METHOD FOR MANUFACTURING NON-WOVEN FABRIC AND DEVICE FOR MANUFACTURING NON-WOVEN FABRIC
Document Type and Number:
WIPO Patent Application WO/2019/106964
Kind Code:
A1
Abstract:
Provided is an energy-saving and space-saving manufacturing method with which it is possible to manufacture a non-woven fabric of which the bulkiness is recovered in a substantially uniform manner in the thickness direction. This manufacturing method involves heating a non-woven fabric (1) that has a first surface (1a) and a second surface (1b) reverse thereto to recover bulkiness, and thereby manufacturing a bulkiness-recovered non-woven fabric. The manufacturing method is provided with: a heating step for heating, through use of a heating roll, the first surface of a non-woven fabric wound such that the first surface comes in contact with the outer circumferential surface (11a) of the heating roll (11) while the non-woven fabric is conveyed in a conveyance direction (MD); and a blowing step for blowing hot air against and heating the second surface through use of a hot air blowing unit (21) in a region of the non-woven fabric where the first surface is in contact with the outer circumferential surface of the heating roll and being heated.
