基于甘油-亚铁络合物的苎麻织物氧漂工艺研究OA
Study on oxygen bleaching process of ramie fabric based on glycerol-ferrous coordination compound
针对苎麻传统氧漂工艺中碱性强、织物损伤严重等问题,制备了甘油-亚铁络合物(G-Fe2+)水溶液,将其用于苎麻织物近中性的氧漂工艺.通过测试不同催化剂用量和漂白温度对双氧水的分解率及苎麻织物氧漂效果,明确了G-Fe2+对双氧水的催化作用.采用单因素和响应面试验研究了不同工艺对苎麻漂白效果的影响.结果表明:G-Fe2+能够高效催化双氧水;漂白效果优化工艺条件为漂白温度90℃,漂浴pH值5～6,G-Fe2+质量浓度0.6 g/L,漂白时间50 min;优化工艺处理的苎麻织物白度为82.47,断裂强力为514.26 N,白度较原苎麻织物提高22.27%,强力较传统处理工艺提高10.03%.
Aiming at the issues of strong alkalinity and severe fabric damage in the traditional oxygen bleaching process for ramie,the glycerol-ferrous complex(G-Fe2+)aqueous solution was prepared for the near-neutral oxygen bleaching process of ramie fabric.The catalytic effect of G-Fe2+on hydrogen peroxide was clarified by testing the decomposition rate of hydrogen peroxide and bleaching effect of ramie fabric at different catalyst dosage and bleaching temperature.The influence of bleaching process parameter on the bleaching effect of ramie was studied by single factor and response surface experiments.The results showed that the G-Fe2+can effectively catalyzed hydrogen peroxide.The optimum process conditions for bleaching effect were as follows:bleaching temperature was 90℃,bleaching bath pH value was 5～6,mass concentration of G-Fe2+was 0.6 g/L,bleaching time was 50 minutes.The whiteness of ramie fabric treated under the process could be reached to 82.47,the breaking strength was 514.26 N,the whiteness was 22.27%higher than untreated ramie fabric,and the breaking strength was 10.03%higher than the traditional bleaching process.
