Definitions

• thermostable antistatic agents for example a quaternization product of the reaction product of diethylaminoethanol with 10 mol of ethylene oxide and 20 mol of propylene oxide.
• the thermal test (230-235 ° C / 24 hours) indeed shows that these products form only a few residues, but even the remaining residues are too high and can contaminate the heater, especially as the possibly solid residues through reaction with thread guide elements cause additional thread breaks can.
• the amine oxides described in DE-PS 23 26 966 have proven themselves well in preparation formulations, especially in combination with low-volatility lubricants, they give the threads good antistatic properties and are to be regarded as thermostable. However, they often have too high a volatility in short-term heating processes, so that when these amine oxides are used alone, the problem of vaporization from the thread can occur too quickly.
• the invention thus relates to a fiber preparation agent which contains an amine oxide of the formula where R 1 is C 4 -C 22 alkyl or C 4 -C 22 alkenyl, preferably C 10 -C 16 alkyl, R 2 is hydrogen and / or methyl, where hydrogen and methyl can alternate, R 3 and R 4 C 1 -C 4 alkyl and X is a number from 1 to 20, preferably 3 to 10.
• amine oxides are known from US-A 3 371 180, NL-A 70 15 335 and JA-A 72 13 016. They are obtained by known methods by using alkoxylated long-chain alcohols of the formula chlorinated, for example with thionyl chloride. The chlorides obtained are then with secondary amines of the formula implemented and the reaction products then oxidized with H 2 O 2 .
• Preferred alkoxylated long-chain alcohols are preferably coconut fatty alcohol with 5 units of ethylene oxide, oleyl alcohol with 7 units of ethylene oxide, but also the following compounds: and pentaerythritol ⁇ (EO) 5.
• chain-pure alkyl compounds instead of the chain-pure alkyl compounds, it is of course also possible in any case to use compounds whose alkyl groups represent technical sections, the average number of carbon atoms corresponding to or coming close to the abovementioned alkyl radicals.
• the alkyl residues accumulating from natural long-chain fatty acids are particularly preferred since the corresponding alcohols with one or two long-chain alkyl residues are commercially available and the amine oxides are thus easily accessible.
• the numerical value X is generally an average value, since technical oxyalkylation generally results in product mixtures. This also applies to the oxyethylates listed here - for the sake of simplicity as uniformly formulated. '
• amine oxides described above are used as antistatic agents in conventional preparation agents.
• these preparation agents usually consist of approx. 20 to 60% by weight of a lubricant such as, for example, ester oils, mineral oils, end-capped oxethylates, propylene-ethylene oxide copolymers, 0 - 50% by weight emulsifier, for example fatty alcohol oxyethylates, 0 - 30% by weight % other antistakics, for example P 2 O 5 esters of fatty alcohols and 1-50% by weight of the amine oxides according to the invention.

• the amine oxides according to the invention can be used alone or in combination with thread-locking agents (oxyethylated castor oils, sarcosides, FOCl 3 esters) and sliding components (phosphoric acid esters).
• thread-locking agents oxyethylated castor oils, sarcosides, FOCl 3 esters
• sliding components phosphoric acid esters
• the amine oxides show a high antistatic effect even in relatively low doses.
• the required quantities fluctuate depending on the type and quantity of the other components (oil, emulsifier) and can be easily determined by simple preliminary tests.
• the favorable properties of the amine oxides as preparation agents are particularly evident on synthetic fibers such as those made of polyester, polyamide 6, polyamide 6,6, polyacrylonitrile or polyolefin.
• a polyester thread dtex 300 f 32 matt is at 2800m / min. spun out, prepared with 12% preparations and on a stretch texturing machine using the friction method on dtex 167 at 800 m / min. stretch textured.
