Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an artificial leather golf glove. More specifically, the present invention relates to artificial leather golf gloves that have good golf club grip and fit.

Conventionally, natural leather has been mainly used as golf gloves, but the ones with good grip and fit tend to tear easily, become black due to friction with the grip and sweat from the hands, and are difficult to wash. Due to the lack of functionality, such as the inability to wear gloves, better materials for golf gloves have been sought. In contrast, in recent years, suede-like types of artificial leather have been used as golf gloves, and are said to be more durable and less likely to tear.
Its functionality has improved, such as the ability to wash it with water. However, in terms of the essential fit with the grip of a golf club (regardless of whether it is made of rubber or leather), it is still inferior in that it tends to become loose, so there is a need for an even better grip.

The object of the present invention is to provide an artificial leather golf glove having such a grip and fins 1 and excellent properties. Moreover, the present invention provides artificial leather golf gloves that are excellent in appearance quality, softness, and suppleness.

That is, the artificial leather golf glove of the present invention has a fibrous grain layer in which ultrafine fibers branched from an ultrafine fiber bundle or bundles thereof are densely intertwined and resin is present in the voids. Because it comes into contact with the grip of a golf glove, it has a completely different fit and fit, especially in grips, than conventional silver artificial leather with a silver surface layer of polyurethane film or suede-like artificial leather with a napped layer of ultra-fine fibers. It exhibits a snug fit. Moreover, since the fiber itself is continuous with the grain layer inside, it has good durability against peeling of the grain surface or tearing due to shearing, and because it is made of artificial leather, it can be easily washed. It becomes a golf glove.

The ultrafine fibers of 0.05 denier or more used in the present invention are preferably used after being modified into ultrafine fibers at an appropriate time during the processing process using ultrafine fiber-forming fibers described below. In other words, the ultrafine fiber-forming fiber used in the present invention is, for example, a fiber made by gathering ultrafine fibers immediately after spinning and lightly adhering them into a single fiber, or a fiber in which one component is radially interposed between other components. Chrysanthemum-shaped cross-section fiber, multilayer bimetallic fiber.

Multilayer bimetallic fiber with a doughnut-shaped cross section, sea-island fiber made by melt-mixing and spinning two or more components, and a large number of ultrafine fibers continuous in the fiber axis direction, which are arranged and aggregated and bonded and/or partially bonded with other components. Wood fibers are formed by polymeric interlayer arrays such as fibers.

Two or more types of these fibers may be mixed or used in combination. Ultrafine fiber-forming fibers having a cross section in which a plurality of cores are interveningly bonded and/or partially bonded by other components can be relatively easily formed into ultrafine fibers by applying physical action or removing bonded components. It is used cleverly because it can be obtained. Further, when at least one component is dissolved and removed, preferably 0.05 denier or less, more preferably o,
Multi-component ultrafine fiber-forming fibers that yield bundles of fibers mainly consisting of ultrafine fibers of o o i or less are more preferred because they yield a leather-like sheet material with a particularly supple texture and smooth surface. used.

Further, the ultrafine fibers in the present invention are made of a polymeric substance having fiber-forming ability.1 For example, nylon 6° nylon 6
6. Nylon 12. Polyamides such as copolymerized nylon,
polyethylene terephthalate.

Polyesters such as copolymerized polyethylene terephthalate, polybutylene terephthalate, and copolymerized polybutylene terephthalate, polyolefins such as polyethylene and polypropylene, and polyurethane.

Examples include polyacrylonitrile and vinyl polymers. In addition, examples of the binding component or the dissolving and removing component of the microfiber-forming fiber include polystyrene, polyethylene, polypropylene, polyamide, polyurethane,
Copolymerized polyethylene terephthalate, copolymerized polyvinyl alcohol, copolymerized polyvinyl alcohol, styrene-acrylonitrile copolymer, easily soluble in alkaline solutions,
A copolymer of styrene and a higher alcohol ester of acrylic acid and/or a higher alcohol ester of methacrylic acid is used. Polystyrene, styrene-acrylonitrile copolymers, copolymers of styrene and higher alcohol esters of acrylic acid and/or higher alcohol esters of methacrylic acid are preferably used in terms of ease of spinning and ease of dissolution and removal. . Furthermore, it is possible to obtain fibers with a high draw ratio and high strength.
Higher alcohol ester of tyrene and acrylic acid and/or
Alternatively, a copolymer of methacrylic acid with a higher alcohol ester is more preferably used.

In addition, in terms of making the ultrafine fibers easier to branch,
It is preferable to mix 0.5 to 60 weight percent of a polymer such as polyethylene glycol with the binding component or the dissolution/removal component. The fineness of such microfiber-forming fibers is not particularly limited, but is preferably from 0.6 to 10 deniers from the viewpoint of stability during spinning and ease of sheet formation.

