DETAILED DESCRIPTION OF THE INVENTION The present invention has been made to solve the above-mentioned problems, namely,
We carefully studied the anti-slip tape that is easy to wind around the grip part and is less slippery even when used in a wet state, and has excellent touch, fit and durability, and polyparaphenylene is applied to the rubber surface of the rubberized tape. When a tape made by electro-flocking a specific fiber called terephthalamide fiber as a pile yarn was prepared, the cut elongation of the tape was 30% or more, and the adhesive wear strength of the flocked pile was 10%.
It has been found that it is possible to provide a function having at least 00 functions, that is, one that can solve the above-mentioned problem at once.

[0010] In the present invention, as the cloth-like material, a woven fabric using synthetic fibers typified by polyamide, polyester, or the like, or natural fibers such as cotton or hemp; a knitted fabric such as a vertical knit or a horizontal knit; Use non-woven fabric composed by entanglement or bonding fibers with an adhesive, or natural leather such as cow or deer, or synthetic leather obtained by coating or laminating non-woven fabric with resin or laminating Can be.

The fiber material used for such a cloth material may be a single material or a combination of two or more materials. It is important that these fabrics have an elongation of 30% or more. In other words, when the tape having a large elongation is wound around the grip portion when it is wound under tension, it is easy to wind along the shape of the grip portion serving as a base, and it is difficult to loosen, so that the tape is firmly fixed. be able to. However, the elongation is 30%
If the material is smaller, a large tension is required at the time of winding, and even after the winding, the material tends to be displaced or deformed and loosened. On the other hand, if the elongation of the cloth is too large, the tightening after winding and the difficulty in slipping are excellent, but the winding work is difficult, so the elongation of the cloth is as follows. Preferably at most 200% or less, more preferably 3% or less.
About 0 to 100% is good.

In order to impart elongation to the cloth-like material, the elongation of the fibrous material used is large, or when the elongation of the fibrous material is small, the fabric structure, that is, the vertical bending Means such as weaving with a woven structure of the structure, or a woven fabric with low elongation may be used by being cut in the bias direction. Further, a fabric made of a high shrinkage yarn may be shrunk in a dyeing step or a dry heat treatment. Further, in the case of a knitted fabric such as a vertical stitch or a weft stitch, the elongation generated from the structure is large, so that it is more preferably used.

The fibers constituting the tape made of such a cloth-like material may be filament yarns or staple yarns, but from the viewpoint of the effect of being easily adhered to rubber in a later step and of the adhered rubber being difficult to peel off. Preferably, a staple yarn, a spun-like filament yarn in which a filament yarn is entangled with an air or the like, or a yarn using a fluff yarn in which the filament yarn is further rubbed are used. Fabrics and knits using these filaments are preferable because of their high strength.

In the present invention, a polyparaphenylene terephthalamide fiber (hereinafter referred to as a para-aramid fiber) is defined as having a tensile strength of 20 g / d or more and a grease of 500 g / d.
It is a fiber having the above initial tensile resistance (Young's modulus) and excellent in heat resistance, chemical resistance, and the like. The fiber is more rigid than ordinary synthetic fibers such as polyamide and polyester.
The present inventors have determined that such para-aramid fibers exhibit a special function of being extremely non-slip after flocking.

The pile thread for flocking is obtained by cutting para-aramid fibers with a guillotine cutter or the like. Such a pile yarn preferably has a single yarn fineness of 0.5.
A pile yarn having an aspect ratio of preferably 20 to 100 is used. That is, the aspect ratio indicating the relationship between the single-fiber fineness and the pile length is a factor that affects the feel of the palm and fingertips when gripping the grip, particularly the hardness, buckling feeling, settling, wear strength, and the like. Things. Such a para-aramid fiber has a high tensile resistance (Young's modulus) and is hard to cut the pile length because the yarn is hard. Therefore, the lower limit is 0.3 mm. The pile length is preferably 0.5 mm or more. However, if the pile length is too large, a buckling sensation occurs when the user grips the grip. Para-aramid fibers are more difficult to spin than polyamide fibers and polyester fibers, cannot increase or decrease the single-fiber fineness extremely, and are preferably manufactured from the viewpoint of ease of production. The thickness is in the range of about 0.5 denier to about 10 denier. Therefore, from these, the aspect ratio of the pile yarn is preferably 20 to 100, and more preferably 30 to 60.

Further, similarly to the aspect ratio described above, the flocking density of the pile yarn affects the feel of the palm and the fingertip when the grip is gripped and the peelability between the pile yarn and the base material. If the density is too low, it tends to slip and peel easily. Also, if the flocking density is too large, it gives a feeling that is too hard, so from these points,
The flocking density, preferably 3 to 10 million units / cm ^2, further preferably from those having 5 to 7 million units / cm ^2.

The anti-slip tape of the present invention uses a rubberized fabric made by applying rubber on the fabric, and the rubber may be either synthetic rubber or natural rubber. Can be. However, from the viewpoint of adhesiveness, synthetic rubbers, among which nitrile rubber and butyl rubber, are most preferably used. Such nitrile rubber or butyl rubber may be used alone, or may be a mixture of nitrile rubber and butyl rubber. Further, as long as the rubber contains at least 50% by weight of nitrile rubber or butyl rubber, it may be used in combination with another rubber. In addition, additives such as pigments, weathering agents, and cross-linking agents may be added to the rubber to further improve processability and characteristics.

These rubbers are applied to at least one surface of a fabric in the form of a solution dissolved in a solvent such as toluene or benzene to form a rubber layer or to be dispersed in a liquid together with a dispersant. The processed rubber may be processed into a fabric and then heated to crosslink. If the rubber layer is too thick, the tape after processing becomes hard, and the workability at the time of winding around the grip deteriorates. The thickness of such a rubber layer is preferably 10
Those having a size of 00 microns or less are preferred.

The rubber layer formed on one side of the cloth-like material is coated with an ethyl acetate-based pretreatment agent and then bonded with a urethane-based adhesive as a step before bonding to the pile yarn. This is preferable because the adhesive strength between the rubber and the pile yarn is increased. The urethane-based adhesive may also contain additives such as an adhesive agent, a weather resistance improver, and a viscosity modifier, and if the urethane-based adhesive is contained at 50% by weight or more, it may be combined with another adhesive having good compatibility. It may be used in combination. The amount of the adhesive applied is preferably about 100 g in solid content. The method of electric flocking may be any commonly used up method, down method, etc., and is not particularly limited.

The anti-slip tape of the present invention thus obtained is characterized in that it has an adhesive abrasion strength of at least 1,000 times, preferably at least 1500 times, and more preferably at least 2,000 times, as described above, and has high adhesiveness. Having. The adhesive abrasion strength is determined by the number of times of friction until the pile is peeled off when a cotton cloth with a constant load is rubbed against the pile surface electro-flocked on the tape surface as described in Examples described later. It is shown by the evaluated value. The adhesive wear strength is affected by factors such as the type of adhesive, the aspect ratio of the pile, the presence or absence of pretreatment, and the density of flocking.

Further, the anti-slip tape of the present invention comprises:
The following slip resistance is preferably 3.0 kg or more when wet,
More preferably, an excellent anti-slip effect of 3.5 kg or more is exhibited. Here, the slip resistance value (kg) is measured using a constant-speed tensile tester as specified in Examples described later, and the resistance value when the flocking pile surface of the tape is rubbed with a specific cloth. Is recorded on a chart, and the average value is read and obtained.
