Definitions
- This invention concerns improvements in or relating to processes for the manufacture of artificial textile fibers.
- casein fibers refers to fibers made from casein solution alone or of a mixture thereof with cellulosic vis- 35 cose.
- casein is hardened by formaldehyde but the coagulated fibers contain a condehyde could have rendered them insoluble.
- the coas ated fibers are hardened in an aqueous solution orwmcn formaldehyde forms the basic substance together with the addih v which prevents further swelling of the fibers.
- the fibers may be treated'with solutions, of
- aluminium salts are ,potassium alum, aluminium chloride and aluminium sulphate. It is preferable, however, and even very important, to operate with various solutions having progressively increasing concentrations, and to begin the treatment of the filaments with weak concentrations, for instance with 99 parts of 12% aqueous solution of sodium chloride and 1 part of 40% formaldehyde, gradually passing to higher concentrations.
- the procedure is the same when aluminium salts are ,added, but it is preferable not to reduce thesodium chloride concentration below 10% in order to avoid an excessive and undesirable swelling of the fibers.
- the solution for rendering the filaments insoluble which are prepared in the manner de- 0 scribed above may be slightly acidified, preferably with sulphuric acid.
- the fibers are rendered partially insoluble and are maintained under tension in an initial lowconcentration bath, in order e to prevent shrinkage thereof, and subjected to further treatment 'in baths of higher concentra-" tion after being cut to a desired length in order 40 to obtain. a twisting thereof.
- the fibers may also be. rendered insoluble by treatment in an initial low.,concentration bath and by subsequent treatment in a series of baths of gradually increasing concentration.
- a salt such as sodium chloride
- the after-stage of rendering such filaments into permanent fibers characterized by the following steps: promptly treating the weak water-containing filaments from the coagulating bath in an aqueous bath containing both formaldehyde for insolubilizing functions and sodium chloride to prevent undue swelling before insolubilizing is completed; and comprising about 90 parts of a sodium chloride solution of about to 12 percent strength and about 10 parts of' a formaldehyde solution of about 40 percent concentration.
- thestage, following theresulting acid coagulation comprising the step of treating the coagulated filaments in at least one aqueous bath in which sodium chloride has been dissolved, and thereafter in aseparate-bath rendering the filaments insoluble with formaldehyde.
- A-process'as per claim 4' in which at least one salt chosen fromthe group consisting of the soluble salts ofaluminum, is added to at least one of said sodium chloride baths.
