Description

一种环保白亚麻双氧漂白工艺
技术领域
本发明属于漂白技术领域，具体涉及一种环保白亚麻双氧漂白工艺。
背景技术
亚麻纤维是一种纯天然纤维，具有吸湿性强，散热透气性好，抗霉防蛀，无静电，无化学成分，以及独特的抑制细菌生长和高效阻隔紫外线穿透的特性。但由于亚麻纤维是以束纤维的形式存在，虽然经过前期的梳理仍有大量的果胶、木质素等非纤维素成分的存在，影响了纺纱效率，所以在纺纱前需要对纤维进行脱胶处理，以提高纤维分裂度，清洁纤维，并能够顺利地纺制纱线。
现有技术中，传统的脱胶工艺是对亚麻粗纱先进行亚氯酸钠处理再用高温双氧水漂白(90℃-100℃)。由于氧漂温度高、时间长，对纤维造成损伤大，同时由于温度高使麻纤维中的蜡质去除太多而造成纤维手感硬，不仅耗时耗电，同时也造成生产成本的上升。
中国专利号201110273595公开了名称为“亚麻短纤维脱胶漂白工艺”的专利，此专利在一般工艺的水洗步骤之前，还依次包括酸洗和亚漂两道工艺步骤，脱胶漂白效果好；但是，此专利的氧漂步骤温度需要85℃-95℃，浸泡45-55分钟，温度高、时间长，对纤维造成损伤大，没有克服现有技术中的上述缺陷。
现有技术中工艺流程长，含有次氯化学残留，加工时间长，消耗能源多等。

(3)双氧漂白；加入双氧水升温反应30min，然后恒温水洗循环10min，溢流19min，排液。
所述步骤(1)的酸液采用硫酸，所述酸液恒温温度为30℃。
所述步骤(1)中的亚氯酸钠的使用温度为40℃。
所述步骤(1)中的硫酸与亚氯酸钠的质量比为5：4。
