What is EN ISO 105-K07:2017?

EN ISO 105-K07:2017 is an international standard that provides guidelines and procedures for the assessment of color fastness to rubbing. It specifically focuses on determining the resistance of colored textiles to dry or wet rubbing.

Importance of Color Fastness

Color fastness is a key characteristic in determining the quality and durability of textiles. It refers to the ability of a material or fabric to retain its color when subjected to various external factors such as rubbing, washing, light exposure, and perspiration. The evaluation of color fastness is crucial as it ensures long-lasting vibrant colors, prevents color bleeding, and helps maintain the overall aesthetics of textile products.

Testing Methods and Parameters

The EN ISO 105-K07:2017 standard outlines specific test methods and parameters to evaluate color fastness to rubbing. These methods involve the use of specified equipment, such as a crockmeter or rubbing tester, along with standardization of parameters like load, number of rubs, and the type of fabric substrate used. The test evaluates color transfer from the specimen to a standard white fabric or vice versa and is carried out in both dry and wet conditions.

During the testing process, the color changes or staining are visually compared against standardized grey scales, which provide a consistent reference for assessing the degree of color transfer. Results are rated on a scale ranging from 1 to 5, with 5 indicating no color transfer. The standard further provides guidance on the interpretation of test results and the classification of color fastness levels.

Applications and Benefits

EN ISO 105-K07:2017 is widely used in laboratories, textile industries, and regulatory bodies to determine the color fastness of various textile products ranging from clothing and upholstery to carpets and technical textiles. Compliance with this standard ensures that the color integrity of textile products is maintained, thereby enhancing customer satisfaction and product longevity.

Additionally, manufacturers can use the results obtained from these tests to improve their production processes and select appropriate dye materials or finishes to enhance color fastness properties. By adhering to this standard, they can optimize the quality, performance, and value of their textile products.

In summary, EN ISO 105-K07:2017 plays a vital role in assessing color fastness to rubbing for textiles. It provides standardized procedures, equipment, and parameters for conducting tests and ensures consistent evaluation and comparison of test results. Adhering to this standard enables textile producers to offer high-quality, long-lasting, and visually appealing products to consumers across the globe.
