Definitions
- the quantity ratio fiber / binder (solid / solid) is set to 2.5: 1 for the determination of the nonwoven fabric hydrophilicity.
- the distance between the funnel and the nonwoven is 2.5 cm.
- the viscose nonwoven fabric obtained had a fiber / polymer (solid) weight ratio of 2.5: 1. Seven times the nonwoven weight of superabsorbent particles was firmly fixed on the nonwoven, ie almost no particles trickled down from the nonwoven surface.
- the superabsorbent nonwoven had a thickness of approximately 0.8 mm. Its water absorption capacity was determined by placing the nonwoven fabric in a 0.9% saline solution for 10 minutes, then hanging it up for 10 minutes to dry and then weighing it. The water absorption capacity of the material results from the difference in weight before and after immersion in the aqueous saline solution. In the present example it was 1,500%.
