A liquid synthetic component or mixture capable of absorbing a portion of at least 200% of its dry weight Inability to liberate or salt out insoluble solid materials that do not dissolve in any of the components of the product. and.

Materials that satisfy these conditions are nonwoven materials obtained by wet or dry processing. Non-fuzz hides such as linear structures and other cellulose structures. It is preferable to choose from lofilik woven materials.

When used in the present invention, those materials have a surface density of at least 209/d. It is preferable to

These conditions depend on the nature of the impregnated synthetic components and the impregnated synthetic components that are retained by the substrate. It is equally related to the amount of ingredients. The above values are the maximum water absorption percentage of the dry substrate. It is expressed as

The purpose of the present invention is to achieve aqueous synthesis up to an impregnation level not exceeding 50% of this maximum absorption capacity. wet or Surface cleaning containing hydrophilic woven or non-woven materials obtained by dry processing, or To provide a disposable impregnated wipe for maintenance. The wiping material is characterized by the following: That is, the aqueous synthetic component is in the form of an aqueous solution and contains the following components: including, i.e. at least one water in a proportion of at least 4% of the total weight of the aqueous synthetic components by weight; a miscible solvent and an amount of at least one solvent sufficient to bring the solution to an acidic pH. Contains organic acid or organic acid.

This pH is preferably 2 to 5, most preferably 3.5 to 3.8.

Inorganic or organic acids are hydrophilic materials, especially acetic acid, citric acid, and maleic acid. , phosphoric acid, or an acid that does not physically or chemically act on alkyl sulfonic acids. selected from.

Each solvent that is miscible with water is a volatile solvent that emits a vapor pressure at 20°C and 13 Pa, especially 1 Alcohols containing ~4 carbon atoms such as methanol, ethanol, inpropanol tools, butanol, glycols, glycol ethers containing 2 to 8 carbon atoms especially monoethylene glycol butyl ether and volatile silicones, especially pc 344 (Dow Corning).

According to one preferred feature, the impregnation level is adjusted strictly according to the nature of the absorbent material. between 5 and 35% of the maximum absorbent capacity of the absorbent material in the dry state.

According to another preferred feature, the water-miscible solvent comprises a total weight of said aqueous solvent. It is present at a level of 5-40% by weight.

Another characteristic is that aqueous solvents contain, among other things, small amounts of ionic and nonionic , or amphoteric surfactants and small amounts selected from fungicides, perfumes, colorants and preservatives. containing at least one product of.

The following example, given as an illustrative and non-limiting example, is a wipe according to the invention. Immediately Chi, Example ■ A non-woven material supplied by a French non-woven material manufacturer under the name 2406 (hereinafter the letter A) 359/rIt was used.

It is a mixture of cellulose, cotton, and polyester with an acrylic vinyl binder with a proportion of 75% fiber and 25% binder (in the wet process). This material The material has a water absorption capacity of <1259/l.

This material of (30X303) square contains 3597d of aqueous synthetic components with the following formula: (approximately 25% of maximum absorption). That is, Monoethylene glycol butyl ether 8% weight ethanol (95%) 10% formaldehyde (30%) 0.1 % Acetic acid (100%) 0.1% Water 81.8% pH= 3.7 Impregnation involves adding the above-mentioned absorption to the noble synthetic component (25% by weight) corresponding to the impregnation level mentioned above. This is done by bringing the materials into contact.

The cleaning efficacy of the absorbent material was tested in the following manner.

That is, fatty dirt components include lard, margarine, carbon black, and ferrous oxide. , prepared from ferric oxide. Add 0.049 of this synthetic component to a black glass plate (30X 40 crM).

Move the dirty glass regularly in this way, alternating from top to bottom and then from left to right for 1 minute. I moved it to wipe it. The results were evaluated by a group of 15 people skilled in this type of evaluation. People visually evaluated the items and gave them scores on a scale of 0 to 5.

0 = very bad. There are many marks.

1-Bad 3 = acceptable 4=Okay 5=Excellent. No trace.

