J., assignor to Duro Persian Manufacturing Co., Inc., East Newark, N. J., a corporation of New Jersey @riginal application April 28, 1942, Serial No. 440,783. Divided and this application Qctober 3, 1944, Serial No. 556,987

The present invention relates to textiles and to the manufacture thereof and more particularly to the type of yarn which may be used for trimming and for the manufacture oi' imitation Persian lamb cloth.

This is a division of my application Serial No. 440,783, iled April 28, 1942, Patent Number 2,374,631, granted April 24, 1945.

Past eiorts have succeeded in the manufacture of cloth which closely simulates the appearance of Persian lamb fur. In some cases, this has been done by sewing a curled chenille yarn to a backing. In other cases, a Wrapped material has been secured to a cloth backing. One of the difliculties encountered is the poor wearing quality of the cloth. The cloth, when rubbed against other objects, loses its nished appearance and takes on a shaggy appearance. Persons not knowing that this is an inherent characteristic of the cloth complain to the stores selling it, claiming that the material is defective and of poor quality. Stores, in order to prevent impairment of their reputation, are inclined to discontinue sales of the material and of articles made from it. Thus, While 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 invention aims to provide a textile which may be used in making a fabric to simulate Persian lamb fur and which is durable and therefore satisfactory for the manufacture of coats and other articles therefrom and at 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 manufacture of articial Persian lamb fabric.

Another object of the invention is to provide an improved method of making a textile for the manufacture of articial 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 Wrapping of a silk-like material which tends to adhere to the core.

Other and further objects of the invention will be obvious upon an understanding of the illustrative embodiment about to be described, or will be indicated in the appended claims, and various advantages not referred to herein Will occur to 4 Claims.4 (Cl. 57-149) one skilled in the art upon employment of the invention in practice.

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

Referring again to the drawings and more particularly to Fig. l, a preferred method of making the strands of ilat 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 woven as weft threads. Cloth of any desired Width may be woven rapidly in this manner by suitable automatic machinery. Thereafter a series of cutters may be utilized to cut the cloth intermediate the warp threads; for example, along the line 4 4 of Fig. 1. This cutting operation provides a large number of strands of at chenille similar to the single strand shown more particularly in Figs. 2 and 3 at a very low cost due to the large number of strands made in the weaving and cutting operations. Groups of bers 2 forming the weft threads are held together between the two warp threads I so that the cut ends of the bers project outwardly therefrom, as shown more particu larly at Fig. 3 to provide a strand of flat 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. l and 2 is passed through the bore 5 of a bullet shaped device 6. A member l is adapted to revolve about the tapered end 8 ofthe device -6 to apply a wrapping thereon which is removed and picked up by the compressed bers 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 t 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. between the outer wrapping and the inner core and in order to increase the weight of the material, the flat strands of chenille are preferably made of cotton which Weighs considerably more than rayon or silk and are thereafter wrapped with a silk-like material shown as a thread or yarn such as silk or rayon to give 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 a more durable yarn and one in which the covering is less likely to spread and expose the inner core.

In some cases, it may be desirable to provide a more nearly circular core, and a rmer core. This may be done as shown in Figs. 5, 6 and 7 by twisting the flat chenille so that the outer bers 2 on each side will form a sort of spiral. If twisted sufficiently, the free ends of the bers 2 will engage the outer wrapping substantially about the entire circumference. This gives a rm core and causes the outer wrapping to be more nearly circular in the inished yarn. The side view in Fig. shows the effect of twisting the flat yarn, the free ends thereof forming in eifect a spiral extending about the core. The darker portion of the section in Fig. 5 shows the bers at the plane of section and .the lighter portions show the fibers at planes from the plane of the section. A section through the iinished strand after it is wrapped is illustrated in Fig. 4. The fibrous material 9 may be wrapped about the In order to prevent slippage twisted chenille described above and in connection with Figs. 8 to l0 in a direction opposite to the twist so that any tendency of the core to untwist will cause the wrapping 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 iurther 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 iinished 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 the core and the wrapping within the scope of the invention.

While excellent results may be obtained with 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. 11 with a conduit lil which enters the tube at the nipple H and passes longitudinally through it to permit an adhesive to be conducted to the small end of the tube where the wrapping is being applied to the core without impairing in any way the wrapping operation. One or more conduits iii may be utilized if desired in applying the adhesive to the exterior of the core as it is being wrapped. The advantage of applying it at the outlet end 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 conned to the outer surface of the core and the inner surface of the wrapping S. If desired, the adhesive maybe applied to the core prior to its entrance to the tube member 5 by passing the strand of yarn over a roller I2 having its lower surface immersed in the adhesive lli in a reservoir l5. The inner bore 5 will spread the adhesive on the surface of the core.

The yarn illustrated in Figs. fi, 7, l0 and l1 may be sewed or otherwise secured to a backing l5 as illustrated more particularly in Fig. 14 to provide a cloth which simulates artificial Persian lamb. It will be understood, of course, that the yarn can also be used for various trimmings. In all cases, it is more durable than yarns heretofore and may be made of a heavier weight at less 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 at 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 contrasting materials and outwardly projecting iibers which may he engaged by the wrapping. The use of an adhesive further prevents slippage between the core and the outer wrapping without irnpairing the appearance of the yarn. The resulting cloth is able to withstand the rough usage to which it be subjected.

As various changes may be made in the` form, construction and arrangement of the parts herein without departing from the spirit and scope of the invention and without 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.

Having thus described my invention, I claim:

1. A strand of textile material comprising a plurality of entwined strands of flat chenille as an inner core and a strand of silk-like material Wrapped thereabout substantially to cover the same.

2. A strand of textile material comprising a strand of chenille as a core and twisted in one direction, and a strand of material wrapped about said core in the opposite direction to form a covering therefor.

3. A strand of textile material comprising a plurality of strands of iiat chenille lying against and twisted about each other to form a core, and a strand of textile material Wrapped around said strands to hold them together to form a unitary yarn.

4. A strand of textile material comprising a strand of cotton chenille as a core twisted in one direction and a strand of silklike material 6 wrapped about said core in the opposite direction to form a covering therefor, the increased frictional grip occasioned by the differences in material minimizing slippage therebetween.
