Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fiber laminate for a vehicle. For example, the present invention relates to a vehicular fiber laminate used for vehicular interior materials such as vehicular seats.

[0002]

2. Description of the Related Art Fiber laminates for vehicles are used for interior materials for vehicles,
For example, it is used as a surface material of a vehicle seat. As described above, the structure of the vehicle fiber laminate used as the surface layer material of the vehicle seat or the like has a first layer, that is, a surface layer of a skin material, a second layer of a backing fabric, and a three-layer structure in the case of a two-layer structure. In this case, the first layer generally has a skin material, the second layer has a polyurethane foam, and the third layer has a backing fabric.

[0003] The vehicular fiber laminate constituted as described above has been conventionally required to ensure flame retardancy because it is used as an interior material such as a surface layer material of a vehicular seat. For example, JP-A-8-238708 discloses a fiber laminate for vehicles. The fiber laminate for a vehicle is composed of a skin material, a polyurethane foam, and a backing base fabric which is made of cellulosic fibers and has not been subjected to a flame-retardant treatment. The technology disclosed herein is a technology for controlling the burning speed of a fiber laminate for a vehicle by using a backing base fabric made of cellulosic fiber and not subjected to a flame-retardant treatment to secure the flame retardancy. there were.

[0004]

However, Japanese Patent Laid-Open Publication No.
In the fiber laminate for a vehicle disclosed in Japanese Patent No. 238708, the basis weight of the backing fabric made of the cellulosic fiber is 6%.
0 g / m ² or more, there is a further 70~80g / m ² is preferred. However it is preferably 60 g / m ² or more basis weight of the thus Uramoto fabric, is that the 70~80g / m ² is more preferable, the mass of the vehicle fiber laminate is increased, and also the production cost increases I will. That is, there has been a problem that it is not possible to reduce the weight and the manufacturing cost of the fiber laminate for a vehicle.

[0005] It is an object of the present invention to provide a fiber laminate for a vehicle, which can ensure flame retardancy, reduce the production cost, and reduce the weight.

It is another object of the present invention to provide a vehicular fiber laminate having a backing backing fabric that does not affect the elongation characteristics of the skin material.

[0007]

The inventors of the present invention have conducted intensive studies, and as a result of study, at least in a vehicular fiber laminate in which a skin material and a backing fabric are laminated, the backing fabric has a fiber length of 100 m.
m and a nonwoven fabric in which short fibers containing cellulosic fibers are entangled by a water jet method.

In the conventional vehicular fiber laminate, circular knitting has been used in most cases as the structure of the flame-retardant backing fabric. As described above, when circular knitting is used as the structure of the flame-retardant backing fabric, there is a problem that the basis weight of the backing fabric is increased in order to secure flame retardancy. Whereas the conventional vehicle fiber laminate uses circular knitting as the structure of the flame-retardant backing base fabric, the vehicle fiber laminate of the present invention has a fiber length of 100 mm or less as the backing base fabric. In addition, by using a non-woven fabric in which short fibers containing cellulosic fibers are entangled with each other by a water jet method, the weight per unit area of the backing base fabric can be reduced while ensuring flame retardancy.

Conventionally, circular knitting has been used as the flame-retardant backing fabric of the fiber laminate for vehicles because the backing fabric can be given flame retardancy and the elongation characteristics of the skin material of the fiber laminate for vehicles. Is not affected. In order to impart flame retardancy to the backing fabric, conventionally, a blended fiber of cellulose fiber and synthetic fiber such as polyethylene terephthalate fiber has been used. Here, the use of the cellulosic fiber is for improving the flame retardancy. Suitable textures for such blended fibers include nonwovens, especially spunbonded nonwovens, fabrics and knits. Also, in order not to affect the elongation characteristics of the skin material, the backing base fabric also needs to have excellent elongation characteristics. If the elongation characteristics of the backing base fabric are insufficient, the elongation characteristics of the skin material are impaired.

