US patent specification by James Monach of Philadelphia, assignor to himself, Jeffery Hart and Robert Thorp of Conshohocken, Pennsylvania, for treating jute fibre so it can substitute for or be mixed with wool. The process boils jute for about two hours in caustic alkali of roughly 60° Twaddell, then washes it, neutralizes it in weak sulphuric acid, washes and dries it. The treated fibre can be carded, bleached, dyed and spun like wool. The claim is for jute fibres treated with caustic alkali of that strength.
