Abstract

Vegetable and artificial fibrous material is impregnated with a p solution of a compound capable of condensing with formaldehyde to produce a resin, dried, and then treated with formaldehyde vapour above 100 DEG C. The condensation may be effected in the presence of a solvent for the formaldehyde which is not a solvent for the resin or for the other component, e.g. xylene. Suitable impregnating materials are phenol, urea, dicyandiamide, and butylurea. The use of a catalyst is unnecessary. In an example viscose silk is treated for 30 minutes in a bath containing 1 per cent urea at 80 DEG C., wrung out and dried, and heated in a boiler containing excess para-formaldehyde for 2 hours at 120 DEG C.
