Bulk

 

Illustrated are 8 sheets of unprocessed and processed spunlace. The processed webs have 3 times the caliper of the unprocessed. Comparing two stacks of wipes of the same weight, the Micrex Processed wipes have over 15% more volume when wet (under certain process conditions).


Why bulk is important:


More volume translates to more absorbency. In fact, an equal weight of spunlace will absorb and retain over 20% more fluid. This translates to significant performance increase and / or cost savings.

Bulk is not only about absorbency.  In insulation, bulk translates to air trapping - reducing both thermal conductivity as well as noise.  Bulk also translates to increased surface area -- important in filter media.

Even at much lower levels of compaction, dramatic increases of bulk are possible.
