Cloth material for sports equipment

The present invention relates to a cloth material for sports equipment. In particular, the present invention relates to a paraglider, a hang glider, a yacht sail, a spinnaker, a kiteboarding, and a stunt kite. Those who use the fabric materials used in the movement of wind.

In recent years, interest in sports has increased with the increase of the next day. Its connotation has also diversified, and recent leisure sports such as marine sports and sky sports are also very popular. As such products for sea sports and air sports, 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 cloth 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, in the case of such sportswear fabrics, not only the weather resistance but also the ripping strength or the abrasion resistance is required, and in the case of the resin-treated fabric, the tear strength is particularly required to be improved.

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 slippage of the fiber is improved and the tear strength can be improved, the adhesion mottle of the polyurethane resin is easily generated and is torn. The shortcomings of the very large variation in crack strength have been confirmed by subsequent research.

[Best Embodiment of the Invention]

The cloth material for sports equipment of the present invention comprises: a base fabric made of a fabric containing polyester fibers as a main component, and a polyoxymethylene copolymerized polyamine group which is impregnated and attached to the fabric for the base fabric. Acid resin layer. The polyester fiber for a base fabric is preferably an aromatic dicarboxylic acid containing terephthalic acid and/or naphthalene dicarboxylic acid as a main component, and ethylene glycol as a main component. , 3-propanediol, and/or tetramethylglycol as a polyester formed by the ethylene glycol component contained in the main component. For the fiber polymer suitable for the present invention, polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, and polyethylene naphthalate may be used. Alcohol esters and the like. These polyester polymers can be used as a copolymerization component and contain one type of isophthalic acid, adipic acid, oxybenzoic acid, diethylene glycol, propylene glycol, trimellitic acid, and isovaerythritol. the above.

The polyester fabric for a base fabric may contain additives such as a stabilizer, a colorant, and an antistatic agent.

The fineness (fineness) of the polyester fiber of the present invention is preferably from 15 to 300 dtex, more preferably from 20 to 200 dtex, still more preferably from 30 to 170 dtex. If the fineness is less than 15 dtex, 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 more than 300 dtex, the cloth weight is too heavy and may not be suitable as a sports apparatus. . 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. If the DPF is less than 1.5 dtex, the fabric material made from the fiber may be excessively soft and may be easily broken. Further, if the DPF is more than 3.5 dtex, the fabric material from the fiber may be excessive. 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 10%, 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. Further, even if the tensile elongation of the polyester fiber is 10% or more, but the tensile strength is less than 4.8 cN/dtex, 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 for the cloth material of the present invention is not particularly limited, but is preferably a lattice-like reinforced woven structure.

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 fineness 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 coarse 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 reinforcing woven structure of the cloth material of the present invention. In Fig. 1, in the yarn arrangement pattern of the warp yarns of the fabric 10 for a base fabric of the cloth material of the present invention, the warp yarns are arranged by 10 main yarns A and 1 coarse yarn sliver B. The unit 1 is formed on its right side with a twisted warp yarn aligning unit 2 formed by two main slivers A and one coarse denier sliver B, and the warp yarn aligning unit 1 is arranged in an interactive winding manner. 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 strip B constitutes 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 coarse-grained sliver B may be a yarn obtained by buffing the main sliver A2 to five. Since the coarse-grained sliver B is arranged in a 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 can exhibit a large resistance to deformation and cracking of the fabric. Resistance effect.

If the yarn fineness of the coarse denier yarn B is less than 2 times of the yarn fineness of the main sliver A, the reinforcing effect of the coarse denier sliver B may not be sufficient, and when 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. Moreover, if the number of the main slivers A arranged between the two coarse denier slivers B is less than two, the two coarse denier slivers B are operated in the same manner as when the blending yarns are used. The softness of the resulting woven fabric is lowered, and the wind pressure resistance of the sports article made of the woven 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 if the weight ratio is less than 5%, the grit may be used by the coarse gauze. The obtained fabric reinforcement effect may not be sufficient, and if the weight ratio is more than 50%, the quality style and appearance of the resulting fabric may be poor.

