Polyamide composition
Abstract
Abstract A POLY(HEXAMETHYLENE ADIPAMIDE) (NYLON 6.6) FIBERFORMING COMPOSITION IS DESCRIBED AS WELL AS THE SHAPED ARTICLES MADE THEREFROM PARTICULARLY FIBERS, WHICH ARTICLES HAVE IMPROVED PHYSICAL AND CHEMICAL PROPERTIES. THE NYLON 6.6 COMPOSITION IS A COPOLYMER OF PRIMARILY HEXAMETHYLENE ADIPAMIDE AND A SMALL BUT EFFECTIVE AMOUNT OF AN W-AMINOCARBOXYLIC ACID OR A DERIVATIVE THEREOF. THE AMOUNT OF W-AMINOCARBOXYLIC ACID, OF WHICH E-CAPROLACTAM IS MOST PREFERRED, COPOLYMERIZED WITH THE HEXAMETHYLENE DIAMMONIUM ADIPATE IS LESS THAN THAT WHICH SUBSTANTIALLY AFFECTS NORMAL NYLON 6.6 CHARACERISTICS YET IS SUFFICIENT TO IMPROVE PROCESSIBILITY THROUGH SPINNING, DRAWING AND BEAMING, DYE UNIFORMITY, AND MECHANICAL QUALITY. THE CONTINUOUS POLYMERIZATION OF THE PRESENT COMPOSITION IS ALSO DESCRIBED AS WELL AS THE METHOD OF SPINNING SAID COMPOSITIONS.
