Sulfo-modified polyesters and shaped structures made therefrom
Abstract
Abstract THE INVENTION PROVIDES FIBER-FORMING, SYNTHETIC LINEAR POLYESTERS COMPRISING, IN ADDITION TO THE USUAL DICARBOXYLIC ACID MOIETY AND DIOL MOIETY, DEFINITE AMOUNTS OF ARALIPHATIC SULFONATED RADICALS OF THE GENERAL FORMULA ME-O-SO2-CH2-AR(-X)-(COO-)N IN WHICH ME STANDS FOR ALKALI METAL, AR REPRESENTS THE BENZENE NUCLEUS X STRANDS FOR HYDROGEN, METHYL OR THE GROUP MEO3S-CH2-AND N IS 1 OR 2 IN THE POLYMER MOLECULE. THE POLYESTER AND THE SHAPED STRUCTURES MADE THEREFROM HAVE A GOOD AFFINITY FOR BASIC DYESTUFFS AND THE DYEINGS OBTAINED ARE VERY FAST TO LIGHT. MOREOVER, THE FILAMENTS AND FIBERS OBTAINED HAVE A LOW FOLDING ENDURANCE AND ARE, THEREFORE, SUITABLE FOR THE MANUFACTURE OF FABRICS HAVING A MINOR TENDENCY TO PILLING.
