AATCC/ASTM Test Method TS-018, Procedure for Absorbency

Scope: This test method is designed to measure the water absorbency of textiles by measuring the time it takes a drop of water placed on the fabric surface to be completely absorbed into the fabric.

• Sample is placed over the top of a beaker so that the center is unsupported
• A measured drop of water is placed on the fabric 1 cm from the surface
• Time is recorded until the water drop absorbs completely

AATCC Test Method 79, Absorbency of Textiles

Scope: This test measures a fabrics propensity to take up water.

• Sample is placed in an embroidery hoop with all creases out of it
• A burette dispenses a drop of water onto the surface of the fabric from a distance of 9.5mm below the burette
• Time is recorded until the water drop absorbs completely
