摘　　要：选择合适的练染助剂和原位矿化剂，在酸性条件下对涤棉交织或混纺针织物进行精练氧漂染涤纶一浴两步法加T，不排染液直接原位矿化，得到的优化工艺条件：氧漂染涤一浴剂PEL0．5g／L，冰醋酸0．3g／L，27％双氧水6g／L，130℃分散染料同浴高温染色30min，90℃原位矿化20min。该工艺能有效防止涤纶染色料渍，棉白度合格、棉籽壳无残留、质量稳定，残液可再次用于染涤纶针织布或涤棉混纺针织布单染涤纶，续缸生产综合每吨布染色耗水量2-3吨。The suitable scouring and dyeing auxiliaries and in situ mineralization agent are selected, and applied to scouring and peroxide bleaching and polyester dyeing of polyester/cotton knitted fabric in onebath-two-step process under acidic condition. The optimized process is one-bath peroxide bleaching and dyeing agent PEL 0.5 g/L,glacial acetic acid 0.3 g/L,27% hydrogen peroxide 6 g/L, dyeing at 130 ℃ for 30 min with disperse dyes in the same bath, in situ mineralization at 90 ℃ for 20 min. This process can effectively prevent dye stains to polyester. The fabric has stable quality and standard whiteness without cotton shells. The residue dye bath can be re-used for dyeing polyester knitted fabric or polyester/cotton blended knits. The water consumption is 2 to 3 tons per ton cloth in standing dyeing.
