Description

[Technical Field]

[0001] The present invention relates to a disinfection package in which a nonwoven fabric roll, which is made by winding a nonwoven fabric into a roll and contained in a container, is immersed in a disinfectant solution in the container so that the nonwoven fabric can be used as a disinfectant wiper, and to a nonwoven fabric for forming the nonwoven fabric roll. [Background technology]

[0002] Disinfecting wipes are typically made of nonwoven fabric impregnated with an aqueous solution with disinfecting properties (hereinafter referred to as "disinfectant") and are used disposably in environments where hygiene is important, such as hospitals and nursing homes, to wipe and disinfect various areas that people touch, such as doorknobs, handrails, dialysis machines, exteriors, and accessories, which can be routes of infection for viruses and bacteria. This can prevent infection within the hospital and the formation of clusters due to nosocomial infection, for example in a hospital.

[0003] The characteristics required for disinfecting wipes used for such purposes include: (1) since one of the purposes is to disinfect, the disinfectant solution impregnated in the nonwoven fabric must be efficiently distributed from the nonwoven fabric to the object being wiped, thereby achieving an appropriate disinfecting effect; (2) the nonwoven fabric must be able to retain sufficient disinfectant solution so that a single wipe can be used to wipe a wider area and maintain a moist state that can fully exert a disinfecting effect against viruses, bacteria, etc.; (3) since it is a cleaning wiper, it must have excellent wiping performance; and (4) since it is disposable, it must be able to be manufactured inexpensively.

[0004] As shown in Non-Patent Document 1, for example, a conventional disinfection package includes a nonwoven fabric roll formed by winding a long nonwoven fabric into a roll, a container for storing the nonwoven fabric roll, and a lid having an outlet for the nonwoven fabric and detachably attached to the container so as to seal the nonwoven fabric roll.

[0005] The disinfectant wipers in this disinfectant package include ones suitable for wiping doorknobs, toilet bowls, bed rails, etc., as well as ones suitable for wiping dialysis equipment, exteriors, accessories, etc. Two types of disinfectant are provided depending on the area where the disinfectant wipes are to be used. These two types of disinfectant are available in pink color and clear color to enhance the identification of the area where they are to be used.

[0006] The disinfectant solution used to soak the nonwoven fabric roll in the container of this disinfectant package is made by dissolving a chlorine-based agent in water. The agent contains potassium peroxomonosulfate (an oxidizing agent) as its main ingredient and sodium chloride as one of its compounding ingredients. Potassium peroxomonosulfate oxidizes sodium chloride to generate hypochlorous acid. The oxidation action of hypochlorous acid and potassium peroxomonosulfate oxidizes and decomposes the proteins that make up bacteria and viruses. The chloride ions generated after the hypochlorous acid reacts with organic matter become sodium chloride, which serves as a source of new hypochlorous acid, and this reaction repeats. The disinfectant is in granular form and is stored in a sealed packaging bag. When used, the granular agent is removed from the packaging bag and diluted with water. If the disinfectant is colored pink, the disinfectant solution will also be colored approximately the same pink as the agent.

[0007] However, when a colored agent is diluted with water, unevenness inevitably occurs, and when a pink-colored disinfectant is soaked into a white nonwoven fabric, color spots appear. As a result, it gives the impression of poor product quality, so the nonwoven fabric that forms the base material of disinfectant wipes is required to be colored the same color as the disinfectant so that it does not look strange when immersed in the disinfectant.

