Abstract

Invenţia se referă la industria textilă, în special la procedeul de obţinere a fibrelor de celuloză.Procedeul include formarea fibrei în baia de precipitare din soluţie de celuloză în aminooxid terţiar, tratarea fibrei proaspăt filate cu o substanţă auxiliar-textilă, care conţine cel puţin două grupări reactive, tratarea termică a fibrei prin iradiere electromagnetică în gama de microunde şi spălarea cu o soluţie-tampon.Rezultatul tehnic constă în mărirea reticulaţiei transversale a fibrei.
