Abstract
A method of finishing keratinous textile fabrics is disclosed which comprises treating the fabrics with an anionic titanium or zirconium complex at a pH in the range 1 to 4, and with a halogen containing organic acid or anhydride soluble in hot water, but preferably virtually insoluble in cold water. Such a treatment enables wool furnishing fabrics to meet the very stringent National Fire Protection Association standard 701-1969.
