ABSTRACT:
The tensile strength of nonwoven fabric made by traversing a fibrous web on an apertured support with fine columnar streams of liquid is increased when the fine columnar streams are divided up into an array of a plurality of rows of streams, instead of a single row, with the streams in each row being staggered from one another and the rows being spaced 10 to 80 mils apart.
