Predict comfort degree
For filling materials such as staple fiber and bulky filament yarns, the Bulk Tester BT 100 gives feedback about comfort properties such as filling power and recovery properties of pillows and similar end products.

Reproducible test results
The measurement procedure involves compression respectively decompression of a bulky fiber or filament sample for a pre-set number of cycles. Objectivity and reproducibility of measurement results is guaranteed by the automatic movement of the compressing weight.

Test method
A loading weight automatically compresses respectively decompresses the sample for a pre-set number of loading cycles. An analysis of the sample height in compressed respectively decompressed condition determines the elastic recovery of the material.
