Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an electrostatic flocking material for friction prevention, and particularly to a material technology for enhancing grip performance of golf clubs and the like.

[0002]

[Prior art]

 The gripping grips of tools such as golf clubs and tennis rackets, as well as tools such as hammers, need to be non-slip due to sweat and oil during use. Hereinafter, the explanation will be given by using the golf club which has the most severe usage conditions. This is because golf clubs can have very different score results even with slight slippage. Although the present invention can be applied to tools such as a hammer, it does not have the strictness required for golf clubs. For sports equipment grips and tools other than golf clubs, less slippage is desirable for ease of use and reduction of tiredness, but of course the application of the present invention is not hindered.

Conventionally, as a non-slip technique applied to a grip of a golf club, a cover material made of rubber or synthetic resin arranged on a grip grip is provided with a large number of irregularities (Japanese Patent Laid-Open No. 6-205861). issue). The large number of minute irregularities increase the coefficient of friction and enhance the anti-slip effect especially in rainy weather. There is also a technique of knitting a fiber material and arranging it in the grip (Japanese Patent Laid-Open No. 6-57601). This is a loop stitch made of polyurethane elastic yarn to provide a highly stretchable anti-slip member.

However, in the method in which the rubber cover material of the grip is provided with unevenness, if the grip gets wet by raindrops or sweat, even if there is unevenness, it becomes slippery, and further, it becomes difficult to make an ideal swing because of stickiness. For this reason, glove is generally used because it is difficult to hold the grip with bare hands. However, it goes without saying that the bare hands that do not use gloves have a better grip feeling.

Therefore, the present inventor has proposed an electrostatic flocking technique using elastic rubber for the substrate in order to improve the feel when gripping the grip and surely prevent slipping due to rain or sweat. No. 7-39304). Since the base sheet is made of rubber, the touch is soft, and the electrostatically-implanted pile (fine fibers) makes point contact with the palm of the hand, resulting in a significant improvement in the coefficient of friction.

However, since a harsh external force is applied to the golf grip, there is room for improvement, such as the flocked pile falling off after a few thousand shots have been repeated.

[0007]

[Problems to be solved by the device]

 Therefore, as the simplest improvement measure, it was attempted to spray the surface with a coating agent to prevent peeling and falling of the flock pile.

In fact, according to this method, the hair loss probability of the hair transplant pile can be reliably prevented. However, the grip feels too soft when touched by hand, and the slippery feel increases.

As a result of examining the reason, the following has been found. That is, as shown in FIG. 10, when the coating material is sprayed from the surface, the coating material does not reach the inside of the pile, and the rounded coating material 2 is solidified and remains at the tip of the flocked pile 1. Therefore, the roundness of the resin remaining at the tip gives a slippery feel.

Moreover, it was also found that the coating agent 2 sprayed by spray does not reach the rubber substrate 3 on which the flocked pile 1 is planted sufficiently. This is because the pile 1 is a fine fiber having a denier of 10 to 30 and is densely planted with hair, so that the coating agent particles cannot enter the minute voids 4 between the fibers. As a result, the base end of the pile 1 remained unchanged even after spray coating, and no favorable result was obtained in preventing hair loss. It should be noted that if the spray is brought close to the flocked surface and it is forcibly sprayed, the resin can be coated even on the base portion, but if this is done, the resin will be impregnated and solidified from the tip surface of the pile, and the meaning of flocking will be lost.

Therefore, the present invention has an object to secure friction performance while using a coating agent for preventing hair loss of a pile.

[0012]

[Means for Solving the Problems]

 To achieve the above object, the present invention has the following configurations. The fiber tip portion of the electrostatic flocking pile is covered with a hard resin whose outer peripheral surface has a corner portion (outer edge shape without roundness). More specifically, the electrostatic flocking material in this case is made by using an elastic resin to apply an adhesive to the surface of the base material to perform electrostatic flocking, and then immersing the base material in the surface coating agent solution. After that, it is lifted up and the coating agent adhering to the surface is brushed to make the coating thickness of the coating agent uniform, and then the coating agent is wiped off with a water-absorbent material. The electrostatic flocking material formed in this way is cut to an appropriate size, or is preformed into a tape shape and attached to the grip, or electrostatic flocking is applied to a preformed rubber material according to the grip shape. Apply it to exercise equipment.

[0013]

[Action]

 In the electrostatic flocking material according to the present invention, the fiber tips of the electrostatic flocking pile are covered with a hard resin having an angular outer peripheral surface. The tip of the pile is covered with a hard resin that has a sharp angle, so that the material feels rough when touched by hand. The hard resin that coats the pile tip is a coating agent, and since it has its original roundness removed, there is no danger of damaging the skin.

