The specific embodiment
Sports requsites of the present invention contains the urethane resin layer of base cloth and organosilicon copolymerization with cloth and silk material; Said base cloth constitutes by containing the woven fabric of polyester fiber as main component, and the urethane resin layer of said organosilicon copolymerization floods attached to this base cloth with on the woven fabric.Preferred above-mentioned base cloth is formed by polyester with polyester fiber; Said polyester be contain terephthalic acid (TPA) and/or naphthalenedicarboxylic acid as the aromatic dicarboxylic acid of main component with contain ethylene glycol, 1, ammediol and/or tetramethylene glycol obtain as diol component as the diol component of main component.Use polymer as preferred fiber among the present invention, use PETG, polybutylene terephthalate (PBT), polytrimethylene terephthalate and PEN etc.These polyester polymers also can contain M-phthalic acid, adipic acid, oxo benzoic acid, diethylene glycol (DEG), propylene glycol, trimellitic acid, pentaerythrite etc. more than a kind as copolymer composition.
Above-mentioned base cloth woven fabric is with containing additives such as stabilizing agent, colouring agent, antistatic additive in the polyester woven fabric.
The fineness of preferred polyester fiber of the present invention (line density) is 15~300dtex, and more preferably 20~200dtex further is preferably 30~170dtex.When fineness deficiency 15dtex, as the intensity difference of woven fabric, can't bring into play as the performance of sports requsites with cloth and silk material, on the other hand, when fineness surpassed 300dtex, cloth and silk weight became overweight, had the situation that is not suitable for sports requsites.The filament fineness (below be called DPF) that is preferred for polyester fiber of the present invention is 1.5~3.5dtex.When the not enough 1.5dtex of DPF, the cloth and silk material of being made by this fiber produces and becomes too soft and the unfavorable condition of fracture easily, in addition, if the situation that DPF greater than 3.5dtex, then exists the cloth and silk material made by this fiber to become too thick and stiff.
It is above with more than 10% that the TENSILE STRENGTH of the employed polyester fiber of base cloth woven fabric of cloth and silk material of the present invention and tensile elongation preferably are respectively 4.8cN/dtex, more preferably is respectively 5.0~15.0cN/dtex and 10~30%.Usually, for polyester fiber, if its TENSILE STRENGTH increases, then tensile elongation has the tendency of reduction.Even the TENSILE STRENGTH of polyester fiber is more than the 4.8cN/dtex; When its tensile elongation less than 10%; Use for example spinnaker of sports requsites that such polyester fiber makes, at the full wind of drum suddenly, when receiving big blast, exist this apparatus to be out of shape (elongation) immediately; Absorb the energy of wind and the performance that is used and become insufficient, the situation of fracture easily becomes.In addition, even the tensile elongation of polyester fiber is more than 10%, when its TENSILE STRENGTH deficiency 4.8cN/dtex, there is the situation of fracture easily in the cloth and silk material that contains this polyester fiber when receiving rapid blast.
The woven of the employed woven fabric of base cloth of cloth and silk material of the present invention organized not restriction especially, but preferably has the woven tissue that clathrate strengthens machine-knitted structure.
Above-mentioned clathrate among the present invention strengthens machine-knitted structure; Strengthened by main sliver A and woven fabric and to constitute with fineness degree sliver B, the fineness of above-mentioned fineness degree sliver B is 2~5 times of fineness of above-mentioned main sliver A, and in the sliver Pareto diagram separately of the warp thread of woven fabric and weft yarn; In per 20~50 main sliver A that are arranged in parallel with each other; Be arranged with 1 fineness degree sliver B, thus, on the base cloth woven fabric, form clathrate and strengthen machine-knitted structure.
Fig. 1 is that the clathrate that has of expression cloth and silk material of the present invention strengthens the figure of the base cloth of woven tissue with an example of the woven tissue of woven fabric.In Fig. 1; In the sliver Pareto diagram of base cloth with the warp thread of woven fabric 10 of cloth and silk material of the present invention; Constitute the repetition warp thread through 10 main sliver A and 1 fineness degree sliver B and arrange unit 1; Be adjacent to form by 2 main sliver A and 1 repetition warp thread arrangement unit 2 that fineness degree sliver B constitutes on its right, this warp thread is arranged alternately repeated arrangement of unit 1 and 2.In addition; In the sliver Pareto diagram of weft yarn; Constitute repetition weft yarn arrangement unit 3 through 8 main sliver A and 1 fineness degree sliver B, thereunder constitute repetition weft yarn arrangement unit 4 through 2 main sliver A and 1 fineness degree sliver B, above-mentioned weft yarn arrangement unit 3 and 4 is repeated arrangement alternately.As shown in Figure 1, because therefore warp thread and weft yarn weave in warp thread that comprises many main sliver A and weft yarn, dispose fineness degree sliver B regularly in the main sliver A of each regulation radical, thus, constitute the woven tissue of cancellate enhancing.