[0008] The nonwoven fabric that forms the nonwoven fabric roll in conventional disinfectant packages is the base material for disinfectant wipers, and contains cellulosic fibers to improve the disinfectant liquid retention capacity and hydrophobic synthetic fibers to improve wiping properties.Furthermore, to color it pink, a pattern in approximately the same color as the disinfectant liquid is printed on the surface using a pigment and an acrylic emulsion binder. [Prior art documents] [Non-patent literature]

[0009] [Non-Patent Document 1] Kyorin Pharmaceutical Co., Ltd. [Searched February 8, 2024], Internet<https: / / www.rubysta.jp / > Summary of the Invention [Problem to be solved by the invention]

[0010] However, in the above-mentioned disinfecting wipes, the disinfectant solution impregnated in the nonwoven fabric is separated from the nonwoven fabric due to the influence of the cellulosic fibers and binder, and is not efficiently distributed over the object to be wiped. In other words, there is a problem that the concentration of the disinfecting active ingredient in the disinfectant solution decreases in the nonwoven fabric, and the disinfecting active ingredient in the disinfectant solution is not efficiently released (the above requirement (1) is not met).

[0011] On the other hand, although the disinfecting effect can be improved by mixing a high concentration of disinfectant at the time of filling, the disinfectant concentration may exceed the safety standard or the product may not be able to be manufactured cheaply, resulting in an expensive product (not meeting the requirement of (4) above).

[0012] Here, if hydrophobic synthetic fibers were used instead of cellulosic fibers as the base material of disinfecting wipers to solve the above-mentioned problems, even if the decrease in the concentration of the disinfecting active ingredient could be suppressed, there would be problems in that printing costs would be high (requirement (4) above would not be met), and the hydrophilic properties required for dry wiping without being impregnated with disinfectant liquid, and the liquid retention properties that allow a single wiper to wipe a wider area and maintain a moist state that can fully exert disinfecting effects against viruses, bacteria, etc. would not be expected (requirement (2) above would not be met).

[0013] The present invention has been made in view of the above-mentioned problems of the prior art. One object of the present invention is to provide a disinfectant package that can easily produce disinfectant wipes that have excellent release performance of disinfecting components impregnated in the nonwoven fabric, high hydrophilicity and liquid retention properties, and can be manufactured inexpensively by immersing a nonwoven fabric roll, which is formed by winding a long nonwoven fabric colored to be substantially the same color as a disinfectant solution, in the disinfectant solution in a container.

[0014] Another object of the present invention is to provide a nonwoven fabric that is colored to be substantially the same color as a disinfectant solution, and that when the nonwoven fabric is immersed in the disinfectant solution to complete a disinfectant wiper, the disinfectant wiper has excellent release performance of the disinfectant component impregnated in the nonwoven fabric, has a high disinfectant solution retention capacity, and can be manufactured at low cost.

[0015] A disinfection package according to a first aspect of the present invention comprises a nonwoven fabric roll formed by winding a long nonwoven fabric colored to be substantially the same color as a disinfectant solution into a roll, a container for storing the nonwoven fabric roll, and a lid having an outlet for the nonwoven fabric and detachably attached to the container so as to seal the nonwoven fabric roll, wherein the nonwoven fabric can be used as a disinfectant wiper by immersing the nonwoven fabric roll in the container, and the nonwoven fabric of the nonwoven fabric roll is a hydrophilic nonwoven fabric having a hydrophilic property. The fabric is made by hydroentangling aqueous synthetic fibers and hydrophobic synthetic fibers having hydrophobic properties, and at least one of the hydrophilic synthetic fibers and the hydrophobic synthetic fibers is colored by mixing a pigment into the raw material. The fabric has the hydrophilic performance required for dry wiping applications in which the fabric is used without being impregnated with a disinfectant and the liquid retention performance required for wiping applications in which the disinfectant is spread over a wide area, and the weight ratio of the hydrophilic synthetic fibers to the hydrophobic synthetic fibers is adjusted so that the fabric has approximately the same color as the disinfectant.

[0016] Moreover, the disinfectant package according to the second aspect of the present invention is characterized in that the hydrophobic synthetic fiber is colored by mixing a pigment into the raw material.

