Description

[Detailed description of the invention]

[Technical Field of the Invention] The present invention relates to the improvement of base materials for sails, and more particularly, the present invention relates to improvements in base materials for sails, and more particularly, a fabric treated with a silane coupling agent is bonded to at least one side of a biaxially stretched polyester film via an adhesive layer. The present invention relates to a laminated sail laminate. [Prior art] Instead of the conventional fabric impregnated with resin as sail cloth for yachts and windsurfing,
In recent years, laminates with plastic films have appeared (for example, Japanese Patent Laid-Open No. 58-51147). These utilize the well-balanced strength of plastic film in terms of length, width, and bias, and have both the tear strength and tear strength of fabric. Conventionally, adhesives, hot melt adhesives, cross-linked adhesives, and the like have been used to laminate these plastic films and fabrics. However, as in the past, when the film and the fabric are integrated using an adhesive, a hot melt adhesive, or a thermosetting adhesive, there are the following drawbacks. (1) When sailing: Vivid colors are preferred in order to emphasize fashionability, but if the sail is submerged in water, the color will darken and the fashionability will be impaired. Also, the sails become heavy and the handling is poor. In particular, it is heavy and requires a large amount of force to raise the sail from the water surface at the start of windsurfing. (2) While at anchor: The sail has poor resistance to rubbing, so when the sail is rolled up or folded for storage, or when it is attached to a pole for reuse, it gets rubbed, causing many wrinkles in the sail and causing whitening in those areas. The appearance is extremely deteriorated and the running performance is also adversely affected. (3) During manufacturing: If dyed or printed fabric is used, the rubbing resistance of the laminate will decrease, and when the film and fabric are bonded together using a thermocompression roll, dyes and pigments will be transferred to the thermocompression roll, resulting in color loss. Unevenness,
Causes roll stains. [Object of the Invention] The object of the present invention is to eliminate the above-mentioned drawbacks, that is, to eliminate the change in color tone when submerged in water without reducing the texture and tear strength, and to prevent sails from easily raising.
The object of the present invention is to provide a laminate for a sail having excellent kneading resistance. Furthermore, it is an object of the present invention to provide a laminated body for sails which is free from transfer stains of rolls due to dyes and pigments during the manufacturing process and which is free from color unevenness. [Configuration of the Invention] In order to achieve the above object, the present invention has the following configuration:
That is, a polyester biaxially stretched film with a thickness of 15 to 125 μm is coated with an adhesive layer of 5 to 100 μm in thickness on at least one side, and is made of short or long fibers with a single filament fineness of 0.5 to 20 deniers and has a basis weight of 20 to 200 g/m ² . In the laminate in which the fabrics are laminated, the Si _2P /C _1S relative integrated intensity ratio is 0.01
This is a laminate for sails characterized by being treated to a concentration of ~0.1. The polyester biaxially stretched film referred to in the present invention refers to a biaxially stretched film (hereinafter referred to as PET) made from polyethylene terephthalate (hereinafter abbreviated as PET), polyethylene naphthalate, polybutylene terephthalate, and copolymers thereof as main raw materials.
Biaxially stretched film is abbreviated as BO film). Particularly preferred is a BO film made of PET and a copolymer containing 90 mol% or more of the PET component. The following will explain the case of PET-BO film as an example. The thickness of PET-BO film is 15-125μ,
It is preferably 20 to 100μ, and the adhesive layer surface may be a PET-BO film that has been subjected to discharge treatment, matting treatment, pattern printing, coloring, and primer treatment. It may also be a PET-BO film containing dispersed additives such as a weathering agent, a coloring agent, and a matting agent. The adhesive layer of the present invention is made of a well-known adhesive for bonding a PET-BO film and a fabric, and thermoplastic resins and thermosetting resins can be used. Specifically, they include copolymerized polyester, polyester ether, polyacrylate, polymethacrylate, polyurethane, epoxy adhesive resin, amide adhesive resin, glycidyl methacrylate copolymer, and the like. Particularly preferred examples are copolymerized polyesters and glycidyl methacrylate copolymers. A blend of copolymerized polyester with epoxy resin, amide resin, or polyolefin can also be used. The thickness of the adhesive layer is 5~100μ, preferably 10~
It is 50μ, more preferably 10 to 40μ. Also,
A weather resistant agent, a heat resistant agent, a coloring agent, etc. may be dispersed and blended into the resin used for the adhesive layer. Note that the thickness of the adhesive layer is determined by taking a cross-sectional photograph of the sail laminate in the thickness direction, and calculating the thickness from the photograph using the following method. In other words, when the shortest distance between the fibers that make up the fabric bonded to the adhesive layer and the BO film is A, and the longest distance is B, (A+B)/
2 is the thickness of the adhesive layer. The thickness of the adhesive layer measured in this way is the thickness of the adhesive layer after melt-extruding or coating the adhesive layer resin on the BO film before laminating the fabric.
