Definitions

  • the present invention relates to cleaning materials suitable for cleaning objects which are liable to generate static electricity by the friction with a cloth-like cleaning material, such as automobile bodies before coating, furniture including tables, desks, chests of drawers, cabinets and chairs, plastic moldings, windows, doors and floors.
  • a cloth-like cleaning material such as automobile bodies before coating, furniture including tables, desks, chests of drawers, cabinets and chairs, plastic moldings, windows, doors and floors.
  • the part to be coated should be cleaned beforehand so as to avoid inferior finishing due to the dust collected from the atmosphere and attached to the surface of the part.
  • conventional cleaning sheets made of a woven fabric or a nonwoven fabric can clean the part to be coated temporarily, they are not practical since static electricity is liable to be generated by the friction between the cleaning sheets and the part to be coated, thus gathering dust from the atmosphere. Therefore an ion neutralizing device and a cloth applied with an adhesive on its surface are used together.
  • the cleaning method of eliminating static electricity with an ion neutralizing device and wiping with a cloth having an adhesive property on its surface is troublesome, and besides the ion neutralizing device is expensive.
  • cleaning sheets comprising conductive fibers including carbon black or metal powders, or metal-plated conductive fibers have been used.
  • the former is insufficient in terms of fiber strength and durability whereas the latter tends to damage the object being cleaned.
  • the object of the present invention is to solve the above-mentioned problems and to provide cleaning materials having excellent durability and operability without damaging the object to be cleaned nor generating static electricity.
  • a cleaning material comprising a fiber sheet which comprises a conductive fiber coated with an electron-conjugated polymer (a polymer having conjugated electrons), wherein the adhesion ratio of the electron-conjugated polymer to the fiber sheet is 0.05 to 3 weight %, and the relationship between the adhesion ratio X (weight %) and the surface resistance Y ( ⁇ / ⁇ ) of the fiber sheet which comprises a conductive fiber coated with an electron conjugated polymer satisfies the following formula (P) : log Y ⁇ -0.8X + 5 and the average diameter of the fiber comprised in the fabric sheet is 10 ⁇ m or less.
  • P log Y ⁇ -0.8X + 5
  • the cleaning materials of the present invention comprise a conductive fiber coated with an electron conjugated polymer and the electron conjugated polymer is soft enough to avoid damaging the object to be cleaned. Also, static electricity can be eliminated by corona discharge at the time of cleaning the object to be cleaned, and cleaning can be conducted without generating static electricity on the object to be cleaned. Further, since electron conjugated polymers just cover the surface of a fiber without deteriorating the fiber strength, cleaning materials having excellent durability can be provided. Moreover, since cleaning materials of the present invention can clean and eliminate static electricity by just wiping the object to be cleaned, they provide excellent operability.

  • FIG. 6 is a schematic depiction of a further embodiment of an application of the cleaning materials of the present invention.
  • Cleaning materials of the present invention comprise a fiber sheet comprising a conductive fiber coated with an electron conjugated polymer.
  • fibers coated with an electron conjugated polymer include natural fibers such as silk, wool, cotton and linen, regenerated fibers such as rayon fibers, semi synthetic fibers such as acetate fibers, and synthetic fibers such as polyamide fibers, polyvinyl alcohol fibers, acryl fibers, polyester fibers, polyvinylidene chloride fibers, polyvinyl chloride fibers, polyurethane fibers, polyethylene fibers, polypropylene fibers and aromatic polyamide fibers.
  • conjugated fibers comprising a plurality of resin components of sheath & core type or a side-by-side type can be used as well.
  • Cleaning materials comprising fine fibers obtained from conjugated fibers capable of further generating fine fibers having a diameter of 9 ⁇ m or less by a physical and/or a chemical treatment (hereinafter referred to as "fiber capable of further generating fine fibers”) can be used preferably because such cleaning materials exhibit excellent elimination of static electricity by corona discharge, excellent cleaning of the object to be cleaned and retaining of the dust, do not tend to damage the object to be cleaned and have excellent strength.
