Description

Patented June 11, 1935 2,004,271 PRODUCTION OF ARTIFICIAL FILAMENTS, THREADS, RIBBONS, FILMS, AND THE LIKE Henry Dreyfus, London, England N 0 Drawing. Application October 28, 1930, Serial No. 491,816. In Great Britain November .5, 1929 10 Claims. This invention relates to the manufacture f filaments, threads, ribbons, films, sheets or other products from viscose.
In prior U. S. Patent are described for the manufacture of filaments for example ammonium, sodium or calcium thiocyanate.
I have now found that such coagulating agents are advantageousin the case of the formation of filaments or other products of regenerated cellulose.
As in U. S. Patent No. 1,465,994 the process permits of the production of filaments or other cross-section of the products being produced. ning With relatively large jet orifices higher concentrations of thiocyanate may be employed than with smaller jet orifices. At the same time the use of relatively. concentrated solutions of thiocyanates enables the products to be drawn out to fine deniers or low cross-sections.
Any desired additions may be made to the coagulating liquids for the purpose of assisting or increasing the regeneration of the cellulose.
wetting agents.
As indicated above a stretch may be applied to the materials during coagulation so as to draw them out to the required denier or cross-section.
Alternatively or in addition a stretch may be applied thereto after coagulation and during or after regeneration of the cellulose (where a subsequent treatment is applied for this purpose); for instance filaments may be carried in succession round two or more feed rollers having successively increasing peripheral speeds.
The following example shows the best method For example, in spinknown to me for carrying the invention into effect, but it is not to be regarded as limiting it in any Way:-
Example relatively short time, for example 18 30 hours, and in which the viscose has been allowed to stand for about 70-80 hours at 17 (3., is spun through a nozzle having spinning apertures of 0.08 millimetre diameter into an aqueous coagulating bath containing 6-8% of concentrated sulphuric acid, 20-30% of sodium thiocyanate, 1% of zinc sulphate, and 10% of glucose, the bath being maintained at a temperature of about 10 C., and the length of immersion of the filaments being 16-20 inches. The yarn is carried out of the coagulating bath and wound on a bobbin the rate of extrusion of the spinning solution from the nozzle. The yarn may be further Washed and dried as desired.
What I claim and desire to secure by Letters I Patent is:
1. Process for the manufacture of filaments, threads, ribbons, films or other products from viscose, comprising spinning viscose into an aqueous, coagulating bath containing a thiccyanate.
2. Process according to claim 1, thiocyanate used is that of sodium.
3. Process for the manufacture of filaments,
wherein the thiocyanate in a concentration of 20 to 30%.
5. Process for the manufacture of filaments,
which either a. or b may be zero.
6. Process for the manufacture of filaments, threads, ribbons, films or other products from viscose, comprising spinning viscose into an aqueous coagulating bath containing a thiocyanate and a compound selected. from the group consisting of glycerine and sugars.
'7. Process for the manufacture of filaments threads, ribbons, films or other products from viscose, comprising spinning viscose into an aqueous coagulating bath containing a thiccyanate and a wetting agent.
8. Process for the manufacture of filaments, threads, ribbons, films or other products from. viscose, comprising spinning Viscose into an aqueous coagulating bath containing a thiocyanate, and subjecting the product to a stretching operation. 7
9. Process for the manufacture of filaments, threads, ribbons, films or other products from viscose, which comprises spinning viscose into an aqueous coagulating bath containing a thiocyanate and then treating the formed materials to regenerate the cellulose.
10. Process for the manufacture of filaments, threads, ribbons, films or other products from viscose, which comprises spinning viscose intoan aqueous coagulating bath containing a 'thiocyanate, subjecting the product to a stretching operation and then treating the formed materials to regenerate the cellulose.
