Testing Wet Tensile Strength of Absorbent Paper
On the way of innovation, Tinius Olsen
now uses its Tensile Testing Machine to put up a test to measure the
wet tensile strength and performance of tissue and absorbent paper. Wet
tensile strength is the maximum force supported by the unit width of a
wet test piece of tissue/absorbent paper until the onset of rupture
using a tensile test. EN 12625 defines the preparation of the test specimen in terms of the edge quality and dimensional tolerances. The test specimen is placed into a Tinius Olsen tensile testing machine upper
clamp so that a loop is produced around what is called the “Finch”
soaking device bar; the soaking vessel containing water is raised
allowing soaking for 15 seconds, the tensile force is then applied & once the specimen ruptures, the
soaking vessel is removed. Results are automatically reported through Horizon
test software in terms of Mean wet tensile strength (N/m) & Relative wet tensile
strength (%) which qualifies the strength & performance of the
tissue/absorbent paper.
