Abstract

The invention discloses a water-soluble nanofiber composite non-woven medical beauty material and a preparation method thereof, and belongs to the technical field of non-woven composite materials and preparation thereof. Microfibers and electrostatically spun nanofibers are subjected to spunlacing or needling processing and compounding to form the water-soluble nanofiber composite non-woven medical beauty material; and the electrostatically spun nanofibers are composed of a water-soluble high polymer material and a medical beauty functional material. The advantages are that layering of the composite material is prevented, the structural stability of the material is enhanced, and meanwhile three-dimensional space composition and pore structure of the composite material are effectively regulated and controlled. In addition, the water-soluble nanofibers in the composite non-woven medical beauty material serve as functional substances of the medical beauty material, so that the functional substances can be effectively packaged in the nanofibers in a non-agglomerated state, the mechanical properties of the microfibers and the high-porosity and high-specific surface area structure and surface effects of the nanofibers are fully exerted; and when in use, the functional activity can be triggered efficiently and quickly by simultaneous interaction with the skin and moisture.

Description

technical field [0001] The invention belongs to the technical field of non-woven composite materials and their preparation, and in particular relates to a water-soluble nanofiber composite non-woven medical aesthetic material, and also relates to a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, non-woven medical beauty products belonging to the category of medical treatment and cosmetology have a wide range of production space. The preparation of non-woven medical beauty products through surface coating, impregnation and other finishing is currently a commonly used technical means. However, problems such as poor compatibility between functional substances and substrates, agglomeration of functional materials, and decreased air permeability and mechanical properties of nonwoven fabrics after treatment still restrict the development process of medical aesthetic nonwoven materials. [0003] With the contin...
