发明名称 Method for the production of a brous absorption body
摘要 The present invention relates to a fibrous absorption body intended for use in disposable products such as diapers, sanitary napkins or wound dressings and also, in addition to such a novel and improved body, a method for its manufacture. The distinguishing feature of the inventive absorption body is that at least one type of absorbing fibers is included therein as well as a binder activated by heat, preferably in the form of bonding fibers; that the absorption fibers are bonded to a coherent body with the aid of the binder; and that its body, due to compression of its bulk volume, will obtain a continuous density gradient throughout said volume which is retained both in a wet and in a dry state.
