The invention relates to the separation of mixtures of ϊβχΐϋ fibers by means of an electrostatic arrangement. Such mixtures are obtained ζ · Β _β when textile fibers for the

further use by daa known under the name Lumpenzer Process uiahl or rag tearing process / are recovered in which used textiles, which consist essentially of wool, are mechanically shredded into a mass of loose fibers, which for are suitable for re-application by the textile industry. If the original textiles are made of other fibers than full fibers contained, as this is now generally the pail, the recovered mass also consists of a mixture of wool fibers with a greater or lesser proportion of non-volatile pasers, which can be of different types.

The presence of these pa3ers limits the value of the recovered I.Iateriala voa textile standpoint from a, since with the renewed Manufacturing processes such as spinning, weaving, dyeing and appre

animals cause trouble.

In accordance with the invention, a! 'race of a mixture of i'eatilgut fibers, and in particular a mixture of solid fibers and not woolly fibers.

The invention relates to a method for separating a mixture of textile fibers, which is characterized by the fact that the fibers dispersed in a stream of air and at the same time this or in Then at least some of the fibers are electrostatically charged and the different lines of the mixture in one separate electrostatic field,

The invention also relates to a device for air traffic control this method, which is characterized in that an arrangement for jiopergieren the pasers in a l'if tstroui, a Arrangement for the simultaneous or subsequent electrostatic charging of at least one of the fibers and one Arrangement for the separation of the different strands of the mixture is provided in an electrostatic PeId.

The different paseins in the mixture can have opposite charges Sign or the same sign and still some lines can remain uncharged. Me Different decay rates of the same charges on different strands can be used to separate the louvers.

The electrostatic separation of a paser or particulate Mixture takes advantage of the fact that an electrically charged particle, when placed in an electrostatic field, tends to; ο along the lines of force of the field in the direction of the face

to move the electrode, which carries a charge with opposite rolling

° rity with respect to the charge carried by the particle

^. Finally the particle reaches the ülektrodo and is on the- • same dejected. Thus it becomes a mixture of particles

Mineral (hydrocarbon ) oils, vegetable gels such as olive oil and silicone oils have been used successfully.

It is further found that the presence of an antistatic agent, either in the presence or in the absence of oil, teases the efficiency of the separation process. Up to 0.5% by weight, preferably 0.05 to 0.2% by weight, ύ> · ν antistatic kittols can be used. Suitable types of antistatic agents include the non-ionic ethylene oxide conuenoates, which are known commercially under the drawings Lubrol W and Oirrasol Lj F 200. The antistatic agent can be sprayed on in an aqueous solution, if in the presence of one OeIs are being worked on, a Gemish with the uel can be used.

The relative humidity of the surrounding atmosphere and the Moisture content of the fibers appear to be of major importance in controlling the efficiency of the separation to play.