Almost equal to the thickness of the adhesive layer when dry. In the present invention, the fabric refers to short fibers or long fibers having a single yarn fineness of 0.5 to 20 denier (hereinafter denier is abbreviated as D), preferably 1 to 10 D, and a fabric weight of 20 to 200 g/m ² , preferably Woven, knitted or non-woven fabrics weighing 30-150g/ ^m2 . The fibers that make up the fabric are synthetic fibers such as polyester and polyamide.
Or natural fibers. Especially PET and PET
Fabrics made of copolymer fibers containing 90 mol% or more are preferred. Further, a fabric that has been dyed, softened, or corona discharge treated may be used. The fibers constituting the fabric may be fibers containing dispersed additives such as weather resistant agents, colorants, heat resistant agents, and inorganic fine particles. The thickness of the BO film is 15μ, the thickness of the adhesive layer is 5μ,
If the single yarn fineness of the fabric is less than 0.5D and the basis weight is less than 20g/m ^{2 ,} the disadvantage is that the sail laminate has weak tensile strength in the bias direction, adhesive strength, and tear strength. The thickness of the BO film is over 125μ, the thickness of the adhesive layer is 100μ, and the fineness of the single yarn of the fabric is
If the fabric weight exceeds 20D or 200g/m ² , the sail laminate becomes hard, has poor texture, and has poor sewing workability and handling. The epoxy silane coupling agents and amino silane coupling agents used in the present invention are represented by the following general formulas (a) to (e). [However, m = 0 or 1, n = an integer of 1 to 10, R' = a hydrocarbon residue selected from an alkyl group having 1 to 10 carbon atoms, a phenyl group, and a cyclohexyl group, R'' = a carbon number of 1 to 10 10 alkyl groups] Typical examples of epoxy silane coupling agents include γ-glycidoxypropyltrimethoxysilane and γ-glycidoxypropyltriethoxysilane. , γ-glycidoxypropylmethyldimethoxysilane, γ-glycidoxypropylmethyldiethoxysilane, β(3,4-epoxycyclohexyl)ethyltrimethoxysilane, etc. In particular, silane coupling agents of general formula (A) is preferred, and it is even more preferred to use γ-glycidoxypropyltriethoxysilane. Typical examples of aminosilane include γ-glycidoxypropyltriethoxysilane.
-(2-aminoethyl)aminopropyltrimethoxysilane, γ-(2-aminoethyl)aminopropyltriethoxysilane, γ-(2-aminoethyl)aminopropylmethyldimethoxysilane,
Examples include γ-(2-aminoethyl)aminopropylmethyldiethoxysilane, γ-aminopropyltrimethoxysilane, and γ-aminopropyltriethoxysilane. In particular, silane coupling agents of general formula (d) are preferred, and γ-(2-aminoethyl)
Preference is given to using aminopropyltriethoxysilane. Each of these silane coupling agents may be used alone, or one of them may be used as the main component and a small amount (for example, 10 wt % or less of the total silane coupling agent) of the other silane coupling agent may be added.
