Title:
ELECTRET FIBER AGGREGATE
Document Type and Number:
Japanese Patent JP3176972
Kind Code:
B2
Abstract:
PURPOSE: To obtain an electret fiber aggregate capable of keeping high electrostatic potential over a long period and useful for air filter and wiper.
CONSTITUTION: The surface of a synthetic fiber such as polyester, polyolefin or polyacrylonitrile having an equilibrium water-content of <2% and a melting point of ≥150°C is coated with a resin such as polyolefin, ethylene-vinyl acetate copolymer or acrylic acid ester and charged by applying high potential. The surface resin layer acts also as a hot-melt resin.
