If you are, or want to be,  involved in any facet of the manufacture or sale of baby diapers, sanitary napkins, adult incontinence or similar absorbent products, please read through our pages and contact our Consultant, Philip Hardy, by phone,  fax or  e-mail. 

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
The diapers 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.
