The dynamic absorption of liquid in kitchen towel was investigated. A new method was developed. The method measures the radial spreading of the absorbed liquid using thermography. The method allows also for a controlled compression of the sample between two smooth surfaces during the absorption process. A pressure head at the inlet is avoided in order not to have an external pressure drop driving the flow. The dynamic absorption properties of kitchen towel samples comprising conventional dry creped samples with a two- and three-ply design, and a two-ply TAD sample were evaluated. The measurements were performed with the samples being compressed to different bulk levels. The absorption rate and the speed of the absorption in different directions were determined. For the conventional samples, the liquid spreading area had an oval shape, while it was approximately circular for the TAD sample. Artifacts like embossing structures had a clear effect on liquid spreading with the shape of the liquid spreading area becoming less uniform. Sample compression had a very strong influence on the dynamic absorption behavior
