▎ 摘 要
NOVELTY - Preparing slow-release porous aerogel PET masterbatch containing an antibacterial agent involves configuring antibacterial agent solution, preparing porous aerogel, porous aerogels containing antibacterial agents and PET masterbatch containing antibacterial agent slow-release porous aerogel. USE - Method for preparing slow-release porous aerogel PET masterbatch used for the pre-spinning coloring of fibers. ADVANTAGE - The method enables to prepare slow-release porous aerogel PET masterbatch, which can not only color the PET fibers, endows colored PET fibers with excellent antibacterial properties and excellent mechanical properties.
