THE BULK DENSITY OF FIBROUS ASSEMBLIES AND THEIR BUOYANCY

摘要

The bulk density of fibrous assemblies is the key factor to affect its buoyancy and buoyancy retention. Based on wetting theory the influencing factors on the bulk density are given. For the same fibers the change of the bulk density of a fibrous assembly depends on water pressure. Compression and buoyancy experiments give some experimental results in short.