[0017] Furthermore, a nonwoven fabric according to a third aspect of the present invention is a nonwoven fabric roll for constituting a disinfection package, the nonwoven fabric roll comprising a long nonwoven fabric colored to be substantially the same color as a disinfectant solution and wound into a roll shape, a container for storing the nonwoven fabric roll, and a lid having an outlet for the nonwoven fabric and detachably attached to the container so as to seal the nonwoven fabric roll, the nonwoven fabric being usable as a disinfectant wiper by immersing the nonwoven fabric roll in the container, the nonwoven fabric comprising a hydrophilic synthetic fiber having hydrophilicity, The hydrophilic synthetic fiber is formed by hydroentangling hydrophobic synthetic fibers that have been colored by mixing a pigment into the raw material, and at least one of the hydrophilic synthetic fiber and the hydrophobic synthetic fiber is colored by mixing a pigment into the raw material, and the hydrophilic synthetic fiber has the hydrophilic performance required for dry wiping applications in which the fiber is used without being impregnated with a disinfectant and the liquid retention performance required for wiping applications in which the disinfectant is spread over a wide area, and the weight ratio of the hydrophilic synthetic fiber to the hydrophobic synthetic fiber is adjusted so that the color is approximately the same as the color of the disinfectant.

[0018] Furthermore, the nonwoven fabric according to a fourth aspect of the present invention is characterized in that the hydrophobic synthetic fibers are colored by mixing a pigment into the raw material.

[0019] Furthermore, a disinfection package according to a fifth aspect of the present invention comprises a nonwoven fabric roll formed by winding a colored long nonwoven fabric into a roll, a container for storing the nonwoven fabric roll, and a lid having an outlet for the nonwoven fabric and removably attached to the container so as to seal the nonwoven fabric roll, wherein the nonwoven fabric can be used as a disinfectant wiper by immersing the nonwoven fabric roll in the container in the disinfectant solution, characterized in that the nonwoven fabric of the nonwoven fabric roll is made by hydroentangling synthetic fibers and is colored by mixing a pigment into the raw material.

[0021] As described above, the present invention provides a disinfecting wiper that has excellent disinfectant component release performance, high disinfectant solution retention, and high wiping performance for various disinfecting chemicals, and can be manufactured inexpensively. Furthermore, since the synthetic fibers themselves are colored by incorporating pigments into the raw materials, the color of the nonwoven fabric does not fade during use. Therefore, it is possible to prevent users from getting the impression that the disinfecting wiper is of low quality due to color fading of the nonwoven fabric during use.

[Figure 2] FIG. 10 is a diagram showing the relationship between wiping area and liquid release rate. DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, preferred embodiments of the present invention will be described based on preferred examples, but the present invention is not limited to these. (Disinfection package)

[0024] A disinfectant package according to one embodiment of the present invention comprises a nonwoven fabric roll formed by winding a long nonwoven fabric colored to be substantially the same color as the disinfectant solution, a container for storing the nonwoven fabric roll, and a lid having an outlet for the nonwoven fabric and removably attached to the container so as to seal the nonwoven fabric roll. The nonwoven fabric roll can be used as a disinfectant wiper by immersing the nonwoven fabric roll in the disinfectant solution within the container. In this invention, the term "package" refers to an item that is packaged or placed in a container, including the package and the container. Furthermore, "wiping" refers to wiping with a wet cloth, and also includes subsequent wiping with a dry cloth. (nonwoven fabric)

[0025] The nonwoven fabric of the nonwoven fabric roll is made by hydroentangling hydrophilic synthetic fibers with hydrophobic synthetic fibers that have been colored by mixing a pigment into the raw material, and the weight ratio of the hydrophilic synthetic fibers to the hydrophobic synthetic fibers is adjusted so that the nonwoven fabric has the hydrophilic properties required for dry wiping applications that are used without impregnating the disinfectant solution and is approximately the same color as the disinfectant solution. The nonwoven fabric of the nonwoven fabric roll is also perforated at predetermined length intervals so that it can be torn along the perforations to create nonwoven fabric pieces when in use. (disinfectant)

