Effect Verification

[0107] The aromatic PBT false eyelashes prepared by Embodiments 1, 2, 3 and Comparison examples 1, 2, 3 were selected as samples. 1 g of each sample was put into a round-bottom flask filled with anhydrous ethanol solution to reflux at 75 C. for 1 h. Then the sample was filtered, and an absorbance of a filtrate was measured. Then an essence concentration corresponding to the absorbance was found in the standard working curve, thereby obtaining an essence content of the aromatic PBT false eyelashes. The test results are shown in Table 1. The evaluation results of aroma retention of treated PBT false eyelashes are shown in Table 2.

[0108] It can be seen from Table 1 and Table 2 that the aromatic chemical fiber false eyelashes in Embodiment 1-3 have excellent aromatic effect, long fragrance holding time and long service life after finishing by the microcapsule containing niobate core material. It can be obviously seen that an introduction of the niobate can more effectively protect volatile and easily denatured substances in the essential oil from an influence of the external environment, promote the slow release of the aromatic microcapsule, and further increase a service life of the aromatic chemical fiber false eyelashes, which can be used for up to 120 days.
