发明名称 Face mask having excellent usability
摘要 A face mask folded and having one or more knob portions projecting outward, is characterized in that a cellulose nonwoven fabric with a basis weight of below 60 g/m<2 >is used as a main sheet base material. The nonwoven fabric is reinforced by mixing synthetic fibers or by superimposing on one side or interposing a film. The nonwoven fabric has an elongation percentage of 30% or less at a tensile stress of 3.9 N/5 cm when being wetted, and a relative bending resistance of 5 mN.cm or less. The face mask is impregnated with a facial pack lotion, the viscosity of which is within the range of 0.5 to 10 Pa.sec, in an amount of 50% by weight or more based on the sheet base material.
