BS EN ISO 105-E08:2014 is a technical standard that provides guidelines for testing the colorfastness of textiles. This standard specifies a method for determining the resistance of colored textiles to rubbing off and staining on other materials. It is an essential tool for manufacturers, retailers, and consumers to ensure the quality and durability of textile products.
Importance of Colorfastness Testing
Colorfastness testing plays a crucial role in the textile industry. When textiles are subjected to various conditions such as washing, perspiration, or exposure to light, there is a possibility of color bleeding or fading. This can have significant consequences, especially when textiles come into contact with other materials or are in close contact with the skin. Colorfastness testing helps identify potential issues and ensures that textiles meet the necessary requirements for color stability and durability.
Testing Procedure as per BS EN ISO 105-E08:2014
The testing procedure outlined in BS EN ISO 105-E08:2014 involves two primary methods - wet and dry rubbing. In the wet rubbing test, a piece of white cotton fabric is rubbed against the colored textile under specified conditions. Any transfer of color onto the white fabric is evaluated using a grey scale, which allows for a visual assessment of the color transfer. The dry rubbing test follows a similar process but without the use of any additional moisture.
Interpretation of Results
After conducting the colorfastness tests, the results are interpreted using the grey scale mentioned in BS EN ISO 105-E08:2014. The scale consists of a series of standardized color patches, ranging from no color transfer (Grade 5) to severe color transfer (Grade 1). The evaluation is based on visual comparison, and the obtained grade indicates the level of colorfastness. This information helps manufacturers and consumers in making informed decisions about the suitability and performance of textiles.
