PROBLEM TO BE SOLVED: To provide a washable and repetitively usable water absorbing material without causing water leakage, a wet feeling and exudation of water and affording an excellent feeling of wearing. SOLUTION: The fabriclike water absorbing material is obtained by using a splittable type conjugated fiber composed of at least two components of a component A which is a polycapramide polymer containing ≥0.01 wt.% and ≤ 5 wt.% inert particles and the other component B that is a polyester polymer. The splittable type conjugated fiber can be split into ultrafine fibers having 0.01-3 dtex single fiber fineness. The amount of voids in the water absorbing material is ≥10 cc based on 100 cm2and the thickness thereof is 0.5-20 mm. COPYRIGHT: (C)2004,JPO
