Description

[Detailed description of the invention]

[0001]

[Industrial application field]

The present invention relates to a resin-treated fabric having excellent peel strength and durability, a method for producing the same, an airbag, and a canvas. [0002]

[Conventional technology]

[Conventional technology] Conventional methods for improving the peeling strength of resin-treated fabrics include: ■ using a low-viscosity processed resin to improve resin penetration by applying it multiple times; and ■ applying resin with different heat shrinkage properties. Woven fabrics made of composite yarns, mixed yarns, or mixed yarns of low-shrinkage yarns and high-shrinkage yarns using polymers of different types or more are heat-treated to create voids in the woven yarns, and the processing resin There are methods to improve permeability. [0003]In recent years, the need for airbags for the safety of vehicle occupants has been rapidly increasing. When a car crashes, a sensor receives the shock of the collision and generates high-pressure gas using an inflator (high-pressure gas generator). This is to prevent movement and ensure safety. Conventionally, such airbags have a weight of 400 to 1000
A plain weave fabric made of denier nylon 6.6 filament yarn coated on one side with synthetic rubber or natural rubber such as chloroprene or chlorosulfonated olefin was used. In addition, the canvas used has been formed by, for example, impregnating or coating a plain fabric with a resin using the above-mentioned resin processing method. [0004]

[Problem to be solved by the invention]

When such conventional resin-treated fabrics are formed by the method (2) above, it is necessary to layer the resin to a predetermined thickness, so it is common to apply it many times, which poses problems in terms of complicated processes and increased costs. Moreover, it had the disadvantage that no significant improvement in peel strength could be expected. In addition, method (2) has the disadvantage that the strength of the weaving yarn after heat treatment becomes extremely weak rather than improving the peel strength. [0005]Next, since all conventional airbags are instantaneously inflated using high-temperature, high-pressure gas from an inflator, they have the disadvantage that the fabric and resin layer tend to separate easily. In addition, airbags are generally stored in a folded state in a narrow space such as a steering wheel or instrument panel until just before they are activated.
Furthermore, they are often stored for long periods of time in conditions where the environment such as temperature, humidity, and even ozone changes, resulting in the disadvantage that the fabric and resin layer are likely to separate. [0006] Furthermore, even if the conventional canvas is treated with resin as described above,
It is not possible to improve the peeling strength of the resin used,
It had poor durability. In view of the drawbacks of conventional resin-processed fabrics, airbags and canvases, it is an object of the present invention to provide resin-processed fabrics, airbags and canvases that have less reduction in the strength of weaving yarns and have excellent peeling strength between the fabric and the resin layer. It is an object of the present invention to provide a method for stably producing the resin-treated woven fabric. [0007]

[0011] Further, the airbag of the present invention has on its surface a bag body of the airbag made of the resin-treated fabric as described above, and the canvas of the present invention has the airbag body formed of the resin-treated fabric as described above. The surface of the canvas shows that the base fabric of the canvas is made of a woven fabric. [0012]

[Effect]

