Therefore, it is particularly important to use effective antimicrobial agents on household items to maintain self-cleaning thereof to combat microbial contact infections.
At present, commercial fabrics with antibacterial effects usually use compounds with antibacterial effects such as cations, silver-containing compounds and the like to care the fabrics before leaving factories, so that a plurality of antibacterial agents are attached to the surfaces of the fabrics, and thus the antibacterial effects are achieved, but the antibacterial agents gradually separate from the surfaces of the fabrics along with the increase of daily washing times, and finally the antibacterial effects of the fabrics are lost. Therefore, in view of the above situation, the main way to solve this problem in the industry is to use a detergent with antibacterial effect, and the treated fabric may also have antibacterial effect, which is equivalent to a washing process being a care process. However, such detergents have a relatively narrow long-acting antimicrobial spectrum, typically bacterial, and do not involve fungi. Some even involve only a certain class of bacteria, such as gram-positive bacteria. Therefore, there is an urgent need to develop a household fabric antibacterial care agent which has the advantages of water washing resistance, broad antibacterial spectrum and convenient use.

Interpretation of the terms
Unless otherwise indicated, the terms used in the claims and other sections of this application have the meanings indicated below.
By "fabric care agent" is meant a class of compositions containing a benefit agent that are brought into contact with a substrate (i.e., fabric) to be contacted and subjected to a specific treatment step to transfer the benefit agent to the surface of the substrate for the purpose of imparting a benefit to the substrate. The fabric care agent provided by the invention is a composition for endowing fabric with a long-acting antibacterial effect resistant to water washing, and the composition is contacted with the fabric in a washing system, so that a beneficial agent (long-acting antibacterial component) is transferred to the surface of the fabric, and the fabric is endowed with the long-acting antibacterial effect resistant to water washing. The specific treatment step is only a daily washing process, and the step of curing the fabric by heating, curing and the like is not required to be additionally added.
The terms "antibacterial" and "antibacterial" are not distinguished, and refer to the process of killing microorganisms or interfering with the growth and reproduction of microorganisms and their activity by chemical or physical methods, and are a collective term for sterilization and bacteriostasis.
The antibacterial efficacy referred to in the "antibacterial efficacy" means the ability to kill or inhibit microorganisms. The antibacterial efficacy can be expressed numerically by using the sterilization rate (IR) obtained by testing the laboratory standard strain, and when the sterilization rate is less than or equal to 50%, the sample has no antibacterial efficacy. When the sterilization rate is more than or equal to 50%, the sample has the antibacterial effect. When the sterilization rate is more than or equal to 99.9%, the sample has good antibacterial effect.
"Hardness" refers to the total amount of calcium and magnesium ions in water, calculated as the weight of calcium carbonate, per weight of water in ppm, and the hard water used in the present invention has a hardness of 342ppm (calculated as CaCO3 and a molar ratio of calcium and magnesium ions of 3:2).
"Long-acting antimicrobial efficacy" refers to the change in the number of microorganisms that result from a fabric subjected to a fabric care agent that is co-cultured with a microorganism for 2 days after it has been subjected to a particular wash step. The long-acting antibacterial effect and the long-acting antibacterial rate (LIR) are expressed in a numerical mode. When the LIR is more than or equal to 90.00%, the test sample has good long-acting antibacterial effect.
"Specific wash step" refers to a step of treating a fabric with a fabric care agent, without a step of heat treatment. The specific step S00 is as follows: the cotton cloth or polyester fabric is cut into round pieces of 4.5cm to 5cm in diameter, called cloth pieces. A hard aqueous solution of 100g of a 5% strength fabric care composition was prepared in a 250ml long neck beaker. Adding a magnetic stirring rotor with the diameter of 6cm into each long-neck beaker containing liquid, putting 15-17 cloth pieces into each cup, stirring and washing on a magnetic stirrer at 300rpm for 20min, and pouring out the liquid; and then taking out the cloth piece of each long-neck beaker, squeezing the cloth piece to water, spreading the cloth piece in a clean container, and naturally airing for standby.
The term "durable antimicrobial efficacy against water wash" refers to the change in the number of microorganisms that results from the fabric being subjected to a particular wash step of the fabric care agent, then washed several times with the detergent, and then the fabric being co-cultured with the microorganism for 2 days. The term "wash-resistant" refers to washing with water as the wash medium, twice with a standard laundry detergent without antimicrobial agent, without causing a significant change in the long-lasting antimicrobial efficacy. The long-acting antibacterial effect of the water-resistant type is expressed by numerical value of the long-acting antibacterial rate (LIR (d)) after d times of washing. d represents the number of washes. For example, LIR (2) refers to the long-acting antibacterial rate of the fabric after twice washing, and LIR (2) is more than or equal to 90%, and the fabric is said to have long-acting antibacterial efficacy of water resistance. For example, LIR (3) refers to the long-acting antibacterial rate of the fabric after three times of washing, and LIR (3) is more than or equal to 90%, so that the fabric has the long-acting antibacterial effect of water resistance.

Examples 1 to 4 and comparative examples 1 to 4
The compositions of examples 1 to 4 and comparative examples 1 to 4 were prepared according to the above-described preparation methods; table 3 shows the specific compositions of the compositions of examples 1 to 4 and comparative examples 1 to 4.
