The present disclosure relates to an aqueous binder composition, comprising

Aqueous binders for granular and/or fibrous substrates

This invention relates to an aqueous binder composition containing a) at least one polymer P and b) at least one saccharide compound S, such that an amount of the saccharide compound S is &#x2267;10 and &#x2266;400 parts by weight per 100 parts by weight of polymer P, wherein an amount of an additional formaldehyde-containing binder is &#x2266;50 parts by weight per 100 parts by weight of the summed overall amounts of the polymer P and the saccharide compound S. This invention also relates to a process for producing a shaped articles from granular and/or fibrous substrates where an aqueous binder composition of the present invention is applied to the granular and/or fibrous substrate, the granular and/or fibrous substrate thus treated is optionally shaped and then the granular and/or fibrous substrate thus obtained is thermally treated. This invention also relates to shaped articles obtained by a process of the present invention.

Binder for granular and/or fibrous substrates.

Aqueous binders for granular and/or fibrous substrates comprising as active constituents: a) at least one polymer which is obtainable by free-radical addition polymerization and comprises in copolymerized form &#x2267;5.5% and &#x2267;20% by weight of an &#x3b1;,&#x3b2;-ethylenically unsaturated monocarboxylic or dicarboxylic acid [polymer A], b) at least one polymer which is obtainable by free-radical addition polymerization and comprises in copolymerized form &#x2267;40% by weight of an &#x3b1;,&#x3b2;-ethylenically unsaturated monocarboxylic or dicarboxylic acid [polymer B], and c) at least one polyol compound having at least two hydroxyl groups [polyol C].

Aqueous binders granulated and/or fibrous substrates

Swellable nonwovens with reduced washoff loss are produced.

Method for producing a swelling nonwoven fabric

Aqueous binder composition for granular and/or fibrous substrates, where the binder contains i) a copolymer constructed from ethylenically unsaturated monomers; and ii) lignin.