The present invention provides a fabric made of filament yarn as a weaving yarn,
If the specific structure described below is used, the permeability coefficient will be 1 x 10-3.
It was completed after discovering that the adhesion of the resin to the resin processed product was significantly improved, and the adhesion of the resin to the resin-processed product was surprisingly improved. [0013] That is, the permeability coefficient at the stage of gray fabric is 1×10 to 5
For example, if a water permeability channel is formed in a fabric with a basis weight of 100 to 400 g/m2, which is on the order of It is formed in the direction of
When resin is applied, it is absorbed through this water permeation passage. Therefore, when viewed from the cross section of the fabric, the resin permeates in a striped manner, as if the resin were enveloping the fabric, thereby exhibiting a remarkable effect of improving adhesion. [0014] The present invention has investigated this fact and succeeded in significantly improving the adhesiveness of textiles using filament yarns, which were conventionally considered to have poor adhesiveness. [0015] The warp and weft yarns constituting the fabric of the present invention are composed of filaments, and such filaments include, for example, polyamide fibers such as nylon 6, nylon 6.6, nylon 12, and nylon 4.6; Aramid fibers represented by copolymers with phenylene terephthalamide and aromatic ether, polyester fibers represented by polyalkylene terephthalate, vinylon fibers, rayon fibers, ultra-high molecular weight polyethylene fibers, paraphenylene sulfone, polysulfon, etc. Continuous fibers such as synthetic fibers such as sulfon fibers and polyetherketone fibers, and inorganic fibers such as carbon fibers, glass fibers, and metal fibers can be used. [0016] Such filaments may contain various additives that are commonly used to improve productivity or properties in the manufacturing process or processing process of the raw yarn. For example, heat stabilizers, antioxidants, light stabilizers, smoothing agents, plasticizers, thickeners, pigments, flame retardants, gloss-imparting agents, and the like can be included. [0017] The filament used in the present invention may be raw silk or processed filament, but it is preferably used that has substantially no twist or extremely low twist. JP-A-3-294542 (IQ) [0018] That is, in the present invention, it is necessary to form a water permeation passage described below in a high-density fabric with a cover factor of 20 or more, but it is not possible to form such a passage with a high twist yarn. Can not do it. Water permeation channels are conveniently formed only in the above-mentioned woven yarns which have adequate inter-fiber flexibility. [0019] Such substantially no twist or extremely low twist means, for example, preferably 120 T/m or less, more preferably 20 T/m
Refers to yarn that has only the following twists. The strength of the warp and weft yarns, that is, the single fibers that make up the weaving yarns, is not particularly restricted, but in the case of industrial materials, they can be selected appropriately depending on the application, but in the case of canvas, it is preferable to The single fiber strength is preferably 5 g/d or more, preferably 6 g/d or more in the case of an airbag, and more preferably 7 g/d or more in any case. [0020] The fineness of the single fibers constituting the weaving yarn can be selected depending on the purpose, just like the single fiber strength above, but for example, in the case of industrial materials such as airbags and canvas, the fineness of the fibers used should be selected. Although it depends on the yarn strength, Young's modulus, etc., it is preferably 1 d or more, more preferably 4 d or more. [0021] Although the total fineness of the weaving yarn is not particularly limited,
In the case of industrial use, 150 to 3000D is preferable,
More preferably it is 200-1500D. [0022] The structure of the filament fabric in the present invention includes plain weave,
Tangled weave, satin weave, variations thereof, multi-axis weave, etc. can be used. Among such textiles, plain weave and multiaxial weave are preferably used because they have excellent mechanical properties as resin-treated textiles. [0023] The present invention provides that when such a textile is treated with a resin, the peeling strength between the resin and the textile is significantly improved if the textile has a specific structure (water velocity passage = water permeability coefficient). This is what we have investigated. [0024] That is, the fabric has a basis weight of 100 to 400 g/m2, and preferably has a cover factor of the constituent yarns of 20 or more, more preferably 22 to 35, and is compliant with JIS A-
The permeability coefficient (K) measured according to 1218 is 1×10
-3 to 5X10-2 preferably lXl0 to 9x10
