PREPARATION OF POLYESTER FIBERS HAVING EXCELLENT ANTIBACTERIAL AND DECORIZING PROPERTIES

摘要

A antibacterial major compd., which is mainly 4th grade ammonium salt using organic silicone as a carrier, is formulated 0.05-5 wt.% as applicable amount per treated fiber. A durability-improving agent is composed of modified silicone compd., fatty acid salt surfactant, and is formulated 20-60 wt.% or 10-40 wt.% respectively per major compd. A cross linking agent is amino silane compd., and used 3-20 wt.% per major compd. The mixed solution of antibacterial compd and two assisting agents are diluted with water. Then the polyester fiber is impregnated or sprayed by the diluted solution and heated at 90-170 deg.C for 10-30 min. This process enables polyester fiber to be crosslinked or ion-bonded with antibacterial compd.
