The fabric material for sports equipment of the present invention includes a base fabric made of a woven fabric containing polyester fiber as a main component, and a silicone copolymer urethane resin layer impregnated and adhered to the woven fabric for base fabric. The polyester fiber for the base fabric is mainly composed of aromatic dicarboxylic acid containing terephthalic acid and / or naphthalenedicarboxylic acid as a main component and ethylene glycol, 1,3-propanediol and / or telelamethylene glycol as a glycol component. It is preferably formed from a polyester as a glycol component contained as a component. Polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyethylene naphthalate, etc. are used as the preferred fiber polymer for the present invention. These polyester polymers may contain at least one of isophthalic acid, adipic acid, oxobenzoic acid, diethylene glycol, propylene glycol, trimellitic acid, pentaerythritol and the like as a copolymerization component.
The polyester fabric for the base fabric may contain additives such as a stabilizer, a colorant, and an antistatic agent.

  The fineness (line safety) of the polyester fiber of the present invention is preferably 15 to 300 dtex, more preferably 20 to 200 dtex, still more preferably 30 to 170 dtex. When the fineness is less than 15 dtex, the strength as a woven fabric is inferior, and the performance as a fabric material for sports equipment may not be exhibited. On the other hand, when the fineness exceeds 300 dtex, the weight of the fabric becomes too heavy and the sports equipment May be inappropriate. The single fiber fineness (hereinafter referred to as DPF) of the polyester fiber used in the present invention is desirably 1.5 to 3.5 dtex. If the DPF is less than 1.5 dtex, the fabric material made from this fiber may become excessively soft and easily break, and if the DPF is greater than 3.5 dtex, Fabric materials made from fibers can become too rough and stiff.

  The tensile strength and tensile elongation of the polyester fiber used for the base fabric of the fabric material of the present invention are preferably 4.8 cN / dtex or more and 10% or more, respectively, and 5.0 to 15.0 cN, respectively. More preferably, it is / dtex and 10 to 30%. In general, when the tensile strength of polyester fibers is increased, the tensile elongation tends to decrease. Even if the tensile strength of the polyester fiber is 4.8 cN / dtex or more, if the tensile elongation is less than 10%, a sports equipment such as a spinnaker manufactured using such a polyester fiber is rapidly When a wind is applied and a large wind pressure is applied, the tool immediately deforms (extends), and the ability to absorb and use the energy of the wind becomes insufficient and may easily burst. Further, even when the tensile elongation of the polyester fiber is 10% or more, when the tensile strength is less than 4.8 cN / dtex, the fabric material containing the polyester fiber was subjected to a rapid wind pressure. Sometimes it is easy to break.

Although there is no particular limitation on the woven structure of the woven fabric used for the base fabric of the fabric material of the present invention, it preferably has a lattice-shaped reinforcing woven structure.
The lattice-shaped reinforcing woven structure in the present invention includes a main yarn A and a thick fine yarn B for reinforcing fabric, and the fineness of the thick fine yarn B is 2 to 2 of the fineness of the main yarn A. 5 times, and in each yarn arrangement pattern of warp and warp of the woven fabric, one large fine yarn B is arranged for every 2 to 50 main yarns arranged parallel to each other. Thereby, a grid-like reinforcing woven structure is formed on the base fabric.

  FIG. 1 shows an example of a woven structure of a fabric for a base fabric having a lattice-shaped reinforcing woven structure of the fabric material of the present invention. In FIG. 1, in the warp yarn arrangement pattern of the base fabric fabric 10 of the fabric material of the present invention, repeated warp arrangements with ten main yarns A and one large fine yarn B A unit 1 is formed, and a repetitive warp array unit 2 composed of two main yarns A and one large fine yarn B is formed on the right side of the unit 1, and the warp array units 1 and 2 are alternately arranged. It is arranged repeatedly. In the warp yarn arrangement pattern, the eight main yarns A and one large fine yarn B1 are repeated to constitute the warp arrangement unit 3, and below that, one thick fine yarn. The weft arrangement unit 4 is constituted by repeating with the strip B, and the warp arrangement units 3 and 4 are arranged alternately and repeatedly. As shown in FIG. 1, since the warp and the weft are woven together, the warp and the weft consisting of a large number of main yarns A include a thick yarn B for each predetermined number of main yarns A. Are regularly arranged, thereby forming a lattice-like reinforcing woven structure.

