Description

Process for the production of yarns from gluten-containing vegetable fibers The invention relates to a new process for the production of yarns from adhesive-containing yarns Vegetable fibers, e.g. B. Flax.

So far, yarns made from plant fibers, especially linen, have mostly been used produced on wing spinning machines, however. In no way particularly economical work. The FIVigelspinnmasclü, nen that for over too years for the production of Flax yarns have been used - and are still being used> work uneconomically, because they not only consume a lot of power, but also only one. low Delivery of the individual spindles can be achieved. Namely, there are wing spinning machines relatively expensive disc bobbins _ used which only have a small amount of yarn to have. Accordingly, it is the cost of servicing due to the frequent and cumbersome time-consuming removal of the full bobbins is relatively high.

It has also been suggested for fine to very fine flax yarns to use the ring spinning machine for wet spinning.

However, the following difficulties have arisen: Have attempts shown that when spinning flax; on a ring spinning machine, on the rotor ring a crust settles, which hampers and brakes the runner in such a way that a large number of thread breaks occurs. This crust formation can be explained by the fact that the Flax fiber contains sticky pectins that are released when the roving is passed through the hot water bath, digested and dissolved. As long as the ring spinning machine is in operation, these p @ ectin substances arrive in a sufficiently dilute aqueous solution to the rotor ring so that no difficulties arise. When the machine is at a standstill, so especially overnight, but now this watery solution dries on the ring, and the sticky pectins harden on the ring to form a crust, so that the Restart of the machine, the runners on the ring are severely slowed down by the crust and thread breaks occur constantly. This crust is difficult to remove and even pouring hot water over it takes some time to loosen the crust.

. An attempt has now been made, by choosing a different material for : the ring traveler to prevent the Arisietz @ en of the sticky substances. The attempts Replace steel rings with barrel rings made of porcelain or highly polished glass, but have in consideration of the manufacturing difficulties and the costs to none Success led.

A particularly simple and effective solution: the task at hand has now been found according to the invention in that at the 2 new ones Process the rotor ring is constantly covered with a film of oil, which the pectin substances Repels containing water and: a setting and hardening of these substances on the ring prevented. This is achieved by the fact that ring spinning machines run on the new V with self-writing #? renden rotor rings are used. Self-lubricating ones are advantageous Rings are used in which the wick extends over the entire inner circumference of the ring extends so that the entire running surface of the ring evenly covered with an oil film is covered.

With the new process - as before with wet ring spinning machines - the roving is passed through a hot water bath before it enters the drafting system. From the drafting system, the yarn runs in a known manner through an eyelet and the ring traveler to the spinning bobbin.

It has also been shown that ring spinning machines are used with self-lubricating rotor rings are also suitable for spinning coarse and Medium-fine flax yarns well suited for the wing spinning machines used so far became. For such coarse and medium-fine yarns, of course, heavy ones are used Runner required at high runner speeds. These heavy runners produce again a high contact pressure, so that the lubrication is also in this respect the rotor rings has a beneficial effect.

The ring spinning machines offer on the other hand to the The wing spinning machines have the following advantages the multiple of the yarn content of a winged bobbin (disc bobbin). the When using a ring spinning machine, the bobbin winder can produce a considerably larger Use number of winding units, so that the operating costs for the same performance of the machine can be significantly reduced: The removal of the ring spinning bobbins is otherwise Much easier and quicker to do than removing the Disc coils. with wing spinning machines.
