Scope:

Used to compare the water absorption of non manufactured fabric materials, but not to simulate the actual usage conditions of the final product.

Testing principle:

This method tests the liquid absorption of fabrics under constant pressure. Place the sample on a specialized porous plate, where the liquid level in the storage tank is lower than the upper surface of the porous plate through a siphon. Determine the pressure absorption of the fabric by measuring the change in the mass of the storage tank over time.

Testing standards:

According to GB/T 24218.12-2012, determine the compressive water absorption of non-woven fabrics

Related terms:

Large absorption mass (Af)

The mass of liquid absorbed by the sample up to time Tf, in grams. The change in the mass of liquid absorbed by the sample from Tf to 5s before Tf is less than 1% of the mass of liquid absorbed at Tf.

Compression absorption capacity (DAC)

The ratio of the large absorption mass Af to the sample mass m, in grams per second.

Large absorption rate (MAR)

The significant change in the mass of absorbed liquid per unit time interval, measured in grams per second.
