This guide covers the evaluation of the effect of dyestuff color transfer or color loss from dyed fabrics. It is designed as a laboratory screening test to aid in the formulation of detergent products or the comparison of two or more detergents, it is not suitable for detergent or washing machine rankings. The apparatus and materials use in evaluating color transfer or color loss of dyed fabrics are presented in details. The procedure for color transfer in one wash, and color loss in three washes are presented in details.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This guide covers the evaluation of the effect of dyestuff color transfer or color loss from dyed fabrics. It is designed as a laboratory screening test to aid in the formulation of detergent products or the comparison of two or more detergents.
1.2 There is no single assessment that will give the overall performance of a laundry product. A single test can only suggest how a formulation performs under the particular conditions chosen for the evaluation and cannot be expected to reflect comparative product performance under the many other possible conditions of use. A series of assessments is always necessary in order to evaluate the many aspects of product performance. It is necessary to conduct confirming tests under controlled but practical home-laundering conditions to simulate consumer experience.
