Its enthusiasm has also diversified, and recent leisure sports such as marine sports and sky sports are also very popular. As such marine sports and air sports products, there are: speedboat sailing, spinnaker, gliding parachute, hang glider, kiteboard, etc., and for this purpose, fiber cloth is used. Further, these sports fiber materials are excellent in light weight, strength, and the like, and Nylon fibers are used. These fabric materials for sports equipment require a high degree of weather resistance because they are used outdoors for a long period of time. Therefore, polyester fibers are gradually used without using weather resistant nylon. Patent Document 1 proposes a cloth for sports equipment using polyester fibers, and Patent Document 2 proposes a method in which a polyether oxide is adhered to a fabric using a rip-stop structure of a polyester fiber. A cloth material for sports equipment of resin and polyurethane resin. However, for such sportswear fabrics, not only weather resistance, but also ripping strength or abrasion resistance is required. For example, in the case of the fabric of the tree processing of 200936839, the tear strength is particularly required. Upgrade. Further, in Patent Document 3, in order to improve the tear strength, there is proposed a cloth to which a water repellent treatment is applied as a pretreatment before processing of the polyurethane resin. If the pre-water repellent treatment is carried out before the processing of the polyurethane resin, although the slip of the fiber is improved and the tear strength can be improved, it is easy to produce the adhesion mottle of the polyurethane resin, and tearing The shortcomings of the very large variation in crack strength have been confirmed by subsequent studies. [Patent Document 1] Japanese Patent Laid-Open No. Hei. No. Hei. No. Hei. No. Hei. No. 2005-97787 (Patent Document 3): Japanese Patent Publication No. Hei 4-59 1 39 It is an object of the invention to provide a fabric which is obtained by impregnating a fabric having a polyoxymethylene copolymerized polyurethane resin on a fabric having a polyester fiber as a main component, and having excellent tear strength. Sports equipment Q is made of cloth material. As a result of intensive investigation of the resin attached to the cloth for sports equipment, the present inventors have found that, if a polyoxymethylene copolymerized polyurethane resin is used, not only the excellent tear strength but also the improvement can be achieved. The fact of the abrasion strength' and the present invention has been completed based on the experience. The present invention relates to a cloth material for sports equipment, comprising: a base fabric made of a fabric containing polyester fibers as a main component, and impregnated and adhered to the base fabric as a main component; 6 - 200936839 Oxygen copolymerized polyurethane acetal resin impregnated adhesion layer, composite cloth, characterized in that: the mass of the base fabric is 20 to 8 〇g / m2, the quality of the impregnated adhesion layer The mass of the base fabric is 5 to 40% by mass, and the mass of the composite cloth is 21 to i〇0 g/m2, and the permeability of the composite cloth is 1.0 ml/cm 2 /sec. In the cloth material for sports equipment of the invention, the polyfluorene-oxygen copolymerized polyurethane resin is preferably made of a polyoxymethylene-copolymerized polycarbonate-based polyurethane resin. In the cloth material for sports equipment of the present invention, the base fabric preferably has a tear strength of 29.42 N (Newton) (3.0 kgf (kilogram)) or more. In the cloth material for sports equipment of the present invention, the base fabric preferably has a tensile strength of 294.1 N (30 kgf)/5 cm or more, an elongation of φ and 10% or more, and has 75. More than the wear resistance. In the cloth material for sports equipment of the present invention, the base fabric for woven fabric is composed of a plurality of polyester fiber main yarns A and a fineness of the main yarn A (unit: dtex (fabric) 2 to 5 times the fineness (unit: dtex) for the fabric reinforcement polyester fiber coarse-grained yarn B, the plurality of warp and weft, and the warp and weft In the respective yarn arrangement patterns, it is preferable that one of the two main yarns A disposed adjacent to each other in parallel with each other is disposed with one coarse-grained yarn B' every 2 to 50 pieces 200936839. In the fabric for a base fabric, a lattice-like reinforcing woven structure is formed. In the cloth material for sports equipment of the present invention, it is preferred that the polyester fiber has a cross section having a long axis along the long axis and 2 to 6 The circular shape is a flat uneven shape that is connected to each other in a partially overlapping manner. The cloth material for sports equipment of the present invention is excellent in tear strength and wear resistance, and can provide, in particular, a gliding parachute, a speedboat sailing, a kiteboard, etc. Using wind [Best preferred embodiment