Pool Water Fastness

Some chemicals are used to keep the pool water clean and not to harm human health. Although these substances are beneficial for human health, they may be damaging to textile products. The fastness of the pool water is done to determine the damages that the chemicals present in the pool water, especially swimsuits and similar garments, can cause damage to the color of the fabrics.

Pool water fastness tests are performed by authorized laboratories in accordance with the criteria and standards published by national and international institutions. These laboratories are accredited by national or international accreditation bodies in accordance with the standards of TS EN ISO / IEC 17025 General Conditions for the Competence of Testing and Calibration Laboratories.

In order to evaluate the results of the fastness tests, the gray scale used in the fading assessment is used to determine the color change (TS 423-2 EN 20105-A02 Textile - Methods for color fastness determination - Section A02 - Use of gray scale for the evaluation of fading).

The fastness of the pool water, which is made with the aim of determining the durability of the colors of the printed or dyed textile products to be used in the pool water, is determined in accordance with the following standard:

  • TS EN ISO 105-E03 Textiles - Color fastness tests - Part E03: Color fastness to chlorinated water (swimming pool water)

The value of the dyestuffs used in the textile sector is measured by the fastness value of the dyed fabrics during the other processes in the factory or during the use of the product. In other words, color fastnesses of dyes are considered as fabrication fastnesses and usage fastnesses. The fastness value of the pool water is related to the fastness to use. Use fastnesses include light fastness, wash fastness, dry cleaning fastness, sweat fastness, fastness to sea water.
