[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning material, and more particularly to, for example, an automobile body before painting, furniture such as a table, a desk, a closet, a cabinet, a chair, a plastic molded product, or a window. The present invention relates to a cleaning material suitable for cleaning a place where static electricity is easily generated due to friction with a cloth-like cleaning material in cleaning a door, a floor, and the like.

[0002]

2. Description of the Related Art For example, when painting an automobile, if dust in the atmosphere adheres to the part to be painted, the finish of the painting is poor. Therefore, it is necessary to clean the part to be painted before painting. is there. When a normal cleaning sheet made of a woven or non-woven fabric is used as this cleaning means, although the part to be coated can be temporarily cleaned, static electricity is generated due to friction between the cleaning sheet and the part to be coated, and dust in the atmosphere is rather generated. Easily adhered and was not suitable for practical use.
For this reason, cleaning was generally performed using both an ion neutralizing device and an adhesive cloth having a surface to which an adhesive or the like was applied, but this cleaning means removes electricity from the ion neutralizing device and then cleans the surface. Since the cleaning is carried out with a sticky cloth, the operation is complicated, and the ion neutralizer is expensive.

On the other hand, when cleaning furniture, plastic molded products, windows, doors, floors, and the like with a cleaning sheet made of ordinary woven or non-woven fabric, the cleaning sheet can be temporarily removed, but the cleaning sheet is not covered with the cleaning sheet. There is a problem that static electricity is generated due to friction with the object to be cleaned, and dust and the like easily adhere to the object to be cleaned. Therefore, a cleaning sheet using conductive fibers mixed with carbon black or metal powder or a metal-plated conductive fiber is known, but the former has a low fiber strength and is not durable, and the latter has a low durability. Has a problem that the object to be cleaned is damaged.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The cleaning material of the present invention is composed of a fiber sheet and contains conductive fibers coated with an electron conjugated polymer. For example , multiple bimetallic composite fibers or chrysanthemum composites composed of two or more resin components
Has an irregular cross-sectional shape derived from the fiber by the action of fluid flow
The use of fine fibers.

[0013] Such a conjugate fiber is a conjugate fiber (hereinafter referred to as "fine fiber") which can be made into a fine fiber having a fiber diameter of 9 µm or less by physical treatment , and a fine fiber derived therefrom. The cleaning material containing is excellent in static elimination property by corona discharge, cleaning property of the object to be cleaned, holding property of cleaned dust, etc., and is not only less likely to damage the object to be cleaned,
Since it is also excellent in strength, fine fiberized fibers can be suitably used. As the fine fibers of the fiber, as shown in FIG. 1, multiple bimetal type composite fibers having a cross section obtained by stacking in layers alternately with one component (A) and another component (B), or FIG.
2, as shown in FIG. 3, can be exemplified chrysanthemum-type composite fibers having a cross section in which one component (A) was divided by the other component extending fiber surface from the center of the fiber (B), these multiplex The fine fiber derived from the bimetallic conjugate fiber or the chrysanthemum flower conjugate fiber has an irregular cross-sectional shape such as a substantially trapezoidal shape or a fan shape, and is more excellent in cleaning properties and static elimination properties, and thus can be suitably used.

In order to make such a fine fiber into fine fibers , mechanical stress is applied by a fluid flow such as water to form each of the fine fibers as shown in FIGS. component (a), which need use the method according to the physical treatment of fine fibers by being split off from the boundary surface (B).

The resin component constituting the fine fiberized fiber may be composed of two or more components. Examples of the combination of the two components include, for example, a polyamide resin and a polyester resin, and a polyamide resin and a polyolefin. Resin, polyester resin and polyolefin resin, polyester resin and polyacrylonitrile resin, polyamide resin and polyacrylonitrile resin,
Polyolefin resins and polyacrylonitrile resins are exemplified.

The fine fiber derived from such a fine fiber is 5% by weight in the fiber sheet constituting the cleaning material.
It is preferable that the content be more than 50% by weight, more preferably more than 50% by weight, most preferably more than 90% by weight.