of the invention] The fabric material for sports equipment of the present invention comprises: a base fabric made of a woven fabric containing polyester fibers as a main component, and impregnated and adhered to the base fabric The polyoxyethylene copolymerized polyurethane resin layer on the woven fabric. The polyester fiber for the base fabric preferably contains: as a main component, terephthalic acid and/or naphthalene dicarboxylic acid. An aromatic dicarboxylic acid and a polyester formed as a glycol component containing ethylene glycol, 1,3-propanediol, and/or tetramethylglycol as a main component For the fiber polymer suitable for the present invention, polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, and polycalyxate B can be used. a glycol ester, etc. These polyester polymers can be used as a copolymerization component, and contain: isophthalic acid, adipic acid, oxybenzoic acid, diethylene glycol, propylene glycol, trimellitic acid, isoprene One or more kinds of alcohols, etc. The polyester fabric for the base fabric may contain Additives such as stabilizers, colorants, antistatic agents, etc. -8- 200936839 The fineness of the polyester fiber of the present invention (fineness) is preferably 15 to 300 dtex, more preferably 20 to 200 dtex'. To 170 dtex. If the fineness is 15 dtex or less, the strength of the fabric is inferior, and it may be difficult to exert the performance as a cloth material for sports equipment. On the other hand, if the fineness is 300 dtex or more, the cloth may be too heavy and may not be suitable. As the sports article, the single fiber fineness (hereinafter abbreviated as DPF) of the polyester fiber usable in the present invention is preferably 1.5 to 3.5 dtex. When the DPF is 1.5 dtex or less, the cloth material made from the fiber becomes It is too soft and may be easily broken. In addition, if the DPF is above 3.5 dtex, the fabric material made from the fiber may be excessively rough. The tensile strength and tensile elongation of the polyester fiber of the base fabric which can be used in the fabric material of the present invention are preferably 4.8 cN (centiNewton) / dtex or more and 10% or more, respectively, more preferably 5.0 respectively. Up to 15.0 cN/dtex and 10 to 30%. In general, in the case of polyester, if the tensile strength is increased, the tensile elongation tends to decrease. Even if the tensile strength of the polyester fiber is 4.8 cN/dtex or more, but the tensile elongation is less than 1%, the sports equipment made of the polyester fiber is used, for example, when the spinnaker is full of violent drums. When the wind is subjected to a large wind pressure, the appliance is immediately deformed (elongated) so that the performance of absorbing and utilizing the energy of the wind becomes insufficient and may be easily broken. In addition, even if the tensile elongation of the polyester fiber is 10% or more and the tensile strength is 4.8 cN/dtex or less, the fabric material containing the polyester fiber may be easily broken when subjected to a large wind pressure. The woven structure of the woven fabric of the base fabric which can be used in the cloth material of the present invention is not particularly limited, but is preferably a lattice-like reinforced woven structure. 200936839 The lattice-shaped reinforcing woven structure in the present invention is formed by the main sliver A and the coarse denier sliver B for fabric reinforcement, and the fineness of the coarse denier sliver B is the denier of the main sliver A. 2 to 5 times, and in the arrangement pattern of the warp yarns and the warp yarns of the woven fabric, one thick denier yarn B is arranged for every 2 to 50 of the main yarns A arranged in parallel with each other, thereby A lattice-like reinforcing woven structure is formed in the base fabric. Fig. 1 is a view showing an example of a woven structure of a fabric for a base fabric having a lattice-like woven structure of the cloth material of the present invention. In the first embodiment, in the yarn arrangement pattern of the warp yarn of the base fabric 10 of the fabric material of the present invention, 10 main yarns A and one coarse fine yarn B are used to form the winding yarn. The warp yarn aligning unit 1 is formed on its right side with a warp yarn arranging unit 2 formed by two main skeins A and one coarse skein skein B, and the warp arranging unit is arranged in an interactive winding manner. 