Description

  The present invention relates to a grip tape, and more particularly to a grip tape used by being wound around a grip portion of a bicycle handle, a tennis racket, a golf club, a baseball bat, a fishing rod, various tools, or the like.

  As shown in FIG. 4, the grips 10 of bicycle handles, tennis rackets, golf clubs, baseball bats, fishing rods and various tools are gripped to prevent them from slipping in the hand when they are held. The tape 51 is wound spirally. As such a grip tape, for example, as disclosed in Patent Document 1 and Patent Document 2 below, a non-slip layer such as a urethane layer or a rubber layer is formed on the surface of a strip-shaped nonwoven fabric, and the back surface thereof. There are known those having a form in which a pressure-sensitive adhesive layer and an adhesive layer are formed. The anti-slip layer may be provided with irregularities in order to give a grip effect. As shown in FIG. 4, the grip tape 51 is wound and bonded to the target area of the grip portion 10 so as to partially overlap. At the time of bonding, the grip tape is stretched in the longitudinal direction and wound while being applied with tension so that the bonded grip tape does not turn or shift during use.

  Such a grip tape is likely to be worn by use or dirty due to sweat absorption. For this purpose, the old grip tape is peeled off, and a new grip tape is rewound and re-worn.

Japanese Patent Laid-Open No. 11-18909 JP 2009-28250 A

  When the grip tape is wound around the grip portion, the grip tape is usually stretched while tension is applied. In the case of the conventional grip tape, for example, when tension is applied in the longitudinal direction L to the grip tape 51 having a shape as shown in FIG. 5A, as shown in FIG. In some cases, the width may shrink in the width direction W perpendicular to the longitudinal direction L. In the operation of winding the grip tape around the grip portion, there is also a demand for winding without gap so as to overlap as much as possible as shown in FIG. However, it is difficult to maintain almost the same tension from the beginning to the end of winding in the longitudinal direction. As shown in FIG. 6, the dimension in the width direction changes more than expected due to the change in tension. In addition, the width of the overlapping portion may be non-uniform or a non-overlapping portion N may be formed.

  An object of the present invention is to solve the above-described problem, that is, to provide a grip tape that can suppress a decrease in dimension in the width direction due to a tension applied in a longitudinal direction.

  The present invention is a grip tape that is wound around and fixed to a grip part to be gripped by an article, and a non-woven fabric cut into a strip shape having a longitudinal direction and a width direction perpendicular to the longitudinal direction. The non-woven fabric is a grip tape containing long fibers and a binder resin that binds the fibers. Thus, by using a nonwoven fabric containing long fiber as a nonwoven fabric, tension is applied in the longitudinal direction as compared with the case of using a nonwoven fabric made of short fiber used as a base material of a conventional grip tape. A grip tape is obtained in which a reduction in the dimension in the width direction when hung is suppressed. In addition, since the grip tape of the present invention uses a nonwoven fabric containing long fibers, when the grip tape is worn out, the fibers are difficult to come off and fray, and the end face is often observed on a used grip tape. There is also an effect that the occurrence of fiber fraying is also suppressed. Furthermore, when manufacturing the grip tape of the present invention, when the base material is cut out from the nonwoven fabric raw sheet in a strip shape, the nonwoven fabric made of short fibers is used because the nonwoven fabric has a long fiber length. The occurrence of fiber facets that often occur when cutting the anti-sheet is also suppressed.

  In the grip tape, the degree of orientation of the fibers in the nonwoven fabric is preferably higher in the longitudinal direction than in the width direction. In such a case, it is possible to obtain a grip tape in which contraction of the dimension in the width direction is particularly suppressed when tension is applied in the longitudinal direction. In a normal nonwoven fabric manufacturing process, since the nonwoven fabric raw sheet is manufactured while being pulled in one direction, tension is applied in the direction of pulling during manufacturing. Therefore, the degree of orientation of the fiber increases in the take-up direction.

  Moreover, it is preferable that a nonwoven fabric contains the ultra-thin fiber which is 1-5 micrometers in diameter. Thus, when the nonwoven fabric contains very fine fibers, since the fiber density can be made dense, shrinkage in the width direction can be further suppressed, wear resistance is also improved, and the surface is further improved. It is also preferable from the viewpoint of rapidly absorbing and diffusing moisture such as sweat adhering to the surface.

