Description

TECHNICAL FIELD The present invention relates to a wiping cloth capable of imparting an antibacterial effect to a surface to be cleaned, and a mop provided with the wiping cloth.

In the case of wiping and cleaning the surface to be cleaned, such as the floor, with a mop cloth, it is desired to not only remove dirt and dust on the surface to be cleaned, but also to impart an antibacterial effect to the surface to be cleaned. there is

However, with the conventional wiping cloth, the antibacterial effect imparted to the surface to be cleaned was lost in a short period of time. Therefore, the antibacterial effect of the surface to be cleaned cannot be maintained for a long period of time.

The present invention provides a wiping cloth that can impart a long-lasting antibacterial effect to the surface to be cleaned by improving the disinfecting liquid impregnated in the wiping cloth. To provide a mop with a wiping cloth.

A first aspect of the present invention is a wiping cloth impregnated with a disinfectant solution, wherein the disinfectant solution contains 0.15 to 25% by weight of a silver-containing antibacterial component and 3.0 to 10.0% by weight of a silver-containing antibacterial component. It is characterized by containing a binder component, a nonionic surfactant, and a sterilizing component.

A second aspect of the present invention is a mop comprising the wiping cloth of the first aspect and a handle holding the wiping cloth.

According to the wiping cloth of the first aspect and the mop of the second aspect, when used for wiping a surface to be cleaned, a long-lasting antibacterial effect can be imparted to the surface to be cleaned.

1 is a perspective partial view of the mop of the present invention; FIG. 2 is a side view of the mop of FIG. 1; FIG. This mop 10 consists of a wiping cloth 1 and a handle 2. - 特許庁The handle 2 is composed of a holding portion 21 and a handle 22 . The holding part 21 holds the wiping cloth 1 by sandwiching both edges 11 of the wiping cloth 1 between the two bodies 211 and 212 when the upper body 212 is placed on the lower body 211 .

FIG. 3 is a plan view of the wiping cloth 1. FIG. FIG. 4 is a sectional view along IV-IV in FIG. The wiping cloth 1 is constructed by tufting piles 13 on both sides of a base cloth 12 which is rectangular in plan view. However, the pile 13 is not tufted on both edges 11 of the base fabric 12 . The base fabric 12 is, for example, nylon fabric. The pile 13 is, for example, twisted yarn of polyethylene yarn and nylon yarn, for example, cut pile.

The pile 13 of the wiping cloth 1 is impregnated with a predetermined sterilizing liquid. This sterilization liquid contains 0.15 to 25% by weight of a silver-containing antibacterial component, 3.0 to 10.0% by weight of a binder component, a nonionic surfactant, and a sterilization component. there is In this case, "sterilization" means removing bacteria, and "antibacterial" means suppressing the growth of bacteria.

As the silver-containing antibacterial component, it is preferable to use the registered trademark "Ag Alpha" (manufactured by J-Chemical Co., Ltd.). As the binder component, it is preferable to use the trade name "Nichigo Polyester" (manufactured by Mitsubishi Chemical Corporation), but the trade name "Plus Coat" (manufactured by GOO Chemical Industry Co., Ltd.) may also be used. Ethanol or phenyl glycol is preferably used as the sterilizing component, but isopropylmethylphenol and alkyl glycoside may also be used.

Note that the wiping cloth 1 is stored in a sealed bag together with a disinfecting liquid until just before it is held by the holding portion 21 of the handle 2 . As a result, the wiping cloth 1 is impregnated with the disinfecting liquid. The wiping cloth 1 is taken out from the sealed bag and held by the holding portion 21 .

[Examples 1 to 3]
As shown in Table 1, a disinfecting liquid to be impregnated in the wipe cloth 1 of Examples 1 to 3 was prepared.

After the wiping cloth 1 was impregnated with the disinfecting liquid of Example 1, the wiping cloth 1 was held by the holding portion 21 . Then, the mop 10 was used for cleaning. The sterilization liquids of Examples 2 and 3 were also tested in the same manner.

(Evaluation method)
The mop 10 of Example 1 was used to wipe the surface of a 5 cm square plastic plate. Then, the antibacterial properties of the surface of the plastic plate were evaluated by "Method A" and "Method B".

"Method A"
The plastic plate was left for 4 weeks in a room adjusted to a temperature of 20°C and a humidity of 65%. Then, an antibacterial test was carried out on the surface of the plastic plate.

"Method B"
The surface of the plastic plate was trampled with the number of trampling times corresponding to 4 weeks. Then, an antibacterial test was carried out on the surface of the plastic plate. Here, the number of times of trampling corresponding to four weeks is "2100 times" obtained by the following formula.
15 times/day x 28 days x 2.5 people (average per household) x 2 (margin rate) = 2100 times

In addition, the antibacterial test was implemented based on JISZ2801:2012 "film adhesion method."

The mops 10 of Examples 2 and 3 were similarly evaluated.

(Evaluation results)
For all the mops 10 of Examples 1 to 3, the activity value indicating antibacterial activity was 2.0 or more in both "Method A" and "Method B". This indicates that it still has high antibacterial properties even after 4 weeks. That is, according to the mop 10 using the wiping cloth 1 impregnated with the disinfecting liquid of Examples 1 to 3, a long-lasting antibacterial effect could be imparted to the surface to be cleaned.

Furthermore, the following events were observed.

(1) Silver-containing antibacterial component - When the amount was less than 0.15% by weight, antibacterial properties were not exhibited.
・When the amount exceeds 25% by weight, the stability is poor because of precipitation at low temperatures.

(2) Regarding the binder component ・When the content was less than 3 wt%, the antibacterial film formed on the floor by cleaning was peeled off by walking.
・When it exceeded 15 wt%, the cleaned floor surface became white.

(3) Nonionic surfactants - When anionic surfactants were used instead, yellow discoloration or black precipitation occurred.
- When a cationic surfactant was used instead, slight discoloration or turbidity occurred.

(4) When phenyl glycol is used as a sterilizing component: When it exceeds 1.0% by weight, it causes eye irritation.
When phenylglycol was not used, the activity value indicating antibacterial activity was less than 2.0.

(5) When ethanol is used as a sterilizing component: If the content exceeds 25% by weight, it irritates the eyes.
・When the content exceeds 50% by weight, silver precipitates and becomes cloudy.
・When the content was less than 15% by weight, the activity value indicating the antibacterial activity was less than 2.0.

(6) Antifoaming agent - When the content was less than 0.001 wt%, the antifoaming effect could not be exhibited.
- When the content exceeds 0.01 wt%, the antifoaming agent does not dissolve.

A mop equipped with the wiping cloth of the present invention can impart a long-lasting antibacterial effect to a surface to be cleaned, and therefore has great industrial utility value.
