To all to 7mm it may concern:

Be it known that I, OASIMIR ZEGLEN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Methods of iVeaving Fabric from Rubberized Yarn, of which the following is a full, clear, and exact description.

This invention relates to a process of weaving fabric from rubberized yarn or threads for the purpose of producing rubberized fabric capable of being used for a variety of purposes, such for example, as the manufacture of automobile tires, belting, hose, garments, air ships, particularly of the inflatable type, etc.

It is a well-known fact that yarn or threads (hereafter termed yarn for convenience) rubberized with unvulcanized rubber cannot be woven into fabric in view of the sticky character of the yarn. A great deal of time and labor has been spent to devise a method of treating or handling the rubberized yarn in such a Way that it could be woven in a fabric, but so far as I am aware, these attempts have been failures. For example, it has been proposed to attempt to semi-vulcanize the. rubberized yarn, but this has not proven satisfactory, and it has been proposed to'coat the yarn with a substance generally in powdered form to eliminate from the surface of the yarn its sticky characteristic, but this likewise has been unsuccessful, for as far as I am aware, anything which could be applied to the rubber covered or impregnated yarn so as to successfully eliminate the sticky characteristic interfered with or prevented vulcanization.

The method which I have devised is simple, inexpensive, and does not in the least interfere with vulcanization or affect the quality of the fabric before or after vulcanization.

In carrying out my invention the vulcanized yarn, both the weft and warp yarn is immersed in water, or is otherwise placed in a wet condition by water applied in any suitable way so that during the weaving the yarn is wet. The presence of water on the rubberized surface of the yarn takes away the sticky adhesive character so that the yarn does not stick together, nor

does the rubber prevent the proper and desired weaving, but nevertheless after the fabric is woven and is dried, the fabric can be vulcanized as effectively as if the yarn had not been subjected to the wetting process.

It is, of course, immaterial to my invention how the yarn is rubberized. It can be done with the well-known impregnating process wherein the yarn is run through a bath of rubber cement or rubber dissolved in a suitable solvent, or by a brushing or scrubbing process, or any of the other impregnating processes in use at the present tlme.

It is also immaterial to my invention in just what manner the yarn is placed in the wet condition, or how the yarn is maintained wet to enable the rubberized yarn to be woven. It is important, however, that the different layers of the yarn on the spools and bobbins be in wet condition from the outer surface to the inner surface of the spool or bobbin. However, in winding the rubberized weft yarn onto bobbins and the rubberized warp yarn onto spools, the yarn is preferably passed through a tank or receptacle of water so that it will become thoroughly wet, and if desired, after the bobbins and spools have been wound, they may be kept immersed in water, or just prior to being used in the loom they may be immersed in water to again thoroughly wet the outer layers which may have become more or less dried.

Thus by the simple process of maintaining the rubberized yarn in wet condition I am enabled to successfully weave the rubberized yarn, and this can be done without adding to the cost of the weaving and without in any way affecting vulcanization or otherwise affecting the character or quality of the fabric.

Having thus described my invention, what I claim, is: i

1. In the process of weaving fabric from rubberized yarn, the method of preventing the yarn sticking together which comprises wetting the rubberized yarn immediately preceding the weaving.

2. The step in the method of Weaving to remove the sticky characteristic, and

then Weaving the yurninto the fabric While inv its net condition. 10 In testimony whereof I hereunto afi i x my signature. i
