2. Description of the Related Art Conventionally, artificial leather has been used for various purposes, but a suede-like material has been favorably used especially for gloves that require air permeability. However, conventional suede-like artificial leather, although there is variation in fineness, since the upper layer to the lower layer of artificial leather are made of fibers of almost the same fineness, although there is flexibility when using relatively thick fibers, Lack of high-grade appearance and touch, and using relatively fine fibers, on the other hand, gives a high-quality appearance, but has the problem that the touch and texture are paper-like and the tensile strength is low. Was. As means for solving such a problem, for example, according to Japanese Patent Publication No. 48-11925, two fibers having different finenesses are used.
A method of laminating webs composed of at least one kind of fiber and integrating them by a needle punching method or the like is disclosed.
According to this method, artificial leather having a balance between flexibility and strength can be obtained, but when used for a suede-like sheet, fibers with different fineness are mixed on the surface by needle punch, so that touch quality is high. It is not suitable as a material for sports gloves that requires a balance of thinness, texture, and strength because it lacks a feeling and looks uneven in color after dyeing, so it can not give a high-quality appearance. Met.

DISCLOSURE OF THE INVENTION The present inventors have developed a sports glove having a high-grade appearance and touch, a texture close to that of natural leather, a non-slip effect when processed into a sports glove, and a fit to the hand. As a result of intensive studies on a suede-like leather-like sheet for use, the present invention was completed. That is, the present invention provides a layer (A) composed of ultrafine fibers (a) of 0.01 decitex or less, and a layer (B) composed of fine fibers (b) having an average diameter three times or more the diameter of the ultrafine fibers (a). Is the weight ratio (a) / (b) = 25 / 75-50 /
The nonwoven fabric laminated and entangled and integrated in the range of 50 contains an elastic polymer, and the surface on the side of the layer (A) is covered with raised hairs substantially consisting of only the ultrafine fibers (a). It is a suede-like leather-like sheet for sports gloves. And in this invention, the said leather-like sheet for sports gloves whose whole thickness is 0.4-0.6 mm is preferable. Further, the present invention is preferably a sports glove obtained by sewing the leather-like sheet such that the surface on the layer (A) side is outside the glove and the surface on the layer (B) side is inside. More preferably, the leather-like sheet is a sports glove sewn so that the direction in which the Young's modulus of the leather-like sheet is highest substantially coincides with the longitudinal direction of the sports glove.

Hereinafter, the present invention will be described in detail. The suede-finished leather-like sheet constituting the present invention has a web made of ultrafine fibers of 0.01 decitex or less (may be a fiber that generates such ultrafine fibers) and an average diameter of three times or more thereof. A nonwoven fabric obtained by laminating a web made of fine fibers having the following (which may be fibers that generate such fibers) and then entangled (in the case of fibers that generate the above fibers) Comprises a nonwoven fabric which has been subjected to a generation treatment, and an elastic polymer impregnated and coagulated therein. Hereinafter, a nonwoven fabric obtained by impregnating and coagulating an elastic polymer is simply referred to as a sheet. The fineness of the fiber (a) constituting the leather-like sheet needs to be 0.01 decitex or less, and preferably 0.005 to 0.5.
0001 decitex. If it exceeds 0.01 decitex, the tapped feel becomes rough, the fine gloss cannot be obtained, and the high-grade appearance is reduced. Furthermore, since the surface area of the fiber decreases, the anti-slip effect also tends to decrease. If it is less than 0.0001 decitex, the color developability after dyeing tends to decrease.
The fineness of the fiber (b) is a fineness having an average diameter three times or more that of the ultrafine fiber (a), and preferably the fineness is 1
０．００0.001 dtex. Preferably, the fineness of the fiber (b) is a fineness having an average diameter of at least four times that of the ultrafine fiber (a). Further, when the fineness of the fiber (b) exceeds 1 decitex, although fine fibers are present on the surface, a rough touch tends to be transmitted to the surface touch, and when it is less than 0.001 detex, the physical properties of the leather-like sheet are reduced. Tend to be lower. It is essential that the fineness of the fiber (b) be three times or more the average diameter of the fiber (a). If it is less than three times, each fiber itself also has a fineness distribution, so that the fineness difference between the two layers becomes small, and characteristics due to the lamination, for example, the elongation preventing effect is not exhibited.

