Problems solved by technology

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 domestic FDY oils have been successfully developed, compared with imported oils, they have 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 above 150 denier is processed and the temperature of the second hot roller exceeds 130°C, the oil agent volatilizes seriously, and the smoke in the workshop is large, which seriously affects the working environment and health of workers. Another manifestation of poor heat resistance is that the coking phenomenon of the oil agent is relatively serious. If the continuous use time does not exceed one month, coking will appear on the hot roller, resulting in wool and broken ends
The second disadvantage is that the antistatic property of the oil is not comprehensive. Since domestic oils currently use phosphoric acid esters as antistatic agents, this can only ensure that the oil has good antistatic properties at higher humidity. In the case of antistatic, the antistatic effect is greatly reduced, which leads to the phenomenon of winding and broken ends due to poor antistatic performance in dry seasons or in northern regions.
The third shortcoming is poor stability of the oil agent, which is prone to corruption, which has a great impact on chemical fiber production. The light ones block the pipeline, resulting in uneven oiling, causing wool and broken ends, and severe cases stop production for repairs.
The fourth shortcoming is that the emulsifiers in the FDY oils on the market now contain APEO (alkylphenol polyoxyethylene ether) components, and APEO is an environmental hormone substance, which belongs to the example of Oeko Tex 100 restricted range, which not only It will cause difficulties for the export of products of downstream printing and dyeing enterprises, and will cause environmental pollution and ecological hazards

Abstract

The invention discloses a polyester FDY oil agent and a preparation method thereof. The heat resistance of the existing oil agent is poor with serious volatilization, which results in heavy smog in the workshop and seriously affects the working environment and the body health of the workers; also the oil agent has serious coking phenomena and causes yarn waste and broken ends. The ingredients of the invention and the weight percentages are as follows: 55-65% of high-temperature smoothing agent, 15-25% environment-friendly emulsifying agent, 3-10% binder, 5-8% compound anti-static agent and the rest is additive; and the high-temperature smoothing agent contains special polyether. The invention has good heat resistance and is suitable for the high-speed spinning technique of various polyester fibers (including the high denier); and the oil agent provided by the invention does not generate smoke and does not coke on the hot roll.
