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.

The application relates to a process for forming a nonwoven composite. The process includes forming a lofty nonwoven layer, obtaining a thermoplastic polymer, and applying the thermoplastic polymer to the second surface of the nonwoven layer, where the thermoplastic polymer is in the form of a molten polymer, semi-molten polymer, or solid film. Next, pressure and optionally heat is applied to the nonwoven layer and thermoplastic polymer, where the thermoplastic polymer and the second surface of the nonwoven layer are subjected to a textured surface forming a plurality of peak regions and a plurality of valley regions in the second surface of the nonwoven layer and embedding a portion of the primary fibers from the nonwoven layer into the thermoplastic polymer within the valley regions. The thermoplastic polymer is cooled forming a thermoplastic film and the nonwoven layer which together form the nonwoven composite.
