Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to grips of exercise equipment such as rackets, golf clubs, bats, palm surfaces such as gloves and gloves, cushions, sofa cushions, vehicle mats and rugs. The present invention relates to a non-slip material which is used for the back surface of the shoulder, the shoulder back shoulder part, etc., and holds it so as not to slip from abutting objects such as the palm, floor, and shoulder surface of clothes.

[Conventional technology]

Rubber products have a large friction coefficient, and rubber molded products that have an uneven surface formed by embossing, sponge sheets that have uneven surfaces due to air bubble marks, and rubberized cloth coated with a rubber solution are used as anti-skid materials. .

[Problems to be solved by the invention]

Looking at the conventional rubber anti-slip material, the density of the protrusions formed by embossing is fine and they are planted at intervals of 1 mm and a height of 1 to 2 mm, and the protrusion surface is a smooth surface that does not absorb moisture. When it is used in a place where sweat is accumulated between the palm and the abutting object like a handle, the accumulated sweat acts as a lubricant, so that the anti-slip effect is not sufficiently exerted.

In this respect, since the sponge sheet is a porous body, the surface area of the rubber film is large, and it takes a certain amount of time for sweat water to collect in the internal pores, so it has a better anti-slip effect than rubberized cloth or embossed products. Are better. On the other hand, since the whole structure is composed of pore walls of thin rubber film, it lacks wear resistance and has a grip handle of exercise equipment where impact is repeatedly applied, and a shoulder back shoulder part that constantly receives a heavy load. It lacks durability as a non-slip material.

[Object of the Invention]

The present invention aims to eliminate such defects of conventional products, and obtain a durable anti-slip material that exerts a sufficient anti-slip effect by using it in a place where moisture is easily applied or a place where a strong external force acts. To do.

[Structure of Invention]

The present invention is a moquette, velveteen, a cut pile such as pile knit or a pile length of the loop pile fabric 11 having a pile length of 5 mm or less, and the surface of each fiber 12 is coated with a resin or resin composition film 14 having rubber viscoelasticity. The gist of the invention is to form a non-slip material 15 by coating.

The most characteristic anti-slip material 15 of the present invention is the cloth body 11
On the surface of the fiber, looped fibers 12 are densely planted with the narwhal hair 13 protruding to a height of 0.5 to 2 mm, and the surface of the narwhal fiber 12 is coated with a film 14 of a resin or resin composition having rubber viscoelasticity. Composed of a membrane.

The loop hair 13 can be formed by a loop pile 16 made by a tufting machine, a moquette loom, a knitting machine, or a loop-shaped raised fluff of plain woven cloth or non-woven cloth.

It should be noted here that the ring hair 13 in the present invention is
It doesn't mean Rina (loop pile 16) with thick thread,
In addition, it does not mean simply a thread that is raised on the surface of the fabric like a float of satin weave. That is, to describe in detail the ring hair 13 in the present invention, it means that the fibers 12 having a fineness of 20 denier or less are individually looped and form a void 17 surrounded therein, and thus, for example, The loop pile 16 formed by twisting yarns having a total denier of 29 or more, which is composed of dozens of filaments 12, is not to be opened to the extent that the fibers 12 are separated by brushing or brushing treatment. Not applicable,
In the case of a plain-woven knitted fabric or a non-woven fabric, the raised length L from the root to the root of the raised fluff fibers raised from the fabric body is less than twice the height H (L ≦ 2H) If it does not stand out as it is drawn, it will not be used as the naruna hair referred to in the present invention.

At least 1 cm of loop hair 13 protruding in a loop like that
The density must be 100 or more, preferably 1000 or more per ² and must be dense enough to be entangled. For that purpose, the loop hair 16 may be formed as a loop pile 16 which is a filament yarn or a sweet twisted or non-twisted spun yarn, and is preferably nap-treated to separate and open the fibers 12 constituting the loop pile 16, and between them. It is advisable to create fine gaps, and for that purpose crimped fibers may be used.

The rubber viscoelasticity of the film 14 formed by the resin or resin composition used in the present invention is indicated by the flexibility and friction coefficient of the resin composition of the film 14, and the rubber hardness indicated by JIS-K-6301 is 90. Below [Hs], the coefficient of friction on a flat steel plate surface is
A value of 0.5 or more means the physical properties of the film 14 that elastically deforms without plastic deformation.A rubber hardness of 40 to 80 (Hs) and a coefficient of friction of 0.7 or more can be used to obtain good results. .

The rubber hardness of nylon and polyethylene is approximately 100 [H
friction coefficient is 0.4 or less (0.37 for nylon and 0.27 for polyethylene).

Natural rubber, SB is a resin that exhibits such rubber viscoelasticity.
Emulsion / latex or organic solvent solution of synthetic rubber such as R and NBR and synthetic resin such as ethylene / vinyl acetate copolymer resin type, acrylic resin type and polyurethane resin type is used.

To coat the surface of the Nana hair fiber 12 with these resins 14,
The resin solution may be applied to the cloth 11 by a spray method, a roll coater method, a dip nip method, or the like.

In this case, however, it should be noted that these resin solutions or dispersions should be diluted to a sufficiently low viscosity so that the voids 17 in the nanah hair 13 may be closed or filled with resin, It is to prevent the hairs from clumping together in a ball or lump.

