A kind of polyester fdy oil agent and preparation method thereof

Abstract

The invention discloses a polyester FDY oil agent and a preparation method thereof. The existing oil has poor heat resistance, serious volatilization, and heavy smoke in the workshop, which seriously affects the working environment and health of workers; the coking phenomenon of the oil is relatively serious, resulting in wool and broken ends. The components and weight percentages of the present invention are: high temperature resistant smoothing agent 55-65%, environmental protection emulsifier 15-25%, sizing agent 3-10%, composite antistatic agent 5-8%, and the rest are additives, The high temperature resistant smoothing agent contains special polyether. The invention has good heat resistance, is suitable for high-speed spinning process of various specifications including coarse denier polyester fibers, does not emit smoke, and does not coke on hot rollers.

Description

technical field

[0001] The invention relates to an auxiliary agent used in polyester filament processing, in particular to a polyester FDY oil agent and a preparation method thereof. Background technique

[0002] Spinning oil must be used in polyester production. Polyester FDY oil is a necessary auxiliary in the one-step spinning process of polyester spinning. processing requirements. At present, most of the polyester FDY oils in my country rely on imports, but the price is relatively high, causing a certain cost burden on the chemical fiber industry with poor profitability. Although the domestic FDY oil has been successfully developed, compared with the imported oil, it has the disadvantages of unstable quality and poor post-processing performance. The current market share of domestic oil agents is less than 20%, and there are some obvious deficiencies in the quality of oil agents. Firstly, the heat resistance of the oil agent is poor. When the medium-coarse denier yarn ...