In the cloth 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 cloth material of the present invention is not ruptured under the wind and subjected to high wind pressure, the cloth itself needs to have moderate stretchability. Therefore, the resin to which the base fabric is applied must be a resin capable of maintaining such properties, and is preferably a polyurethane resin from the viewpoints of general versatility, economy, workability, and the like. When a resin such as an acrylate resin or a polyvinyl chloride resin is used, although the gas permeability can be lowered, the cloth material itself becomes hard, and 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 when such polyamines are used. The urethane resin was found to have a fact that good tear strength could not be obtained if the water repellent treatment as a pretreatment was not carried out before the resin processing. The present inventors have found out that the polyurethane resin used in the present invention has been intensively studied, and it has been found that, if a polyoxymethylene-copolymerized polycarbonate-based polyurethane resin is used, a polyamine group is imparted. The fact that the acid ester 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 polycarbonate-based polyurethane resin to form polyfluorene oxide compounds, especially organic polyoxyl Copolymerization is carried out 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 the case of organic polyisocyanates, dicyclohexylmethane 4,4'-diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, bis(isocyanatomethyl)cyclohexane, lysine ( Lysine) an aliphatic or alicyclic diisocyanate such as diisocyanate or 2,4-methylphenylene diisocyanate, 2,6-methylphenylene diisocyanate, 4,4'-diphenylmethane diisocyanate, An aromatic diisocyanate such as 2,4'-diphenylmethane isocyanate, p-phenylene diisocyanate, tolidine diisocyanate, 1,5-naphthalene 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 two terminal groups on one side thereof. The -CH ₂ OH group (first alcohol residue) and the other terminal group are preferably non-reactive. For example, those having the following chemical structure are preferably used.

[here, R represents an alkyl group, n represents an integer of 2 to 130, and Me represents a methyl group]

In the polyoxo compound of the above formula, there are two -CH ₂ OH groups (first alcohol residues) in the terminal group on the left side, and the terminal group -SiMe ₃ on the right side is a non-reactive group. In the polyoxyxene compound for copolymerization, when both terminal groups are the first alcohol residue, for example, the following polyoxo compound is used: The resulting tearing strength of the resulting cloth material may not be sufficient.

The polyfluorene-oxygenated polycarbonate-based polyurethane resin to be used in the present invention has a polyoxymethylene copolymer component content, preferably a 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 30,000 to 500,000, more preferably 50,000 to 350,000.

In the polyoxygenated copolymeric polycarbonate urethane resin, if the content of the polyfluorene component is less than 3% by mass, the mechanical strength, particularly the abrasion resistance, of the resulting cloth material may not be sufficient. Further, when the content is more than 15% by mass, the friction of the cloth material is lowered to easily cause slippage between the cloths, resulting in a disadvantage of poor rollability. Further, if the molecular weight of the polyoxymethylene-copolymerized polycarbonate-based polyurethane resin is less than 30,000, there may be a disadvantage that it is difficult to sufficiently increase the tear strength, and if the molecular weight exceeds 500,000, There may be disadvantages that the viscosity will increase and the impregnation will decrease.

The quality of the base fabric in the cloth material of the present invention is such that the breaking strength and the tear strength of the cloth material are maintained at an appropriate level, preferably 20 to 80 g/m ² , more preferably 30 to 75 g / m ² . If the mass of the base fabric is less than 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. Further, if the mass of the base fabric is more than 80 g/m ² , the amount of the resin is increased in proportion to the mass of the fabric, so that the quality of the cloth is too large, so that not only the gliding performance of the resulting sports equipment is lowered, but also the handling 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, more preferably from 10 to 35% by mass, based on the mass of the fabric. If the amount of resin adhesion is less than 5%, the tear strength of the obtained cloth material can be improved, but 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. Sufficient, for example, in the case of a kiteboard or a paraglider, the gliding performance is reduced and the danger is formed, and in the case of the spinnaker, the performance of effectively utilizing the wind is lowered. On the other hand, when the amount of the resin adhered exceeds 40% by mass, the quality of the resulting cloth material is too large, so that the handling workability 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 weight of the cloth of the present invention is preferably from 20 to 100 g/m ² , more preferably from 30 to 80 g/m ² .

