摘　　要：为实现丝光淡碱液高效回收与二次利用,文中测试了四级高效蒸发浓缩碱、丝光淡碱液和NaOH溶液中物质浓度,将碱液应用于棉织物漂白和丝光,并对所获得织物性能进行对比分析。结果表明,丝光淡碱液经过浓缩后,NaOH、Na2CO3和Fe3+浓度分别提高107.8 g/L、3.5 g/L和3.6μg/mL;3种碱液用于纯棉织物漂白时,浓缩碱液H2O2分解率高达85.1%,较淡碱液和NaOH所对应值提高了6.6%和12.3%,使用浓缩碱液漂白织物的白度值最小;丝光淡碱液浓缩后用于棉织物丝光,可提高织物的毛效和钡值,尽管丝光效果略逊色于NaOH碱液,但可满足丝光要求,具备工业应用的潜质。In order to realize efficient recovery and secondary utilization of mercerizing alkali liquor,the material concentrations in the concentrated alkali,mercerized light alkali and NaOH solution were measured.The different alkaline solutions were applied to cotton fabric bleaching and mercerization.The properties of the obtained fabrics were also compared and analyzed.The results show that when the mercerizing light alkali was concentrated,the concentrations of NaOH,Na2CO3and Fe3+increased by 107.8 g/L,3.5 g/L and 3.6μg/mL,respectively.In the bleaching process of pure cotton fabric,the decomposition rate of H2O2by concentrated alkali solution is as high as 85.1%,which is 6.6%and 12.3%higher than that of light alkali and NaOH.For these three alkaline solutions,the whiteness value of fabric bleached with concentrated alkali liquor is the lowest.Concentrated alkali liquor can improve the capillary effect and barium value of mercerized fabric.Although the mercerization effect is slightly inferior to NaOH liquor,it meets the mercerization requirements and has the potential for application.
