GB-T 3922 Textile - Color Fastness Tests - Standard Test Method for Color Fastness to Perspiration

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of GB-T 3922 test. Color fastness to perspiration refers to the ability of a dyed fabric not to fade or stain due to sweat. Clothing that comes into contact with the person with heavy sweating can cause severe discoloration. Color fastness to sweat tests are performed to determine the resistance of dyed textile color to acidic and alkaline perspiration effects.

This test is especially applied for sportswear and heavy-duty clothing. Normal fabrics are also tested for color fastness to sweat in order to determine the color quality.

The International Standards Organization (ISO) has determined a method with the ISO 105-E04 standard to be used in the evaluation of the resistance of dyed, printed or otherwise colored textile yarns and all kinds of fabrics against the effects of human perspiration.

Grayscale is used to control the color change in the test sample. This scale consists of nine parts from 5 to 1. In this beard, each color difference is given a rating. Ratings are made between 5 and 1 to control the dyeing change from adjacent fabric.
