BICOMPONENT SUPERABSORBENT FIBRE

摘要

The present invention concerns a multicomponent superabsorbent fibre which comprises a first superabsorbent material and a second superabsorbent material. In at least a part of the length direction (L) of the superabsorbent fibre, the first superabsorbent material and the second superabsorbent material are located side-by-side in the cross-direction (C) of the superabsorbent fibre. The first and second superabsorbent materials are selected such that - at a given point during their swelling - the swelling capacity (SC) of the first superabsorbent material is greater than the swelling capacity of the second superabsorbent material so that the superabsorbent fibre (10) curls upon contact with liquid. The invention also concerns a method for reducing gel-blocking in a superabsorbent fibre.
