Definitions

  • This invention relates to a painting brush used for applying a coating material.
  • conventional painting brushes use as their bristles chemical fiber monofilaments outstanding in quality, stability of supply and the like.
  • Such conventional brushes using chemical fibers have bristles made up of straight monofilaments alone.
  • the conventional brush having straight bristles alone as described above can pick up and hold only a small amount of coating material. This may be the reason that, in the straight bristles, the monofilaments come into close contact with each other and so reduce the space for holding the coating material between monofilaments.
  • the brush disclosed in Japanese Unexamined Utility Model 6-7983 is known as a brush that overcomes this problem.
  • This conventional brush has straight bristles each having recesses formed in its surface so that the coating material is held in the recesses to increase the amount picked up.
  • the formation of the recesses in the surface of the straight bristles cannot allow a satisfactory amount of the coating material to be picked up. This is because, since a monofilament is naturally thin, even if recesses are formed in such a thin monofilament, the space created by the recesses is not as much as expected, resulting in less of an increase in the amount of coating material held in each monofilament. In either case, the conventional painting brushes having straight bristles alone have the problem of the incapability of ensuring that a sufficient amount of coating material will be picked up.
  • a painting brush having bristles according to the present invention is characterized in tat the bristles comprise straight chemical-fiber monofilaments and wavy chemical-fiber monofilaments.
  • the wavy monofilaments are included among the bristles in a mixing-proportion of from 10% to 80%.
  • the bristles include the straight chemical-fiber monofilaments, the wavy chemical-fiber monofilaments and animal hair.
  • the mixing of straight monofilaments and wavy monofilaments makes it possible to increase the amount of coating material picked up while maintaining excellent bundling of bristles. As the amount of coating material picked up increases in this manner, the amount of coating material released increases, resulting in improvement in working efficiency of the coating operation.
  • FIG. 1 is an enlarged view of a wavy monofilament.
  • FIG. 2 is a table showing the monofilament dimensions and the mixing proportion for each experimental brush in the present invention.
  • FIG. 3 is a front view of a printing brush.
  • FIG. 4 is a table showing the results of experiment 1.
  • the painting brush is provided with a bundle of bristles made up of a mixture of straight monofilaments of chemical fiber and wavy monofilaments of chemical fiber.
  • polybutylene terephthalate can be used to form the monofilaments for the bristles.
  • the type of resin can be selected with reference to the firmness or the like required for the use of the brush.
  • the brush is fabricated for applying a water-based coating material, almost all resins can be used.
  • the brush is fabricated for applying an oil-based coating material including a solvent, the available resins are limited to those unaffected by the solvent.
  • the wavy filaments in this embodiment means filaments formed in wavy configuration as illustrated in FIG. 1 .
  • straight monofilaments of chemical fiber are clamped between a pair of wavy members at a temperature at which the clamped monofilament becomes soft to some degree.
  • the wavy monofilaments thus obtained and the straight monofilaments are mixed together to form the bristles 1 shown in FIG. 3 .
  • the configuration of the wavy monofilament subjected to the waving process is designated as “wavy” and the configuration of the straight monofilament is designated as “straight”.
  • the amount of monofilaments used for each bundle of bristles 1 was determined such that the experimental brushes No. 1 to No. 4 were identical in the size of the bundle of the bristles 1 .
  • the length shown in FIG. 2 means the length of the monofilaments forming the bristles.
  • each of the experimental brushes No. 1 to No. 4 uses a combination of monofilaments of different length. In this manner, the monofilaments of different length are combined to form the bristles 1 in order to prevent the leading ends of the monofilaments from spreading out, to ensure improved bundling of the bundle of bristles.
  • a handle 2 is attached to the bristles 1 thus fabricated to form a brush as shown in FIG. 3 .
  • the bristles 1 thus fabricated have a leading-end width W 2 greater than the handle-end width W 1 .
  • the amount picked up means the weight of the coating material held in the bristles when the bristles are dipped in the coating material under certain conditions.
  • the amount released means the weight of the coating material released from the bristles onto the coated face when the coating material held in the bristles is applied to the face to be coated. The amount picked up and the amount released are measured by the change in the weight of the brush.
  • the conventional brush has a bundle of bristles made up of PBT-made straight monofilaments alone.
  • the thickness and the length of the bundle of bristles of the conventional brush are the same as those of the experimental brush No. 2 .
  • the amount picked up and the amount released are greater in the experimental brushes No. 1 to No. 4 than in the conventional brash.
  • the fact that the amount released is large means that a wide area is coated by the brush dipped only one time in the coating material. Accordingly, the use of the brush of the embodiment makes it possible to reduce the number of dips of the brush in the coating material as compared with the use of the conventional brush to improve the working efficiency in coating.
  • the reason why the amount picked up of the experimental brushes No. 1 to No. 4 is greater than that of the conventional brush is that the waves of the wavy monofilament create gaps in the bristles suitable for holding the coating material and the coating material is held in the gaps.
  • the experimental brush No. 4 with the highest mixing proportion, 50%) of the wavy monofilaments shows an increase in the amount picked up and the amount released. It can be judged from this that as the proportion of wavy monofilaments is increased, the volume of the gaps between the monofilaments is increased, thus increasing the amount of coating material held in the gaps, in turn increasing the amount picked up.
  • the spreading out of the leading ends of the bristles may make the coating operation difficult. For example, when the coating material is applied to an area close to the boundary between two coated areas exactly along the boundary, the spreading bristles are apt to cross the boundary, resulting in the coated face extending beyond the boundary. In this manner, a brush with bristles with the spreading leading-ends is hard to use. However, when the coating material is applied quickly to a wide area, a brush with the spreading leading-ends is useful.
  • the mixing-proportion of the wavy monofilaments is desirably adjusted in accordance with the intended use.
  • the most suitable mixing-proportion of the wavy monofilaments varies with the viscosity, the surface tension and the like of the coating material used, but, in the case of it being more than 80%, the leading end of the bristles may possibly spread out too much, leading to inferior working efficiency.
  • the amount of wavy monofilaments is below 10%, the amount picked up notably decreases, thus giving rise to the need for repeatedly dipping the brush in the coating material many times to coat the area. Accordingly, it is understood that a suitable condition is a mixing-proportion of wavy monofilaments ranging from 10% to 80%.
  • the bristles including animal hair basically have the advantage of a large amount picked up of the coating material, but also the disadvantage of sticking together caused by the water-based coating material.
  • the animal hair is mixed and bound together with the chemical-fiber straight monofilaments and wavy monofilaments, whereby the animal hairs are able to be kept out of contact with each other to prevent the resin from making the animal hairs stick together. For this reason, animal hair can be used for a water-based coating material.
  • the desirable proportion of animal hair is equal to or less than 50%.
