ABSTRACT:
A process of treating textile material of a cellulosic nature with ammonia includes the step of first applying water to the textile material before the material is impregnated with ammonia. The amount of water applied must be enough to raise the moisture content of the material to a level above that normally present in the prevailing conditions of atmospheric humidity but with a maximum value of 30% by weight of the dry material.