The thickness of the fibers constituting the fiber sheet used in the present invention must have an average fiber diameter of 10 μm or less, and if the average fiber diameter is larger than 10 μm,
Sufficient static elimination performance and wiping performance cannot be exhibited. When the average fiber diameter is in the range of 10 to 0.1 μm, the static elimination performance and the wiping performance are good, and the mechanical strength and the durability are not significantly reduced, which is preferable. Here, the fiber diameter, since a fiber having a deformed cross, refers to fiber diameter when converted to fibers of circular cross-section having the same cross-sectional area of the fiber.

The length of the fiber constituting the fiber sheet is usually about 1 to 160 mm, and the average fiber length is particularly preferably in the range of 20 to 110 mm. It is preferable that there is no drawback that the fibers are easily dropped due to being too short, and that the number of ends of the fibers constituting the fiber sheet is too small and the static elimination performance is not deteriorated.

The average fiber diameter and average fiber length refer to the average value of 100 randomly selected fibers.

As the fiber constituting the fiber sheet, it is preferable to use a drawn fiber from the viewpoint of durability, and a drawing ratio of about 1.5 to 5 times is preferably used.

The above-mentioned fibers are coated with an electronic conjugated polymer to form conductive fibers. However, if the fiber sheet is formed after coating in the fiber state, the electronic conjugated polymer is formed at the time of forming the fiber sheet. Because it may be damaged,
More preferably, the conductive sheet is formed by coating with an electron conjugated polymer after forming the fiber sheet. in this case,
There may be conductive fibers that are not completely coated with the electron conjugated polymer.

The adhesion rate of the electron conjugated polymer to the fiber sheet needs to be 0.05 to 3% by weight, and when the adhesion rate is less than 0.05% by weight, the static elimination performance of the obtained cleaning material. Is not preferred. On the other hand, if the adhesion ratio is more than 3% by weight, the flexibility of the obtained cleaning material is deteriorated, the workability in cleaning is reduced, and the electronic conjugated polymer peels off due to friction with the object to be cleaned. It is not preferable because it is easy to perform

Here, the adhesion rate X (% by weight) of the electron conjugated polymer to the fiber sheet is as follows:

[0024]

## EQU3 ## The adhesion rate X (% by weight) = [(weight of electron conjugated polymer) / (weight of electron conjugated polymer + weight of fiber sheet)] × 100.

Hereinafter, the case where the cleaning material of the present invention is formed by coating with an electron conjugated polymer after forming the fiber sheet will be described.

[0026] As the fiber sheet constituting the cleaning material of the present invention is a fluid flow entangled nonwoven fabric mentioned above, this
The non-woven fabric has an orientation direction of the fibers in the thickness direction, thereby increasing the number of fiber ends that can participate in corona discharge, facilitating static elimination by corona discharge, and has a three-dimensional void. Since dust and the like wiped off from the space can be held in this gap, it can be suitably used. The nonwoven fabric in which the orientation direction of the fibers is the thickness direction is, for example, a fiber web obtained by a direct method such as a dry method such as a card method or an air lay method, a wet method, a spunbond method or a melt blow method, and a fluid such as water. It can be obtained by entanglement with mechanical external force due to flow. Entangling with a fluid flow is more preferable because a more uniform nonwoven fabric having excellent strength can be obtained. When the fiber web is formed by the card method, if the orientation direction of the fibers includes a cross fiber web crossed by a cross layer or the like with respect to the length direction of the fiber web, the strength in the width direction is increased. And has excellent morphological stability,
As we can provide cleaning materials with excellent workability,
This is a more preferred orientation direction.

When a mechanical external force by a fluid flow is applied to a fiber web containing multi-bimetal type fibers or fine fiber fibers of chrysanthemum flower type fibers, the fine fibers are simultaneously entangled with the fine fibers. Therefore, there is no need to separately provide a fine fiber forming step, and this is a reasonable method for forming a nonwoven fabric. In addition, since it has a dense structure due to the entanglement of fine fibers, there is also a feature that it is more excellent in holding dust and the like.

Further, in order to improve the strength and abrasion resistance of the nonwoven fabric, a method of fixing with a binder such as an emulsion type, a solvent type, a powder type or the like, or a method of fusing the intersections of the fibers constituting the nonwoven type are adopted. Is preferable, but it is preferable to fix partially so as not to lower the static elimination property and the wiping property. In the case of this partial fixing, in order to improve the strength and abrasion resistance by fixing, and to prevent a decrease in static elimination property and wiping property, a fixing area of 0.01 to ⁵ mm ² per piece and a total fixing area Is preferably 5 to 50% of the area of the entire nonwoven fabric (the area when the surface of the nonwoven fabric is considered to be smooth). Among these, the method of partially fusing nonwoven fabric constituent fibers by embossing rolls or ultrasonic waves does not cause falling off of the binder or the like during use of the cleaning material, as in the case of fixing with a binder, resulting in improved cleaning properties. It is a more suitable method because it is excellent.

