[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bandage mainly used for assisting treatment of an affected area such as a wound and eczema.

[0002]

2. Description of the Related Art Conventionally, a bandage is generally made of a woven or knitted fabric using various fiber yarns, and is available on the market.

[0003]

[Problems to be Solved by the Invention] Conventional bandages have no antibacterial property or antifungal property in the bandage itself, so that they are not only contaminated by bacteria during use but also by invasion of bacteria during storage. In fact, it was inevitable.

[0004] Under such circumstances, the present inventors have conducted various studies to provide a bandage which retains antibacterial properties by itself, and as a result, devised a bandage of the present invention using an antibacterial binding yarn. It is.

[0005]

That is, the present invention provides a 3-
It is a cloth-like or reticulated bandage containing an antibacterial agent-bound yarn containing (trimethoxysilyl) -propyldimethyloctadecyl ammonium chloride as an active ingredient.

[0006] The antibacterial agent 3- (trimethoxysilyl) -propyldimethyloctadecyl ammonium chloride used in the present invention not only has no adverse effect on the human body, but also uses the organic silicone activity to strongly attach the quaternary ammonium salt to fibers. , So that there is almost no elution due to washing or water washing, and particularly good results can be obtained in maintaining the antibacterial effect stably for a long period of time.

In the present invention, the yarn to which the above-mentioned antibacterial agent is bound is not particularly limited as long as it can be used for a bandage, such as cotton yarn.

[0008] The method of binding the antibacterial agent to the yarn is carried out by an exhaustion method or the like, and this binding may be carried out at the yarn stage, or at the cloth stage or net stage of the woven or knitted fabric. .

In the dressing of the present invention, the ratio of the antibacterial agent binding yarn is preferably at least 50%, particularly preferably at least 60%.

The cloth-like or net-like bandage according to the present invention may be stretchable or non-stretchable.

[0011]

[Function] Because the present invention bandage has an antibacterial agent binding yarn,
It has antibacterial and antifungal action by itself.

[0012]

The present invention will be further described with reference to the following examples.

(1) Antibacterial agent binding yarn 3- (trimethoxysilyl) propyldimethyloctadecyl ammonium chloride (trade name “DC570”)
0 ": manufactured by Dow Corning Co., Ltd.) and then immersed in a cotton yarn (40 count).
After drying at 80 to 120 ° C., water and methanol were removed to obtain an antibacterial agent-bound yarn.

(2) Bandage The following yarns were woven to produce a cloth bandage of the present invention as shown in FIG. Weft yarn: (a) Antibacterial agent binding yarn obtained above Warp yarn: (b) Rayon yarn (40 count) (c) Stretchable polyurethane fiber yarn (spun yarn 110D)

Test Example The bandage pieces (circular pieces having a diameter of about 20 mm) produced in the examples and the conventional bandage pieces (circular pieces having a diameter of about 20 mm) were used as samples, and these were used as culture test vessels (about 30 ml vials with screw holes). ), Autoclaved at 121 ° C. for 15 minutes, and then sterilized by pouring in 0.2 ml of a broth suspension of Staphylococcus aureus (number of bacteria: 5 to 30 × 10 ⁵ cells / ml). 2.4 × 10 ⁵ cells were inoculated and cultured at 35-37 ° C. for 18 hours in an incubator, and the number of viable cells was counted to determine the increase / decrease in the number of cells. The results are shown in Table 1.

[0016]

[Table 1]

Similar results were obtained by using the bandage of the present invention after washing 10 times as a sample.

[0018]

[Effects of the Invention] The bandage of the present invention has excellent antibacterial properties by itself and has excellent durability, so that it can prevent contamination by various bacteria during use as well as during long-term storage. Can be.