  Moreover, it is preferable from the point which is excellent in the design property while being excellent in abrasion resistance that the fiber which becomes the surface side exposed when wound is heat-sealed.

  Moreover, it is preferable from the point which grip property improves that the surface layer which consists of a polymeric elastic body is further laminated | stacked on the surface side wound and exposed.

  Such a grip tape is usually used with an adhesive layer or an adhesive layer laminated on the back side. And it adheres to a grip part by such an adhesion layer or an adhesive layer.

  According to the grip tape of the present invention, when wound around the grip portion, the reduction in the dimension in the width direction that is likely to occur when being wound while being pulled in the longitudinal direction is suppressed. Therefore, the grip tape of the present invention is excellent in workability when wound and bonded.

  An embodiment of the grip tape of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view showing a cross section of a layer of a grip tape 1 and a partially enlarged view of a grip tape substrate 2 according to an embodiment of the present invention. In FIG. 1, 2 is a grip tape substrate, 3 is an adhesive layer formed on the back surface of the grip tape substrate 2, and 4 is a release paper that protects the adhesive layer 3. Moreover, the area | region enclosed by blowing shows the enlarged schematic diagram which shows a mode that the long fiber 2a which forms the grip tape base material 2 is bound by the binder resin 2b.

  The grip tape base material 2 uses a non-woven fabric cut into a strip shape or a tape shape having a longitudinal direction L and a width direction W orthogonal to the longitudinal direction L as a base material, and the non-woven fabric suppresses a tangled deviation from the long fibers 2a. In order to do so, a binder resin 2b for binding the long fibers 2a is included.

  The kind of fiber which forms the long fiber 2a is not particularly limited. Specific examples thereof include, for example, polyester resins such as polyethylene terephthalate (PET), polytrimethylene terephthalate, polybutylene terephthalate, and polyester elastomer; polyamides such as polyamide 6, polyamide 66, polyamide 610, aromatic polyamide, and polyamide elastomer. Resins; acrylic resins; olefin resins such as polyethylene and polypropylene; and fibers formed from synthetic resins such as polyvinyl alcohol resins. These may be used alone or in combination of two or more. In these, the fiber formed from the polyester-type resin and the polyamide-type resin is preferable from the point which is excellent in abrasion resistance and mechanical strength.

  The long fibers are produced by a method for producing long fibers such that, for example, spun long fibers spun by a spunbond method are deposited on a collection surface such as a movable net. In addition, a long fiber is a fiber which has the fiber length which is longer than the short fiber whose fiber length is about 3-80 mm normally before the entanglement process mentioned later is not cut | disconnected intentionally. For example, the fiber length of the long fiber is preferably 100 mm or more, and can be several m, several hundreds m, several km or more unless it can be technically manufactured and physically cut. May be. In addition, although the nonwoven fabric of this embodiment mainly contains a long fiber as mentioned above, it may also contain a short fiber in the range which does not impair the effect of this invention.

  The form of the long fiber is not particularly limited and is appropriately selected depending on the application. Specific examples thereof include solid fibers, hollow fibers, and modified cross-section fibers. Further, the fineness of the long fibers is not particularly limited, and examples thereof include fibers having a general fineness with a diameter of about 10 to 30 μm, and ultrafine fibers with a diameter of about 0.5 to 10 μm, and further about 1 to 5 μm. It is done. Among these, ultrafine fibers are preferable, and in particular, in the case of a fiber bundle-like ultrafine fiber in which a plurality of ultrafine fibers are bundled to form a fiber bundle, the fiber density can be made dense. In addition, it is possible to further suppress the reduction of the dimension in the width direction, to impart excellent wear resistance, and to rapidly absorb and diffuse moisture such as sweat adhering to the surface of the grip tape. This is preferable because of its high effect.

  Moreover, the nonwoven fabric contains the binder resin 2b in the inside for the purpose of improving form stability by binding long fibers 2a and suppressing the shift | offset | difference of an entanglement state. The type of the binder resin is not particularly limited, but specific examples include resins and elastomers such as polyurethane, acrylic resin, polyethylene, polyolefin, petroleum resin, asphalt, isoprene hydrocarbon, butadiene rubber, and vinyl chloride. .