1 and 2. Further, in the yarn arrangement pattern of the warp yarn, the yarn warp yarn aligning unit 3 is constituted by 8 main yarns A and one coarse fine yarn sliver B, and underneath, by a coarse-grain yarn The strips B constitute the winder weft array unit 4, and thus the warp yarn array units 3 and 4 are repeatedly arranged in an interactive manner. As shown in Fig. 1, since the warp yarn and the weft yarn are woven together, the main yarn A and the weft yarn formed by the majority of the main yarns A are arranged in a good regular manner for each predetermined number of the main yarns A. The coarse-grained sliver B thus constitutes a lattice-like reinforced woven structure. The above-mentioned coarse-grained sliver B may be a yarn obtained by buffing the above-mentioned main sliver A2 to five. Since the coarse-grained sliver B is arranged in a good regular manner in the warp direction and the weft direction of the fabric for the base fabric, the obtained fabric can function as a reinforcing material, and the deformation and cracking of the fabric can be displayed very large-10 - 200936839's resistance effect. If the yarn fineness of the coarse denier yarn B is less than twice the yarn fineness of the main sliver A, the reinforcing effect of the coarse denier sliver B may not be sufficient, and if the yarn denier is more than 5 times, The reinforcement effect of the coarse denier yarn B is increased, but the softness of the resulting fabric may be lowered. Further, when the number of the main slivers A arranged between the two coarse denier slivers B is two or less, the two coarse denier slivers B operate in the same manner as in the case of using such a blending yarn, so that The softness of the resulting fabric is lowered, and the wind resistance characteristics of the sports article made from the fabric material using the fabric as the base fabric may not be sufficient. Further, if the number of the main slivers A arranged between the two coarse denier slivers B is 50 or more, the interval between the two coarse denier slivers B becomes too wide, and these two thick ones are thick. The sliver of the sliver of the fineness of the slivers B is reduced, and the reinforcing effect of the fabric may not be sufficient. In the polyester fiber fabric of the present invention, the weight ratio of the coarse-denier gauze B to the full gauze is preferably 5 to 50%, and when the weight ratio is 5% or less, it may be by the coarse-grain gauze. The obtained fabric reinforcement effect will not be sufficient, and if the weight ratio is above 50%, the quality style and appearance of the obtained fabric may be poor. In the fabric material of the present invention, it is necessary to impregnate the resin with a base fabric made of a polyester fiber woven fabric to reduce the permeability. (If the sports article made from the fabric material of the present invention is to be full of drums) The wind and the wind are still not broken and can be used. The cloth itself needs to have moderate flexibility. Therefore, the resin to which the base fabric is applied must be a resin capable of maintaining such properties, and from the viewpoints of general versatility, economy, workability, etc., from the viewpoint of -11 to 200936839, a polyurethane resin is preferred. When a resin such as an acrylate resin or a polyvinyl chloride resin is used, although the gas permeability can be lowered, since the cloth material itself becomes hard, when the drum is full of wind and is subjected to a large wind pressure, the stretchability of the cloth itself changes. It is not appropriate to have a small and ruptured possibility. Examples of the polyurethane resin include an ether-based polyurethane resin, an ester-based polyurethane resin, and a carbonate-based polyurethane resin, but such polyamines are used. In the urethane resin, it was found that the fact that the Φ was not subjected to the water repellent treatment as the pretreatment before the resin processing, the fact that the good tear strength could not be obtained was obtained. The inventors have found that the polyurethane resin used in the present invention has been intensively examined, and it has been found that, for example, a polyaluminoxy-copolymerized polycarbonate-based polyurethane resin is used, and a polyamine group is imparted. The fact that the formate resin does not require pretreatment before it has a high tear strength. Furthermore, it has been found that the use of such a resin enhances the wear resistance. Polyoxymethylene-copolymerized polycarbonate-based polyurethane resin, which is used in the manufacture of a polycarbonate-based polyurethane resin to form a polyfluorene Φ compound, particularly with an organic polyfluorene. Oxygen is copolymerized to modify the person. The polycarbonate urethane resin component can be produced by a condensation reaction of a polycarbonate diol, an organic polyisocyanate, an alkylene glycol, and a diamine compound. The polycarbonate diol may, for example, be a 1,6-hexyl carbonate diol, a polyhexamethylene carbonate diol, a polytetramethylene carbonate diol or a poly octamethyl carbonate. Alcohol, polyheptylene carbonate diol, and the like. Among them, preferred is 1,6-hexyl carbonate diol. In terms of organic polyisocyanate, dicyclohexylmethane 4,4'. diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate 'bis(isocyanatomethyl)cyclohexane, from -12- 200936839 Acid or urethane ester acid cyanide cyanide isophthalate dimethyl keto benzene benzene ring extension bismuth 45- or .6-, 2, group 2, fatty acid ester acid acid cyanide Isocyanate isopropanoid dialkylcyanomethylisophenyl)-benzoquinone-Φ diφ phthalate, p-phenylene