Abstract: Abstract: In order to prolong the acting time of olive oil in the fabric, olive oil microcapsules were prepared using gelatin and Arabic gum as wall materials in this paper. Olive oil microcapsules prepared self-made were finished on cotton fabric. The effect of pre-drying temperature, curing temperature and time, solid content of finishing agent, the volume ratio between finishing agent and adhesive agent were investigated. Through testing the drug-loading rate of olive oil in cotton fabric, breathable and moisture permeability, the optimum parameters were as follow: pre-drying temperature was 70℃, curing temperature was 120℃ and time was 1min, solid content of finishing agent was 5%, the volume ratio between finishing agent and adhesive agent was 1:1. The oil content of cotton fabric was 2%~5%. Its slow-release property tested with UV spectrophotometer was also good. Breathable and moisture permeability and washing fastness were satisfied to normal needs of fabrics.
