A Study of Antibacterial and Aromatic Fibers Vsing Microencapsulation of Antibiotics and Perfume (1) -Microencapsulation of Antibiotics/Perfume-

항균제 및 향료의 마이크로캡슐을 이용한 항균 . 방향섬유에 관한 연구(1) -항균제/향료의 마이크로캡슐화 -

Microcapsules containing 2, 4, 4'-trichloro-2-hydroxydiphenyl ether and perfumes were prepared by the coacervation using poly (vinyl alcohol) and crosslinking agents. Effects of dispersing agents, core materials, agitating speed and crosslinking agents on microcapsule size were investigated. The mean and deviation of microcapsule diameters decreased with increasing agitation speed. The diameters of m;crocapsules decreased with increasing dispering agent concentration at 6, 000 rpm of agitation speed, but it was not changed at 10, 000 rpm. The dispering effect of PVA is better than that of gum arabic. The slight increase in the diameter of microcapsule was observed when the amount of core material was increased. As the amount of crosslinking agent was increased, the diameter of microcapsule was decreased.