Those in the range of -3 have water permeation passages within the yarn structure constituting the fabric, and it has been determined that these passages have a unique effect on the resin. When the resin processing is applied, the water permeation passage can be easily identified because the resin permeates in the thickness direction of the fabric in a streaky manner and remains as a streaky portion within the cross-sectional structure of the woven yarn. [0025] The above-mentioned cover factor (CF) is a numerical representation of the degree of crowding of the yarns constituting the fabric, and is determined by the following formula. CF = N, (D1/2/ρ1/2) where CF: cover factor: textile constant (plain weave = 0.0168) N: weave density (strands/1 nch) D: fineness (denier) ρ: A woven fabric having a woven fiber specific gravity, for example, a cover factor (CF) of less than 20, tends to have gaps between the constituent yarns or become a woven fabric with openings, and it is difficult for such a woven fabric to achieve the effects of the present invention. [0026] The woven fabric having the above-mentioned specific structure can be treated with a high pressure liquid flow to form a path for the liquid flow in the woven yarn structure in the axial direction of the woven yarn or in the thickness direction of the woven fabric. can be manufactured. For example, if water jet punching is continued to be applied to the fabric in a batch manner, water permeation passages will gradually be formed within the yarn structure, and eventually water will permeate much more vigorously than at the beginning. This means that water permeation passages were formed within the yarn structure of the fabric. Once this passage is formed, it must be
D'44 (11) permeates through this path to the back side of the fabric and rarely forms a path again at other locations, so it is not easily destroyed and is retained within the yarn structure. Fabrics with such a special yarn structure have a significantly high coefficient of water permeability. For example, in a filament plain woven fabric with a basis weight of 250 g/m2, the gray fabric has a water permeability coefficient of 5 x 10-5, whereas the fabric having the specific structure of the present invention obtained by subjecting the gray fabric to the water jet punching process described above has a 260
A plain woven fabric of g/m 2 has a permeability coefficient as high as 2×10′. [0027] This phenomenon is caused by the fabric having the above-mentioned specific yarn structure, and is caused because the fabric has a water velocity passage. That is, when a resin liquid is applied to this water velocity passage, a structure is created in which the resin penetrates in the thickness direction of the fabric in streaks as shown in FIG. 1, and the anchoring effect is greatly increased. [0028] FIG. 1 is a schematic side cross-sectional view of the resin-treated fabric of Example 3. In the figure, 1 is a resin coating layer, and 1'
is the base resin layer. 2 is the warp and 3 is the weft. When subjected to high-pressure water jet treatment, water velocity passages are formed in the warp threads 2 or weft threads 3, and the resin permeates into the passages to form streaks 4. The lines 4 run randomly in the thickness direction of the fabric and in the direction in which the threads are arranged, and are intricately bent. Therefore, bent portions are observed depending on the cross-sectional location. This is the resin streak 4 that exists isolated in the center of the weft in the figure. [0029] The above-mentioned water velocity passage can be expressed by the water permeability coefficient measured according to JIS A-1218, and the woven fabric in the range of 5 x 10-2 has a permeability of the resin when processed with resin. is significantly improved, and as a result, it exhibits the effect of providing high peel strength. [0030] As mentioned above, the hydraulic conductivity in the present invention is based on JIS A-1
It was measured in accordance with 218 "Soil permeability test, test method", but in short, it was measured and determined according to the standard except that a sample fabric was set in place of soil. However, the thickness of the sample fabric must be 3 mm or more.
(1:1) It is necessary to adjust it upwards and measure it. The water permeability coefficient of the present invention is a value measured uniformly at a thickness of 3 mm. For thin materials, measure by stacking multiple sheets and adjusting the thickness to 3 mm. [003] Looking at the resin-treated fabric of the present invention from another perspective, it can be expressed as follows. [0032] That is, the porosity (x) of the warp yarns and weft yarns on the side in contact with the coating surface among the yarns constituting the fabric of the present invention
and surface exposure ratio (y), the former is in the range of 0.54 to 0.9, preferably 0.55 to 0.69, and the latter is in the range of 1.
．． It has a yarn structure in the range of 12 to 5.0, preferably 1.4 to 1.9. [0033] To explain this yarn structure in more detail, the porosity (
x) and the surface exposure rate (y) are expressed by the following formulas (1) to (3),
In other words, when satisfying 0.54≦x≦0.9・(1) y≧3x−0,5・(2) y≦10x−4・(3), an excellent weaving structure can be obtained. can be provided. [0034] The porosity (x) and surface exposure coefficient (y) in the present invention are:
Find it as follows. First, the porosity (x) is defined by the cross-sectional area (S1) defined by the surface line connected by a tangent on the coating layer side of the perpendicular cross section of the weaving yarn at the intersection point, and the porosity (x), which constitutes the weaving yarn. Cross-sectional area occupied by only single fibers without voids (S
), it can be determined by the formula, porosity = (Sl-3)/S1. [0035] Next, the surface exposure coefficient (y), as shown in FIG. From the length (L1) of and the length (L2) of the surface line connected by a tangent, it can be determined by the formula: Surface exposure rate=L1/L2. [0036] Although it depends on the viscosity, the coating resin generally comes into contact with the single fibers exposed on the surface of the weaving yarn, so the surface exposure rate (y)