The woven fabric cannot be said to have sufficient elongation characteristics due to its structure, and it is not preferable to use the woven fabric as the structure of the backing fabric because it affects the elongation characteristics of the skin material. On the other hand, knitting, especially circular knitting, is excellent in elongation characteristics due to its structure. Circular knitting also has the advantage of being excellent in productivity in production, and has the further advantage that knitting of cellulosic fibers and synthetic fibers is possible and that mixed spinning yarn can be used. Therefore, knitted fabrics having excellent elongation characteristics, particularly circular knitting, have been conventionally used as the structure of the backing fabric.

However, considering the flame retardancy of knitting,
And the minimum basis weight is 60 g / m ^TwoNeed more
You. The knitting used for the backing base fabric is the cellulose-based fiber described above.
A stitch is made using a blend fiber of fiber and synthetic fiber.
This blended fiber is made into a cloth with continuous stitches and manufactured.
You. Circular stitches manufactured in this way have uniform stitches.
In addition, the stitches always create voids. This circle
Manufactures fiber laminates for vehicles using a knitted backing fabric.
Then, the surface of cushion material such as polyurethane foam or
Or, the surface of the skin material cannot be covered 100%. So this
Under such conditions, the basis weight of the backing fabric is 60 g / m^TwoAbove
Without it, the backing fabric could not achieve the flame retardant effect.

Usually, the basis weight of a general backing fabric which is the most common and has no special function is around 15 g / m ² ,
When circular knitting is used as the backing base fabric, the difference in the basis weight is 40 g / m ² . This leads to an increase in the mass of the fiber laminate for vehicles, and also causes an increase in manufacturing costs.

In addition, it is conceivable to add a flame retardant to the backing base fabric manufactured by circular knitting. Alternatively, it is also conceivable to reduce the stitch to make the coverage close to 100%. However, in this case, the mass of the backing base fabric is increased, and the productivity is reduced.

Therefore, in order to solve the above-mentioned problem, the nonwoven fabric is used as the backing fabric in the vehicular fiber laminate of the present invention.
By using the nonwoven fabric in this manner, a backing fabric that exhibits an excellent flame retardant effect even when the basis weight is small due to the uniform structure of the nonwoven fabric can be provided.

On the other hand, nonwoven fabrics manufactured by the spunbonding method, that is, spunbonded nonwoven fabrics conventionally used as a backing base fabric, are composed of long fibers, so that a cellulosic fiber and a synthetic fiber having a flame-retardant effect are used. Cannot be knitted, resulting in an inadequate elongation property.
The use of a flame-retardant non-woven fabric for a vehicular fiber laminate is conventionally impractical because the use of a non-woven fabric having insufficient elongation properties as the backing fabric affects the elongation characteristics of the skin material. Met.

That is, a spunbonded nonwoven fabric, which is a conventional general nonwoven fabric, forms a film-like fabric while randomly spinning long fibers, and in some cases, performs a fusing or pressure-bonding process to fix the fibers together. This is a non-woven fabric manufactured by the above method. Therefore, the nonwoven fabric thus manufactured is hardly stretched because the long fibers are intermittently entangled. That is, elongation characteristics are not sufficient. In the case where fusion processing is performed, the fixed portion further hinders elongation. Therefore, conventionally, a nonwoven fabric has not been used as a backing base fabric of a vehicular fiber laminate.

The nonwoven fabric used as the backing fabric of the fiber laminate for vehicles of the present invention is free from the above-mentioned disadvantages. That is, it is a non-woven fabric having a fiber length of 100 mm or less and short fibers containing cellulosic fibers entangled by a water jet method. It is made of staple fiber in this way, just using the water punch to entangle the fiber without using fused fibers or adhesives. I have. If the nonwoven fabric according to this manufacturing method is used as the backing base fabric for the fiber laminate for vehicles, the elongation characteristics of the nonwoven fabric are within the usable range, and the influence on the elongation characteristics of the skin material can be reduced. it can.

The non-woven fabric used as the backing fabric of the fiber laminate for vehicles of the present invention is a non-woven fabric entangled with water by a water jet method. That is, it is a nonwoven fabric manufactured by entanglement of webs made of short fibers, which are randomly laminated and formed into a sheet, using a water punch. In other words, fibers that are two-dimensionally entangled by the water punch are given a three-dimensional entanglement. The thus produced nonwoven fabric is uniformly entangled with the fiber to form a cloth film.

