Abstract

Artificial threads are produced from protein by extruding a solution of a protein into a setting medium, subjecting the freshly-extruded thread to a hardening treatment to render it resistant to cold water and stabilizing the hardened thread against the action of hot water and hot dilute acid by treating it with an aqueous solution containing an ionogenic compound giving rise to cyanic ions in such a manner that the treated thread contains or carries substantially no free chemically uncombined cyanate and then drying the thread at an elevated temperature, preferably between 50 DEG and 90 DEG C. In an example stretched lactic casein threads are hardened for 3 hours in an aqueous bath at 55 DEG C. containing in each litre 380 grams of sodium sulphate, 10 grams of formaldehyde and 40 grams of sulphuric acid. The threads are then washed in water and immersed for 20 minutes in an aqueous bath containing, in each litre, 20 grams of sodium cyanate and 1 gram of a cation-active soap as a finishing agent. The threads are then centrifuged to about 100 per cent. liquor retention and dried for 3 hours in a humid atmosphere at 70 DEG C. The cyanate bath may contain about 5 grams per litre of cadmium chloride as a bactericide. In other similar examples the hardening bath also contains aluminium sulphate and two successive hardening baths are used prior to the treatment with sodium cyanate. In another example lactic casein thread is esterified with methyl alcohol in the presence of sulphuric acid between two hardening treatments (as described in Specification 690,492) before treatment with sodium cyanate. The number of processing steps of the present invention following the hardening treatment is less than that of the similar protein thread treatment disclosed in the parent Specification. Specification 653,188, [Group IV(b)] also is referred to.
