    摘要: A process and apparatus for treating cellulosic fiber containing fabrics to improve durable press and shrinkage resistance includes using steam (36) as a vehicle to supply vaporized liquid cellulosic cross-linking agent and vaporized liquid catalyst to a reaction chamber (10) in which the fabric articles (30) are treated by cross-linking the cellulose. Normally liquid cross-linking agent (46) and liquid catalysts (52) are directly injected into a stream of treating steam to cause vaporization of the cross-linking agent and catalyst. Alternatively, a steam driven ejector type pump (42) is utilized to entrain and vaporize liquid cross-linking agent and liquid catalyst in a flowing stream of steam (32) supplied to the reaction chamber. Gaseous ammonia (52) may also be supplied to the reaction chamber to condition the cellulosic material containing fabric before cross-linking.
