A METHOD FOR PREPARING MELTBLOWN WEB COMPRISING AEROGEL

摘要

The present invention relates to a method for manufacturing meltblown web containing aerogel evenly existing among microfibers which comprise the meltblown web. Provided is a method for manufacturing meltblown web containing aerogel, spraying the aerogel on a resin fiber which is sprayed from a nozzle to a collector; or spraying the aerogel and the resin fiber together from the nozzle by injecting the aerogel into air or steam fluid. Obtained is the meltblown web containing the hydrophobic aerogel which is firmly and evenly combined among the resin fibers when the resin fibers are magnetic coupling after the thermoplastic resin fibers and hydrophobic aerogel are laminated on the collector. The meltblown web shows an even physical property, such as, thermal insulation, heat insulation, adsorption, and/or noise absorption, in general by the micro fibers and hydrophobic aerogel which are evenly integrated.
