MANUFACTURE OF ARTIFICIAL SILK, ARTIFICIAL HORSEHAIR, AND THE LIKE. No Drawing. Application filed June 28, 1923, Serial No. 648.350, and in Great Britain August 11, 1922.
This invention relates to the manufacture ing or scintillating effect which is sometimes of artificial silk, artificial horsehair or like possessed by filaments or threads formed by threads or filaments from solutions of celluevaporative or dry spinning from solutionslose acetate in particular, but applies also to of the relatively low concentrations usually their production from other solutions ofesemployed, and possibly due to the sectional 60 ters of cellulose or of ethers of cellulose such configuration of the filaments resulting from for example as ethyl-, methylor benzyl celthe spinning of such solutions, by the lulose, or from mixtures of any of such celludry or evaporative method of formation. lose derivatives, all of which solutions are This glitter coated efiect or glitter-pro 10 hereinafter included in the term cellulose ducing structure of the filaments or the 65 derivative solutions. The invention solely like can in some cases be a disadvantage. concerns processes in which the artificial For example, in cases where 'goods in hank, threads or filaments are produced by the dry Woven or knitted fabric or other form, or evaporative method of formation, that is made with threads showing such glitter efto say by extruding a solution of the cellulose feet are dyed in black or dark colours, it is 70 derivative or derivatives in or containing a sometimes found that the d ed goods give an volatile or Vaporizable solvent or solvents, impression as if the arti eial silk is dyed through jets or spinnerets into a heated or only partially or not deep enou h or that other atmosphere in which the filaments or they have aWorn a pearance, this eing more threads solidify by evaporation of solvent. especially seen in abrics. In particular the invention relates to the By formin the dry spun threads, filaments manufacture of threads, filaments or the like or the like from cellulose acetate solutions from cellulose acetate solutions, by dry or for example, of high concentrations such as evaporative spinning. before referred to, it will be seen that the fil- In the manufacture of artificial threads or aments or threads are stronger than those 80 filaments from solutions of cellulose acetate made from solutions of the usual low conor other cellulose esters or ethers such as recentrations, not so liable to crinkle or turn ferred to by the evaporative method, it is Woolly as a result of the action of hot water, usual to employ spinning solutions of relaand moreover that glitter or glitter-produc- 3o tively low concentration, containing not more ing structure is obviated or greatly reduced, 5 than about 16 per cent of the cellulose derivawith its tendency to give on dyed goods, and tive or derivatives in the solvent or solvents especially goods dyed in black or dark colused. ours, the appearance before referred to.
It has now been found that by employing The following are two examples of spin- 5 for the dry or evaporative spinmng solutions ning solutions which may be employed 32- 90 of substantially higher concentrations, concording to the invention, it being understood taining not less than 20% and preferably not that these are given only by way-of illustraless than 25%, e. g., about 25 to or more tion and that other solvents or solvent mixof the cellulose derivative or derivatives and tures may be employed and that the concenespecially in the case of cellulose acetate solutrations can be varied without departing 95 tions, artificial threads or filaments of im-. from the invention.

It is moreover a found that, especially in the case of cellulose Cellulose acetateis dissolved in acetone con- 10:; acetate, the employment of solutions of high taining about 5 to 10 per cent of alcohol and concentrations as referred to has the further about 5 per cent of water, in a quantity to advantage of obviating or reatly reducing give a solution containing about 20 to 30 or f t e what may be called glitter 0 threads, cent, preferably about 25 to 30% of cellu ose y filaments or the like, that is to say, a glitteracetate in the solvent mixture. 3

What I claim and desire to secure by Letters Patent is 1. Process for the manufacture of artificial filaments and threads,'characterized in that the same are dry spun from concentrated solutions of organic substitution derivatives of cellulose containing not less than per cent of cellulose derivative.
2. Process for the manufacture of artificial filaments and threads, characterized in that the same are dry spun from concentrated cellulose acetate solutions containing not less than 25 per cent of cellulose acetate.
3. Process for the manufacture of artificial filaments and threads, characterized in that the same are dry spun from solutions of cellulose acetate containing 25 to about per cent of cellulose acetate.
In testimony whereof I have hereunto subscribed my name.