[0026] The disinfectant solution for soaking the nonwoven fabric roll is prepared by dissolving a chlorine-based agent in water. The agent, as in conventional methods, contains potassium peroxomonobisulfate (an oxidizing agent) as the main component and sodium chloride as one of the compounding components. The potassium peroxomonobisulfate oxidizes the sodium chloride to generate hypochlorous acid, and the oxidizing action of hypochlorous acid and potassium peroxomonobisulfate oxidizes and decomposes the constituent proteins of bacteria and viruses. The agent is colored pink and is stored in a sealed agent bag. When preparing the disinfectant solution, the agent bag is opened and removed, and the agent is placed in a container containing water to dissolve in water. The agent bag containing the agent may be stored outside the container, or it may be stored in the gap between the container and the nonwoven fabric roll, or in a hollow space formed in the center of the nonwoven fabric roll, within the container. (hydrophilic synthetic fiber)

[0027] The hydrophilic synthetic fibers are polyester fibers coated with a known highly durable hydrophilizing agent for nonwoven fabrics. In this embodiment, PET (polyethylene terephthalate) fibers are used as the polyester fibers. However, PTT (polytrimethylene terephthalate), PBT (polybutylene terephthalate), PLA (polylactic acid fiber), etc. may be used instead of PET. (hydrophobic synthetic fiber)

[0028] The hydrophobic fibers are colored a little darker than the color of the specified disinfectant by kneading a masterbatch into a clear synthetic resin that becomes polyester fibers. (Amount of hydrophilic fiber mixed)

[0029] The weight ratio of the hydrophilic synthetic fibers to the hydrophobic synthetic fibers in the disinfecting wiper is preferably in the range of 3:7 to 7:3. If the content of the hydrophobic synthetic fibers in the disinfecting wiper is less than 30% by weight, the color of the nonwoven fabric will be too light compared to the color of the disinfectant solution, causing the disinfecting wiper to appear mottled, giving the impression of a substandard product. Furthermore, the amount of hydrophilic synthetic fibers will be too high, making the nonwoven fabric expensive. If the content of the hydrophobic synthetic fibers in the disinfecting wiper exceeds 70% by weight, the color of the nonwoven fabric will be too dark compared to the color of the disinfectant solution, giving the impression of a substandard product, and reducing the liquid absorption performance of the nonwoven fabric. However, by optimizing the weight ratio of the hydrophilic synthetic fibers to the hydrophobic synthetic fibers in the disinfecting wiper, a disinfecting wiper can be obtained that is within a practical range in terms of the color compatibility of the nonwoven fabric with the colored disinfectant solution, the ability to retain the concentration of disinfecting active ingredients, and the liquid retention performance. Furthermore, since the content of the relatively expensive hydrophilic fibers is kept to 70% or less, the wiper can be manufactured inexpensively. More preferably, the blended amount of hydrophilic fibers in the disinfecting wiper is 50% by weight. This is because it provides an optimal disinfecting wiper that is well-balanced in terms of disinfectant release performance, wiping performance, liquid retention performance, and cost. Even if the weight ratio of hydrophilic fibers to hydrophobic synthetic fibers is set to 3:7 during the manufacturing process, some variation in the finished product may occur due to uneven texture and manufacturing precision. Experience has shown that a manufacturing variation of approximately ±10% can be considered acceptable. Therefore, if the hydrophilic fiber content of the finished product is 27-33% by weight, it can be assumed that the finished product has been manufactured with a weight ratio of hydrophilic fibers to hydrophobic synthetic fibers of 3:7. If the hydrophilic fiber content of the finished product is 63-77% by weight, it can be assumed that the finished product has been manufactured with a weight ratio of hydrophilic fibers to hydrophobic synthetic fibers of 7:3. (disinfecting wipes)