Table 3 composition of examples 1 to 4, comparative examples 1 to 4
Examples 5 to 8 and comparative examples 5 to 8
Examples 5 to 8, comparative examples 5 to 8, and table 4 clearly indicates the differences between each example and comparative example from example 1, were prepared according to the above preparation method.
Table 4 the differences between examples 5 to 8, comparative examples 5 to 6
Comparative tests on the efficacy of examples 1-8 and comparative examples 1-8
According to the test methods provided in the specification of the present invention, the antibacterial efficacy, the long-acting antibacterial efficacy, and the long-acting antibacterial efficacy against washing were tested for the examples and the comparative examples. Wherein, the antibacterial efficacy test objects are examples and comparative examples; while the fabric (piece) treated by the examples and the comparative examples is subjected to the long-acting antibacterial efficacy test, the fabric (piece) treated by the examples and the comparative examples and subjected to the washing liquid washing is subjected to the washing resistant long-acting antibacterial efficacy test. The liquid laundry detergent is a standard liquid laundry detergent without antibacterial agents.
1. Antibacterial efficacy of examples and comparative examples
According to the above antibacterial efficacy test method, examples 1 to 8, comparative examples 1 to 8 were tested for antibacterial efficacy against different strains. It can be seen from Table 5 that the examples have good antibacterial efficacy against bacteria and fungi. Only with a broad antimicrobial spectrum, it is possible to impart a broad, long-lasting antimicrobial efficacy to the fabric in a subsequent step.
While comparative examples 2,3,6, and 7 failed to achieve antibacterial efficacy against fungi, the IR value was less than 50%. The nonionic surfactant content in comparative example 6 was excessive, and the ratio range of composition a was out of the ratio range required by the present invention. Too much nonionic surfactant may antagonize composition a. The chelating agent of comparative example 7 was much lower than in the examples; hard water may have an antagonistic effect on composition a.
Table 5 antibacterial efficacy of examples and comparative examples
2. Long-acting antibacterial efficacy of examples and comparative examples
According to the long-acting antibacterial test method, the long-acting antibacterial effects of the test examples and the comparison examples aiming at different strains are tested. As can be seen from table 6, the examples give the treated fabric good long-lasting antimicrobial efficacy and good data parallelism, demonstrating that the technical solution adopted by the invention is effective and viable. Aiming at bacteria, whether the bacteria are gram-positive bacteria or gram-negative bacteria, the long-acting antibacterial rate of the fabric treated by the embodiment is over 99.9 percent, namely the long-acting antibacterial efficacy grade is I, and the like. Aiming at fungi, the long-acting antibacterial rate of the fabric treated by the embodiment is above 90%, namely the long-acting antibacterial efficacy grade is II, and the like. It can be seen that only when the amounts of component A1, component A2, and nonionic surfactant are within the scope of the present invention, components A1 and A2 are effectively distributed and combined on the fabric surface, giving the fabric a long-lasting antimicrobial effect.
Comparative examples 1 and 4 were directed against bacteria, both gram positive and gram negative, and the long-acting antibacterial rate of the fabrics treated in the examples was 99.9% or more, i.e., the long-acting antibacterial efficacy grade was I, etc. However, these two comparative examples are unstable in long-acting antibacterial efficacy against fungi, and the inventors have not obtained reliable and repeatable test results by repeating the experiment a plurality of times. It is possible that the components A1 and A2 and the nonionic surfactant are effectively distributed and combined on the surface of the fabric at the same time when the content of the nonionic surfactant is within a reasonable content range, so that the antibacterial effect with long-acting effect is generated. The component A1 of the comparative example 4 has too high content and too low content of A2, and the finished fabric has poor long-acting antibacterial capability, which indicates that the component A1 and the component A2 must be reasonably compounded to produce good effects.
The surfactant of comparative example 5 was much lower than the examples and did not impart long-lasting antimicrobial efficacy to the treated fabric. The proper level range of nonionic surfactant is described as helping composition a migrate and anchor to the fabric surface, which in turn exerts an antimicrobial effect.
The surfactant of comparative example 8 was much lower than the examples and did not impart long-lasting antimicrobial efficacy to the treated fabric. It is explained that the adhesion promoter CAT-HEC is essential for the technical solution of the invention. The comparative examples lacking the adhesion promoter failed to complete a normal temperature long-acting antimicrobial finish of the fabric surface.
Table 6 long-acting antimicrobial efficacy of examples and comparative examples
3. Long-acting antibacterial efficacy of the examples against washing
According to the long-acting antibacterial efficacy test method for washing resistance, the test examples are directed to the long-acting antibacterial efficacy (washing 2 times and 3 times) of different strains. It can be seen from tables 7 and 8 that the examples impart good long-lasting antimicrobial efficacy against water wash to the treated fabric and that the data parallelism is good. Comparison of Table 6 shows that the fabrics treated in the examples can withstand at least two launderings while maintaining a constant level of long-lasting antimicrobial efficacy. Namely, for bacteria, whether gram positive bacteria or gram negative bacteria, after the fabric treated by the embodiment is subjected to washing for at least two times, the long-acting antibacterial rate of the fabric resistant to washing is over 99.9 percent, namely, the long-acting antibacterial efficacy grade is I, and the like. For fungi, after the fabric treated by the embodiment is washed at least twice, the long-acting antibacterial rate of the fabric resistant to washing is over 90 percent, namely the long-acting antibacterial efficacy grade is II, and the like.
