NEGATIVE ION-GENERATING MODACRYLIC FIBER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a negative ion-generating modacrylic fiber which uses inexpensive rhyolite and generates negative ions in a practical level amount without an exciting agent such as a radioactive substance. SOLUTION: This negative ion-generating modacrylic fiber is characterized by containing the rhyolite having an average particle diameter of≤3μm and an electrically insulating substance having an average particle diameter of≤1μm. The average particle diameter of the rhyolite is preferably 0.1 to 1μm. The total content of the amphibole and the electrically insulating substance is preferably 2 to 15 wt. %. COPYRIGHT: (C)2004,JPO
