| Abstract: | The heat resistance of the primary monomers of finishes,like atatic polyethylene and polyol fatty acid ester,for polyester industrial yarn were studied.The results showed that pentaerythritol fatty acid ester can be synthesized at 220-240 ℃ using an atactic polyethylene with the relative molecular mass of 1 800-3 000 and the ethylene oxide-and-propylene oxide(EO/PO) mass ratio of 50/50-60/40 and a fatty acid with the carbon distribution of 8-18 as raw materials.The product had superior heat resistance and low volatilization amount,smoke generation and tarring degree at high temperatures.The commercial test indicated that the finishes for polyester industrial yarn exhibited excellent heat resistance and spinnability. |