[0005] As a method for producing ultrafine fibers or fine fibers, spinning methods such as a mixed spinning method and a composite spinning method using two or more kinds of polymers which are not compatible and have different solubility or degradability are used. Thereby, an ultrafine fiber-generating fiber having a cross-sectional shape of a sea-island structure or a splittable bonded structure is obtained, and a part (for example, a sea component) of the fiber is extracted or decomposed and removed, and the bonded portion is peeled off. A method of forming a sheet having a nap structure by extracting or decomposing and removing a part of the fiber (for example, sea component) to form a fine fiber, or discharging a fiber-forming polymer from a melt spinning nozzle. Immediately after the blown with high-speed gas to thin the fiber, it is possible to use a known method for producing a fine fiber such as a so-called melt blow method, but preferably from the management of fiber thickness and stability of the fine fiber, It is a method of via the serial microfine fiber-forming fiber.

[0006] The resin constituting the ultrafine fibers is not particularly limited, but aromatic polyesters such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, and copolyesters containing these as a main component, and nylon. Polymers selected from known resins such as polyamides such as -6, nylon-66 and nylon-610, and polyolefins such as polyethylene and polypropylene. Above all,
The aromatic polyesters and polyamides are preferable in that natural leather-like artificial leather can be obtained and dyeability is excellent. Further, a coloring agent such as carbon black may be added to these resins as long as the stability during spinning is not impaired.

[0007] Examples of the resin component constituting the ultrafine fiber-generating fiber which is extracted or decomposed and removed are polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, polystyrene, styrene-acryl. Examples include at least one polymer selected from polymers such as a system monomer copolymer, a styrene-ethylene copolymer, and a copolymerized polyester. Among them, polyethylene, polystyrene, copolymers mainly composed of these, and the like are preferable in terms of ease of extraction.

Next, a method of forming a base material using the above-mentioned ultrafine fibers or ultrafine fiber-generating fibers will be described. As a method of forming a nonwoven fabric, a known method, for example, a step of producing an entangled nonwoven fabric made of ultrafine fiber generating fibers, a step of impregnating and coagulating the entangled nonwoven fabric with an elastic polymer solution,
This can be achieved by sequentially performing the step of modifying the ultrafine fiber-generating fibers into ultrafine fibers. Needless to say, the step of modifying into ultrafine fibers and the step of impregnating and coagulating an elastic polymer may be reversed.

As a method for producing an entangled nonwoven fabric using the ultrafine fiber-generating fibers, the ultrafine fiber-generating fibers are subjected to spinning, drawing, heat treatment, crimping, cutting, and the like by a conventionally known method. A raw cotton of the same fiber is prepared, and the raw cotton is defibrated with a card and formed into a random web or a cross-wrap web with a weber.

[0010] At this time, a fiber layer composed of the fibers forming the fiber (a) and a fiber layer composed of the fibers forming the fiber (b) are laminated, and preferably, the fiber layer is formed of a web. The web is laminated and brought to the desired weight. The lamination weight ratio of the web composed of the fiber that forms the fiber (a) to the web composed of the fiber that forms the fiber (b) is determined after the formation of the fiber (a) and the fiber (b). (A) / (b) = 25 / 75-50 /
50, and more preferably (a) / (b) = 30 /
Lamination is performed so as to be 70 to 45/55. When the weight ratio of (a) is less than 25%, the fiber of (b) can be seen through or a part of the fiber comes out on the surface after dyeing.
The uniformity of the surface is reduced, which causes touch unevenness and dyeing unevenness. Further, since the effect of preventing stretch is reduced, when processed into sports gloves, repeated use of the gloves may cause the shape to be lost. If it exceeds 50%, the texture becomes hard.

