Description

  The present invention relates to a method for washing and sterilizing a towel.

  Conventionally, as a method for cleaning and sterilizing a wet towel, a method of cleaning and sterilizing using sodium hypochlorite and strong alkaline water (Patent No. 3163401, "Disinfecting and cleaning apparatus for cleaning wet towel and towel" [Reference 1]) Alternatively, a method of immersing in an aqueous photocatalyst functional material coating (Japanese Patent Application Laid-Open No. 2001-259546 “Washing towel and cleaning method thereof” [Document 2]) or a method of cleaning with strong alkaline functional water (Japanese Patent Laid-Open No. 10-33642 “Lending”). "Wet towel washing method" [Reference 3]). However, both are cleaning and sterilization methods using conventional chemicals (medicine), and it is possible to reliably remove stubborn dirt that wipes off a table, a stove, a top plate, etc. attached to a towel. It seems difficult. In particular, the use of these chemicals is not considered sufficient to remove dirt adhering to the corners and / or seams of the towel.

  On the other hand, as a document to ensure the whiteness of the hand towel and the cleaning effect, a whiteness improving agent for washing a wet towel comprising at least one aluminum compound selected from the group consisting of aluminum sulfate and double salts thereof is used at the time of rinsing. As a document for improving the finished whiteness of the hand towel and for reducing the neutralization of drainage (Japanese Patent Application Laid-Open No. 2004-277628, “Whiteness improver for washing a towel and a method for washing a towel” [Document 4]). . However, since the present invention requires that the rinsing process is performed three times in [0017] of the embodiment, the work is complicated. In principle, there is room for further improvement in order to reliably remove stubborn dirt, which is an acid treatment. And although alum is used and sterilization and a refreshing feeling are fostered, it is harmless, but the effect is not necessarily considered sufficient.

Rinse while washing. This second rinse is approximately 3 minutes. The water temperature of this rinse is made into normal temperature (refer FIG. 1-4).

  Fifth, all washing and sterilization operations are completed by performing post-treatment using the dehydrator 5 and the dryer 6 (see FIGS. 1-5 to 1-6).

  Next, a second embodiment will be described based on FIGS. 2-1 to 2-6.

  The first is pre-washing. Approximately 4,000 towels 4 are stored in an aqueous solution 2 in which 500 cc of sodium hypochlorite is added to 450 l (liter) of water filled in the washing tub 1 and stirred. While pre-washing. This pre-cleaning time is approximately 3 minutes. The temperature of the aqueous solution 2 is normal temperature (see FIG. 2-1).

  The second is a main wash, in which approximately 4,000 towels 4 are stored in an aqueous solution 200 in which 500 cc of a nonionic detergent is added to 450 l (liter) of water filled in the washing tub 1 and stirred. While pre-washing. This main cleaning time is approximately 10 minutes. The temperature of this aqueous solution 200 shall be about 60 degreeC (refer FIG. 2-2).

  Fourth, in the process of transporting to the conveyor 8, an aqueous solution 201 in which 75 cc of ozone and 75 cc of magnesium chloride are added to 450 l (liter) of water is atomized through the sprayer 9 and sprayed toward the towel 4. Sterilize and / or remove dirt. In this case, since the hand towel 4 is conveyed by the conveyor 8 in the unfolded state, the sprayed aqueous solution 201 is distributed evenly and has a feature useful for sterilization and / or dirt removal. Although not shown, a second rinse may be performed. Although not shown in the figure, in order to generate ozone, one or several sealed mercury tubes are provided in a glass tube, and ozone gas is blown into the glass tube. State ozone gas) can be provided (see FIG. 2-4).

  Fifth, by performing post-treatment using the dehydrator 5 and the dryer 6, all the cleaning and sterilization operations are completed (the same as the above example).

  FIG. 3 shows the wet towel 4 unfolded before cleaning and sterilization. In some places, there is a dirt 400, and particularly, the dirt 400 adhered to the corner 401 and the stitching part 402. It is extremely difficult to drop. The situation is the hand towel 4 processed (finished) by the conventional cleaning and sterilization method shown in FIGS. 3 and 4, and the dirt 400 still remains in the corner 401 and the stitched portion 402. On the other hand, when the same dirty hand towel 4 is processed by the cleaning and sterilizing method of the present invention, almost all of it has fallen as the hand towel 4 shown in FIG. The finish. FIG. 5B shows a state where the hand towel 4 is finally finished. As mentioned above, the white finish is noticeable and cleanliness is transmitted.
