2. and (3) mite-repelling rate: detection is carried out according to FZ/T62012-2009 mite-proof bedding.
TABLE 3 persistent test results of antibacterial and acarid-expelling of quilt cover fabric

Comparative example 1 since the highly effective anti-mite antibacterial agent was not added when preparing the quilt cover fabric, the difference between the antibacterial rate and the anti-mite rate was large before and after washing, and the durability of antibacterial and anti-mite was reduced in the quilt cover fabric prepared in comparative example 1.
In comparative example 2, as the modified anion powder and the modified montmorillonite are not added in the high-efficiency anti-mite antibacterial agent in the quilt cover, the antibacterial rates of escherichia coli, staphylococcus aureus and candida albicans are respectively 78.6%, 74.5% and 66.5%, compared with examples 1-5, the antibacterial rates are larger, and after 20 times of washing, the inhibition effect on various bacteria is reduced, and the mite-repellent rate is reduced, which indicates that the modified anion and the modified montmorillonite can increase the antibacterial and mite-repellent effect of the quilt cover fabric and can increase the durability of the antibacterial and mite-repellent effect.
Comparative example 3 since the lemongrass essential oil and passion fruit juice extract are not added to the high-efficiency anti-mite antibacterial agent in the quilt cover, the quilt cover fabric prepared in the comparative example 3 has a low antibacterial rate to escherichia coli, staphylococcus aureus and candida albicans, and the antibacterial rate is remarkably reduced after washing, which indicates that the durability of the antibacterial rate and the mite-repellent rate is poor.
Comparative example 4 because bamboo charcoal viscose fiber and medical stone fiber are not added in the quilt cover raw material, the difference between the antibacterial rate and the mite-repellent rate of the quilt cover fabric prepared in comparative example 4 to escherichia coli, staphylococcus aureus and candida albicans is large before and after washing, which indicates that the antibacterial rate and the mite-repellent rate prepared in comparative example 4 are poor in durability.
Comparative example 5 because rosewood essential oil and xanthan gum are not added in the quilt cover raw material, the antibacterial rate and the mite-repellent rate of the quilt cover fabric prepared in comparative example 5 are greatly different before and after washing, which indicates that the antibacterial property and the durability of the mite-repellent effect are poor.
Comparative example 6 since the silk fiber, the medical stone fiber and the bamboo charcoal viscose fiber were not fermented in the folium artemisiae argyi solution in the preparation of the quilt cover fabric, the quilt cover fabric prepared in comparative example 6 has a small antibacterial rate and a small mite-repellent rate, and a large difference before and after washing, compared with examples 1 to 5, which indicates that the quilt cover fabric prepared in comparative example 6 has poor antibacterial and mite-repellent durability.
Comparative example 8 the silk fabric prepared by the prior art is used to prepare the quilt cover fabric, and the detection results show that the antibacterial rate of the silk fabric to escherichia coli, staphylococcus aureus and candida albicans is lower than that of the quilt cover fabrics prepared in the embodiments 1-5 of the present invention, the mite-repellent rate is lower, after 20 times of washing, the antibacterial rate and the mite-repellent rate are obviously reduced, and the antibacterial and mite-repellent durability is lower than that of the quilt cover fabrics prepared in the embodiments 1-5 of the present invention.
Secondly, the antibacterial and mite-repellent durability of the filler is detected: the filling was prepared according to the methods of examples 1 to 5, comparative examples 1 to 3, comparative example 7 and comparative example 9, the cover fabrics prepared in each example and each comparative example were placed in an environment of 20 to 25 ℃ and a relative humidity of 65 to 80%, and the antibacterial rate and the acarid-repelling rate of the cover fabrics were measured according to the following methods, the cover fabrics prepared in each example and each comparative example were washed according to the method of GB/T8629-2017 "home washing and drying procedure for textile test", the washing degree was 4N, the washing was performed 20 times, the drying was performed 1 time, the cover fabrics prepared in each example and each comparative example were placed in an environment of 20 to 25 ℃ and a relative humidity of 65 to 80% for a certain period of time, the antibacterial rate and the acarid-repelling rate of the cover fabrics after washing were measured, and the measurement results were recorded in table 4:
1. the antibacterial rate is as follows: according to GB/T20944.3-2008, evaluation of antibacterial performance of textiles part 3: detecting by an oscillation method;
2. and (3) mite-repelling rate: detection is carried out according to FZ/T62012-2009 mite-proof bedding.
TABLE 4 antibacterial and mite-repelling persistence test results of the fillers
As can be seen from the data in table 4, before the fillers prepared by the methods in examples 1 to 5 are washed, the antibacterial rates of escherichia coli, staphylococcus aureus and candida albicans are all over 90%, the fillers have good antibacterial effects, the mite-repelling rate is 96.7-97.4%, the mites are high and good in mite-repelling effect, and after the fillers are washed for 20 times, the fillers are still placed in an environment where bacteria and mites are easy to breed, and the antibacterial rates and the mite-repelling rates are good, so that the fillers prepared by the method have good antibacterial and mite-repelling persistence.
Comparative example 1 because the high-efficiency anti-mite antibacterial agent is not added when the filler is prepared, the antibacterial rate and the mite-repelling rate of the filler prepared by the comparative example 1 before washing are low, and after washing, the antibacterial rate and the mite-repelling rate are obviously reduced, which shows that the high-efficiency anti-mite antibacterial agent not only can enable the filler to have high antibacterial and mite-killing effects, but also has strong adhesion of the high-efficiency anti-mite antibacterial agent, and enables the antibacterial and mite-killing durability to be good.
Comparative example 2 because the modified anion powder and the modified montmorillonite are not added in the high-efficiency mite-preventing antibacterial agent in the filler, the antibacterial rate of the filler prepared by the comparative example 2 to escherichia coli is only 79.8% before washing, and is 68.4% after washing, the initial antibacterial rate is low, the loss of the antibacterial rate after washing is serious, and the mite-repelling rate is also the same, so that the modified anion powder and the modified montmorillonite can improve the antibacterial and mite-killing effect of the filler and prolong the antibacterial and mite-killing time.
Comparative example 3 because the lemongrass essential oil and passion fruit juice extract are not added in the high-efficiency anti-mite antibacterial agent for the filler, data in table 4 show that the antibacterial rate of the filler prepared in comparative example 3 to bacteria is obviously reduced before and after washing, and the mite-repelling rate is lost, which shows that the lemongrass essential oil and passion fruit juice extract can improve the antibacterial and mite-killing effect of the filler and enable the filler to have better antibacterial and mite-killing durability.
Comparative example 4 because the bamboo charcoal viscose fiber and the medical stone fiber are not added in the filler, the antibacterial rate and the mite removing rate of the filler prepared in comparative example 4 are small compared with those of examples 1-5 before washing, and the antibacterial rate and the mite removing rate are seriously reduced compared with those before washing after washing, which indicates that the durability of the antibacterial and the mite removing is poor.
Comparative example 7 because tea tree oil, graphene and nano zirconia powder are not added in the raw materials of the filler, the antibacterial rate and the mite removing rate of the filler prepared in comparative example 7 are reduced and the durability is deteriorated through comparison.
Comparative example 9 the quilt core prepared in the prior art was used as a filling, and the antibacterial rate and the acarid-repelling rate were greatly different from those of examples 1 to 5, and the durability was inferior to that of the filling prepared in examples 1 to 5 of the present invention.
