大麻植物具有各种环保特性，大麻纤维加工不会造成环境破坏，但众所周知，大多数化学操作都有中断可持续生产的风险。正如多项研究所述，与传统竞争对手相比，过乙酸是一种重要的环保漂白剂。在这项研究中，大麻织物采用过氧乙酸、浸染法和浸染法进行漂白。确定了温度、pH、处理时间、浓度对白度值的影响。通过仪器和成像方法研究了漂白过程的影响。还测试了处理过的纤维的物理性能。除过氧乙酸外，还进行过氧化氢漂白以进行比较。对所选样品的漂白废水的 COD 值进行了分析。与轧堆漂白相比，用尽漂白可获得更高的白度值。在过乙酸中获得相当高的白度值（高达 68.13 Stensby 白度指数），而没有明显的纤维损伤。
Hemp plant exhibits various eco-friendly properties and hemp fiber processing does not cause environmental damage, however, it is known that most chemical operations have a risk to interrupt a sustainable production. As stated in several studies, peracetic acid is an important environmental friendly bleaching agent when compared to its conventional competitors. In this study, hemp fabric was bleached with peracetic acid with exhaustion and padding methods. The effects of temperature, pH, process time, concentration on whiteness values were determined. The influences of bleaching processes were investigated via instrumental and imaging methods. Physical properties of the treated fibers were also tested. Besides peracetic acid, hydrogen peroxide bleaching was carried out for comparison. COD values of bleaching effluents were analyzed for selected samples. Higher whiteness values were obtained with exhaustion bleachings than pad-batch bleachings. Quite high whiteness values (up to 68.13 Stensby whiteness index) attained in peracetic acid without significant fiber damage.
