Definitions

  • the invention includes (1) spinning filaments from a solution of animal casein and coagulating 1 the same in acid baths (2) 2. hardening the filaments by passing the same firstly through a bath of sodium chloride at-a temperature above 25 C. and about 40 C.
  • the invention includes (1). spinning'iilaments from.,a solution of casein, coagulating the same, in acid baths, insolubilising the same 'at low temperatures and (2) treatingthe filaments insolubilised at low temperatures with solutions of formaldehyde at a temperature above 25 C. and about 70 C. to render the same boil- 'ing-proof.
  • temperature must be preferablybetween C.' and 40 C. for the first bath bf-sodium chloride or other. salts and between C; and. C. for
  • the preparatory bath for renderingthe fibers insoluble, of aluminium salts, sodium chloride or for the complete bath for rendering the fibers insoluble of formaldehyde, aluminium salts and sodium chloride or other salts It is also important that the temperature in the bath, in which. the fibers as soon as cut are introduced be not below 25 C., it being preferable to employ a temperature between the range 35 C. to 40 C. Y
  • the aluminium salts, of sodium chloride or of other soluble alkaline metal salts or earthy alka lies, to the formaldehyde solution is unnecessary.
  • This treatment could be effected with the dried casein fibers at any desired time, that is to say, even after a period of many months or years from the manufacturing date of the fiber has elapsed.
  • the treatment for rendering the fibers insoluble should be eiiected at temperatures .which. are not below 25 C., and that, when a temperature above 25 C., is applied, the relative operation should take place in an autoclave (digester) which 5 should preferably be rotary, so" as ⁇ to maintain the fibers in motion while at the same time, the
  • the invention can also be applied to the'man ufactur'e of mixed fibers of casein and cellulose.
  • the invention also covers the textile fibers of casein obtained by the indicated proc-' ess.
