MIXED-FUNCTIONAL POLYESTER FIBER AGGREGATE AND PROCESS FOR PRODUCING THE SAME

摘要

PURPOSE: Provided is a process for producing mixed-functional polyester fiber aggregate which has excellent antibacterial property, far infrared radiative rate, deodorant property, adsorptive rate of heavy metal and heat conservative effect, by mixing charcoal powder with PET to make master batch chip and mix-spinning master batch chip and PET. CONSTITUTION: Mixed-functional polyester fiber aggregate is obtained by a process containing the steps of: preparing master batch chip containing at least 50wt.% of charcoal powder which has 0.2-5.0micrometer of average diameter and not more than 0.5micrometer of size; mixing master batch chip with common PET equally using a special improved feeder; and then melt spinning through a melt extruder. Concentration of charcoal powder in fiber is 1-5wt.%.
