Title: Improvements in and relating to cellulose wadding
IPC: A61L15/20
Filed: 1953-08-31
Abstract: A process for the manufacture of cellulose wool consists in adding chlorophyll to wet cellulosic material intended for preparing the wool, fixing the chlorophyll on the cellulosic material by flocculation effected by the addition of a soluble salt of a polyvalent metal to the aqueous bath and then completing the preparation of the cellulose wool.  In order to fix the chlorophyll a soluble salt of a polyvalent metal e.g. aluminium sulphate, alum or soluble salts of barium is used.  The fixing may be improved by the addition of an amylaceous material.  In an example, bleached sulphite pulp, soft pine, cold wood pulp and broke are crushed and triturated in water.  Chlorophyll and an amylaceous product are then added and after mixing, aluminium sulphate is added.  The mixture is then passed to a cellulose wool machine to complete the production of the cellulose wool.  The wool may be used for sanitary towels, wound dressings, babies' napkins, dress shields or insoles of shoes.
