1.目的和范围1。1本试验方法是一种诊断试验，旨在筛选对氧漂白洗涤剂敏感的染色棉织物。它提供了一个加速程序，以评估染色纺织品在暴露于活性氧漂白剂（模拟多次家用洗涤，通常为10次或更多）时的色度变化。在生产可洗纺织品之前的染料选择过程中，最适合使用该程序。1.2本方法不反映某些商用洗涤产品中存在的荧光增白剂或生产过程中可能应用于纺织品的整理剂对色度变化的影响。2.原则2。1对染色织物样本进行洗涤、漂洗和干燥。在规定的温度、漂白剂浓度和时间条件下对样本进行测试，以评估多次家庭洗涤后是否会褪色。 通过仪器或视觉评估试样和原始纺织品之间的色差。

1. Purpose and Scope1.1 This test method is a diagnostic test intended to screen dyed cotton textiles sensitive to oxygen bleach detergents. It provides an accelerated procedure to assess the shade changes of dyed textiles when exposed to activated oxygen bleach detergent (simulating multiple home lauunderings, typically 10 or more). This procedure is most appropriately used during the dye selection process, prior to the production of washable textiles.1.2 This method does not reflect the contribution to shade change of optical brighteners, which are present in some commercial washing products, or finishes that may be applied to the textile during production.2. Principle2.1 A specimen of the dyed textile is laundered, rinsed, and dried. Specimens are tested under defined conditions of temperature, bleach concentration and time to assess whether fading will occur after multiple home launderings. The color difference between the test specimen and the original textile is assessed instrumentally or visually.
