摘　　要：为研究温度在还原剂还原过程中的作用,将传统硫化钠(Na_2S)与环保型还原剂AS/氢氧化钠两种还原体系进行对比,采用浸染工艺,使硫化黑分别在不同温度下对织物恒温染色90 min,并测定了染液还原电位及染色织物K/S值、断裂强力和摩擦牢度等。结果表明,织物K/S值随温度的升高而增大,且AS体系略优于Na_2S体系。在最优染色温度85℃的条件下,AS体系染色织物的K/S值为25.12,耐干摩擦色牢度为4.5级,耐湿摩擦色牢度为3级,强力损失为161.05 N。In order to study the effect of temperature on reduction process, the traditional sodium sulfide （Na2S） reduction system and environment-friendly reducer AS/sodium hydroxide （Na2H） reduction system are selected for comparison. The fabrics are dyed by sulfur black at different temperatures for 90 min with dip dyeing process. The oxidation-reduction potential, K/S value, breaking strength and rub- bing fastness of dyed fabric are determined. The results show that the K/S value increased with the increase of temperature, and the AS system was slightly better than Na：S system. At the optimal dyeing temperature of 85 ℃, the K/S value of dyed fabric with AS system is 25.12, dry rubbing fastness is Grade 4.5, wet rubbing fastness is Grade 3, and strength loss is 161.05 N.
