10—Freezing Point Depression in Assemblages of Moist Fibres

Abstract

Examination of the moisture in fibres by the rate-of-cooling method shows evidence of freezing only when the moisture is above a limiting value with any fibres. The limiting value has been correlated (i) with the chemical composition of the fibres, e.g., the degree of substitution of cellulose acetate, (ii) with the physical characteristics, e.g., with the crystallinity and (iii) with other properties, e.g., absorption of water vapour.
