A tufted pile structure having binder concentrated on, through and in the vicinity of the backstitches

摘要

A pile surface structure in which the tufted backstitch elements produced by the tufting operation are held to the lower surface of a backing by an activated binder material concentrated along either the longitudinal or the transverse lines of needle insertion points. The lower face of the backing member between the adjacent lines of needle insertion points is left substantially free of binder. The binder material is applied before tufting in the form of a sheet or a plurality of stripes laid longitudinally along the lower face of the backing member. During tufting each needle passes through the binder material so that binder is disposed between the backstitch elements and the lower face of the backing.
