Abstract
In this paper the relations between the volumes of dry fibres and fibres with different percentages of regain are discussed. With the aid of these relations and based on the opinion, that a solid substance will not sorb a liquid with appreciable contraction, the conclusion is reached that water will be sorbed by hydrophylic fibres in three ways, viz.: by absorption in the outer layer of the micelles, by adsorption at the micelle surface without contraction, and by capillary condensation also without contraction. The effect of the felting process and dyeing processes on the quantity of water sorbed, and more generally on the sorptive capacities of the fibres cotton, silk and wool is discussed.