The larger the value, the higher the peel strength. On the other hand, the larger the porosity (x) of the yarn, the better the permeability of the resin, and the peeling strength of the coating resin is generally only in contact with the single fibers exposed on the surface of the yarn, and the inner layer of the yarn Therefore, the voids existing in the inner layer of the yarn do not contribute to improving the peel strength in any way and reduce the mechanical strength of the yarn. [0037] By balancing the porosity (x) and surface exposure rate (y) of the yarn of the present invention, the single fibers on the surface of the yarn are disordered, the inner layer has a dense structure, and the mechanical properties of the textile are improved. It exhibits the effect of conveniently satisfying both strength and resin adhesive strength. [0038] When the porosity (x) is less than 0.54, the entire woven thread becomes dense and the single fibers on the surface of the woven thread are undisturbed, which is not preferable. If it exceeds 9, there will be many voids inside the yarn, which is not preferable. [0039] On the other hand, the surface exposure rate (y) is larger than the straight line represented by y=3x-0,5 and smaller than the straight line represented by y=10x-4. Substituting the above-mentioned porosity (x), y is 1.12 to 5.
The range is 0. [0040] To explain this graphically, as shown in FIG. 4, y=3
In a range smaller than x-0.5, the weaving yarn will have many voids inside, and although the porosity (x) is large, the surface exposure ratio (y) will be small, and the effect of improving peel strength will be small. , the mechanical strength of the weaving yarn is also unfavorable. On the other hand, in a range larger than y=10x-4, it is difficult to physically produce the fibers unless the single fibers are intentionally arranged. [0041] As the resin used in the present invention, those normally used for industrial purposes or clothing can be used, including those for impregnation, coating, bases such as binders, and laminated resin films. In that case, for example, resins having properties such as impermeability, heat resistance, and flame retardancy can also be used. Examples of such resins include chloroprene, chlorosulfonated olefins, vinyl chloride, chlorinated olefins, fluororesins, silicone resins,
Furthermore, polyimide resin, epoxy resin (epoxy resin,
Heat-resistant synthetic resins (elastomers) such as thermosetting resins (including vibration damping materials made of polyamide and inorganic fillers) and natural rubber can be used, but in addition, phosphorus-based flame retardants and halogen-based Synthetic resins containing ordinary organic and inorganic flame retardants such as flame retardants, such as urethane resins, acrylic resins, melamine resins, and polyester resins, can be used. [0042] The amount of such resin used is not particularly limited, but in the case of canvas it is preferably 10 to 600 g/m2, particularly preferably 30 to 300 g/m2, and in the case of airbags it is preferably 10 to 200 g/m2. m2, particularly preferably 30 to 15
It is 0g/m2. [0043] However, the woven fabric with the special structure of the present invention has extremely high peel strength even with a small amount of resin, and can achieve a reduction in the amount of resin and a thin film, and can also form a film with high peel strength even in a thin film. Therefore, it is particularly suitable for fields that require flexibility, such as clothing. [0044] Next, a method for manufacturing a resin-treated fabric of the present invention will be described. A woven fabric that satisfies the above-described hydraulic conductivity, porosity, and surface exposure ratio can be easily formed by using a high-pressure liquid flow treatment, preferably a high-pressure water flow treatment. That is, according to the high-pressure water jet treatment, the impact on the weaving yarns is strong, and it is possible to efficiently obtain a fabric having the above-mentioned weaving yarn structure. Process. [0046] Preferably, no processing conditions are used. [0047] To be applied. The resin processing here refers to impregnation or coating using a resin processing liquid made of the above-mentioned resin, or to forming a resin film in advance with the resin processing liquid and then painting this. [0048] or disversion or a mixed solvent type thereof may be used. A dehydrating agent and the like can be added. [0049] Coating methods include knife coating, roll coating, rod coating, extrusion coating, etc., and impregnation methods include padding method and pad-nip method. Impregnation treatment may be performed in advance using a treatment liquid. Further, as a laminating method, a method of applying a base resin (binder resin) as usual and then laminating a pre-formed resin film or a method of laminating a molten resin film can be adopted. Conditions that suit the purpose should be selected and used. [00503 The resin-treated fabric thus obtained has excellent peel strength from the resin, and can be suitably used for both industrial and clothing applications that require waterproofness. For industrial use, it is particularly suitable as a material for airbags and canvas. [0051]