  The thick fine yarn B may be a combination of 2 to 5 main yarns A. Such a high-definition yarn B acts as a reinforcing material on the resulting fabric by regular weaving in the warp method and weft direction of the fabric for the base fabric, and is great for deformation and breakage of the fabric. A resistance effect can be shown.

  When the yarn fineness of the thick fine yarn B is less than twice the yarn fineness of the main yarn A, the reinforcing effect of the thick fine yarn B becomes insufficient, and when it becomes larger than five times. The reinforcing effect of the thick fine yarn B is enhanced, but the flexibility of the resulting fabric tends to be lowered. Further, when the number of main yarns A arranged between the two thick fine yarns B is less than two, when the two thick fine yarns B use their combined yarns And thus the flexibility of the resulting fabric may be reduced, and the wind resistance characteristics of sports equipment made from fabric materials based on this fabric may be insufficient.

  In addition, when the number of main yarns A arranged between the two thick fine yarns B is more than 50, the interval between the two thick fine yarns B becomes excessive, so that these two The cooperation between the yarns of the thick fine yarn B may be reduced, and the reinforcing effect on the fabric may be insufficient. In the polyester fiber fabric used in the present invention, the weight ratio of the thick yarn B to the total yarn is preferably 5 to 50%, and when it is less than 5%, the fabric by the thick yarn If the reinforcing effect is insufficient and if it exceeds 50%, the texture and appearance of the resulting fabric may be poor.

  In the fabric material of the present invention, it is necessary to impregnate and adhere a resin to a base fabric made of a polyester fiber fabric to reduce the air permeability. In order for the sports equipment made from the fabric material of the present invention to be used without bursting even if it receives wind and receives a large wind pressure, the fabric itself needs to have appropriate stretchability. Therefore, the resin applied to the base fabric needs to be a resin that can maintain such properties, and is preferably a urethane resin from the viewpoints of versatility, economy, workability, and the like. When resin such as acrylic resin or vinyl chloride resin is used, the breathability can be lowered, but the fabric material itself becomes hard, so when it receives wind and large wind pressure, the stretchability of the fabric itself becomes small and bursts. Because there is a possibility, it is not preferable.

  Urethane resins include ether-based urethane resins, ester-based urethane resins, and carbonate-based urethane resins. When these urethane resins are used, good tearing is required unless water-repellent treatment is performed as a pretreatment prior to resin processing. It has been found that strength cannot be obtained. As a result of earnestly examining the urethane resin used in the present invention, the present inventor has no need for pretreatment before applying the urethane resin and has high tear strength by using the silicon copolymer polycarbonate-based urethane resin. I found it. Furthermore, it has been found that the wear strength can be improved by using such a resin.

〔但し、Ｒはアルキル基を表し、ｎは２〜１３０の整数を表し、Ｍｅはメチル基を表す〕The silicone-copolymerized polycarbonate-based urethane resin is obtained by copolymerizing a silicone compound, particularly organopolysiloxane, in the production of a polycarbonate-based urethane resin.
The polycarbonate urethane resin component can be produced by a condensation reaction of polycarbonate diol, organic polyisocyanate, alkylene diol, and diamine compound. Examples of the polycarbonate diol include 1,6-hexyl carbonate diol, polyhexamethylene carbonate diol, polytetramethylene carbonate diol, polypentamethylene carbonate diol, polyheptamethylene carbonate diol and the like. Among these, 1,6-hexyl carbonate diol is preferable. Examples of organic polyisocyanates include aliphatic or alicyclic diisocyanates such as dicyclohexylmethane 4,4′-diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, bis (isocyanatomethyl) cyclohexane, lysine diisocyanate, and 2,4-tolylene diisocyanate. Aromatic diisocyanates such as isocyanate, 2,6-tolylene diisocyanate, 4,4'-diphenylmethane diisocyanate, 2,4'-diphenylmethane diisocyanate, P-phenylene diisocyanate, tolidine diisocyanate, 1,5-naphthalene diisocyanate, xylylene diisocyanate Is mentioned. Of these, dicyclohexylmethane-4,4′-diisocyanate is preferable. Examples of the alkylene diol include 1,6-hexanediol, 1,4-butanediol, 1,5-bentanediol, and the like. Of these, 1,6-hexanediol is preferable. Examples of the diamine compound include ifolone diamine, tolylenediamine, tetramethylhexamethylene diamine, hexamethylene diamine, etc. Among them, ifolone diamine is preferable.
In the condensation reaction, the silicone compound having a molecular weight of preferably 1000 to 12000 and preferably capable of copolymerizing an organopolysiloxane compound has one terminal group having two —CH ₂ OH groups. (Primary alcohol residue) and the other terminal group is preferably non-reactive, for example, it is preferable to use one having the following chemical structure.