  • fiber capable of further generating fine fibers include embodiments such as an island-in-sea type conjugated fiber having a section comprising a component (A) with another component (B) located therein like islands as illustrated in FIG.
  • a multiple-bimetal type conjugated fiber having a section comprising a component (A) and another component (B) laminated alternately to form layers as illustrated in FIG. 2 and an orange section-type conjugated fiber having a sectional configuration comprising a component (A) divided with another component (B) radially as illustrated in FIGs. 3(a) or 3(b).
  • multiple-bimetal type conjugated fibers and "orange" type conjugated fibers are preferable since fine fibers yielded therefrom have a modified cross-sectional shape such as a trapezoid-like shape and a sector shape to excellently facilitate cleaning and elimination of static electricity.
  • Known methods can be used to yield fine fibers from such fibers capable of further generating fine fibers.
  • Examples of common methods include physical treatment methods such as applying mechanical stress to a fiber capable of further generating fine fibers as illustrated in FIGs. 2, 3(a), 3(b) to divide components (A) and (B) at their borders to obtain fine fibers of component (A) and (B), or chemical treatment methods such as removing a component (A) with a solvent capable of dissolving only a component (A) or with a chemical capable of decomposing only a component (A) to an island-in-sea type conjugated fiber as illustrated in FIG. 1 to obtain fine fibers of the component (B).
  • the physical treatment methods and chemical treatment methods can be used together as needed.
  • the chemical treatment methods can be applied to fibers capable of further generating fine fibers as illustrated in FIGs. 2, 3(a), 3(b) to obtain fine fibers of one component.
  • the physical treatment methods can be applied to island-in-sea type conjugated fibers as illustrated in FIG. 1 in case the sea component (A) comprises a resin component pulverizable by a mechanical stress.
  • Resin components of such fibers capable of further generating fine fibers may be a combination of two or more.
  • a combination of two components include a polyamide resin and a polyester resin, a polyamide resin and a polyolefin resin, a polyester resin and a polyolefin resin, polyester resin and a polyacrylonitrile resin, a polyamide resin and a polyacrylonitrile resin, and a polyolefin resin and a polyacrylonitrile resin.
  • a fiber sheet comprising a cleaning material contains 5 weight % or more of fine fibers yielded from such fibers capable of further generating fine fibers. Since the greater the content of fine fibers, the better both the static electricity elimination property and the wiping property of the cleaning material become, it is more preferable that the ratio of fine fibers yielded from the fibers capable of further generating fine fibers is 50 weight % or more, and it is most preferable that the ratio is 90 weight % or more.
  • the diameter of fibers comprising a fiber sheet used in the present invention it is necessary to have the average fiber diameter of 10 ⁇ m or smaller. If the average fiber diameter is greater than 10 ⁇ m, it is impossible to provide sufficient static electricity elimination property or wiping property. Since good static electricity elimination property and wiping property can be provided without deterioration of mechanical strength or durability with the average fiber diameter in the range of 10 to 0.1 ⁇ m, it is preferable.
  • the diameter of the round shape which has a sectional area the same as that of the modified cross-sectional shape is calculated, and the value is referred to as the "fiber diameter" herein.
  • the length of fibers which constitute a fiber sheet is, in general, 1 to 160 mm. It is particularly preferable to have the average fiber length in the range of 20 to 110 mm, since a shorter length may cause the problem of a tendency toward falloff of fibers, or a longer length may cause the problem of deterioration of property of eliminating static electricity due to a reduced number of ends of fibers in the fiber sheet.
  • the “average fiber diameter” and the “average fiber length” herein denote the average value of 100 fibers collected by random sampling.
  • a drawn fiber is used preferably as the fibers for the fiber sheets with respect to durability.
  • As to the drawing ratio 1.5 to 5 times is preferable.
  • a conductive fiber is formed by coating the above mentioned fibers with an electron conjugated polymer. If a fiber sheet is formed after coating fibers with an electron conjugated polymer, the electron conjugated polymer may be damaged at the time of the fiber sheet formation. Therefore it is preferable to coat a fiber with an electron conjugated polymer after forming a fiber sheet. In this case, a conductive fiber not completely coated with an electron conjugated polymer may be formed.
