Abstract

Non-wovens are commonly used as substrates for facial masks. To meet the requirements of low-carbon and environmentally friendly developments, natural, degradable fibers were usually used as facial mask materials. Natural Pomegranate peel extract (PPE) has good antimicrobial and antioxidant properties, which could be used as functional additives. Herein, PPE was blended with Polylactic acid (PLA) to prepare the PPE functional PLA fibers (PLAF) by melt polymerization spinning. The composite non-woven fabric was prepared by PLAF and regenerated cellulose (RC) fibers with different weight ratio. A systematic study of the mechanical properties and air permeability revealed that the mask substrate had excellent mechanical properties as well as air permeability (3324.95 mms−1). Moisture permeability and water absorption test showed that water vapor transmission rate is 163.73 g/m2/h and a water absorption rate is 6.53% with the RC/PLAF blending ratio of 40/60. Furthermore, the deficiencies of RC (e.g., low wet strength, wet modulus) were overcome by enhancing the properties of the composite non-woven. More importantly, the PLA fibers modified by PPE enabled the RC/PLAF-based mask substrate to exhibit good antibacterial, antioxidant and biodegradability properties. These performance advantages and the facile fabrication process provide a new strategy for the development and large-scale generation of dry, compressible and portable facial mask substrates.
