Antistatic polyamide fiber containing sulfonic acid polyether reaction product

Abstract

Abstract IT HAS BEEN SUGGESTED THAT THE UTILITY OF SYNTHETIC FIBERS OF POLYAMIDE COULD BE INCREASED BY DISPERSING IN THE POLYAMIDE A MINOR PROPORTION OF AN ANTISTATIC POLYETHER COMPOUND DERIVED FROM THE REACTION OF AN AMINE HAVING AT LEAST ONE PRIMARY GROUP WITH AT LEAST ONE ALKYLENE OXIDE HAVING 2 TO 4 CARBON ATOMS, E.G., A COMPOUND REPRESENTED BY THE FORMULA: H-(O-CH2-CH2)Y-(O-CH(-CH3)-CH2)C-N(-(CH2-CH(-CH3)-O)D- (CH2-CH2-O)Z-H)-CH2-CH2-N(-(CH2-CH(-CH3)-O)A-(CH2-CH2-O) X-H)-(CH2-CH(-CH3)-O)B-(CH2-CH2-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 ANF 1,000. HOWEVER, WITH INCORPORATION OF THIS ANTISTATIC ADDITIVE IN THE POLYAMIDE, SERIOUS PROBLEMS HAVE BEEN ENCOUNTERED IN MELT-SPINNING DUE TO THE FREQUENT OCCURRENCE OF "DRIPS" OF THE MOLTEN POLYMER AS IT EMERGES FROM THE SPINNERET. IT HAS NOW BEEN FOUND THAT THE OCCURENCE OF SAID DRIPS CAN BE ELMINATED OF GREATLY REDUCED BY REACTING TH ANTISTATIC POLYETHER ADDITIVE WITH A COMPOUND OF THE FORMULA: (R-SO3)N-MENTAL OR A COMPOUND OF THE FORMULA: R-SO3-Z WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF ALKYL, CYCLOALKYL, ARYL AND ARYLALKYL, N IS A WHOLE NUMBER CORRESPONDING TO THE VALENCE OF THE METAL, AND Z IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, AMMONIUM CATION AND SUBSTITUTED AMMONIUM CATION. MOREOVER, IT HAS BEEN FOUND THAT THE ANTISTATIC PROPERTIES AND DYEABILITY OF THE RESULTING POLYAMIDE FIBER ARE IMPROVED.
