Abstract
PURPOSE: To utilize the heat energy effectively, solve environmental problems and obtain the titled fibers of high quality, by bringing an atmospheric gas generated in the flameproofing step of organic fibers for carbon fibers into contact with a specific metallic catalyst, and recirculating and reusing the gas.
CONSTITUTION: Organic fibers 9 for carbon fibers, preferably acrylic fibers, are fed to a flameproofing furnace body 1, oxidized in an atmosphere usually containing oxygen, e.g. air, at 200W350°C, and the atmospheric gas containing oxides of textile oiling agents generated by the treatment is passed through an oxidative decomposition catalytic bed 6 consisting of Cr, Mn, platinum, iron, copper and/or Pd, provided in a circulating line of the flameproofing furnace body 1 by a fan 3. The gas is then passed through a heater 5 and duct 4, and returned to the furnace body 1 for reuse to give the aimed fibers 10. The catalyst is preferably supported on a porous inorganic substance, e.g. silica, and the catalyst is preferably CuO, Pt, etc. particularly MnO2.