  The binder resin is preferably present so as not to block the internal voids of the nonwoven fabric. When the internal voids of the nonwoven fabric are closed, the function of absorbing and transmitting sweat or the like is lowered, so that grip properties during use tend to be lowered.

  The ratio of the mass of the binder resin to the mass of long fibers is preferably 0.01 to 50 mass%, more preferably 0.05 to 30 mass%, and particularly preferably 0.5 to 20 mass%. When the ratio of the binder resin is too high, the function of absorbing or transmitting sweat or the like is reduced, and when the ratio of the binder resin is too low, the binding force on the fiber is weakened and the shape stability is reduced. There is.

The apparent density of the non-woven fabric is not particularly limited. For example, in the case of a non-woven fabric made of ultrafine fibers, 0.05 to 1.2 g / cm ³ , further 0.08 to 0.7 g / cm ³ , especially 0.3-0.7 g / cm ³ is excellent in form stability due to the dense fibers, and also has the effect of rapidly absorbing and diffusing moisture such as sweat adhering to the surface of the grip tape. It is preferable because it is high and wear resistance is also improved.

  Also, the thickness of the nonwoven fabric is not particularly limited, but is preferably about 0.3 to 2 mm, more preferably about 0.5 to 1.5 mm from the viewpoint of excellent balance between form stability and mechanical strength. .

  An adhesive layer or an adhesive layer (adhesive layer 3) for fixing to the grip portion is formed on the back surface of the grip tape substrate 2 of the grip tape 1, and the adhesive layer 3 is wound around the grip portion. It is protected by a release paper 4 that is peeled off before being used. The pressure-sensitive adhesive layer 3 is not particularly limited as long as it is a pressure-sensitive pressure-sensitive adhesive or adhesive that has been conventionally used as a pressure-sensitive adhesive or adhesive for grip tapes. Adhesives and rubber adhesives.

  Such a grip tape 1 has a belt-like or tape-like shape and is usually wound and traded. Although the width | variety of the grip tape base material 2 is suitably selected according to a use, it is 10-30 mm normally, Furthermore, it is about 20-30 mm. The grip tape 1 of this embodiment is used by being wound around a grip portion of a bicycle handle, a tennis racket, a badminton racket, a golf club, a baseball bat, a hockey stick, a fishing rod, various tools, or the like.

  In addition, the surface of the nonwoven fabric on the side exposed when wound on the grip may be further post-treated. Specifically, for example, as shown in FIG. 2, the surface of the nonwoven fabric on the side exposed when wound on the grip is hot-pressed to heat-bond the long fibers 2 a existing on the surface. A grip tape 11 having a so-called fiber silver surface in which a fused portion M is formed, or a polymer elastic body on a surface exposed when wound on a grip as shown in FIG. It may be a form like the grip tape 21 in which the surface layer 5 is further laminated.

  In addition, it has the fiber silver surface which fuse | melted the long fibers 2a which exist in the surface by heat-pressing the surface of the nonwoven fabric of the side exposed when wound on a grip as shown in FIG. In the case, it is preferable from the viewpoint of improving the design and wear resistance. In this case, not all of the long fibers 2a are completely melted into a plate shape, but absorbs moisture such as sweat, and the surface has voids so that the absorbed moisture can be diffused and diffused. Is preferably left behind.

  Moreover, when the surface layer 5 which consists of a polymeric elastic body is further laminated | stacked on the surface of the side exposed when it winds around the grip of a nonwoven fabric as shown in FIG. 3, it is preferable from the point which grip property improves. . Specific examples of the polymer elastic body are preferably polymer elastic bodies such as urethane resins, acrylic resins, and various elastomers, and particularly porous polymer elastic bodies having a cell structure. Further, the surface layer 5 may be provided with a dot-like, stripe-like, or mesh-like recess or through-hole in order to improve the anti-slip property.

  Next, as a representative example of the method for manufacturing a grip tape of the present invention, an example of a method for manufacturing a grip tape containing a nonwoven fabric formed from a bundle of ultrafine fibers, which is a particularly preferable form of the grip tape, will be described in detail.

  In this production method, first, a fiber web is produced by melt spinning an ultrafine fiber generating fiber such as a sea-island fiber using a mixed spinning method or a composite spinning method.

