Drawings
Fig. 1 is a plan view showing a cleaning wet sheet according to an embodiment of the present invention.
Detailed Description
Hereinafter, a cleaning wet sheet 100 according to an embodiment of the present invention will be described with reference to the drawings. The technical scope of the present invention is not limited to the examples of the figures.
In the present specification, the numerical range described in "to" includes the numerical values described before and after "as the lower limit value and the upper limit value.
[ Description of 1 Structure ]
First, the structure of the cleaning wet sheet 100 will be described.
As shown in fig. 1, the cleaning wet sheet 100 is a sheet obtained by impregnating a rectangular raw paper sheet 1 with a chemical solution 2. Here, the base paper sheet refers to a state before the cleaning wet sheet is impregnated with the chemical solution.
[ (1) Raw paper sheet ]
The base paper sheet 1 is a nonwoven fabric produced by combining predetermined fibers by known techniques such as hydroentanglement, hot air, air-laying, spot bonding, spunbonding, and needle punching. Particularly preferred is a nonwoven fabric produced by a hydroentanglement method.
Specifically, as the base paper sheet, for example, a nonwoven fabric produced by mixing hydrophilic fibers with hydrophobic fibers and then bonding these fibers is used.
[ A hydrophilic fiber ]
As the hydrophilic fiber, natural fibers such as cotton, pulp, hemp, etc., regenerated fibers such as rayon, ketoamine fibers, etc., may be used, but from the viewpoint of maintaining water retention, pulp, rayon, polypropylene spunbond fibers (PPSB), etc., are preferably used.
The proportion of the hydrophilic fibers in the fibers constituting the base paper sheet is preferably 40 to 80% by mass.
[ B hydrophobic fiber ]
Examples of the hydrophobic fibers include polyolefin fibers such as Polyethylene (PE), polypropylene (PP), and polyvinyl alcohol, polyester fibers such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), and acrylic fibers, and these fibers may be used alone or in combination of two or more. Examples of the two or more kinds of composite fibers include a core-sheath type in which a resin having a relatively low melting point (low melting point resin) is used as a sheath portion and a resin having a relatively high melting point (high melting point resin) is used as a core portion, a side back type in which a low melting point resin and a high melting point resin are juxtaposed in a predetermined direction, and the like (side back).
The blending ratio of the hydrophobic fibers among the fibers constituting the base paper sheet is preferably 20 to 60% by mass.
[ Weight per unit area ]
From the viewpoint of both the dirt holding ability and the sheet softness, the basis weight of the base paper sheet is preferably 50 to 100g/m 2. The weight per unit area is in accordance with JIS P8124:2011 (same applies hereinafter).
[d CNF]
Cellulose Nanofibers (CNF) may be added to the base paper sheet.
CNF is a fine cellulose fiber obtained by defibrating pulp fibers, and generally refers to a cellulose fiber containing cellulose fine fibers having a fiber width of nanometer size (1 nm to 1000 nm), preferably a fiber having an average fiber width of 100nm or less. For example, a number average, a median, a mode diameter (mode) and the like of a predetermined value are used for calculation of the average fiber width.
The CNF may be impregnated uniformly in the thickness direction of the base paper sheet, but it is preferable that the content of CNF gradually increases from the center in the thickness direction of the base paper sheet toward the front and back surfaces. Thus, the cleaning sheet 100 is not easily broken even when the cleaning surface is strongly rubbed.
[ (A) pulp fiber capable of being used for CNF ]
Examples of pulp fibers that can be used for producing CNF include mechanical pulp such as hardwood pulp (LBKP), conifer pulp (NBKP), bleached thermo-mechanical pulp (BTMP), millboard pulp (SGP), pressboard (PGW), refined millboard pulp (RGP), chemical millboard pulp (CGP), thermowood pulp (TGP), crushed wood pulp (GP), thermomechanical pulp (TMP), chemical thermomechanical pulp (CTMP), and disc-milling mechanical pulp (RMP), and deinked pulp (DIP) produced from brown waste paper, waste kraft envelopes, waste magazines, waste newspapers, waste handpieces, office waste paper, waste corrugated paper, white waste paper such as waste kent waste paper, imitation waste paper, ground waste paper, low-grade printing waste paper, and the like. They may be used alone or in combination of plural kinds as long as the effects of the present invention are not impaired.
