Abstract:
1. A method for producing an anti-bacterial polyester fiber from an anti-bacterial polyester masterbatch, said method comprising: a.) grinding active carbon into micro-particles of 1-1000 micron in size; b.) impregnating the active carbon micro-particles obtained in a.) with a Chinese herbal medicine selected from the group consisting of Radix et c.) air drying the active carbon micro-particles in b.); and dry grinding said dried active carbon micro-particles into finer micro-particles of 1-50 micron in size wherein said finer micro-particles are homogenously dispersed in a solution; d.) binding the finer micro-particles dispersed homogeneously in the solution with a monomer through an esterification reaction to form the anti-bacterial polyester masterbatch; and e.) producing the anti-bacterial polyester fiber from the anti-bacterial polyester masterbatch using a low temperature batch processing chip spinning technique.
