Abstract: An antistatic fibrous material manufactured by treating a natural and/or regenerated fibrous material with both (1) at least one di-halogeno-s-triazine that has at least one hydrophilic group, and (2) urea, thiourea, and an amino acid, or a combination of two or more of said three compounds. The treatment includes the following steps: (a) saturating a natural and/or regenerated fibrous material with a solution that contains (1) a di-halogeno-s-triazine having at least one hydrophilic group and (2) urea, thiourea, and an amino acid, or a combination of two or more of said three compounds (b) heating said saturated material at 30° C.-60° C., and (c) heating said saturated material at 60° C.-90° C.

Abstract: This invention consists of an accommodation bag such that one outer bag accommodates multiple inner accommodation bags and at least one of the inner accommodation bags is a liquid-accommodation bag from which a liquid flows. Also, the liquids or goods that flow out from other multiple accommodation bags in the outer bag are processed and used by mixing with or coming into contact with each other. Therefore, it is also possible to use the processed liquid for drinking or eating by taking it via the bottom of the outer bag. As a heating means, either an outside means, such as a microwave oven or the like, or an independent container installed inside the liquid-accommodation bag, is used. The heat-generation means inside the liquid-accommodation bag is such that heat is generated when there are combined together at least two kinds of materials that generate heat by chemically reacting together, and such that only such generated heat can be utilized.