【Example】

Next, the present invention will be explained in more detail with reference to Examples. [0052] Examples 1 to 5, Comparative Example 1.2 Total fineness 1000D1 Single fiber fineness 5.2d, strength 8
．． A plain woven fabric having a density of 25 warp and weft yarns/1 nch was prepared using 9 g/d polyethylene terephthalate fibers, subjected to high-pressure water jet treatment under the following conditions, and then dried and set in a conventional manner. Water pressure 2 6 levels of 5 to 150 Kg/Cm2 in Table 1 Nozzle diameter: 0.13 mmφ Nozzle spacing: 0.6 mm Processing speed: 10 m/min Next, a vinyl chloride resin liquid with a viscosity of 6000 cps was coated with a knife coat at 160 g/m2. One side was applied at the same amount. As a comparative example, a woven fabric was scoured, dried, and set in the usual manner without being flushed with high-pressure water, and the above-mentioned resin liquid was coated on one side with a coating amount of 160 g/m2 using a knife coat. Among these coated products, a cross-sectional photograph of the resin-treated fabric of Example 3 was taken, and a schematic diagram thereof is shown in FIG. Table 1 shows the physical properties of these coated fabrics.

[Table 1] [0053] JP-A-3-294542 (1B) [0054] As is clear from Table 1, in Examples 1 to 5, the breaking strength of the coated fabrics is large and the cover factor is increased. Despite this, the peel strength between the coating layer and the fabric remained at a high level. The coated fabrics of Example 3 and Comparative Example 1 were each sewn to form an airbag, and a rubber balloon was inflated inside the bag to adjust the internal pressure to 2 kg/cm 2 . [0055] As a result, the product of Example 3 was more flexible and had better shock absorption than the product of Comparative Example 1, and had a much better feel when struck by hand. [0056] Example 6 The total fineness was kept constant at 100OD, and the single fiber fineness was 1
．． 7d, 3.5d, 69d, strength 5 g/d, 6.2
Using polyethylene terephthalate filament yarns whose yield was changed to 8.5 g/d, a plain woven fabric having a density of 25 warp and warp yarns/1 nch was obtained. These fabrics were processed using a water pressure of 100 Kg/cm2 and a nozzle diameter of 0.13 mmφ.
After high-pressure water treatment with a nozzle spacing of 0.6 mm and a treatment speed of 5 m/7 min, the sample was dried and set in the usual manner. After that, a vinyl chloride resin liquid with a viscosity of 2000 cps was applied by the pad-nip method, and the amount of impregnated resin was 220 g/
Obtain m2 resin-treated fabric. The evaluation results of these coated fabrics are summarized in Table 2.

