AATCC 79 Test Method for Absorbency of Textiles

The AATCC 79 test, published by the American Association of Textile Chemists and Colorists (AATCC), is for determining the water absorbency of yarns, fabrics and clothing. It can be used in textiles of any fiber content or structure, including woven, knitted and non-woven.

AATCC 79 Test Method for Absorbency of Textiles

The original test method for measuring the absorbency of bleached textiles was developed to help textile dyeing and finishing mills determine the impact and efficiency of their textile preparation and processing practices.

The test method was then used as one of several metrics to evaluate the water resistance and repellency (ie non-absorbent) of textile finishing applications. After a while, the test method was also used to evaluate the resistance of textile applications to home laundering.

AATCC 79 Test Practice

Typical industrial washing procedures and techniques are followed and then physico-mechanical properties are analyzed under standard conditions. The weight of each garment increases from 5% to 36% after washing; the loop length of the fabric formed decreased from approximately 1% to 10%; For the enzyme treatment alone, CPI increased by 23% for the CVC fabric and little washing effect was observed for the other treatments.

Both longitudinal and transverse shrinkage properties of knitted garments remain the same, and the spirality almost does not change, except for 100% cotton and slub fabric. In the silicone wash, both dry and wet friction properties improved after all types of washing except 100% cotton. Increased water absorption; The pH of all samples is under control and is between 4,5 and 5,0. After these washing processes, there is no significant color fastness change in washing and staining.
