Definitions
- this invention relates to the production of artificial nitrogenous textile fibres by dissolving casein, for example commercial casein, in a mixture formed by a borate, preferably sodium borate water and caustic soda, producing a kind of viscose that may be spun alone, or added in percentage of to 75% to other viscoses of cellulose xanthogenate, cellulose acetate or cuprammonium cellulose.
- casein for example commercial casein
- a borate preferably sodium borate water and caustic soda
- the viscose thus formed maybe coagulated even in ordinary acid baths employed for coagulating viscoses from cellulose xanthogenate or other viscoses, by using the same machines and processes as for spinning ordinary viscose.
- the fibers obtained shall contain the same nitrogen percentage as natural wool ii! they are spun from casein viscose only, or nitrogen may be fixed in the fibers in quantities from 10 to 75% with respect to nitrogen fixed in wool by spinning 1.
- Preparation of a casein base viscose (11) About 2.500 kilograms casein, (D) About 0.600 kilogram borate of sodium, (c) About 2.500 kilograms water.
- composition of viscose about 15 to 16% casein, about 1.30 to 1.60% NaOH soda, about 4% borates prevailingly in the form of sodium borate.
- Coagulating bath formed by: about 250 grams acid per litre, about 150 grams zinc sulphate per litre at the temperature of about -60 C.
- This viscose has before filtration a coagulation degree of 7 to 7%, the viscosity being -65.
- viscose is treated in vacuum for at least 10 hours in order to evacuate it, maintain ing a temperature not below about 20 C.
- the material can now be fed to the spinning machines and spun with the usual rayon spin- Ripening is carried out during 64 to '10 hours approximately at 22 to 24 C. Viscosity is thus fixed at 15-18 for 74 hours and longer. Spinning ning nozzles and coagulated with the same bath as commonly used for ordinary rayon and staple fibre.
- the temperature and, in small proportions, also the concentration of said bath should be increased as the percentage of casein in the viscose in creases.
- An artificial protein containing nitrogenous textile fibers comprising throughout its mass a 10 3.
- a process for the manufacture of artificial nitrogenous textile fibres consisting in dissolving sodium borate in water at about 55 C., slowly adding casein while stirring for about 20 minutes, adding a soda solution containing about 18% NaOH, mixing for a further 20 minutes and at the same time cooling to about 25 0., adding a cellulosic viscose previously ripened for about 54 to 56 hours and mixing until the casein solution and the cellulose are fully incorporated with each other.