If the cloth material of the present invention is not torn after repeated use See, the tear strength needs to be 29.42 N (3.0 kgf) or more, preferably 39.2 N (4.0 kgf) to 98.0 N (10.0 kgf). If the tear strength is less than 29.42N (3.0kgf), the sports equipment made from the fabric 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 25%, respectively. In general, the breaking strength and elongation of the cloth material are changed by the structure of the fabric 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 cm, if the elongation is less than 10%, the toughness of the cloth material is not sufficient, and therefore, when the sports equipment made from the cloth material is swollen, the wind is full. When subjected to high wind pressure, the risk of rupture will increase. On the other hand, if the tensile strength is less than 291.4 N/5 cm, the sports article made from the cloth material is easily broken when subjected to high wind pressure due to its low tensile strength. Therefore, it is important to simultaneously satisfy the tensile strength of 294.1 N/5 cm or more and the elongation of 18% or more in terms of improving the crack resistance of the cloth material.

Further, the air permeability of the cloth material of the present invention needs to be 1.0 ml/cm ² /sec or less, preferably 0.1 ml/cm ² /sec or less, more preferably 0.01 ml/cm ² /sec or less. If the air permeability of the cloth material exceeds 1.0 ml/cm ² /sec, 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 Performance will be reduced and become dangerous, and in the case of a spinnaker, the performance of the effective use of wind will be reduced.

Further, the abrasion resistance of the cloth material of the present invention needs to be 75 or more, more preferably 100 or more, in order to avoid tearing or cracking during repeated use. If the abrasion strength is less than 75 times, when the sports equipment made of the cloth material is subjected to high wind pressure when the drum is full of wind and is used repeatedly, the risk of rupture from the worn point will be suddenly broken. Increased.

In the production of the cloth material of the present invention, the method of imparting the polyurethane resin to the base fabric is not particularly limited, and a dipping method or a coating method may be employed. Both the dipping method and the coating method can be carried out. Regardless of the method used, it is required that the polyurethane resin can sufficiently penetrate into the interior of the base fabric and be immersed and adhered to give the obtained fabric material sufficient physical properties such as tensile strength, tear strength, abrasion resistance, Breathability.

Further, the polyurethane resin is impregnated and adhered to the base fabric in a liquid state. In this case, the liquid resin may be a water-based one or a non-aqueous one.

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 general circular shape or a polygonal shape such as a triangular shape, a square shape, a hexagonal shape, or the like, an elliptical shape, a flat shape, or An irregular (irregular) shape such as a shape of two or more protrusions. Preferably, the shape of the profiled shape has a flat shape. In this case, 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 3 to 6, more preferably 3 to 4. Among such flat cross-sectional shapes, the flattened shape is preferably 2 to 6, more preferably 3 to 5 circular, and it is preferable to have a flat uneven shape in which a part of the long axis of the cross section overlaps each other. When the number of the connected circles is 2 to 6, in such a flat shape, one side of each long axis has 2 to 6 convex portions and 1 to 5 concave portions, and such convex The portion and the recess are formed on the long axis and have a symmetrical shape 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 The air permeability will be moderately small. On the other hand, if the number of the mutually connected circles 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-shaped yarn may be easily stained. The problem.

In the above-mentioned flat concave-convex cross-sectional shape, it is preferable that the diameters of the mutually connected circular shapes are equal to each other, and the ratio of the width of the convex portion and the concave portion which are symmetric with respect to the long axis to the long axis at a right angle is W ₁ /W _{2 .} Good is 1.1:3.0, more preferably 1.1:2.0. Further, when the diameters of the mutually connected circular circles 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.
