Hello, the questioner, about the nonwoven water absorption tester test principle and scope of application is as follows:
Nonwoven water absorption tester is used to test the nonwoven material under constant pressure liquid absorption, for the purpose of comparing its water absorption, but not used to simulate the actual use of the final product conditions.
Nonwoven Fabric Absorbency Tester Test Principle:
The specimen is placed on a special porous plate, which is siphoned through a siphon tube and the liquid level in the reservoir is lower than the upper surface of the porous plate, and the pressurized absorbency of the fabrics is obtained through the determination of the change of the mass of the reservoir with time.
Nonwoven Fabric Absorbency Tester Terms:
Maximum Absorbed Mass (Af):
The mass of liquid absorbed by the specimen up to the moment of Tf, in grams. Where the change in the mass of liquid absorbed by the specimen up to the time of Tf to the mass of liquid absorbed 5s before Tf is less than 1% of the mass of liquid absorbed at the time of Tf.
Depressed Absorption Capacity (DAC):
The ratio of the maximum absorbed mass Af to the specimen mass m in grams per second.
Maximum Absorption Rate (MAR):
Maximum change in mass of liquid absorbed per unit time interval, in grams per second.
The above is what I tell you about Shanghai Qianshi nonwoven water absorption performance tester related issues, thank you very much for your patience to watch, if you help, please adopt, I wish you a happy life! Thank you
