摘要
采用液体还原染料还原蓝RSN、棕BR和橄榄T对棉织物进行浸轧染色，探讨了保险粉、氢氧化钠和染料用量，以及染色温度和时间对K／S值和颜色特征值的影响。优化的棉织物液体还原染料染色工艺为：还原染料2％（omf），保险粉20g／L，氢氧化钠15g／L，染色温度40～60℃，染色时间40min，染色织物的耐洗和耐摩擦色牢度均达到服用性能要求。
Three liquid vat dyes of Vat Blue RSN, Brown BR, and Olive T are applied to cotton fabrics dye- ing. The effects of concentration of sodium hydrosulfite, sodium hydroxide and vat dyes, dyeing temper- ature and time on dyeing performance and K/S value of cotton fabrics are discussed. The results show that the optimal dyeing process for cotton fabric is sodium hydrosulfite 20 g/L, sodium hydroxide 15 g/L, dyeing at 40-60 ℃ for 40 rain. The color fastnesses to rubbing and washing of the dyed fabrics can meet the reauirements of wear behaviour