[0011] The weight of the fiber per unit area of the laminate after laminating a fiber layer composed of the fiber that forms the fiber (a) and a fiber layer composed of the fiber that forms the fiber (b) The size is appropriately selected depending on the intended field of use of the final sports glove, and is generally 100 to 3000 g.
/ M ² is preferred. For the purpose of cost reduction, etc., an elastic polymer solution is impregnated and coagulated into a nonwoven fabric about twice the required weight, and then divided in the thickness direction with a band knife or the like, so that the nonwoven fabric can be efficiently processed at a time. One piece of substrate can also be manufactured. In this case, (a) / (b)
/ (A) and (b) / (a) / (b). Although not particularly limited, (a) / (b) /
The lamination of (a) is more preferable because a denser surface can be obtained more easily.

After laminating the web, an entangled nonwoven fabric is formed by performing an entanglement treatment using a known means, for example, a needle punching method. The number of needle punches and the conditions for needle punching vary depending on the shape of the needle used and the thickness of the web, but are generally 200 to 2500 punches / cm ^2.
It is better to set within the range. Here, a method of the needle punch will be described. In the following description,
(A) and (b) may mean a fiber that forms (a) or a fiber that forms (b). A needle punch typically pierces the needle evenly from both sides of the web and adjusts the piercing depth such that the barb portion of the needle penetrates the web completely to provide sufficient entanglement. However, in the present invention, in order to improve the uniformity of the fluffiness on the brushed surface, the smoothness of the touch, and the uniformity of the color after dyeing, the needle struck from the surface of the microfiber (a) is formed by a barb laminated. It is essential to hit to the depth to penetrate the web. Usually, the needle is hit to a depth where the barb penetrates the laminated web by about 0 to 5 mm. If the barb does not penetrate, the resulting leather-like sheet will have poor tensile and tear physical properties. on the other hand,
It is essential that the needle hitting from the surface (b) hits only to a depth where the barb portion does not penetrate the laminated web. Usually, the needle is hit under the condition that the barb stops just before protruding about 0 to 2 mm. Further, if the penetration depth of the needle is made shallow, the physical properties tend to decrease, and if the barb penetrates, the appearance is deteriorated for the reasons described above, which is not preferable. In the above description, the direction of the barb is such that the fiber is brought into the web when the needle is pierced into the web, and conversely, the fiber is brought into the web when the needle is pulled out. If the barb is oriented, the driving depth of the needle may be determined based on the above description.

Prior to the process of containing the elastic polymer, the surface of the entangled nonwoven fabric can be subjected to a smoothing treatment by a known method such as hot pressing, if necessary. When the fiber constituting the entangled nonwoven fabric is a sea-island type ultrafine fiber-generating fiber having, for example, polyethylene as a sea component and polyester or polyamide as a very fine island component, the sea component polyethylene is melted by hot pressing, The fusion of the fibers is particularly preferable because an entangled nonwoven fabric having extremely excellent surface smoothness can be obtained. In addition, when the fibers constituting the entangled nonwoven fabric are not multicomponent fibers that can be dissolved and removed as one component to be modified into ultrafine fibers, the elastic polymer contained therein is prevented from sticking to the fibers and hardening the hand. For this purpose, it is preferable to cover the fiber surface with a temporary filling material such as polyvinyl alcohol prior to the impregnation treatment, and to remove the temporary filling material after applying the elastic polymer. Also in the case where the ultra-fine processing is performed after the impregnation and coagulation of the elastic polymer, the provision of the temporary filling material at the stage of the entangled nonwoven fabric before the ultra-fine processing can provide a more flexible sheet.

