Processing apparatus for hot-air treatment of fiber constituting nonwoven fabric to produce nonwoven fabric, and processing process for the same

摘要

The present invention provides a processing apparatus and a processing method capable of producing a point-through-air nonwoven fabric wherein hot air is allowed to penetrate through spots of a web or a sheet-like material and fibers at the penetration site are heat-bonded. Specifically, the present invention provides a processing apparatus for hot-air treatment nonwoven fabric, comprising: a rotating running endless belt with holes, a hot-air blowing apparatus which blows out hot air from an internal side of the endless belt with holes toward an outer side thereof, and an endless belt for fiber conveyance which is arranged on a side opposite to the hot-air blowing side of the hot-air blowing apparatus across the endless belt with holes and rotates with passing the hot-air therethrough.
