Benefits of technology

[0087] When a nonwoven fabric is used in the flexible sheet in the present invention, mention is made of spun lace, spun bond, melt blown, needle punch and / or stitch bond in addition to wet nonwoven fabrics and dry nonwoven fabrics such as chemical bond, thermal bond (air-through) and air-laid, and particularly one or more members selected from wet nonwoven fabrics, chemical bond, thermal bond (air-through), melt blown and spun lace are effective in respect of the effect of the invention. Low-interweaved nonwoven fabrics composed of fibers having a fiber length of 20 mm or more, particularly 30 to 100 mm, especially 35 to 65 mm, are preferably used.
[0088] Such low-interweaved nonwoven fabrics include spun lace nonwoven fabrics, thermal bond nonwoven fabrics such as air-through, spun bond nonwoven fabrics, and three-dimensionally raised nonwoven fabrics. In this case, a low-interweaved nonwoven fabric composed of fibers having a fiber length of 20 mm or more does not require the fiber lengths of all constituent fibers to be 20 mm or more, and incorporation of fibers with a fiber length of less than 20 mm inevitably mixed and / or generated in a starting material of the nonwoven fabric and / or in the production process is allowed. Formation of a large number of embossed portions on the surface of the wiping material of the present invention by thermal embossing is preferable in respect of improvement in operativeness at the time of cleaning (reduction in frictional resistance).
[0089] The present invention also provides the following cleaning method for reducing allergen. That is, the cleaning method includes spraying or applying the allergen-reducing agent of the present invention onto the surface of an object before cleaning by vacuuming or sweeping cleaning and then wiping it off with a water-absorbing article before the allergen-reducing agent is dried. Cleaning by vacuuming or sweeping cleaning causes allergen to be scattered, and thus a more sufficient effect can be obtained by previous allergen reducing treatment than by allergen reducing treatment after cleaning. The cleaning method of the present invention unlike conventional wiping cleaning involves treating a rigid surface with the allergen-reducing agent of the present invention prior to the cleaning, whereby excellent removability of allergen can be achieved. For the water-absorbing article used in wiping, the description of the flexible sheet can be referred to. The method of the present invention also involves wiping a water-absorbing article impregnated with the allergen-reducing agent of the present invention. In connection with this, the present invention provides the allergen-reducing agent of the present invention provided with an indication to the effect that it is used in such specific cleaning method.
[0090] The allergen-reducing agent contained in a spray container is used in a method of directly spraying it onto a treatment object to make allergen harmless on the surface of the object. As used herein, the surface of the object refers to any surface to which allergen can adhere, and includes the floor surface of flooring, a cushion floor, a tatami mat etc. and the surface of furniture made of wood, leather, glass, metal and plastics and the surface of electrical appliances and coated surfaces thereof.
[0091] As the water-absorbing article, it is possible to use a liquid-absorbing article, for example a cloth such as a dustcloth etc., a nonwoven fabric, and a porous article such as sponge and paper. Particularly, a nonwoven fabric and sponge are preferable in respect of operativeness and the amount of retainable liquid, and the form is preferably a sheet shape or roller shape. Generally, when one absorbent is used repeatedly in wiping treatment, there is the case where allergen removed once by absorption into the absorbent adheres again to a rigid surface, and thus a sufficient allergen reducing effect may not be obtained. In the present invention, however, there is no such problem. This is because even if allergen adheres again to a treatment surface, the allergen dissolved once in the allergen-reducing agent of the present invention has been made harmless by the component (a). Accordingly, the method described above may use an absorbent impregnated with the allergen-reducing agent. As a matter of course, a means for preventing re-adhesion is preferably taken, and in this case, an absorbent containing cellulose fibers is preferably used, and specifically a fiber structure containing cellulose fibers described later can be used.
[0092] As described above, the allergen-reducing agent of the present invention is used in the allergen reducing method which includes spraying or applying it onto the surface of an object and then wiping it off with a water-absorbing article before the allergen-reducing agent is dried, and thus the present invention also provides the allergen-reducing agent of the present invention provided with an indication to the effect that it is used in the specific allergen reducing method.

example 1

[0143] Compounds A1 to M shown in Table 1 and Aculyn 22 were used to prepare sample solutions containing 0.01 wt % Compounds A1 to M and 15 wt % ethanol (special grade, SIGMA), the balance being water. These sample solutions were examined for the degree of residual activity of mite allergen R by the following QAS method. The results are shown in Table 1.

example 2

[0152] Space with a floor area of 7.4 m2 and a height of 2.3 m (capacity 17 m2, temperature 23° C.) was sealed, and a cotton futon actually used for 2 years in home was given with an impact for 10 seconds with a futon beater to generate dust in the space and stir up the dust. Then, 17 g of the allergen-reducing agent in Table 2 was sprayed into the space upward at a direction of 45° from a height of 1.7 meters over the floor by using a trigger-type spray (trigger attached to ALERUCLEAN Cleaning Spray for futon, manufactured by Kao Corporation).

[0153] Thirty minutes after spraying, a high-volume air sampler (HV-500F, Shibata Scientific Technology Ltd.) equipped with a glass fiber filter (GB-100R-110A, Shibata Scientific Technology Ltd.) was operated under the condition of 500 L / min. for 60 minutes on the floor, to capture dust on the filter. The glass fiber filter on which the dust had been captured was squeezed in 1 cc or less solution containing PBS (phosphate buffer solution, pH ...

[0156] Space with a floor area of 7.4 m2 and a height of 2.3 m (capacity 17 m2, temperature 23° C.) was sealed, and a cotton futon actually used for 2 years in home was given with an impact for 10 seconds with a futon beater to generate dust in the space and stir up the dust.

[0157] After 3 hours, the floor surface was cleaned at 20 seconds / m2 with a vacuum-cleaner (CV-CD4, suction power of 530 W, manufactured by Hitachi, Ltd.). Immediately thereafter, a sheet structure A wherein a nonwoven fabric obtained by a method of preparing a nonwoven fabric as shown below was impregnated at an impregnation degree of 250% (ratio by weight) with the allergen-reducing agent in Table 2 was fitted in Quickle Wiper (Kao Corporation) and used to wipe the floor surface.

[0158] After wiping, the floor surface was left for 3 hours and then wiped the whole floor surface with a wiping sheet B having a commercial cleaning sheet (Floor Quickle Dry Type, Kao Corporation) impregnated at an impregnation degr...

Abstract

The invention provides a means capable of effectively inactivating and removing allergen or a precursor thereof. The invention relates to an allergen-reducing agent containing water and a water-soluble polymer compound having units having hydroxy or carboxy groups wherein at least a part of hydrogen atoms of the hydroxy or carboxy groups are substituted by specific groups containing a polyether group.

Description

TECHNICAL FIELD [0001] The present invention relates to a method of easily removing allergen or its precursor floating in housing space and an allergen-reducing agent used for the method. FIELD OF THE INVENTION [0002] Allergic diseases attributable to house dust tend to increase in recent years and become a social problem. Typical examples of house dust causing allergy can include pollen, mold spores, and dead bodies and excrements of mites, but these are very fine substances of several to tens μm and can thus be stirred up even by simple activity such as human walking to contaminate housing space. The house dust stirred up to float in the space cannot be removed by general cleaning action, so there is an ardent desire for a method of effectively removing house dust floating in space. [0003] JP-A 2000-264837 discloses an allergen removing agent as a cationic surfactant-containing composition to be sprayed into space. JP-A 2002-128659 discloses a house dust-treating agent sprayed int...