  • the adhesion ratio of an electron conjugated polymer to a fiber sheet needs to be 0.05 to 3 weight %. It is not preferable to have an adhesion ratio of smaller than 0.05 weight %, because the static electricity eliminating property of the obtained cleaning material may deteriorate. Further, it is not preferable to have an adhesion ratio of more than 3 weight %, because the flexibility of the obtained cleaning material may deteriorate to ruin the cleaning operability and the electron conjugated polymer becomes liable to fall off due to the friction against the object to be cleaned.
  • Adhesion ratio X (weight %) ((electron conjugated polymer weight)/(electron conjugated polymer weight + fiber sheet weight)) ⁇ 100.
  • fiber sheets for cleaning materials of the present invention include nonwoven fabrics, woven fabrics and knit fabrics.
  • nonwoven fabrics are preferable because static electricity can be well eliminated by corona discharge by increasing the number of fiber ends at the surface of the fabric by orienting the fibers in the direction of the thickness, and by holding a three-dimensional space, dust gathered from the object to be cleaned can be retained in the space.
  • Such nonwoven fabric with the fibers oriented in the thickness direction thereof can be obtained by methods such as preparing a fiber web by a wet method and a dry method including a carding process and an air-laid process, or a direct method including a spun-bonded process and a melt-blown process, followed by an entangling treatment with a fluid flow such as water or a mechanical force such as a needle punching. Since the former fluid flow entangling treatment provides a nonwoven fabric superior with respect to uniformity and strength, it is more preferable.
  • a cross-laid web cross-layered with respect to the longitudinal direction of the fiber web so as to improve the strength in the width direction of the fiber web, and thus cleaning materials having an excellent shape stability and operability can be provided.
  • fine fibers can be both obtained and also entangled if the above mentioned mechanical force such as a fluid flow or a needle punching is applied to a fiber web containing the above mentioned multiple-bimetal type conjugated fibers or orange type fibers capable of further generating fine fibers without the need of having a further process to yield fine fibers, such method of forming a nonwoven fabric is efficient. Further, since entanglement of fine fibers provides a dense structure, dust can be retained well.
  • a nonwoven fabric it is preferable to improve strength and wearing resistance property of a nonwoven fabric by fixing with a binder of an emulsion-type, a solution-type or a powder-type, or by heat-binding intersections of fibers of the nonwoven fabric.
  • fix partially in order not to deteriorate the static electricity elimination property or wiping property, it is preferable to fix partially.
  • the area per one fixed part is 0.01 to 5 mm 2 and the total fixed area based on the total area (the area observed two-dimensionally as if the surface of the nonwoven fabric is flat) of the nonwoven fabric is 5 to 50 % with respect to the improvement of strength and wear resistance property by the fixation without deteriorating the static electricity elimination property or wiping property.
  • methods of fixation methods of partially fixing a nonwoven fabric by means of an embossing roll or an ultrasonic wave is more preferable since they do not cause falloff of a binder during the use of the cleaning material, unlike a nonwoven fabric fixed with a binder, to provide an excellent cleaning property.
  • a layered fiber web having two layers or a three layers structure can be formed by a heat treatment with a fiber web containing heat-adhesive fibers on one side or as the middle layer.
  • a nonwoven fabric is formed by entangling fibers of a fiber web by a fluid flow such as a water flow, by introducing a support such as a coarse net of ca. 0.29 mm opening (50 mesh) or larger made of metal or plastic and a corresponding porous plate, the water flow is reflected at parts where the net or porous plate exists, and since fibers are pushed aside by the reflected water flow at parts where the net or porous plate exists as well as entangle with each other, perforations are formed through the thickness direction of the fiber sheet at the parts corresponding to the parts where the net or porous plate exists.
  • a nonwoven fabric formed in such manner is referred to as a "nonwoven fabric having perforations”.
  • the nonwoven fabrics having perforations have a structure that the entangled fiber bundles are crossed with each other, and fiber bundles entangle at points of intersections. Since the nonwoven fabrics having perforations collect dust from the side walls of the perforations and keep them inside of the sheet, they have an advantage of the excellent dust retention property. In the case such perforations are formed in a nonwoven fabric by a water flow, the producing conditions are not particularly limited except the support.
