  The disinfectant composition for textile products of the present invention can be used for various textile products that are concerned about the growth of bacteria, such as fabrics, clothes, cloths, beddings, towels and the like.

Since the composition and method of the present invention have bactericidal properties against pathogenic bacteria, they can be used for sterilizing textile products used not only for general households but also for medical care and nursing care, while often used in clothing and laundry environments. It can be used to sterilize causative bacteria that are involved in the recurring odor that is emitted and the odor reappears when the fiber is dried and absorbs moisture. For example Moraxella (Moraxella) bacteria, Acinetobacter (Acinetobacter) bacteria, shade MONAS (Pseudomonas) bacteria, Bacillus (Bacillus) bacteria, Sphingomonas (Sphingomonas) bacteria, Ralstonia (Ralstonia) bacteria, queue pre Avi Das ( Cupriavidus) bacteria, cyclo Acetobacter (Psychorobacter) bacteria, Serratia (Serratia) bacteria, Escherichia (Escherichia) bacteria, Staphylococcus (Staphylococcus) bacteria, Burkholderia (Burkholderia) bacteria and the like.

Specifically, Moraxella sp (Moraxella sp.), Moraxella Osuroenshisu (Moraxella osloensis), Acinetobacter Radio Regis Tense (Acinetobacter radioresistens), Acinetobacter Junii (Acinetobacter JuNii), Acinetobacter calcoaceticus (Acinetobacter calcoaceticus ), Serratia marcescens (Serratia marcescens), Escherichia Korai (Escherichia coli), Staphylococcus aureus (Staphylococcus aureus), Pseudomonas Alcaligenes (Pseudomonas alcaligenes), Bacillus cereus (Bacillus cereus), Bacillus subtilis (Bacillus subtilis), cyclo Arthrobacter Pasi Fi forsythensis (Psychrobacter pacificensis), cyclo Arthrobacter Gurashinkora (Psychrobacter glacincola), Sphingomonas Yanoi Yae (Sphingomonas yanoikuyae), Ralstonia sp (Ralstonia sp.), Saccharomyces cerevisiae (Saccaromyces cerevisiae), Rhodotorula Mushiraginosa (Rhodotorula mucilaginosa), Rhodotorula Surufie (Rhodotorula slooffiae), queue pre-Avi Das oxa Ratih dregs (Cupriavidus oxalaticus) And Burkholderia cepacia . Of these, many Moraxella bacteria exist in the living environment. Moraxella bacteria are resistant to drying, and the bacteria attached to the fiber cannot be sterilized by drying after washing with a general detergent. In addition, it has been found that the bacteria present in clothing produce 4-methyl-3-hexenoic acid (4M3H) odor, which is one of the dry odors of clothing.

  According to the composition and treatment method of the present invention, 4-methyl-3-hexenoic acid, which has a very low threshold as a raw dry odor and is difficult to remove, can be produced, and Moraxella spp. Excellent in dry resistance can be sterilized. . The present invention is useful for sterilization of Moraxella bacteria adhering to textiles.

(3) Evaluation (3-1) Preparation of Bacterial Suspension The test bacterium was inoculated into an SCDLP agar medium and cultured at 37 ° C. for 1 day, and this was used as a preculture plate. The colony surface is scraped from the pre-culture plate with congeal, and the bacterial solution suspended in ion-exchanged water is centrifuged at 2800 rpm, 20 min, 25 ° C. After removing the supernatant, Adjusted to ⁹ cfu / ml.

(3-2) Bactericidal Evaluation Method 0.1 mL of the bacterial suspension prepared in (3-1) above is added to 10 ml of the textile product bactericidal composition of Table 1 or Table 2, and 15 minutes at 25 ° C. and 150 rpm. After stirring at 0.1 mL, 0.1 mL of this mixed solution is taken and added to 0.9 mL of LP medium and mixed well to reduce the effect of the fungicide composition for textiles on bacteria. Solutions diluted 10-fold and 100-fold with stock solution and LP medium were subjected to pour culture on SCDLP agar medium. In addition, for the preparation of the detergent composition for textile products, water having a hardness of 4 ° DH or 10 ° DH added to sterile ion exchange water using calcium chloride and magnesium chloride at a mass ratio of 7/3 is used as a solvent. It was. After culturing at 37 ° C. for 24 hours, the number of colonies grown is counted. The result of conducting a similar test with water having a hardness of 4 ° DH or 10 ° DH added to sterilized ion-exchanged water using calcium chloride and magnesium chloride at a mass ratio of 7/3 instead of the disinfectant composition Was used as a blank, and the bactericidal property was evaluated by the difference in the number of bacteria from the blank with water having the same hardness as the solvent. The results are shown in Tables 1 and 2. This evaluation result correlates with the bactericidal effect against bacteria present in the textile product.

* The bactericidal property is the difference in the number of bacteria from the blank, and the closer to 7, the higher the bactericidal effect.

In addition, the fungicidal compositions of the examples also exhibit a bactericidal effect against bacteria belonging to the genus Acinetobacter isolated from any used clothing.

  The disinfectant composition for textiles of the present invention has an excellent bactericidal effect against bacteria present in textiles such as clothing. Furthermore, since the bactericidal effect of the present invention is not easily affected by the hardness of water, when the treatment method is performed in which the composition of the present invention is diluted with tap water and the textile is immersed in the diluted solution, tap water is used. This is an advantageous invention because there is little need to consider the hardness.
