- Regain is defined as the weight of water in a material expressed as a percentage of the oven dry weight.
- Moisture content is the weight of water in a material expressed as percentage of the total weight.
- let oven dry weight = d
- weight of water =W
- Regain = R
- Moisture Content = M

- The properties of textile fibers are strongly affected by the atmospheric moisture content.
- Many fibers, particularly the natural fibers are hygroscopic in nature and they will absorb moisture if kept in a humid atmosphere.
- Conversely, they will tend to lose moisture in a dry atmosphere (a process known as desorption.)
- Hydrophobic fibers (e.g. Polyester) are those which do not absorb moisture if kept in a humid atmosphere.
