Spinning soya protein fibre

Considerable research was undertaken into methods of improving the quality of the protein curd. Denatured soya bean protein tends to aggregate rather than crystallise so many of the modifications were intended to overcome this adhesive-like behaviour which gave rise to a variety of technical problems. US Patent 2,112,210 describes a process in which the protein was solubilised in sodium hydroxide, treated with carbon disulphide and oxidised with air. It was hoped that this method would result in a fibre with better spinning viscosity, stability and tensile strength.