Specifically, the electrostatic flocking material is configured as follows. The frictional property of the electrostatic flocking material according to the present invention occurs only when the coating agent applied to the pile surface is rounded to have an angle. By dipping the flocking material in the coating agent solution, the coating solution enters the microvoids between the flocking piles, but this alone cannot make the coating agent have an angle. By uniformizing the wall thickness of the coating agent attached to the tip of the pile by brushing, the gap between the piles is uniformly filled with the coating agent. Even if the solution is absorbed without going through this process, extraneous resin remains at the pile tips due to the unevenness of the adhesive, and it is not possible to leave a coating resin with clean squareness. On the other hand, when the surface coating is evenly arranged and the water-absorbent fabric is applied to absorb the solution, the coating agent remaining at the tip of the pile does not have roundness but appears as a well-balanced and angular shape. . It is considered that this is because when the surface resin is absorbed, the corner portion is formed by leaving the resin that cannot be completely sucked at the tip of the pile.

It is most desirable that such an electrostatic flocking technique is applied to exercise equipment, particularly to a grip portion where a sliding condition such as golf or tennis is severely reflected in the result. Even if you do not wear gloves in the rain, you can get a quality characteristic different from the conventional exercise equipment grip if you have a grip that does not slip at all when you apply force and the feel in your hand is soft. Because.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an example of a molding sequence of the electrostatic flocking material according to the present invention. In this example, the reference numerals were changed as necessary to clarify the remaining portion of the coating agent.

First, an electrostatic flocked fabric to which the present invention is applied is made (S-1). Unlike the usual electrostatic flocking material that is usually found, this material is based on elastic resin such as rubber, and electrostatic flocking is applied to it. Since elastic hair is normally applied to a stretchable cloth such as a rubber mat to cause hair loss due to the expansion and contraction of the cloth, the present inventor has proposed a means for solving the above problem (Japanese Patent Application No. 7- 39304). Since the technology of this part is not directly related to the subject of the present invention, it will be separately described in the last stage.

Next, the cloth on which electrostatic flocking is applied is dried to fix the adhesive, and then washed with water (S-2). This is to remove excess pile and dust.

Next, the entire dough is dipped in a coating agent (S-3). This is because the resin solution is sufficiently applied to the entire pile surface. Incidentally, as the coating agent, for example, an adhesive for vinyl chloride, especially a urethane resin is desirable.

Then, the dough is immediately pulled out of the solution, and the entire pile surface is squeezed by hand (S-4). As a result, as shown in FIG. 2, the coating material 12 enters the gap between the piles 10.

Next, brushing is applied to the pile surface (S-5). As a result, as shown in FIG. 3, the thickness of the coating agent 15 remaining on the pile surface is evened out. This treatment is extremely important. For example, if there is unevenness 16 of the coating material on the pile surface as shown in FIG. 2, the resin will not remain in the shape of a corner at the end of the pile 10 (see FIG. 2b). State).

After the brushing, the surface of the cloth is wiped off with a water absorbent material such as cloth towel (S-6). As a result, as shown in FIG. 4, the coating agent that has entered the gap between the piles 10 is sucked up, and the coating agents 17 and 18 are left behind at the base end portion and the tip end portion of the pile 10, respectively. The shape of the resin 18 at the tip of the pile conceptually has a large number of squares as shown in (b), and this shape can be visually confirmed using a magnifying glass. It should be noted that when wiping the substantially cylindrical cloth 31 as shown in FIG. 5, it is possible to obtain good results by wiping it so that it rolls on the towel 32. In that case, it is efficient to use a semi-cylindrical device 70 having a handle 71.

The resin 17 remaining at the base end portion prevents the hair loss by pressing the root of the pile 10 and also remains only at the root so that the free movement of the pile 10 is not restricted. On the other hand, the resin 18 remaining on the tip remains as a shape with corners when the solvent is sucked up by the towel. The shape and angle of the corners are not always constant, but they do not remain as rounded shapes.

By the above processing, the resin 18 having an angle can be left at the tip of the pile, which is the object of the present invention. Then, the dough is dried to solidify the resins 17 and 18 to obtain a finished product (S-7, S-8). After the surface is wiped off, a coating spray may be applied to the pile surface if necessary (S-9). This spray processing will be described later.

