Description

  The present invention relates to a washing piece for a car wash used as a brush for a car wash.

  As a brush for a car wash machine, a car wash brush (see, for example, Patent Document 1) in which a brush is attached to each of a plurality of circumferential positions on the outer periphery of the rotating shaft along a spiral line on the outer periphery of the rotating shaft, or an outer periphery of a rotating body A rotating brush (for example, refer to Patent Document 2) of a car wash apparatus in which a washing body is attached in a disc shape or spirally while being shifted in the axial direction, and a plurality of sheet-like washing bodies are folded into two folded states, Attach the end opposite to the bending peak so that the end is parallel to the rotation axis of the cleaning machine, and so that a plurality of cleaning bodies are positioned radially from the rotation axis when viewed in the axial direction of the rotation axis. Car wash brush made (for example, refer to Patent Document 3), and car wash brush formed by laminating a plurality of brush fabrics having a rotating shaft inserted through the center of the cloth (for example, see Patent Document 4) Or multiple rectangular sheets A car wash in which a plurality of cleaning bodies are arranged radially from the rotating shaft as viewed in the axial direction of the rotating shaft. A brush (see, for example, Patent Documents 5 and 6) is disclosed.

  As washing pieces for car wash machines used for these brushes, non-woven fabrics, woven fabrics, synthetic resin foams, artificial leather, film-like resin sheets, elastomer sheets and the like (for example, see Patent Documents 3 and 4) are disclosed. Furthermore, a car wash brush (e.g., see Patent Document 7) formed of a three-dimensionally knitted and woven three-dimensional net material, and a washing body for a car wash machine made of tricot knitted fabric having napping (e.g., Patent Document 8) is disclosed.

  Non-woven fabrics, woven fabrics, artificial leather, film-like resin sheets, elastomer sheets, etc., give the necessary strength to increase rigidity and make it difficult to bend. There is a problem that it is difficult to drop. Further, since the so-called place for holding dirt is narrow, there is a high possibility that the vehicle will be re-contaminated by the dirt once transferred to the brush. Furthermore, if a film-like resin sheet or the like has a required strength, the rigidity becomes high, and there is a possibility that the surface of the vehicle body may be damaged by washing.

  Further, a washing body made of a tricot knitted fabric is less stiff than a synthetic resin foam, artificial leather, a film-like resin sheet, and an elastomer sheet, and is difficult to impart rigidity. Further, compared to artificial leather, film-like resin sheets, and elastomer sheets, it tends to lose shape due to long-term use, and there is a concern about shape retention compared to these sheets. Furthermore, since the knitted fabric is composed of infinite length long fiber fiber bundles, if the fiber bundle frays from the knitted fabric and gets caught in the car body during a car wash, the entire knitted fabric is pulled and pulled by the caught fiber bundle. May occur.

  Synthetic resin foam has high rigidity when it has the required strength, and has a large impact sound when washing a car, especially when the passenger is still in the car, giving the passenger anxiety and discomfort. It might be.

  The cleaning characteristics required for a washing piece for a car wash machine include the ability to scrape off dirt, the ability to scrape dirt, and the ability to knock off dirt. In the conventional cleaning piece, the higher the rigidity, the better the ability to scrape dirt and the ability to knock off dirt. However, as mentioned above, the one with high rigidity is hard to bend, so it is difficult to remove dirt on the dents. There is a problem. On the contrary, when the rigidity of the cleaning piece is lowered, the ability to scrape dirt is improved. In this case, however, there arises a problem in the dimensional stability, durability and strength of the cleaning piece.

  An example of a car wash machine will be described with reference to FIG. 1. A car wash machine 99 includes a portal frame 100 that moves in the front-rear direction of the vehicle body, and rotating brushes 104 and 104 attached to the left and right legs 102 of the frame 100. The rotating brush 106 attached to the horizontal crossing part 105 of the upper part of the flame | frame 100 and the washing | cleaning liquid spraying apparatus not shown are comprised.

