| 摘要 |
A non-woven fibrous web capable of absorbing many times its weight of aqueous liquid without losing its integrity, but which on contact with excess aqueous medium substantially disintegrates, comprises a blend of superabsorbent fibres and fibres of at least one thermoplastic polymer said web having been treated to fuse the fibres preferably in discrete zones throughout the web. The thermoplastic fibres may be bicomponent polypropylene and fused by heated calender rolls. |
