Abstract: The paper first briefly introduced the characteristics of bamboo lyocell fiber and then focused on introducing its application in manufacturing spunlaced mask. By comparing the mechanical property, waterabsorbing ability and softness of bamboo lyocell fiber mask substrate and cupro fiber mask substrate, it’s found out that the former has good moisture-retention and moisture-absorption ability, dimensional stability, softness and skin-friendliness, and it is an ideal material for making mask substrate.

Key words: bamboo lyocell fiber; cupro fiber; spunlace; mask
