What is EN ISO 10561:2013?

EN ISO 10561:2013 is a technical standard that provides guidelines for the testing and evaluation of the colorfastness of textiles. It focuses specifically on colorfastness to rubbing, also known as crocking. This standard sets out a series of procedures and criteria to determine how resistant a textile material is to color transfer when subjected to rubbing or contact with other surfaces.

Why is Colorfastness Important?

Colorfastness is an essential attribute of textile products as it determines the degree to which colors will fade or transfer during use. Poor colorfastness can result in color bleeding, staining, and even affecting other materials or surfaces. For example, if a fabric with poor colorfastness comes into contact with skin or other fabrics, it may cause discoloration. Therefore, testing colorfastness helps manufacturers ensure the quality and durability of their textile products.

The Testing Process

The EN ISO 10561:2013 standard outlines the testing process for colorfastness to rubbing. The test involves rubbing a piece of white fabric against the surface of the textile being tested using a specified amount of pressure and for a specific number of cycles. The degree of color transfer to the white fabric is then assessed using standardized grading scales. The higher the grade, the better the colorfastness of the material.

Interpreting the Results

Based on the test results, textile manufacturers can determine the level of colorfastness of their products. A high-grade indicates excellent colorfastness, meaning that the fabric is unlikely to lose color through rubbing. On the other hand, a low-grade suggests poor colorfastness, and precautions should be taken to avoid color transfer during use. These test results help manufacturers make informed decisions about the suitability of their textiles for specific applications or customer requirements.
