Abstract
Inventia se refera la un procedeu pentru modificarea superficiala a fibrelor poliesterice, caracterizat prin aceea ca, în scopul asigurarii unor bune proprietati de hidrofilie, acestea se trateaza cu o solutie de 1,5% celuloza în dimetilsulfoxid la temperatura de 70 degree C, timp de 15 min, dupa care se îndeparteaza excesul de solutie, se toarna metanol pentru precipitarea celulozei pe fibra se spala apoi de metanol pentru îndepartarea urmelor de dimetilsulfoxid si în final se usuca la temperatura de 110 degree C.The invention relates to a process for superficial modification of polyester fibers, characterized in that, in order to ensure good hydrophilic properties, they are treated with a solution of 1.5% cellulose in dimethylsulfoxide at 70 ° C for 15 minutes, then excess solution is removed, methanol is poured to precipitate the cellulose on the fiber, then washed with methanol to remove traces of dimethylsulfoxide and finally dried at 110 ° C.
