Description

  The present invention relates to a wiping brush material provided for the purpose of wiping dirt on the surface of a display panel or an electronic information recording disk in a production process of a television or a personal computer.

  Conventionally, brush materials that have been used for wiping display panels such as liquid crystal display panels, plasma display panels, and organic EL display panels converge a large number of synthetic resin monofilaments 1 of about 0.02 mmφ as shown in FIG. 1A. A plurality of wiping multifilament twisted yarns 2 formed by twisting are twisted to form a multifilament double twisted yarn 3, and the multifilament double twisted yarn 3 is melt-bonded as shown in FIG. 1B. A brush material 3 ′ in which the surface of the multifilament double twisted yarn 3 is impregnated into the surface layer of the multifilament double twisted yarn 3 by dipping in the inside of the multifilament double twisted yarn 3 is covered with the adhesive layer 4. ing.

  For example, the brush material 3 'composed of the three groups of multifilament double-twisted yarns is folded in half, the two folds are sandwiched by U-shaped channels, and the U-shaped channels are tightly wound around a rotating shaft to form a rotating brush. In this method, the surface of the display panel is wiped with the tip of the brush material 3 'while rotating the rotating brush while the alkaline cleaning liquid is showered on the surface of the display panel.

  Therefore, as a brush material for wiping the display panel, performance such as a uniform diffusion in the bristles of the brush material, and the bristles with the diffusion that can be touched softly on the panel surface, a strong hair, etc. However, the conventional brush material coated with the above-described adhesive material has a problem that the hair tip does not easily diffuse and the cleaning effect of the alkaline cleaning liquid is lowered.

  Further, the adhesive material is deteriorated by the alkaline cleaning liquid, and the particles of the adhesive material are peeled off and attached to the panel with the above diffusion, thereby reducing the wiping purpose.

  The present invention provides a brush material with high suitability that appropriately achieves the conditions required for the above-described display panel, or a brush material for wiping electronic information recording disks such as optical disks and magnetic disks.

  This brush material uses as a unit material a wiping multifilament twisted yarn having a structure in which a large number of monofilaments made of synthetic resin are bundled and twisted.

  On the other hand, as a means for fusing the wiping multifilament twisted yarn, a fusion multifilament having a structure in which a number of monofilaments having a melting point lower than that of the monofilament forming the wiping multifilament twisted yarn are converged and twisted A twisted yarn is formed.

  Furthermore, a plurality of the wiping multifilament twisted yarns are converged and twisted, and at the time of the twisting, the fusion multifilament twisted yarns are converged and twisted together to form a multifilament double twisted yarn. Form.

  As an appropriate example, three wiping multifilament twisted yarns are arranged and twisted at the apexes of the triangular points, and the three multifilament twisted yarns are interposed in the core portion to interleave the three yarns. Twist together with a wiping multifilament twisted yarn.

And said low-melting mono-filaments of the surface layer portion of the fusing multifilament Yogoito melted by heat, the multifilament twisted yarns cross for each拭掃in contact with the melting wear multifilament twisted yarns through the heat melting A brush material for wiping a display panel or an electronic information recording disk is formed by fusing.

  The monofilament forming the wiping multifilament twisted yarn and the monofilament forming the fusion multifilament twisted yarn are nylon, for example, 66 wiped nylon having a high melting point is used for the wiping multifilament twisted yarn. As the multifilament yarn for fusion, 6 nylon having a low melting point is used.

  Nylon has high impact resistance and chemical resistance, low moisture absorption, and is suitable as a brush material for wiping.

  As the monofilament for forming the wiping multifilament twisted yarn, one having a thickness of 0.1 mmφ or less, and suitably 0.02 to 0.06 mmφ is used.

  On the other hand, as the monofilament for forming the fusion multifilament twisted yarn, for example, one having a thickness of 0.02 to 0.06 mmφ is used, preferably more sufficiently than the monofilament forming the multifilament twisted yarn for wiping. Use a small diameter.

  Alternatively, the monofilament forming the wiping multifilament twisted yarn and the monofilament forming the fusion multifilament twisted yarn have substantially the same diameter, and are, for example, thick in the range of 0.02 to 0.06 mmφ. Select the size.

  Further, the fusion multifilament twisted yarn is smaller in diameter than the wiping multifilament twisted yarn. Alternatively, the fusion multifilament twisted yarn and the wiping multifilament twisted yarn have substantially the same diameter.

