Step 1:weigh the cotton (before absorbing the moisture). Step 2: Now weigh the cotton (after absorbing moisture) Step 3: Subtracting results of Step 1 from Step 2. This will be the measurement of moisture. Raza Hasnain
Modal fibers have a moisture regain of approximately 12-13%. This means that modal can absorb and retain moisture effectively, making it comfortable to wear in various climates. The fiber's ability to maintain moisture also contributes to its softness and breathability, which enhances overall comfort.

(This fiber refers to Textile fiber)Natural fiber are naturally growing from Cotton plant.Man made fiber are polyster,rayon,viscose staple fiber. Its is a process of wood pulp chemically treated and processed to make a fiber equal to natural fiber with same qualities.viscose and cotton virtually have nodifference.But polyster have poor qualites compared to other in areas like thermal regain,moisture regain,softness,anti pilling,air premeabilty.
Cotton wool shrinks in water for two main reasons. 1. Cotton (and wool, silk, etc.) swell up when they come in contact with water because they absorb water. They subsequently shrink when the water is removed from them. This is called water regain. Cotton has the fifth highest water regain (with wool having the most). 2. When agitated, such as when hand/machine washed (much more apparent in machine washing), the cotton fibres are forced together, packing more closely, which gives the overall effect of shrinking the cotton.
