Research progress of nonwovens for medical protective garment

In order to promote the application of nonwovens for medical protective materials, this paper systematically reviewed on the development of nonwovens for medical protective garment as well as on the types and applications of nonwovens as novel protective materials. The preparation methods and protective properties of spun-bonded, meltblown, spunbond-meltblown-spunbond composite and flash spinning nonwovens were introduced, and the mechanisms and characteristics of novel nonwoven protective materials were discussed from three aspects, i.e. film covered nonwovens, composite nonwovens and functional nonwovens, focusing on the influence of structure of different protective materials on the virus blockage, moisture absorption and air permeability. In addition, the applications of intelligent monitoring, temperature or humidity regulation, and selfvdisinfection, self-cleaning intelligent materials in protective garment were described. The future medical protective garments are expected to be developed towards the direction of high protection, high comfort and intelligence.
