The factor R18 is a measurement of the resistance to 18% aq. NaOH at 20‹ C. In examples: (16) a baby's napkin comprises a dried layer of a defibred pulp prepared as above surrounded by a thin coating of cellulose wadding, and above this a thin layer of non- woven fibrillated rayon fibre; (17) a compress for bandaging comprises a dried defibred pulp layer prepared as above compressed at 2 kg./ cm.<SP>2</SP> and enclosed in a thin layer of non-woven fibrillated rayon fibre; (18) a dental pad for absorbing saliva is of similar construction to the compress; (19) a sanitary towel comprises two layers of dried pulp prepared as above enclosed in a thin layer of tissue paper, the outer surface of one pulp layer being provided with a thin plastic sheet located outside the tissue paper.
