Abstract:
A method of making a nonwoven fabric for powered buffing applications, comprising the steps of:providing a precursor web comprising polyester staple length fibers; providing a foraminous, three-dimensional image transfer device having an array of three-dimensional surface elements; positioning said precursor web on said image transfer device, and hydroentangling said precursor web to form an imaged nonwoven fabric having surface irregularities configured to enhance retention of an associated buffing compound, and applying a polymeric binder composition to said imaged nonwoven fabric to provide said fabric with a Combined Tensile Strength of at least about 800 grams/ounce of fabric, said polymeric binder composition comprising a melamine polymeric compound. and an acrylic/copolymer composition, said imaged nonwoven fabric has a Taber Abrasion of at least about 1000 cycles after application of said binder composition.
