Method for manufacturing functional yarn having deodorization property and quick sweat absorbency

A method for producing a functional yarn having a deodorizing property and a sweat-absorbing and quick-drying property, the method comprising the steps of:

• mixing a polyester having an intrinsic viscosity of 0.70-0.95 dL/g with 1-20 wt %, based on a solid content of yarn fiber, of fine zirconium phosphate inorganic particles having a multiple-layered structure, thereby preparing a master batch chip;
• mixing the master batch chip with a general polyester chip to obtain a mixture, and melting the mixture at a temperature of 250-270° C., thereby preparing a melted polymer;
• and
• melt-spinning the melted polymer through a spinning nozzle having a multi-lobal sectional shape at a spinning temperature of 285-315° C. and an adjusted stretching ratio corresponding to a spinning speed of 2500-4000 m/min,
• wherein the fine zirconium phosphate inorganic particles have a structure in which several tens to several hundreds zirconium phosphate single-layers are superimposed on one another, and the fine zirconium phosphate inorganic particles have a Mohs hardness of 4-6, and
• wherein a plurality of hydrogen atoms are bonded between adjacent layers of the multiple-layered structure.
