TH4864EX - Absorbent structures consisting of specific cross-linked fibers - Google Patents

Abstract

Absorbent structure with a dedicated webbing heel The only cross-linked fibers have a crosslinking substance. Between approximately 0.5 mol% to approximately 3.5 mol% calculated on the molar basis of cellulose. Anhydroglucose To react with The fibers as a crosslinked bond within the fibers, where the crosslinking agent is selected from the group containing C2-C8 dialdehyde, the functional acid dialdehyde type C2-C8. Nalythes of at least one function of aldehyde and O. The ligomers of dialdehyde and their analogues of acid dialdehyde type C2-C8 are more suitable. It is glutaraldehyde and provides a crosslink between approximately 0.75 mol% to approximately 2.5 mol%. It is also more suitable to cross within the fibers. Permeable structure has Actual dry densities are greater than wet density, consistent equilibrium balance and provide wet expansion Permeable structure Such materials may also contain hydrogel materials.
