Embodiment 1～3 and comparative example 1～3

[0081] The performance evaluation of each of the above-mentioned antiviral agents was carried out by the method described in JIS L 1922 (Test method for antiviral activity of textile products), and the antiviral activity was judged from the obtained antiviral activity value (Mv). In addition, according to JIS L 1922, the evaluation classification is as follows: 3>Mv≥2.0 exhibits an effect, and Mv≥3.0 has a sufficient effect.

[0082] Purified water was added to the antiviral agent to a concentration of 0.1% by mass. Next, add virus infection titer (virus infection titer) to this liquid 900 μ L and be 1~5×10 7 Feline calicivirus solution of PFU / mL was 100 μL, and the mixture was left to stand at 25°C for 2 hours. Then, the mixed solution was recovered and supplied to the plaque count assay to measure the virus infection titer. In addition, as a control sample, instead of the test sample, 900 μL of phosphate-buffered saline (PBS) was used, and the virus infection titer was mea...

Embodiment 4

[0090] Mix antiviral agent V1 with a binder containing acrylic resin (as binder resin) and water (as medium) so that the mass ratio of antiviral agent to binder resin is 1:1 to make a coating composition . Next, set the weight per unit area to 25g / m 2 The polyester cloth was dipped in this coating composition. Then, dry at 130°C, and the amount of antiviral agent V1 added is 3g / m 2 Anti-virus processed fabrics.

Embodiment 5

[0092] Except having used the antiviral agent V2 instead of the antiviral agent V1, it carried out similarly to Example 4, and produced the antiviral processed cloth.

Abstract

The purpose of the present invention is to provide: an anti-viral agent suitable for the inactivation of a non-enveloped virus; a composition containing the anti-viral agent; an anti-viral product; and a method for producing the anti-viral product. The anti-non-enveloped virus agent according to the present invention contains at least one component selected from (A) a compound containing an Al element, an Mg element and an O element, (B) a compound containing an alkali metal element or an alkaline earth metal element, and also containing an Si element and an O element, and (C) a hydroxide containing a bivalent metal element.

Description

technical field [0001] The present invention relates to antiviral agents suitable for inactivating non-enveloped viruses, compositions containing them and antiviral articles and methods for their manufacture. Background technique [0002] Viral diseases caused by influenza virus, norovirus, etc. have become a major problem worldwide, and have gradually aroused a high level of hygiene awareness in daily life. [0003] Viruses are roughly divided into two types according to their structure. Influenza virus is an enveloped virus with an envelope, and norovirus is a non-enveloped virus without an envelope. [0004] Conventionally, in order to inactivate viruses, methods of killing viruses by heat treatment, treatment with an organic solvent such as ethanol, treatment with a surfactant, etc. are generally known. These methods are known to be particularly effective inactivation treatments for enveloped viruses. However, non-enveloped viruses are resistant to the above treatments...