Through the steps described above, the resin 18 having corners remains and solidifies at the tip of the pile 10 as shown in FIG. Therefore, when the dough 20 is appropriately cut and placed on the grip of exercise equipment or tools, the following effects are obtained. The electrostatic flocking material that the inventor previously proposed does not slip even if the grip gets wet with rain or sweat, but prevents slipping by increasing the pile density, but leaves a resin 18 with corners at the tip of the pile Even if the pile density is reduced to some extent, a high anti-slip effect is obtained. The pile 10 does not fall off even after repeated violent swings The resin 17 remains at the base end of the pile 10, so the root of the pile 10 remains firmly fixed even if the tip of the pile moves back and forth and left and right due to a violent swing. It is because. Fall prevention of piles For the same reason, the piles 10 are prevented from falling and the slip-prevention effect can be guaranteed for a long time. If the root of the pile is not firmly fixed, the pile will lie down and become slippery, but the resin 17 at the base end keeps the pile 10 upright for a long time.

In addition, in the above-mentioned example, after dipping in the solvent, it was squeezed by hand (S-4). This process is to make the adhesive enter into the gap between the piles, but the means for accommodating the solvent to the pile is not limited to this. For example, brushing is performed in the next step (S-5), but if the conditions such as the grounding pressure of brushing, the moving (rotating) speed, and the fiber thickness of the brush used match the flocking density of the pile 10, etc. You can apply only by yourself. Immediately after dipping, brushing can be performed to simultaneously apply the ink and the smoothing process. Further, in order to adapt the solvent to the pile, it is possible to substitute it by a pressing means such as a rotating roller. FIG. 7 shows a step in which the step (S-4) is omitted, and FIG. 8 shows a step (S-4b) in which the rotating roller is used. According to these processing methods, it is possible to automatically process a series of processes.

Further, after the solvent on the surface is wiped off, the coating agent may be sprayed (S-9). This is because when the spray is applied at the final stage, a rounded resin 19 is attached and formed on the tips of some of the piles as shown in FIG. 6, and it is possible to soften the feel when touched by hand. . In this case, it is sufficient that the spray resin is applied in a trace amount of a softer resin than the coating resin applied first. The final application of a small amount of spray can further expand the applications such as grips used by people with weak skin and grips that require a delicate touch.

The pile to be used is not particularly limited, but it is desirable to use a pile having a fiber cross-sectional diameter of 10 to 30 denier and a fiber length of 0.3 to 0.8 mm. If chemical powder is used in the form of a mixture with flocked pile, lame will appear dispersed on the entire surface of the soil. By scattering gold and silver glitter, dust and dirt, and dirt caused by sweat and oil can be made inconspicuous.

Finally, a method for producing an electrostatic flocking cloth for applying the present invention described in step (S-1) will be described (see FIG. 9). First, the surface of the cover material 3 is polished with the rotating brush 52 to increase the adhesive area of the adhesive (a). The rotating brush 52 uses, for example, an iron wire brush. Next, a primer is applied to the surface of the polished cover material 3. Next, an adhesive is applied to the surface of the cover material 3 (b). Reference numeral 54 is an adhesive ejection nozzle. The adhesive used here is an adhesive that can follow the expansion of the elastic resin in consideration of expansion when the cover material 3 is fitted to the grip. For example, polyester type urethane resin emulsion and the like.

Next, while the cover material 3 is rotated in the electric field, the pile 10 is planted on the surface (c). Reference numeral 56 is a case containing short fibers (pile) as a material, 57 is a vibrator for vibrating the case 56, and 58 is a net for evenly dropping the pile 10. This method is a so-called down type. Normally, the up / down type in which the pile 10 is planted from the upper and lower sides is preferable, but if the weight per pile is large, it is difficult to form a uniform pile density in the electric field, and thus such a down type is preferable. It should be noted that a vibrator is not necessarily used as a means for making the density of the piles dispersed in the electric field uniform, and for example, a pinch roller-shaped feeding device is used to make the pile density evenly distributed. Is also good. The material of the pile 10 is not particularly limited. For example, nylon, polyester, acrylic, polyurethane and the like.

If the pile is too short, a rough feeling is produced, and if the pile is too long, the hand is shaken due to the bending of the short fibers. The pile 10 applied to the present invention has a fiber cross-sectional diameter of 10 to 30 denier and a fiber length of about 0.3 to 0.8 mm. After the flocking of the cover material 3 is completed, the cover material 3 is dried by the heater device 60 (d), cooled by the cool air from the nozzle 61 (e), and brushed in the water tank 62 to be bonded. The remaining pile that was not present is removed (f). By the above, an electrostatic flocked fabric to which the present invention is applied is obtained (g). Then, the fabric obtained in this manner is subjected to the processing from (S-2) shown in FIG.

[0032]

[Effect of the invention]

 As described above, according to the electrostatic flocking material according to the present invention, since the resin is solidified at the base end of the pile, hair loss can be surely suppressed, and at the end of the pile, a resin having an angle is formed. As a result, the anti-slip effect can be enhanced.
