发明名称 MOLDED PRODUCT WHICH EMITS PERFUME
摘要 PURPOSE:To provide the title molded product which can absorb a large quantity of perfume in a short time, has a large volume shrinkage ratio before and after absorption and does not stain fingers, by allowing a liquid perfume compsn. to be absorbed by a specified porous molded product obtd. by allowing an ethylene/vinyl accetate copolymer resin powder to partially fuse together. CONSTITUTION:An ethylene/vinyl acetate copolymer resin powder having an average particle size of not larger than 1mm and a vinyl acetate content of 6-40wt% is filled in a desired mold and heated at an optimum fusing temp. of lower by -7 deg.C or higher by +4 deg.C than the m.p. of the resin for 25-30min to allow the powder to partially fuse together, thus obtaining a porous molded product having a thickness of about 10mm, a bulk density of 0.4-0.8g/cm<3> and air-permeable open cells. A liquid perfume compsn. consisting of a desired perfume or the perfume and a solvent in an amount corresponding to the wt% of the vinyl acetate content is absorbed by the molded product in such a way that the perfume is not left in the open cells and the apparent volume of the molded product is increased by at least 1.2 times before absorption.
