DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunshade curtain and a sunshade sheet, and more particularly to an improvement thereof, and more particularly to a sunshade curtain and a sunshade sheet having a function of removing a bad smell in a room and a method of manufacturing the sunshade sheet.

[0002]

2. Description of the Related Art It is known that, in newly built houses, substances harmful to the human body are generated from new building materials and paints used for painting. Such harmful substances include formaldehyde, toluene, xylene, wood preservatives, plasticizers, termiticides, etc., which are mixed with indoor air in gaseous form, enter the lungs of persons breathing indoors, and enter the human body. It is absorbed into and has an adverse effect. In order to remove such harmful substances, a method of repeatedly ventilating indoor air has been adopted, but in this method, it took a long time, for example, several months to completely remove harmful substances. .

On the other hand, in a newly built house, during the period from the completion of the house to the time when the house is sold and the occupants enter the house, it is necessary to prevent the interior from being tanned or the temperature rising due to sunlight. Often, paper awning curtains are temporarily attached to curtain rails. However, this paper curtain is intended for awning and does not have a function of adsorbing or removing indoor harmful substances. It is known that, for example, activated carbon particles are appropriately adhered to a conventional cloth curtain to adsorb and remove the indoor odor. For example, Japanese Utility Model Laid-Open No. 59-118
No. 486 and Japanese Patent Application Laid-Open No. 5-69516 disclose a method in which a deodorizing member formed as a resin or rubber layer is laminated on a curtain material and integrated. Further, Japanese Patent Application Laid-Open No. 63-110289 discloses a sheet-shaped deodorizing member which is held inside a double bag constituting a curtain. Also,
Japanese Unexamined Utility Model Publication No. Sho 62-56036 discloses that activated carbon fibers respectively housed in a plurality of containers are detachable from a curtain.

[0004]

Problems to be Solved by the Invention
No. 8,486, JP-A-5-69516, JP-A-63-110289, and JP-A-62-56036 use a deodorizing (deodorizing) member mainly composed of activated carbon. It is used to physically adsorb and remove odor-causing substances, so if there are many odor-causing substances or harmful substances to be removed, not only these substances in the room cannot be completely absorbed. When the adsorption becomes saturated, there is a disadvantage that the malodorous substance and the harmful substance once adsorbed are released into the room again. In addition, these curtains provide a deodorizing function to ordinary cloth curtains, and such ordinary curtains are completely different in cost as compared with the temporary sunshade curtains for the above-mentioned new house, and the former is used as the latter. That is not practical.

Accordingly, the present invention provides a sunshade curtain and a sunshade sheet capable of removing harmful substances peculiar to a new house at the same cost as conventional sunshade curtains temporarily used for a new house. Aim. Another object of the present invention is to provide a method for manufacturing such a awning sheet.

[0006]

In order to achieve the above object, in the present invention, a curtain material made of non-woven fabric or paper containing pulp as a main component is impregnated with a liquid graft deodorizing agent and a harmful substance removing agent. The function of deodorizing and removing harmful substances is added to the function of awning.

That is, according to the present invention, a sheet made of nonwoven fabric or paper containing pulp as a main component, a graft deodorant and a harmful substance remover impregnated in the sheet, and a plurality of sheets attached to an end of the sheet And a suspending means for the sunshade.

Further, according to the present invention, there is provided a awning sheet having a sheet made of nonwoven fabric or paper containing pulp as a main component, and a graft deodorant and harmful substance remover impregnated in the sheet.

According to the present invention, the step of unwinding the sheet from a roll of a sheet made of nonwoven fabric or paper containing pulp as a main component, and removing the liquid graft deodorant and harmful substances from the unwound sheet Impregnating an agent, and then drying the sheet;
Winding the dried sheet and forming a new roll.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an elevation view showing the structure of the sunshade curtain of the present invention. This curtain is not a normal curtain, but is a shade that is temporarily used from the time a new house is constructed until it is sold and a resident enters. Such a temporary sunshade curtain for new homes, since it bid conventionally low (e.g. 1 m ² per 100 to 200 yen) is required, and little sheet of thick paper is used. Also in the present invention, a nonwoven fabric or a paper sheet containing pulp as a main component is used. However, in the present invention, the conventional curtain for awning for temporary use is not used as it is, but a curtain which is impregnated with a predetermined deodorant and harmful substance remover and dried is used.

FIG. 2 is a partial sectional view of FIG. As shown in FIGS. 1 and 2, the curtain fabric 10 is cut into a size corresponding to the size of a window of a house, and has a folded portion 12 at an upper end. A plurality of synthetic resin hirukan 14 are attached to the folded portion 12 so as to penetrate the folded portion 12. This synthetic resin Hirkan 14
A part of which constitutes a loop pin, a loop pin (wire) for attaching a tag made of synthetic resin for attaching a tag such as a price tag to clothing, etc., and engaging the ends thereof with each other. It is attached at predetermined intervals using an attachment gun. The hirukan 14 has a function of suspending the curtain fabric 10 by engaging with a runner 18 movably attached to a curtain rail 16 in the room. The Hirkan 14 has a ring portion 14A penetrating the folded portion 12 and a runner engaging portion 14B located above the ring portion 14A.

