Preparation and property study of cool feeling PLA fiber
In order to broaden the application of PLA fiber in clothing,hometextiles,disposable sanitary materials and other fields,three kinds of cool feeling PLA fibers were developed by melt spinning technology through adding natural mineral nano-sized jade powder,high thermal conductivity material aluminum nitride and peppermint essential oil microcapsules in PLA fiber.The mechanical property of the three cool feeling PLA fibers were studied and the fabric cool feeling property were contrasted and analyzed.The results showed that compared with pure PLA fiber,the breaking strength and breaking elongation rate of the fiber were decreased after adding cool feeling reagent,the decrease magnitude of the jade cool feeling PLA fiber was the least.The cool feeling value(qmax)of the three PLA fabric were increased obviously and all have better cool feeling effect.Jade cool feeling PLA fabric has the best cool feeling.
