In 1884, German obstetrician Crede dropped 1% silver nitrate solution into eyes of newborn infants to prevent conjunctivitis of newborn infants, and the blindness rate of infants was reduced from 10% to 0.2%. In 1893, tests show that silver has a killing effect on microorganisms such as bacteria, and the silver has a wider medical effect until today. 0.5% silver nitrate is a standard solution for treating burns and wounds; the silver nitrate with the concentration of 10-20% can be applied to treat the uterine erosion. Researches show that the silver has strong killing effect on various pathogenic bacteria such as escherichia coli, staphylococcus aureus and the like, the required concentration is extremely low, and the general dosage is 10^-6And (mass fraction) sterilizing. In terms of safety, silver is one of tissue components in a human body, cells treated by silver ions with very low concentration have no obvious changes of cell aggregation, cell deformation, cell lysis, pH value and the like, and a small amount of silver ions have no obvious harm to the human body. Therefore, the silver-based antibacterial agent is used for improving the antibacterial function of the textile and has sufficient safety.

The silver antibacterial agent has many advantages as an inorganic antibacterial agent, but the silver antibacterial agent has unstable property, nano silver is easy to agglomerate and discolor, silver ions are easy to be converted into brown silver oxide or black simple substance silver through ultraviolet light catalytic reduction, and the appearance of the product and the antibacterial performance are influenced. The composite antibacterial agent is a development direction of antibacterial materials, and many researches prove that the composite antibacterial agent has a better antibacterial effect than that of a single metal ion.

Effect test

1. Bacteriostatic and bactericidal performance test of detergent

The following are selective additions of antimicrobial substances to the base formulation, the added antimicrobial substances being listed in tables 3-5, respectively.

Table 3, this table lists several groups of silver antimicrobial agents of the present invention with different silver contents.

Table 4, the table lists the content of phenols and flavonoids as active substances in several groups of cannabis extracts of the invention.

Table 5, this table lists the specific compositions of several antimicrobial agents.

As can be seen from the above tables 3 to 5, the antibacterial agents 1 to 4 of the present invention are composed of silver antibacterial agents 1 to 4 and hemp extract 1 to 4, respectively.

Table 6 shows the effect of the addition of each of the antibacterial substances in tables 3 to 5 to example 1 on the performance of the detergent in each of examples 1 in the tests of the antibacterial performance and the bactericidal performance.

Table 7 shows the effect of the addition of each of the antibacterial substances in tables 3 to 5 to example 2 on the performance of the detergent in each of examples 1 in the tests of the antibacterial performance and the bactericidal performance. The effect test method is the same as table 2.

Table 8 shows the effect of the addition of each of the antibacterial substances in tables 3 to 5 to example 3 on the performance of the detergent in each of examples 1 in the tests of the antibacterial performance and the bactericidal performance. The effect test method is the same as table 2

Table 9, which shows the effect of the addition of each of the antibacterial substances in tables 3 to 5 to example 4 on the performance of the detergent in each of examples 1 in terms of antibacterial activity and bactericidal activity. The effect test method is the same as table 2.

Table 10, which shows the effect of the addition of each of the antibacterial substances in tables 3 to 5 to example 5 on the performance of the detergent in each of examples 1 in terms of antibacterial activity and bactericidal activity. The effect test method is the same as table 2

As shown in tables 6 to 10, tables 6 to 10 respectively show the bacteriostatic and bactericidal properties of the base formulations of the examples when the antibacterial agent, silver antibacterial agent and hemp leaf extract were added. The test method was the same as that described in Table 2. As shown in the comparison of Table 2, the addition of the silver antibacterial agent and the hemp leaf extract alone improves the antibacterial and bactericidal properties of the detergent, and the silver antibacterial agent has a better bactericidal effect than the hemp leaf extract. After the antibacterial agent is added, the antibacterial performance and the bactericidal performance of the detergent are greatly improved, and the effect is better than that of a silver antibacterial agent which is singly used. The antibacterial agent of the invention, namely the hemp leaf extract and the silver antibacterial agent are compounded, so that the sterilization and bacteriostasis effects of the antibacterial agent can be obviously improved.

2. Fabric bacteriostasis rate, deodorization rate and tea stain decontamination capability test

The antibacterial materials described in tables 3 to 5 were added to the basic formulations of examples 1 to 5 listed in table 1 below to verify the bacteriostatic rate, deodorizing rate and detergency test for tea stains of the fabrics.

Table 11, which shows the bacteriostatic rate, deodorizing rate and detergency to tea stains of the fabric after adding each antibacterial substance to the basic formulation of example 1. The effect test method is the same as table 2.

Table 12, which shows the bacteriostatic rate, deodorizing rate and detergency to tea stains of the fabric after adding each antibacterial substance to the basic formulation of example 2. The effect test method is the same as table 2.

Table 13, which shows the bacteriostatic rate, deodorizing rate and detergency to tea stains of the fabric after adding each antibacterial substance to the basic formulation of example 3. The effect test method is the same as table 2.

Table 14, which shows the bacteriostatic rate, deodorizing rate and detergency to tea stains of the fabrics after adding each antibacterial substance to the basic formulation of example 4. The effect test method is the same as table 2.

Table 15, which shows the bacteriostatic rate, deodorizing rate and detergency to tea stains of the fabrics after adding each antibacterial substance to the basic formulation of example 5. The effect test method is the same as table 2.

Tables 11-15 show the effect of the added antimicrobial on the bacteriostatic rate, deodorizing rate, and stain removing ability of the fabric. The comparison result with the table 2 shows that for the fabric bacteriostatic rate, the bacteriostatic rate of the fabric can be enhanced by independently adding the silver antibacterial agent, while the bacteriostatic rate of the fabric is not changed greatly by independently adding the hemp leaf extract, but the bacteriostatic rate of the fabric is greatly improved by adding the antibacterial agent (comprising the silver antibacterial agent and the hemp leaf extract) of the invention, and the effect is better than that of independently using the silver antibacterial agent, so that the antibacterial effect of the silver antibacterial agent can be obviously enhanced by the hemp leaf extract. As for the deodorization rate of the fabric, as compared with table 2, it can be known that the deodorization rate of the fabric can be increased to a certain extent by adding the silver antibacterial agent and the hemp leaf extract alone, but the effect is not as good as that of adding the antibacterial agent, and after adding the antibacterial agent, the deodorization rate of the fabric is greatly increased, and the deodorization effect is better. The detergent disclosed by the invention can improve the dirt-removing capacity of tea stains. According to experimental data, the decontamination capability of tea stains can be improved to a certain extent by adding the silver antibacterial agent and the hemp leaf extract, but the decontamination effect of the tea stains is best by adding the antibacterial agent 1 by comparing the antibacterial agent 1, the hemp extract 1 and the silver antibacterial agent 1. Therefore, compared with the single use of the hemp leaf extract and the silver antibacterial agent, the compound use of the hemp leaf extract and the silver antibacterial agent has better sterilization and bacteriostasis performance, the antibacterial performance of the fabric is also improved, the deodorization effect is stronger, and the effect of removing tea stains is better.

The antibacterial fabric detergent obtained by compounding the antibacterial agent, the surfactant and other substances can remove stains and tea stains on fabrics and can sterilize the fabrics, so that the fabrics have strong antibacterial performance. The active components of phenols and flavonoids in the hemp leaves in the antibacterial agent can effectively stabilize the silver antibacterial agent, and can enhance the drug effect of the silver antibacterial agent, so that the antibacterial ability of the detergent is stronger.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