  In addition, in this specification, the same code | symbol written over each figure shows the same or similar member and thing.

  A pair of rotating brushes 104 and 104 are arranged with a cleaning piece around a vertical rotating shaft 110, and the cleaning piece moves while contacting the side surface of the vehicle body by the rotation of the rotating shaft 110, and the side surface of the vehicle body is cleaned. The

  The rotating brush 106 has a cleaning piece arranged around a horizontal rotating shaft 116, and the rotating piece 116 moves while contacting the upper surface of the vehicle body by the rotation of the rotating shaft 116, thereby cleaning the upper surface of the vehicle body.

  A plurality of cleaning pieces are arranged radially from the rotating shaft 110 (116). For example, as shown in FIG. 2, the crest 122 of the cleaning piece 112 that is folded in two with the surface to be in contact with the vehicle body positioned outside is disposed so as to be positioned on the outermost peripheral portion of the rotating brush 104 (106). Alternatively, there is also an aspect in which the cleaning piece is arranged in a pine umbrella shape with the rotating shaft 110 (116) as an axis.

  Examples of the rotating brush include a mode in which cleaning pieces are superposed and attached to the surface of the rotating disk, and a mode in which the cleaning pieces are mounted on the surface of a cylinder whose central portion in the longitudinal direction is reduced to a drum shape.

  The washing piece for a car wash machine of the present invention is attached to the car wash machine and functions as a car wash brush. As shown in FIG. 3, the washing piece 2 for a car wash machine of the present invention is provided with a raised layer 6 made of raised fibers 4 having a height h of 2 to 50 mm on the surface of a base material layer 3 having a fiber assembly solidified structure. , For car wash machines in which the constituent fibers constituting the base material layer 3 are joined by a joining mechanism selected from fusion of constituent fibers, fusion through a melted and solidified resin, and adhesion through an adhesive It is a cleaning piece.

  The base material layer 3 is a layer having a fiber assembly solidified structure. In the present invention, the fiber aggregate solidified structure refers to a structure in which aggregates composed of fibers that are arranged in part or in whole or are present at random from each other are solidified by adhesion or fusion.

  In the present invention, the base material layer 3 has a structure in which, for example, the fibers in the fiber assembly are bonded to each other with a water-resistant adhesive, or bonded together by fusion so that the fiber web is hardened.

In the fiber bonding rate in the present invention, the number of cross-sectional fibers of the constituent fibers in the cross section orthogonal to the surface direction of the base material layer 3 is Nt, of which, the constituent fibers are fused together, and are fused via a melted and solidified resin. Or when the number of constituent fibers bonded by a bonding mechanism selected from bonding through an adhesive is Nb,
It is a value defined by (Nb / Nt) × 100 (%).

  FIG. 4A shows the constituent fiber 10 in an area having a cross section perpendicular to the surface direction of the base material layer 3 when the fiber-to-fiber bonding mechanism is based on the fusion of the constituent fibers, and of these, the combined constituent fibers. 12 is shown.

  In FIG. 4B, when the bonding mechanism between the fibers is based on the bonding of the constituent fibers with the adhesive, the constituent fibers 10 in the area having a cross section perpendicular to the surface direction of the base material layer 3 are combined. The constituent fibers 12 and the adhesive 13 are shown. 4A and 4B, for the sake of clarity of explanation, the shape of the cross section of the fiber in the cross section orthogonal to the surface direction of the base material layer 3 is shown as a circle, but in reality, the fiber axis Depending on the orientation, the shape is elliptical.

  The fiber aggregate solidified structure in the present invention can be obtained by applying or impregnating an adhesive to the fiber aggregate constituting the base material layer 3 and then solidifying the adhesive by heating or the like. Alternatively, it can be obtained by fusing the fibers in the fiber assembly constituting the base material layer 3 together.

