Abstract
Abstract Amine oxides of the formula R 1 R 2 R 3 N→O, in which R 1 is medium- to long-chain alkyl, R 2 is short- to long-chain alkyl or polyethyleneglycol, R 3 is short chain alkyl or polyethyleneglycol, with the provisos that the polyethylene glycol groups together have not more than 10 glycol units, and that R 3 is polyglycol if R 2 is medium- to long-chain alkyl, are useful as antistatic agents in lubricating agents for synthetic fibers. The amine oxides are distinguished by a good thermal stability, are low-volatile, non-corrosive, compatible with usual lubricating agents and soluble in aqueous and oily lubricating compositions.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
128 words
A fiber-lubricating composition consisting essentially of a paraffin oil or silicone oil, an emulsifier and an amine oxide of the formula in which R 1 is alkyl of 5 to 22 carbon atoms, R 2 is alkyl of 1 to 22 carbon atoms or a polyglycol group of the formula --(CH.sub.2 CH.sub.2 O).sub.n --H in which n is a number of 1 to 5, and R 3 is alkyl of 1 to 5 carbon atoms, or a polyglycol group of the formula --(CH.sub.2 CH.sub.2 O).sub.m --H in which m is a number of 1 to 10, the sum of n and m being not more than 10, with the proviso that R 3 is said polyglycol group if R 2 is alkyl of more than 5 carbon atoms.
