The shaft body side brush member 28 having a wavy step is overlapped with each other and integrated through a joint 29 by sewing, and the integrated sheet-like body forms a cylindrical shape. Thus, after overlapping both ends, a piece of brush piece 23 having a sewing portion 26 may be formed by sewing.

  As described above, when the brush piece 23 formed so that the joint 29 of the cleaning side brush member 27 and the shaft body side brush member 28 has a different distance from the shaft body 5 is used, the cleaning brush 1 for a car wash machine is The brush piece 23 is given strength and weakness, and the brush piece 23 comes into contact with and comes into contact with the vehicle body that is the surface to be cleaned with a further different pressing force. It can be dropped and removed. Therefore, the cleaning property is greatly improved.

  Further, as shown in FIG. 5A, a cleaning side brush member 67 having a plurality of divided pieces 19 formed by slits 10 at the cleaning side end portion and a shaft body side brush member 68 are formed via a joining portion 69 by sewing. The brush piece 63 made can also be used. Further, as shown in FIG. 5B, a cleaning side brush member 77 having a subdivided portion 56 formed by a subdividing machine or the like at the end of the cleaning side and a shaft body side brush member 78 are joined via a joint 79 by sewing. You may use the brush piece 73 formed in this way. Furthermore, as shown in FIG. 5C, the cleaning side brush member 87 in which a plurality of divided pieces 59 are formed by the slit 60 and the subdivided portion 66 formed by a subdividing machine or the like at the cleaning side end, and the shaft The body-side brush member 88 may be a brush piece 83 formed through a joint portion 89 formed by sewing.

  When the brush pieces 63, 73, 83 as described above are used, the washing brush 1 for a car wash machine is a surface to be cleaned by the divided pieces 19, 59 divided by the slits 10, 60 and the subdivided portions 56, 66. Since the divided pieces 19 and 59 and the fine divided portions 56 and 66 come into contact with the fine uneven portions of the vehicle body to scrape dirt, the cleaning performance is greatly improved.

  Next, the materials of the cleaning side brush members 7, 27, 67, 77, and 87 will be described with reference to FIG.

  In FIG. 6 (a), the cleaning brush members 7, 27, 67, 77, and 87 are made of a non-woven fabric 31 having a raised portion 36 formed on one side and porous polyurethane having ultrafine bubbles 32. It is formed of a heavy structure. The material as described above is manufactured by the following procedure. First, a plurality of fibers 35 are accumulated in a flat plate shape to form a cloth-like body, and a plurality of the cloth-like bodies are overlapped, and then a special needle is pierced to be entangled three-dimensionally. A nonwoven fabric 31 is formed. The manufacturing method as described above is generally called needle punching. Next, the nonwoven fabric 31 is impregnated in the polyurethane solution, thereby filling the nonwoven fabric 31 with the polyurethane solution. Next, the non-woven fabric 31 filled with the polyurethane solution is immersed in water and carbon dioxide is injected by injecting carbon dioxide into the water, so that the non-woven fabric 31 and the porous polyurethane having ultrafine bubbles 32 are obtained. A double structure comprising the base portion 33 is obtained. Next, the brushed portion 36 is formed by polishing one surface of the double structure using polishing paper or the like. Polyester is used as the material of the fiber 35, but spandex, which is also called nylon, polypropylene, urethane elastic yarn, or the like can be used alone or in combination. The fiber 35 may be either a short fiber or a long fiber. Generally, a short fiber is a fiber having a yarn length of 50 mm or less, and a long fiber is a fiber having a yarn length greater than 50 mm. The fiber 35 may be either a raw fiber or an ultrafine fiber. In general, the original yarn fiber is a fiber having a fineness of 1 dtex or more, the ultrafine fiber is a fiber having a fineness of less than 1 dtex, and 1 dtex is a fiber having a yarn length of 10,000 m and 1 g. That is. Further, the double structure may be subjected to water repellent processing by using a method such as impregnation, immersion, spraying, or the like with a fluororesin or a urethane resin.

  When the double structure is used for the cleaning side brush members 7, 27, 67, 77, 87, the double structure has porous polyurethane, so it has excellent flexibility and is a surface to be cleaned. The non-woven fabric 31 efficiently and reliably removes dirt while being in close contact with the vehicle body. Further, when the raised portion 36 is in contact with the vehicle body, the friction coefficient is improved compared to the case where the non-raised surface is in contact with the vehicle body, and the raised portion 36 is more closely attached to the vehicle body. It is possible to scrape dirt accumulated on the uneven part.

