Performance test
Cotton yarn was prepared according to the methods in examples and comparative examples, and the properties of the cotton yarn were examined with reference to the following methods, and the examination results are recorded in table 1.
1. Antibacterial rate: evaluation of antimicrobial Properties of textiles according to GB/T20944.3-2008 part 3: the vibration method is used for testing, staphylococcus aureus and escherichia coli are selected as test strains, and the antibacterial rate is detected when the bacteria are not washed, washed for 10 times, washed for 20 times and washed for 30 times respectively.
2. Fluffiness: the measurement is carried out according to FZ/T50009.4-2019 'hollow polyester staple fiber bulkiness and elasticity test method', a 200mL measuring cylinder and a 3kg weight are adopted, the volume of the fiber in the measuring cylinder when the fiber is not loaded is measured, then the volume of the fiber before and after the loading is measured and calculated, and according to the ratio of B (bulkiness) = (V1/V2) multiplied by 100%, V1 is the volume of the fiber under the action of the load, and V2 is the volume of the fiber after the load is removed.
Table 1 results of performance test of antibacterial fluffy blended cotton yarn
The initial antibacterial rate of the cotton yarn in the embodiment 1 and the embodiment 2 to the escherichia coli reaches more than 90%, after washing, the antibacterial rate is reduced, the first 10 times of reduction is obvious, and the trend of reducing the antibacterial rate is slowed down when the 30 th time is compared with the 20 th time; the same is true of staphylococcus aureus; in addition, the cotton yarn has higher volume recovery after loading.
The initial antibacterial rates of the cotton yarn to staphylococcus aureus and escherichia coli of the example 3 and the example 4 are increased to more than 95% compared with the example 1, the antibacterial rate decrease trend is weakened along with the increase of the washing times, the antibacterial rates are more than 94% after the washing for 30 times, and the antibacterial agent has better antibacterial property and antibacterial durability than the example 1.
In example 5, compared with example 4, the hollow coffee carbon polyester fiber is pretreated by silk fibroin nano silver, and the polyvinyl alcohol aqueous solution and the polyvinyl alcohol dehydrogenase aqueous solution are not used, and the initial antibacterial rate of the blended cotton yarn prepared in example 5 on escherichia coli and staphylococcus aureus is similar to that of example 4, but after 10 times of washing, the antibacterial rate is obviously reduced, which means that the hollow coffee carbon polyester fiber and silk fibroin nano silver are directly mixed and impregnated, so that the initial antibacterial property of the blended cotton yarn can only be improved, and the antibacterial durability of the blended cotton yarn can not be prolonged.
Compared with example 4, example 6 and example 7 not only pretreat the hollow coffee carbon polyester fiber, but also use antibacterial finishing liquid made of modified diatom ooze, pomegranate rind extract and the like, and table 1 shows that the initial antibacterial rate of the blended cotton yarn made of example 6 and example 7 on escherichia coli and staphylococcus aureus reaches 99.99%, and the blended cotton yarn still has higher antibacterial effect after 30 times of washing, and has lasting antibacterial property.
Examples 8-10 differ from example 7 in that rare earth gadolinium nitrate, zinc sulfate and pericarpium Granati extract were not added to the antimicrobial finish, respectively, and the data in table 1 show that the initial antibacterial rate of the blended cotton yarn prepared in examples 8 and 10 is inferior to that in example 7, and the antibacterial rate is reduced with the increase of the washing times.
The cotton fiber in comparative example 1 was not pretreated, and the initial antibacterial rate of the cotton yarn in comparative example 1 was small compared with example 1, and the antibacterial rate was gradually decreased as the number of washing times was increased.
Comparative example 2 and comparative example 3, compared with example 1, the antimicrobial and mildew preventive was not added with hamamelis extract and banana peel extract, respectively, and table 1 shows that the initial antibacterial rate of the cotton yarn prepared in comparative example 2 and comparative example 3 was smaller than that of example 1, the washing times were increased, and the antibacterial rate was reduced.
In comparative example 4, the cotton fibers were not treated with the antibacterial treatment such as graphene oxide, and the initial antibacterial rate of the cotton yarn prepared in comparative example 4 against escherichia coli and staphylococcus aureus was reduced as compared with example 1, and the antibacterial rate was significantly reduced as the number of washing times was increased, which indicates that graphene can improve the initial antibacterial effect of the cotton yarn and extend the antibacterial long-term effect.
Comparative example 5 and comparative example 6 were compared with example 1, the initial antibacterial ratio of the cotton yarn prepared in comparative example 5 and comparative example 6 was smaller than that of example 1, and the antibacterial ratio was gradually decreased with the increase of the washing times, and the bulkiness of the cotton yarn was also decreased.
Comparative example 7 is an antibacterial blended regenerated cotton yarn prepared in the prior art, the initial antibacterial rate is lower than 90%, the antibacterial rate is obviously reduced along with the increase of the washing times, and in addition, the volume of the cotton yarn is only 105ml before no load is applied, the bulkiness is 61.8%, and the bulkiness and the antibacterial property are both lower than those of example 1.
The present embodiment is merely illustrative of the present application and is not intended to be limiting, and those skilled in the art, after having read the present specification, may make modifications to the present embodiment without creative contribution as required, but is protected by patent laws within the scope of the claims of the present application.
