Polypropylene fibers containing soluble glass powder containing silver ions are used, or the soluble glass powder is included in the adhesive component of the non-woven fabric, or the solubility of both the fiber and the adhesive component is improved. It is characterized in that a non-woven fabric obtained by containing glass powder is molded into a predetermined size and shape. In addition to the above configuration, the invention according to claim 2 is characterized in that the polypropylene fiber containing the soluble glass powder containing silver ions comprises a soluble glass powder containing silver ions and having a particle size of 50 μm or less. It is kneaded in a fiber material at a ratio of 30% by weight or less and has an initial elution rate of silver ions of 10 ng / cm 2 / day or more.

る。In the present invention, the synthetic fibers that can be used as the constituent fibers of the nonwoven fabric are limited to polypropylene fibers. However, if the pad is not made of hydrophobic fiber, the fiber absorbs water when it is washed, and it takes time to dry, and unnecessary silver ion elution proceeds during washing and drying, which deteriorates the antibacterial and antifungal action. Cause A typical example of the hydrophobic fiber is a polyolefin fiber, and a typical example of the polyolefin fiber is a polypropylene fiber and a polyethylene fiber. However, the latter is not limited to polypropylene fibers because fine fibers cannot be obtained.

とができる。The soluble glass containing silver ions used in the present invention is a general term for glass whose composition is adjusted in consideration of physical and chemical characteristics of glass so as to exhibit a limited melting rate. Thus, a soluble glass containing silver ions can elute silver ions at a defined rate over any period of hours to years. Then, the eluted silver ions are adsorbed on the cell walls of bacteria or microorganisms or condensed in the cell membrane to inhibit the growth of bacteria or microorganisms by a so-called oligodynamic effect and exert an antibacterial function.

ている。Generally, fungi and bacteria are propagated when the humidity is high, and when the humidity is low, the fungi and bacteria are not propagated so much. In contrast, soluble glass has a temperature
It elutes a large amount of its components when the humidity is high, and it elutes little when the temperature and humidity are low, so it is in direct proportion to the growth of mold and bacteria. That is, when bacteria or the like are easily propagated, a large amount of the antibacterial and antifungal component is eluted from the soluble glass, and conversely, when the bacteria and the like are hardly propagated, the antibacterial and antifungal component is hardly eluted from the soluble glass. There is.

る。The amount of the soluble glass added varies depending on the particle size, but when the particle size is 50 μm or less, the range is preferably 0.1 to 30% by weight based on the weight of the nonwoven fabric. As a metal that emits ions as an antibacterial and antifungal component to be contained in soluble glass, copper, zinc, and other metal compounds having an antibacterial and antifungal function are conceivable, but safety,
Due to its antibacterial and antifungal properties, it is limited to those that release silver ions.

持続の面から特に有利である。The components of the soluble glass usable in the present invention include network-forming oxides such as SiO 2 , B 2 O 3 and P 2 O 5 , or Na 2 O, K 2 O, Cao and Mg.
It consists of a network-modifying oxide such as O, BaO, Al 2 O 3 , TiO 2 , and ZnO. When it absorbs moisture, the soluble glass gradually dissolves due to the moisture, and the silver ions contained in the glass composition are eluted. Any one can be used without particular limitation, but when using the fusible glass having the composition according to claim 3, it is particularly advantageous in terms of preventing yellowing of the bed pad and maintaining the antibacterial and antifungal action.

The result was cm 2 / day. Next, to prevent the growth of green mold, the temperature was 25 ° C on potato dextrose agar medium.
After culturing for 1 week in, the growth inhibition zone was observed. No blue mold was found around 5 mm around the nonwoven fabric. Furthermore, after this, after dipping this test subject in water for 1 day, a decrease in the blue mold growth inhibition function due to the elution of silver ions was also observed, but the length of the blue mold inhibition zone was only slightly reduced to 4 mm, and it was wet. As a result, a sufficient effect can be expected as a pad for a bed that absorbs a large amount of water with the foot.