  In addition, in this embodiment, although the case where a sea island type fiber is used as an ultra fine fiber generation type fiber is explained in detail, even if an ultra fine fiber generation type fiber other than a sea island type fiber is used, an ultra fine fiber generation type fiber is used. Alternatively, the fine fiber may be directly spun. In addition, as a specific example of the ultrafine fiber generating type fiber other than the sea-island type fiber, a plurality of ultrafine fibers are formed by lightly bonding immediately after spinning, and a plurality of ultrafine fibers are formed by unraveling by mechanical operation. Examples of such a separation-dividing fiber and a petal-type fiber in which a plurality of resins are alternately gathered in a petal shape in the melt spinning process are used, and any fiber that can form ultrafine fibers is used without particular limitation. .

  As specific examples of the resin that is an island component of the sea-island type fiber and forms ultrafine fibers, the above-described polyester resins such as PET and polyamide resins such as polyamide 6 are preferably used.

  It should be noted that the resin for forming the ultrafine fiber is various additives within a range not impairing the object and effect of the present invention, specifically, for example, a catalyst, an anti-coloring agent, a heat-resistant agent, a flame retardant, a lubricant, Antifouling agent, fluorescent brightening agent, matting agent, coloring agent, gloss improver, antistatic agent, fragrance, deodorant, antibacterial agent, acaricide, inorganic fine particles etc. may be blended as required Good.

  The sea component of the sea-island fiber is a component that is selectively extracted and removed by a solvent or selectively decomposed and removed by hot water or a decomposing agent when the sea-island fiber is converted into a fiber bundle of ultrafine fibers. . Specific examples of the resin for forming the sea component of the sea-island fiber include, for example, polyethylene, polypropylene, polystyrene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, styrene-ethylene copolymer, styrene- Examples thereof include acrylic copolymers and polyvinyl alcohol resins such as water-soluble thermoplastic polyvinyl alcohol (PVA).

  As a method for forming a fiber web, there is a method of forming a long fiber web without cutting sea-island long fibers spun by a spunbond method or the like. The sea-island fiber long fiber web may be produced by, for example, extruding a sea component polymer and an island component polymer from a composite spinning die to melt-spin the sea-island type fiber, and discharging the sea-island type fiber discharged from the die. After cooling with a cooling device, it is pulled down with a high-speed air flow at a speed corresponding to a take-up speed of 1000 to 6000 m / min, using a suction device such as an air jet nozzle, and a mobile net etc. It is formed by depositing on the collecting surface. Further, if necessary, the obtained long fiber web may be pressed to be partially crimped to stabilize the form.

  A plurality of webs obtained in this manner are stacked and lapped using a cross wrapper or the like to form a sea-island fiber fiber web.

  And the fiber entanglement sheet | seat of a sea island type fiber is formed by carrying out the entanglement process of the fiber web of a sea island type fiber. Specifically, the needle punching process is performed under the condition that at least one barb penetrates the fiber web of sea-island type fibers simultaneously or alternately from both outer sides. In addition, as the entanglement processing method, a method of entanglement with a water entangling machine using a water flow instead of the needle punch may be used. In this way, a fiber entangled sheet of sea island type fibers is formed. Moreover, the fiber-entangled sheet of sea-island type fibers may be subjected to heat shrink treatment as necessary. The entangled state is further densified by the heat shrink treatment. Further, it may be further densified by hot pressing.

  By converting the sea-island fibers contained in the fiber-entangled sheet of sea-island fibers obtained as described above into ultrafine fibers, the sea-island fibers are converted into ultrafine fibers and a nonwoven fabric of ultrafine fibers is formed. Specifically, for example, a seaming type fiber entangled sheet is a solvent or decomposition that selectively dissolves or decomposes only the resin that forms the sea component without dissolving and decomposing the resin that forms the island component. The method of processing with an agent is mentioned. In this way, a nonwoven fabric of ultrafine fibers forming a fiber bundle is obtained. The nonwoven fabric may be further densified by hot pressing. Densification is further achieved by hot pressing.

The average fineness of the ultrafine fibers is not particularly limited, but the average diameter is preferably 0.5 to 10 μm, more preferably 1 to 5 μm.

  And the long fiber in the obtained nonwoven fabric is restrained with binder resin. Specifically, for example, the nonwoven fabric is impregnated with a binder resin emulsion, and then dried to be solidified. The binder resin is not particularly limited as long as it is a resin that can restrain fibers, and examples thereof include polyurethane and acrylic resin as described above.

