PROCESS FOR MANUFACTURING TUBULAR PRODUCTS OF CELLULOSE OR COMPOUNDS OF CELLULOSE.
Specification of Letters Patent.
Application filed June 21, 1916, Serial No. 105,058. Renewed February 5, 1920. Serial No. 356,419.
To all whom it may concern:
Be it known that I, LEOPOLD HESSE, a
subject of the German Empire, residing at Oberbruch, near the cityof invented a certain new and useful Process for Manufacturing Tubular Products of Cellulose or Compounds of Cellulose; and I do hereby declare the following to be a full,
clear, and exact description of my invention.
My invention relates to a process of manuess. The product shows the optical effect of layers of thin transparent lamellas pressed together. This effectvaries with the thickness and form of the ribbons, the relative position of them, and the tension in the spirals. I
The thickness of the ribbons depends upon the width of the slits, theconstitution of the cellulose-solution and the stretching during the spinning process, the latter and the properties of the precipitating bath being essential for the tension in the dry material. .The slits may be of any suitable form, they 'may be straight, curved or indented. The ribbons may also be twisted several together.
For spinning I use a so-called spinning pot or a spinning centrifuge. By varying the sort of solution of cellulose, by using slits of different width and shape, by changing the quality of the precipitating bath and the manner of spinning, influencing the shrinkage and tension in the finished fabric, I can produce fabrics of different appearance, which are to be used as substitutes for straw, hemp, tagal-fiber, etc., having the advantage of being endless.
Aachen, Kingdom of Prussia, Empire of Germany, have Patented June 1, i920.
' The process resembles the method for producing jute, in which paper, out to strips, is rolled up in spirals and twisted to tubular products. The paper strips may also be replaced by finished strips of cellulose films WhlOll may be rolled up in endless spirals. but the obtainable fabrics are far inferior to the products which I obtain by my wet spinning process in a more economical way.
For finishing the fabrics I treat them in the same way as the fabrics of artificial silk, by washing out the precipitating chemicals and drying under tension.
The feature of my invenion is the produc-.
tion of fabrics of great softness, with separated heat isolating spaces in the interior of the product.
An apparatus which may be used in producing the tubular threads is illustrated in the accompanying drawing, wherein Figure 1 1s a somewhat diagrammatic view of-the apparatus, and Fig. 2 is a View of the spinning nozzle and showing the character of the projected and spirally twisted filament.
Insaid drawings, A designates a spinning nozzle having a long narrow slit a therein from which the cellulose solution is projected in a broad thin strip or ribbon and precipitated in the bath B.- Preferably the precipitated strip of cellulose, while still plastic, is led over a roll 0 to a rotating spinning pot (1 having feed rolls 0, the cellulose strip being wound into hollow spiral form between the roll a and rolls 0', and coiled 1n the bottom of the pot A rack and gear 0 turns the feed rolls 0.
\Vhat I claim is:
A process for manufacturing tubular cords of cellulose or cellulose-compounds, consisting in ejecting solutions of cellulose or cellulose compounds through elongated spinning slits into precipitating baths and rolling up the resulting ribbons or strips into endless spirals by spinning or twisting, substantially as set forth.
In testimony that I claim the foregoing as my invention, 1 have signed my name in presence of two subscribing witnesses.