  The brush material is folded in half as described above, the folded base is sandwiched between U-shaped channels to form a channel-shaped brush, and the channel-shaped brush is spirally wound around a rotating shaft to form a rotating brush, While showering alkali cleaning liquid or the like on the surface of the display panel or electronic information recording disk, the hair brush is pressed against the surface of the display panel or electronic information recording disk while rotating the rotating brush at a rotational speed of 200 rpm to 300 rpm. Wipe and clean the surface.

  The brush material according to the present invention induces good hair tip diffusion required in panel wiping, and can exhibit the wiping effect of the diffused hair tip.

  Also, the appropriate hair strength can be obtained, and while the diffused hair tip is softly touching the panel or disk surface, the diffused hair tip is pressed against the panel surface with the appropriate waist strength to exert the wiping effect. Increase.

  Also, conventional adhesive materials such as brush materials are not deteriorated by alkali, and the problem of peeling and dispersion of the coated adhesive due to alkali deterioration and impact does not occur. To eliminate the problem of reducing the wiping purpose.

  Moreover, the problem of hindering the hair end diffusibility by restraining the wiping multifilament twisted yarn with the covering adhesive can be solved, and the tip can be sufficiently diffused to improve the wiping effect as described above. Keep the wiping function healthy until the volume is reached.

  Hereinafter, the best mode of the brush material for wiping a display panel according to the present invention will be described with reference to FIGS.

  As shown in FIG. 2A, about 60 to 150 ultrafine monofilaments 11a made of synthetic resin are converged to form a multifilament bundle, and twisted to form a wiping multifilament twisted yarn 12a. .

  On the other hand, as shown in FIG. 2B, about 20 to 50 ultrafine monofilaments 11b made of synthetic resin having a melting point sufficiently lower than that of the monofilament 11a are converged to form a multifilament bundle and twisted. A multifilament twisted yarn 12b for fusion is formed.

  As shown in FIG. 2C, the three wiping multifilament twisted yarns 12 a are converged and twisted to form a multifilament double twisted yarn 13. These three wiping multifilament twisted yarns 12a are arranged at the apexes of an equilateral triangle as shown in FIG. 3A.

  Thus, when the three wiping multifilament twisted yarns 12a are twisted, the single fusion multifilament twisted yarn 12b is inserted into the core, and the twisted yarns 12a and 12b are joined together. To form the multifilament double-twisted yarn 13.

  By inserting the fusion multifilament twisted yarn 12b between the three wiping multifilament twisted yarns 12a, a heat flow interval 21 is formed between the adjacent wiping multifilament twisted yarns 12a. The heated gas in the heating furnace is surely brought into contact with the peripheral surface of the multifilament twisted yarn 12b to be fused through the interval 21 to promote the melting.

  As shown in FIG. 3B, the multifilament double twisted yarn 13 is passed through a heating furnace at a constant speed to heat all or part of the ultrafine multifilament twisted yarn 12b, at least the monofilament 11b in the surface layer portion. At the same time, the filaments 11b are melt-fused and melted together, and at the same time, the three wiping multifilament twisted yarns 12a are bonded to each other in the monofilament 11a on the surface layer through the melted material of the monofilament 11b. A brush material 13 'is formed.

  That is, the fusion is performed in the contact region W1 in the longitudinal direction of the multifilament twisted yarn 12b for fusion and the three wiping multifilament twisted yarns 12a, and non-fused in the region W2 other than the contact fusion region W1. Form a wearing state. Reference numeral 14 denotes a fused portion in the region W1.

  The multifilament twisted yarn 12a for wiping exhibits good diffusibility in the non-bonding region W2 and improves the wiping effect.

  The ultrafine monofilament 11a forming the wiping multifilament twisted yarn 12a is made of a synthetic resin having a diameter of 0.1 mmφ or less, preferably 0.02 to 0.06 mmφ, and, as a suitable example, nylon rich in alkali resistance. About 60 to 150 monofilaments 11a having a diameter of 03 mm are converged and twisted to form the wiping multifilament twisted yarn 12a.

  On the other hand, as the monofilament 11b for forming the fusion multifilament twisted yarn 12b, for example, one having a thickness of 0.02 to 0.06 mmφ is used, and preferably the monofilament for forming the wiping multifilament twisted yarn 12a The diameter is sufficiently smaller than 11a.

Using monofilament 11b also nylon to form the fusing multifilament Yogoito 12b, both 12a, 12b and a multi-filament nylon.

  6 nylon has a melting point of 215-220 ° C. 66 nylon has a melting point of 255-260 ° C., 610 nylon has a melting point of 214-217 ° C., 612 nylon has a melting point of 213-216 ° C., 11 nylon has a melting point of 186-189 ° C., 12 The melting point of nylon is 178-181 ° C.

