Properties of cotton fabrics finished by olive oil microcapsules

In order to prolong the acting time of olive oil with fabrics,olive oil microcapsules were prepared using gelatin and Arabic gum as wall materials and applied to finish the cotton fabric.The effects of pre-drying and curing temperature and time,and volume ratio of finishing agent to adhesive agent on the properties of the finished fabric were investigated.The olive oil percentage and air and moisture permeability of the finished fabric were tested as well.The results showed that the oil content of finished cotton fabric was up to 2%-5% when pre-drying temperature was 70 ℃,curing temperature was 120 ℃ for 1 min,solid content of finishing agent was 5%,and the volume ratio of finishing agent to adhesive agent was 1∶1.Moreover,the finished fabric had good slow-release property,good air and moisture permeability,and considerable washing fastness,being able to satisfy the common serviceability requirements.
