Standard Moisture Regain and Moisture Content of Fibers

Moisture regain:
It is defined as the weight of water in a material expressed as a percentage of the oven-dry weight of the material. In this article, we will know the standard moisture regain and moisture content of fibers.

Standard Moisture Regain and Moisture Content of Fibers

Let,

  • Oven dry weight of a material = D
  • Weight of water in this material = W

………………………………W
Moisture regain, R = …… X 100
……………………………….D

Moisture content:
Moisture content is defined as the weight of water in a material express as a percentage of the total weight of the material.

…………………………………..W
Moisture content, C = ……….. X 100
…………………………………W+D
