Description

  The present invention proposes a new technique for allowing a normally dry cloth-like sheet material to be used in an arbitrarily and freely wet state without any special wet treatment with external moisture. is there.

Various cloth-like sheet materials are often used in a state of being moistened with water or other liquids depending on the application.
Here, the cloth-like material is not limited to cloth materials such as towels and hand towels, but can be assumed to be preferably used in a wet state, such as non-woven fabric made of cotton or rayon, paper tissue, etc. Is also included.

  In other words, when used for the purpose of wiping off dirt, etc., it is possible to enhance the effect of removing dirt by using it while it is moistened with water and other detergent components. Many products are commercially available.

  For example, a typical example is a product such as a wet tissue, which contains moisture, a detergent, a disinfectant, a fragrance, and the like. However, this is wet-processed in a pre-manufacturing stage and enclosed in a package for preventing dryness, and is immediately dried when removed from the package.

In other words, it is common sense to use cloth-like materials moistened with liquids such as water and other chemicals depending on the purpose, but for that purpose, it can be moistened on the spot where it is actually used, It is natural to use a package that has been pre-moistened and packaged.
Moreover, the following is found as literature regarding such a technique.
