Description

  The present invention relates to a brush having a hair material made of a synthetic resin monofilament and used for cleaning, cleaning, liquid application, and the like.

  There are various kinds of conventional brushes of this type, and the bristle material constituting the briquettes is made of a chemical fiber bristle material, and is formed so as to be gradually tapered toward the tip of the bristle material. There is known a technique in which a large number of fine recesses are formed on the surface so that the interstitial liquid between the hair materials is easily collected (Patent Document 1).

Japanese Patent No. 2879424

  With the technique described in the above-mentioned conventional Patent Document 1, liquid components such as a polishing agent can be retained to some extent in a fine recess, but it is not sufficient. In addition, there is a problem that the liquid once retained in the recess is not easily exchanged with the liquid outside the recess, and the liquid remains in the recess. In addition, there is a problem that it is necessary to improve the frictional force of the bristle material in order to efficiently scrape off the dirt adhered to the surface to be cleaned.

  An object of this invention is to provide the brush excellent in the scraping performance of dirt, and holding | maintenance performance of liquids, such as a washing | cleaning liquid, in view of the said point.

  In the invention according to claim 1, in the brush used for painting or the like, the brush has a brush portion formed by bundling hair materials and a handle portion, and the brush portion is in the longitudinal direction of the outer peripheral surface. It has a feature in that it has a hair material made of a synthetic resin monofilament in which concave portions or / and convex portions are spirally formed. Accordingly, since the frictional force is increased by the contact of the concave portion or convex portion with the surface to be cleaned, the dirt can be scraped out efficiently, and the liquid such as the cleaning liquid is held by the spiral concave portion or convex portion at the time of cleaning. Therefore, the cleaning performance is improved. In addition, when used as a paint brush, the spiral recesses or protrusions hold the paint and the liquid does not stay, and new liquids are successively held in the recesses or protrusions. It is possible to prevent dripping and to apply the paint evenly and uniformly.

  The invention of claim 2 is characterized in that, in the invention of claim 1, the hair material made of synthetic resin monofilament has spiral concave portions or / and convex portions arranged continuously or intermittently. Therefore, when the concave portions or the convex portions are continuously arranged, the number of surfaces capable of holding the liquid increases, so that the liquid holding performance is improved, and the cleaning performance and the coating performance are improved. In addition, when the concave portions or the convex portions are intermittently arranged, the edge portion due to the concave portions or the convex portions increases, so that the dirt can be scraped out more efficiently.

  In the invention of claim 3, in the invention of claim 1 or 2, the bristle material made of synthetic resin monofilament has at least two of the three directions of right-handed, left-handed and straight directions. It is characterized by being arranged in a combination of more than directions. Therefore, since the edge part of a recessed part or a convex part comes to exist in various places, this edge part comes in contact with the stain | pollution | contamination of a to-be-cleaned surface from various angles, and a cleaning performance improves significantly.

  The invention of claim 4 is characterized in that, in the invention of any one of claims 1 to 3, the thickness of the hair material made of synthetic resin monofilament is made uniform or non-uniform. Therefore, when the thickness of the synthetic resin monofilament is uniform, the looseness of the brush becomes strong, so that the dirt scraping performance is improved. Further, when the thickness of the synthetic resin monofilament is not uniform, the surface area of the synthetic resin monofilament, that is, the contact area with dirt is increased, so that the dirt removal performance is improved and the retention performance of a liquid such as a cleaning liquid is improved. Therefore, the cleaning performance is also improved.

  According to the first aspect of the present invention, the liquid can be held and the dirt can be scraped out by the concave portion or the convex portion, so that the cleaning performance is improved. In the invention of claim 2, the liquid holding performance and the cleaning performance can be further improved by arranging the concave and convex portions continuously or intermittently. In the invention of claim 3, the cleaning performance can be drastically improved by the edge portion of the concave portion or the convex portion. In the invention of claim 4, the cleaning performance can be improved by making the thickness of the hair material uniform or non-uniform.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an example of a brush according to the present invention. In the brush 10, a handle portion 12 and a brush portion 11 are connected by a joint portion 13. The brush portion 11 is made of a synthetic resin monofilament brush bristle material and is implanted in the joint portion 13. The brush 10 is used for cleaning, cleaning, liquid application, and the like, and the brush bristle material used for the brush 10 of the present invention has the following characteristics.

  FIG. 2A shows a perspective view of the brush bristle material according to the first embodiment of the present invention. The brush bristle material 1 has a uniform thickness over the entire length, and is made of polyethylene, polypropylene, polystyrene. Polyolefin resin fibers such as polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, etc., polyamide resin fibers such as nylon 6, nylon 66, nylon 610, nylon 612, acrylic fibers, fluorine fibers, urethane It consists of synthetic resin monofilaments, such as a fiber and a silicon fiber, and the recessed part 2 is helically and continuously formed in the longitudinal direction of the surface as shown in the figure.