As the elastic polymer to be contained in the entangled nonwoven fabric, known ones can be used, but it is preferable to use a polyurethane resin from the viewpoint of feeling. Preferred polyurethane resins are selected from the group consisting of polyester-based diols, polylactone-based diols, polycarbonate-based diols, and polyether-based diols obtained by reacting a diol with a dicarboxylic acid or an ester-forming derivative thereof as a soft segment. A so-called segmented polyurethane obtained by using at least one kind of polymer diol having a number average molecular weight of 500 to 5,000 and reacting this with a diisocyanate compound and a low molecular chain extender is used.

The diol compound constituting the soft segment is preferably a compound having 6 to 10 carbon atoms in terms of durability or leather-like texture.
Examples thereof include 3-methyl-1,5-pentanediol, 1,6-hexanediol, 2-methyl-1,8-octanediol, 1,9-nonanediol, and 1,10-decanediol. Representative examples of dicarboxylic acids include aliphatic dicarboxylic acids such as succinic acid, glutaric acid, adipic acid, azelaic acid and sebacic acid, and aromatic dicarboxylic acids such as terephthalic acid and isophthalic acid.

The number average molecular weight of the polymer diol is 500
If it is less than 10%, it is not preferable because it lacks flexibility and a natural leather-like texture cannot be obtained. When the number average molecular weight of the polymer diol exceeds 5,000, the urethane group concentration decreases, and it is difficult to obtain a well-balanced composition in flexibility, durability, heat resistance and hydrolysis resistance.
Examples of the diisocyanate compound include diphenylmethane-4,4′-diisocyanate, tolylene diisocyanate, isophorone diisocyanate, hexamethylene diisocyanate, dicyclohexylmethane-4,
4'-diisocyanate and the like. Examples of the low molecular chain extender include ethylene glycol, propylene glycol, butanediol, hexanediol,
Low-molecular compounds having two active hydrogen atoms having a molecular weight of 300 or less, such as N-methyldiethanolamine and ethylenediamine, may be mentioned. If necessary, a coagulation regulator, a stabilizer and the like may be added to the elastic polymer, and two or more polymers may be used in combination. Further, a coloring agent such as carbon black may be added.

The method of incorporating the elastic polymer into the entangled non-woven fabric is not particularly limited, but a method of directly impregnating the entangled non-woven fabric with the elastic polymer solution in view of the balance of the texture, and squeezing with a mangle if necessary. Also, a method of impregnating an elastic polymer solution while coating it with a coater is preferable. Further, from the viewpoint of a natural leather-like soft texture, the weight ratio between the fibers constituting the nonwoven fabric (the fibers after the ultrafine fiber treatment in the case of the ultrafine fiber generating fibers) and the elastic polymer is 20/80 to 95/95. / 5 is preferred, and more preferably in the range of 25/75 to 90/10. If the ratio of the fibers is too low, the leather-like sheet has a rubber-like texture, which is not preferable. If the ratio of the fibers is too high, the texture becomes a paper-like texture, and the target natural leather-like texture cannot be obtained.

After the elastic polymer is contained in the entangled non-woven fabric, a liquid which acts as a non-solvent for the island component of the elastic polymer and the microfine fiber-generating fibers and acts as a solvent or a decomposer for the sea component. To convert the microfiber-generating fibers into microfiber bundles to obtain a sheet comprising a microfiber entangled nonwoven fabric and an elastic polymer. Needless to say, the sheet may be formed by a method of modifying the ultrafine fiber-generating fibers into an ultrafine fiber bundle prior to containing the elastic polymer.

Surface raising of the sheet made of the obtained entangled nonwoven fabric of ultrafine fibers and an elastic polymer can be carried out by a known method such as buffing and styling. Since the fluff length to be raised affects the appearance such as the feel and gloss, the conditions for buffing and shaping, such as the number of sandpaper used for buffing, the speed of shaving,
By adjusting the pressing pressure or the like, a desired fluff length can be obtained.

