Webs of Bi-component and Mono-component Co-PLA Fibers

Abstract

Web material for production of tea bags and the like made of a nonwoven network of PLA fibers in mono-component.

1 . An infusion package having a non-woven web, said non-woven web consisting: a mono-component Polylactic Acid (PLA) fiber and derivatives for providing biodegradability after usage and recyclability of waste materials during each step of the manufacturing process from polymer to finished web. 
     
     
         2 . The infusion package as in  claim 1  usable as material for bags or pouches for: lemonade, herbal sachets, coffee, tea, hot chocolate, soap powder, chemicals and chlorine for pools and spas, decontaminating liquids, coloring of liquids, dehumidifying chemicals, carriers for phase-change materials for heating or cooling, tobacco pouches, and all materials that can be placed in a heat and/or ultra sound activated sealable container. 
     
     
         3 . The infusion package as in  claim 1  further including a string attached to the package, said string also made of a mono-component Polylactic Acid (PLA) fiber and derivatives. 
     
     
         4 . The infusion package of  claim 3 , wherein the package is a beverage infusion package. 
     
     
         5 . The infusion package of  claim 3 , wherein the package is a chemical release package. 
     
     
         6 . The infusion package of  claim 3 , wherein the package is an odor release package. 
     
     
         7 . The infusion package as in  claim 1  wherein the crystallinity of the PLA fiber is controlled by drawing the fiber. 
     
     
         8 . The infusion package as in  claim 1  further including a dry basis weight from between about 8 to 85 grams per square meter. 
     
     
         9 . The infusion package of  claim 8 , wherein the package is a beverage infusion package. 
     
     
         10 . The infusion package of  claim 8 , wherein smaller particle size contents may be utilized as compared to particle size of contents in paper infusion packages. 
     
     
         11 . The beverage infusion package as in  claim 1  wherein the pore size of the web if infused with hot liquids to enhance flow.
