Abstract

Light moulded fibrous articles are produced by mixing wood wool or like long fibres, with the inclusion of a fungicide and/or an insecticide but without any other previous chemical treatment, and Portland cement or like calcareous cement which will similarly set without the application of heat, the wood wool &c., and the cement being mixed in the ordinary way and then pressed and formed in a mould. The insecticide may comprise a solution of a copper salt such as cuprous sulphate and the fungicide may comprise a solution of ferrous or ferric chloride. A dryer such as calcium chloride may be added to induce quick setting. Specifications 258,665, [Class 70], and 374,021 are referred to.
