Abstract
The present invention relates to an aqueous binding composition containing a) a reducing sugar; b) ammonium sulphamate and/or sulphamate of an alkaline or alkaline-earth metal; c) a pH- adjusting agent selected from ammonium hydroxide (NH4OH), an organic and/or inorganic ammonium salt and/or an organic amine; and a resin (or pre-condensate) obtained by reaction of a polyaldehyde, a urea compound and at a lignin sulphonate and/or a condensation derivate thereof with a polyaldehyde, the resin being present in a percentage of at least 10% by weight on the dry weight of the composition. The binder may be efficiently used to bind cotton fibres, cellulose fibres, organic tissues, coal dust, natural and artificial inorganic fibres, thereby obtaining products with good mechanical properties.
