Abstract: PURPOSE:To remove the clogging material from a sintered metallic filter, to achieve the moderate cooling of the spun filaments in spinning process, and to prevent the mutual welding of the filaments, by immersing a sintered metallic filter in an alkaline solution, neutralizing with an acid solution, and cleaning with steam. CONSTITUTION:In the melt-spinning of polyester fiber, a sintered metallic filter is used to straighten the flow of gas for cooling the filaments extruded from the spinneret. The filter is immersed in an alkaline solution (preferably 0.05-0.5N caustic soda solution) usually at room temperature -80 deg.C for 0.5-5hr. The filter is then immersed in a solution of an acid such as sulfuric acid, hydrochloric acid, etc. (preferably 0.05-0.5N concentration) preferably for 1-60sec to neutralize the attached alkali. The treated filter is washed with water and cleaned with steam.
