The swelling of protein fibres. Part V. The swelling of single collagen fibre bundles under load

PROTEIN STRUCTURE AND WATER ABSORPTION1

“…Osmotic swelling can be prevented by loading the fiber. If swelling has already taken place, the original length can be restored and the absorbed water can be largely, though never completely, driven out by loading the fiber (10). Under these conditions, however, even a load sufficient to break the fiber does not bring back the original width.…”