For that purpose, it can be said that it is a good idea to foam and apply the resin solution or dispersion.

〔The invention's effect〕

The surface of the non-slip material 15 of the present invention does not undergo plastic deformation and has a rubber hardness of 90 [H
s] or less, it is composed of the resin film 14 having a friction coefficient of 0.5 or more and excellent in rubber viscoelasticity, has a high adhesion to the abutting object 19 and a large friction coefficient, and therefore exhibits an excellent anti-slip effect.

Then, the resin layer 14 is finely protruded, and the Nana hair fiber 12 is formed.
Since it is thinly formed on the surface of the anti-slip material, the area of the resin film 14 occupying the surface of the anti-slip material is much larger than the surface area of the anti-slip material 15, and the surface shape of the fluffy or uneven rough contact object 19 The resin film 14 does not cause peeling damage even if an external force acts to displace the anti-slip material 15 and the abutting object 19 from each other. Film
No fracture detachment of 14 also occurs.

This loop hair 12 is entwined with the fibers inside the fabric body 11 whose base is both ends to form a deep rooted loop hair 13, and the loop hair 13 is a minute one having a length of 2 mm or less. Therefore, even if an external force is applied, it is not extracted, and the shape is always elastically restored to maintain a loop shape, and when the contacting object 19 is fluffy or rough and rough, the ring hair 13 is contacted. Since it is caught on the fluff or convex portion of the joint, an excellent anti-slip effect far exceeding the anti-slip effect due to only the friction coefficient of the resin film 14 is produced.

In addition, the surface of the non-slip material 15 of the present invention has a densely protruding ring hair 13.
Moisture or water that is present or is present between the contact object 19 and the abutting material 19 is absorbed in the porous layer of the narwhal hair and does not act like a lubricant, so that it is slipped by the moisture and water. Stop material 15
The anti-slip effect of is not disturbed.

Since the fabric 11 made of fiber is used as the base material, the anti-slip material 15 of the present invention is used.
Is flexible and tough, and can be pulled tightly around a grip handle to be wrapped tightly, and also exhibits excellent durability when used as a backing material for mats, shoulder bags and shoulder straps.

As described above, the anti-slip material 15 of the present invention, even under a moisture atmosphere,
In addition, it is extremely practical because it has an excellent anti-slip effect and durability against rough contact objects.

[Anti-slip test]

Cut pile rug, cotton cloth, plywood (horizontal object 19)
Samples of the warp knit pile knit fabric (blank) of the example, the example and the comparative example and the untreated sample are attached to the width 5c.
Test pieces 20 are cut into m and length of 20 cm, placed on a rug, cotton cloth and plywood 19, respectively, and a 5 cm square weight (weight 1 kg) with a square bottom is placed on one end of each of the test pieces 20. The sample was placed, held by a clip 22 having a width of 5 cm at the other end, and pulled in parallel with the horizontal table 18 to measure the tension at the start of each slide.

As a result, as shown in the following table, according to the examples of the present invention, the test pieces required a larger tension than any of the comparative examples with respect to the rug, the cotton cloth, and the plywood.

In addition, in the examples and the samples of the examples, the resin plastic material sprayed sufficiently penetrates into the back surface (non-pile surface), and the surface of the fiber is also coated with the resin plastic material in the same manner as the Nana hair fiber 12. It was However, in the sample of the comparative example, the resin plastic material did not penetrate to the back surface (non-pile surface), and the surface of the fiber was in an untreated state like the blank.

As is clear from the above data, the warp knit pile knit fabric has a slippery surface than the back surface, and the coated surface of the resin composition has slippery resistance than the non-coated surface of the blank.

Examine this point in more detail, and explain the case where the abutment 19 is a cotton cloth. In the blank, Nana hair is 180 g better in slip resistance than the back cotton, which is considered to be due to the Nana hair. . Further, the slip resistance of the backing cotton (non-pile side) of the example and the blank is 120 g in the example and 970 g in the example.
Each is superior to the blank, which is considered to be due to the rubber viscoelasticity of the resin composition.

However, in any of the examples, the slip resistance of the naena hair surface is 250 g (= 930-380-180-120) in the embodiment rather than the total amount of the effects due to those naena hair and rubber viscoelasticity. )
Further, the examples show high slip resistance as 330 g (= 1860-380-180-970), and in comparison, it is considered that the comparative examples are caused only by the unevenness of the crushed rubber particles or the rubber viscoelasticity. Compared to the back surface of the blank, only a slight effect of about 80 g is recognized.

Thus, in the case where the abutment 19 is a cotton cloth, a synergistic effect due to the nena hair and rubber viscoelasticity is recognized in the slip resistance of the anti-slip material of the present invention. In the case of the cut pile surface, 210 g (= 1660-600-470) in the embodiment.
-380), in the example, 30 g (= 1990-600-470-89)
0) In addition, when the abutment 19 is a smooth surface of the decorative plywood, 150 g (= 440-240-20-30) in the embodiment, 16 in the embodiment.
It is recognized as 0 g (= 1100-240-20-680).

As described above, it was confirmed in the examples that the anti-slip material 15 of the present invention has an excellent anti-slip effect.
