and so on. 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 ...
