Abstract
This invention relates to fibrillated fibers having particular physical characteristics, articles made therefrom as well as methods of producing the same. In particular the fibrillated fibers are defined by their Canadian Standard Freeness in combination with their Tensile Strength when formed into a sheet.
Claims15
A fibrillated monoethylenically unsaturated monomer based fiber wherein said fiber has a Canadian Standard Freeness of less than 100 in combination with a Tensile Strength of at least 5 pounds per inch.
A fibrillated fiber wherein said fiber has a Canadian Freeness of less than about 100 in combination with a Tensile Strength of at least 5 pounds per inch and said fiber is a copolymer of a mixture of monomers comprising acrylonitrile and methyl methacrylate wherein said acrylonitrile contribution comprises at least 85%, by weight, of the monomer mix and said methyl methacrylate contribution comprises at least 10%, by weight, of the monomer mix.