Further, since three-dimensional entanglement is given by the water punch, machine oil and other impurities hardly enter the nonwoven fabric. Conventionally, needle punching has been performed to impart three-dimensional entanglement to a sheet-like web when manufacturing a nonwoven fabric. However, when needle punching is performed, the needle touches the web, so that mechanical oil and other impurities attached to the needle may be mixed into the nonwoven fabric. When the machine oil is mixed, the flame retardancy is impaired and sanitary is not preferable. When other impurities are mixed, it is not preferable for sanitation. If the non-woven fabric is manufactured by the water jet method, such problems can be avoided, the flame retardant effect is not impaired, and the hygiene is preferable.

When such a non-woven fabric is laminated as a backing base fabric on a vehicular fiber laminate, the non-woven fabric does not have a stitch such as that of a circular knit, so that the surface of a cushion material such as a polyurethane foam or a skin material is not used. The surface can be coated 100%. Therefore, even if the basis weight of the nonwoven fabric used as the backing base fabric is small, an excellent flame retardant effect can be exhibited.

That is, since the nonwoven fabric having a small weight per unit area is used as the backing fabric in the vehicle fiber laminate of the present invention, an excellent flame retardant effect can be exhibited even with a small mass.

Further, since the nonwoven fabric having a small weight per unit area is used as the backing fabric, the manufacturing cost can be reduced.

Further, since the nonwoven fabric having excellent elongation characteristics is used as the backing fabric in the vehicular fiber laminate of the present invention, the elongation characteristics of the skin material are hardly affected.

The nonwoven fabric used in the vehicular fiber laminate of the present invention does not need to be subjected to a flame retardant treatment, so that it is not necessary to add a flame retardant, which is excellent in terms of the effect on the environment.

Furthermore, the nonwoven fabric used in the vehicular fiber laminate of the present invention is entangled with water by a water jet method, so that it is more sanitary than a conventional vehicular fiber laminate.

[0026]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a fiber laminate for vehicles (hereinafter, abbreviated as "fiber laminate" as appropriate) of the present invention will be described below. The fiber laminate of the present invention is a fiber laminate in which at least a skin material and a backing base fabric are laminated, wherein the backing base fabric has a fiber length of 100 mm or less and staple fibers containing a cellulosic fiber by a water jet method. A fibrous laminate characterized by being a tangled nonwoven fabric.

The fiber laminate of the present invention is a fiber laminate in which at least a skin material and a backing fabric are laminated. A commonly used skin material can be used for the fiber laminate.
For example, a woven fabric, a moquette, a tricot, a jersey, leather, artificial leather, a synthetic resin sheet, or the like can be used. In this case, it is preferable to use a skin material that has not been subjected to a flame retardant treatment. Even if the skin material is not subjected to the flame retardant treatment, in the fiber laminate of the present invention, the nonwoven fabric used for the backing base fabric suppresses the burning of the fiber laminate and ensures the flame retardancy of the fiber laminate. be able to. Further, since no flame retardant is added, the mass can be reduced accordingly and the productivity can be improved. Furthermore, it is excellent in terms of environmental impact.

A cushioning material may be laminated between the skin material and the backing fabric. By laminating the cushion material between the skin material and the backing base fabric, flexibility can be given to the fiber laminate. As the cushioning material, a commonly used material may be used, and for example, polyurethane foam, polyethylene foam, polyester foam and the like can be used. In this case, it is preferable to use a polyurethane foam. This is because polyurethane foam has excellent set resistance. Also, it is preferable that the flame retardant treatment is not applied to this cushion material, for example, polyurethane foam. Even if the cushion material is not subjected to the flame retardant treatment, in the fiber laminate of the present invention, the burning of the fiber laminate is suppressed by the nonwoven fabric used for the backing base fabric, and the flame retardancy of the fiber laminate is ensured. be able to. Further, since no flame retardant is added, the mass can be reduced accordingly and the productivity can be improved. Furthermore, it is excellent in terms of environmental impact.

The backing base fabric used in the fiber laminate of the present invention is a nonwoven fabric having a fiber length of 100 mm or less and short fibers containing cellulosic fibers entangled by a water jet method. By using a nonwoven fabric as the backing base fabric in this way, an excellent flame retardant effect can be exerted due to the uniform structure of the nonwoven fabric even if the basis weight of the nonwoven fabric is small.

