Greg Turcotte and I did a test with a 90 line Chinese rug tonight. It was a one rug test only. We weighed it dry, then saturated, and performed wringing with our centrifuge and weighed it again.
Here are the results in round numbers:
A dry 90 line Chinese rug weighs in about .75 lbs per square foot.
That same rug when saturated with water increases weight to 2.25 lbs per square foot.
After the centrifuge spun the rug in less than 3 minutes, the rug weighed 1 lb per square foot.
Please consider this example:
That makes a common 10' X 12' (90 line Chinese) rug weigh in wet at 270 lbs. saturated. That is generally too heavy for one man to handle without the potential of injury and sheer physical exhaustion.
When our horizontal rug wringing centrifuge does its job, it would remove 150 lbs of water from a rug of that size. The rug would weigh in at about 120 lbs after the spin in the centrifuge. That means 30 lbs of water in the wool rug still needs to evaporate. We suggest you hang them up to dry and not lay flat on a concrete floor since that will only trap moisture and impede air flow needed for drying such a thick rug.
These are general and average numbers. Thick wool rugs will be more dramatic. Thinner pile rugs less dramatic.
Most in our industry like to talk about 90 line Chinese rugs. These are common and known to be big, fat and funky to work with, because they can hold lots of water.