  • nonwoven fabrics having perforations can be formed by jetting water flow one or more times to one side or both sides of the fiber web from a nozzle plate with nozzles having a diameter of 0.05 to 0.3 mm, located with an interval of 0.2 to 3 mm aligned in a row or in a plurality of rows regularly or irregularly.
  • the jetting pressure of the water from nozzles can be about 1 to 30 MPa (10 to 300 kg/cm 2 ).
  • fiber sheets used in the present invention are porous, almost the entire region of a fiber sheet can be coated with an electron conjugated polymer. Since the electron conjugated polymers can adhere tightly to a fiber sheet, they provide excellent durability. Further since they are very flexible, wiping and static electricity elimination can be conducted without damaging the object to be cleaned.
  • a 10 % modulus strength for the obtained cleaning materials of the present invention of 0.5 Kg/5 cm width or more in both the longitudinal direction and widthwise direction with the above mentioned various processing methods of fiber sheets to provide an excellent shape retention property and operability of the cleaning material in use.
  • nonwoven fabrics formed by laminating a parallel web in which fibers are oriented to the longitidinal direction of the fiber web and a cross-laid web in which fibers are crossed by a cross-layer, and the above mentioned nonwoven fabrics having "perforations" are particularly preferable.
  • the surface resistance of a cleaning material obtained by coating an electron conjugated polymer is approximately 1 ⁇ 10 5 ⁇ / ⁇ or less because a surface resistance over 1 ⁇ 10 5 ⁇ / ⁇ deteriorates the property of eliminating static electricity. It is more preferable that the surface resistance is 1 ⁇ 10 4 ⁇ / ⁇ or less.
  • Examples of coating methods with an electron conjugated polymer include a method of applying to a fiber sheet a solution containing an oxidant which is a polymerization catalyst such as ferric chloride (FeCl 3 ) and cupric chloride (CuCl 2 ) followed by contacting with a raw monomer for polymerization, and a method of first applying a raw monomer to a fiber sheet followed by contacting with a solution containing an oxidant which is a polymerization catalyst such as ferric chloride (FeCl 3 ) and cupric chloride (CuCl 2 ).
  • a method of contacting with a monomer when the monomer is in the liquid state, the monomer can be applied to a fiber sheet by soaking, coating or spraying. When the monomer is in the gas state, a fiber sheet can be placed in a container filled with the monomer gas.
  • Polymerization catalysts can be applied to or contacted with a fiber sheet by soaking, coating or spraying.
  • Examples of such monomers which can form electron conjugated polymers include acetylene, benzene, aniline, phenyl acetylene, pyrrole, furan, thiophene, indole and derivatives of these monomers having at least one substituent selected from the group consisting of allyl, aryl and alkyl.
  • pyrrole is preferable since it has an excellent conductivity and polymerizing property, and an excellent static electricity eliminating property and durability.
  • the formula (P) suggests that if too much of the electron conjugated polymer is adhered, flexibility of the obtained cleaning material deteriorates to lower the cleaning ability and further the electron conjugated polymer tends to fall off due to the friction against the object to be cleaned, which is not preferable. Thus a smaller adhesion amount is preferable, but in this case, an electron conjugated polymer having a good conductivity to satisfy the condition stipulated in the formula (P) should be used so as not to allow the surface resistance Y of the cleaning material to become too large.
  • a polymer having a molecular weight sufficient to satisfy the relationship defined in the above mentioned formula (P) can be obtained.
  • the temperature during the polymerization for one minute or more preferably for two minutes or more, further preferably for five minutes or more, room temperature or below is further preferable.
  • a fiber sheet can be coated partially.

  • the above mentioned conductive fiber sheets need to be applied in at least one side of the cleaning material so that the conductive fiber sheet side comes in contact with an object to be cleaned for cleaning without generating static electricity. It is more preferable to apply the above mentioned conductive fiber sheet to both sides so that both sides of the glove can be used in cleaning for long time usage.
