PROCESS OF MAKING THREAD.

No Drawing.

a method which is extremely inexpensive, reliable requiring no particular skill, and productive of sur-.

prising and novel results.

Where I have attempted to produce ornamentations upon a fabric base by the deposit of a plastic mass thereon, I have found that the plastic masses hitherto employed by me have been of such a character that in order to give the desired ornamental effect, the

0 de osited material had to be treated either be ore or after the de osition thereof, as by flocking, so as to pro uce the desired result. More specifically, where the effect desired was an ornamentation which would resemble the effect produced by the utilization of genuine silk thread, the material deposited, in general had to be treated with a coloring matter which would impart to the surface of such deposited material an appearance of silk. 7

' Accordingly, another object of the present invention is to provide a method of producin a fabric of this nature, wherein the necessity for such treatment has been eliminated, and wherein the material deposited will in and of itself and by virtue of its own inherent characteristics produce the desired efi'ect. I 40. More specifically, it is an object of the invention to produce a fabric of this character which will resemble the type of fabric which is produced by the utilization of silk thread which has been obtained fI'OIIlllIlCllltivated silk worms.

Another dbject is to produce a fabric which will bear ornamentations of the na 'ture and appearance of silk embroidery, without however encountering any of the difliculties or expense generally involved in genuine embroidery work. A feature of the invention lies in the direct deposition of a material like viscose in accordance with a predetermined plan, upon a fabric or its constituent threads.

For the attainment of the foregoing ch- A further object lies in producing such Application filed August 2 7, 1925. Seriallio. 52,958.-

jects and such other objects as may hereinafter appear or be pointed out, I shall now describe several processes which are illustrative of possible modes of. carrying out my invention.

It .is a well-known fact that silk thread which is obtained fro m imperfect or freak cocoons, 'or from the-.;cocoons of wild or uncultivated silk 'worms,"will be irregular in texture and will carry nub s,.or thickened portions, at frequent irregular intervals. These very imperfections, however, have been utilized to effect an irregular,yet pleasing, ornamentation upon fabric, by manu- 3 facturing the fabric of these imperfect threads.

One of the objects of my invention is the production of a thread which simulates this imperfection, and more particularly the proferred to. Where the imitated nubs are as ,sociated with an already formed thread, the

viscose is preferab y preparedv .in' the form' of a pasty mass, and made v available as require re-determined quantities or obs of the mass may be depositedupon the ase thread at suitable irregular intervals, and the inherent characteristics of the viscose will cause it to harden and to become part and parcel of the thread in such a manner that the resulting thread will be hardly dlS- tinguishable from the genuine product obtained from the uncultivated cocoons. The f.

fabric is then woven-in alwell-known man- 'ner, and ornamentations will result which will be artistically irregular in accordance with the redetermined plan/ It will this process will permit of the deposit of viscose masses at regular intervals, if dee obvious that a modification of sired, in accordance with any predetermined or desired artistic scheme, and the resultin fabric will have an unusual ornamental e set, in that it will appear to ave been .made from imperfect genuine sil threads,

yet hearing at the same time designs having certain features of regularity.

In order to carry out and fully attain the objects of my invention, I may control or vary the quantity of thread material thereby forming the irregularities, nubs, or thickened portions and I preferably, although not necessarily, do this in a predetermined manner so as more effectively to produce the new and desired results. This controlled or predeterminedly controlled varying of the quantity of material may be accomplished in many ways. As Jan example, I may obtain a surging action by providing for the irregular operation of the pump acting to force the vicose material through the dies, whereby the viscose material is more or less rapidly forced through said dies at the irregular impulse strokes of the pump. This has been found to effectively produce the intended results as the irregular impulses may readily be given to the pump through the use of cam arrangements. Such an arrangement would, moreover, lend itself to any desired predetermined control as the cam faces can be contoured to give any predetermined or controlled irregularities. As a further example of an eflicient manner of carrying my invention into effect, I may associate with the main pump forcingthe viscose material through the dies, an auxiliary pump which may vary the pressure at the extruding orifices of the dies, or the amount of material passing therethrough in a given time, or both, and thus again fully effectuate my present invention.

Another method of carrying out my invention is the result of carrying the basic idea a step further. Instead of depositing the viscose at regular intervals upon a base thread and thereupon weaving the fabric, it is possible and often preferable to de osit the viscose in accordance with a pre etermined plan of ornamentation upon a finished base fabric, that is, upon a fabric already woven. In accordance with this method, a base fabric, such as cotton, may be rendered ornamental by directly depositing viscose thereon in predetermined quantities and masses and along predetermined lines or areas, and by virtue of the fact that the deposits will become part and parcel of the ase fabric, the result will be one of a fabric bearing silk ornamentations. In accordance with this method, the material which has been selected as a base, either silk or non-silk, as desired, is suitably laid out and may if desired be stenciled or similarly imprinted in a temporary manner with the particular design in contemplation, although this preliminary outlining of the design is not an essential step. Viscose is then prepared in the same manner as hereinbefore described, namely, in the form of a pasty mass, and is made suitably available in any preferred manner. One method of rendering the viscose available for this purpose is to insert it into a plurality of tubes having outlet openings of varied sizes and configurations, whereby viscose streams of desired thicknesses or mass may be expelled by pressure uponthe tubes. The tubes are then manipulated in any desired or preferred manner as in the manner of pencils, and the viscose is deposited directly upon the base fabric along lines or areas dependent in size, length, and configuration upon the particular ornamentation which has been decided upon. Thereupon the deposited material is allowed to dry, whereby it will become closely associated with the fabric in a manner to become part and parcel thereof. A deposition process similar to printing may also be employed.

In cases where the deposits have been made along lines simulating. embroidery, the resulting ornamentation will not only resemble genuine embroidery, but will consist of actual artificial silk integrally associated with the fabric as though genuinely produced by embroidery processes. Accordingly, theadvantages of silk embroidery work are obtained without any of its disadvantages having been encountered.

Although not essential, it will be obvious that the viscose may be suitably colored before application, or,that suitablecoloring matter in the form of a deposited powder or the like may be added to it after it has been applied to the fabric.

It will be obvious that various changes in the details as herein described for the purpose of explaining the nature of my invention may be made by those skilled in the art without departing from the spirit and scope of the invention as expressed in the appended claims, and it is therefore intended that these details be interpreted as illustrative and not in a limiting sense.

It will be observed that in the specification and claims the term thread material is-intended to apply to the material forming the thread, whether plastic or otherwise. or to the subsequently formed thread.

The irregularities herein referred to have been described as simulating those formed by the uncultivated silk worm cocoon. It will be understood, however, that such need not be the case.

In the claims where I make reference to forming a fibre or thread with irregularities thereon by associating with the thread materials such irregularities by. a predetermined controlled or varying quantity of material, I mean to include thereby such additions or variations as will give an irregular or ornamental effect in accordance with some predetermined scheme or plan to obtain effects of definite irregularity, and not merely accidental, such as might be caused by an improper handling of the mechanism or coagulating baths affecting merely in an undesired manner the filamentor thread for purposes of weaving, knitting or otherwise handling the filament or thread for forming a fabric.
