A Facile Method to Fabricate Bioenvironmentally Friendly Janus Nonwoven Medical Covers: Preparation and Property Evaluation


Medical product contamination is a serious threat to patients’ health. However, designing medical covers that ensure Janus performance and outstanding abrasion resistance, mechanical performances has remained a great challenge. In this study, a novel Janus nonwoven fabric nonwoven fabric consists of a hydrophilic inner layer of polylactic acid (PLA)/lowmelting polylactic acid (LPLA) and a coated outer layer of hydrophobic thermoplastic polyurethane (TPU) is successfully fabricated. The subsequent PLA/LPLA-TPU textiles exhibits excellent protective performance of inner absorption. Moreover, the coating improves tensile strength and increases abrasion resistance. A mechanism of mechanical failure is further studied. This kind of nonwoven fabric is suggested to be a promising candidate for medical covers and health supplies.
