Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry sheet used for absorbing moisture of plants such as flowers and leaves during the production of pressed flowers.

[0002]

2. Description of the Related Art Conventionally, as a dry sheet used in the production of pressed flowers, a sheet that has been dipped in an aqueous solution of calcium chloride and then dried has been used. In other words, although only calcium chloride was used as a desiccant, calcium chloride has a strong hygroscopic force, but on the other hand, it tends to cause deliquescent due to moisture absorption. There was a problem that it became damp. Although it is necessary to dry the plants as quickly as possible to finish the pressed flowers freshly, the conventional sheets had a low maximum moisture absorption and were susceptible to stuffiness. Since the stuffed sheet loses almost all its hygroscopicity, it is difficult to produce fresh pressed flowers, and when the sheet gets stuffed, its moisture reversely wets the plants on the sheet, and It was a cause of discoloration and fading.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a dry sheet having a large maximum moisture absorption amount, which is excellent in moisture absorption capability, particularly initial moisture absorption capability immediately after the start of moisture absorption, and which is resistant to stuffiness due to moisture absorption.

[0004]

Means for Solving the Problems The gist of the present invention which has solved the above problems is as follows: 1) A dry sheet for producing pressed flowers, in which calcium chloride and magnesium chloride are mixed in a weight ratio of 2: 1 to 3: 1. A water absorbent sheet material is immersed in an aqueous solution containing solute as a solute, and the sheet material is dried at a high temperature of 95 ° C. to 115 ° C. to obtain a pressed flower manufacturing dry sheet.

[0005]

The dry sheet according to the present invention is prepared by immersing a water-absorbent sheet material in an aqueous solution containing a mixture of calcium chloride and magnesium chloride in a weight ratio of 2: 1 to 3: 1. Is dried at a high temperature of 95 ° C to 115 ° C, and calcium chloride and magnesium chloride are mixed on the surface and inside of the sheet, and as a drying sheet having a double hygroscopic effect by the desiccant and the sheet. To work. By mixing calcium chloride and magnesium chloride, the characteristics of calcium chloride and magnesium chloride are utilized to make a dry sheet suitable for pressed flowers. That is,
It has excellent initial hygroscopicity, has a large maximum moisture absorption, and is resistant to stuffiness, so plants are dried quickly.

[0006]

【Example】

First Example (See Table 1) Calcium chloride and magnesium chloride 2: 1, 7: 3,
And solutes mixed in a weight ratio of 3: 1 3
A total of 4 types of aqueous solutions (concentration is 30% by weight) and 30% by weight aqueous solution containing only calcium chloride as a solute.
Three types of sheets according to the present invention and one type of conventional sheet obtained by making different types of aqueous solutions, immersing the same size of paper in the same size, and immersing the same in the sun and drying at 95 ° C. Were compared. The results are shown in Table 1.

[Table 1] The initial moisture absorption of the sheet according to the present invention is increased as compared with the conventional sheet.

Second Example (See Table 2) A 30 wt% aqueous solution containing a mixture of calcium chloride and magnesium chloride in a weight ratio of 7: 3 as a solute was prepared, and zara paper immersed in the aqueous solution was used. 110 ° C after sun drying
The sheet according to the present invention obtained by drying at a high temperature and the sheet of the same size and the same material immersed in a 30 wt% concentration aqueous solution containing only calcium chloride as a solute were dried in the sun and dried at 95 ° C. The sheet was compared with a conventional sheet. The hygroscopic force and the maximum hygroscopic amount of the sheet according to the present invention were increased especially in the initial stage of hygroscopicity. Further, while the sheet of the present invention has a hygroscopic force even after 12.5 hours have passed, the conventional sheet has already lost the hygroscopic force and the sheet is stuffy. That is, the sheet of the present invention was less likely to cause stuffiness.

[Table 2]

In each of the above embodiments, paper was used as the sheet material, but it goes without saying that not only synthetic paper, Japanese paper, but also cloth can be used. Further, the drying temperature of the sheet material is preferably 95 ° C. to 115 ° C., and if it is dried at a high temperature of 120 ° C. or higher, the water absorption capacity deteriorates.

An example of using the dry sheet according to the present invention is shown in FIG. By stacking a plurality of urethane sponge 1, dry sheet 2, bung paper 3, and plant body 4 in this order, sealing them with a vinyl bag 5 or the like, and pressing with a pressure plate 6 or the like, the moisture contained in the plant body 4 is removed. The dry sheet 2 is made to absorb water.

[0010]

As described above, the dry sheet according to the present invention has an excellent hygroscopic force in the early stage of moisture absorption, so that it rapidly absorbs water from plants such as flowers and leaves, and finishes pressed flowers into a fresh primary color. You can Furthermore, since the sheet does not easily get damp, it is possible to manufacture a pressed flower that retains the fresh color of a fresh flower without discoloring or fading the pressed flower.
