Description

{FABRIC MATERIAL FOR SPORTS}

The present invention relates to a sports fabric material. More specifically, the present invention relates to a fabric material for use in wind-driven sports such as paragliders, hang gliders, yacht sails, spinnakers, kite boarding and sports kites.

With the recent increase in leisure, sports tend to become hobbies. The content has also been diversified, and leisure sports such as marine sports and sky sports have become more active in recent years. These marine sports and sky sports products include yacht sails, spinnakers, paragliders, hang gliders, kite boarding, etc., in which fiber fabric is used. Conventionally, nylon fibers have been used as sports fiber materials from the viewpoint of light weight and strength. In these sports fabric bags, since it is used outdoors for a long period of time, high weather resistance is required, and polyester fibers are used rather than nylon which has low weather resistance. Patent Document 1 proposes a fabric bag for sports equipment using polyester fibers, and Patent Document 2 proposes a fabric material for sports equipment in which a silicone resin and a polyurethane resin are attached to a lip stop structure fabric using polyester fibers .

[0004] However, these sports fabric fabric bags are required not only to improve weather resistance but also to improve tear strength and abrasion resistance, and in particular, in the case of fabrics subjected to resin processing, improvement of tear strength is particularly desired.

Patent Document 3 proposes a fabric obtained by performing water-repellent treatment as a pretreatment before urethane resin processing in order to improve tear strength. It has been confirmed in subsequent studies that the water-repellent pretreatment is performed before the urethane resin processing to improve the sliding of the fiber and improve the tear strength, but the unevenness of the adhesion of the urethane resin tends to occur and the tear strength varies greatly.

Carrying out the invention  Best form for

The fabric material for sports equipment of the present invention comprises bubbles made of a fabric containing a polyester fiber as a main component and a silicone copolymerized urethane resin layer impregnated in the fabric for airbags. Wherein the polyester fiber for batting comprises an aromatic dicarboxylic acid containing terephthalic acid and / or naphthalene dicarboxylic acid as a main component and an aromatic dicarboxylic acid containing as a glycol component ethylene glycol, 1,3-propanediol, and / or tetramethylene glycol as main components It is preferable that it is formed of a polyester having a glycol component. Polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, and polyethylene naphthalate are preferably used as the polymer for fibers in 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 bubble fabrics may contain additives such as stabilizers, colorants, and antistatic agents.

The fineness (linearity) of the polyester fiber of the present invention is preferably 15 to 300 dtex, more preferably 20 to 200 dtex, and still more preferably 30 to 170 dtex. When the fineness is less than 15 dtex, the strength as a fabric falls and the performance as a fabric material for sports equipment may not be exhibited. On the other hand, when the fineness is more than 300 dtex, the fabric weight becomes excessively heavy, . The single fiber fineness (hereinafter referred to as DPF) of the polyester fiber used 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 of this fiber becomes excessively flexible and liable to break. In addition, if the DPF is larger than 3.5 dtex, the fabric material made of this fiber is excessively crude Crude steel).

The tensile strength and the tensile elongation of the polyester fiber used in the foamed fabric of the fabric of the present invention are preferably 4.8 cN / dtex or more and 10% or more, and more preferably 5.0 to 15.0 cN / dtex and 10 to 30% desirable. Generally, when the tensile strength of the polyester fiber is increased, the tensile elongation tends to decrease. Even if the tensile strength of the polyester fiber is 4.8 cN / dtex or more, when the tensile elongation is less than 10%, a sports tool made using such a polyester fiber, for example, a spinnaker, When the wind pressure is applied, the wind tool is deformed (stretched), and the performance of absorbing the wind energy is insufficient, and the wind tool is liable to be ruptured. Even if 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 tends to break when subjected to abrupt wind pressure .

There is no particular limitation on the weave structure of the fabric used in the bubble of the fabric material of the present invention, but it is preferable that it has a lattice-like reinforcing weave structure.

The reinforcing staple structure of the lattice shape according to the present invention is composed of a sprinkling tank A and a fabric reinforcing staple fiber yarn B, wherein the fineness of the above-mentioned finishing yarn B is 2 to 5 times the fineness of the above- In addition, in the yarn arrangement pattern of the warp and weft of the fabric, one embroidery yarn B is arranged for every two to fifty yarns A arranged in parallel with each other, so that a lattice- .