diisocyanate, tolidine diisocyanate, 1,5-naphthalene An aromatic diisocyanate such as diisocyanate or benzodimethyl diisocyanate. Among them, dicyclohexylmethane-4,4'-diisocyanate is preferred. The alkylene glycol may, for example, be 1,6-hexanediol, 1,4-butanediol or 1,5-pentanediol. Among them, preferred is 1,6-hexanediol. The diamine compound may, for example, be isophorone diamine, methyl phenyldiamine, tetramethylhexamethylenediamine or hexamethylenediamine, and among them, preferably different Fulcone diamine. When the condensation reaction is carried out, it is preferably a polyfluorene oxide compound having a molecular weight of from 1 000 to 12,000, preferably the above polyfluorene oxide compound capable of copolymerizing an organopolyoxyalkylene compound, having a terminal group on one side thereof having 2 Preferably, the -CH20 fluorenyl group (first alcohol residue) and the other terminal group are non-reactive. For example, those having the following chemical structure are preferably used. [Chemical 1] CH20H Me f Me,

The content of the polyoxymethylene copolymer component which can be used in the polyoxynoxy-polymerized polycarbonate-based polyurethane resin of the present invention is preferably the mass of the polycarbonate-based polyurethane resin component. It is 3 to 15% by mass, more preferably 5 to 10% by mass. Further, the molecular weight of the polyoxymethylene-copolymerized polycarbonate-based polyurethane resin is preferably from 30,000 to 500,000, more preferably from 50,000 to 350,000. In the polyoxyn copolyester carbonate urethane resin, if the content of the polyfluorene component is 3% by mass or less, the mechanical strength, particularly the abrasion resistance, of the resulting cloth material may be insufficient. Further, when the content is 15% by mass or more, the friction of the cloth material is lowered, and the slip between the cloths is liable to occur, resulting in a disadvantage of poor rollability. Further, when the molecular weight of the polyoxymethylene-copolymerized polycarbonate-based polyurethane resin is 30,000 or less, it may be difficult to sufficiently increase the tear strength, and if the molecular weight is 500,000 or more, it may be It has the disadvantage that the viscosity will increase and the impregnation will decrease. -14- 200936839 The quality of the base fabric in the cloth material of the present invention is such that the breaking strength and tear strength of the cloth material are maintained at an appropriate level, preferably 20 to 80 g/m2, more preferably 30. When the mass of the base fabric is below 20 g/m 2 , it may be difficult to obtain sufficient breaking strength, and it may be easily broken when subjected to high wind pressure. In addition, if the mass of the base fabric is 8 Og/m2 or more, the quality of the cloth will be too large, which is proportional to the mass of the fabric, so that the gliding performance of the resulting sports equipment is reduced and handled. It will also be inconvenient. In the cloth material of the present invention, the resin adhesion amount is preferably from 5 to 40 by mass based on the mass of the fabric. /. More preferably, it is from 1 3 to 35 mass%. Such as resin adhesion at 5 ° /. In the following, although the tear strength of the obtained cloth material can be improved, it is difficult to sufficiently reduce the gas permeability, so that the cloth material is full of wind and can utilize the wind pressure performance, for example, in a kiteboard In the case of a gliding parachute, the gliding performance is lowered to form a danger, and in the case of a spinnaker, the performance of effectively utilizing wind power is lowered. On the other hand, if the amount of the resin adhered is 40% by mass or more, the quality of the resulting cloth material is too large, so that the handling property is remarkably lowered. When the fabric material of the present invention is overweight, not only the gliding performance of the obtained sports equipment is lowered, but also the handling thereof is inconvenient, and for example, in the fabric for the spinnaker, due to the excessive cloth quality, Processing operability is significantly reduced. However, if the cloth is too light, the breaking strength and tear strength of the cloth material may not be sufficient. Accordingly, the fabric weight of the present invention is preferably from 20 to 100 g/m2, more preferably from 30 to 80 g/m2. If the fabric material of the present invention is not torn after repeated use, see -15-200936839, the tear strength needs to be 29.42N (3.0kgf) or more, preferably 39.2N (4.0kgf) to 98.0N ( 10.0kgf). If the tear strength is below 29.42N (3.0kgf), the sports equipment made from the cloth material, for example, in the gliding of the kiteboard, and the wind in the spinnaker The possibility of being torn when subjected to high wind pressure is increased. Further, the tensile strength and elongation of the cloth material of the present invention need to be 294.1 N (30 kgf) / 5 cm or more and 10% or