The Preparation and Processing Technology of PLA Superfine Fiber Non-woven Materials

摘要

In view of the disadvantages of superfine fiber nonwovens materials made by polypropylene (PP), such as poor hydrophilcity, deficiency of antibacterial property, poor hand feeling, we chose polylactic acid (PLA) slices as the raw material to make superfine fiber non-woven materials, which is quite antibacterial and very soft. Using a modified superfine fiber processing technology, the preparation of PLA superfine fiber non-woven materials could be easy and effective. The fiber fineness of PLA materials is mainly distributed in 1-5 microns, and the contact Angle of PLA materials is about 50 degrees lesser than that of PP materials. The antibacterial properties of PLA are good enough. We discussed the problems in the process of production and gave some suggestions.