  As a specific example, 66 nylon having a high melting point is used for the monofilament 11a of the multifilament twisted yarn 12a for wiping, and 6 nylon having a low melting point is used for the monofilament 11b of the multifilament twisted yarn 12b for fusing.

  As another example, 66 nylon having a high melting point is used for the former 11a, and 11 nylon or 12 nylon having a low melting point is used for the latter.

  Nylon has high impact resistance and chemical resistance, low hygroscopicity, and is suitable as a brush material for wiping.

  Preferably, a monofilament that is sufficiently thinner than the monofilament 11a that forms the wiping multifilament twisted yarn 12a is used as the monofilament 11b that forms the multifilament twisted yarn 12b for fusing.

  Alternatively, the monofilament 11a forming the wiping multifilament twisted yarn 12a and the monofilament 11b forming the fusion multifilament twisted yarn 12b have substantially the same diameter, for example, a range of 0.02 to 0.06 mmφ. Select one with the same diameter.

  More preferably, the fusion multifilament twisted yarn 12b is smaller in diameter than the wiping multifilament twisted yarn 12a. For example, by selecting the number and diameter of monofilaments, the diameter of the wiping multifilament twisted yarn 12a is 0.2 to 0.6 mmφ, and the diameter of the fusion multifilament twisted yarn 12b is 0.1 to 0.3 mmφ. To do.

  Alternatively, the fusion multifilament twisted yarn 12b and the wiping multifilament twisted yarn 12a having substantially the same diameter are used.

  As shown in FIG. 5A, the brush member 13 'is folded in two so as to straddle the core member 15, and the two-fold base portion is sandwiched together with the core member 15 by the U-shaped channel 16 so that the channel-shaped brush 17 is attached. Form.

  As shown in FIG. 5B, the channel-shaped brush 17 is spirally wound around the rotary shaft 18 to form a rotary brush 19, and the hair tips of the peripheral surface of the rotary brush 19 are trimmed so that the brush material 13 'is densely arranged. The planted same rotating brush 19 is obtained.

  The bristles of the rotating brush 19 are pressed against the surface of the display panel or electronic information recording disk, and the surface of the panel or disk is rotated at a rotational speed of 200 rpm to 300 rpm while showering an alkaline cleaning solution or the like on the surface of the panel or disk. Wipe clean.

  As shown in FIG. 4, when the brush material 13 'is wiped, the monofilaments 11a at the ends of the multifilament twisted yarn 12a for wiping are sequentially joined to the fused portion 14 by the multifilament twisted yarn 12b for fusing. While separating, it effectively induces an active hair tip diffusion 20 of uniform and appropriate length at the hair tip.

  The group of monofilaments 11a in the non-fusion region W2 other than the fusion region W1 of the wiping multifilament twisted yarn 12a produces good diffusion and exhibits an effective wiping effect.

  Similarly, the multifilament twisted yarn 12b for fusion has the meaning that the monofilament 11b group in the core portion that is not fused is diffused and wiped to form the monofilament 11b group.

  The brush material 13 ′ has an appropriate bristle strength by double twisting of a plurality of multifilament twisted yarns 12 a for wiping and a multifilament twisted yarn 12 b for fusing, and sufficient hair end diffusion 20 is obtained. While touching the panel or disk surface softly, the wiping effect is pressed with moderate waist strength to enhance the wiping effect and the cleaning effect.

  Since the brush material 13 'is fused and bonded with the wiping multifilament twisted yarn 12a via the fusion multifilament twisted yarn 12b, the covering adhesive material such as a conventional brush material is deteriorated and peeled. This eliminates the problem that the dispersed and dispersed adhesive particles adhere to the panel or disk surface and reduce the wiping purpose without causing a situation of dispersion.

  Moreover, the problem of obstructing the hair tip diffusibility by restraining the wiping multifilament twisted yarn 12a with the covering adhesive can be solved, and the hair tip can be sufficiently diffused as described above to improve the wiping effect. Keep the wiping function healthy until the amount of wear is reached.

  In the above-described embodiment, the case where a single multifilament twisted yarn 12b is inserted into the core of three wiping multifilament twisted yarns 12a and twisted is shown. About this number of wiping multifilament twisted yarns 12a are used to converge and twist the plurality of wiping multifilament twisted yarns 12a and one to three fusion multifilament twisted yarns 12b. Thus, as described above, the case where the plurality of wiping multifilament twisted yarns 12a are fused via the fusion multifilament twisted yarns 12b is included.
