应用Erionyl系列弱酸性染料,分别采用传统工艺和原位矿化工艺对锦纶织物进行染色加工.对比了采用不同染色工艺的耗水量、排放残液的化学需氧量(CODC)r、染品色牢度及各项物理性能指标,结果表明:与传统工艺相比,采用原位矿化工艺对锦纶织物进行染色加工,染色节水率高达80％;排放染色废水中CODer显著降低;不同工艺的染色织物颜色深度和各项色牢度基本一致;采用原位矿化工艺染色的织物断裂强力及断裂伸长率略优于传统工艺.“,”Using Erionyl series of weak acid dyes,the polyamide fabrics were dyed by traditional process and in-situ mineralization process respectively.The water consumption,CODCr concentration of effluent residue,color fastness and physical properties of the fabrics dyed by two processes were compared.The results showed that compared with the traditional process,the dyeing water saving rate of polyamide fabrics that dyed by in-situ mineralization process was as high as 80％,and the concentration of CODcr in the dyeing wastewater was significantly reduced.The color depth and color fastness of dyed fabrics in different process were basically the same,but the breaking strength and breaking elongation of fabrics dyed by in-situ mineralization process were slightly better than those of traditional dyed fabrics.