FIG. 3 is a schematic view showing an apparatus and a process for producing a roll of a curtain material impregnated with a deodorant and a harmful substance removing agent as a base of the curtain material 10. As shown in FIG. The curtain fabric 20 unwound from the curtain fabric roll 20A before impregnation with the deodorant and harmful substance remover is applied to the roller 22.
28, the sheet is conveyed as indicated by an arrow M1 in the figure, and is finally wound up to form a roll 20B. Roll 2
0B is rotated by a drive mechanism (not shown),
A part of 28 is also rotated by a drive mechanism not shown. The container 46 holds a liquid deodorant and harmful substance remover, and when the valve 48 is opened, the deodorant and harmful substance remover 5 is opened.
0 is poured into the lower sponge member 42. Below the sponge member 42, another sponge member 40 is arranged so as to sandwich the curtain fabric 20, and these two sponge members 40 and 42 are opposed to each other at a predetermined pressure by a mechanism not shown.

The deodorant and harmful substance remover 50 dropped from the container 46 is contained in these sponge members 40 and 42, and when the curtain 20 is transported between them.
The curtain material 20 is impregnated with the deodorant and harmful substance removing agent 50. The curtain material 20 is conveyed in a zigzag manner by the plurality of rollers 30 to 38 in order to dry the curtain material 20 which is wet by the hot air 54 from the heater 52. That is, the transport speed and the winding speed are controlled so that the roll 20B is wound up at the timing when the drying is completed.

As the deodorant and harmful substance remover 50, a graft deodorant and harmful substance remover can be used.
The graft deodorizing agent and harmful substance removing agent are obtained by introducing a functional group into a graft chain using a substrate as a strength material, and a cation exchange group or a sulfonic acid group and a carboxyl group can be used as the functional group. A deodorant using a cation exchange group is disclosed in Japanese Patent Publication No. 7-79593. Specifically, a molded article composed of a pulp and / or polyolefin base material has a cation exchange group. Things. In order to produce such a cationic deodorant, a reactive monomer is graft-polymerized to a molded article. Also,
Deodorizers using sulfonic acid groups and carboxyl groups are described in "Environmental Technology", May 1993, Vol.22 No.5, pp22-25, "Performance evaluation of pulp ball-based deodorizers""
Wherein a sulfonic acid group and a carboxyl group are introduced into a cellulosic pulp ball by applying a gamma ray simultaneous irradiation graft polymerization method.

[0015] These graft deodorants and harmful substance removers are chemically reacted with odor-causing substances and harmful substances,
They deodorize and detoxify these substances, and the principle of deodorization is different from that of activated carbon powder or granular activated carbon which physically adsorbs the substance causing the offensive odor. Therefore, the graft deodorant and harmful substance remover does not react any more after the chemical reaction with the predetermined amount of malodorous substance, but when adsorbing a certain amount of the substance causing malodor such as the one using activated carbon However, it does not release the causative substance adsorbed by saturation. The amount of time required to cause a chemical reaction with a certain amount of the odor-causing substance is not constant because it depends on the quality and quantity of the odor-causing substance. In the case of ordinary houses, the chemical reaction effect lasts for about 3 to 6 months, but harmful formaldehyde, toluene, xylene, wood preservatives, plasticizers, termite repellents, etc. Almost completely removable.

[0016] In addition to these harmful substances, in order to remove the smell of tobacco and other unpleasant odors, the curtain fabric 10 impregnated with the above-mentioned deodorant and harmful substance remover must be used.
In addition, an adsorption type deodorant containing activated carbon as a main component can be used in combination. As shown in FIG. 4, the adsorption type deodorant containing activated carbon as a main component can be configured to be held by a strip-shaped member 56 having a small bag portion 58 and suspended from the curtain fabric 10. . FIG. 5 is a sectional view of FIG. As shown in the figure, the strip-shaped member 56 is suspended from above the curtain fabric 10 by the magic tapes 60A and 60B. Therefore, the strip-shaped member 56 is detachable from the curtain fabric 10. However, if it is not necessary to make it detachable, it can be attached with an adhesive or glue, or sewn or stapled.

When activated carbon is used, different types of deodorants can be selected according to various types of odors. In this case, examples of the deodorant for different types of odors include GG (for general gas adsorption), GS (for solvent recovery), GC (for catalyst carrier), and KG (for catalyst carrier) in the lineup of granular activated carbon manufactured by Kuraray Chemical Co., Ltd. Solvent repair),
GM (for gas separation) or the like can be appropriately selected.
Further, when there are two or more types of bad odors, different types of deodorants can be used for each strip-shaped member 56.

In the embodiment shown in FIGS. 4 and 5, a second deodorant containing activated carbon as a main component is further added to the curtain material 10 which has been impregnated with a liquid graft deodorant and harmful substance remover and dried. Although described as being attached, instead of the second deodorant, or in addition to the second deodorant, a fragrance, a bactericide, an insect repellent, or another purpose is used, or a combination thereof is used. be able to.

[0019]

As described above, according to the present invention, a curtain made of non-woven fabric or paper containing pulp as a main component is impregnated with a liquid graft deodorizing agent and a harmful substance removing agent to provide an original sunscreen. Since the functions of deodorization and harmful substance removal are added to the function, harmful substances peculiar to the new house can be removed at the same cost as a conventional shade curtain temporarily used for a new house. Also, by using activated carbon in combination, a plurality of different types of odors can also be effectively removed.
