Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fabric mainly used for a chair upholstery of a seat of a transportation system (hereinafter collectively referred to as “vehicle”) such as an aircraft, a passenger car, a long distance bus, and an automobile.
[0002]
[Prior art]
The chair seat of the vehicle seat is aesthetically pleasing and decorative as an interior material, wear resistance that can withstand long-term use, durability such as tear strength, expansion and contraction, and shape stability, and the skin adheres to it for a long time. Breathability is required so as not to give a feeling.
[0003]
[Problems to be solved by the invention]
In order to increase the breathability of fabric for chair upholstery, it is only necessary to increase the warp density and weft density. However, coarse fabric is not concealed and the seat base can be seen through, making it a body as an interior material. First, warp and wefts are misaligned and wrinkled due to expansion and contraction, resulting in lack of durability.
[0004]

[0011]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a conventional woven fabric for chair upholstery, in which 165 dtex polyester fiber yarns 21 and 22 are arranged with a warp density of 40/10 cm as warps, a pile length of 1.5 mm as an weft, and an apparent thickness ( A 3 mm diameter yarn 13 and 165 dtex polyester fiber weft yarn 20 are repeatedly knitted between warp yarns with one molding yarn and two weft yarns, and are woven with a plain weave structure. The combined weft density of the weft 20 is 180/10 cm. In this molding fabric, the warp yarns 21 and 22 and the weft yarns 20 and 21 form a base fabric, and the molding yarn 13 is configured to be locked to the warp yarns 21 and 22 by the base fabric.
[0012]
FIG. 2 illustrates a molding fabric for chair upholstery according to the present invention. Like the conventional product illustrated in FIG. 1, 165 dtex polyester fiber yarns 11 and 12 are arranged with a warp density of 40/10 cm as warps. As a weft, a mole yarn 13 having a pile length of 1.5 mm and an apparent thickness (diameter) of 3 mm is used. In this molding fabric, no weft yarn is used, only the molding yarn 13 is driven between the warps, and the weft density is 60 yarns / 10 cm. The weaving warp 11 is picked for each picking. It dives under the shaft warp 12 and floats again above the shaft warp 12.
[0013]
As is clear from the comparison between FIG. 1 and FIG. 2, in the conventional product (FIG. 1), the molding yarn is locked to the base fabric composed of the warp yarns 21 and 22 and the weft yarns 20 and 20 by the warp yarns 21 and 22. However, in the present invention (FIG. 2), the base fabric for locking the molding yarn is not formed, and the molding fabric is formed by the molding yarn 13 and the warp yarns 11 and 12. For this reason, in the molding fabric (FIG. 2) of the present invention, compared to the conventional product (FIG. 1), the weft density is coarser by the amount that the weft yarn 20 is not used, and the air permeability is increased by that amount. The number of picking (weft driving) per unit length of the mole fabric is less by the amount that the weft 20 is not driven, and as a result, the weaving efficiency is increased by a factor of 3 compared to the conventional product (FIG. 1).
[0014]
As described above, in the present invention, the weft density is coarser than that of the conventional product (FIG. 1) by the amount of not using the weft yarn 20, but the conventional product (FIG. 1) is interposed between the molding yarn 13 and the molding yarn 13. Just as the warps 21 and 22 are intertwined with the weft wefts 20 and 20, the sag warp 11 and the shaft warp 12 are intertwined. Before and after the molding yarn 13, the left and right positions are mutually changed and the upper and lower positional relationships are reversed, and the molding yarn 13 is bound to the sag warp 11 and the shaft warp 12. . For this reason, compared to the conventional product (FIG. 1) in which the warp yarns 21 and 22 are simply inverted in the vertical relationship and intertwined with the weft yarns 20 and 20 and the molding yarn 13 (FIG. 1), the molding fabric (FIG. 2) of the present invention. Then, the bonding state among the molding yarn 13, the warp warp 11 and the shaft warp 12 becomes strong, and no misalignment occurs between them, and the shape stability is excellent.
[0015]
In other words, when looking at the entangled state of two warps and two wefts that make up the basic structure of the fabric details, the conventional product (Fig. 1) has a total of four yarns of these warps and wefts in a total of four places. Although it is entangled, when it is constituted by a weave structure as in the present invention (FIG. 2), not only two warps and two wefts are entangled at four places, but also two warps are mutually The number of entanglement points is increased by that amount, entangled at a total of 6 locations, and the number of entanglement points is 1.5 times that of the conventional product (Fig. 1). It is said that the shape stability is improved due to the difficulty of the occurrence of the above. Further, in the present invention (FIG. 2), the warp warp 11 and the shaft warp 12 are not arranged in parallel like the warp yarns 21 and 22 of the conventional product (FIG. 1), but are mutually arranged between the front and rear wefts. The twisted state is obtained by changing the left and right positions and reversing the positional relationship between the upper and lower sides, reducing the bulk at the twist point 19 and widening the gap 16 between the two front and rear wefts. For this reason, even when weaving at the same weft density as the conventional product (FIG. 1), according to the present invention, the air permeability is high, the feeling of stuffiness is not given, and there is no misalignment between the warp and the weft, A fabric for chair upholstery that is excellent in wear resistance and shape stability can be obtained.