Fig. 1 shows an example of a woven structure of a fabric for a base fabric having a lattice-like reinforcing woven structure of the fabric material of the present invention. 1, in the yarn arrangement pattern of warp yarns of the fabric 10 for embroidery fabric of the present invention, ten repeated yarn arrangements A and one yarn counting yarn B constitute a repeatedly oblique arrangement unit 1 , And a repeatingly inclined array unit (2) composed of two main arrays A and one tandem arches B is formed on the right side of the inclined array unit (1). These inclined array units (1) and (2) are arranged alternately and repeatedly. In the warp yarn arrangement pattern, the repeating warp arrangement unit 3 is constituted by eight casting tanks A and one warp yarn yarn B, and one weft yarn repeat yarn B is repeatedly formed therebelow, An array unit 4 is constituted, and the inclined array units 3 and 4 are arranged alternately and repeatedly. As shown in FIG. 1, since the warp yarns and the weft yarns are woven together, the warp yarns B are regularly arranged in every predetermined number of the main yarns A in the warp yarns and weft yarns composed of the plurality of warp yarns A, Reinforced woven structure is constituted.

The above taundo shoji B may be obtained by folding two to five of the above-mentioned shoji Ao. Such a stepped yarn B, by regularly embedding the warp knitted fabric in the warp direction and weft direction, acts as a reinforcing material for the resulting fabric, and can exhibit a large resistance effect against deformation and fracture of the fabric.

If the reinforcing effect of the embossed yarn B is insufficient and the reinforcing effect of the embossing yarn B is larger than 5 times, the reinforcing effect of the embossing yarn B is not sufficient But tends to lower the flexibility of the obtained fabric. When the number of the main yarns A arranged between the two yarns B is less than two, the two yarns B behave as in the case of using the yarns of the two yarns, and the flexibility of the fabric thus obtained is deteriorated , The resistance to wind pressure of a sports tool made of a foam material having the fabric as bubbles may become insufficient.

In addition, if the number of the main threads A arranged between the two end threads is greater than 50, the spacing between the two threads is excessive, so that the cohesiveness of the threads And the reinforcing effect on the fabric may be insufficient. In the polyester fiber fabric used in the present invention, it is preferable that the weight ratio of the finishing yarns to the whole yarns is 5 to 50%, and when it is less than 5%, the fabric reinforcing effect by the finishing yarns is insufficient, If it exceeds 50%, the feeling and appearance of the resultant fabric may be poor.

In the fabric material of the present invention, it is necessary to lower the air permeability by impregnating a bubble made of a polyester fiber fabric with a resin. In order to use the sports equipment made of the fabric material of the present invention without being ruptured even when it is inflated with wind and subjected to a large wind pressure, the stretchability appropriate for the fabric itself is required. Therefore, the resin to be imparted to the bubbles is required to be a resin capable of maintaining such properties, and is preferably a urethane resin from the viewpoints of versatility, economy, workability, and the like. Acrylic resin, or vinyl chloride resin, the air permeability can be lowered. However, since the foam material itself becomes hardened, when the air is inflated to inflate and a large wind pressure is applied, the elasticity of the fabric itself becomes small, Which is undesirable.

The urethane resin includes an ether-based urethane resin, an ester-based urethane resin, and a carbonate-based urethane resin. When these urethane resins are used, good tear strength can not be obtained unless a water-repellent treatment is performed as a pretreatment before resin processing . The present inventors have intensively studied the urethane resin used in the present invention. As a result, they found that the use of a silicone copolymerized polycarbonate-based urethane resin eliminates the need for pretreatment prior to the application of the urethane resin and has a high tear strength. Further, it has been found that the abrasion strength can be improved by using such a resin.

The silicone-copolymerized polycarbonate-based urethane resin is obtained by copolymerizing a silicone compound, particularly an organopolysiloxane, in the production of a polycarbonate-based urethane resin.

