B 30595 Abstract Paper An amino-aldehyde, eg urea-formaldehyde, resin is converted into fibres and used to form at least 1% by weight of the fibrous com- ponent of paper. The resin fibres, which are free of bound in- organic oxyacid radicals and carbohydrate, have a degree of cure of between 50 and 90%. The use of such partially cured resin fibres gives an improvement in the strength of the paper.
