METHOD FOR FINISHING FABRIC BY ADOPTING MOSQUITO REPELLING MICROCAPSULES

摘要

The present invention relates to the field of after-finishing of textile, and particularly relates to a method suitable for durable mosquito-repelling finishing on fabric. The method comprises: first preparing a maleic anhydride grafted polypropylene raw material, then preparing the raw material into spinning yarn by using a melt spinning technology; finishing mosquito repelling microcapsules on the spinning yarn; finally coating a polytetrafluoroethylene coating layer having a micropore structure on finished polypropylene fiber spinning yarn, thus obtaining polypropylene fiber finished and modified by using the mosquito repelling microcapsules; and weaving the finished and modified polypropylene fiber into fabric. By coating a tetrafluoroethylene protection layer outside finished polypropylene fiber, microcapsules can be tightly sandwiched, thereby preventing more effectively the microcapsules from falling off.