[0030] The disinfecting wiper is formed into a square shape by pulling out the nonwoven fabric from a roll of nonwoven fabric immersed in a disinfectant solution and cutting it along perforations. Alternatively, the nonwoven fabric roll can be pulled out from the roll of nonwoven fabric without immersing it in a disinfectant solution and cut along perforations to form a dry square piece of nonwoven fabric, which can be used as a wiper for dry wiping. (Nonwoven fabric manufacturing process)

[0031] In the manufacturing process of the nonwoven fabric for the disinfectant wiper of the disinfectant package according to this embodiment, hydrophilic fiber raw cotton, the surface of which has been coated with a known high-durability hydrophilizing agent for nonwoven fabrics, and hydrophobic fiber raw cotton, colored by kneading a master batch into a clear synthetic resin, are each purified, and the hydrophilic fiber raw cotton and hydrophobic fiber raw cotton are mixed to the required weight ratio, and a continuous web or sliver is produced from the mixed raw cotton, which is then subjected to a carding process to make it suitable for subsequent processes.

[0032] After the carding process, the fibers are uniformly sent out to form a web or sliver, which is then subjected to a high-pressure water jet based on the spunlace method, which causes the fibers to entangle with each other and form a sheet. In the next process, this is dried to form a nonwoven fabric that serves as the base material for disinfecting wipes. [Example]

[0033] The present invention will be described in more detail below with reference to examples. However, the scope of the present invention is not limited by these examples. Figure 1 shows two types of nonwoven fabrics that serve as the base material for disinfecting wipers, with Figure 1(A) being a photograph of a nonwoven fabric according to an example of the present invention and Figure 1(B) being a photograph of a nonwoven fabric that serves as the base material for a conventional wiper. (Performance in maintaining the concentration of disinfectant active ingredients)

[0034] In disinfectant packages, the nonwoven fabric's ability to retain the chemical solution can be adjusted not only by the weight ratio of hydrophilic to hydrophobic synthetic fibers, but also by the type and amount of hydrophilizing agent in the hydrophilic synthetic fibers, and the compatibility of the nonwoven fabric's color with the disinfectant solution color can be adjusted not only by the weight ratio of hydrophilic to hydrophobic synthetic fibers, but also by the color and amount of the masterbatch, etc. However, the type of fiber and substances attached to the fiber surface are thought to have a significant impact on the retention of the disinfectant solution concentration. Therefore, the following test was conducted to verify the retention of the disinfectant solution concentration in disinfectant wipes.

[0035] Three types of nonwoven fabrics, each with a different weight ratio of hydrophilic and hydrophobic synthetic fibers, were prepared as the nonwoven fabric rolls included in the disinfection package according to this embodiment, and these were immersed in the same disinfectant solution to produce disinfectant wipers Example 1, Example 2, and Example 3. A conventional nonwoven fabric formed by mixing cellulose fibers and polyester fibers was immersed in the same disinfectant solution as Examples 1 to 3 to produce disinfectant wiper Comparative Example 1. As the disinfectant solution, a 1% aqueous solution of the agent disclosed in Non-Patent Document 1 ("Rubysta" (registered trademark of Kyorin Pharmaceutical Group Factory Co., Ltd.): containing potassium hydrogen peroxomonosulfate (an oxidizing agent) and sodium chloride as the main ingredients) (hereinafter referred to as "1% Rubysta aqueous solution") was prepared.

[0036] The hydrophilic synthetic fibers in Examples 1 to 3 are polyethylene terephthalate fibers coated with a known highly durable hydrophilizing agent for nonwoven fabrics (hereinafter referred to as "hydrophilic PET"), and polyester fibers coated with a known highly durable hydrophilizing agent for nonwoven fabrics. The hydrophobic synthetic fibers are clear polyethylene terephthalate fibers colored a slightly darker pink than the specified disinfectant color by kneading a masterbatch into the fibers (hereinafter referred to as "dyed PET").

