AATCC 193 Absorbent capacity of fabrics by gravimetric method
The AATCC Test Method 193, titled "Absorbent Capacity of Fabrics by Gravimetric Method," provides a standardized approach to measuring the absorbency of textiles. This test is particularly valuable for assessing how effectively different types of fabrics can absorb moisture or other liquids, which is crucial in various sectors such as healthcare, automotive, and home furnishings.
The gravimetric method involves submerging a known weight fabric specimen into a predetermined volume of distilled water at room temperature. After the specimen reaches equilibrium with the liquid, it is removed, dried under specified conditions, and weighed again to determine the mass of absorbed fluid. This process allows for accurate quantification of absorbency.
Specimen preparation plays a critical role in this test. The fabric must be cut into standard-size pieces that are representative of typical usage scenarios. Factors such as the size of the specimen, its shape, and the method used to secure it during testing can influence results. Proper handling ensures consistency across tests.
Instrumentation for this method includes a balance capable of precise weighing down to milligram levels, a drying oven with controlled humidity and temperature settings, and a container large enough to submerge the specimens without any fabric overlapping. The distilled water used should be deionized or reverse osmosis purified to avoid introducing impurities into the test.
Acceptance criteria for this method are based on the absorbent capacity values obtained from the gravimetric analysis. These values are typically expressed as milligrams of absorbed fluid per square centimeter (mg/cm²). The standard specifies allowable variations in these values depending on fabric type and end-use application.
Real-world applications of this test include ensuring that medical gowns or bandages can effectively manage patient fluids, validating the performance of seat cushions in vehicles to prevent moisture accumulation, and confirming the water resistance properties of outdoor clothing fabrics. Accurate absorbency testing helps manufacturers meet regulatory requirements and improve product quality.
