PROCESS FOR PRODUCING CLEANING SHEET

摘要

A net-form sheet (4) and fibrous webs (1a) and (1b) which comprise fibers containing PET and have been superposed on one or each side of the sheet (4) are subjected to hydraulic entangling to intertwine the constituent fibers of the fibrous webs with one another and entangle the constituent fibers of the fibrous webs with the net-form sheet, whereby a laminate (6) is obtained.  Subsequently, hot air having a temperature which exceeds the glass transition temperature (Tg (°C)) of the PET and is lower than [Tg (°C) + 70°C] is blown against the laminate (6) by the air-through method.  It is preferable that the constituent fibers of the fibrous webs (1a) and (1b) be entangled with the net-form sheet (4) to obtain a laminate (6) and this laminate (6) be dried with hot air, before hot air is blown against the laminate (6) by the air-through method.
