ABSTRACT:
This invention relates to a method and apparatus for making pile fabrics wherein a sheet of longitudinally striated thermoplastic film formed into loops is fusion bonded to a thermoplastic backing sheet by sonic energy to bond the film to the backing sheet at the lines of contact without loss of orientation in either the striated film or the backing sheet and then subsequently the bonded striated film is fibrillated to separate the loops into individual filaments thereby forming a pile fabric.
