Title: Improvements in or relating to the manufacture of artificial filaments and the like
IPC: D01F2/28
Filed: 1929-10-29
Abstract: Artificial bristles, horsehair, straw, ribbons, and like heavy filaments are produced by extrusion of solutions containing an organic derivative of cellulose and a resin either by the dry or wet spinning processes.  Bristles having a denier of 25-2000 or more may be produced.  The organic derivatives of cellulose include cellulose esters e.g. acetate, formate, propionate and butyrate and ethers e.g. ethyl, methyl and benzyl cellulose. Natural, semi-synthetic or synthetic resins may be employed, e.g. fusible and soluble synthetic resins prepared by the condensation of phenol and formaldehyde in presence of an acid catalyst, diphenylolpropaneformaldehyde resin, diphenylol propane-acetone resin, toluene sulphonamide-formaldehyde resin, benzene sulphonamide-formaldehyde resin, xylene sulphonamide-formaldehyde resin, phenol-furfural resin, the resin prepared by heating lactic acid under reflux, &c.  Natural gums and resins such as manilla, accaroid, rosin, dammar, pontianak or shellac, or semi-synthetic resin such as ester gum may be employed. The selected resin should be compatible with the cellulose derivative employed.  From 1-12 per cent of resin, based on the weight of the cellulose derivative, gives satisfactory results but more resin may be added e.g. 25-50 or 60 per cent, particularly when employing a plastifier or softener e.g. triacetin, diethyl phthalate, dibutyl phthalate, diethyl tartrate, or monomethylene sulphonamide. Suitable solvents include acetone alone or mixed with ethyl or methyl alcohol or water, and ethylene dichloride or chloroform, alone or mixed with ethyl or methyl alcohol.  In an example, a spinning solution is made up from acetone-soluble cellulose acetate having an acetyl value of 54,5 per cent as follows-acetate 33,7 parts, toluene sulphonamide-formaldehyde resin 2,1 parts, acetone 54,6 parts and water 9,6 parts; after thorough mixing and filtering, the solution is spun through cruciform jets into a drying atmosphere having a temperature of 55-87 DEG  C. and the bristles are drawn off at the rate of about 8 metres per minute.  Specifications 275,653, 317,456, 317,457, 318,630, 318,631 and 318,643, [all in Class 2 (ii), Cellulose &c.], are referred to.
