性等に劣るという欠点があつた。 However, textile products coated with organic disinfectants have a short-lasting bactericidal effect, and those woven with metallic copper fibers do not have an ionic state that exhibits antibacterial properties, so their antibacterial effects are low. The drawback was that it was very small. In addition, textile products mixed with silver ion-containing zeolite particles have the drawback of not only having a small antibacterial effect but also being difficult to handle because the particles themselves are highly hygroscopic, and the product has poor processability and storage stability. .

面上への均一な接着が困難となるためである。 The meltable glass used in the present invention is a general term for glasses whose composition is adjusted in consideration of the physical and chemical properties of the glass so as to have a controlled melting rate, and which contains a silver compound or a copper compound. The meltable glass is one that can elute silver or copper ions at a fixed rate over any period of time from several hours to several years. The particle size of this meltable glass powder is preferably 100μ or less, and more preferably 25μ or less in the case of textile products such as underwear, which are final products. This is because if the particle size is larger than 100 μm, an uncomfortable tactile sensation may occur due to unevenness, and uniform adhesion onto the surface of the textile product becomes difficult.

After preparation, fibers or cloth are soaked in the treatment liquid, squeezed with a mangle, etc., and bonded by dry heat treatment at about 150°C. Here, as the aqueous emulsion binder, urethane type, acrylic ester type, etc. can be used, and as the dispersant, anion type, nonion type, etc. can be used. Further, the soluble glass powder is preferably suspended in an amount of 5% by weight or less in an aqueous solution so as to uniformly adhere to the fiber surface.

である。(Function) As described above, according to the method of the present invention, fine soluble glass powder is dispersed in an aqueous solution of an aqueous emulsion binder containing a dispersant, and fibers or cloth are immersed in the aqueous solution. Since the fiber is further processed, it is possible to adhere the soluble glass powder containing silver ions or copper ions to the fiber surface in a uniformly dispersed state. When the textile product manufactured in this way is used, water acts on the soluble glass powder and dissolves it little by little, eluting silver ions or copper ions. The eluted silver ions or copper ions are adsorbed to the cell walls of bacteria or microorganisms or concentrated within the cell membranes, inhibiting the growth of bacteria or microorganisms through a so-called oligodynamic effect, and exhibiting an antibacterial effect. Therefore, due to the above-mentioned antibacterial action, excellent effects such as prevention of bacterial growth, mold growth, and putrid odor during use of textile products are exhibited. Incidentally, the amount of silver ions or copper ions eluted is extremely small and is completely harmless to the human body and poses no problem, but the amount is sufficient for antibacterial action.

Two types of treatment liquids were prepared by dispersing the resin in an aqueous solution containing an anionic dispersant. However, the amount of powder added was 3.5% by weight. Using this treatment liquid, two types of textile products were obtained in the same manner as in Example 1, and an E. coli growth test was performed, and as a result, there was no turbidity in any of the liquids.

When we examined the number of viable bacteria after culturing for 18 hours, we confirmed that the number of viable bacteria had decreased from 340,000 before culturing to less than 100 after culturing. On the other hand, similar fabrics without soluble glass powder adhered to them after incubation.
The number has increased significantly to 360 million.