The suede-finished leather-like sheet obtained as described above is dyed by a known method and used for sports gloves. About thickness, 0.4-0.6mm
Is preferred in terms of texture and strength. 0.4m
If it is less than m, the tensile properties and abrasion properties will be reduced, and if it exceeds 0.6 mm, the texture will be hard, and it is not suitable as a material requiring a delicate grip such as a golf glove. Regarding the adjustment of the thickness, there are a method of adjusting the basis weight of the web and the amount of the elastic polymer impregnated so as to have a desired thickness, and a method of adjusting the thickness by buffing a thick sheet with a buff. However, since the suede-finished leather-like sheet of the present invention has a structure in which fibers having different finenesses are laminated, the leather-like sheet is formed when one surface is shaved off by buffing or the like for thickness adjustment. The weight ratio of the fibers (a) and (b) is 25/75 as described above.
It is necessary not to deviate from the range of ~ 50/50.

Next, a method of processing the leather-like sheet into sports gloves will be described. Cutting and sewing of glove parts are performed by a generally used method. The leather-like sheet of the present invention may be used for any part of a glove, or may be used entirely. However, in order to make use of the anti-stretch effect and express a feeling of fit to the hand, it is preferable to use the part cut from the wrist to the index finger, and it is preferable to use the part on the back of the hand, which is under tension when used. The term "stretch preventing effect" as used herein refers to a recovery rate when a stress is released after being stretched, and is evaluated by a 30% stretching recovery rate (width) specified in JIS L-1096 in the present invention. 30% elongation recovery rate (horizontal)
According to the study of the present inventors, a value suitable for a sports glove is 70 to 90. If it is less than 70, the use of gloves will be repeated, and the elongation will not be fully recovered, which will cause the mold to lose shape. Conversely, if it exceeds 90, the rubber-like elastic behavior is obtained, which is different from the behavior of natural leather.

The artificial leather-like sheet of the present invention utilizes the high-grade appearance and touch to obtain a high-grade sports glove, so that the surface of the layer (A) composed of the ultrafine fibers (a) is made of gloves. It is preferable to sew so that the outer surface is on the side of the layer (B) made of the fine fibers (b), which is on the inner side. Even if the surface used is reversed, the physical properties of the glove itself do not change, but not only does it not provide a high-grade appearance, but also the anti-slip effect by using a layer made of extra-fine fibers with a larger surface area on the surface. descend.

When the leather-like sheet is processed into sports gloves, each part is cut so that the direction in which the leather-like sheet has the highest Young's modulus substantially coincides with the longitudinal direction of the sports glove. preferable. In general, the direction in which the leather-like sheet has the highest Young's modulus coincides with the direction of travel during production. As described above, artificial leather tends to have a high Young's modulus because tension is applied in the traveling direction at the time of production, and the Young's modulus tends to decrease in a direction at 90 degrees to the traveling direction. In addition,
Here, "substantially coincide" means that the angle is within a range of 30 degrees even if it is shifted. When gripping a golf club, baseball bat, or the like while wearing sports gloves, cut and sew the leather-like sheet so that the direction of the highest Young's modulus of the leather-like sheet matches the longitudinal direction of the glove, which is the direction in which the gloves are most stretched. Thereby, a sensation of fitting to the hand without stretching more than necessary can be obtained. Conversely, when the glove parts are cut and sewn so that the vertical direction of the glove and the direction of the highest Young's modulus of the leather-like sheet are shifted by 90 degrees, the finger part of the glove becomes tight and hard to bend. As a result, the gloves as a whole are stretched and lose their shape, and no fit is obtained.

The suede-finished leather-like sheet obtained as described above has a high-grade appearance and touch, has an anti-slip effect and an anti-stretch effect, and is suitable as a material for sports gloves. By using the surface with the raised fiber layer (A) on the outside and cutting and sewing the leather-like sheet so that the direction of the highest Young's modulus of the leather-like sheet and the longitudinal direction of the glove almost coincide with each other, a sport glove with a high fit can be obtained. can get.
