Abstract:
A non-woven mono-component, mono-constituent poly lactic acid (PLA) web is disclosed. The web material is useful for production of infused and brewed beverage filtering media such as tea bags and other pouches and filters. The nonwoven network of PLA fibers in mono-component, mono-constituent configuration provides enhanced liquid infusion properties, superior wet strength and weight properties that surpass current beverage bags and pouches because of its unique composition and structure. The manufacture of Biodegradable Tea and Coffee filter fabrics utilizing PLA powders in place of low melt mono-component, mono-constituent fibers to improve fabric elongation and reduce cost. The addition of a Chlorine scavenger allows preserving the taste and essence of the beverage.