The reason for limiting the number of silane coupling agents is that ordinary vinyl silane, mercapto silane, methyl silane, chloro silane, etc. are not effective. The Si _2P /C _1S relative integrated intensity ratio referred to in the present invention is
A value calculated from the peak areas of C _1S and Si _2P obtained by measuring a fabric treated with a silane coupling agent using an ESCA (photoelectron spectrometer) (details will be described later), and is a parameter that indicates the degree of treatment with a silane coupling agent. It is. Si _2P /C _1S is 0.01 to 0.1, preferably 0.02
-0.07, more preferably 0.03-0.05. Si _2P /
If C _1S is less than 0.01, the color tone when submerged in water, the ability to raise the sail, and the resistance to kneading will not be improved. Also
When Si _2P /C _1S exceeds 0.1, the tear strength of the laminate decreases, making it more likely to tear, becoming hard and having a poor texture. It is essential to treat the fabric with a silane coupling agent, and the object of the present invention cannot be achieved even if the adhesive layer is treated. Further, the treatment may be performed on the fabric alone before lamination, or on the surface of the fabric after lamination with biaxially oriented polyester. An example of fabric treatment with a silane coupling agent is shown below. Dissolve a predetermined amount of silane coupling agent in water, alcohols such as methanol, ethanol, butanol, aliphatic hydrocarbon solvent, aromatic hydrocarbon solvent, etc., and prepare in advance to obtain the desired Si _2P /C _1S intensity ratio. The concentration of the silane coupling agent is adjusted according to the calculated calibration curve, and hydrolysis is performed. Next, after immersing the fabric or a laminate of fabric and polyester BO film in this treatment liquid, the fabric is pulled up and the excess treatment liquid is squeezed out using a press roll.
dry. The Si _2P /C _1S intensity ratio depends on the immersion conditions of the fabric,
Although it cannot be determined unconditionally since it depends on the method of squeezing, the concentration of the treatment liquid is usually 0.1 to 40 wt%, preferably 0.5 to 10 wt%, when immersed for about 0.5 to 5 minutes. Drying temperature is usually 80~200℃, preferably 100~
Drying time at 170°C is usually 0.5 to 10 minutes, preferably 1 to 5 minutes, within a range that does not discolor the fabric. Next, a method for manufacturing a sail laminate according to the present invention will be explained using a PET-BO film as an example.
However, the present invention is not limited to these manufacturing methods. (1) Fabric treated with a silane coupling agent from one unwinder of a melt extrusion laminator with two unwinders (hereinafter referred to as silane-treated fabric)
Then, the PET-BO films are fed out from other unwinding machines. On the other hand, the adhesive layer resin is melted and extruded between the two from an extruder, and the two are pressed together using a press roll to obtain a laminate (laminate A) having the structure of [PET-BO adhesive layer silanized fabric]. Next, the material is passed through a thermocompression roll to adjust the adhesive strength as necessary, and then after-cured while being kept at a constant temperature to obtain a sail laminate of [PET-BO adhesive layer silane-treated fabric]. (2) Add the laminate (A) obtained by the method of (1) above to
Set it on the PET-BO film unwinder of the melt extrusion laminator in (1), and make a laminate in the same manner as in (1).
The adhesive layer resin is melt-extruded onto the PET-BO film surface of (A) and integrated with the silane-treated fabric by pressure bonding. Then, if necessary, after passing through a thermocompression roll, after-curing is performed to obtain a double-sided fabric type sail laminate of [silane-treated fabric adhesive layer PET-BO adhesive layer silane-treated fabric]. (3) Create a composite film by melt-extruding adhesive layer resin on PET-BO film [PET-BO adhesive layer], overlap it with silane-treated fabric, and integrate it with a thermocompression roll [PET-BO adhesive layer silane-treated fabric] ] Obtain a sail laminate. (4) Apply adhesive layer resin dissolved or dispersed in an organic solvent or water to one side of the PET-BO film using a gravure coater, reverse coater, bar coater, etc., and then volatilize the solvent.
It is heat-pressed and integrated with a silane-treated fabric using a press roll (laminate B). Then, after-curing is performed as necessary to obtain a sail laminate of [PET-BO adhesive layer silane-treated fabric]. (5) Apply an adhesive layer to the PET-BO surface of the laminate B obtained in (4) above in the same manner as in (4) above. The silane-treated fabric is then heat-pressed using a press roll to obtain a double-sided fabric sail laminate. (6) PET-BO in the melt extrusion laminator of (1) above
and untreated fabric are supplied and integrated via an adhesive layer to obtain a laminate of [PET-BO adhesive layer fabric]. After passing it through a thermocompression roll if necessary, it is immersed in a silane coupling agent solution, squeezed with a press roll, dried in a dryer, and then kept at a constant temperature for after-curing [PET-BO adhesive layer silane treated fabric]. Obtain a sail laminate. What are the after-cure conditions for each of the above manufacturing methods?