more, respectively, preferably 400 to 700 N / 5 cm and 10 to 2 %, respectively. Generally, the breaking strength and elongation of the cloth material are changed by the fabric structure and the presence or absence of resin processing. For example, if the tensile strength is increased, the elongation may be lowered. Even if the tensile strength is above 294.1 N/5 cin, it is extended. When the rate is less than 10%, the toughness of the cloth material is insufficient. Therefore, when the sports equipment made of the cloth material is rushed to the wind and is subjected to high wind pressure, the risk of rupture suddenly Sex will increase. On the other hand, if the tensile strength is 291.4 N/5 cm or less, the exercise tool made from the cloth material is likely to be broken when subjected to high wind pressure due to its low tensile strength. Therefore, it is important to improve the tensile strength of 294.1 N/5cm or more and the elongation of 1% by weight or more, which is important for improving the crack resistance of the fabric material. Further, the air permeability of the cloth material of the present invention needs to be 1.0 ml/cm2/sec or less, preferably 0.1 ml/cm2/sec or less, more preferably 〇lml/cm2/sec or less. If the air permeability of the cloth material is above i.omi/cm" second, then the fabric material is full of wind and can be utilized for its wind pressure performance. For example, in the case of a kiteboard or a paraglider, gliding Sex-16-200936839 can be reduced to become dangerous, and in the case of the spinnaker, the performance of the effective use of wind power will be reduced. Furthermore, the abrasion resistance of the cloth material of the present invention is to avoid tearing during repeated use. Or, for rupture, it needs to be 75 times or more, more preferably 100 times or more. If the abrasion strength is less than 75 times, when it is used repeatedly, the sports equipment made from the cloth material is high when the drum is full of wind. When the wind pressure is applied, the risk of rupture from the worn point is increased. u In the manufacture of the cloth material of the present invention, the method of imparting the urethane resin to the base fabric is not In particular, it may be limited by a dipping method or a coating method. Both the dipping method and the coating method may be carried out. Regardless of the method, the polyurethane resin is required to sufficiently penetrate the base fabric. Internal and The immersion adhesion is applied to the obtained cloth material to give sufficient physical properties such as tensile strength, tear strength, abrasion resistance, and air permeability. Further, the polyurethane resin is impregnated with liquid to adhere to the base fabric, In this case, the liquid resin may be a water-based one or a non-aqueous one. g The cross-sectional shape of the polyester fiber contained in the woven fabric for a base fabric of the present invention is not particularly limited, and may have a generally circular shape or a polygonal shape, a quadrangular shape, a hexagonal shape, or the like, an elliptical shape, a flat shape, or a shape having two or more protrusions, and the like (an irregular shape). Among these irregular shapes, it is preferable to have a flat shape. The ratio of the maximum major axis length to the minimum minor axis length of the flat cross-sectional shape, that is, the flatness ratio, is preferably from 3 to 6, more preferably from 3 to 4. Among the flat cross-sectional shapes, the flat shape is Preferably, 2 to 6, more preferably 3 to 5 circular shapes are preferably arranged along the long axis of the cross section so as to partially overlap each other. -17- 200936839 2 to 6 hours, at In the flat shape, the one side of each long axis has 2 to 6 convex portions and 1 to 5 concave portions, and the convex portions and the concave portions are paired with the long axis, and symmetrical shapes are formed on both sides thereof. In such a flat concave-convex cross-sectional shape, if the number of circularly connected ones is 2 to 6, the difference between the cross-sectional area and the area of the circle whose major axis is the diameter is large, and the obtained fabric is On the other hand, if the number of the circularly connected ones is 7 or more, the melt warp yarn formability of the fiber having such a cross-sectional shape may be lowered, and the resulting uneven concave-convex shape may be obtained. In the above-mentioned flat and concave-convex cross-sectional shape, it is preferable that the diameters of the mutually connected circular shapes are equal to each other, and the convex portions and the concave portions which are symmetric with respect to the long axis are measured at right angles to the long axis. The width ratio Wi/W2 is preferably 1.1:3.0, more preferably 1_1:2.0. Further, when the diameters of the mutually connected circular shapes are different from each other, the maximum diameter thereof is preferably from 1 to 5 times, more preferably from 1 to 2 times the minimum diameter.
