y (Cl. 57-160) The present invention relates to textiles and to the manufacture thereof andmore particularly to the type of yarn which maybe used for trimming and for the manufacture of imitation Persian lamb cloth.

Past efforts have succeeded in the manufacture of cloth which closely simulates the appearance the cloth and articles such as coats made therefrom have a consumer appeal. they do not have the wearing qualities desirable for their extensive adoption. The present inventionv aims to provide a textile which may be used in making t a fabric to simulate Persian lamb fur and which is durable and therefore satisfactory for the manbeen chosen for purposes of illustration and description and vis shown in the accompanying drawing, forming a part of the speciilcation, wherein Fig. 1 is a fragmentary view of a fabric illustrating a preferred method of making the :IiatI i strandsV of chenille;

' of Persian lamb fur. :in some cases, this has been rf.A done by sewing a curled chenille yarn to a backlighter portion illustrating the fibers at points ufacture of coats and other articles therefrom` andat the same time lower in cost.

An object of the invention is to provide an improved, inexpensive, durable textile which may be utilized for trimming and for the manufacv ture of artincial Persian lamb fabric.

Another object ofthe invention is to provide an improved method of making a textile for the manufacture of artificial fur and the like.

Another object of the invention is to provide a textile which will produce a heavier cloth and hence more nearly simulate a fur.

Another object of the invention is to provide a wrapped textile wherein the wrapping will not slip on the core.

Another object of the invention is to provide a yarn with a core of a heavy material and a Fig. 2 is a side elevational view of a strand of flat chenille;

Fig. 14 is a fragmentary top plan view of a piece of cloth embodying the present invention;

Referring again to the drawing and morepar- A preferred embodiment of the invention has so ticularly to Fig.i, a preferred method of making the strands of fiat chenille is illustrated. There is shown a series of warp threads I which may be any desired number and between these warp threads, a fibrous material such as cotton is wo-l ,l 4-4 of Fig. 1. This cutting operation provides a large number of strands of flat chenille similar to the single strand shown more particularly in Figs. 2 and 3 at a very low cost due to the large t number of strands made in the weaving and cutting operations. Groups of fibers 2 forming the weft threads are held together between the two warp threads I so that the cutl ends of thefiibers project outwardly therefrom, as shown more particularly at Fig. 3 to provide a strand of fiat chenille. This method of manufacture facilitates mass production and lowers materially the unit cost.

In order to provide a yarn having a smooth outer surface which may be made into a cloth which simulates Persian lamb, the strand of chenille shown in Figs. 1 and 2 is passed through the bore 5 of a bullet shaped device 6. vA member 1 is adapted to revolve about the tapered end 8 of the device 6 to apply a wrapping thereon which is removed and backed up by the compressed fibers of the strand of chenille emerging from the end of the tube. In this way, the flat strands of chenille are wrapped to give a smooth outer covering and to retain the outwardly projecting fibers of the core enclosed. The wrapping may be as tight as desired, but generally is loose to give a soft yarn. which may be readily bent without exposing the inner core when sewed on a backing for forming a cloth. In this way, a less expensive and more durable yarn is provided. In order to prevent slippage between the outer wrapping' and the inner core and in order to increase the weight of the material, the fiat strands of chenille are preferably made of cotton which weighs considerably more than rayon or silkand are thereafter wrapped with a silklike material shown as a thread or yarn such as silk or rayon togive an external appearance which simulates Persian lamb. The greater friction occasioned by the contrasting materials of the core and wrapping tends to prevent slippage between the two and provides va more durable yarn and one in which the covering is less likely to spread and expose the inner core. l, j

In some cases, it may be desired to provide a more nearly circular core, and a firmer core.

so that any tendency of the core to untwist will cause the wrappinsr to grip tighter.

By wrapping a plurality of strands of twisted chenille 2 and 2', as illustrated in Figs. 8, 9 and 10, the body and weight of the core may be further increased and a more nearly circular form obtained. The inexpensive method of manufacturing the fiat chenille permits this to be done without unduly increasing the cost of the finished yarn. In each of the above cases, it is preferred to have the core made of cotton and the/exterior wrapping of a silk-like material: but other materials may be utilized for both thel core and the wrapping within the scope of the invention.

While excellent results may be obtained with l the above yarns, in some cases it may be desired to guard even further against the wrapping slipping with respect to the core and against the wrapping exposing the core. There is illustrated in Fig. 12 a device similar to that shown in Fig. 1l with a conduit I0 which enters the tube atthe nipple II and passes longitudinally through it to permit an adhesive to be conducted to the This may be done as shown in Figs. 5, 6 and '7 by twisting the fiat chenille so that the outer fibers 2 on each side will form a sort of spiral. If twisted suiiiciently, the free ends of the fibers 2 will engage the cuter wrapping substantially about the entire circumference. This gives a firm core and causes the outer wrapping to be Ymore nearly circular in the finished yarn. The side view in Fig. 5 shows the effect of twisting the fiat yarn,

the free ends thereof forming in effect a spiral extending about the core. The darker portion of the section in Fig. 5 shows the fibers at the plane of section and the lighter portions show the fibers at planes from the plane of the section. A section through the finished strand after it is wrapped is illustrated in Fig. 4. The fibrous material 9 may be wrapped about the twisted chenille described above and in connection with Figs. 8 to 10 in a direction opposite to the twist small end of vthe tube where the .wrapping is being applied to the core without impairing in any way the wrapping operation. One or more conduits I0 may be utilized if desired in applying the adhesive to the exterior of the core as it is being wrapped. The advantageof applying it at the outlet en'd is to minimize the adherence of the glue to the inside of the bore 5 and to apply it to the core just prior to the, application 'of the wrapping. The adhesive is preferably thin and preferably formed from a latex base so that it does not show on the exterior of the wrapped yarn but is confined to the outer surface o'f the core and the inner surfaceof the wrapping 2. If desired, the adhesive maybe applied to the core prior to its entrance to the tube member 6 by passing the strand of yarn over a roller I2 having its lower` surface immersed in the adhesive I4 in a reservoir I 5. The inner bore 5,

` cost than previous yarns.

It will be seen that the present invention provides an improved yarn and an improved method of manufacture. The yarn is more durable and less expensive than yarns heretofore and may be utilized for the manufacture of trimmings and for the manufacture of imitation .Persian lamb fabric. The use of a cotton core of flat chenille with a silk-like wrapping increases the weight without increasing materially the cost and at the same time prevents slippage between the covering and the core by having contrastingv materials and outwardly projecting fibers which may v be engaged by the wrapping. The use of fan adhesive further prevents slippage between the core and the outer wrapping without, impairing the appearance of the yarn. The resulting cloth is able to withstand the rough usage to which it may be subjected.

As various changes may be made in the'form,

construction andl arrangementl of the parts herein without departing from the spiritand scope of the invention andwithout sacrificing any of its advantages. it is to be understood that all matter herein is to be interpreted as illustrative and not in a limiting sense.