[ (B) method of defibration of CNF ]
Examples of the defibration method for producing CNF include mechanical methods such as a high-pressure homogenizer method, a microfluidizer method, a mill grinding method, a bead mill freeze-pulverizing method, and an ultrasonic defibration method, but are not limited to these methods.
The CNF subjected to only mechanical treatment (not modified) by the above-described defibration method or the like, that is, the CNF not modified with a functional group, has high thermal stability as compared with the CNF modified with a functional group such as a phosphate group or a carboxymethyl group, and thus can be used for a wider range of applications, but the CNF modified with a functional group such as a phosphate group or a carboxymethyl group can also be used for the present invention.
For example, CNF obtained by subjecting pulp fibers to a mechanical defibration treatment may be subjected to a chemical treatment such as carboxymethylation or an enzymatic treatment. Examples of chemically treated CNF include TEMPO oxidized CNF, phosphorylated CNF, and phosphitylated CNF, etc., of iCNF (individualized CNF) (monocellulose) having a diameter of 3nm to 4 nm.
The CNF may be a CNF subjected to chemical treatment or enzymatic treatment alone, or a CNF subjected to mechanical defibration treatment.
[ E embossing ]
As shown in fig. 1, the base paper sheet 1 is provided with embossments 11 which are portions in which the sheet is compressed in the thickness direction and in which irregularities are formed, in order to improve the wiping performance against dirt on the surface to be cleaned.
The embossments 11 include a convex embossment 111 protruding toward one side of the sheet and a concave embossment 112 protruding toward the other side of the sheet (concave toward one side), which are arranged in a staggered arrangement with each other.
The embossments 111 and the embossments 112 are each formed in a so-called gourd shape having a substantially elliptical shape in a plan view of the base paper sheet 1 and having a necked portion in a substantially central portion in the longitudinal direction.
The arrangement and shape of the embossments are preferably the above arrangement and shape from the viewpoint of sufficiently improving the wiping performance of both surfaces of the cleaning wet sheet 100, but the present invention is not limited thereto and may be appropriately modified. Although not preferable, a planar base paper sheet having no embossment may be used.
[ (2) Liquid medicine ]
As the chemical solution 2 impregnated in the raw paper sheet 1 as described above, a chemical solution containing a betaine compound can be used. The content of the betaine compound in the chemical solution is preferably 0.40 to 1.50 mass%.
Betaine compounds are compounds having positive and negative charges at non-adjacent positions in the same molecule, having no dissociable hydrogen bonded to the atom having the positive charge, and having no charge on the whole molecule, and include glycine betaines such as trimethylglycine and imidazole betaines.
The chemical solution 2 is weakly alkaline having a hydrogen ion index (pH) of 8.00 to 9.00, preferably a chemical solution containing 5.00 to 15.00 mass% of ethanol, and more preferably a chemical solution containing 8.00 to 12.00 mass% of ethanol. The other component of the chemical solution 2 is purified water.
The chemical solution 2 is preferably impregnated by 150 to 450 mass% and more preferably by 180 to 350 mass% with respect to the mass of the base paper sheet 1 at the time of drying.
The ratio of the mass of the impregnated chemical solution to the mass of the base paper sheet at the time of drying is referred to as the chemical solution impregnation rate.
The chemical solution is impregnated into the dried base paper sheet and released from the cleaning surface when the cleaning wet sheet 100 is used.
[ Description of Effect ]
According to the cleaning wet sheet 100 of the present embodiment, a chemical solution containing a betaine compound is used as the chemical solution 2 impregnated in the raw paper sheet 1.