  The base material layer 3 having such a fiber assembly solidified structure has sufficient rigidity, and is excellent in dimensional stability with respect to the force received by the base material layer 3 during car washing. When the base material layer 3 does not have sufficient rigidity, when the brush rotates at a high speed, a trouble that the cleaning piece is turned up at the time of car washing due to insufficient rigidity is likely to occur. Further, the cleaning piece 2 may be stretched and deformed or damaged due to the force received by the base material layer 3 at the time of car washing, which is problematic in terms of durability.

  Moreover, since the base material layer 3 has sufficient rigidity, the impact force to the surface of the object to be cleaned due to the rotation of the rotating brush at the time of car washing increases, and the ability to knock off dirt is improved. A fiber bonding rate of 15% or more is preferable in terms of improving dimensional stability and cleaning ability by knocking off dirt. In order that the base material layer 3 has sufficient rigidity, it is more preferable that the fiber bonding rate of the base material layer 3 is 30% or more.

  The washing piece for a car wash machine of the present invention can be obtained by needle punching a web to form a pile, applying or impregnating an adhesive to the web opposite to the pile side, and then solidifying the adhesive.

  Alternatively, a web containing a heat-sealable fiber is needle punched to form a pile, and the web on the opposite side of the pile is heated to melt at least the surface of the heat-sealable fiber and fuse the fibers together. After cooling, it can be obtained by cooling the web.

  Furthermore, the web is layered on a non-woven fabric or a woven fabric, needle-punched from the web side to form a pile on the opposite side, and an adhesive is applied or impregnated on the web opposite to the pile side and then bonded. It can be obtained by solidifying the agent.

  Furthermore, a web made of non-woven fabric or woven fabric is overlaid with a web containing heat-sealable fibers, and a needle punch is formed from the web side to form a pile on the opposite side, and the web on the opposite side to the pile side is heated. Then, at least the surface of the heat-fusible fiber is melted and the fibers are fused together, and then the web is cooled.

  Furthermore, the web is overlapped with a base fabric made of a non-woven fabric or a woven fabric containing heat-fusible fibers, and a pile is formed on the opposite side by needle punching from the web side. The base fabric can be obtained by melting at least the surface of the fibers and fusing the fibers together and then cooling the base fabric.

  The fiber bonding rate can be controlled by adjusting the amount of heat-fusible fiber, heating temperature, and time contained in the web or base fabric, or by adjusting the amount of adhesive contained in the web. .

  Examples of the web for needle punching include a card web, a web by the air array method, and a spunbond (non-adhered or lightly bonded) web.

  The washing piece for a car wash machine according to the present invention includes a fabric (woven fabric or non-woven fabric) as a base fabric, and tufts a yarn on the base fabric using a tufting machine such as a tuft machine or a tuft sewing machine. It can be obtained by applying an adhesive to the root portion and then solidifying the adhesive.

  Furthermore, after using a tufting machine to tuft a yarn with a fabric containing heat-fusible fibers as a base fabric, the base fabric is heated to melt the heat-fusible fibers. Can be obtained by cooling.

  In the washing piece for a car wash machine of the present invention, if the height h of the raised hairs 4 exceeds 50 mm, the raised hairs 4 may be entangled during washing, and the tangled part may cause a trouble that is caught on a protruding part of the vehicle body such as an antenna. There is. In addition, water retention becomes excessive, and it is difficult to dehydrate after the car wash is finished, and the trouble that the washing piece freezes in the cold season is likely to occur. The height h of the raised hairs 4 is preferably 50 mm or less in order to prevent water retention from being excessive. It is further preferable that the water retention is 30 mm or less so that the water retention does not become excessive.

  When the height h of the napped hairs 4 is less than 2 mm, the water retention is lowered and the cleaning property is lowered. In addition, the cushioning property of the surface of the cleaning piece is deteriorated, and the vehicle body may be damaged during cleaning.