The nonwoven fabric used in the fiber laminate of the present invention is a nonwoven fabric in which short fibers having a fiber length of 100 mm or less are entangled by a water jet method. Since the nonwoven fabric is manufactured using short fibers, it is possible to impart excellent elongation characteristics to the nonwoven fabric, unlike the case of spunbond, which is a nonwoven fabric using long fibers. In this case, as the short fibers, short fibers of 100 mm or less may be used, and preferably short fibers of 10 to 52 mm can be used. This is because, as will be described later, when different types of fibers are used, shorter fibers are easier to mix.

Since the nonwoven fabric used as the backing base fabric also has excellent elongation properties, it does not inhibit the elongation properties of the skin material even when used together with a skin material also having excellent elongation properties. Can have excellent flexibility.

The short fibers include cellulosic fibers. By using cellulosic fibers as short fibers, flame retardancy can be improved. By using the cellulosic fiber, the cellulosic fiber itself stably burns and burns while being carbonized, so that the combustion of the skin material and the cushion material can be suppressed. Therefore, in this case, a nonwoven fabric can be produced using only the cellulosic fibers. Further, it is preferable to produce a nonwoven fabric by adding synthetic fibers to cellulosic fibers. When a non-woven fabric made of a mixture of cellulosic fibers and synthetic fibers burns, the synthetic fibers that are melted become fuel, and are adhered to or absorbed by the cellulose fibers. Carbonize. Therefore, the nonwoven fabric in which the cellulose fibers and the synthetic fibers are mixed has a higher combustion suppressing effect.

As the synthetic fibers, synthetic fibers such as polyethylene terephthalate, acrylic, polyamide, acetate and the like can be used. It is also possible to use a plurality of types of synthetic fibers. In this case, it is preferable to use polyethylene terephthalate or polyamide as the synthetic fiber. This is because polyethylene terephthalate or polyamide is superior in durability to other synthetic fibers, is relatively hard to burn, and can reduce the production cost. When a nonwoven fabric is manufactured using a synthetic fiber and a cellulosic fiber, the cellulosic fiber is preferably 20 to 80% when the total mass of the cellulosic fiber and the synthetic fiber is 100%. . The non-woven fabric produced at this ratio is excellent in flame retardant effect.

The basis weight of this nonwoven fabric is 20 to 60 g / m
^2, and more preferably 30 to 60 g / m ² . This is because the workability and abrasion in the manufacturing process are excellent.

This nonwoven fabric can be prepared by a papermaking method. That is, it is possible to produce a sheet-like web by randomly laminating those obtained by dispersing short fibers in water and to entangle the short fibers with each other by a water punch. It can also be prepared by a dry method. That is, it is possible to produce a sheet-like web by randomly laminating short fibers using a card machine, and to entangle the short fibers with each other by a water punch. By performing the driving using the water punch in this manner, it is possible to impart three-dimensional entanglement to the fibers constituting the web which has been entangled two-dimensionally, and to provide the nonwoven fabric with anti-settling property and form stability. Can be.

Since three-dimensional entanglement is given by the water punch, machine oil and other impurities hardly enter the nonwoven fabric. Therefore, it does not impair the flame retardancy, and is also preferable from the viewpoint of hygiene.

Since the non-woven fabric entangled with the fibers by the water jet method is used, the elongation characteristics are excellent, and the elongation of the skin material having the excellent elongation characteristics is hardly affected.

It is preferable that the non-woven fabric is not subjected to the flame retarding treatment. Even if the flame retardant treatment is not performed, in the fiber laminate of the present invention, the burning of the fiber laminate can be suppressed by the above-described nonwoven fabric, and the flame retardancy of the fiber laminate can be ensured. Further, since no flame retardant is added, the mass can be reduced accordingly and the productivity can be improved. Furthermore, it is excellent in terms of environmental impact.

The joining between the skin material and the backing fabric, the joining between the skin material and the cushioning material, and the joining between the cushioning material and the backing fabric can be performed by an appropriate method. For example, it can be appropriately performed by a method such as adhesion, fusion, or suturing. In particular, a frame laminate in which the cushion material is joined to the skin material and the backing base fabric by heating and melting the cushion material is preferable. By not using an adhesive or the like, there is no increase in mass and no hindrance to flame retardancy.

