The relative amounts of kemp to wool vary from breed to breed and make some fleeces more desirable for spinning, felting, or carding into batts for quilts or other insulating products, including the famous tweed cloth of Scotland. Wool fibers readily absorb moisture, but are not hollow. Wool can absorb almost one-third of its own weight in ...
Breathability: In general, wool's comfort comes from its thermo-balance characteristics. The breathability factor of a material depends on its ability to absorb moisture relative to its weight and then release it into the air. The higher the absorption value the better the textile is at adapting to humidity level changes.
Other polymers, such as polyethylene and polystyrene, do not normally absorb much moisture, but are able to carry significant moisture on their surface when exposed to liquid water. [ 33 ] Type-6 nylon (a polyamide ) can absorb up to 9.5% of its weight in moisture.
Rockwool's product, for one, is also moisture resistant. If the product gets wet due to flooding in the house or a leak in the roof, it can be dried out and it is very resistant to mold and mildew.
The moisture content of grains is an essential property in food storage. The moisture content that is safe for long-term storage is 12% for corn, sorghum, rice and wheat and 11% for soybean [1] At a constant relative humidity of air, the EMC will drop by about 0.5% for every increase of 10 °C air temperature.

Wool is a highly effective insulating material which performs better than its rated R value because it can absorb and release moisture. [3] Mongolian nomads used [when?] felted and woven sheep wool pads as an insulating layer on the walls and floors of their dwellings, called ger or yurts. The use of wool for insulation is starting to rise in ...
Consuming foods stripped of fiber — such as processed and ultraprocessed foods like fast food and snacks — may keep fiber intake too low to move bulk through the system adequately.
An increase in a w is usually accompanied by an increase in water content, but in a non-linear fashion. This relationship between water activity and moisture content at a given temperature is called the moisture sorption isotherm. These curves are determined experimentally and constitute the fingerprint of a food system. [2]
