PURPOSE:To modify the surface of polyester fibers and obtain the titled fibers having particularly improved adhesive property to rubber, by applying a reactive treating agent and a spinning oil to the polyester fibers during the spinning thereof. CONSTITUTION:In spinning polyester shynthetic fibers, e.g. polyethylene terephthalate fibers, (A) a reactive treating agent, e.g. glycerol diglycidyl ether, and a spinning oil constituted of (A) an aliphatic lubricant and (B) an aromatic lubricant at a weight ration expressed by formulasIand II in the total nonaqueous component are applied to the polyester fibers and give the aimed fibers having improved adhesive property to rubber. A mineral oil, hydrocarbon, e.g. polybutene, or an ester of a higher monohydric alcohol with a higher fatty acid, e.g. butyl stearate, is cited as the component (A), and a higher alcoholic ester of an aromatic carboxylic acid, e.g. phthalic acid, is cited as the component (B). |