[0037] The nonwoven fabric in Example 1 was formed by hydroentangling a mixture of hydrophilic PET and dope-dyed PET at 70% by weight, the nonwoven fabric in Example 2 was formed by hydroentangling a mixture of hydrophilic PET and dope-dyed PET at 50% by weight, and the nonwoven fabric in Example 3 was formed by hydroentangling a mixture of hydrophilic PET and dope-dyed PET at 70% by weight. The nonwoven fabric in Comparative Example 1 was formed by hydroentangling a mixture of rayon fiber and polyethylene terephthalate fiber (hereinafter referred to as "fiber PET") at 70% by weight, and then printed on its surface with a pattern in approximately the same color as the disinfectant using a pigment and acrylic emulsion binder.

[0038] In Examples 1 to 3, the fiber diameter of the hydrophilic PET was 12.6 μm, the fiber diameter of the dope-dyed PET was 11.8 μm, and in Comparative Example 1, the fiber diameter of the rayon fiber was 12.0 μm, and the fiber diameter of the PET fiber was 11.8 μm. The basis weight of each nonwoven fabric in Examples 1 to 3 and Comparative Example 1 was 40 g / m 2 is.

[0039] The nonwoven fabrics according to Examples 1 to 3 and Comparative Example 1 were each immersed in a disinfectant solution to complete the disinfectant wipes, and the remaining rate of the active ingredient, which is an indicator of the disinfectant active ingredient's ability to retain its concentration, was required to be 70% or more 14 days after completion. Therefore, the disinfectant wipes were examined for their ability to retain the disinfectant active ingredient's concentration and their liquid absorption ability 14 days after completion. (Performance in maintaining the concentration of disinfectant active ingredients)

[0040] First, when the agent was dissolved in water to prepare a disinfectant solution, the concentration of the active ingredient in the disinfectant solution was determined as an initial value by iodometric titration, and the active ingredient concentration and active ingredient residual rate of the disinfectant solution 14 days later were determined.The disinfectant solutions collected from the disinfectant wipers of Examples 1 to 3 were used as samples, and the active ingredient concentration of the disinfectant solution 14 days after the date of collection of the sample was determined by iodometric titration, and the active ingredient concentration residual rate was calculated based on the active ingredient concentration.The results are shown in Table 1. [Table 1]

[0041] One disinfecting wiper was produced for each of Example 1 and Comparative Example 1, and three disinfecting wipers were produced for each of Example 2 and Example 3, with two samples prepared from each disinfecting wiper. The amount of active ingredient used in the iodometric titration method was the average value of the two samples, and the active ingredient remaining rate after 14 days was calculated based on this average value. For Examples 2 and 3, the active ingredient concentration after 14 days shown in Table 1 is the average value for the three disinfecting wipers for each Example. The minimum active ingredient remaining rate among the disinfecting wipers of Examples 1 to 3 was 70.59%. (Hydrophilic performance)

[0042] A test was conducted to verify the hydrophilicity required for dry wiping applications without impregnating the nonwoven fabric of this embodiment with a disinfectant. In this test, a nonwoven fabric formed using a normal polyester that had not been hydrophilized was prepared as Comparative Example 2 instead of the hydrophilic PET of Example 3. The water absorption of each of Example 3, Comparative Example 1, and Comparative Example 2 was determined based on JIS L 1912: Test method for medical nonwoven fabrics (6.12 Water absorption). The results are shown in Table 2. [Table 2] (liquid retention performance)

[0043] A test was conducted to verify the liquid retention performance required for wiping applications in which the disinfectant solution is spread over a wide area for the nonwoven fabric of this embodiment. In this test, the liquid release rate was measured for each of Example 3 and Comparative Example 1 using the liquid release rate measurement method described below.

[0044] The method for measuring the liquid release rate comprises a liquid absorption step, an initial weight measurement step, a wiping step, a weight remeasurement step, and a release amount calculation step.

