Nonwoven sheet and method for manufacturing same

摘要

A patterned spunbonded nonwoven fabric sheet comprising a plurality of spunbonded crimped fibers bonded together at a plurality of bonding points, wherein all fibers of the patterned spunbonded nonwoven sheet are spunbonded crimped fibers, and the sheet The composition of the inner fibers is uneven and preferably varies according to a regular pattern. The invention further relates to a method for forming the patterned spunbonded nonwoven sheet from a flat spunbonded nonwoven sheet starting material. Still further, the present invention relates to the above flat spunbonded nonwoven sheet starting material.
