Process for straightening and finishing yarns.

Patented in the German Empire on February 17, 1878.

The purpose of this invention is to use yarn made from wool or other soft hairs such as z. B. camel hair, alpacca, angora, or yarns, which are made of a mixture of one or more Such types of hair should be treated in such a way that they give them considerably more strength and the same will be significantly improved in quality.

This process makes the yarns smoother and more shiny and at less cost, than the ordinary method.

The common way to straighten and finish this type of yarn is as follows:

The bobbins of thread are whipped and tied in hanks before they are boiled for the To bring yarn to shrink. The reels covered with yarn are then turned into a A container with lukewarm soapy water and then in a container with boiling soapy water submerged. In many cases this immersion happens the first instead of two or three times Time in lukewarm water, the second time in hot water and the third time in boiling water.

The tresses are then pulled off the reels, washed and rolled by means of rollers squeezed out, after which they are hung up to dry in a drying room. After this the yarns have been dried, they are wound on bobbins to be singed. After scorching, they are reeled up and washed again to remove the scorched ones To remove parts.

The yarns are then rinsed in cold water and immersed in boiling water, to cause complete shrinkage and then dried on the reels. Finally the strands are pulled off and tied in bundles.

According to the new process, the yarn as soon as it comes from the spinning machine is produced without subjected to further preparatory work to the operation of scorching and then wound on fresh bobbins.

These bobbins of singed yarn are passed to a washing frame in order to be pre-emptied Running-in of the yarn to remove the scorched parts.

The machine to be used to carry out this procedure is shown in the accompanying drawing shown, partly in elevation and partly on average in Figs. 1 and 2.

The gear train of the machine is shown in Fig. 3, with a part of the machine frame A intended to be broken off.

AA is the frame of the machine that supports the rollers BB . Below these rollers in front of the frame A , a washing container C is attached, which connects the two frame parts.

This container is intended to hold soapy water or other suitable items for cleaning the To take up the liquid to be used by the yarn, which is kept lukewarm by means of a steam pipe will.

From the inner surface of the container C a series of pins protrude sideways, which are intended to receive the bobbins D which carry the singed yarn. The location of these coils is shown at D.

The yarn of the same is passed through the guides EE to the various rollers BB and from there goes to the bobbins F, which sit on the rotatable spindles G. The latter are driven by belts from the pulley H, which sits on the main shaft J. The bobbins F are driven by friction so that they take off the yarn as it is supplied by the rollers BB.

The distribution of the yarn on the bobbins is effected by the rod K rising and lowering. It is provided with a glass shaft on its front edge, in order to prevent the thread from being attacked by the friction.

The bobbins D filled with singed yarn are immersed in the rinsing liquid and the yarn ends in question run individually through the guides up to the rollers.

In this way the thread is freed from almost all the scorched parts.

The rollers squeeze the liquid evenly out of the yarn and deliver a relatively pure material to the bobbins F.

It should be noted here that when the pressure exerted by the nip rollers carefully regulated, the unequal parts in the yarn, which of the unequal

Tension or strength of the threads are almost entirely eliminated. The bobbins with cleaned yarn are removed from the machine, onto the thin ones Rods of a rack pushed up 'and immersed in boiling soapy water, whereby the shrinkage of the yarn is effected for the most part. To allow the soapy water to penetrate the yarn on the bobbins the coils are perforated. The time required to achieve perfect shrinkage of the yarn depends on the strength of the twist and the thickness of the yarn. It takes little experience to find out this time; however, it is beneficial if one tries beforehand with the different qualities of the yarn in order to obtain the Determine the exact duration. 3 to 5 minutes will generally suffice; however require some other types of yarn for a long time. The next operation is to decoil the yarn in order to use it for the rinsing procedure and prepare for cooking. The subsequent treatment of the yarn is similar to that previously used, i.e. H. the reeled ones wet locks are taken out of the boiling water and dried in part by centrifugal force. The reels are then brought into the drying room and the yarn under tension dried, whereupon the strand removed and prepared for sale as usual will. From the above description it can be seen that this is a new method of smoothing and finishing provides significant labor savings for yarn made from wool and hair, by subjecting the yarns to a series of significantly more simplified operations, than usual, and thus a significantly better yarn delivered, as well as the committee is significantly reduced. In order to cut the yarns produced by this process to a certain length a number device is attached to the axis of the reel in such a way that it is indicated to the worker when the reeling has to stop. Patent claim: The method just described, according to which yarns made of wool, hair or a mixture of these materials are treated and what is usually used Process of unhitching, washing, drying, winding etc. before singeing in Elimination comes and a significantly stronger and better manufactured yarn is supplied. 1 sheet of drawings.
