PROCESS FOR PRODUCING RAW MATERIAL FOR PAPERMAKING OBTAINED RAW MATERIAL FOR PAPERMAKING AND HEAT-RESISTANT ELECTRICAL INSULATING SHEET MATERIAL OBTAINED USING SAID RAW MATERIAL

摘要

The present invention is formed of a fibrid formed of aromatic polyamide, short fibers, or a mixture thereof, and aramid paper produced through calendering, high pressure spraying, and crushing the aramid paper as a constituent material of papermaking. It's about how. According to this manufacturing method, the raw material for papermaking which can be reused as a raw material for papermaking can be produced without using a calendered aramid paper, a chemical liquid, or the like.
