1.目的和范围1。1本试验方法旨在评估预计可承受频繁洗涤的纺织品在家庭洗涤中耐粉状无氯漂白剂的色牢度。评估了五种家用洗衣机的粉状无氯漂白剂、洗涤剂溶液和研磨作用引起的织物颜色变化。1.2首先用粉状无氯漂白剂确定性能水平，如果发现有影响，则单独用洗涤剂重新测试。可能需要使用纯水清洗，以分离硬度、pH值或氯含量等成分的影响。1.3由于目前可用的粉状无氯漂白剂含有粉状无氯漂白剂以外的成分；例如荧光增白剂、发蓝剂等，评估的是这些化学物质对颜色变化的总体影响。

1. Purpose and Scope1.1 This test method is designed to evaluate the colorfastness to powdered non-chlorine bleach in home laundering of textiles which are expected to withstand frequent laundering. The fabric color changes resulting from powdered non-chlorine bleach, detergent solution and abrasive action of five home launderings are evaluated.1.2 First establish the level of performance with powdered non-chlorine bleach and if an effect is found, then retest with detergent alone. It may be necessary to use a water only wash to separate the effects of components like hardness, pH or chlorine content.1.3 Since the powdered non-chlorine bleaches currently available contain ingredients other than the powdered non-chlorine bleach; such as fluorescent whitening agents, bluing, etc., it is the total effect of these chemicals on the color change that is being evaluated.
