- the diet sheet 1 of the present invention is particularly suitable for cleaning a flooring, but can also be used for cleaning or polishing other hard surfaces such as a car body and leather shoes.
- “%” means “% by weight” unless otherwise specified.
- Kao Co., Ltd. “Polishing Mipet” (trade name, viscosity: 4 mPa, s at 25: 4 mPas, s) manufactured by Kao Corporation was used as a cleaning polish, and was impregnated with 144% of the weight of the liquid holding sheet.
- liquid-impermeable aluminum vapor-deposited sheet (49 xm in thickness) was used as the liquid-impermeable sheet.
- two long holes with a size of 7.5 mm wide and 210 mm long were opened in the vapor deposition sheet, and a sheet in which these long holes were previously sealed with an aluminum vapor deposition sheet with an adhesive was used.
- a liquid holding sheet impregnated with a cleaning polish was disposed between the two vapor deposition sheets, and four sides of the two vapor deposition sheets were further sealed by heat sealing. As a result, a perforated package having a size of 270 mm ⁇ 95 mm was obtained (a hole opening ratio of long holes: 12.3%).
- softwood pulp heat-shrinkable fiber polypropylene (core) / polyethylene (sheath) composite fiber
- Z thermoplastic fiber thermalally fusible polyester fiber
- Z610 0 weight Using a mixed fiber material consisting of the following ratios, a paper with a basis weight of 12 g Zm 2 and a hydrophilizing agent added in the drying step of wet papermaking is spun-pound nonwoven fabric (polyester (core) polyethylene (sheath) composite fiber)
- a sheet having a basis weight of 40 g Zm 2 was attached to the sheet, and a sheet having irregularities formed by steel match heat embossing was used.
- This surface sheet was 6.8 m / k Pa ⁇ s. Soshi
- the surface sheet and the inner layer sheet were integrated as shown in FIG. 4 to obtain a liquid sustained release sheet.
- the perforated packages were stacked so as to face the inner layer sheet of the liquid sustained-release sheet, and attached to a cleaning tool shown in FIG. 5 for cleaning. At this time, the surface of the open-packed body where the long holes were formed was opposed to the liquid sustained release sheet.
- This jet sheet had the configuration shown in FIG.
- Example 1 In place of the inner layer sheet used in Example 1, a mixed fiber raw material of softwood craft pulpno thermoplastic thermoplastic fiber (heat-fusible polyester fiber) -90Z10 (weight ratio) was used. beaten used was superposed 2 sheets of paper having a basis weight of 3 0 gZm 2 obtained by be relocated papermaking conditions such Shime ⁇ as the inner layer sheet. This inner layer sheet is not irregularly shaped. The air permeability of this inner layer sheet was 0.7 mZkPa ⁇ s. Except for this, an jet sheet was obtained in the same manner as in Example 1.
- Example 1 a fiber material consisting of 100% softwood pulp was used, and the basis weight obtained by changing the papermaking conditions such as beating and wet pressure in Example 1 was used. Stack two sheets of paper with an amount of 40 gZm 2 was used as the inner layer sheet. This inner layer sheet is not irregularly shaped. The air permeability of this inner layer sheet was 5.3 m / kPas. Except for this, an diet sheet was obtained in the same manner as in Example 1.
- a wet sheet was obtained in the same manner as in Example 1 except that the inner sheet was not used.
- the liquid sustained release sheet in this comparative example is a single sheet (single ply).
- Example 1 Instead of forming long holes in the aluminum vapor-deposited sheet in Example 1, a large number of circular holes having a diameter of l mm were regularly formed so that the hole ratio became 0.018%. No inner sheet was used. Except for these, an edge sheet was obtained in the same manner as in Example 1.
- the wet sheet obtained in each of the examples and comparative examples was attached to a quickle wiper manufactured by Kao Corporation, and the flooring (Peditile F type KER525F manufactured by Matsushita Electric Works) was continuously wiped. The amount of liquid released into the sample was measured. Each time one tatami mat was wiped, the wet sheet was removed from the cleaning section head, and its weight was measured to calculate the amount of liquid released.
- the stroke of wiping one round trip at a distance of about 90 cm is defined as one stroke, and this movement is performed in two rows in the longitudinal direction (180 cm) and four rows in the short direction (90 cm) of one tatami mat. Cleaning of tatami mats is completed. [Finishability]
- the evaluation criteria are as follows.
- the release amount of the cleaning agent is too large, especially when a polishing agent is applied, the gloss at the initial stage of cleaning becomes too high as compared with the final stage of cleaning, and the unevenness of the gloss becomes remarkable depending on the applied location, which is not preferable.
- the release amount is too large, the drying time of the polishing agent will be delayed.
- the release amount of the cleaning agent is too small, the surface to be cleaned will not be uniformly wetted, and uneven gloss will occur particularly when a polishing agent is used. Therefore, the evaluation was made based on the following criteria, taking into account the difference in the finish due to the amount of release.
- the coating is non-uniform, high gloss and low gloss are present, and the gloss is non-uniform.
- the ⁇ ⁇ ⁇ et sheet of the example has a sufficient amount of liquid discharged even after cleaning up to the seventh tatami mat. It can be seen that the decrease in the amount of liquid released is small. It also shows that the finish after cleaning is good. On the other hand, in the case of the jet sheet of Comparative Example 1, since the application amount of the first tatami was too large, the gloss became partially higher than that of the second tatami and thereafter, resulting in uneven gloss. Also, it can be seen that the amount of discharged liquid is so large that it cannot be cleaned up to the 7th tatami mat.
- the cleaning jet sheet of this invention a large amount of cleaning agents and polishing agents are stably and uniformly discharged over a wide range of surfaces to be cleaned, such as a floor, from the beginning to the end of cleaning.
- a polishing agent when used, the entire surface to be cleaned can be uniformly glossed.
