Antistatic polyester fiber containing polyether
Abstract
Abstract IT HAS BEEN FOUND THAT AN ANTISTATIC FIBER OF POLYAMIDE, POLYESTER, POLYUREA, POLYURETHANE OR POLYSULFONAMIDE CAN BE PREPARED BY UNIFORMLY DISPERSING BETWEEN ABOUT 1 PERCENT AND ABOUT 12 PERCENT BY WEIGHT OF A COMPOUND REPRESENTED BY THE FORMULA: H-(O-(CH2)2)Y-(O-CH(-CH3)-CH2)C-N(-(CH2-CH(-CH3)-O)D- ((CH2)2-O)Z-H)-(CH2)2-N(-(CH2-CH(-CH3)-O)A-((CH2)2-O)X-H)- (CH2-CH(-CH3)-O)B-((CH2)2-O)W-H WHERE A, B, C, D, W, X, Y, AND Z ARE EACH A WHOLE NUMBER AND THE TOTAL OF A, B, C, AND D IS BETWEEN 8 AND 850 AND THE TOTAL OF W, X, Y, AND Z IS BETWEEN 8 AND 1,000. THE COMPOUND HAS A MOLECULAR WEIGHT BETWEEN ABOUT 4,000 AND 135,000 AND THE ETHYLENE OXIDE MOIETY MAKES UP 10 OF 90% OF THE MOLECULAR WEIGHT OF THE COMPOUND.
