| Abstract:In this article, the feasibility of application of poly-lactic acid fibers in wet-laid nonwoven materials manufacture by using papermaking process was discussed. Mixed fibers combination including monocomponent PLA fiber- bicomponent PLA fiber, monocomponent PLA fiber-low melting point PET fiber, monocomponent PLA fiber- bicomponent PLA fiber-water soluble PVA fiber, and monocomponent PLA fiber-low melting point PET fiber- water soluble PVA fiber were used. The results indicated that monocomponent PLA fiber had difficulty in the preparation of paper because of its high melting temperature; When monocomponent PLA fiber was mixed with bicomponent PLA fiber, PET fiber, PVA fiber, they could be effectively bonded because of their low melting temperature. The bonding of PET fiber is better than bicomponent PLA fiber. The paper strength was futher improved because of added PVA fiber. |