Above-mentioned fineness degree sliver B closes the sliver that yarn forms with 2~5 above-mentioned main sliver A.Through such fineness degree sliver B is inweaved on the warp thread direction of woven fabric and weft direction at base cloth regularly, can play a role as reinforcing material for the woven fabric that obtains, can demonstrate big opposing effect for the distortion and the fracture of woven fabric.
When 2 times of the yarn fineness of the not enough main sliver A of the yarn fineness of above-mentioned fineness degree sliver B; The reinforced effects of this fineness degree sliver B is insufficient, in addition, if greater than 5 times; Though then the reinforced effects of this fineness degree sliver B improves, the flexibility of resulting woven fabric has the tendency of reduction.In addition; During 2 of the number deficiency of the main sliver A that between 2 fineness degree sliver B, arranges; Above-mentioned 2 fineness degree sliver B play and the identical effect of the situation of closing yarn of using them; The flexibility of the woven fabric that obtains is reduced, have the anti-blast characteristic of utilizing the sports requsites of making as the cloth and silk material of base cloth with this woven fabric inadequate situation that becomes.
In addition; If the number of the main sliver A that between 2 fineness degree sliver B, arranges is more than 50; Then the interval of 2 fineness degree sliver B becomes excessive, so mutual concertedness reduces between the sliver of these 2 fineness degree sliver B, has its reinforced effects to woven fabric inadequate situation that becomes.In polyester fiber woven fabric used in the present invention; Preferred fineness degree sliver B is 5~50% with respect to the weight ratio of whole slivers; When its less than 5%, insufficient by the woven fabric reinforced effects that the fineness degree sliver brings, in addition; If it is greater than 50%, then there are the feel of resulting woven fabric and the situation of degraded appearance.
In cloth and silk material of the present invention, be necessary that dipping adheres to resin to reduce gas permeability in the base cloth that is made up of the polyester fiber woven fabric.Also can use on non-cracking ground even receive big blast, be necessary to make cloth and silk itself to have the retractility of appropriateness in order to make the full wind of making by cloth and silk material of the present invention of sports requsites drum.Therefore, the resin of giving base cloth must be the resin of the character that can keep such, considers the optimization polyurethane resin from viewpoints such as versatility, economy, operability.When resins such as use acrylic resin, Corvic, though can reduce gas permeability, the hardening of cloth and silk material own, when therefore receiving big blast at the full wind of drum, the retractility of cloth and silk itself diminishes and might rupture, and is therefore not preferred.
Polyurethane resin has ethers polyurethane resin, ester class polyurethane resin, carbonates polyurethane resin etc.; But during these polyurethane resins of known use; If before resin finishing, do not carry out WATER REPELLENT TREATMENT, then can't obtain good TEAR STRENGTH as pre-treatment.The inventor has carried out deep research to the polyurethane resin that uses among the present invention, and the result finds before giving polyurethane resin, to there is no need to carry out pre-treatment through using the polycarbonate-based polyurethane resin of organosilicon copolymerization, can have high TEAR STRENGTH.And find, through using such resin, abrasion intensity is improved.
The polycarbonate-based polyurethane resin of organosilicon copolymerization is in preparation during polycarbonate-based polyurethane resin, makes the particularly resin that forms of organopolysiloxane copolymerization and modification of itself and organo-silicon compound.
The polycarbonate polyurethane resin composition can prepare through the condensation reaction of PCDL, organic multiple isocyanate, aklylene glycol and diamine compound.As PCDL, can enumerate 1,6-hexyl carbonate glycol, polyhexamethylene carbonic acid ester glycol, polytetramethylene carbonic acid ester glycol, poly-5-methylene carbonate glycol, gather heptamethylene carbonic acid ester glycol etc.Wherein, preferred 1,6-hexyl carbonate glycol.As organic multiple isocyanate; Can enumerate dicyclohexyl methyl hydride-4, aliphatic or alicyclic diisocyanates such as 4-vulcabond, hexamethylene diisocyanate, IPDI, two (isocyanates methyl) cyclohexane, lysine isocyanates; And Toluene-2,4-diisocyanate; 4-vulcabond, Toluene-2,4-diisocyanate; 6-vulcabond, diphenyl methane-4; 4 '-vulcabond, diphenyl methane-2,4 '-vulcabond, PPDI, ditolyl vulcabond, 1, aromatic diisocyanates such as 5-naphthalene diisocyanate, xylene diisocyanate.Wherein, preferred dicyclohexyl methyl hydride-4,4-vulcabond.As aklylene glycol, can enumerate 1,6-hexylene glycol, 1,4-butanediol, 1,5-pentanediol etc.Wherein, preferred 1, the 6-hexylene glycol.As diamine compound, can enumerate IPD, toluenediamine, tetramethyl hexamethylene diamine, hexamethylene diamine etc., wherein, preferred IPD.
