BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant pillow filler having excellent antimicrobial properties, and more particularly, to treating a plant material used as a pillow filler with a solution containing at least one of silver nano and chitosan to impart antimicrobial properties.

Pillow filling material uses cotton wool, synthetic fiber wool, goose down hair, synthetic resin molding and vegetable material. In particular, recently, vegetable materials such as millet, buckwheat bark, red beans, and soybeans are used a lot as eco-friendly materials that are effective for sound sleep according to the well-being trend. The vegetable material, which is an environmentally friendly material, is widely used because it has a variety of raw materials, and it is easy to absorb user's feel and sweat during sleep.

However, the plant material is not easy to be stored because the fungus, insects, etc. during storage, and in particular, buckwheat pillow has a problem that the endotoxin (endotoxin, endotoxin) is released that can significantly worsen asthma symptoms It is known.

Therefore, according to the present invention, while improving the antimicrobial properties of the plant pillow fillers, which are environmentally friendly and have a good night's sleep effect, and prevent the occurrence of mold, harmful microorganisms and insects, buckwheat pillows may worsen asthma symptoms It is a technical task to provide a vegetable pillow filling material that can prevent the occurrence of endotoxin in advance.

Therefore, according to the present invention, a chitosan-silver nanomixture obtained by mixing a chitosan solution having a chitosan content of 5 to 20 wt% and a silver nano aqueous solution containing 100 to 200 ppm of silver nano with a size of 10 to 50 nm and containing a cationic or nonionic surfactant is present. The vegetable material is mixed in a volume ratio of 1: 2 to 2: 1, and then maintained for 5 minutes to 3 hours so that the vegetable material contains the chitosan solution, and then dehydrated and dried in a hot air or a dry oven. Provided is a method for producing a vegetable pillow filler having excellent antibacterial properties.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a plant pillow filler having excellent antimicrobial properties, and particularly, to providing antimicrobial properties by treating any one selected from millet, buckwheat bark, red beans, and beans used as a pillow pillow with a solution containing silver nano and chitosan.

The treatment solution of the present invention may be a mixed solution of silver nano solution and chitosan solution, in particular, the type and treatment time of the treatment solution is adjusted according to the type of vegetable material to be treated. It is preferable to use an impregnation method for the treatment method of the following treatment, after impregnating the treatment liquid after containing the vegetable material in the network, or directly impregnated the vegetable material into the reactor.

The silver nano solution is used that contains 100 ~ 200ppm silver nano of less than 50nm, the antimicrobial effect is weak when the silver nano content is less than 100ppm, the problem that the increase of manufacturing cost and waste of silver nano is caused when it exceeds 200 ppm have. The silver nano solution and the vegetable material have a volume ratio of 1: 1 to 1: 2.5 to bring about effective antibacterial effect. The treatment time should be adjusted according to the type of plant material to be treated. For millet rice, impregnation should be performed for 5 to 10 minutes to prevent swelling of millet rice, and for buckwheat husk, it should be impregnated for 2-3 hours. Complete absorption can be achieved.

Next, the chitosan solution is described. A chitosan oligosaccharide having a deacetylation degree of 75 to 98% is added to distilled water and dissolved with an organic acid such as hydrochloric acid or acetic acid to prepare a chitosan solution having a chitosan content of 5 to 20 wt%. The ratio of the chitosan solution and the vegetable material is preferably 1: 2 to 2: 1, but less than 1: 2, it is difficult to express sufficient antimicrobial activity, and when it exceeds 2: 1, problems such as waste of the treatment solution occur. do.

In the present invention, a chitosan-silver nanomixture and a vegetable material, which contain a chitosan solution containing 5 to 20 wt% of chitosan, a silver nanosolution containing 100 to 200 ppm of silver nano with a size of 10 to 50 nm, are mixed at a volume ratio of 1: 2 to 2: 1. It can be mixed and used as a process liquid. When the silver particles on the colloid are mixed with the chitosan solution, it is preferable to use a silver nano solution containing a cationic or nonionic surfactant so that additives such as the surfactant used in the preparation of the silver nano solution do not react with the chitosan.

According to the present invention there is provided a vegetable pillow filler having excellent antimicrobial properties, characterized in that any one or more of silver nano and chitosan is contained in any one selected from the group consisting of millet, buckwheat bark, red beans, beans. It is possible to provide a pillow that is filled with pillows to express the unique properties of the plant pillow fillers while having excellent antibacterial properties.

The following examples are given as non-limiting examples of the method for producing a vegetable pillow filling of the present invention.

  Example 2

A chitosan-silver nanomixture (3,000 ml) and 300 g (2,500 ml) of buckwheat husks were prepared by mixing a chitosan solution containing a 20% by weight chitosan solution and a silver nano-solution containing 100 ppm of silver nanoparticles (50 nm or less) Then, buckwheat skin is poured into a 5L beaker and chitosan-silver nanomixture is poured. After stirring the chitosan-silver nano mixture and the buckwheat bark for 3 hours, the buckwheat bark was removed and placed in a tri, dried at 100 ℃ in a drying oven to prepare a vegetable pillow filling material.

 Comparative Example 1

300g of buckwheat husks in which the silver nano solution was not impregnated was obtained to obtain Comparative Example 1.

 Comparative Example 2

A vegetable pillow filler was prepared in the same manner as in Example 1 except that the silver nanoparticles containing 50 ppm of silver nanoparticles were used.

The vegetable pillows prepared in Examples and Comparative Examples were subjected to the antimicrobial test by a simple test method using the KS M 0146 SHAKE FLASK METHOD method, and the results are shown in Table 1 below.

result Remarks Example 2 colony ^{Note 1)} None (FIG. 2) Excellent antibacterial activity Comparative Example 1 colony occurrence (FIG. 3) Antimicrobial Comparative Example 2 TNTC ^{Note 2)} Occurrence (Figure 4) No antimicrobial

^{Note 1)} Colony: A colony appears as a single bacterium with a red dot.

^{Note 2)} TNTC (Too Numberous To Count): The entire medium is red due to the collision between colony type bacteria.

As shown in Table 1, Example 2 shows excellent antimicrobial properties, which can prevent the access of microorganisms or insects, but Comparative Example 1 and Comparative Example 2 showed poor antimicrobial properties or no antimicrobial properties.

The present invention improves the antimicrobial properties of vegetable pillow fillers that are eco-friendly and have a good night's sleep when used to prevent the occurrence of fungi, harmful microorganisms, insects, etc., while in the case of buckwheat pillows, the generation of endotoxins that may worsen asthma symptoms. It has the advantage of providing a vegetable pillow filling material that can be prevented in advance.