The ultrafine fibers in the grain layer of the present invention preferably have a fineness of 005 denier or less. If the fiber is thicker than 0.05 denier, the stiffness of the fiber is too high and the flexibility of the grain layer and the form of wrinkles on the surface are impaired. Cracks are likely to occur due to rubbing, etc., resulting in unevenness on the surface. It is difficult to form a dense and supple grain layer. Preferably 0.05 denier or less.

More preferably, by using ultrafine fibers with a denier of o or o o i or less, the fibers can be intertwined closely for the first time, and have a grain layer that is smooth and pliable, does not easily crack, and is comfortable in the hand. A leather-like sheet material is obtained.

The fiber structure in the grain layer of the leather-like sheet of the present invention is comprised of ultrafine fibers and /'! , or their bundles must be closely intertwined with each other. In other words, the fiber entanglement density is high. One way to measure the fiber entanglement density is to measure the distance between fiber entanglement points, which will be described later.
It is necessary to have the following entanglement density. This value is larger than 200 μ, for example, a fiber structure with little entanglement in which the fibers are entangled only by needle punching, or a structure in which ultrafine fibers or bundles thereof are simply arranged in a plane, or another ultrafine fiber size. Landscaping structures in which fibers or their bundles grow densely like fluff on the surface of the base material and are left to rest have little or no intertwining of the fibers, and are therefore susceptible to abrasion, kneading, and shearing force. When this happens, the surface tends to become fluffy and cracks are likely to occur, which is undesirable. In order to eliminate these shortcomings.

The distance between fiber entanglement points must be 200μ or less. If it is less than 100μ, favorable results can be obtained.

Here, the distance between fiber entanglement points is a value determined by the method of Tsuki, and is a measure of the density of intertwining of fibers, and the smaller the value, the more dense the intertwining is. . FIG. 1 is an enlarged schematic diagram of the constituent fibers in the grain layer when observed from the surface side. The constituent fibers are f
1 + f2 + fx r......, and the point where any two fibers f, f2 are intertwined is al, and the fiber f on the top at aI is Trace the fibers to the point where they intersect under the fibers, and let the intersecting point be a, (intersection point of f and f). Similarly, it is assumed that J l a41 aB + .

Next, the straight horizontal distance a between the intersecting points thus determined,

. . . are measured, and the average value of these many measured values is taken as the distance between fiber entanglement points.

In addition, the lower layer of the grain layer is mainly composed of ultrafine fiber bundles, and the grain layer's ultrafine fibers and/or their bundles are branched and more densely intertwined ultrafine fiber bundles of the lower layer. , the fibers are substantially continuous in the grain layer and the lower layer,
In addition, a fiber structure in which the degree of branching continuously changes at the boundary between the two layers is preferably used because a golf glove with a unified feel can be obtained and the grain layer and the lower layer will not peel off. . Here, the thickness of the ultrafine fiber bundles in the grain layer does not need to be the same for all bundles, but is as thin as possible compared to the thickness of the bundle in the lower layer (the number of fibers included in the bundle is smaller than that in the bundle in the lower layer). It is preferable that the surface of the sheet is less likely to have unevenness on the surface of the sheet. In addition, golf gloves made from conventional leather-like sheets that use nonwoven fabric as a base material are easy to stretch due to external force and deform plastically when the base material is made only of fibers, so it is difficult to return to the original shape. <.

To prevent this, resin has been applied to the base material.

However, the golf glove of the present invention, which has a fiber structure in which ultrafine fibers and bundles of /-1: bamboo shoots are densely intertwined, does not stretch abnormally even if resin is not added to the lower layer, and has good shape retention. is good. This is also a major feature of the present invention.

Yes, a resin such as polyurethane distomer may be applied to the lower layer, and the amount of resin applied is about 7
It depends on the purpose of use of the object. When used for golf gloves, the amount applied is preferably 0 to 50 parts based on the weight of the fiber. Examples of the resin used for the silver layer include polyamide, polyester, polyvinyl chloride, polyacrylate copolymer, polyurethane, neoprene, and styrene-butadiene copolymer.

Acrylonitrile butadiene copolymer, polyamino acid,
Synthetic resins or natural polymer resins such as polyamino acid polyurethane copolymers and silicone resins.

Or a mixture of these resins. Furthermore, depending on the requirements, plasticizers, fillers, stabilizers, pigments, and dyes.

