发明名称 ABSORBENT STRUCTURE AND PRODUCT BASED ON RAW MATERIALS HAVING A HIGH DEGREE OF RENEWABILITY
摘要 The invention relates to an absorbent structure and an absorbent product, such as a nappy, an incontinence shield, a sanitary towel or the like, which product includes the absorbent structure. The absorbent structure includes a superabsorbent which has been produced from one or more hydrophilic monomers by free radical copolymerization in the presence of starch and/or chemically modified starch. During production of the superabsorbent, use has been made of a free radical initiator which forms three or more radical sites per molecule. The absorbent structure furthermore includes hydrophilic and/or hydrophobic fibres which, together with the superabsorbent, impart a hydrophilic character to the absorbent structure. In the dry state, the superabsorbent constitutes between 10 and 75 % of the dry weight of the absorbent structure. The absorbent structure and the product are based on raw materials having a high degree of renewability.
