Abstract
Disclosed are a method and an apparatus for manufacturing a non-woven fabric, in which a predetermined pattern of a forming body is transferred to a non-woven fabric immediately after or simultaneously with its formation by urging the non-woven fabric onto the forming body with water jets.
Claims8
A manufacturing method of a non-woven fabric comprising the steps of:
- forming a fibrous web on an outer peripheral surface of a circulating wire net transporting belt;
- forming a non-woven fabric by applying water jets to said fibrous web on the outer peripheral surface of said wire net transporting belt for entangling fibers;
- and
- transporting said non-woven fabric for placement opposite to a forming body including a net having a predetermined pattern and encircling a drum body or a plurality of rolls;
- and
- applying water jets to said non-woven fabric from a side of an inner peripheral surface of said wire net transporting belt or another wire net transporting belt following said wire net transporting belt so as to urge said non-woven fabric onto said forming body to transfer said pattern of said net to said non-woven fabric, wherein
- a mesh of said net is sufficiently coarser than a mesh of said wire net transporting belt.

- and
- transporting said fibrous wet for placement opposite to a forming body including a net having a predetermined pattern and encircling a drum body or a plurality of rolls;
- and
- applying water jets to said fibrous web from a side of an inner peripheral surface of said wire net transporting belt so as to urge said fibrous web onto said forming body to simultaneously entangle fibers of said fibrous web to form the non-woven fabric and transfer said predetermined pattern of said net to said non-woven fabric, wherein
- a mesh of said net is sufficiently coarser than a mesh of said wire net transporting belt.