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

を用いると、得られる布帛材料の引裂強さが不十分になることがある。In the silicone compound of the above formula, the left terminal group has two —CH ₂ OH groups (primary alcohol residues), and the right terminal group —SiMe ₃ is a non-reactive group. In the silicone compound for use, when both terminal groups are primary alcohol residues, for example, the following silicone compound:

When used, the resulting fabric material may have insufficient tear strength.

In the silicone copolymer polycarbonate polyurethane resin used in the present invention, the content of the silicone copolymer component is preferably 3 to 15% by mass with respect to the polycarbonate polyurethane resin component mass, and is 5 to 10% by mass. More preferably it is. The molecular weight of the silicone copolymer polycarbonate-based polyurethane resin is preferably 30,000 to 500,000, and more preferably 50,000 to 350,000.
In the silicone copolymer polycarbonate polyurethane resin, if the content of the silicone component is less than 3% by mass, the mechanical strength, particularly the wear strength, of the resulting fabric material may be insufficient. If it exceeds mass%, the friction of the fabric material becomes low and slippage tends to occur between the fabrics, which may cause inconvenience that the winding property is deteriorated. Moreover, when the molecular weight of the silicone copolymer polycarbonate-based polyurethane resin is less than 30,000, there is a problem that the tear strength cannot be sufficiently improved. When the molecular weight exceeds 500,000, the viscosity increases and the impregnation property decreases. May cause inconvenience.

The mass of the base fabric in the fabric material of the present invention is preferably ²⁰ to 80 g / m ² , and more preferably 30 to 75 g in order to simply maintain the appropriate breaking strength and tear strength of the fabric material. / M ² . When the mass of the base fabric is less than 20 g / m ² , sufficient breaking strength cannot be obtained, and when it receives a high wind pressure, it tends to burst. Also, if it exceeds 80, the amount of resin attached increases to some extent in proportion to the mass of the fabric, so that the mass of the fabric becomes excessive, and not only the glide performance of the resulting sports equipment is lowered but also inconvenient to carry. It becomes.

  In the fabric material of the present invention, the resin adhesion amount is preferably 5 to 40% by mass, and more preferably 10 to 35% by mass with respect to the mass of the fabric. When the resin adhesion amount is less than 5%, the tear strength of the resulting fabric material is improved, but the air permeability cannot be sufficiently lowered, and the performance of using the wind pressure of the fabric material and utilizing the wind pressure is not satisfactory. For example, in the case of kite boarding or paraglider, the glide performance is lowered and dangerous, and in the case of a spinnaker, the performance of efficiently using wind is reduced. On the other hand, when the resin adhesion amount exceeds 40% by mass, the mass of the obtained fabric material becomes excessive, and the handling operability is remarkably lowered.

When the mass of the fabric material of the present invention is excessive, not only the glide performance of the resulting sports equipment is lowered, but also inconvenient to carry. For example, in the fabric material for spinnaker, the fabric mass is excessive. As a result, the handling operability is significantly reduced. However, when the fabric mass is too small, the breaking strength and tear strength of the fabric material are insufficient. Therefore, the fabric weight of the present invention is preferably ^{20 to} 100 g / m ² , more preferably 30 to 80 g / m ² .

  In order that the fabric material of the present invention is not torn even after repeated use, its 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 29.42 N (3.0 kgf), sports equipment made from the fabric material, such as kite boarding, during gliding, or spinnaker, is subjected to high wind pressure due to wind. The chance of tearing increases.