[0045] In the liquid absorption process, multiple 140 mm x 259 mm nonwoven fabric samples, 5 g of water x the number of samples, and a zippered plastic bag are prepared, and the number of samples to be used for measurement and the prepared water are sealed in the zippered plastic bag.The samples are left to stand for 30 minutes to allow the water to spread throughout the samples, and 5 g of water is absorbed per sample.

[0046] In the initial weight measurement step, the weight of the sample that has absorbed water is measured and is taken as the weight when the wiping area is 0.

[0047] In the wiping step, the water-absorbed sample is attached to a jig, and the top surface (wiping surface) of the table is wiped with the sample.

[0048] To attach the sample to the jig, place the sample on the surface to be wiped, place the jig (iron plate) on top of the sample, fold the front side over to prevent it from slipping during wiping, and place the iron plate as a weight so that it sandwiches the folded part.

[0049] To wipe the surface with the sample, place a weight on the jig to adjust the weight, and slide the sample once along the long side of the table. At this time, the area of ​​the jig is 280 cm. 2 The load applied to the sample was 2 g / m 2 The sample moving speed is 15 m / min.

[0050] In the weight re-measurement step, the weight of the sample is measured immediately after the wiping step. The weight of the sample measured after the first wiping step is 0.25 m 2 This is the weight for one wipe (0.14m x 1.8m).

[0051] In the release amount calculation process, the wiping process and the weight re-measurement process are repeated a predetermined number of times, and each time the amount of water released for each wiping is calculated, and the liquid release rate is calculated based on the amount of water released for each wiping and the amount of water absorbed in the liquid absorption process (5 g).

[0052] Here, n is the number of wipings, weight n is the weight of the sample when wiping is performed n times, and weight n-1 is the weight of the sample when wiping is performed n-1 times. The amount of liquid released when wiping is performed n times is the difference between (weight n) and (weight n-1). The liquid release rate (%) when wiping is performed n times is calculated by dividing the difference between (weight n) and (weight n-1) by the amount of water absorbed in the liquid absorption step and multiplying the result by 100. The wiping area when wiping is performed n times is 0.25 m. 2 The liquid retention performance test results are shown in Table 3 and Figure 2. [Table 3] (Discussion of test results)

[0053] As shown in Table 1, all of the specimens according to Examples 1 to 3 exceeded the target value of 70% for the active ingredient residual rate. In contrast, the specimen according to Comparative Example 1 had an active ingredient residual rate of 56.15%. Therefore, it can be seen that Examples 1 to 3 are superior to Comparative Example 1, which is a conventional product, in terms of the ability to retain the concentration of disinfecting active ingredients.

[0054] Furthermore, as shown in Table 2, the water absorption capacity of Example 3 is about 10 times that of Comparative Example 2, which uses polyester that has not been hydrophilically treated, and is slightly smaller than that of Comparative Example 1, a conventional product, but since the difference is within the margin of error, it can be said that Example 3 has a water absorption capacity approximately equivalent to that of Comparative Example 1. Therefore, Example 3 has sufficient hydrophilic performance required for dry wiping applications that are used without impregnating with a disinfectant solution.

[0055] Furthermore, as shown in Table 3 and Figure 2, when the liquid release rate of Example 3 is compared with that of Comparative Example 1, both show roughly the same tendency to change even when the number of wiping cycles is increased, and the difference between them is small. Example 1 has a slightly higher final release amount than Comparative Example 1, and it is thought that stable wiping is possible because the difference in release amount is small even when the wiping area is increased. Therefore, Example 3 has sufficient liquid retention performance required for wiping applications in which disinfectant solution is spread over a wide area.

[0056] According to the present invention, if necessary, only the hydrophilic synthetic fibers may be colored by mixing a pigment into the raw material thereof, or both the hydrophobic synthetic fibers and the hydrophilic synthetic fibers may be colored by mixing a pigment into each of the raw materials thereof.
