Abstract: When from about 0.7 percent to about 3 percent of organic phosphites are coated on nylon fiber, or are added to the polymer prior to spinning, improved dyefastness is achieved compared to an untreated dyed nylon fiber when this fiber is exposed to ozone.

Abstract translation: 当约0.7％至约3％的有机亚磷酸酯涂覆在尼龙纤维上时，或者在纺丝之前加入到聚合物中，与未经处理的染色尼龙纤维相比，当该纤维暴露于臭氧时，可获得改善的耐染色性。

Abstract: AA CONTINUOUS PROCESS AND ITS PRODUCT FOR SPINNING AND DRAWING POLYCARPROAMIDE FILAMENTS IS DISCLOSED. THE METHOD IS THE COUPLED OR CONTINUOUS PROCESS OF EXTRUDING FILAMENTS, COOLING AND APPLYING FINISH, THEN IMMEDIATELY DRAWING THE FILAMENTS. THE IMPROVED RESISTANCE TO OZONE FADING IS ACCOMPLISHED BY FEEDING THE FILAMENTS AFTER THE FINISH APPLYING STEP WITH A HEATED FEED ROLL THROUGH AN AIR COOLING JET TO A COOLED DRAW ROLL AND WITHDRAWING FILAMENTS TO A SECOND DRAW ROLL, THEN WINDING THE FILAMENTS INTO A PACKAGE.
