Performance testing

And (3) putting 14 treated completely identical fabrics into the samples of the examples 1-4 and the comparative examples 1-10, soaking, taking out after 10-20 minutes, and then air-drying or drying at a temperature below 80 ℃ to obtain 14 fabrics with bacteriostasis and wear resistance. The test results were as follows:

the test method comprises the following steps:

carrying out an antibacterial test on 14 pieces of bacteriostatic and wear-resistant fabric. The method needs to drop or spread the bacterial liquid on a sample to culture for a certain time (usually 24 hours), the nutrition temperature, humidity, pH, time and the like need to be strictly controlled in the process, and finally the antibiotic rate is calculated by using movable plate counting. The bacteria used in the experiment are staphylococcus aureus.

Secondly, carrying out abrasion resistance test on 14 pieces of antibacterial and abrasion-resistant fabric by using a Martindale tester. Placing a test sample in each clamp ring with the test surface facing outward; clamping the test sample to prevent the test sample from sagging, wrinkling and distorting; placing a heavy hammer on the test sample, smoothing wrinkles, and removing the heavy hammer; correctly placing the test sample in a test fixture to ensure that the test can normally run; and (3) loading force on each test head to ensure that the test sample and the wear-resistant sample are loaded with force values according to requirements. Data were recorded and compared.

The test results are shown in table 1.

TABLE 1

Fig. 1 is photographs showing results of the antibacterial tests of example 3 and comparative example 7, wherein (a) is a photograph showing a result of the antibacterial test of example 3, and (b) is a photograph showing a result of the antibacterial test of comparative example 7.

As can be seen from the antibacterial test results shown in fig. 1 and the data in table 1, examples 1 to 4 all include three components of the graywater of rice straw, the rice washing water and the allicin, and have better antibacterial performance, and especially, the optimal antibacterial effect is achieved by the mixture ratio of the graywater of rice straw, the rice washing water and the allicin in example 3;

in comparative examples 1 to 3, one component of the grey water of rice straw, the rice washing water and the allicin is respectively deleted, and the antibacterial performance is reduced to some extent; in comparative examples 4-6, two components of the grey water of rice straw, the rice washing water and the allicin are respectively deleted, the antibacterial performance is obviously reduced, and the reduction range of the performance is larger than the sum of the reduction ranges of the performance of the components which are deleted; comparative example 7, in which all components of graywater of rice straw, rice washing water and allicin were deleted, had the worst antibacterial effect; therefore, the three components of the straw ash water, the rice washing water and the allicin produce a synergistic effect.

As can be seen from the data in table 1, in examples 1 to 4, the wear-resistant rubber composition comprises two components, namely the nano-sized kaolin and the high wear-resistant carbon black, and has a good wear-resistant property, and particularly, the best wear-resistant effect is achieved under the condition of the proportion of the nano-sized kaolin to the high wear-resistant carbon black in example 3;

one component is lost in comparative examples 8-9, so that the wear resistance is reduced; the two components are deleted in the comparative example 10, the wear resistance is obviously reduced, and the reduction range of the performance is larger than the sum of the reduction ranges of the performance of the components which are deleted; therefore, the nano kaolin and the high wear-resistant carbon black have synergistic effect.
