Description

[Technical Field]

[0001] The present invention relates to an anti-static fabric for automobiles that has excellent static elimination properties and, when used as interior fabric for automobiles (for example, seat upholstery fabric), removes electric charge accumulated on the vehicle body and tires, streamlines the airflow around the vehicle body, and exhibits an effect of improving steering stability. [Background technology]

[0002] Various methods have been considered to prevent the accumulation of static electricity in fabrics. Furthermore, the required antistatic properties (static resistance) differ depending on the application of the fabric, and methods are being considered to meet these requirements. For example, for clothing, wash durability is important, while for fabrics used in chairs and sofas, friction durability is more important than wash durability. And for fabrics used as upholstery for seats in automobiles, the surface of the fabric is prone to wear, so maintaining antistatic performance after wear is important.

[0003] For fabrics used in vehicle interiors (mainly polyester fabrics), a known technique involves weaving conductive fibers into the base fabric and coating the back surface of the base fabric with a backing agent containing conductive carbon in order to obtain durable antistatic properties. However, while this method can improve the durability of the antistatic properties, it has drawbacks such as high costs associated with the antistatic function, deterioration of surface properties due to the conductive carbon backing on the back surface (decreased elasticity, increased rigidity, etc.), and inferior design aesthetics.

[0004] On the other hand, methods for imparting antistatic properties to fabrics by applying chemicals to the fibers as a post-processing step are also being considered. For example, Patent Document 1 below discloses a method for antistatic processing of synthetic fibers, characterized by applying an aqueous solution containing polyethylene glycol diamine and polyethylene glycol diglycidyl ether in a specific molar ratio to the synthetic fibers, treating them with saturated steam without drying, and then washing them. In addition, methods for applying hydrophilic processing agents (guanidine-based agents or ester-based agents) to fabrics as a post-processing step using methods such as the Dip-Nip method or spray method are also being considered. However, this type of processing presents a problem: the chemicals tend to wear off easily, making it extremely difficult to maintain the antistatic properties required for interior fabrics such as those used in automobiles.

[0005] As shown in Patent Document 2, the applicant has proposed a fabric that has static electricity removal properties and can improve the steering and driving stability of an automobile. Specifically, the invention discloses a static electricity-removing fabric obtained by dipping a positively charged polyester fiber fabric into a mixed solution containing amorphous silica and a polyester binder and drying it, then dipping it into a mixed solution containing a fluorine-based water-repellent and oil-repellent agent and drying it, and finally applying a mixed solution containing a urethane resin binder, a flame retardant and a deodorant to the back surface. In this automotive static electricity-removing fabric, inorganic particles with a fluorine-based resin attached are fixed to the surface, meaning that the fluorine-based water-repellent and oil-repellent groups of the fluorine-based resin are located on the outermost surface of the fabric. Therefore, the outermost surface is negatively charged. The fabric described in Patent Document 2, when used as the upholstery fabric for automobile seats, can remove positive charges generated during driving and positive charges generated by occupants (charges after wear) with the negative charges on the surface of the fabric. In other words, it exhibits antistatic properties even after wear, and as a result, steering and driving stability can be improved. [Prior art documents] [Patent Documents]

[0007] However, the fabric described in Patent Document 2 uses a fluoropolymer resin that is difficult to decompose in nature or in the human body, and in recent years, there has been a demand for fabrics using non-fluoropolymer resins due to environmental concerns. The present invention aims to meet such demands and to provide a fabric (particularly a seat upholstery fabric for automobiles, etc.) using a non-fluorine-based water repellent that can improve the steering and driving stability of automobiles through its excellent static electricity removal performance. [Means for solving the problem]

[0008] The present invention relates to an automotive antistatic fabric that has an antistatic function and is capable of improving the steering and driving stability of an automobile, and comprises a base material made of a positively charged polyester fiber fabric, the base material is provided with a negatively charged non-fluorine water-repellent resin, the base material is provided with a binder resin containing aluminum hydroxide particles, the non-fluorine water-repellent resin is exposed on at least a portion of the outermost surface of the base material, the non-fluorine water-repellent resin contains at least a silicone resin, and is characterized in that the Si intensity determined by X-ray fluorescence analysis is 0.05 cps / μA or higher. The present invention relates to an antistatic fabric for automobiles, preferably one in which the non-fluorine-based water-repellent resin is attached to the fibers of the base material. In the present invention, "attached to fibers" refers to both a state in which the non-fluorine-based water-repellent resin is scattered throughout the fibers (on the fiber surface or in the gaps between fibers) of at least a predetermined thickness of the fabric, and a state in which the fabric includes fibers coated with the non-fluorine-based water-repellent resin. In the present invention, an antistatic fabric for automobiles is preferably provided in which the non-fluorine-based water-repellent resin is provided as a layer covering the surface of the substrate.

