PROCESS FOR PRODUCING SURFACE MODIFIED COMPOSITE FIBERS FOR ADSORPTION USING AN INORGANIC FILLER

摘要

PURPOSE: A process of preparing functional composite fibers by grinding an inorganic filler in powdery and melt spinning using the same as an additive and reclaimed thermoplastic resin such as PET and PP as a matrix is provided, which produces composite fibers having excellent bad smell removing property and adsorptive function in a simple manner at low cost. CONSTITUTION: The composite fibers are prepared by a process consisting of grinding an inorganic filler to a particle size of less than 5 micrometer with a ball mill or hammer mill, mixing 5 to 15% by weight of the inorganic filler with polypropylene resin having excellent spinning property and polyester resin to produce a pellet and spinning the pellet at 230 to 250 deg.C, wherein bamboo charcoal and pozzolan are used as the inorganic filler.
