Title: Improvements in or relating to fibrous materials treated with disinfectant
IPC: A61L15/18
Filed: 1932-10-12
Abstract: Germicidal properties are imparted to fibrous materials particularly in manufactured sheet form, e.g. paper, woven fabrics, &c., but excluding artificial silk or similar products, by coating or impregnating them with a liquid incorporating one or more cadmium salts, together with a binding-agent, e.g. glycerine, starch, gum, hygroscopic salts such as calcium chloride &c.  The binding agent should be chemically neutral but may interact with the cadmium compound, and should adhere well to the fibrous materials.  The germicidal solution may be used as a spray, as a bath &c., or added to paper pulp.  In an example 12 lbs of a solution comprising 3 per cent cadmium sulphate and 1\ba1/2\be per cent glycerine, in water is applied per 100 lbs of paper by rubber rollers to glossy transparent paper, and to cr<\>zepe paper.  In further examples, towels, mattress tick, and sanitary towels are treated with a solution of 2 per cent cadmium sulphate and 1 per cent glycerine, bacterial tests being described.