  As the fibers constituting the napped layer 6, polyolefin fibers such as rayon and polypropylene fibers, polyester fibers such as polyethylene terephthalate fibers, polyamide fibers such as nylon, acrylic fibers, synthetic fibers such as polyvinyl alcohol fibers, wool And natural fibers. The synthetic fiber may be a composite fiber composed of two or more kinds of resins. Two or more of these may be used in combination.

  The fineness of the fibers constituting the napped layer 6 is preferably 0.3 to 50 dtex. In addition, the cross-sectional shape of the fibers constituting the napped layer 6 is preferably a non-circular shape such as a substantially triangular shape, a substantially rhombus shape, or a semicircular shape in terms of detergency.

  At the time of car washing, the car wash machine cleaning piece 2 is rotated while water is supplied. The napped layer 6 rotates by washing with water by supplying water. The washing piece 2 for a car wash machine of the present invention is provided with a raised layer 6 composed of raised fibers 4 having a length of 2 mm or more, so that water is retained in the raised layer 6 at the time of car washing, and has an appropriate water retention property. Cleaning is performed effectively. If the washing piece retains excessive water, it will be in a state where a large amount of water is retained after the car wash is completed, so there is a problem that the washing piece is frozen in this state in the cold season such as winter, but the car wash machine of the present invention Since the cleaning piece 2 has a fiber assembly solidified structure in which the base material layer 3 is formed by hardening the fiber web, the base material layer 3 has little water retention, and the water held in the napped layer 6 is rotated after cleaning. Since the napped layer 6 is easily scattered by the rotation of the brush and dehydrated, there is little trouble that the cleaning piece is frozen.

  The washing piece 2 for a car wash machine of the present invention is arranged in the car wash machine so that the raised layer 6 is in contact with the washing surface of the object to be cleaned, and the object to be cleaned is cleaned by the raised layer 6. At this time, since the base material layer 3 does not directly hit the cleaning surface during cleaning, there is no possibility that the cleaning surface is damaged by the base material layer 3.

  Further, the car wash machine cleaning piece 2 according to the present invention is provided with the raised layer 6 having a height of 2 mm or more, so that the raised hairs 4 enter into the depressions in the minute uneven portions of the vehicle body during the car wash. There is little unwashed part. In addition, the presence of the raised layer 6 results in a cleaning piece having excellent cleaning water foaming properties, and improves the cleaning performance of the uneven portions on the surface details of the vehicle body.

  Further, the napped layer 6 is excellent in the ability to retain the dirt transferred from the vehicle body by the car wash, so that there is little possibility that the dirt transferred from the car body will transfer to the car body during the car wash and the car body will be recontaminated. When the base material layer 3 is mainly composed of a non-woven fabric, it is particularly excellent in the ability to keep dirt in this gap. Furthermore, the base material layer 3 has fine voids formed by gaps between the fibers, and has an ability to retain dirt in the voids.

  The dirt held in the napped layer 6 is held in a gap formed by the fiber group constituting the napped layer 6, and this gap is deformed by an external force caused by the rotation of the rotating brush and the like, and the fibers accompanying this deformation. As a result of this movement, the dirt held in the gap is likely to drop off, and the dirt once retained is easily scattered along with water by the rotation of the rotating brush. Therefore, the washing piece 2 for a car wash machine of the present invention is not easily soiled even when used for a long time.

  On the other hand, the cleaning piece made of the resin foam retains dirt in the void formed by foaming, but the dirt once retained remains in the void as it is, so that the dirt does not come off from the cleaning piece and accumulates, Immediately after use, dirt on the cleaning piece becomes noticeable.

  The raised layer 6 can also be formed by raising a nonwoven fabric with needles. The web can also be formed by needle punching in consideration of the needle arrangement and the hitting pitch. The web may be needle punched over the scrim. Alternatively, the napped layer 6 may be formed by tufting the yarn on the base fabric using a tufting machine. The raised layer 6 made of a cut pile can be formed using a tufting machine. A nonwoven fabric or a woven fabric is used as the base fabric.