[0040]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As described in the above embodiment, the fiber laminate of the present invention is a two-layer fiber laminate 50 composed of a skin material 10 and a backing fabric 20 as shown in FIG. Even
As shown in FIG. 2, a three-layer fiber laminate 50 including the skin material 10, the cushion material 30, and the backing fabric 20 may be used. In FIGS. 1 and 2, the same reference numerals are used for the fiber laminate and similar elements.

Hereinafter, examples of the fiber laminate of the present invention will be described in detail. Three types of fiber laminates having a three-layer structure as shown in FIG. 2 were produced as examples of the fiber laminate of the present invention.

(Example 1) As the skin material 10 of Example 1, a woven fabric A was used. This fabric A was not subjected to a flame retardant treatment. This woven fabric A was composed only of polyethylene terephthalate. The basis weight is 255 g / m ^2.

And the hardness is 10 kg / 314 m ² (JIS Z 2243
According to the Brinell Katasa test method). Back fabric 20
A non-woven fabric was used. No flame retardant treatment was applied to this nonwoven fabric. The nonwoven fabric used here was a nonwoven fabric in which short fibers composed of cellulosic fibers and polyethylene terephthalate fibers were entangled by a water jet method. Short fibers having a fiber length of 52 mm were used. The ratio of the cellulosic fiber to the polyethylene terephthalate fiber is 5%, with the total mass of both being 100%.
At 0%, the polyethylene terephthalate fiber was 50%. The thickness of this nonwoven fabric was 0.57 mm, and the apparent weight was 40 g / m ² .

The skin material 10 and the cushion material 30, and the cushion material 30 and the backing fabric 20 were joined by a frame laminating method. That is, both surfaces of the slab urethane were uniformly heated and melted by a burner, and the skin material 10 was bonded to one molten surface of the slab urethane and the backing fabric 20 was bonded to the other molten surface by pressure bonding. (Example 2) The fabric B was used as the skin material 10 of Example 2. This fabric B was not subjected to the flame-retardant treatment as in Example 1. This woven fabric B was composed only of polyethylene terephthalate. The basis weight is 200

(Example 3) As the skin material 10 of Example 3, Tricot A was used. This tricot A was not subjected to the flame-retardant treatment as in Example 1. This tricot A was composed of only polyethylene terephthalate. The basis weight was 245 g / m ² . The same cushioning material 30 and backing fabric 20 as in Example 1 were used. Similarly to Example 1, the backing fabric 20 was not subjected to the flame retardant treatment.

The bonding between the skin material 10 and the cushion material 30 and the bonding between the cushion material 30 and the backing fabric 20 were performed in the same manner as in Example 1.

(Evaluation Test) The fiber laminates of Examples 1 to 3 were evaluated for the burning rate. This evaluation test was conducted according to the United States automobile safety standard FMVSS-302.
The burning rate of the fiber laminate was measured by the method specified in (1).

As a result, Example 1 using the woven fabric A as the skin material 10 exhibited a burning rate of 71 mm / min. Example 2 using the woven fabric B as the skin material 10 was 77 mm
/ Min burning rate. Further, tricot A is applied to skin material 1
Example 3, used as 0, showed a burning rate of 75 mm / min.

Comparative Example Next, for comparison with the fiber laminates of Examples 1 to 3, a fiber laminate having a three-layer structure was also manufactured as a comparative example, and the above-described evaluation test on the burning rate was performed. . That is, the US automobile safety standard FMVSS-302
An evaluation test was performed according to the method specified in (1).

The fiber laminate of Comparative Example 1 was a three-layer fiber laminate comprising a skin material, a cushion material, and a backing fabric.
The same skin material and cushion material as in Example 1 were used for the skin material and the cushion material. That is, the woven fabric A not subjected to the flame retarding treatment was used as the skin material. Similarly, slab urethane for frame lamination was used as a cushion material. A conventional nonwoven fabric was used as the backing base fabric. This nonwoven fabric was a tricot roof made of 14d (denier) nylon yarn and had good stretchability, and the basis weight was about 20 g / m ² . No flame retardant treatment was applied to this nonwoven fabric.