  FIG. 2B shows an example in which, instead of the concave portion 2, the convex portion 3 is continuously provided on the outer peripheral surface of the brush bristle material 1 in the same spiral manner. In addition, as a manufacturing method of the bristle material 1 for brushes of this embodiment, synthetic resin is heated and melt-spun, and abrasive paper (not shown) such as sandpaper is applied to the outer peripheral surface of the fiber at a predetermined temperature. The fiber may be wound up while forming the concave portion 2 or the convex portion 3 and twisting. Further, it is possible to form by combining extrusion and twisting, and if the die shape is made uneven, the concave portion 2 and the convex portion 3 can be formed at the same time.

  Moreover, if the outer diameter of the synthetic resin monofilament which forms the bristle material 1 for brushes is 0.05 mm or more, it can be manufactured freely. Furthermore, if each twist angle of the spiral recessed part 2 and the convex part 3 is 20 degrees or less with respect to the longitudinal direction of a synthetic resin monofilament, it can manufacture efficiently. In addition, as the depth of the concave portion 2 is increased, the performance of holding a liquid such as a cleaning liquid is improved. However, if the depth is too deep, the waist is remarkably weakened or the synthetic resin monofilament is cut when it is produced. Therefore, it is desirable to keep it to 50% or less with respect to the major axis of the cross section of the synthetic resin monofilament.

  In addition, the higher the height of the convex portion 3 is, the higher the retention performance of a liquid such as a cleaning liquid is. However, if the height is too high, the adjacent convex portion 3 is formed when the brush portion 11 is formed with a large number of brush hair materials 1. Since the liquid is held in between and the outflow of liquid from the bristle material 1 for brushes is remarkably deteriorated, the height of the convex portion 3 is preferably 50% or less with respect to the major axis of the cross section of the synthetic resin monofilament. .

  Since the bristle material 1 for brushes in this embodiment is configured as described above, when it is used for cleaning brushes or the like, the concave portion 2 or the convex portion 3 is a surface to be cleaned (not shown) or the like. Since the frictional force is increased by contacting the surface, dirt can be scraped out efficiently, and the liquid such as the cleaning liquid is held by the spiral concave portion 2 or the convex portion 3 at the time of cleaning. improves. Moreover, since the spiral recessed part 2 or the convex part 3 can prevent that a liquid component accumulates in the recessed part 2 or the convex part 3 excessively in spiral shape, it can hold | maintain a new liquid part sequentially. In addition, when the brush bristle material 1 in the present embodiment is used for painting brushes, the spiral concave portion 2 or the convex portion 3 holds the paint, so that the paint can be prevented from flowing down, and the paint can be applied evenly and uniformly. Can be applied.

  In this embodiment, as shown in FIGS. 2 (a) and 2 (b), since the concave portion 2 and the convex portion 3 are continuously arranged, the number of surfaces capable of holding the liquid is increased, whereby the liquid As a result, the cleaning performance and coating performance can be improved. Moreover, in this embodiment, since the thickness of the synthetic resin monofilament which forms the bristle material 1 for brushes is formed substantially uniform, the hair becomes stronger and the dirt scraping performance is improved. In the above-described embodiment, an example in which one recess portion 2 and one protrusion portion 3 are provided is shown. However, a plurality of recess portions 2 and protrusion portions 3 may be provided according to the viscosity of the cleaning liquid or paint used.

  Further, as shown in FIGS. 3A and 3B which are the second embodiment of the present invention, the spiral concave portion 2 and the convex portion 3 are intermittently provided on the outer peripheral surface of the brush bristle material 1. Anyway. In this case, since the edge part of the recessed part 2 or the convex part 3 increases, dirt can be scraped out more efficiently. Moreover, when the bristle material 1 for brushes in 2nd Embodiment is used for the brush for coating, since the fall of the coating material with which the edge part was hold | maintained can be prevented, it can have the high retention performance of a coating material.

  Moreover, in 1st Embodiment and 2nd Embodiment, it is also possible to form the recessed part 2 and the convex part 3 of the bristle material 1 for brushes by making only the right twist or only the left twist. As described above, according to the first embodiment and the second embodiment, the edge portion of the concave portion 2 or the convex portion 3 comes to exist at various locations, and therefore the edge portion is cleaned from various angles. It comes in contact with the dirt on the surface, and the cleaning performance is dramatically improved.

  FIG. 4 shows a perspective view of the bristle material for a brush according to the third embodiment of the present invention, in which concave portions or convex portions are arranged in a combination of at least two directions of right twist, left twist, and straight direction. However, since other configurations and materials are the same as those in the first embodiment, description thereof is omitted. FIG. 4A shows an example in which a left-handed concave portion 2 and a right-twisted concave portion 2 are continuously provided on the outer peripheral surface of the brush bristle material 1, and FIG. FIG. 4C shows an example in which a left-handed convex part 3 and a right-handed convex part 3 are continuously provided on the outer peripheral surface of FIG. FIG. 4D shows an example in which the left-handed convex part 3, the linear convex part 3 a, and the right-handed convex part 3 are continuously provided. .

  As described above, according to the third embodiment, the edge portion of the concave portion 2 or the convex portion 3 comes to be in various places, so that the edge portion comes into contact with dirt on the surface to be cleaned from various angles. Thus, the cleaning performance is greatly improved. Moreover, since liquids, such as a washing | cleaning liquid and a coating material, are hold | maintained at an edge part, it can have a high liquid holding performance.