A crosslinking agent or the like may be added. Polyurethane resins or polyurethane resins to which other resins or additives are added are preferably used because they provide a grain layer with particularly soft texture and feel and good bending resistance. The resin adhesion structure of the silver layer is not particularly limited and may vary depending on the purpose, but if flexibility and soft feel are particularly required, a structure in which more resin is adhered closer to the surface of the bride layer may be used. or those with a structure in which the very thin layer on the outermost surface of the grain layer has a particularly large amount of resin attached, and the rest has no resin attached at all or only a small amount if it is attached.

It is preferable to have a structure in which the resin on the surface is non-porous and the rest is porous. ′! ! Ta. In cases where particularly high scratch resistance is required, a structure in which the voids in the grain layer are filled with resin almost without gaps is preferred.

As a method for manufacturing the golf glove of the present invention.

First, the ultrafine fiber-forming fiber is
Manufactured using the spinning device shown in Japanese Patent No. 369.

After being stapled, a web is formed by passing through a card and a black horn, which is then subjected to needling and punching to intertwine the ultrafine fiber-forming fibers and form a fiber sheet. Alternatively, following the spinning of the microfiber-forming fibers, they are stretched and placed randomly on a wire mesh, and the obtained web is needle punched in the same manner as described above to form a fiber sheet. Alternatively, the ultra-fine fiber-forming fibers are placed on a non-woven fabric or woven nine-knit fabric made of ordinary fibers or other ultra-fine fiber-forming fibers, and are entangled and inseparably integrated to form a fiber sheet. Next, the fiber sheet obtained in this manner is brought into contact with a raised fluid stream to branch the portion corresponding to the grain layer into ultrafine fibers and/or bundles thereof, and at the same time to entangle them densely. The fluid here refers to liquid or gas, in special cases.

It may contain extremely fine solids.

Water is most preferably used in terms of ease of handling, cost, and amount of collision energy as a fluid.

Furthermore, depending on the purpose, various organic solvents capable of dissolving some components of the ultrafine fiber-forming fibers, or aqueous solutions of alkalis or acids such as sodium hydroxide can also be used. These fluids are pressurized and injected through small-diameter nozzles or narrowly spaced slits to create a high-speed columnar flow or curtain-like flow.

The fibers are brought into contact with the fiber sheet to branch and entangle the fibers. The pressure applied to the liquid varies depending on the ease of branching of the ultrafine fiber-forming fibers or ultrafine fiber bundles.For fibers that are easy to branch, a relatively low pressure of 5 to 7047 cm2 may be sufficient, but for fibers that are difficult to branch, a relatively low pressure of 70 cm2 is sufficient. ~30
A high pressure of 0.147 cm" is required. However, it is also possible to increase the degree of p-branching and entanglement by increasing the number of contacts.

The pressure may be varied with each contact. After that,
If necessary to make the used ultrafine fiber-forming fibers ultrafine, the obtained fiber sheet is treated with a solvent that dissolves some components of the ultrafine fiber-forming fibers to dissolve some of the components. Remove.

I cut it. If necessary, it is impregnated with a solution or dispersion of a resin such as polyurethane disstomer and solidified by a wet or dry method. Here, the part of the component may be dissolved and removed before the treatment with the high-speed fluid flow. In this case, by dissolving and removing the part of the component, the ultrafine fiber-forming fibers of the fiber sheet become a bundle of ultrafine fibers. This is a preferred method because it is metamorphosed and can be easily and highly branched and entangled at low fluid pressures. In addition, high-speed fluid flow treatment may be performed before and after the step of dissolving and removing the partial components.
Also. In addition to the above steps, the step of applying the resin can be carried out between the high-speed fluid flow treatment step and the step of dissolving and removing some components of the fibers.

In this case, it is necessary that the applied resin is not dissolved by the solvent used to dissolve and remove the partial component, but the partial component must exist between the resin and the ultrafine fiber bundle of the obtained fiber sheet. This is the preferred method for making the texture flexible, as it frees up space and increases the degree of freedom for opposing movements. On the other hand, performing high-speed fluid flow treatment after applying the resin is not a desirable method because when a large amount of resin is applied, the fibers are bound by the resin, so branching and entanglement hardly occur. . After that, the solution or dispersion of the resin for the grain layer described above is applied to the layer of the obtained fiber sheet in which the ultrafine fibers and/or their bundles are intertwined, by reverse roll coating.
Clavia coating.

Apply by knife coating, slit coating, spraying, etc., and harden by wet or dry method.
. ~7. Alternatively, the fibers and resin are stacked on the -1 side, pressed, and heated as necessary to integrate the fibers and resin and at the same time smooth the surface.