The betaine compound has a deodorizing effect on malodor components such as ammonia, hydrogen sulfide, methyl mercaptan, and trimethylamine that are easily generated from kitchen waste, and therefore, by discarding the cleaning wet sheet 100 into a trash can, a trash bag, or the like after cleaning use, malodor generated from kitchen waste discarded in the same trash can, trash bag, or the like can be reduced.
Further, the chemical solution 2 contains 0.40 to 1.50 mass% of the betaine compound, whereby an increase in cost is suppressed and a sufficient deodorizing effect is easily exhibited.
That is, if the content of the betaine compound is less than 0.40 mass%, it is difficult to exert the deodorizing effect on the malodor components easily generated from the kitchen waste as described above, and, in comparison with the case where the content of the betaine compound is more than 1.50 mass%, the deodorizing effect is not changed from 1.50 mass%, and only the cost is increased.
According to the cleaning wet sheet 100 of the present embodiment, as the chemical liquid 2 impregnated in the raw paper sheet 1, a chemical liquid having a weak basicity with a hydrogen ion index (pH) of 8.00 to 9.00 and containing 5.00 to 15.00 mass% of ethanol is used.
Thus, the oil stain can be floated due to the high content of ethanol, and the cleaning performance for the oil stain and the liquid stain can be improved while suppressing the deterioration rate of the cleaning surface by drying quickly and having a pH of 9.00 or less, thereby suppressing the possibility of damaging the cleaning surface.
[ Modification example ]
A modification of the above embodiment will be described below.
The drug solution 2 may further contain polyoxyethylene Alkyl Ether (AE). When the drug solution 2 contains polyoxyethylene alkyl ether, the content thereof is preferably 0.05 to 0.15 mass%.
By adding polyoxyethylene alkyl ether to the chemical solution 2, the wiping performance against oil stains and liquid dirt can be further improved.
The chemical solution 2 may further contain a degerming agent such as benzalkonium chloride. When the chemical solution 2 contains benzalkonium chloride as the degerming agent, the content thereof is preferably 0.05 to 0.20 mass%.
The liquid medicine 2 contains a sterilizing agent such as benzalkonium chloride, thereby improving the sterilizing ability of the cleaning wet sheet 100 and the storability of the cleaning wet sheet 100.
Examples
Next, the results obtained by evaluating the examples and comparative examples of the present invention will be described. Hereinafter, the present invention will be specifically described with reference to examples, but the present invention is not limited to these examples.

First, a description will be given of the result of how much the liquid medicine impregnation rate of the cleaning wet sheet is reduced by the cleaning in the kitchen.
[ (1) Sample preparation ]
The following cleaning wet sheet was produced.
[ A raw paper sheet ]
As a base paper sheet, a nonwoven fabric (rectangle having a long side of 300mm and a short side of 200 mm) having a weight per unit area of 60g/m 2 and being composed of 40 mass% of PET fibers, 40 mass% of rayon fibers, and 20 mass% of PP/PE adhesive and being bonded by hydroentanglement was used. Note that embossing is not performed. The mass at the time of drying was 3.86g.
[ B liquid medicine ]
As the liquid medicine impregnated in the raw paper sheet, a liquid medicine containing 0.50 mass% of betaine compound and 10.00 mass% of ethanol (the remainder being purified water) was used. The mass of the impregnated medicinal liquid is 9.90g. As betaine compounds, epoleon N-300 and Epoleon OS-660 (both manufactured by Co., ltd.) were used as the compounds 1:1, and mixing the materials according to the proportion.
[ (2) Test content ]
The following test was performed using the cleaning wet sheet of the above sample. 10 times of the same test were performed, and an average value was calculated.
[ Procedure 1]
The wet cleaning sheet of the sample was placed in a sealed bag and allowed to stand for 24 hours.
[ Step 2]
The mass of the wet cleaning sheet obtained in step 1 was measured.
[ Step 3]
The cleaning wet sheet subjected to step 1 was used to clean an area of 0.8m 2. Specifically, the cleaning wet sheet was placed on a table (material: polypropylene) having an area of 0.8m 2 with one side facing upward, a weight (mass 1000g, rectangular parallelepiped having a long side of 250mm and a short side of 100 mm) was placed thereon, and then the entire surface of the table was wiped at one time.