The bonding between the woven fabric A and the slab urethane for frame lamination and the bonding between the slab urethane for frame lamination and the nonwoven fabric were performed in the same manner as in the example.

The fiber laminate of Comparative Example 2 was a three-layer fiber laminate composed of a skin material, a cushion material, and a backing fabric. As the skin material and the cushion material, the same skin material and cushion material as in Example 3 were used. That is, Tricot A which has not been subjected to flame retardant treatment was used as a skin material. In addition, slab urethane for frame lamination, which has not been subjected to flame retardant treatment, was used as the cushion material. The same non-woven fabric as that of Comparative Example 1 which had not been subjected to the flame retardant treatment was used as the backing fabric. The joining of the tricot A to the slab urethane for frame lamination and the joining of the slab urethane for frame lamination to the nonwoven fabric were performed in the same manner as in the example.

The test result of the fiber laminate of Comparative Example 1 was 109 mm / min. The test result of the fiber laminate of Comparative Example 2 was 97 mm / min.

(Evaluation) Examples 1, 2, and 3
Are different from each other only in the skin material, and the same material is used for the cushion material and the backing base fabric. For these examples, even if the skin material is different, 71 mm / min (Example 1),
77 mm / min (Example 2), 75 mm / min (Example 3)
Thus, the combustion speed is stable. It is understood that this is because the nonwoven fabric used in the fiber laminate of the present invention has an excellent effect of suppressing combustion even when different skin materials are used. This is apparent from comparison with the test results of Comparative Examples 1 and 2.

Comparative Example 1 and Comparative Example 2 differ only in the skin material, and use the same cushioning material and backing fabric. However, the test results of Comparative Example 1 and Comparative Example 2 were 109 m
When different skin materials such as m / min and 97 mm / min are used, there is a great difference. It is understood that this is because the conventional nonwoven fabric used for the backing base cloth does not have the effect of suppressing the burning rate as compared with the nonwoven fabric used in the examples.

Further, by comparing Example 1 with Comparative Example 1, it is clear that the nonwoven fabric used in the example has an excellent combustion suppressing effect. That is, Example 1 and Comparative Example 1 differ only in the nonwoven fabric used for the backing fabric, and the skin material and the cushion material are the same, such as woven fabric A as the skin material and slab urethane for frame lamination as the cushion material. Used. As described above, only the non-woven fabric used for the backing base fabric is different.
mm / min. This indicates that the nonwoven fabric used in Example 1 has an excellent effect of suppressing the burning rate. The same applies to the comparison between Example 3 and Comparative Example 2. That is, Example 3 and Comparative Example 2 differ only in the nonwoven fabric used for the backing fabric,
The same skin material and cushion material such as Tricot A as skin material and slab urethane for frame lamination as cushion material are used. In this case as well, only the nonwoven fabric used as the backing fabric was different.
Is 75 mm / min, and that of Comparative Example 2 is 97 mm / min. This also shows that the nonwoven fabric used in Example 3 has an excellent effect of suppressing the burning rate.

Both Example 1 and Example 3 use the same nonwoven fabric, and the fiber laminate of the present invention using the nonwoven fabric shown in Example as the backing base fabric has an excellent effect of suppressing the burning rate. Can be understood.

[0058]

The fiber laminate for vehicles according to the present invention can exhibit an excellent flame retardant effect even if the basis weight of the nonwoven fabric used as the backing fabric is small. As a result, the mass of the vehicle fiber laminate can be reduced. Also, the manufacturing cost can be reduced.

Further, since the nonwoven fabric having excellent elongation characteristics is used as the backing fabric in the vehicular fiber laminate of the present invention, the elongation characteristics of the skin material are hardly affected.

Further, the vehicle fiber laminate of the present invention exhibits an excellent combustion suppressing effect without performing flame retardant treatment.
There is no need to add a flame retardant, and it is excellent in terms of the effect on the environment.

Further, since the nonwoven fabric used in the fiber laminate for vehicles of the present invention is produced by entanglement of fibers by a water jet method, it is more sanitary than conventional fiber laminate for vehicles.
