These accelerated laundering tests are to evaluate the colorfastness to laundering of textiles which are expected to withstand frequent laundering. The fabric color loss and surface changes resulting from detergent solution and abrasive action of five typical hand or home launderings, with or without chlorine, are roughly approximated by one 45 min test (see 9.2-9.6). However, the staining effect produced by five typical hand or home launderings cannot always be predicted by the 45 min test. Staining is a function of the ratio of colored to undyed fabrics, fiber content of fabrics in the wash load and other end-use conditions which are not always predictable.

When this test method was originally developed, various options of this method were intended to evaluate the color change and staining by five home or commercial launderings, on an accelerated basis. Throughout the years, commercial laundering procedures have changed and commercial cleaning today involves many different types of processes, dependent on the type of product being cleaned that cannot be duplicated by one accelerated laboratory procedure. In 2005, all references to commercial laundering were removed as it is not known if these procedures accurately replicate typical commercial laundering processes used today.

Test Item 测试名称：AATCC 61 耐水洗色牢度

Test Requirement 测试要求：

将试样和贴衬布缝合后，放进耐洗色牢度测试仪罐子，加入洗涤剂，根据不同的洗涤方式调节洗涤液PH值、选择洗涤温度和时间、钢珠数量，拿出试样用水清洗，干燥后评定色牢度等级。

试验目的：用来评定那些需经受多次家庭洗涤的纺织品的色牢度。

测试原理：在合适的温度、洗涤剂、漂白剂及摩擦情况的条件下对试样进行测试，这样其的颜色变化类似于五次手洗、家庭或商业洗涤的情况，颜色变化可可方便地在短时间内测出。

测试步骤：

1 根据标准配置水洗液。
2 设定水洗牢度测试仪的水浴温度。
3 需将500mL或1200mL水洗罐中的洗液或所需钢珠预热到规定温度。
4 将组合试样放入水洗罐内，启动水洗牢度测试仪。
5 运行规定时间后，取出试样组合。
6 用蒸馏水或流动水清洗。
7 干燥组合试样。
8 评级。

Sample Size 样品数量 / 送样规格: A4纸张大小一张