[ Step 4]
The cleaning wet sheet subjected to step 3 was used to clean the area of 0.8m 2 again. The method is the same as in step 3, but the cleaning wet sheet is turned over (with the upward side in step 3 facing down).
[ Step 5]
The mass of the wet cleaning sheet obtained in step 4 was measured.
[ (3) Test results ]
The results of the test are shown in table I. The numerical values are all average values of 10 tests.
TABLE 1
TABLE I
[ (4) Evaluation ]
The impregnation rate of the chemical solution measured in step 2 was calculated from the mass of the base paper sheet and the mass of the wet sheet before cleaning, and found to be about 253%.
The liquid medicine impregnation rate at the time of measurement in step 5 was calculated from the mass of the base paper sheet and the mass of the wet sheet after cleaning, and was about 171%.
Further, the area to be wiped at the time of ordinary kitchen cleaning is assumed to be about 1.6m 2 from the area of 0.65m×2.55 m= 1.6575m 2 in the horizontal direction, and if the cleaning areas in the above-described step 3 and step 4 are combined, the area to be wiped at the time of ordinary kitchen cleaning is matched.
Based on these results, it is assumed that the reduction rate of the liquid medicine impregnation rate of the cleaning wet sheet at the time of general kitchen cleaning is about 253% to 171% ≡80%.
[2 Test 2: quality verification 1 (deodorization test by detection tube method)
The following test is used to explain the results of evaluating the presence or absence of the difference in deodorizing performance caused by the betaine compound.
[ (1) Sample preparation ]
Cleaning wet sheets of the following examples and comparative examples were produced.
[ Example (a) ]
The same base paper sheet as in test 1 was impregnated with 7.70g of the same chemical solution as in test 1. In this case, the liquid medicine impregnation rate was about 200%. This value assumes a state in which a cleaning wet sheet having a drug solution impregnation rate of 300% is used for kitchen cleaning and the drug solution impregnation rate is reduced by 100%.
The state in which the liquid medicine impregnation rate was reduced by 100% was obtained by reserving the remaining amount of 20% in response to the reduction rate being greater than the assumed case, based on the results of test 1 in which the reduction rate of the liquid medicine impregnation rate of the cleaning wet sheet at the time of general kitchen cleaning was about 80%.
Comparative example
In the same raw paper sheet as in test 1, 7.70g of a chemical solution (ethanol 10.00 mass% and purified water as the remainder) from which the betaine compound was removed from the same chemical solution as in test 1 was impregnated in the same manner as in example. In this case, the liquid medicine impregnation rate was the same as in example.
[ (2) Test content ]
The cleaning wet sheet of the above examples and comparative examples was used to carry out a deodorizing test according to the test tube method described in the deodorizing test according to the standard for fiber product authentication of the society for human fiber evaluation technology SEK mark (revised edition of 2022, month 4, and day 1). Wherein the odor components are 4 kinds of ammonia, hydrogen sulfide, methyl mercaptan and trimethylamine as main components of odor of kitchen waste, the initial concentrations are 100ppm of ammonia, 4ppm of hydrogen sulfide, 8ppm of methyl mercaptan and 28ppm of trimethylamine, the capacity of the container is 5L, and the measurement time (standing time) is 1 hour.
[ (3) Test results ]
The results of the test are shown in table II.
TABLE 2
Table Il
[ (4) Evaluation ]
If the test results of the examples are compared with those of the comparative examples, the reduction rates of hydrogen sulfide and methyl mercaptan, which are low in the comparative examples, are greatly improved in the examples. It is thus found that the deodorizing effect against the odor of kitchen waste can be improved by adding the betaine compound to the cleaning wet sheet.
Although the reduction rates of ammonia and trimethylamine were slightly lower in the examples, they were high in any case and were only within the range of errors, and therefore, it was important to greatly improve the reduction rates of substances such as hydrogen sulfide and methyl mercaptan which were difficult to remove.
