J'ULES ROUSSET, OF NOGENT-SUR-MARNE, FRANCE.
ARTIFICIAL TEXTILE FILAMENT AND PROCESS OF MAKING SJE.
Application filed November 15, 1921.
T 0 all whom it m by can earn Be it known that I, JULl-IS Roussnr, citizen of the Republic of France. and resident of Nogent-sur-lvlarne, Seine, France (postofiice address 20 Rue des .Dtenscurs de Verdun), have invented a new and useful Artificial Textile Filament and Process of Making Same, which improvements are fully set forth in the following specification.
Hollow artificial textile fibers have been heretofore obtained by various means either by spinning or drawing a solution adapted to yield artificial textile fibers, for instance suitably matured viscose, forming an emulsion with air or some other suitable fiuid, or by spinning or drawing a viscose, in which has been embodied a body calculated to emit under chemical action gaseous bubbles within the fiber after the latters issue from the spinning machine or draw-plate; or by spinning or drawing viscose, in which has been dissolved air or any other gas that has been kept dissolved until after or immediately before issue from the spinning machine or draw-plate. Under the foregoing conditions threads or blades are obtained in which gas bubbles remain imprisoned after manufacture; the said bubbles being either separate or connected with one another and, in the latter case, the threads are transformed into real tubes filled with what gas has been used or reaction-developed.
The object of my invention is to provide a novel hollow textile fiber, continuous, discontinuous, or in flocks, endowed with all the properties of the gas-imprisoning hollow textile fiber but afi ording besides. most valuable qualities of suppleness and elasticitv.
This artificial textile fiber according to my invention is manufactured like the'aforementioned fiber either by means ofa suitable matured viscose emulsion. or by means of any other spinnable or drawable matter and of a neutral gas such as air or by means of a viscous or other substance capable of emitting during or before coagulation a gas producing a hollow fiber.
After the gas-cored fiber has been obtained the product is subjected to the action of a fiuid calculated to condense, dissolve or absorb the gas contained within the fiber. The walls that constitute the hollow thread rate after drying, the. product losing its Serial No. 515,324.
rigidity and acquiring remarkable suppleness or pliancy and elongation properties. When the imprisoned gas is air, for instance, water deprived of air by boiling will achieve the result, or the textile fiber may merely be treated with water under pressure. When carbonic acid is employed to produce the hollow fiber, plain water or such baths as areused to treat the thread after its issue from the spinning machine or draw plate will generally quite readily dissolve the imprisoned gas. Of course elimination of the said gas can be either complete or partial.
In the appended drawing, I have shown various sectional views which will make my invention very clearly understood.
Figure 1 is a sectional view of a solid artificial textile fiber, that is to say of an ordinary fiber as seen through a microscope; the shapes of such sections varying very much indeed.
Figure 2 is a sectional view of a hollow artificial textile fiber.
Figure 3 is a sectional view of a hollow artificial textile fiber, from the interior of which the gas has been partly eliminated.
Figure 4 is a sectional view of a hollow artificial textile fiber with the gas practically entirely exhausted. Figures 5 and 6 are theoretical views showing sections of a solid artificial textile fiber and of a hollow artificial textile fiber obtained by the process according to my invention, and allowing a comparison as to siz s.
Figures 1, 2, 3 and 4 afi'ord a clear demonstration of the difierences that exist in cross section between a solid fiber a, a hollow fiber I) with gas inside, and a hollow fiber c from which the gas has been removed by, say, dissolving.
Hereinbefore l have pointed out the advantages ofiered by thread a due to suppression of rigidity and increase of elasticity and suppleness or pliancy; the strength of the product is. also, in many cases, far greater than that of the gas-filled thread, the latter being especially ill-adapted to stand somewhat high temperature either during hot-air drying or when the fiber 1s treated by means of hot baths, which operations frequently cause bubbles to burst, whence a weakening of the fiber.
The product obtained by my new process does not ofi'er this drawback.
Moreover I would call attention to the saving which, in weaving, results from the use of my new hollow thread.
An inspection of Figures 5 and 6 will show that with equal weight, the areaoccupied by matter in the hollow gaswoid fiber is far greater than the one occupied by the same matter when solid drawn or spun, the ratio being about 5:2, and obviously this property is maintained to a high degree in the assemblages of fibers that constitute threads or twists.
It should be understood, of course, that the ejection of the gas contained in the hollow thread can be effected by other means than dissolving, as mentioned. I can, for instance, use progressive action of vacuum or pressure, or both these actions combined. Such means are indicated however only by way of examples.
Having now particularly described and ascertained the nature of my said invention and the manner in which the same is to be performed, what I claim is:
1. In a process of manufacturing hollow, artificial textil filaments, the steps of forming a filament with a filling or core of fluid,-
and then extracting the fluid to cause the walls of the filament to collapse.
2. In a process of manufacturing hollow, artificial textile filaments, the steps, of forming a filament with a filling or core of gaseous fluid, and then extracting. said fluid to cause the walls of the filament to collapse.
3. The herein-described process, comprising th steps of forming a hollow, artificial textile filament having a filling or core of air, and then extracting the air to cause the walls of the filament to collapse.
4. The herein-described process, comprising the steps of forming, from a suitablymatured viscose solution, a hollow thread .or strip having an internal core or filling of gaseous fluid, and then extracting the fluid to cause the walls of the thread or strip to collapse.
The herein-described process, comprising the steps of forming, from a suitablymatured viscose solution, a filament containing air, and then extractingthe air to cause the walls of the filament to collapse.
6. The herein-described process, comprising the steps of forming a hollow, artificial textile filament having an internal .core or filling of gas. and then submerging the filament in a bath which will dissolve the gas and thereby cause the walls of th filament to collapse.
7. As a new article of manufacture, a hollow, artificial textile filament from which the gaseous fluid originally contained therein has been extracted.
8. As a new article of manufacture, a hollow, artificial textile filament of suitablymatured viscose, from which the gaseous fluid originally produced in the filament incidental to its formation has been extracted.
9. As a new article of manufacture, a hollow, artificial textile filament having unbroken. collapsed walls.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
JULES ROUS SET.
