Antistatic polyamide fiber containing sulfonic acid polyether reaction product

Abstract

Abstract 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. SAID HIGHER VISCOSITY IS A PRIMARY REQUIREMENT FOR IMPROVED DISPERSION OF THE ANTISTATIC ADDITIVE INTO MOLTEN POLYAMIDE DURING SPINNING OF ANTISTATIC FIBER. MOREOVER, IT HAS BEEN FOUND THAT THE ANTISTATIC PROPERTIES AND DYEABILITY OF THE POLYAMIDE FIBER ARE IMPROVED. R-SO3-Z OR A COMPOUND OF THE FORMULA: (R-SO3)N-METAL WHERE A IS A DIVALENT RADICAL. IT HAS NOW BEEN FOUND THAT THE VISCOSITY OF SAID CHAINEXTENDED POLYMERIC REACTION PRODUCT CAN BE SUBSTANTIALLY INCREASED BY REACTING IT WHICH A COMPOUND OF THE FORMULA: -CO-A-CO- AND -CO-NH-A-NH-CO- IT HAS BEEN SUGGESTED THAT THE ANTISTATIC PROERTIES OF SYNTHETIC FIBERS OF POLYAMIDE COULD BE IMPROVED BY DISPERSING THE THE POLYAMIDE A MINOR PROPORTION OF A CHAINEXTENDED POLYMERIC REACTION PRODUCT OF (1) A HIGH MOLECULAR WEIGHT POLYETHER COMPOUND THAT IS AN ADDUCT OF AN AMINE HAVING AT LEAST ONE PRIMARY GROUP WITH AT LEAST ONE ALKYLENE OXIDE HAVING 2 TO 4 CARBON ATOMS, WITH (2) A CHAIN EXTENDING COMPOUND SELECTED FROM THE GROUP CONSISTING OF DIEPOXIDES AND COMPOUNDS WHICH YIELD THE FOLLOWING RADICALS:
