PROCESSO PARA A PREPARACAO DE FIBRAS SUPERABSORVENTES

摘要

The superabsorbent fibre flocks consist of a core of absorbent polymer, into which have been embedded short polymer fibres of which at least some protrude from the core. Such superabsorbent fibre flocks can be produced by bonding particles of absorbent polymer to one another and to the polymer fibres with the aid of an adhesion promoter and grinding the resulting fibre flocks to the desired particle size. The superabsorbent fibre flocks can advantageously be used in hygiene products, in particular baby napkins, sanitary towels and incontinence goods, and also for separating water and aqueous constituents from hydrophobic liquids.
