Influencing factors in preparation of disperse dye microcapsules

摘要

Disperse dye microcapsules with double-layered wall were prepared by in-situ polymerization in this paper. The influencing factors on microcapsules particle size, and the content of the microencapsulated disperse dye were discussed. It was found that the mean size of the disperse droplet became smaller with the reduced core/wall ration, increased emulsifier concentration and accelerated emulsion milling speed. While, the content of the disperse dyes in microcapsules decreased with the increased stirring speed of emulsifier.