In order to further reduce the static elimination property, a two- or three-layer laminated fiber web having a fiber web containing heat-fusible fibers on one side or an intermediate layer may be heat-treated.

When a non-woven fabric is formed by entanglement of the fibers by applying a fluid flow, for example, a water flow, to the fiber web, a coarse mesh net of 50 mesh or more made of metal or plastic or the like is used. When a perforated plate is used as a support, the water flow is reflected at the portion where the net or the perforated plate is present, and the reflected water flow causes the fibers at the portion where the net or the perforated plate is present to be entangled with each other at the same time. Or an opening corresponding to a portion where a perforated plate is present (a hole communicating with the fiber sheet in a substantially thickness direction). This is hereinafter abbreviated as a nonwoven fabric having an opening. The nonwoven fabric having the openings has a structure of the nonwoven fabric in which the entangled fiber bundles substantially intersect with each other and at the intersection of the respective fiber bundles. The nonwoven fabric having the apertures has an advantage that dust and the like can be retained in the sheet from the side walls of the apertures, and therefore, the nonwoven fabric has more excellent dust retention. In the case of producing a nonwoven fabric having such openings with a water flow or the like, the conditions other than the support are not particularly limited. For example, the diameter of a nozzle for jetting a water flow is 0.05 to 0.3 mm, 0.2 pitch
It can be obtained by injecting a water flow at least once on one or both sides of the fiber web from a nozzle plate in which the nozzles are arranged in one row or nozzles are regularly or irregularly arranged in two or more rows. The jet pressure of the water jet injected from the nozzle may be about 10 to 300 kg / cm ² .

As described above, since all of the fiber sheets used in the present invention are porous, substantially the entire fiber sheet can be coated with the electron conjugated polymer. Since the electronic conjugated polymer has good adhesion to the fiber sheet and thus has excellent durability and flexibility, it can be wiped and discharged without damaging the object to be cleaned.

[0032] By employing the processing method of the above such textiles sheets, 10% modulus strength of the cleaning material finally obtained present invention, the vertical direction, with transverse directions 0.5 Kg / 5 cm width or more Is preferable because the form stability is good and the workability when using the cleaning material is good. From this point of view, the orientation direction of the fiber is a nonwoven fabric manufactured using a web in which a fiber web unidirectional to the length direction of the fiber web and a cross fiber web crossed by a cross layer or the like are laminated. The nonwoven fabric having the opening is one of particularly preferable ones.

In the present invention, the surface resistance of the cleaning material obtained by coating the electron conjugated polymer is about 1 ×.
It is preferably at most 10 ⁵ Ω / □. Surface resistance is 1 ×
If it exceeds 10 ⁵ Ω / □, the static elimination performance will decrease.
More preferably, it is 1 × 10 ⁴ Ω / □ or less.

As a method for coating with the electron conjugated polymer, for example, a polymerization catalyst such as iron (III) chloride [FeC
After a solution containing an oxidizing agent such as l ₃ ] or copper (II) chloride [CuCl ₂ ] was contained in the fiber sheet, it was brought into contact with the raw material monomer to be polymerized, or the raw material monomer was first contained in the fiber sheet. Later, there is a method of contacting with a solution containing an oxidizing agent such as iron (III) chloride or copper (II) chloride as a polymerization catalyst to carry out polymerization.

When the monomer is in a liquid state, the fiber sheet may be impregnated, coated, or sprayed with the monomer. When the monomer is in a gaseous state, the fiber sheet is placed in a container filled with the monomer. What is necessary is just to place a sheet.

Further, the polymerization catalyst can be impregnated, coated or sprayed to be contained in the fiber sheet or brought into contact with the fiber sheet.

The monomers capable of forming the electron conjugated polymer include, for example, acetylene, benzene, aniline, phenylacetylene, pyrrole, furan, thiophene, indole and derivatives of these monomers. Among these, pyrrole is excellent in conductivity and polymerizability, and excellent in static elimination and durability, and thus can be suitably used.

