Color Fastness to Vapor

A number of processes are applied to change the qualities of all kinds of textile materials, such as fibers, yarns, fabrics or clothing, depending on their application and consumer demands. These processes are called finishing processes. Finishing processes are divided into three groups: pretreatment, printing and dyeing, coloring and finishing processes.

With pre-finishing processes, textile materials are made ready for dyeing or printing. A number of undesirable substances are removed from the textile surfaces. At this stage, processes such as bleaching, mercerization loosening or causticisation are applied. Coloring is done by printing or dyeing methods. Coloring is the treatment of dyes with textile products. This process ensures the permanence of the applied printing and colors at the same time. Finishing processes are carried out with the aim of giving textile products a better appearance, attitude and usage properties. At this stage, a number of mechanical methods or chemicals are applied to the fabrics. Now textile products are completed to be presented to the consumer.

As can be seen in all these stages, the fabric is given a number of features. Color fastness to steam of textile products is one of these properties. These fastness tests determine whether the fabric is discolored or contaminates adjacent materials during high vapor exposure.

The color fastness tests against steam carried out by accredited laboratories are in compliance with the following standards:

  • TS 7189 EN ISO 105-E11 Textiles - Color fastness tests - Part E11: Color fastness to steam

During the tests to be carried out in accordance with this standard, all kinds of textile products, whatever their shape and shape, are rolled into a cylinder and placed on the mouth side of a container containing boiling water. This standard seeks to determine the extent to which printed or dyed textile products dye adjacent fabrics.
