Abstract
Properties of cellulosic membranes such as the length and the ultrafiltration rate are stabilized by warmth/humidity conditioning, whereby temperatures in a range of about 30.degree. to 60.degree. C. and relative humidities in a range of about 10 to 60% are suitable. The membranes may be enveloped at a relative humidity of about 40 to 60% and at about 20.degree. to 25.degree. C. in a packaging which is at least substantially impermeable to the passage of moisture before being subjected to the conditioning.
