Anti static equipment g yo "· Synthe sefaserm atoria 1

For the antistatic treatment of Syirfche fiber material Quarter of ammonium salts are often used. These connections however, often do not have sufficient substantivity towards synthetic fiber material, especially towards Polyamide fiber material, which is why the equipment from aqueous liquor in the drawing process is inadequate Bathroom utilization leads. The anti-static effect is also not always sufficient.

From the published JA-PA 26 523/67 are sulfonate betaines, which contain an alkyl radical with 12-16 carbon atoms, known as an antistatic agent for incorporation into plastics. The antistatic effect of these compounds is but not particularly high. Furthermore, from DT-AS 24 09 412 sulfonate betaines are also known that one of an o ^ / - 01e fin derived hydroxy alkyl residue with 8-18 Have carbon atoms. These compounds have relatively low water solubility and are used only as antistatic agents recommended for incorporation into plastics.

The invention relates to the use of hydroxybetaines general formula _

The olefins used as starting materials are produced by dehydrogenating paraffins or by oligomerizing ethylene. Olefins with an internal double bond are particularly preferred. The individual reaction steps for the production of betaines are known in principle.

The hydroxybetaines have a surprisingly high antistatic effectiveness and are excellent Substantivity for synthetic fiber material. They are in the form of aqueous or aqueous-alcoholic solutions with

The treatment causes electrostatic charges to occur reliably suppressed during processing or use of the fiber materials.