When carrying out this condensation reaction, preferably, can make the organo-silicon compound with 1000~12000 molecular weight, preferred organopolysiloxane compound copolymerization.The preferred one of which of an above-mentioned organo-silicon compound end group has 2-CH
2OH base (primary alconol residue), another end group right and wrong are reactive, for example, and the preferred compound that uses with following chemical constitution.
[wherein, R representes alkyl, and n representes 2~130 integer, and Me representes methyl]
In the organo-silicon compound of following formula, has 2-CH in the end group in left side
2OH base (primary alconol residue), the end group-SiMe on right side
3It is non-reactive group.Copolymerization with organo-silicon compound in, when its two end groups all are the primary alconol residue,, then have the inadequate situation of TEAR STRENGTH of resulting cloth and silk material if use for example following organo-silicon compound.
In the polycarbonate-based polyurethane resin of organosilicon copolymerization used in the present invention, the content of organosilicon copolymer composition is preferably 3~15 quality % with respect to the quality of polycarbonate-based polyurethane resin composition, more preferably 5~10 quality %.In addition, the molecular weight of the polycarbonate-based polyurethane resin of organosilicon copolymerization is preferably 30,000~500,000, and more preferably 50,000~350,000.
In the polycarbonate-based polyurethane resin of organosilicon copolymerization; If silicone ingredients contain quantity not sufficient 3 quality %, then exist the cloth and silk material that obtains mechanical strength, particularly wear and tear the inadequate situation of intensity, in addition; If it surpasses 15 quality %; Then the friction of cloth and silk material reduces, and between cloth and silk, is easy to generate slip, has the unfavorable condition of coiling property variation.In addition, the molecular weight deficiency of the polycarbonate-based polyurethane resin of organosilicon copolymerization 30,000 o'clock produces the unfavorable condition that can't fully improve TEAR STRENGTH sometimes, and in addition, if it surpasses 500,000, then viscosity increases, and produces the unfavorable condition of dipping property reduction sometimes.
The quality of the base cloth woven fabric in the cloth and silk material of the present invention, for the fracture strength that keeps cloth and silk material and TEAR STRENGTH in proper level, be preferably 20~80g/m
2, 30~75g/m more preferably
2If the mass deficiency 20g/m of base cloth woven fabric
2, then can't obtain sufficient fracture strength, fracture easily becomes when receiving high blast.In addition, it surpasses 80g/m
2The time, because the adhesion amount of resin becomes the ratio ground of a certain degree to increase with the woven fabric quality, so the quality of cloth and silk becomes excessive, not only the gliding ability of resulting sports requsites reduces, and the carrying inconvenience that also becomes.
In cloth and silk material of the present invention, the resin adhesion amount is 5~40 quality % with respect to the woven fabric quality optimization, more preferably 10~35 quality %.If resin adhesion amount less than 5 quality % though the TEAR STRENGTH of the cloth and silk material that then obtains improves, can't reduce gas permeability fully; This cloth and silk material drum is expired wind and can be utilized the performance of its blast insufficient, for example, and under the situation of kite surfboard or paraglider; Gliding ability reduces and becomes dangerous; In addition, under the lateen situation, utilize the performance of wind to reduce efficiently.On the other hand, when the resin adhesion amount surpassed 40 quality %, the quality of resulting cloth and silk material became excessive, and its processing operability significantly reduces, thereby not preferred.
Cloth and silk material of the present invention, if its quality is excessive, the gliding ability of the sports requsites that then not only obtains reduces, and also inconvenient during carrying, and in addition, for example spinnaker use cloth and silk material, and excessive cloth and silk quality causes its processing operability significantly to reduce.But if the cloth and silk quality is too small, then the fracture strength of this cloth and silk material and TEAR STRENGTH are not enough.Therefore, preferred cloth and silk weight of the present invention is 20~100g/m
2, 30~80g/m more preferably
2
Even for cloth and silk material of the present invention also can not torn after using repeatedly, its TEAR STRENGTH is necessary for more than the 29.42N (3.0kgf), is preferably 39.2N (4.0kgf)~98.0N (10.0kgf).During the not enough 29.42N of TEAR STRENGTH (3.0kgf), by the sports requsites that this cloth and silk is made, for example the kite surfboard is when gliding, and when perhaps spinnaker received high blast at the full wind of drum, the possibility of tearing uprised.
