Activators of the crosslinking process for polycaprolactam fibers: Activators of the crosslinking process for polycaprolactam fibers. Zabello, S. E.; Romankevich, O. V.; Zhdanovich, E. V.; Yudin, A.There are some reagents with their cas registry numbers 120-18-3 and 25765-51-9 are used in this study. V. (USSR). Khim. Volokna, (5), 26-8 (Russian) 1976. CODEN: KVLKA4. DOCUMENT TYPE: Journal CA Section: 39 (Textiles) On using a crosslinking catalyst capabale of salt formation with the amide groups of dioxolane-formaldehyde copolymer (I) [25765-51-9]-modified polycaprolactam fibers, the main factor influencing the crosslinking degree was the pH of the catalyst soln. Increasing the affinity of the catalyst for the polyamide fiber led to an acceleration effect at higher pH values. The degree of crosslinking of I-modified polyamide fibers at pH 3.7 was 8 and 84% in the presence of .beta.-naphthalenesulfonic acid [120-18-3] and acid Brilliant Red Fast Zh dye [13421-53-9], resp. .
