Abstract

The invention discloses a microencapsulated artificial leather perfume finishing agent and a preparation method thereof. A leather essence comprises, by weight, 0.1-10% of birch tar oil, 0.1-10% of acetyl cedrene, 1-80% of cedarwood oil, 1-80% of santal 208, 0.1-10% of isobutylquinoline, 0.1-20% of ebanol, 0.01-20% of thymol, 0.1-25% of guaiacol, 0.01-20% of indole, 1-10% of vetiver oil, 1-30% ofrhodinol, 1-30% of linalool, 1-50% of linalyl acetate, 1-40% of terpinyl acetate, 1-20% of peppermint oil, and the balance of benzyl benzoate. The leather essence is coated with a polymeric material to prepare the microencapsulated perfume finishing agent, and leather finished and processed with the microencapsulated perfume finishing agent has the advantages of long fragrance depositing time, nopeculiar smell, high product level, environmental protection and safety.

Description

technical field [0001] The invention relates to the technical field of textile finishing agents, in particular to an artificial leather microcapsule fragrance finishing agent and a preparation method thereof. Background technique [0002] Artificial leather is a kind of imitation leather made by dissolving and diluting polyurethane with a solvent, coating it on the base cloth, and then heat-sealing it to make holes. Artificial leather technology is quite mature now. It is difficult to distinguish various artificial leather products from real leather based on vision and feel. Artificial leather is used in a wide range of applications, from furniture to automobiles, and aircraft decoration can be seen everywhere. The manufacturing cost of artificial leather is much lower than that of real leather, and many properties are better than real leather. So from clothing, leather shoes, furniture to airplanes. Car decoration generally uses artificial leather as raw material. Acco...