In addition, it is above with more than 10% that the TENSILE STRENGTH of cloth and silk material of the present invention and percentage elongation must be respectively 294.1N (30kgf)/5cm, preferably is respectively 400~700N/5cm and 10~25%.Usually, the fracture strength of cloth and silk material and percentage elongation according to the structure of woven fabric with have or not resin finishing etc. to change, if but improve TENSILE STRENGTH, then percentage elongation has the tendency of reduction.Even TENSILE STRENGTH is more than the 294.1N/5cm, when percentage elongation less than 10%, the toughness of this cloth and silk material is insufficient, therefore at the sports requsites of making by cloth and silk material at the full wind of drum suddenly, when receiving high blast, the danger of fracture uprises quickly.On the other hand, during TENSILE STRENGTH is not enough 294.1N/5cm, the sports requsites of being made by this cloth and silk material is because its low TENSILE STRENGTH, and when receiving high blast, fracture easily becomes.Therefore, two characteristics of percentage elongation that satisfy simultaneously more than the above TENSILE STRENGTH of 294.1N/5cm and 10% are important on the anti-breaking property that improves cloth and silk material.
And the air permeability of cloth and silk material is necessary for 1.0ml/cm among the present invention
2Below/second, be preferably 0.1ml/cm
2/ second below, 0.01ml/cm more preferably
2Below/second.The gas permeability of cloth and silk material surpasses 1.0ml/cm
2During/second, this cloth and silk material drum is expired wind and can be utilized the performance of its blast insufficient, and for example under the situation of kite surfboard or paraglider, gliding ability reduces and becomes dangerous, in addition, under the lateen situation, utilizes the performance reduction of wind efficiently.
And for fear of by using tearing of causing repeatedly or rupturing, the abrasion intensity of cloth and silk material of the present invention is necessary for more than 75 times, more preferably more than 100 times.This be because, if abrasion undercapacity 75 times, then when using repeatedly, at the sports requsites of making by the cloth and silk material full wind of drum and when receiving high blast, the danger that ruptures at worn out position increases suddenly quickly.
In the manufacturing of cloth and silk material of the present invention, polyurethane resin adopts infusion process or rubbing method to the not special qualification of the adding method of base cloth woven fabric.In addition, also can carry out infusion process, two kinds of methods of rubbing method.No matter which kind of method must make polyurethane resin fully soak into and flood in the inside of base cloth woven fabric and adhere to, thereby give resulting cloth and silk material sufficient rerum natura, for example TENSILE STRENGTH, TEAR STRENGTH, abrasion intensity, air permeability.
In addition, polyurethane resin floods when adhering to the base cloth woven fabric with liquid state, and this liquid resin can be a water system, also can be non-water system.
Base cloth of the present invention does not have special qualification with the cross sectional shape of the contained polyester fiber of woven fabric, can have polygons such as common round-shaped, triangle, square shape, hexagonal configuration, elliptical shape, flat pattern, or have 2 abnormity (irregular) shapes such as shape with upper process.In these special-shaped shapes, preferably have flat pattern, the maximum long axis length of flattened cross-sectional shape is with respect to the ratio of minimum minor axis length at this moment, and promptly flat ratio is preferably 3~6, further is preferably 3~4.In such flattened cross-sectional shape, preferably its flat pattern is preferred 2~6, more preferably 3~5 flat concaveconvex shapes that circle is overlapped each other and connected along the major axis in cross section.When the number of the circle that connects is 2~6, for such flat pattern, have 2~6 protuberances and 1~5 recess in each side of its major axis, these protuberances become symmetric shape about major axis in its both sides with recess.In so flat concavo-convex cross sectional shape, if the number of circle connected to one another is 2~6, then its cross-sectional area is big with the difference of area of circle that with its major axis is diameter, and the air permeability of resulting woven fabric suitably reduces.On the other hand; If the number of circle connected to one another is more than 7; The fusion warp thread formability that then has the fiber of such shape of cross section reduces, and produces sometimes on the sliver of the flat concavo-convex shape of cross section that obtains the uneven problem of dyeing takes place easily.
In above-mentioned flat concavo-convex shape of cross section, the diameter of preferred circle connected to one another is equal to each other, and protuberance that preferably is mutually symmetrical about major axis and recess are with respect to the meet at right angles ratio W of ground width measured of major axis
1/ W
2Be 1.1: 3.0, further be preferably 1.1: 2.0.And when the diameter of above-mentioned circle connected to one another differed from one another, preferably its maximum gauge was 1~5 times of minimum diameter, is preferably 1~2 times.
