Description

Re: "Method of making a yarn, being a core thread made of wire with a roving made of natural and / or synthetic textile staple fibers is wound twice. "Addition to patent ....... Patent application M 62 888 VIIa / 25c (Receipt at the German Patent Office: October 24th, 64) Subject of the main patent ...., ... (Patent application M 62 888 VIIa / 25c) is a method of manufacturing yarn, being an endless synthetic elastic or inelastic emerald thread or an emerald thread made of natural rubber with roving made of natural and / or synthetic textile staple fibers in one 2-fold spinning process is wound on the spinning machine.

As practice has shown, holds a manufactured according to the invention Yarn withstands all the stresses and strains that yarns encounter during their processing into woven and knitted fabrics and the like or when used as sewing thread, knitting thread or darning thread are.

The casing made of natural or synthetic staple barrels In no case does it detach itself from the core thread. Even yarns that were previously twisted had to be used in order to be used as a chain in a fabric, can now can also be processed untwisted.

The invention relates to a method for producing a yarn, where instead of endless synthetics, the core thread is a wire, for example Made of a chrome-nickel alloy and this core thread is made up of a roving natural and / or synthetic textile staple fibers is wound twice.

Braided wires are known, the wire with finished threads, z. B. made of cotton is braided. It also already has attempts given, to coat a wire with cotton fiber material. The expected success remained however, because the wire, due to its non-textile properties, is constantly passing through his casing grinned through it and thus in many places not from fibrous material could be covered.

Overcoming this disadvantage is an aim of the invention.

A second thing, however, is that there is a wire yarn spun twice there too can be used (for example in a tape fabric, or for sewing threads or elsewhere) where during later processing or when used with extremely high heat is being worked on or the finished piece comes into contact with acids. In such a special case, you cannot use a braided, endless synthetic core thread, because this dissolves at the latest when it reaches its melting point and also is sensitive to acids.

A first braided core thread is produced from wire on the spinning machine. Depending on the desired failure of the finished thread, it can be the core thread made of wire, untwisted in the last pair of cylinders of the drafting system Run in the spinning machine or be turned beforehand.

As the direction of rotation on the spinning machine when sheathing the Wire thread with roving (made from natural or synthetic fibers) can be used both Wire, as well as Z-wire, can be selected, depending on the intended use.

The one produced in this way in the first spinning process and wrapped with fiber material Core thread made of wire is, according to the invention, in a subsequent second spinning process on the spinning machine, a second time to the last pair of cylinders of the drafting system fed and again with a roving, which is made of the same material as in the first spinning process, consists, covered with the yarn number of the roving is adjusted accordingly.

The rotation direction in this second spinning process can be either opposite to the rotation of the first spinning process or in the same Direction of rotation, as in the first spinning process, take place.

If the direction of rotation is opposite in the second spinning process the direction of rotation of the first spinning process, the thread is softer and more voluminous wrapping. But becomes the direction of rotation for the second spinning process the first spinning process maintained, the wrapping is particularly strong and hard, which is common for most of the areas of application for the finished thread known up to now may be required. Instead of one core thread made of wire, two or more Core threads made of wire are used.

Both in the first spinning process, as well as in the second or also in both, it is possible that when using two or more core threads, except the core thread made of wire, one or more core threads are also used in each case can be made from the most varied of raw materials, natural or synthetic Origin, exist, e.g. polyester, polyamide, cotton, cellulose, etc.

Likewise, those produced by the process according to the invention can be used braided wire yarns twisted or corded with one another in a known manner will.

The sheathing of the wire from natural and / or synthetic In any case, staple fibers will no longer come off and the wire is complete with fiber material covers and has the appearance of a normal textile thread.

Areas of application that have already been developed for the braided wire yarn, according to the invention, are: tapes and belts, technical fabrics and fabrics for filter fabrics, Tissues for medical purposes e.g. B. Bandages, fabrics for protective clothing, as well as sewing threads.