Table 1 below compares the same nonwoven material with different impregnation levels. The average of the results obtained is shown for comparison.

This table shows that if the impregnation level is 25%, the score is 5 and there is no mark on the black glass. This indicates that the results are excellent.

Example 2 It was the same as Example 1 except that the nonwoven material was different.

The nonwoven material used here (hereinafter referred to as B) was manufactured by Nurley with a ppv of 3000. It is commercially available with a density of 309/lri and a maximum water absorption level of 1 829/lf, obtained by dry process, polypropylene without binder and vinyl It is made from a 100% mixture of scose.

The nonwoven material used here (hereinafter referred to as C) was purchased from Kaisersbar Company from Homecel ( HOMECEL) 90, with a maximum water absorption of 8809/d. 20% acrylic binder and 80% It was made from cellulose fiber.

Table 2 shows the results obtained for comparison with the results of Example 1.

According to this table, in the case of nonwoven material B, when the impregnation level is 10%, it is considered to be good or excellent. In the case of nonwoven material C, excellent results were obtained when the impregnation level was 35%. Example 1 and Example 2 were the same except that the nonwoven material was different.

The nonwoven material used here (hereinafter referred to as ``Li'') is commercially available as 4175 from Nurley Company. It has a density of 509/rIt, a maximum water absorption capacity of 4659/d, and a Made from 0% cotton and viscose fibers and 30% acrylic binder, obtained by dry process. It was.

The nonwoven material used here (hereinafter referred to as E) was manufactured by a French nonwoven material manufacturing company called 2426 It has a density of 559/rrl and its maximum water absorption capacity. is 1799/m with 75% cellulose/polyester fiber and 25% It was made with an acrylic/vinyl binder and was obtained by a wet process.

The nonwoven material used here (hereinafter referred to as F) was manufactured by a French nonwoven material manufacturing company using 1140. It has a density of 45g/- and its maximum water absorption capacity is 1609/ld with 50cX cotton fiber, 30% viscose fiber and 20% viscose fiber. % of acrylic binder and was obtained by wet process.

Table (2) shows the results obtained for comparison with the results of the first example. This table is non-woven For lumber, an impregnation level of 10% gave almost excellent results (rating 4.8). However, in the case of nonwoven materials E and F, when the impregnation level was set to 25%, the evaluation was excellent. This shows that the results obtained are as follows.

Example 3 Here, the same nonwoven material as in Example 1 was used.

Impregnation was carried out with the following synthetic components: That is, monoethylene glycol butyl ether Tel 8% weight ethanol (95%) 10X foam Aldehyde (30%) o, i% sodium sulfate low reel Ether 0.2% Sodium alkyl sulfate 0.4% water 81.3% The pH is 5 because a technical surfactant containing some acid was used. See the results The numbers are shown in the table.

Results between good and excellent occurred when the impregnation level was 25%. this is This was slightly lower than the excellent result of Example 1.

Example 4 Aqueous solutions for impregnation were prepared in various formulations and are shown in Table 2.

Formulas 1-8 were prepared according to the invention using acid pH.

Formulas 9-11 were prepared at non-acidic pH and, due to that fact, do not form part of the present invention. It's a good thing.

Nonwoven material A of Example 1 was prepared at various levels using one of formulas 1 to 11 once and for all. Impregnation was performed with

Table 7 shows the results obtained.

Between acceptable and excellent acid pH of wipes impregnated with formulas 1-8 produce the results to be evaluated, to which no acid is added and the pH is between 7.1 and 7.3. It is surprising that formulas 9 to 11 showed results that were evaluated as inadequate. This is something that should be done.

According to Tables II and V, it is even more surprising that the pH is between 3.5 and 3.8. The formula used gave good results and excellent results.

From the test of Example 1, it was found that It was possible to determine the maximum efficacy conditions for the impregnated wipes according to the invention.

These wipes prevent unwanted evaporation of the solvent when it is commercially available. It will be understood that the product is packaged in a hermetically sealed container.