Although limited by heat shrinkage and thermal deterioration of PET-BO and fabric, it is usually desirable to carry out the reaction at an ambient temperature of 60 to 200°C, preferably 80 to 150°C, for 0.1 to 24 hours. Although the present invention is characterized by the above-mentioned sail laminate, the fabric surface of the laminate can be subjected to treatments known for fabrics such as antistatic treatment and anti-wrinkle treatment. Further, the film surface can be subjected to known processing treatments for films, such as antistatic treatment and surface hardening treatment. It is also possible to print or paste designs, letters, etc. on the fabric or film surface to increase the fashionability. [Effects of the Invention] The present invention creates a sail laminate by laminating a fabric treated with a specific silane coupling agent and a polyester biaxially stretched film via an adhesive layer, thereby improving the tear strength and texture of the laminate. It achieves the following excellent effects without reducing the (1) Eliminate the change in color tone of the laminate (sail) when it is submerged in water, and make it easier to raise the sail when submerged in water. (2) Excellent kneading resistance makes the sail easy to store. (3) When manufacturing a laminate for sails, the film and dyed or printed fabric are pasted together using a thermocompression roll, or a thermocompression roll is used to adjust the adhesive strength of the laminate between the film and the fabric. Since dyes and pigments are not transferred to the thermocompression roll during passing, there is no uneven color or roll stains. Note that the effects of the present invention were evaluated based on the following criteria. (1) Relative integrated intensity ratio of Si _2P /C _1S of fabric Using ESCA [photoelectron spectrometer (manufactured by Kokusai Denki Co., Ltd.)] with three sheets of silane-treated fabric superimposed to eliminate the influence of the sample stage of the measuring device, X-ray output 10kV using Al Ka rays (1486.6eV) as excitation X-rays,
Measure at 20mA. From the obtained C _1S (peak area indicating carbon concentration) and Si _2P (peak area indicating silica concentration), the concentration ratio of silica to carbon is calculated.
Calculate the Si _2P /C _1S relative integrated intensity ratio. (2) Resistance to kneading We conducted a test by hand kneading, which is normally done at sales. A 20cm square test piece was placed vertically and horizontally.
Rub the test piece strongly by hand 20 times and visually judge the peeling condition using the following criteria. ◎: No peeling is observed between the film and the fabric at the wrinkled portion. ○: Slight whitening of wrinkled areas. △: Whitening is observed in the wrinkled area. ×: Peeling occurs from the wrinkled portion. (3) Change in color tone upon immersion in water A test piece was immersed in water at room temperature, taken out after 1 minute, and observed with the naked eye for changes in color tone, which were evaluated based on the following criteria. ◎: No change in color tone was observed. ○: A slight change in color tone is observed. Δ: Considerable change in color tone is observed. ×: Significant change in color tone. (4) Tear strength According to JIS-P 8116, make a 20 mm cut in a test piece with a width of 63 mm and a length of 76 mm, and measure using an Elmendorf tear tester. The tear strength was determined by averaging the measured values in the warp and weft directions. (5) Texture The bending resistance in the warp and weft directions of the fabric was measured on both sides of the laminate according to JIS L-1096 Bending Repulsion A method (Gurley method), and the average value was taken. The larger the value, the harder it becomes and the texture becomes worse. [Example] Hereinafter, embodiments of the present invention will be described based on Examples.

36 filaments] weaving density, warp 112/weft 87
A taffeta with a weight per inch of 57 g/m ² was prepared, dyed with a red disperse dye, soaped, and washed with water. Using γ-glycidoxypropyltrimethoxysilane [Toray Silicone SH6040 (manufactured by Toray Silicone Co., Ltd.)] as an epoxy silane coupling agent and N/10 hydrochloric acid as a catalyst, an aqueous solution of pH 3 was prepared and heated to 10°C. It was hydrolyzed with Each aqueous solution having the concentration shown in Table 1 was prepared. Immerse the above taffeta in this aqueous solution for about 1 minute and squeeze out the excess aqueous solution with a roll to achieve a pick-up rate of 50%.
(Pickup rate = (W ₁ − W ₀ )/W ₀ ,
W ₀ : weight of fabric before treatment, W ₁ : weight of fabric after soaking). The fabric was then dried at 170°C for 2 minutes using a hot air dryer. As the polyester biaxially stretched film, a PET-BO film having a thickness of 38 μm was used, which was biaxially stretched 3.3 times vertically by 3.5 times horizontally from PET having an intrinsic viscosity (IV) of 0.62 and heat-set. Copolyester [terephthalic acid/isophthalic acid (56/44), ethylene glycol/butadiene glycol (32/68) (copolymerization molar ratio) (copolymerization molar ratio), molecular weight 23000, melting point 111°C] 80wt% and polyethylene [density 0.923, Melt index 4.0
g/10 minutes] A 20 wt% blend was used. Adhesive layer resin has a diameter of 40mm with a width of 360mm.