  A non-woven fabric is a fabric in which fibers or aggregates of fibers are chemically, thermally, or mechanically bonded without being knitted.

  Examples of the nonwoven fabric used for the base fabric for tufting include wet nonwoven fabrics, dry nonwoven fabrics, spunbond nonwoven fabrics, and hydroentangled nonwoven fabrics.

  Examples of the base fabric for tufting include, but are not limited to, a jute fabric, a fabric using slit yarn, a composite sheet of a web and a fabric obtained by needle punching on a web using a slit yarn, and the like.

  The napped layer 6 may be a non-woven needle-raised or cut pile made of fibers with free ends (hereinafter, the napped group consisting of fibers with free ends including these is called cut pile). However, as shown in FIG. 5, a loop-like napped 20 (so-called loop pile) may be used.

The loop pile may be formed by punching the web with a fork needle, for example, by the method described in Japanese Patent Application Laid-Open No. 2000-119947.
Alternatively, as shown in FIG. 6, the loop pile 20a may be formed by tufting the yarn on the base fabric 14 using a tufting machine.

  When the napping is a pile obtained by needle punching or a pile obtained by raising, fraying of the fibers occurs in the napping layer 6 due to long-term use of the washing piece, and the fraying is a part of the vehicle body during washing. Even if it is caught, the caught fiber is short or is not in a state of being converged on the yarn, so even if it is pulled, it is easily cut or pulled out from the base material layer 3. Therefore, it is difficult to cause a trouble that the entire washing piece for the car wash machine is pulled during the car wash due to the catch.

  On the other hand, in the case of a pile in which the raised layer 6 is formed by knitting (knitting), the constituent fibers of the raised layer 6 and the constituent fibers of the base material layer 3 are continuous. Only the napped layer 6 does not fall off from the base material layer 3 when it gets caught in the body part, and the entire cleaning piece including the base material layer 3 is pulled, causing a trouble.

  When the napping is a loop pile, the ability to wipe the surface of the vehicle body and the ability to retain dirt transferred from the vehicle body are further improved.

  When loop piles and cut piles are mixed in napping, the ability to wipe the surface of the vehicle body and the ability to retain dirt transferred from the vehicle body is the best.

  For example, as shown in FIGS. 7 (a) and 7 (b), when the napped layer 6 is composed of a pile row in which the loop pile row 12 and the cut pile row 14 are alternately arranged in parallel, excellent soil retention by the loop pile, Excellent detergency is achieved by combining the ability to wipe off dirt with a cut pile.

Further, as shown in FIG. 7 (c), it becomes napped layer 6 from the pile rows were parallel loop pile rows 12 and cut pile row 14 alternately, and the pile height h _a of the cut pile row 14 loops further preferable in that is excellent cleaning properties which is higher than the pile height h _b of the pile rows 12a. In this case, _{h a} is _4~50mm, h a -h _b is preferably a 2 to 10 mm. h _a is 5 to 15 _mm, h a -h _b is more preferable in detergency it is excellent is 2 to 10 mm. It is preferable that h _a > h _b because the loop pile is not easily caught by the protrusion on the surface of the vehicle body even when the napped hair is a tufted loop pile.

Moreover, as the washing piece for a car wash machine of the present invention, when the napped layer 6 is made of a cut pile, the pile height is ² to 50 mm and the pile basis weight is 100 to 1500 g / m ^2. Can penetrate into the minute depressions of the vehicle body, so an extremely good cleaning property can be obtained. When the napped layer 6 is made of a cut pile, if the pile height is less than 2 mm, the pile fiber may not be able to enter the fine depression of the vehicle body. If the pile height exceeds 50 mm, the fibers constituting the pile may become tangled or entangled. If the pile basis weight is less than 500 g / m ² , the ability to wipe the body surface is insufficient. If the pile basis weight exceeds 1500 g / m ² , the pile is excessively spilled and the vehicle body is likely to be washed only with the upper surface of the pile, and the ability to wipe the vehicle body surface is insufficient.

