Abstract

(57) [Summary] [Structure] A cloth-like or net-like bandage containing an antibacterial agent-binding thread. [Effect] It has excellent antibacterial properties by itself, and can prevent contamination by various bacteria not only during long-term storage but also during use.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a bandage used for assisting treatment of an affected area such as a wound or eczema.

[0002]

[Prior art]

 Conventionally, bandages are generally made of a woven or knitted fabric using various fiber yarns as raw materials and are put on the market.

[0003]

[Problems to be solved by the device]

 In conventional bandages, the bandage itself does not have antibacterial or antifungal properties. Therefore, it is unavoidable that not only contamination by various bacteria during use but also contamination by invasion of various bacteria during storage cannot be avoided. there were.

In such an actual situation, the present inventor devised the present bandage using an antibacterial agent binding yarn as a result of various studies in order to provide a bandage having an antibacterial property by itself. Is.

[0005]

[Means for Solving the Problems]

 That is, the present invention is a cloth-like or net-like dressing containing an antibacterial agent binding thread.

The antibacterial agent used in the present invention may be of any kind as long as it does not adversely affect the human body. For example, 3- (trimethoxysilyl) -propyldimethylmethyloctadecyl ammonium chloride or the like can be used. Preferred examples include quaternary ammonium salt antibacterial agents, phenyl ether antibacterial agents such as 5-chloro-2- (2,4-dichlorophenoxy) phenol, and 3- (trimethoxysilyl) -propyldimethyloctadecyl ammonium. Chloride not only has no adverse effect on the human body, but it can firmly bind the quaternary ammonium salt to the fiber by utilizing the activity of organic silicone, so there is almost no elution by washing or washing, and the antibacterial effect is stable for a long time. It is also advantageous in that it is held at.

In the present invention, the yarn to which the above-mentioned antibacterial agent is bound may be cotton yarn or any other specific type as long as it can be used for a bandage.

The method for binding the antibacterial agent to the yarn is carried out by an exhaust method or the like, and this binding may be performed at the yarn stage, or at the cloth-like stage or the mesh-like stage of the woven or knitted fabric. .

In the dressing of the present invention, the proportion of the antimicrobial agent-bonded yarn is preferably 50% or more, and particularly preferably 60% or more.

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

[0011]

[Action]

 Since the bandage of the present invention has the antibacterial agent binding thread, it has antibacterial action and antifungal action by itself.

[0012]

【Example】

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

(1) Antibacterial agent binding yarn A diluted aqueous solution of 3- (trimethoxysilyl) propyldimethyloctadecyl ammonium chloride (trade name “DC5700”: manufactured by Dow Corning Co., Ltd.) was prepared, and then cotton yarn (40th count) was prepared. ) Was dipped and then dried at 80 to 120 ° C. to remove water and methanol to obtain an antibacterial agent-bonded yarn.

(2) Bandage A fabric bandage of the present invention as shown in FIG. 1 was manufactured by weaving using the following yarns. Weft yarn: (a) Antibacterial agent binding yarn obtained above Vertical yarn: (b) Rayon yarn (40th count) (c) Stretchable polyurethane fiber yarn (spun yarn 110D)

Test Example The bandage pieces (circular pieces having a diameter of about 20 mm) and conventional bandage pieces (circular pieces having a diameter of about 20 mm) produced in the examples were used as samples, and these were used as culture test containers (vias with screw caps of about 30 ml). Bottles) and sterilized in an autoclave at 121 ° C for 15 minutes in a moist heat condition, and then 0.2 ml of a broth suspension of Staphylococcus aureus (bacteria number: 5 to 30 x 10 ⁵ cells / ml) is uniformly added. 2.4 × 10 ⁵ cells were inoculated into the cells, and after static culture at 35 to 37 ° C. for 18 hours in an incubator, the number of viable cells was measured and the increase / decrease value with respect to the number of cells was determined. The results are shown in Table 1.

[0016]

[Table 1]

With regard to the dressing of the present invention, the same result was obtained even when a sample after 10 times of washing was used as a sample.

[0018]

[Effect of device]

 Since the bandage of the present invention has excellent antibacterial properties by itself and has excellent durability, it can prevent contamination by various bacteria not only during long-term storage but also during use.
