- a temperature above 28 C. may be employed in those baths or at least in the bath or one or more of the baths (1)) containing formaldehyde, as in the process forming the subject matter of the aforesaid U. S. patent applications No. 330,725, 348,992, both now abandoned and U. S. Patent No. 2,338,917, for example, if a temperature not above 25 C.
- a temperature above 25 C. preferably a temperature of 70-75 C.
- the fibre obtained will be much softer and larger after acid boiling than a urea-free fibre and from. this point of view, can be compared with a fibre treated with a chromium salt, but with the advantage, however, that the fibre retain a perfectly white appearance.
- casein filaments alreadycoagulated but not yet insolubilized by formaldehyde cannot be treated with a simple solution of urea, as a simple solution of urea dissolves casein and in consequence the filament would at once dissolve in the solution.
- a simple solution of urea dissolves casein and in consequence the filament would at once dissolve in the solution.
- a saline solution of urea preferably concentrated and astringent
- no dissolving of the filament occurs, but only a slight swelling of the filament, which can be adjusted at will by varyin the degree of concentration and/or the astringent capacity of the solution according to the amount of urea that has to be absorbed by the filament and to the degree of penetration of the urea that has to be obtained.
- Urea may in some cases be present in the formaldehyde-free acid salt coagulating bath, but in general, coagulation of the filament is hindered and there tends to be a large loss of urea in the first de-acidifying bath following the coagulating bath.
- An aqueous saline bath having the composition of the bath (1)) but containing in addition gms. of urea crystals per litre of the bath and more sodium chloride until the bath is saturated.
- the fibres are now out to the required length after which they are treated, preferably in an autoclave, in an aqueous bath (e) containing gms. of aluminium sulphate, 200 gms. of sodium chloride and 40 gms. of 100% formaldehyde per litre, for 5-6 hours.
- aqueous bath e
- aluminium sulphate 200 gms. of sodium chloride
- 40 gms. of 100% formaldehyde per litre for 5-6 hours.
- the insolubilized fibres are now washed and treated in an aqueous bath or baths (1) of soluble phosphates, for instance such a bath containing 4 gms. of monosodium phosphate per litre, after which the fibres are washed again and dried.
- the preferred temperature for the various baths are: 35 l0 C. for bath (a) 50-55 C. for bath (b):
- Example II The procedure in this example is the same as in Example I, except that the filaments are out after bath (0) instead of after bath ((1), the out fibres being gathered together in a vessel containing bath ((1), in which they are treated for 3-4 hours at 35-40 C., then treated in bath (e) at 70-75 C. for 5-7 hours, then washed, then treated in the bath or baths (1) and finally, washed again and dried.
- Example III The procedure in this example is the same again as in Example I, except that the filaments are out after the bath (b) instead of after bath (d), the cut filaments being gathered together in a vessel containing bath (0) in which they are treated for 2-3 hours at 35-40 C., and then, after having been squeezed out, in conformity with Example II, omitting bath (e).
- urea as employed herein includes all soluble salts containing urea such for example as thio-urea.
- the invention includes both the use of milkcasein and also the use of vegetable casein for example soya bean casein, either being used alone or the two in admixture with one another.
- aqueous urea bath is rendered saline by the addition of sodium chloride and aluminum sulphate in the proportions, per liter, of about grams of urea crystals, about grams initially of sodium chloride, and about200 grams of aluminum sulphate; the sodium chloride content bein then increased unti]. substantial saturation is reached.
