摘要
采用约克夏无碱活性染料NRA系列和弱酸性染料Nylanthrene B组染料对锦/棉交织物进行一浴法染色。分析了染色工艺因素对锦/棉交织物得色及色差的影响，结果表明， NRA系列活性染料适合中浅色染色， pH值=7.0，染色时间30～45 min，染色温度100℃。采用该工艺染色的锦/棉交织物色光稳定，同色性好，各项色牢度均较高，且缩短了工艺时间，降低了生产成本。
The nylon/cotton mixture was dyed with the alkali-free reactive dyes NRA and weak acid dyes＆nbsp;Nylanthrene B series of Yorkshire in one bath process. Factors affecting color yield and color deviation of dyed cotton/nylon mixture were analyzed. The experiment results indicated this dyeing process was suitable for dyeing nylon/cotton mixture in light and medium shades at 100 ℃ for 30-45 minutes at pH = 7. 0. The dyed fabric had excellent union color property and good color fastness , and the process was beneficial to shorten time and save cost.
