该文通过打小样试验，挑选适用于碱性染色工艺和弱酸性染色工艺的两种不同染料各九支，并结合实际生产中大部分染厂所用工艺，应用三种不同工艺对涤纶织物进行上染，收集染色残液测量pH和COD．使用碱性染色工艺，染液在织物上染前后pH值有变化，残液pH值达到GB4287—92中的相关规定；使用弱酸性染色工艺和染厂所用工艺，染液在织物上染前后pH基本没有变化．对比三种工艺收集残液的COD值，发现使用碱性染色工艺的分散染料，收集的残液COD明显偏低。这为大生产中印染厂优化染色工艺、节能减排、降低综合成本提供了试验依据。
該文通過打小樣試驗，挑選適用于堿性染色工藝和弱痠性染色工藝的兩種不同染料各九支，併結閤實際生產中大部分染廠所用工藝，應用三種不同工藝對滌綸織物進行上染，收集染色殘液測量pH和COD．使用堿性染色工藝，染液在織物上染前後pH值有變化，殘液pH值達到GB4287—92中的相關規定；使用弱痠性染色工藝和染廠所用工藝，染液在織物上染前後pH基本沒有變化．對比三種工藝收集殘液的COD值，髮現使用堿性染色工藝的分散染料，收集的殘液COD明顯偏低。這為大生產中印染廠優化染色工藝、節能減排、降低綜閤成本提供瞭試驗依據。

Select two different series applicable to alkaline dyeing craft and weak acid dyeing craft, each series with nine dyes.Combined with most practical production craft, use the three different crafts to dye the polyester fiber, then collect dyeing residual liquid to measure pH and COD. The dye liquor pH of alkaline dyeing craft changes after dyeing in the fabric, The pH value of residual liquid comes up to the relevant provisions of GB4287-92; The dye liquor pH of weak acid dyeing craft and practical production craft changes a litter Before and after the dye .Contrast the residual liquid COD of the three different crafts, found that the residual liquid COD of alkaline dyeing craft is quite low. This provides experimental basis about Optimization dyeing craft, energy conservation and emission reduction, Reduce the comprehensive cost for dyeing plant.
