Abstract
For maximum liquid-holding capacity, an uncompressed fibrous assembly requires wettable fibers of high wet modulus. Tests with rayons of various denier, state of finishing, and modulus indicate that, for compressed absorbents, it also is desirable to minimize the required compaction forces by reducing the dry modulus and resilience of the fibers. The use of wet crosslinked rayon, which has the requisite combination of wet and dry properties, leads to significant improve ments in absorbency. The effect of increasing bulk density on the liquid capacity per unit weight and capacity per unit volume of absorbents is discussed, and a mechanistic description of the latter is presented.
