METHOD OF FORMING NONWOVEN FABRICS UTILIZING REDUCED ENERGY

摘要

A method for hydroentangling a fabric material moving in a processing direction to form a nonwoven fabric is provided, the method including subjecting the fabric material to one or more hydroentangling jet strips that include one or both of (i) at least one hydroentangling jet strip having a spacing between nozzle orifices of at least about 1200 microns; and (ii) a series of hydroentangling j et strips including a first hydroentangling jet strip and a second hydroentangling jet strip spaced apart in the processing direction, the first hydroentangling jet strip being upstream of the second hydroentangling jet strip in the processing direction and including a plurality of nozzle orifices having a first spacing between nozzle orifices that is greater than a second spacing between nozzle orifices of the second hydroentangling jet strip, the first spacing being at least about 1200 microns.
