Therefore, the bedding can obtain the health and health care functions by researching and preparing the finishing agent with the antibacterial and anti-mite functions, thereby playing the role of preventing diseases and having very important significance and wide application prospect.

Bacteria and mites are all micro-organisms invisible to the naked eye, and under appropriate circumstances they can rapidly multiply with sweat, secretions and shed dander secreted by humans as nutrients. The figure is used in household articles and environments such as mattresses, bedding, plush toys, carpets, sofas, kitchens, bathrooms and the like. Secretion, metabolite and corpse of mites are allergens which can cause diseases, and allergic dermatitis and respiratory diseases are easily caused. If some germs are brought in by dust mites, respiratory tract infection or inflammation of human body is also easy to cause. According to the world health organization, 70% of asthma is caused by dust mites.

In the hot and humid quilt, bacteria and mites can breed and propagate quickly, so that the skin of a human body is infected, and the fabric stained with sweat and human secretion generates foul smell, which has great harm to the sleep quality and health of people. Therefore, bedding has antibacterial, anti-mite and deodorizing functions, and becomes one of the research hotspots of the current multifunctional antibacterial and anti-mite agent. In the current research on anti-bacteria and anti-mite, most of the main substances for anti-mite sterilization are artificially synthesized and have high toxicity, which seriously damages the health of human bodies.

Therefore, there is a need to provide an antibacterial and acaricidal agent, which can be widely used in bedding, can effectively sterilize and acarid, has no irritation to human skin, is safe and environment-friendly, and improves the living environment of people.

Textile articles can also be directly soaked in 10% of the antibacterial and anti-mite agent prepared by the embodiment of the invention for 15-20 minutes, and then washed and dried conventionally.

In order to further illustrate the beneficial effects of the invention, the following method is adopted to perform effect test on the product prepared by the embodiment of the invention:

(1) acute transdermal toxicity test: skin irritation/corrosion experiments were performed according to technical safety regulations for cosmetics (2015 edition) chapter vi toxicology experimental method 4.

(2) Acute eye irritation test: the test was carried out according to the second part of the technical Specification for cosmetic safety (2015 edition).

(3) Antibacterial ability test: the antibacterial and anti-mite agent treated cloth is tested by using a shaking culture method, and the used strains are staphylococcus aureus and escherichia coli, and the specific reference standard is ASTM E2149.

(4) And (3) antibacterial durability test: the antibacterial and anti-mite treated cloth after being washed for 5 times by the antibacterial and anti-mite agent is tested according to the standard ASTM E2149.

(5) Testing the anti-mite capability: and (3) detecting the effect of the antibacterial and anti-mite agent on treating the cloth to repel mites, specifically referring to the evaluation of the anti-mite performance of the textile with GB/T24253 laid-open material 2009.

(6) Testing the anti-mite endurance capacity: and testing the antibacterial and anti-mite finished cloth after the antibacterial and anti-mite agent treated cloth is washed for 5 times according to the standard GB/T24253-containing 2009.

The detection results are as follows:

TABLE 1 statistical table of test results of products manufactured in each example

And (3) analyzing a test result:

comparing and analyzing the detection results of the products of examples 1 to 7 in table 1, it can be seen that the mixture of the extracts of the cymbopogon flexuosus and the extracts of the loquat leaves as the antibacterial agent has a synergistic antibacterial effect, and the antibacterial efficiency is significantly higher than that of the single extract of the cymbopogon flexuosus or the single extract of the loquat leaves; the folium artemisiae argyi volatile oil and the stemonine are mixed to be used as the anti-mite agent, so that the anti-mite effect is synergistic, and the anti-mite rate is obviously higher than that of the single folium artemisiae argyi volatile oil or the single stemonine.

Comparing the results of the tests of the products of examples 3, 6, 7, 9, 11 and 12 in table 1, it can be seen that the antibacterial efficiency is significantly better than other ratios when the weight ratio of the vanilla extract to the loquat leaf extract is 2: 1. The weight ratio of the folium artemisiae argyi volatile oil to the stemonine which are used as the anti-mite agent components is 2:1, and the anti-mite effect is obviously better than that of other mixture ratios.

Comparing and analyzing the product detection results of examples 6, 9, 10, 13 and 14 in table 1, it is known that when the dosage of the antibacterial agent is higher than 1% and the dosage of the anti-mite agent is higher than 2%, the dosages of the emulsifier, the dispersant and the cross-linking agent should be increased correspondingly, the emulsifier caprylic-capric glyceride is preferably not lower than 0.8%, the dispersant sodium tripolyphosphate is preferably not lower than 0.35%, and the cross-linking agent waterborne polyurethane is preferably not lower than 0.25, which is mainly because when the dosages of the emulsifier, the dispersant and the cross-linking agent are too low, the adsorption between the antibacterial agent and the anti-mite agent and the bedding surface is insufficient, thereby affecting the antibacterial and anti-mite effects of the product. The use amount of the emulsifier, the dispersant and the cross-linking agent is too high, so that adverse effects are brought, and the emulsifier, the dispersant and the cross-linking agent are mainly interacted, so that the antibacterial agent and the anti-mite agent are easily wrapped, and the antibacterial agent and the anti-mite agent cannot fully play a role; therefore, in the present invention, the amount of the emulsifier is preferably 0.8 to 1%, the amount of the dispersant is preferably 0.35 to 0.4%, and the amount of the crosslinking agent is preferably 0.25 to 0.3%.

Comparing and analyzing the detection results of the products of examples 6, 8, 9, 14 and 15 in table 1, it can be seen that when the dosage of the antibacterial agent is 0.5-8% and the dosage of the anti-mite agent is 1-10%, the antibacterial and anti-mite effects of the product are enhanced along with the increase of the dosages of the antibacterial agent and the anti-mite agent; when the using amount of the antibacterial agent is more than 8 percent and the using amount of the anti-mite agent is more than 10 percent, the antibacterial and anti-mite effects of the product are almost unchanged, and from the aspects of economic cost and antibacterial and anti-mite effects, the using amount of the antibacterial agent is preferably 4-8 percent and the using amount of the anti-mite agent is preferably 5-10 percent.

In order to further illustrate the beneficial effects of the invention, the invention also adopts the red bayberry leaf extract to replace the loquat leaf extract in the embodiments 1-14 of the invention to prepare the antibacterial and anti-mite agent, and finally the measured antibacterial and anti-mite performance of the product is obviously inferior to that of the products obtained in the embodiments 1-15 of the invention.

The embodiments of the present invention have been described in detail, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
