The antibacterial property test is carried out according to textile industry standard FZ/T01021-92 fabric antibacterial property test method, and the antibacterial property test result of the mattress is shown in table 1.
Table 1 influence of pinus koraiensis antimicrobial microcapsule dosage on antimicrobial properties of pinus koraiensis microcapsule mattress
As can be seen from Table 1, even if the dosage of the Korean pine microcapsule is only 10g/L, the bacteriostasis rate is over 60 percent, thereby showing that the bacteriostasis effect of the Korean pine microcapsule finishing is obvious. Moreover, with the increase of the using amount of the Korean pine essential oil microcapsules, the antibacterial rate of the finished mattress gradually rises, when the using amount of the microcapsules is 30g/L, the antibacterial rate of escherichia coli reaches 93.25%, and from the data in the table, the antibacterial rate is increased by 30% compared with that when the using amount is 10g/L although the using amount is only increased by 20g, so that the conclusion can be drawn that when the using amount of the microcapsules is 30g/L, the antibacterial effect is remarkably improved; along with the increase of the dosage of the microcapsule, the improvement of the bacteriostatic effect is relatively slow and unchanged. The antibacterial rate to staphylococcus aureus reaches 94.37% when the microcapsule dosage is 30g/L, the antibacterial effect is obviously improved under the condition of the dosage, and the antibacterial rate is slowly increased along with the increase of the dosage when the microcapsule dosage is more than 30 g/L. From the above, when the dosage of the microcapsule is 30g/L, the mattress can achieve good antibacterial effect, when the dosage of the microcapsule is continuously increased,
2. testing for odor elimination: the odor eliminating test is carried out according to GB T33610.2-2017 part 2 inspection tube method for measuring the odor eliminating performance of textiles; its purpose is in order to verify the flavor eliminating effect of mattress.
The sample (specification 100 cm)2) Placing into a sampling bag, injecting 3L of gas containing odor components to reach a specified initial concentration, and measuring component concentration with a detection tube after 2 h. The results of the odor removal experiments on the fabrics are shown in table 2.
TABLE 2 influence of washed Korean pine antibacterial microcapsule on odor eliminating performance of mattress
The Korean pine microcapsule mattress prepared by the invention has stable peculiar smell eliminating performance and can not be lost due to washing, and as can be seen from the table 2, the elimination rate of peculiar smell gas is not obviously reduced before and after 10 times of washing, so that the invention shows that after the mattress is finished by utilizing the microcapsule, even if the mattress is washed for a certain time, the adsorption and elimination capacity of the microcapsule on the peculiar smell is not obviously lost, and the washability of the mattress is very good.
3. And (3) testing the anti-mite performance: the anti-mite performance test is carried out according to GB/T24253-2009 evaluation of anti-mite performance of textiles, and the aim is to verify the anti-mite effect of the mattress.
The test sample and the control sample were placed in a petri dish and simultaneously contacted with mites under prescribed conditions. After a certain period of culture, counting the number of mites living in the sample culture dish and the control sample culture dish, and calculating the mite avoidance rate according to the adopted sample method. Tests show that the mite avoidance rate of the Korean pine microcapsule mattress is more than 80%, and the mattress has a strong mite prevention effect.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention are equivalent to or changed within the technical scope of the present invention.