What is important here is the adhesion rate X (% by weight) of the electron conjugated polymer to the fiber sheet and the surface resistance Y (Ω) of the fiber sheet containing the conductive fiber coated with the electron conjugated polymer. / □) is the following formula (Equation 4)

[0039]

## EQU4 ## It is necessary to satisfy the relationship expressed by logY ≦ −0.8X + 5.

The expression (Equation 4) means that, as described above, if the amount of the electron conjugated polymer adhered is too large, the flexibility of the obtained cleaning material deteriorates, and the cleaning operation is performed. However, the electron conjugated polymer is easily peeled off due to friction with the object to be cleaned, which is not preferable. Therefore, it is preferable to reduce the amount of adhesion so as to fall within the above-described range. In order to prevent the surface resistance value Y from becoming too large, the above equation (Equation 4) is used.
It is indicated that it is necessary to use an electron conjugated polymer having good conductivity so as to satisfy the conditions specified in (1).

In general, as the molecular weight of the electron conjugated polymer increases, that is, as the length of the polymer chain increases, the surface resistance decreases. Further, when the cleaning material is used, the electron conjugated polymer peels off due to friction with an object to be cleaned. It becomes difficult. In order to obtain an electron conjugated polymer having a large molecular weight, specifically, a solution containing an oxidizing agent, which is a polymerization catalyst, is contained in a fiber sheet and is brought into contact with a monomer, or after the monomer is contained in a fiber sheet, a polymerization catalyst After the solution containing the oxidizing agent is brought into contact with the fiber sheet, the solution is immediately washed to remove unreacted monomers and the oxidizing agent, but not less than 1 minute, preferably not less than 2 minutes, more preferably not less than 5 minutes. By leaving the reaction to proceed, a polymer having a molecular weight sufficient to satisfy the above relational expression (Equation 4) can be obtained. When the reaction is allowed to proceed for 1 minute or longer, preferably 2 minutes or longer, more preferably 5 minutes or longer, the temperature is more preferably set to room temperature or lower.

When the entire fiber sheet is covered with the electron conjugated polymer, the charge elimination property is more excellent. However, when the above relational expression (Equation 4) is satisfied and the object of the present invention is achieved, The fiber sheet may be partially covered.
When the fiber sheet is partially covered in this way, the surface resistance refers to the surface resistance of a portion covered with the electron conjugated polymer.

The cleaning material of the present invention may be used as it is in the form of a sheet, or may be processed into another appropriate shape and used. For example, by using the sheet-like cleaning material of the present invention and forming a bag-like space, it is easy to clean,
It may be a cleaning material excellent in workability. As the bag-like space, for example, as shown in FIG. 4, it may be a glove-like that can be inserted to separate each of the five fingers, FIG.
As shown in FIG. 5, it may be in the form of a glove in the form of a mitten in which the thumb and the other four fingers can be inserted separately, or in the form of a semicircular glove in which the entire hand can be inserted. As shown in FIG. 6 , a glove and a conductive fiber sheet may be integrated. Also, besides the space where the hand can be inserted, for example,
It may be a space where a mop can be inserted, or a space where a foot can be inserted.

When the cleaning material of the present invention is formed into a glove, the conductive fiber sheet is used on at least one side of the cleaning material, and the conductive fiber sheet is used so that the surface of the conductive fiber sheet comes into contact with the object to be cleaned. Then, the object to be cleaned can be cleaned without being charged. More preferably, the conductive fiber sheet is used on both sides so that both sides can be cleaned so that it can be used for a long time.

The bag-shaped space can be formed by sewing a conductive fiber sheet or by utilizing the fusion property of the fibers constituting the conductive fiber sheet. In the former case, the use of a conductive thread as the sewing thread provides more excellent static elimination. Alternatively, after forming a bag-shaped space with a fiber sheet, the fiber sheet may be coated with an electron conjugated polymer to impart conductivity.

As described above, the cleaning material of the present invention does not damage the object to be cleaned and is excellent in cleaning property and static elimination property. Therefore, the cleaning material for a car body, table, desk, closet, cabinet, chair, etc. before painting is used. It is suitable for cleaning furniture, plastic moldings, windows, doors, floors and other places where static electricity is likely to occur due to friction.