The polycarbonate urethane resin component can be produced by a condensation reaction of a polycarbonate diol, an organic polyisocyanate, an alkylenediol, and a 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. Of these, 1,6-hexyl carbonate diol is preferred. Examples of the organic polyisocyanate include aliphatic or alicyclic diisocyanates such as dicyclohexylmethane 4,4'-diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, bis (isocyanatomethyl) cyclohexane and lysine diisocyanate, and 2 , Tolylene diisocyanate, 2,6-tolylene diisocyanate, 4,4'-diphenylmethane diisocyanate, 2,4'-diphenylmethane diisocyanate, P-phenylenediisocyanate, tolylidine diisocyanate, 1,5 -Naphthalene diisocyanate, xylylene diisocyanate, and other aromatic diisocyanates. Among them, dicyclohexylmethane-4,4'-diisocyanate is preferable. Examples of the alkylene diol include 1,6-hexanediol, 1,4-butanediol, and 1,5-pentanediol. Among them, 1,6-hexanediol is preferable. Examples of the diamine compound include isophoronediamine, tolylene diamine, tetramethylhexamethylenediamine, hexamethylenediamine and the like, among which isophoronediamine is preferable.

The silicone compound capable of copolymerizing a silicone compound, preferably an organopolysiloxane compound, having a molecular weight of preferably 1000 to 12000 at the time of the condensation reaction has two terminal groups of -CH ₂ OH groups And a terminal group of the other terminal is preferably non-reactive. For example, it is preferable to use one having the following chemical structure.

[Chemical Formula 1]

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

In the silicone compound of the above formula, two -CH ₂ OH groups (primary alcohol residues) in the left terminal group and two terminal -SiMe ₃ Is a non-reactive group. When both end groups of the silicone compound for copolymerization are primary alcohol residues, for example, the following silicone compound:

(2)

, The tear strength of the obtained fabric material sometimes becomes insufficient.

In the silicone-copolymerized polycarbonate-based polyurethane resin used in the present invention, the content of the silicone copolymerization component is preferably 3 to 15 mass%, more preferably 5 to 10 mass%, based on the mass of the polycarbonate-based polyurethane resin component More preferable. The molecular weight of the silicone-copolymerized polycarbonate-based polyurethane resin is preferably from 30,000 to 500,000, more preferably from 50,000 to 350,000.

In the silicone-copolymerized polycarbonate polyurethane resin, when the content of the silicone component is less than 3% by mass, the mechanical strength, particularly the abrasion strength, of the resultant foaming material may be insufficient, and if it exceeds 15% by mass, The friction is lowered and slippage easily occurs between the fabrics, resulting in a problem that the winding-up property is deteriorated. When the molecular weight of the silicone copolymerized polycarbonate-based polyurethane resin is less than 30,000, there is a problem that the tear strength can not be sufficiently improved, and when it exceeds 500,000, the viscosity increases and the impregnability decreases In some cases.

The mass of the base fabric in the fabric of the present invention is preferably 20 to 80 g / m 2, more preferably 30 to 75 g / m 2, in order to maintain the breaking strength and tear strength of the fabric material at a proper level. When the mass of the bubble fabric is less than 20 g / m 2, a sufficient breaking strength can not be obtained, and it is likely to be ruptured when the wind pressure is high. If it exceeds 80 g / m 2, the adhesion amount of the resin increases to some extent in relation to the fabric mass, so that the mass of the fabric becomes excessively large, and the glide performance of the obtained sports tool is deteriorated, It becomes.

In the fabric material of the present invention, the amount of resin adhered 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 adhesion amount of the resin is less than 5%, the tear strength of the obtained fabric material is improved, but the air permeability can not be sufficiently lowered, and the performance of using the fabric material to inflate and utilize the wind pressure becomes insufficient, In the case of a boarding or paraglider, the gliding performance is deteriorated and becomes dangerous, and in the case of the spinnaker, the performance of efficiently using the wind is lowered. On the other hand, when the amount of resin adhered exceeds 40% by mass, the mass of the obtained fabric material becomes excessive, and handling operability thereof is remarkably lowered, which is not preferable.

When the mass of the fabric material of the present invention is excessively large, not only the glide performance of the obtained sports equipment is lowered but also it is inconvenient in portable transportation. In addition, for example, in a spinnaker fabric material, The handling operability thereof is remarkably lowered. However, when the warp-off mass becomes too small, the breaking strength and the tear strength of the warp-knit 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.

The tear strength of the fabric of the present invention is required to be 29.42 N (3.0 kgf) or more, preferably 39.2 N (4.0 kgf) to 98.0 N (10.0 kgf) in order to prevent tearing of the fabric material after repeated use. If the tear strength is less than 29.42 N (3.0 kgf), there is a possibility that the sports equipment made of the above-mentioned fabric material, for example, during gliding in kite boarding, or in spinnaker, .