  In this way, a nonwoven fabric raw sheet in which the fiber bundle-like ultrafine fibers are bound with the binder resin is obtained.

  In addition, as shown in FIG. 2, only the long fibers 2 a of the surface layer are fused to each other by hot pressing the surface of the nonwoven fabric raw sheet that is exposed when wound on the grip, so-called A fiber silver surface may be formed. By forming the fiber silver surface, the design and wear resistance can be improved. The hot pressing is performed by, for example, a heated metal roll, and is preferably hot pressed at a linear pressure of 1 to 1000 N / mm. In addition, when the press temperature is too high, the long fibers are too fused and become a plate-like hard material, which is not preferable because moisture such as sweat is efficiently absorbed into the inside and difficult to diffuse inside. Tend.

  Further, as shown in FIG. 3, a surface layer 5 made of a polymer elastic body may be further laminated on the surface of the nonwoven fabric sheet on the side that is exposed when wound on the grip, if necessary. Thus, grip properties may be imparted. Specific examples of the polymer elastic body include urethane resin, acrylic resin, various elastomers and the like. The surface layer made of a polymer elastic body is formed by applying a gravure coating of an aqueous dispersion or aqueous solution of a polymer elastic body onto the surface that is exposed when wound on a non-woven fabric grip, and applying heat to the polymer elastic body. The method of drying and coagulating can be mentioned.

  In the continuous production process, the nonwoven fabric raw sheet thus formed is usually taken up in one direction and wound into a roll. And the grip tape base material is formed by cutting the wound-up nonwoven fabric sheet | seat in strip | belt shape, tape shape, or stripe shape by predetermined width. In the continuous production process of the raw sheet, the degree of orientation of the fibers in the nonwoven fabric is higher in the take-up direction than in the width direction. That is, in a normal nonwoven fabric manufacturing process, since the nonwoven fabric raw sheet is manufactured while being pulled in one direction, a tension is applied in the direction of pulling during manufacturing. For this reason, the degree of orientation of the fibers increases in the direction of take-up. At this time, when the grip tape base material is cut so that the longitudinal direction thereof coincides with the take-up direction of the original sheet, a grip tape is obtained in which the shrinkage of the dimension in the width direction is particularly suppressed when pulled in the longitudinal direction. It is done. The grip tape base material is usually provided with an adhesive layer or an adhesive layer on the back surface as necessary in order to facilitate fixing to the grip part, and the adhesive layer or adhesive layer is further made of release paper. Protected.

  Hereinafter, the present invention will be described more specifically with reference to examples. Note that the scope of the present invention is not limited to these examples.

[Example 1]
Water-soluble thermoplastic PVA resin is used as the sea component, PET with an isophthalic acid modification degree of 6 mol% is used as the island component, the number of islands per fiber is 25, and the sea component / island component is 25/75 (weight) Ratio), a sea-island filament was discharged from the die at 260 ° C. Then, the ejector pressure was adjusted so that the spinning speed was 3700 m / min, and sea-island long fibers having an average diameter of 17 μm were collected on the net. Then, the sea-island long fibers collected on the net are lightly pressed with a metal roll having a surface temperature of 42 ° C. to suppress fluffing on the surface and peel off from the net. By passing between the rolls and hot pressing, a long fiber web having a basis weight of 31 g / m ² on which the ultrafine fibers on the surface were temporarily fused was obtained.

Then, the obtained long fiber web was cross-wrapped to pile up 8 sheets, and this was sprayed with an anti-breaking oil agent.

An intertwined long fiber web was obtained.

Then, the long fiber web was heat-shrinked by dipping it in hot water at 70 ° C. for 14 seconds at a winding line speed of 10 m / min. Further, the modified PVA is dissolved and removed by repeating the dip nip treatment in 95 ° C. hot water to obtain a nonwoven fabric of ultrafine fibers in which fiber bundles containing 25 ultrafine fibers having an average diameter of 3 μm are entangled three-dimensionally. It was. The nonwoven fabric was adjusted to a nonwoven fabric having an apparent density of 0.62 g / cm ³ and a thickness of 0.82 mm by slicing and buffing.

