[Problem] In a conventional protective garment, the internal environment of a garment body becomes worse due to the wearer’s exhaled breath, and therefore the wearer suffers from the difficulty of having to perform work for a long time under unpleasant conditions. [Solution] This protective garment, which is used to protect a human body against foreign substances, comprises a garment body that covers at least a portion of the human body, wherein a fan that supplies external air to the inside of the garment body is embedded in the garment body, the fan comprises a filter for filtering the external air supplied to the garment body by the fan, and thus the protective garment, which suppresses a deterioration of the internal environment of the garment body, so that work can be performed for a long time under pleasant conditions, can be provided.

The present application relates to a composition, textile, and mask for reducing the inhalation of pollutants. The composition includes an aqueous solution of an inorganic iodide compound, a metal phthalocyanine, and a polymeric binder. The inorganic iodide can be cuprous iodide, the metal phthalocyanine can be iron phthalocyanine, and the polymeric binder can be polyvinylpyrrolidone or polyvinyl alcohol. This pollutant-inactivating composition neutralizes pollutants such as nitrogen dioxide, sulfur dioxide, ozone, volatile organic compounds and other unpleasant airborne agents, without requiring elevated temperatures or bulky canisters containing adsorbents. Optionally, a humectant can also be incorporated into the coating solution to retain moisture in the active filter matrix, which enhances the activity of the composition to inactivate oxidizing gases and other toxic constituents of air pollution.
