Diaper Testing
We carry out a full range of diaper testing as part of
our design and development service for new and existing manufacturers.
Our testing methods are designed to achieve a full understanding of the
relationship between the product specifications and the real performance
in panel testing.
By carrying out zoned retention tests with differing loads,
and taking into account the dimensions and fit of the diaper, we can predict
the absorption and leakage results for different sizes and weights of
babies. After all, the mechanics of leakage are not complex when the zoned
retention capacities under variable pressures are known. This prediction
can then be compared to the actual results achieved in panel tests on
real babies.
Our testing can be divided into 4 separate headings-
Absorption, Inspection, Panel tests and material tests.
Absorption
The following absorbent core tests are carried out in our laboratory:
Absorption and retention
Zoned retention under varying pressures
Speed of absorption
Rewet
Pad integrity (using patented Hardy Integrity Tester)
Inspection
A full inspection of the diaper and a 3 dimensional analysis
of the "fit". The fit is not just a factor of comfort or visual
aspect, it affects the point of application of the urine thus affecting
the spread and potential leakage of the diaper.
Test Panel Thediapers
are tested on babies of different genders and different relative "shapes"
to give as wide a range of performance as possible
The results are then correlated with the Inspection and Absorption tests
to give a complete picture of the diaper performance. Any anomalies will
be highlighted when the performance in the test panel does not match the
predicted performance.
Materials Material testing can be carried out to determine strengths, tape
adhesion, elastic tension etc, and can resolve any outstanding performance
anomalies.
Conclusions The final conclusions reached will give a clear indication of
what actions should be taken to improve your diapers to the level that
you require. We can then assist you to achieve these levels by machine
tuning, material changes, machine modification or retrofitting of new
units.