  And the polyurethane emulsion was impregnated to the nonwoven fabric whose thickness was adjusted so that the polyurethane solid content was 6% by mass and dried. Then, only one surface of this nonwoven fabric was hot-pressed at 150 ° C. to fuse the surface long fibers to form a fiber silver surface. Thus, the nonwoven fabric raw fabric sheet containing the nonwoven fabric of the ultrafine fiber and the polyurethane to which the ultrafine fiber was fixed was obtained. The original fabric sheet was wound into a roll. And the grip tape base material with a thickness of 0.8 mm was formed by cutting in a continuous process into a stripe shape with a width of 20 mm while pulling out the original fabric sheet from the roll of the obtained nonwoven fabric original fabric sheet. And the adhesion layer was formed in the back surface of a grip tape base material, and also the adhesion layer was protected with the release paper. In this way, a grip tape was obtained. And the obtained grip tape was evaluated in accordance with the following method.

[Shrinkage of grip tape in width direction]
The obtained grip tape was cut into a length of 160 mm to prepare a test piece. Then, the obtained test piece was pulled by a tensile test using a universal testing machine under the conditions of a distance between chucks of 100 mm and a pulling speed of 100 mm / second, and the width dimension at the center between the chucks when measured to 110% was measured. did. Then, the reduction ratio of the width with respect to the original width of 25 mm at that time is expressed by the following formula: Reduction ratio (%) = [(original width−width after 110% tension) / original width] × 100
Calculated by The evaluation was performed at N = 5. As a result, the average thickness reduction rate was 4.0%.

[Water absorption diffusion rate]

The area (unit: cm ² ) was measured. As a result, the diffusion area was about 32 cm ² .

[Example 2]
PET long fibers having an average diameter of 17 μm were collected on a net to obtain a nonwoven fabric with an apparent density of 0.06 g / cm ³ . Then, in the same manner as in Example 1, a nonwoven fabric raw sheet containing a nonwoven fabric of long fibers and polyurethane to which the long fibers were fixed was obtained. In addition, the surface of the nonwoven fabric was subjected to a process of fusing the long fibers on the surface by hot pressing in the same manner as in Example 1. A grip tape base having a thickness of 0.8 mm was obtained in the same manner as in Example 1 except that the nonwoven fabric of PET long fibers having an average diameter of 17 μm obtained as described above was used instead of the nonwoven fabric of ultrafine fibers of Example 1. A material was formed. And the grip tape was manufactured like Example 1, and it evaluated similarly to Example 1. FIG. As a result, the average thickness reduction rate due to shrinkage in the width direction of the obtained grip tape was 3.8%. The diffusion area showing the water absorption diffusion rate was about 15 cm ² .

[Comparative example]
A PET fiber having an average diameter of 17 μm was melt-spun to obtain a filament. And after crimping the obtained filament, it cut | disconnected and produced the short fiber of fiber length 51mm. The obtained short fibers were put on a card and further cross-wrapped to obtain a nonwoven fabric having an apparent density of 0.19 g / cm ³ and a thickness of 2.6 mm. Then, in the same manner as in Example 1, a nonwoven fabric raw sheet containing a nonwoven fabric of short fibers of PET fibers having an average diameter of 17 μm and polyurethane to which the short fibers are fixed was obtained. In addition, the surface of the nonwoven fabric was subjected to a process of fusing the long fibers on the surface by hot pressing in the same manner as in Example 1. A grip tape base having a thickness of 0.8 mm was used in the same manner as in Example 1 except that the nonwoven fabric of PET short fibers having an average diameter of 17 μm obtained as described above was used in place of the ultrafine fiber nonwoven fabric of Example 1. A material was formed. And the grip tape was manufactured like Example 1, and it evaluated similarly to Example 1. FIG. As a result, the average thickness reduction rate due to shrinkage in the width direction of the grip tape was 8%. The diffusion area showing the water absorption diffusion rate was about 15 cm ² .

  From the results of Examples, the grip tapes containing the nonwoven fabrics of long fibers obtained in Example 1 and Example 2 both showed little shrinkage in the width direction of the grip tape when tension was applied. On the other hand, the grip tape containing the non-woven fabric of long fibers obtained in the comparative example had a large shrinkage. In addition, the grip tape of Example 1 including a non-woven fabric of ultrafine fibers is significantly more diffusive in absorbing moisture adhering to the surface than the grip tape of Example 2 including a non-woven fabric of normal fibers. It was excellent.