The taffeta was supplied to a melt extrusion laminator, and melt extruded at 240° C., and the above taffeta and PET-BO film were crimped with a nip roll through an adhesive layer (thickness: 20 μm). The obtained laminate with the structure of [PET-BO adhesive layer fabric] was passed through a thermocompression roll at 150℃ and a linear pressure of 10Kg/cm, then wound into a roll and stored in a heat treatment machine maintained at 100℃. After curing for 16 hours, a sail laminate of [PET-BO adhesive layer silane-treated fabric] was obtained. Si _2P of the silanized fabric of this sail laminate
Table 1 shows the C _1S relative integrated intensity ratio and evaluation results. This sail laminate had good tear strength and good kneading resistance without deteriorating the feel (comparison with Comparative Example 1 described below). In addition, the color tone did not change when immersed in water and was good. When I made a windsurf-in sail using this laminate and sailed it,
Raising the sail from the water was easier and easier than with the conventional product (Comparative Example 1, described below). Furthermore, when the sail was inspected after being sailed, folded, and stored repeatedly for one season, it was found that the PET-BO and fabric had not peeled off and had been stored well. Comparative Examples 1 to 4 Fabrics treated with epoxy silane coupling agent

Table 1 shows the evaluation results of this sail laminate. Comparative example 1 without silane coupling agent treatment, comparative example 2 with small Si _2P /C _1S relative integrated intensity ratio
It was of low quality as a sail because it lacked resistance to rubbing and the color changed significantly when submerged in water.
In addition, Comparative Examples 3 and 4 in which the Si _2P /C _1S relative integrated intensity ratio exceeded 0.1 had good resistance to rubbing, but the color became duller red than before silane treatment and lost its brightness. Shimatsuta. In addition, the tear strength is reduced and it is easy to tear, and in addition, the Gurley bending resistance value is large and hard.
The texture was bad. When I made and used a windsurf-in sail, it was stiff, stiff, and difficult to handle. Also, when we inspected the sail after one season of use, we found that it had peeled off from the crease. Examples 5 to 8 The taffeta used in Examples 1 to 4 was used as the fabric, and γ-(2-

Comparative Example 5, which used a fabric that was not treated with silane, and Comparative Example 6, which had a small relative integrated intensity ratio of Si _2P / C _1S , had poor kneading resistance and a large change in color tone when submerged in water, so they were of low quality for sale. It was hot. In Comparative Examples 7 and 8 in which the relative integrated intensity ratio exceeded 0.1, the color became duller red than before the silane treatment and lost its brightness. In addition, the tear strength was reduced and the texture was poor. Also, after using it for one season as a sale, peeling occurred at the creases. Examples 9 to 10, Comparative Example 9 The undyed taffeta used in Example 1 was printed in blue with pigment ink using an acrylic binder. The epoxy silane coupling agent aqueous solution (concentration 10 g/) used in Examples 1 to 4 and the amino silane coupling agent aqueous solution (concentration 10 g/) used in Examples 5 to 8 were mixed in 98 parts: 2 parts (implementation). Example 9), mixed in a ratio of 2 parts: 98 parts (Example 10),
A sail laminate of [PET-BO adhesive layer silane-treated fabric] was produced in the same manner as in Example 1. In addition, for comparison, a laminate was made using a fabric that was not subjected to silane treatment (Comparative Example 9). These evaluation results are shown in Table 1. Examples 9 and 10, which used fabrics treated with silane in the thermocompression roll process, had no roll stains, but in Comparative Example 9, which used untreated fabrics, the pigment was transferred to the hot rolls and the rolls were heavily stained, and the laminate was The color became uneven. Examples 9 and 10 had good rubbing resistance and no change in color tone when immersed in water. Windsurf-in sails made from this laminate were easy to raise from the water and easy to handle. The sale after one season of use was easy to store. On the other hand, Comparative Example 9 had poor rubbing resistance and darkened when immersed in water.