[Table 2] [0057] [0058] As is clear from Table 2, those with a small single fiber fineness tended to have a large decrease in break strength. Those with a large single fiber fineness tended to have a slight decrease in peel strength, but those with a high filament strength had almost no change in peel strength and had a large breaking strength, which was preferable. [0059] Example 7, Comparative Example 3 Total fineness 500D, single fiber fineness 5.2d, strength 8
．． A plain woven fabric having a density of 47 warps/1 nch and 34 wefts/1 nch was woven using 5 g/d polyethylene terephthalate filament yarn. This plain woven fabric was processed using a water pressure of 75 kg/cm2 and a nozzle diameter of 0.13 mmφ.
After high-pressure water treatment with a nozzle spacing of 0.6 mm and a treatment speed of 5 m/7 min, the sample was dried and set in a conventional manner. The fabric thus obtained was then given a viscosity of 2000 cps.
It was impregnated with a vinyl chloride resin solution by the pad-nip method. The amount of resin impregnated was 120 g/m2. A vinyl chloride resin sheet having a thickness of 0.2 mm was layered on one side of this resin-impregnated fabric, and the sheet was pasted through a calender roll heated to 170°C. As Comparative Example 3, the woven gray fabric was not subjected to high-pressure water jet treatment, but was scoured, dried, and set in a conventional manner, and the rest of the fabric was subjected to the same treatment as in Example 7. The evaluation results of these resin-treated fabrics are summarized in Table 3. [00601

[Table 3] [0061] As is clear from Table 3, those of Example 7 are different from those of Comparative Example 3.
It was confirmed that the peeling strength between the vinyl chloride resin layer and the fabric was significantly improved, and the breaking strength was also greater, making it an excellent and durable material that can be used as canvas. When the cross section of Example 7 was observed with a microscope, it was found that Figure 1
As shown in the figure, the base resin penetrated into the fabric in streaks in the thickness direction. On the other hand, in Comparative Example 3, the base resin was solidified only in the surface layer of the fabric, and no resin penetrating into the fabric in the thickness direction could be observed. [0062] Examples 8 to 10, Comparative Examples 4 to 6 Total fineness 1000D, single fiber fineness 5.2d, strength 7
．． A plain woven fabric with a density of 25 warp and weft yarns/1 nch was produced using 1 g/d polyethylene terephthalate fiber, and after high-pressure water treatment under the following conditions, it was smelted, dried, and set using the usual method. . Water pressure: 5.10.30.100Kg/cm2 Nozzle diameter: 0.13mmφ Nozzle spacing: 0.6mm Processing speed: 10m/min Next, a chloroprene rubber solvent solution with a viscosity of 6000 cps was applied at a coating amount of 105g/m2 using a knife coat. Coated on one side. Separately, a woven fabric was scoured, dried, and set in the usual manner without high-pressure water flow, and a chloroprene rubber solvent solution was coated on one side with a coating amount of 105 g/m2 using a knife coat. After impregnating these coated products with resin to prevent the movement of the single fibers that make up the weaving threads, the coated products were cut, cross-sectional photographs were taken, and the porosity (x) and surface exposure rate (y) were determined.
I asked for Table 4 shows the physical properties of these coated fabrics. [Table 4] [0063] [0064] As is clear from Table 4, in Examples 8 to 10, the breaking strength of the coated fabric was large, and the peeling strength between the coating layer and the fabric was significantly improved. .

After high-pressure water treatment under the conditions of mmφ, nozzle spacing of 0.6 mm, and processing speed of 5 m7 minutes, scouring, drying, and
I set it. Thereafter, a chloroprene rubber solvent solution with a viscosity of 6,000 cps was applied using a knife coat at a rate of 100 g/m2.
It was coated on one side with a coating amount of . Next, the porosity and surface exposure ratio were determined in the same manner as in Example 8. The evaluation results of these coated fabrics are summarized in Table 5.

[0066] [0067] As is clear from Table 5, the same tendency as in Example 6 was shown. In other words, the single fiber fineness has almost no effect on the peel strength, but the smaller the single fiber fineness, the greater the decrease in the breaking strength, and the larger the single fiber fineness and fiber strength, the lower the peel strength. There was almost no change, and the breaking strength was large and desirable. [0068]

【Effect of the invention】
