<p>The present invention relates to a method for manufacturing members for an aircleaner of an automobile using waste pulp and fibers discarded from manufacturing factories and contributing to the reduction of production cost and environmental pollution, which comprises cutting 30-55 % by weight of waste pulp, 25-35 % by weight of waste polyester fibers and 20-35 % by weight of waste polypropylene fibers in predetermined length to make a material mixture; homogeneously mixing the material mixture with a small amount of filler and water; dehydrating the homogeneous mixture while uniformly removing on a network-structured belt and passing through a pair of rollers to form a paperboard precursor; drying the paperboard precursor at temperatures of 90-150 °C to form a paperboard until the moisture content of the paperboard becomes 3-10 %; cutting the paperboard in specified shapes; spraying water onto the paperboard; and molding oil-hydraulically the paperboard into members having respective shapes at temperatures of 120-180 °C and under the pressures of 50∩70 kg.f/cm2.</p> |