[0016]
When weft yarns are used, such as morsel yarns, chenille yarns, and flocky yarns , the decorative fibers 15 protrude from the core yarns 14 to form a core-sheath cross-sectional structure, and bulky yarns whose apparent thickness is 10 times or more the actual thickness are used. Even if the weft density is so coarse that the back side can be seen through the gaps 16 between the wefts, the gaps 16 are concealed by the decorative fibers 15 protruding from the wefts 13, so that the air permeability is 200 cm ³ / cm ^2. It can be kept to a sec or less, and the beauty of the chair upholstery is not impaired as an interior material. The “substantial thickness” mentioned here is 0.25 × π when the mass per unit length L (cm) of the weft is W (g) and the specific gravity of the fibers constituting the weft is ρ. It means the diameter D of the weft calculated by the relational expression of × D ² × L × ρ = W. The sag warp 11 and the shaft warp 12 change the left and right positions before and after each weft 13 and are turned upside down so that the weft 13 is twisted at the binding point 17. The warp 12 is strongly bound to reduce the bulk, and a dent 18 is formed on the surface of the weft at the connection point 17, and the warp 11 and the shaft warp 12 are fitted into the dent 18. There is no misalignment between the weft 13 and the weft 13, and the shape of the gap 16 between the wefts is maintained, thereby ensuring the air permeability of the fabric.
[0017]
In order to facilitate the formation of the depression 18 on the surface of the weft as described above, and to suppress the air permeability to 200 cm ³ / cm ² · sec or less, the sag warp 11 and the shaft warp 12 are compared with the weft. It is recommended that the thickness (fineness) of the weft 13 is 1.8 times or more the thickness (fineness) of the warps 11 and 12 . On the other hand , even if the kneading warp 11 and the shaft warp 12 are made thin, they are twisted at the twist point 19 between the weft 13 and the weft 13 in the same manner as the twisted yarn, so that the strength is increased. There is no loss of durability.
[0018]
If the warp density or weft density of the woven fabric is rough and the occurrence of wrinkle-like wrinkles due to expansion or contraction of the warp or weft is concerned, it is advisable to mix elastic yarn with the warp or weft. As the elastic yarn, a polyetherester elastomer elastic yarn or spandex yarn having a breaking elongation of 60% or more, an elongation rate of 30% and an elastic recovery rate of 90% or more after elongation, preferably a low melting point polyetherester It is better to use a core-sheath composite filament elastic yarn having both a heat-fusible property and a heat-shrinkable property using an elastomer as a sheath component and a high-melting-point polyether ester elastomer as a core component. It is preferable to heat-set the core-sheath composite filament elastic yarn after weaving using a system fiber.
[0019]
According to the present invention, all of the conventional fabrics for chair upholstery can be applied to a part or all of the fabric without changing the specifications such as the warp density, the weft density, the warp and weft thickness, and the number of twists. The air permeability can be increased to 16 cm ³ / cm ² · sec or more by generating, and when the weaving specifications such as the warp density and the weft density are changed, the air permeability can be further increased. In a fabric for chair-tensioned fabric with standardized fabric weight, warp density and weft density, the gap 16 between the wefts becomes large, and as a result, when the air permeability becomes 200 cm ³ / cm ² · sec or more, wefts Is thicker than the warp, preferably the thickness of the weft is at least twice the thickness of the warp, and at least the thickness of the weft is at least 1.8 times the thickness of the warp. Is used for the weft, the gap 16 is concealed by the bulky surface fiber (15), the air permeability is suppressed to 200 cm ³ / cm ² · sec or less, and the aesthetic appearance is not impaired by the gap 16 between the wefts. .
[0020]
The air permeability is set to 200 cm ³ / cm ² · sec or less so that the fabric for chair stretch fabrics, such as summer clothing fabrics, lace curtain fabrics, construction sheet fabrics, etc., does not form a mesh sheet with good ventilation. In order to maintain a moderate warmth as a fabric for the earth, to prevent the aesthetics of the fabric for the chair upholstery as an interior material from being damaged by the gap between the wefts, and also as a chair upholstery This is to prevent the durability of the steel from being impaired.
[0021]
The air permeability does not need to be 16 to 200 cm ³ / cm ² · sec over the entire surface of the fabric 25 for chair tension, and only the portion A where the skin and the body are always in contact with the seat as shown in FIG. It is not necessary to do so in a portion where the skin is hardly touched or in a portion C where the skin is hardly touched. Further, in the portion B where the skin is lightly touched, it is not necessary for all the warps 11 and 12 to form the weave 13 and the weave structure as shown in FIG. As shown, the warp yarns can be formed so as to form a textured structure. In the portion C where the skin is hardly touched, as shown in FIG. 3 by enlarging and encircled by a circle, some of the warp yarns 12 and 12 that are every other number may form a weave texture with the weft yarn 13. .
[0022]
In this way, when partially applying the woven fabric structure, the entanglement of the warp yarns 11 and 12 and the weft yarn 13 between the non-woven woven fabric portion 23 and the woven fabric tissue portion 24 such as a plain woven fabric or a twill woven fabric or between the wefts Depending on the difference in appearance due to the presence or absence of the gap 16 or the size of the gap 16 between the wefts, it is possible to express the required design and ground pattern on the fabric 25 for the chair upholstery. In particular, a new fabric for chair upholstery can be obtained.
[0023]
【The invention's effect】
As described above, according to the present invention, the fabric for chair upholstery can be kept warm as a fabric for chair upholstery without forming an airy mesh sheet like summer clothing fabric, lace curtain fabric or construction sheet. It keeps the feeling of stuffiness, has excellent shape stability and durability, does not generate hook-shaped wrinkles due to expansion and contraction during use, and is a new interior material that is new in design and efficient for fabrics that are optimal for chairs It is possible to obtain a comfortable vehicle seat.
