Abstract: PURPOSE: A deodorizing method of acetate fiber is characterized by using a compounding solution containing zinc oxide, silver, silica and an urethane resin, not changing color and mechanical properties by heating and giving excellent washability and sweat fastness. CONSTITUTION: A deodorizing method of acetate fiber is as follows: (a) dispersing 0.1-2% of zinc oxide, 0.1-0.5% of silver, 0.1-2% of silica and 5-20% of a binder resin selected from the group consisting of an urethane resin, an acrylic resin, a polysiloxane resin, a fluoric type resin and a melamine resin into water to manufacture a deodorizing agent; (b) infiltrating the dyed acetate fiber into the deodorizing agent and drying the acetate fiber with a tenter at 90-120deg.C for 1-10min; and then (c) heating the dried acetate fiber with a tenter at 120-180deg.C for 1-10min. to fix active ingredients of the deodorizing agent to amorphous area of the acetate fiber. Pick-up of the deodorizing agent is 50-80%.