  Moreover, the washing | cleaning side brush members 7, 27, 67, 77, 87 can also use the flat nonwoven fabric 41 which consists of the some aggregate | assembly 37 like FIG.6 (b). As shown in FIGS. 6C and 6D, the assembly 37 is formed in a substantially wedge shape having a plurality of slits 42 in the longitudinal direction of the outer peripheral surface and a plurality of corners 40. It is. The nonwoven fabric 41 is manufactured by the following procedure. First, a synthetic resin such as polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyamide 6, polyamide 66, polyethylene, and polypropylene is melt-spun to obtain a raw yarn long fiber having a substantially round cross section. The obtained raw filament yarn is entangled three-dimensionally by needle punching to form a web that becomes a cloth-like body. Next, a high-pressure water stream of about 100 kg to 150 kg is applied to the web to bind the raw yarn long fibers, and the raw yarn long fibers are subjected to the high-pressure water flow, so that FIG. 6 (c) and FIG. ), A plurality of slits 42 are generated and subdivided along the longitudinal direction of the outer peripheral surface, and a plurality of subdivided ultrafine fibers 45 having corner portions 40 are formed. Next, a polymer elastic body 43 such as polyurethane is attached to the surface of the fiber 45 by using a method such as spraying, dipping, or impregnation to form a flat-plate-shaped nonwoven fabric 41 composed of the aggregate 37 in which the elastic fibers 38 are focused. . The manufacturing method as described above is generally called a hydroentanglement method. Further, the non-woven fabric 41 may be subjected to water repellent processing by using a method such as impregnation, immersion, spraying, etc. with a fluororesin, a urethane resin or the like.

  When the nonwoven fabric 41 is used for the cleaning brush members 7, 27, 67, 77, 87, since the nonwoven fabric 41 has the polymer elastic body 43, the nonwoven fabric 41 flexibly contacts the vehicle body that is the surface to be cleaned, and the fibers 45. The corners 40 of the are removed so as to scrape off dirt.

  In addition, the materials used for the cleaning brush members 7, 27, 67, 77, 87, besides the materials as described above, are excellent in adhesion to the vehicle body and have high flexibility, such as woven fabrics, knitted fabrics, A film-like resin composition or the like can be used.

  Next, materials used for the shaft body side brush members 8, 28, 68, 78 and 88 will be described.

  The shaft body side brush members 8, 28, 68, 78, and 88 are preferably made of a material having low water absorption and capable of holding a strong fur. For example, a fiber is formed by continuously spinning a polyolefin-based synthetic resin such as heat-melted polyethylene or polypropylene, and the fibers are collected on a collection net while being stretched and pressed with a hot roll. A bonded nonwoven fabric is preferably used. The method for producing a nonwoven fabric as described above is generally called a spunbond method. Polyolefin-based synthetic fibers have a water absorption rate of 0%, the fibers do not absorb water during the car wash, and the nonwoven fabric produced by the spunbond method is pressurized with a hot roll. Since the water-absorbing gap is thermocompression-bonded and the water absorption is low, strong shaving can be imparted to the shaft body side brush members 8, 28, 68, 78, 88.

  Moreover, you may use for the shaft body side brush members 8, 28, 68, 78, and 88 fabrics, such as a nonwoven fabric, a woven fabric, and a knitted fabric, which have a polytrimethylene terephthalate fiber. Polytrimethylene terephthalate fiber has a low water absorption of 0.4%. Moreover, since the molecular chain is bent in a spring shape, it has excellent shape restoring force and high elasticity. Therefore, when a fabric having polytrimethylene terephthalate fiber is used for the shaft body side brush members 8, 28, 68, 78, 88, the shaft body side brush members 8, 28, 68, 78, 88 retain strong bristle. can do. If the fabric is subjected to water repellent treatment with a fluorine resin, a silicone resin, or the like, the water absorption is further lowered, and the fur and the waist can be maintained for a long period of time.

  The materials used for the shaft body side brush members 8, 28, 68, 78 and 88 are not only the materials as described above, but also thermoplastic elastomer sheets, synthetic resin plates, synthetic resin foams having closed cells, and the like. Can be used.

  Next, the cleaning state of the brush body 2 with respect to the vehicle body, which is the surface to be cleaned, at the time of washing the washing brush 1 for a car wash machine will be described with reference to FIGS.

  As shown in the AA sectional view of FIG. 8, the brush body 2 has an attachment portion 14, an attachment portion 24, and an attachment portion 34 formed on the vehicle body. That is, the pressing force 46 is generated obliquely downward to the left from the base end portion of the shaft body side brush member 8 on the shaft body 5 side toward the cleaning side end portion of the cleaning side brush member 7. Further, as shown in the BB cross-sectional view, when the mounting portion 14 and the mounting portion 24 are formed on the vehicle body, in a direction perpendicular to the longitudinal direction of the shaft body 5 toward the end of the brush body 2 with respect to the vehicle body. A pressing force 47 is generated. Further, as shown in the CC cross-sectional view, when the mounting portion 4, the mounting portion 14, and the mounting portion 24 are formed on the vehicle body, the end portion of the brush body 2 from the mounting portion 24, that is, the shaft body side brush member 8 is formed on the vehicle body. A pressing force 48 is generated obliquely downward to the right from the base end portion on the shaft body 5 side toward the cleaning side end portion of the cleaning side brush member 7.
