The technology of microcapsule was employed in this paper to prepare fragrant microcapsule agent, in which the core material was lavender oil, and the wall materla polyurethane was formed from a reaction with 2, 4-tolylem diisocyanate (TDI) and poly (ethylene glycol) (PEG) by interfacial polymerization method. Through single factor and orthogonal experiments, the optimum technology conditions have been got as follows: the molecular weight of PEG 400, core/wall ration 1 : 2, disperser sodium alginate (SA) 0.15%, emulsifier Poly(vinyl alcohol) (PVA) 1%, emulsifying speed 9 500 r/min, emulsifying time 5 min and reaction time 2 h. The microcapsule fragrant agent, prepared under the optimum conditions, was applied on the fabrics and a kind of good control-released fragrant fabric with health-care function was obtained.
