HANUFACT'P'RE AND TREATMENT OF THREADS.

Ho Drawing. Original application flied August 27, 1825, Serial No. 513,988. Divided and this application flled lleroli 1, 1988. Serial No. 91,619. 1

My invention relates generally to the man- 1 ufacture and treatment of threads to be made up into or forming part of a fabric, and has particular reference to a method of pro- 6 ducin or treating such threads to rovide irre u arities therein so as to have t e fab ric ormed therefrom ornamented ,by'such irre larities and is a division of my copen in application Sen-N0. 52,958, filed 10 Aug. 2 1925.

In accordance with onedisclosure of my invention, material like viscose is de osited in accordance with a predetermine (plan, upon a fabric or its constituent threa s or associated with the threads during or after the formation of the thread.

For the attainment of the foregoing ob jects and such otherobjects as may herein after appear or be pointed out, I shall now de- 2 scribeseveral processes which are illustrative of possible modes of carrying out my invention.

Itis a well known fact that silk thread which is obtained from imperfect or freak cocoons, or from the cocoons of wild or uncultivated silkworms, will be irregular in contour and thickness and will carry hubs or slubs, or thickened ortions at frequent.

iular intervals. ese very imperfections, however, have been utilized to effect an irre lar, yet pleasing, ornamentation upon fa ric, by manufacturin the fabric of these imperfect threads. Suc silk threads are extremely limited in quantity,-and difficult to select'and obtain, and therefore eirpensive.

One of the objects of my invention is the roduction of a thread which simulates these imperfections and more partic'ularl the production of a. thread predetermine 1y simulating these imperfectidns so as to permit of the production of a fabric predetermined- 1y ornamented. One method of carrying out my invention lies in directly deppsitinv'u on or causing to be associated wit an a rea y formed base 3 thread, preferabl though not necessarily of silk or artificia silk or uponan artificial thread' simultaneously with its formation, masses of viscose of past consistency, at reg- 4 ular or irre with a pre etermined plan to simulate the lar interva s, and in accordance 1m Wl iere the imitated nubs are associated with an already formed thread, the viscose is pref-' erfect threads hereinbefore referred to;

erably prepared in the form of a pasty mass,

and made available as re uired. Pnedetermined quantities or obs o the mass may be deposited upon the use thread at suitable irregular intervals, and the inherent characteristics of the viscose will cause it to harden reel of the thread and to become part and in such a manner that t e resulting thread will be hardly distin uishable from the genuine product obtained from the uncultivated cocoons. The fabric is then woven in a well known manner, and ornamentations will resuit which will be artistically irregular in accordance with the predetermined plan. It will be obvious that a modification of this process will permit of the deposit of viscose masses at regular intervals, if desired, in accordance with any redetermined or desired artistic scheme, an the resultin fabric will have an unusual ornamenta effect, in that it will appear to have been made from imperfect genuine silk threads, yet hearing at the same time designs having certain features of regularity. I

It will be under 0111 hat my invention further includes the formation in accord.- ance with my process of nubs, irregulari-- ties or deposits which may be given or made 7 to simulateany desired geometrical or other design, as for instance,- round, square, ortriangle dotsv and that the formation of deposits, nabs or irregularities having these redetermined shapes or configurations may,

no to-the redetemiined shapes'and confi rations form a very important feature of the ultimate design to be given the fabric. The nubs, irregularities or deposits can likewise be given their predetermined shape or configuration as aforementioned during their" formation or association with the threads or even after such association and regardless of whether it is the thread before weaving which is operated upon and whether during or after formatiomor the fabric after the threads are woven into a, fabric. 7

, Another method of carrying out my invention is the result of carrying the basic idea a step further., Instead of depositing the viscose at regulanintervals upon a base deposits will become part and parcel of the Ade thread and thereupon weavin the fabric, it is possible and 0 en prefera le to deposit the viscose in accordance with a predetermined lan of treatment upon the, threads of a finished base fabric, that is, upon a fabric already woven. In accordance with th s method, the base fabric, such as cotton, may be rendered ornamental by directly depositing viscoseupon the threads thereof in predetermined quantities and masses and along redetermined threads and at predetermined intervals, and by virtue of the fact that the base fabric, the result will be one of a fabric bearing not only silk ornamentation but these in the form of nubs or thickened portions. 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. The viscose s depositeddirectly upon the base fabrlc threads at points dependent upon the particular'ornamentation which, has been .decided upon. Thereupon the deposited material is allowed to dry, whereby it will become closely associatedwith the fabric in a manner to become part and parcel'thereof. ition process similar to printing may also e 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, the advanta es 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 besuitably colored before application, or that suitable coloring matter 'inthe form of a deposited powder or the like may be added to it after it has been applied or associated with the fabric or to the thread.

It is a well known fact that in the manufacture of artificial silk, imperfections frequently arise primarily because of the breakage or unevenness in oneor more of the filaments that go to make up a thread and these imperfect threads are classified according to the degree of imperfection. vSome of the threads are so imperfect as to have relatively small value. My invention contemplates taking threads of this character, and of little value for ordinary commercial use, and converting them into threads with nubs or protuberances thereon or associated therewith and which threads. as stated, are of greater value than even the perfect threads.

5 ornamentalfabric, which .consists in depositart without departing from thespirit and scope of the invention, and it is therefore intended that these details be interpreted'as illustrative and not in a limiting sense. I For instance, the irregularities mi ht be producd by the manner in which t e thread is formedor by treating the already formed thread itself and without depositing any additional material or substance thereon.

Having thus described my invention-and illustrated its use, what I claim as new and desire to secure by Letters Patent is: 1. The herein described process of making threads to be employed in the manufacture of fabrics to simulate fabrics made from silk threads obtained from uncultivated silk worm, cocoons with irregularities thereon, said process consisting of associating such irregularities with the thread after the threads are formed, 2. The herein described process of making threads to be em loyed in the manufacture of fabrics to simu ate fabrics madefrom silk threads obtained from uncultivated silk worm, cocoons with irre said process consisting o associating such mined intervals after the threads are formed. 3. The herein described process of making threads to be employed in the manufacture of fabrics to simulate fabrics. made from silk threads obtained from uncultivated silk worm, cocoons with irregularities, thereon, said process consisting of associating viscose nubs with the thread after the threads are formed. 4. The herein described rocess of making a thread to be employe in the production of a fabric to simulate'that made from silk threads obtained from the irregularly formed thread of the uncultivated silk worm cocoon, said recess including the formation of a thread rom viscose and the association therewith of irregularities by predeterthe thread.

larities thereon,

'5. The herein described process of making ornamental fabrics, which consist in'depositmg vlscose at predetermined intervals upon a ase thread to simulate the irregularities of silk thread obtained from uncultivated,-

silk worm cocoons, and thereupon weaving a fabric of said thread.

- 6. The herein described process of making 1" ornamental fabric, which consists in depositing predetermined masses of viscose in [a pasty condition upon a base thread of silk at predetermined irregular intervals,-- and thereupon weaving a fabric of said thread.

7. The herein described process'of making 5 y in}; predetermined masses of viscose in a thereupon weaving a fabric of said thread.

8. A fabric formed in simulation of one made from irregularly formed threads obtained from uncultivated silk worm cocoons, said fabric having irregularities in the threads formed artificially after the formation of the thread.

In witness whereof, I have hereunto signed my name this 26 day' of February, 1926.
