    摘要: Fibres and filaments of water-absorbent water-insoluble fibrous material have a matrix of a crosslinked copolymer formed from 50 to 95 % by weight of ethylenically unsaturated carboxylic monomer and 5 to 50 % by weight of copolymerisable ethylenically unsaturated monomer. The matrix contains dispersed solid water-insoluble particles of a material which is chemically substantially non-reactive with the matrix copolymer.
