Claims
- 1. A lubricating agent for processing yarns, said lubricating agent containing polyalkylene ether polycarbonate compounds shown by the general formula (I) below: ##STR11## where R.sub.1 is an organic residue obtainable by removing an active hydrogen group from an organic compound; R.sub.2 to R.sub.4 may be similar or different, each being hydrogen, methyl group or ethyl group; R.sub.5 is hydrogen, alkyl group with 1 to 3 carbon atoms, alkanoyl group with 2 to 18 carbon atoms or trialkylsilyl group with 1 to 3 carbon atoms; X is --O--, --S--, --COO--, --N< or --CON<; l is an integer equal to or larger than 1; m is 0 or an integer equal to or larger than 1; and n is an integer in the range of 1 to 8 such that the product ln is equal to or greater than 2.
- 2. The lubricating agent of claim 1 wherein said organic compound is monohydric alcohol with 1 to 30 carbon atoms, polyhydric alcohol with 1 to 30 carbon atoms, phenol with 1 to 30 carbon atoms or polyglycolether obtainable therefrom by addition of alkylene oxide with 2 to 4 carbon atoms.
- 3. A method of processing thermoplastic synthetic yarns, said method comprising the step of applying a lubricating agent at a rate of 0.1 to 3.0 weight .delta. with respect to said yarns in a process prior to the completion of drawing and orientation of said yarns in the production process thereof, said lubricating agent containing a polyalkylene ether polycarbonate compound shown by the formula (I) below: ##STR12## where R.sub.1 is an organic residue obtainable by removing an active hydrogen group from an organic compound; R.sub.2 to R.sub.4 may be similar or different, each being hydrogen, methyl group or ethyl group; R.sub.5 is hydrogen, alkyl group with 1 to 3 carbon atoms, alkanoyl group with 2 to 18 carbon atoms or trialkylsilyl group with 1 to 3 carbon atoms; X is --O--, --S--, --COO--, --N< or --CON<; l is an integer equal to or larger than 1; m is 0 or an integer equal to or larger than 1; and n is an integer in the range of 1 to 8 such that the product ln is equal to or greater than 2.
- 4. The method of claim 3 wherein said organic compound is monohydric alcohol with 1 to 30 carbon atoms, polyhydric alcohol with 1 to 30 carbon atoms, phenol with 1 to 30 carbon atoms or polyglycolether obtainable therefrom by addition of alkylene oxide with 2 to 4 carbon atoms.
- 5. The lubricating agent of claim 1 wherein l is equal to or larger than 2.
- 6. The method of claim 3 wherein l is equal to or larger than 2.
