摘　　要：针对涤/棉混纺针织物传统染色工艺耗水量大、耗时长、生产效率低等问题,开发涤/棉针织物分散/活性同浴染色新工艺,实现节水降耗且缩短流程。新工艺在分散染料染涤后剩余的残液中加入缓冲剂,使其继续成为染棉所需的工作液,省去了分散染料染涤纶后与活性染料染棉前的环节,缩短了传统涤/棉分散/活性染料染色的工艺流程。结果表明,使用缓冲剂的涤/棉分散/活性染料同浴染色新工艺的色牢度可达到传统工艺的水平,节能降耗,清洁环保,降低了生产成本。In view of high water consumption,long time consumption and low production efficiency of the traditional dyeing process of polyester/cotton blended knitted fabric,new one-bath dyeing process of blended knitted fabric with dispersion/active dyes is developed,which enables the realization of water saving and consumption reduction and short process.In the new process,the buffer is added to the residual liquid after dyeing polyester with disperse dyes to make it continue to be the working liquid required for cotton dyeing.The link after dyeing polyester with disperse dyes and before dyeing cotton with reactive dyes is omitted,and the process flow of traditional disperse/reactive dyes dyeing of polyester and cotton is shortened.The results show that the color fastness of polyester/cotton blended knitted fabric dyed by the new onebath dyeing process with dispersion/active dyes adding buffer agent could reach the quality level of the traditional process.The process saves energy and reduces consumption,is clean and environmentally friendly,and reduces production costs.