In the present invention, the tensile strength and elongation of the fabric material should be 294.1 N (30 kgf) / 5 cm or more and 10% or more, preferably 400 to 700 N / 5 cm and 10 to 25% to be. Generally, the fracture toughness of the fabric material changes depending on the fabric structure and the presence or absence of resin processing. However, when the tensile strength is increased, the elongation tendency tends to be lowered. 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 becomes insufficient, and therefore, when a sports tool made of a fabric material suddenly winds up, The risk of becoming higher. On the other hand, when the tensile strength is less than 291.4 N / 5 cm, the sports equipment made of the above-mentioned fabric material tends to be ruptured when it is subjected to a high wind pressure due to its low tensile strength. Therefore, it is important to satisfy both the tensile strength of 294.1 N / 5 cm or more and the tensile strength of 10% or more at the same time to improve the frictional resistance of the fabric material.

The air permeability of the fabric material in the present invention should be 1.0 ml / cm2 / sec or less, preferably 0.1 ml / cm2 / sec or less, and more preferably 0.01 ml / cm2 / sec or less. When the air permeability of the fabric material exceeds 1.0 ml / cm 2 / sec, the air of the fabric material is inflated and the performance capable of utilizing the wind pressure becomes insufficient. For example, in the case of kite boarding or paragliding, The performance deteriorates and becomes dangerous, and in the case of the spinnaker, the performance for efficiently using the wind is deteriorated.

Further, the abrasion strength of the fabric material of the present invention is required to be 75 times or more, more preferably 100 times or more, in order to avoid tearing or tearing in repeated use. If the abrasion strength is less than 75 times, the repetitive use of a sports article made of bobbing material suddenly winds up and swells, resulting in a high wind pressure, which increases the risk of rupture at a time from the worn point.

In the production of the fabric material of the present invention, the method of applying the urethane resin to the bubble fabric is not particularly limited, but an impregnation method or a coating method is employed. In addition, both the impregnation method and the coating method may be carried out. In any case, it is necessary to sufficiently impregnate the urethane resin into the inside of the bubble cloth, so as to impregnate the foam material with sufficient physical properties, for example, tensile strength, tear strength, abrasion strength and air permeability.

In addition, the urethane resin is impregnated in a bubble cloth in a liquid phase. 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 embroidery of the present invention is not particularly limited, and may be a general circular shape or a polygonal shape such as a triangular shape, a square shape, a hexagonal shape, an elliptical shape, (Irregular) shape such as a shape having an irregular shape. Of these deformed shapes, those having a flat shape are preferable, and in this case, the ratio of the maximum major axis length to the minimum minor axis length of the flat cross-sectional shape is preferably from 3 to 6, more preferably from 3 to 4 . Among such flat cross-sectional shapes, it is preferable that the circular shape having a flat shape of preferably 2 to 6, more preferably 3 to 5, has a flat concavo-convex shape connected to overlap each other along the long axis of the cross section. In the case where the number of connected circular shapes is 2 to 6, in such a flat shape, it has convex portions of 2 to 6 per side of the major axis and concave portions of 1 to 5, and these convex portions and concave portions are formed on both sides It is symmetrical. When the number of the circular shapes connected to each other in such a flat concavo-convex cross-sectional shape is 2 to 6, the difference in area between the cross-sectional area and the circle having the major axis as the diameter becomes large, and the air permeability of the obtained fabric is appropriately reduced. On the other hand, when the number of the circles to be connected to each other is 7 or more, the melt-warp formability of the fibers having such a cross-sectional shape is lowered, and a problem that staining irregularity tends to occur in the obtained flat concavo-convex cross- have.

In the flat concavo-convex cross-sectional shape, the diameters of the circles connected to each other are preferably the same, and the ratio of the widths measured at right angles to the long axis of the convex portion and the concave portion symmetrical with respect to the long axis (W ₁ / W ₂ ) Is preferably 1.1: 3.0, more preferably 1.1: 2.0. When the diameters of the circles connected to each other are different from each other, the maximum diameter is preferably 1 to 5 times, more preferably 1 to 2 times the minimum diameter.
