PCT No. PCT/GB92/00765 Sec. 371 Date Oct. 14, 1993 Sec. 102(e) Date Oct. 14, 1993 PCT Filed Apr. 24, 1992 PCT Pub. No. WO92/19799 PCT Pub. Date Nov. 12, 1992.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.
