[scope of application]
To compare the absorption of nonwoven materials. It is applicable to the relevant inspection and inspection of nonwovens products conducted by the national labor protection equipment inspection institutions and nonwovens manufacturers.
[Related Standards]
GB / T 24218.12-2012 Test methods for nonwoven textiles- -Part 12: Determination of compression-absorbent properties.
[Principle of Instruments]
Liquid absorption of the fabric under a constant pressure. The specimen was placed on a dedicated porous plate connected to the liquid storage tank through a siphon straw that contained a liquid level lower than the upper surface of the porous plate. The compression absorptivity of the fabric was obtained by measuring the mass of the liquid storage tank over time.