  Further, the tensile strength and elongation of the fabric material of the present invention are required 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 respectively. ~ 25%. In general, the breaking strength / elongation of a fabric material varies depending on the fabric structure and the presence / absence of resin processing, but when the tensile strength is increased, the elongation tends to decrease. Even if the tensile strength is 294.1 N / 5 cm or more, if the elongation is less than 10%, the toughness of the fabric material becomes insufficient, and therefore, sports equipment made from the fabric material suddenly There is a high risk that the wind will burst and burst at once when subjected to high wind pressure. On the other hand, when the tensile strength is less than 291.4 N / 5 cm, the sports equipment made from the fabric material tends to burst when subjected to high wind pressure due to its low tensile strength. Therefore, satisfying both the properties of a tensile strength of 294.1 N / 5 cm or more and an elongation of 10% or more at the same time is important for improving the burst resistance of the fabric material.

Further air permeability of the fabric material of the present invention is required to be not more than 1.0 ml / cm ² / sec, preferably 0.1m1 / cm ² / sec or less, more preferably 0.01m1 / cm ² / Less than a second. When the air permeability of the fabric material exceeds 1.0 ml / cm ² / sec, the performance of the fabric material is insufficient and the wind pressure can be used. For example, in the case of kite boarding or paraglider, glide performance As a spinnaker, the performance of efficiently using wind is reduced.

  Furthermore, the abrasion strength of the fabric material of the present invention needs to be 75 times or more in order to avoid tearing or rupture in repeated use, and more preferably 100 times or more. If the wear strength is less than 75 times, when sports equipment made from fabric material suddenly winds up and receives high wind pressure during repeated use, there is a higher risk of bursting from the worn area at a stretch. It is.

In the production of the fabric material of the present invention, the method for applying the urethane resin to the base fabric is not particularly limited, but an impregnation method or a coating method is employed. Moreover, you may perform both the impregnation method and the coating method. In any case, the urethane resin sufficiently penetrates and adheres to the inside of the base fabric, and imparts sufficient physical properties to the resulting fabric material, such as tensile strength, tear strength, abrasion strength, and air permeability. is required.
The urethane resin is liquid and impregnated on the base fabric. At this time, the liquid resin may be aqueous or non-aqueous.

  The cross-sectional shape of the polyester fiber contained in the fabric for base fabric of the present invention is not particularly limited, and is usually a polygonal shape such as a circular shape, a triangular shape, a quadrangular shape, a hexagonal shape, an elliptical shape, a flat shape, or a formula of 2 It can have an irregular (irregular) shape such as a shape having more than one protrusion. Of these irregular shapes, it is preferable to have a flat shape. In this case, the ratio of the maximum long axis length to the minimum short axis length of the flat cross-sectional shape, that is, the flatness is preferably 3 to 6. More preferably, it is ~ 4. Among such flat cross-sectional shapes, the flat shape is preferably 2-6, more preferably 3-5, with a part overlapping each other along the long axis of the cross-section. It is preferable that it is a connected flat uneven shape. When the number of connected circles is 2 to 6, such a flat shape has 2 to 6 protrusions and 1 to 5 recesses on one side of the long axis. The portion and the recess are symmetrical on both sides with respect to the long axis. When the number of circles connected to each other in such a flat uneven cross-sectional shape is 2 to 6, the difference between the cross-sectional area and the area of the circle whose diameter is the major axis is large, and the ventilation of the resulting fabric The degree is moderately reduced. On the other hand, when the number of circles connected to each other is 7 or more, the melt warp formability of the fiber having such a cross-sectional shape is lowered, and dyeing spots are generated on the obtained flat concavo-convex cut yarn. May cause problems.

In the above-described flat concavo-convex cross-sectional shape, it is preferable that the diameters of the circles connected to each other are equal to each other, and the ratio of the width measured at right angles to the long axis of the convex and concave portions that are symmetrical to each other about the long axis W ₁ / W ₂ is preferably 1.1: 3.0, and more preferably 1.1: 2.0. Further, when the diameters of the circular shapes connected to each other are different from each other, the maximum diameter is preferably 1 to 5 times the minimum diameter, and preferably 1 to 2.

The invention is illustrated in more detail by the following examples. The physical properties described in the examples were measured by the following methods.
(1) Tear strength Measured by JIS L 1096-1999 8.15.1 A-1 method (single tongue method). However, the tensile speed was 10 cm / min.