  In the washing piece for a car wash machine of the present invention, when the napping is a loop pile by tufting, it is preferable that the pile height h is 6 mm or less because it is difficult to catch on the protrusion on the surface of the vehicle body.

  Natural fibers and recycled fibers can be used for the web for needle punching. Polyolefin fibers such as polypropylene fibers, polyester fibers such as polyethylene terephthalate fibers, polyamide fibers such as nylon, acrylic fibers Synthetic fibers such as fibers and polyvinyl alcohol fibers are preferred. Of these, hydrophobic synthetic fibers are preferred. The synthetic fiber may be a composite fiber composed of two or more kinds of resins. Two or more of these may be used in combination.

  The fibers used for the base fabric for tufting are polyolefin fibers such as rayon and polypropylene fibers, polyester fibers such as polyethylene terephthalate fibers, polyamide fibers such as nylon, acrylic fibers, and polyvinyl alcohol fibers. Natural fibers such as wool. The synthetic fiber may be a composite fiber composed of two or more kinds of resins. Two or more of these may be used in combination.

  As fibers used for yarns for tufting, synthetic fibers such as polyolefin fibers such as rayon and polypropylene fibers, polyester fibers such as polyethylene terephthalate fibers, polyamide fibers such as nylon, acrylic fibers, and polyvinyl alcohol fibers. Natural fibers such as wool. The synthetic fiber may be a composite fiber composed of two or more kinds of resins. Two or more of these may be used in combination. The yarn for tufting may be a spun yarn. It may be a multifilament. The tufting yarn may contain heat-fusible fibers.

  Examples of the yarn for tufting include spun yarn, multifilament yarn, processed yarn, and composite yarn of spun yarn and multifilament yarn or processed yarn.

  The yarn for tufting may be a strong twisted yarn. When a loop pile is tufted using a strong twisted yarn, a pile having a twisted structure is obtained due to twist caused by twisting torque. A pile having such a twisted structure has good convergence, so that the ability to knock off dirt is improved. Further, since the dirt penetrates into the narrow dent of the vehicle body in units of yarn and the dirt in the dent portion is scraped out in units of yarn, the dirt scavenging effect is superior to that in the case of scraping out dirt in units of fibers. Furthermore, since the yarns are converged due to the warp, there is almost no possibility of catching on the protrusions even if the pile loop height is 6 mm or more.

  A strongly twisted yarn refers to a yarn having a twist coefficient K represented by K = T / √N of 150 or more when the yarn count is N (m / g: metric count) and the number of twists is T turns / m. The twist coefficient K of the strong twisted yarn in the present invention is preferably 150 to 200.

  The heat-fusible fiber used in the present invention is a fiber in which at least a part of its surface is melted by heat. The heat-fusible fiber may be one in which the entire fiber melts at a predetermined temperature, but consists of a sheath part made of a resin having a relatively low melting point and a core part made of a resin having a melting point higher than that of the sheath part. Core-sheath fibers are preferred. The core-sheath fiber can melt only the sheath part at a predetermined temperature.

  It is preferable that the heat-fusible fiber is mixed with a fiber made of a resin having a melting point higher than that of the fusing component resin and used as a web, a nonwoven fabric or a woven fabric.

  Examples of the adhesive used for forming the base material layer 3 include natural rubber-based, olefin-based, urethane-based, acrylic-based, and epoxy-based emulsion adhesives. It may be a solvent type or a melt type such as a hot melt adhesive. This adhesive preferably has water resistance, weather resistance and detergent resistance. These adhesives are preferably those that are crosslinked by curing. The adhesive is applied to the fiber assembly layer constituting the base material layer 3 by, for example, a coating method or a spray method. The adhesive may be applied in a planar shape. Alternatively, it may be given in the form of dots.
