AATCC 140 Dye and Pigment Migration in the Buffer-Drying Process

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of the AATCC 140 test. This test method provides a means to evaluate the migration propensity of a pad bath system that contains dyes or pigments and may also contain different types and amounts of migration inhibitors.

When drying conditions are not constant or uniform, an uneven transition can occur, resulting in shade changes during a run, or differences in shade between the front and back of the fabric, or between the side and center of the fabric.

The dye or pigment is applied to the fabric using the impregnation drying process. This process typically involves filling the fabric with a dye or pigment solution and then drying the fabric under controlled conditions.

After the fabric is processed and dried, the extent of dye or pigment migration is evaluated. This is done by measuring the distance from the edge of the originally treated area to the point where the dye or pigment migrated.

AATCC Test Method 140 is important in the textile industry to ensure that the process of applying dye or pigment results in uniform and consistent coloring of fabrics. Excessive migration can lead to color bleeding and other quality problems in finished textile products.
