A water-absorbing composite, containing water-absorbing polymer particles
immobilized on a fibrous substrate wherein at least a part of said
water-absorbing polymer particles consist of primary particles having an
average particle diameter of about 50-1000 .mu.m, wherein about 30% by
weight or more of said primary particles are combined to form agglomerates
having a shape satisfying the conditions below while nearly maintaining
their primary particle shapes and a part of particles of said agglomerates
are not adhered to said fibrous substrate. This water-absorbing composite
shows excellent water-absorbing properties and a high water-absorbing
speed, and most of the highly water-absorbing polymer is stably
immobilized on the fibrous substrate and the immobility of swollen gel
after absorbing water is also excellent.
