TABLE 4 results of the experiments of the experimental samples 1 to 18 and the comparative samples 1 to 4

As can be seen from Table 4, the smoke points of the experimental samples 1 to 18 were 210 ℃ and 253 ℃, the volatilization losses were 0.7 to 2.2%, and the specific resistivities were 2.69X 10^-9Ω·cm-3.43×10^-9Omega cm, softness rating of 9.0-9.8; the smoke point of the comparative samples 1 to 4 was 115 ℃ and 181 ℃, the volatilization loss was 2.8 to 5.1%, and the specific resistivity was 3.68X 10^-9Ω·cm-4.15×10^-9Omega cm, softness evaluation of 8.1-8.9; compared with the comparative samples 1-6, the experimental samples 1-18 have the advantages of high smoke point, less volatilization loss and better softness, which shows that the oil agent of the experimental samples 1-18 has better heat resistance and antistatic property, and endows the prepared polyester fiber with better softness.

It can be seen from comparison of experimental sample 1 and comparative samples 1 to 3 that the heat resistance of the oil composition can be enhanced by adding the pyrocarbon mother extract and the sucrose polyester. Probably because of the higher stability of sucrose polyester, the better properties are still maintained after high temperature treatment. The pyrocarbon mother extract has high antioxidant activity, and after the pyrocarbon mother extract and the pyrocarbon mother extract are matched with each other, the lubricity of the oil agent composition is enhanced, and meanwhile, the oil agent composition is endowed with good heat resistance.

Comparing the experimental sample 1 with the experimental samples 3-4, it can be seen that the polyester POY is effectively wetted after the wetting agent is selected, so that the active ingredients such as the Chinese knotweed extract, the sucrose polyester and the like are immersed in the polyester POY, volatilization of the oil composition on the polyester POY is reduced, and the heat resistance of the oil composition is improved; comparing the experimental sample 1 with the experimental samples 5-6, it can be seen that the specific components of the antistatic agent are preferably selected to improve the interface performance of the oil composition, thereby further improving the heat resistance of the oil composition; comparing the experimental sample 1 with the experimental samples 7-8, it can be seen that after the heat stabilizer is added, the heat resistance of the oil composition is improved, and after the rare earth citrate and the zinc stearate are added, the stability of the polyester POY is improved while the polyester POY is lubricated; comparing the experimental sample 8 with the experimental samples 9-10, it can be seen that the components and weight ratio of the heat stabilizer are preferably selected, the citric acid rare earth and the zinc stearate are combined to form a composite system, and the two have better synergistic effect, so that the heat resistance of the oil composition is further enhanced.

Comparing the experimental sample 1 and the experimental samples 11 to 12, it can be seen that the heat resistance of the oil composition is enhanced and the antistatic property is improved after the additive is added, and the softness of the obtained polyester fiber is improved. Probably because the talcum powder and the nano carbon black in the additive have better heat resistance on one hand and antistatic property on the other hand. In addition, the nano carbon black in the additive effectively permeates into the polyester POY at high temperature, so that the toughness of the polyester POY is improved; comparing the experimental sample 1 with the experimental samples 13-14, it can be seen that after the elm extract is added, the elm extract and the pyrocarbon mother extract are cooperated with each other to further protect the oil, thereby effectively enhancing the heat resistance of the chemical fiber oil composition.

Comparing the experimental sample 1 and the experimental samples 15-16, it can be seen that the smoke point of the oil composition is greatly improved and the volatilization loss is less after the heat stabilizer, the additive and the elm fungus extract are added, which indicates that the heat stability of the oil composition is enhanced.

Comparing the experimental sample 1 and the experimental samples 17-18, it can be seen that when the specific components of the wetting agent and the antistatic agent are preferably selected, and the heat stabilizer, the additive and the elm fungus extract are added, the heat resistance of the oil agent is enhanced, and the antistatic performance and the softness are greatly improved.
