Patent GB-560223-A (GB)
Title: Manufacture of stiffeners for footwear
IPC: D06M15/39
Filed: 1942-02-27
Abstract: Stiffeners for footwear are made by impregnating fibrous material with an aqueous solution of an aminoplast and forming the impregnated material into a stiffener in the presence of a hardening agent. Suitable resinous condensation products are those from formaldehyde and urea, thiourea, cyanamide, dicyandiamide, melamine, melam, ammeline, or 2-chloro-4 : 6-diamino-1 : 3 : 5-triazine, or mixtures thereof.  Suitable hardening agents are formic acid and ammonium chloride, sulphate, phosphate or thiocyanate.  The fibrous material may be napped or felted cotton fabric, wool or cotton felt, viscose, cellulose fibre board.  Fillers, e.g. chalk, lithopone or zinc white, dyestuffs, softening agents, e.g. aqueous solutions or emulsions of Turkey Red Oil, soap, oils, fats, and paraffin wax, and water repellants may be incorporated in the impregnating solution.  In examples (1) melamine (1 mol) and aqueous formaldehyde (3 mols) are heated at 80 DEG  C. until a test portion produces turbidity when diluted with three times its volume of water.  A cotton fabric is impregnated with the solution and dried.  The material is cut to shape, skived and moistened with an aqueous solution of formic acid or ammonium sulphate.  The stiffener becomes soft and sticky and is then applied to the last.  (2) Urea (1 mol) and formaldehyde (2 mols) are condensed until a test portion gives a precipitate with twice its volume of water.  The solution is concentrated to a solids content of 65% and is further heated at 70-80 DEG  C. and used for impregnating as in Example 1.  An aqueous solution of ammonium chloride is used as hardener.  (4) The solution of Example 2 is diluted with water and aqueous ammonium chloride solution is added.  The fibrous material is impregnated with the solution and made into a stiffener without previous drying.