Here, it is also a preferable method to subject the fiber sheet to a treatment such as pressing to smooth the surface before applying the resin. At this time, it is difficult to use an embossing roll with a textured surface or a texture-forming sheet roll because it allows integration, smoothing, and texture-forming to be performed at the same time. Furthermore, if necessary, treatments such as applying a finishing agent, dyeing, and rubbing may be performed.In the golf glove of the present invention, the drape coefficient is preferably 0.3 to 0.7. Within this range, durability.

An extremely good fit can be obtained.

Here, the drape coefficient is a value measured by the method of J.E.S-:c, -1096.

Drapability is determined by the degree of branching and entanglement of the ultra-fine fiber-generating fibers, the presence or absence of binder resin and its application method (dry or wet), the amount of 9 types of binder resin applied, and the amount of antigreasing agent for the grain layer. The golf gloves of the present invention can be controlled by appropriately selecting two types, etc. 1, 9 The golf gloves of the present invention include
A load (round shape) with a thickness of 0.6 to 1.5 mm is suitable.

Furthermore, the golf glove of the present invention is made by sewing the above-mentioned artificial leather with the grain layer facing up as shown in FIG. If the grain layer is not exposed, like traditional suede-like artificial leather,
It is undesirable because it becomes slippery and difficult to fit. Those with holes in the fingers are very effective at allowing ventilation and sweat to escape.

The examples shown below are for the purpose of clarifying the present invention more clearly, and the present invention is not limited thereto.

Example 1 A polymer in such a form that one filament contains an extremely large number of Kyokuga fibers in a ratio of 45 parts of a mixture of 95 parts of polystyrene and 5 parts of polyethylene glycol as a binding component and 55 parts of polyethylene terephthalate as an ultrafine fiber component. A nonwoven fabric was made in the same manner as in Example 1 using 3.8 denier, 51 mm mutually arranged fibers.

The basis weight of this non-woven fabric is 400 g/m”, thickness ij 2
．． It was 0 ml11. One side of this nonwoven fabric has a pore size of 0
．． A columnar flow of water injected at a pressure of 1004/♂ using a nozzle with 1 mm holes arranged in a row at a pitch of 0.6 mm was brought into contact, and the pressure was increased to 30 kg/c five times under the same conditions.
The treatment was carried out twice at a lower temperature. Furthermore, it was placed in hot water at 95°C and subjected to a shrinkage treatment and a nip using a mangle. The thickness of the obtained interlaced nonwoven fabric was reduced to about 1.2 mm,
The average fineness of branches branched from water-treated fibers is approximately 0. O.D.
The 1-denier ultrafine fibers and their bundles were mainly densely and densely intertwined, and the surface had very few irregularities.

Next, after slicing into 0.8++nn, a paint made by adding carbon black and dye to a polyurethane solution was applied to the surface layer of the water-treated side using a gravure coater, dried and pressed to form a composite. Grain shaping was performed. Furthermore, polystyrene and polyethylene glycol were dissolved and removed using trichlorethylene, and the other side was blown to fluff the ultrafine fibers, and then dyed at a high temperature of 120'O using a disperse dye and finished as usual. The thickness was approximately 0.7 mm.

Furthermore, when golf gloves as shown in Fig. 2 were sewn from six materials: the artificial leather of the present invention, a commercially available napped type suede-like artificial leather, and a buttoned artificial leather having a thin polyurethane layer as a silver surface, golf gloves as shown in Fig. 1 were sewn. As shown in the table, the artificial leather golf glove of the present invention exhibited the most excellent properties, especially the fit with the grip.

Table 1 After removing the polyurethane and finishing agent from the grain layer of the golf glove of the present invention, the average distance between fiber entanglement points of the constituent fibers was measured and found to be 98μ.

Next, only the sheets in Table 2 are mixed thiolt p+p of polyethylene adipate and polybutylene adipate.
A prepolymer of '-diphenylmethane diisocyanate was chain-extended with ethylene glycol, and the polyurethane was impregnated with a 7-tidimethylformamide (hereinafter referred to as DMF) solution. It was introduced and solidified. Thereafter, it was sufficiently washed in hot water at 8 D'c to remove DMF.

Next, from the surface of these four types of sheets, a solution of pigment added to a 10% solution of polyurethane, which has the same composition as the polyurethane used for impregnation but is slightly harder, was applied using a gravure coater. After drying, it was pressed through a heated embossing roll to emboss a leather-like grain pattern. Then, immerse it in trichlorethylene, immerse it, and twirl the squeezed solution.
The S resin was almost completely extracted and removed, and then dried.

Residual trichlorethylene was removed by evaporation, and then dyed using a jet dyeing machine at normal pressure.9 Finishing was carried out in a conventional manner. The thickness of all four types of sheets was approximately 0.5 mm.
