The invention relates to a temperature-resistant spin finish for Polyesterendlosfäden fine denier, which are subjected to a texturing during subsequent processing. The aim of the invention is to allow proper processing properties of polyester filaments of fine denier during texturing by a temperature-resistant spin finish. The object of the invention is to provide a temperature-resistant spin finish for Polyesterendlosfäden fine denier, which can be textured. According to the invention the object is achieved by a spin finish which is a synergistic mixture of a) an oxyethylated higher aliphatic alcohol, b) an oxyethylated alkylphenol, c) a paraffin oil, d) an aromatic dicarboxylic acid ester and e) a phosphorus salt of an alkylpolyglycol ether, wherein the proportion a) 30 to 55%, b) 10 to 35%, c) 10 to 35%, d) 3 to 15% and e) 2 to 10%. The spin finish is used for the production of polyester textile filaments from polyester filaments. |