[3 ] Test 3: quality verification 2 (deodorization test based on sensory evaluation) ]
The following test is used to explain the results of evaluating the presence or absence of the difference in deodorizing ability caused by the betaine compound.
[ (1) Sample preparation ]
Cleaning wet sheets of the same examples and comparative examples as in test 2 were produced.
[ (2) Test content ]
The following test was performed using the cleaning wet sheet of the above sample.
[ Procedure 1]
Kitchen waste is produced according to a manual of an aromatic deodorizing and deodorizing agent society. Specifically, beef, green Chinese onion, eggshell and carrot were cut into equal amounts and cured at 35℃for 72 hours.
[ Step 2]
The odor generated by the kitchen waste generated in step 1 was adjusted to have an odor intensity of 4, and the odor was placed in a closed container having a capacity of 5L together with the cleaning wet sheet of the example or the comparative example. A container in which the cleaning wet sheet was not placed was prepared.
[ Step 3]
After 72 hours from the step 2, the odor was confirmed by 5 judges by opening each bag, and the odor was evaluated in 6 grades (5 to 0 in order from the intensity of the odor), and the average value was calculated.
[ (3) Test results ]
The results of the test are shown in table III.
TABLE 3
Table III
| Evaluation average | |
| Examples | 0.2 |
| Comparative example | 1.2 |
| Sheet-free | 3.5 |
[ (4) Evaluation ]
In contrast to the comparative example, which had an average value of 3.5 to 1.2=2.3 when compared with the test result of the comparative example, which had an average value of 3.5 to 0.2=3.3 when compared with the test result of the comparative example, which had an average value of 1 minute when compared with the test result of the comparative example, the test result of the example was compared with the test result of the comparative example, which had an average value of 3.5 to 1.2=2.3 when compared with the test result of the comparative example.
It is thus found that the deodorizing effect against the odor of kitchen waste can be improved by adding the betaine compound to the cleaning wet sheet.
[4 Test 4: quality verification 3 (deodorant comparison)
The results of evaluating the differences in deodorizing performance of the respective deodorants are described by the following tests.
[ (1) Sample preparation ]
Cleaning wet sheets of the following examples and comparative examples were produced.
[ Example (a) ]
The same as in the example of test 2.
Comparative example 1
In the same raw paper sheet as in example, 7.70g of a medicinal liquid obtained by replacing a betaine compound with a green tea dry distillation extract (green tea dry distillation extract 0.50 mass%, ethanol 10.00 mass%, and other components were purified water) was impregnated in the same manner as in example. In this case, the liquid medicine impregnation rate was the same as in example.
Comparative example 2
The same raw paper sheet as in example was impregnated with 7.70g of a chemical solution obtained by substituting a betaine compound for persimmon tannin from the same chemical solution as in example (0.50% by mass of persimmon tannin, 10.00% by mass of ethanol, and purified water as the other component) in the same manner as in example. In this case, the liquid medicine impregnation rate was the same as in example.
[ (2) Test content ]
The cleaning wet sheets of the above examples and comparative examples were used to carry out the test in the same manner as in test 2. Wherein the capacity of the container was 45L.
[ (3) Test results ]
The results of the test are shown in table IV.
TABLE 4
Table IV
[ (4) Evaluation ]
When the test results of examples are compared with those of comparative examples 1 and 2, the hydrogen sulfide reduction rate, which is low in the comparative examples 1 and 2, is greatly improved in the examples. Similarly, in comparative examples 1 and 2, the reduction rate of methyl mercaptan was slightly increased in examples. From these deodorizing agents, it is found that betaine compounds have the most deodorizing effect on the odor of kitchen wastes.
Although no significant difference was observed between the reduction rates of ammonia and trimethylamine, it was important that the reduction rate of substances such as hydrogen sulfide which were difficult to remove was significantly higher than those of the other two substances in the examples, and that the reduction rate of methyl mercaptan which was similarly difficult to remove was also excellent.
