JOHN GRANT JACKSON, OF C'EATHAM, ONTARIO, CANADA.
METHOD OF PRODUCING FILAMENTARY MATERIAL.
Application filed January 15, 1827. Serial No. 181,874.
My invention relates to improvements in filamentary materials and methods for producing same, and the object of the invention is to devise a method of treating filamentary materials whereby their flexibility is greatly increased.
A further object is to produce filaments which when formed into yarns or fabrics will result in a more coherent product than is the case where the filaments are not so treated.
By my method I take a filament which-is either initially formed in, or is reduced to, a liquid or plastic state and impress thereon a vibrating wave eflt'ect and simultaneously cause the said filament to become fixed intoa solid state with the result that it assumes a permanently waved form.
To carry out my invention I may employ for example, in the case of materials susceptible to being squirted into filamentary form, a nozzle for squirting the filamentary material in a liquid or plastic state into a bath of fixing solution as. in any of the well known methods for the production of arti- I ficial silk or the like, and a vibratory diaphragm for directing upon the squirted filamentary material after it emerges from the nozzle, through the medium of the fixing solution, a vibratory wave efiect which imparts to the filament a waved form corresponding thereto.
I will now describe the apparatus employed, more particularly re erence being had to the accompanying drawing in which Fig. 1 represents a diagrammatic view of a an apparatus suitable for carrying out my method on'squirted filaments, and
Fig. 2 is adiagrammatic view of a suitable apparatus for carrying out my method in the case of fusible filaments.
Referring to the apparatus depicted in .Fig. 1, 1 is the nozzle adapted to squirt the liquid or plastic material A in a filamentary form B into a bath 2 of fixing solution. 3
is a tube communicating with the bath and filled with fixing solutlon therefrom, said tube bein provided with adiaphragm 4 vibrated y an electroma et 5 ener ized by an alternating current 0 any desire frequency.
When the filament to be treated is of the type which is reduced to the liquid or plastic state by heat and then solidified by cooling as in the case of fibres made from vitreous materials, the squirting nozzle 1 is, of course, not required, being replaced by means for feeding and reducing the filament to molten form. The fixing solution is also'replaced by a cooling medlum which may take the form of an air blast in which case the vibratory wave effect generated by the diaphragm will be impressed upon the air constituting the cooling medium so that the filament will be subjected to the impressed wave effect at the same time as it is being cooled and solidified. An apparatus for the application of my method to such material is clearly illustrated in Fig. 2 of the drawing in which B represents the fusible filament fed down by the feed rolls 6 past the impinging heated gas jets from the nozzles 7 which fuse the filament which is subsequently cooled and solidified by the impinging cold air blasts from the nozzle 8, one of such nozzles 8 being provided with the diaphragm 4vibrated by the electromagnet 5 energized in the same manner as the electromanget 5 (Fig. 1).
Although I have described and illustrated the impressing of a wave effect upon the filaments treated through the fixing or solidifying medium I may produce the same result by applying the vibratory wave effect in any other way which willimpart such effect to the filament while it is being chan ed from a liquid or plastic state to the solid orm.
A filament formed by my method will possess the advantage that there will be no tendency for it to assume a straight form as would be the case where such filament is waved after solidification.
What I claim as my invention is:
1. A method for increasing the flexibility and elasticity of formed filaments which consists in impressing thereon while in an unsolidified state a vibratory wave effect, and causing such filament to become solidified while so acted upon whereby the filament as- 100 sumes a permanently waved form.
2. A method for increasing the flexibility and elasticity of formed filaments which consists in impressing thereon while in an unment being transmitted throng the solidi- 11o fying medium.
