FILTER MEDIUM FOR AIR FILTER WITH LITTLE OUT GAS

摘要

PROBLEM TO BE SOLVED: To provide a filter medium containing glass fibers as main fibers, which scarcely emits organic out gas components at the time of use for ventilation and has high water repellency and dust trapping capability and sufficient strength and is usable for every purpose such as air conditioning in buildings and semiconductor plants. SOLUTION: The filter medium contains glass fibers as main components and a condensate produced by hydrolyzing an alkoxysilane having at least three alkoxy groups in a molecule and then condensing the hydrolysis products is used as a water-repelling agent mainly containing low molecular cyclic siloxane and emitting no organic out gas to satisfy the aim of the invention.
