Abstract
An antibacterial and antiviral degradable mask and a manufacturing method thereof are provided. From outside to inside, the mask sequentially comprises a surface layer (), a core layer (), and an inner layer () that contacts the face; the surface layer () is made of an antibacterial and antiviral cellulose spunlace non-woven fabric; the core layer () is made of a polypropylene melt-blown non-woven fabric; the inner layer () is made of a polypropylene spunbond non-woven fabric or a degradable natural cotton fabric. The mask can have both antibacterial and antiviral functions; moreover, the material is degradable, and thus, environmental pollution pressure caused by non-degradable petroleum-based fiber materials such as polypropylene can be effectively relieved.