[0009] In the present invention, an antistatic fabric for automobiles is preferably one in which the binder resin containing the aluminum hydroxide particles is attached to the fibers of the base material. In the present invention, an antistatic fabric for automobiles is preferably provided in which the binder resin containing the aluminum hydroxide particles is provided as a layer covering the back surface of the base material. In the present invention, an antistatic fabric for automobiles is preferably provided in which the binder resin containing aluminum hydroxide particles is attached to the fibers of the base material and is provided as a layer covering the back surface of the base material.

[Effects of the Invention]

[0010] The antistatic fabric for automobiles of the present invention possesses excellent antistatic properties, particularly even after wear, and when used for vehicle interiors, it is possible to obtain durable antistatic properties within the vehicle.

[Brief explanation of the drawing]

[0011] [Figure 1] Figures 1a to 1e are schematic diagrams showing the layer structure of the first to fifth embodiments of the antistatic fabric for automobiles of the present invention. [Modes for carrying out the invention]

[0012] Next, embodiments of the antistatic fabric for automobiles according to the present invention will be described with reference to the drawings. However, the present invention is not limited to these embodiments.

[0013] "Automotive static-dissipating fabric 1 (first embodiment)" The first embodiment of the present invention, an automotive static-dissipating fabric 1, as shown in Figure 1a, includes a base material 10 containing a positively charged polyester fiber fabric, to which a negatively charged non-fluorine water-repellent resin is attached, and a back surface coating layer 11 made of a binder resin containing aluminum hydroxide particles is provided on the back surface of the base material. Therefore, the non-fluorine water-repellent resin is exposed on at least a portion of the outermost surface 10a of the base material 10. The non-fluorine water-repellent resin contains at least a silicone resin, and the Si intensity determined by X-ray fluorescence analysis based on the silicone resin is 0.05 cps / μA or higher.

[0014] "Base material 10" The polyester fiber fabric that constitutes the base material 10 means a fabric containing highly flame-retardant polyester fibers, and may be woven, knitted, or nonwoven fabrics made solely of polyester fibers, as well as blended fabrics or knitted fabrics that use polyester fibers in combination with other fibers (natural fibers such as cotton and wool, or chemical fibers such as polyamide, rayon, and acrylic), or synthetic leather (artificial leather) made of polyester. The proportion of polyester fibers in the polyester fiber fabric is preferably 60% by weight or more, more preferably 70% by weight or more, particularly preferably 80% by weight or more, and even more preferably 90% by weight or more. The weight of the polyester fiber fabric is 100g / m 2 ~800g / m 2 The preferred lower limit is 150 g / m². 2 The above is true, and the preferred upper limit is 600 g / m². 2 The following, in particular, 500g / m 2 The following applies: The thickness of the polyester fiber fabric is 0.5 mm to 1.6 mm. The preferred lower limit is 0.7 mm or more, and the preferred upper limit is 1.3 mm or less. The base material 10 may be a laminate of polyester fiber fabric and other fabrics, or it may be a urethane laminate structure.

[0015] On the base material 10, a non-fluorine-based water-repellent resin is adhered throughout. Specifically, the non-fluorine-based water-repellent resin is dotted (dispersed and fixed) on the fiber surfaces of the entire base material and in the gaps between the fibers. Since this base material 10 is provided with a non-fluorine-based water-repellent resin that is charged negatively as a whole, it can stably remove the positive charges generated by abrasion. The non-fluorine-based water-repellent resin contains at least a silicone-based resin. As the non-fluorine-based resin, in addition to the silicone-based resin, it preferably contains at least one selected from urethane-based resins, ester-based resins, acrylic-based resins, hydrocarbon-based resins such as polypropylene-based resins and polyethylene-based resins, and vinyl chloride-based resins, and particularly preferably contains a urethane-based resin.

[0016] The amount of the silicone-based resin in the non-fluorine-based water-repellent resin appears as the Si intensity by X-ray fluorescence analysis. The Si intensity by X-ray fluorescence analysis of the antistatic fabric 1 for automobiles is 0.05 cps / μA to 0.30 cps / μA. The preferable lower limit is 0.07 cps / μA or more, particularly 0.10 cps / μA or more, and the preferable upper limit is 0.20 cps / μA or less, particularly 0.15 cps / μA or less. The fixing amount (dry weight) of the non-fluorine-based water-repellent resin is 1.0 g / m 2 ~3.0 g / m 2 per unit area of the polyester fiber fabric 1. The preferable lower limit is 1.2 g / m 2 or more, particularly 1.4 g / m 2 or more, and the preferable upper limit is 2.5 g / m 2 or less, particularly 2.0 g / m 2 or less.

[0017] One method for discontinuously attaching a non-fluorinated water-repellent resin to the entire fiber of such a base material 10 is to prepare a low-viscosity (e.g., 1000 mPa·s or less, preferably 100 mPa·s or less) non-fluorinated water-repellent agent by dissolving a non-fluorinated water-repellent resin containing a silicone-based resin, impregnate (dip) the polyester fiber fabric with this non-fluorinated water-repellent agent, and then dry it. As a result, the non-fluorinated water-repellent resin is discontinuously attached to the surface of the fibers and the gaps between the fibers throughout the entire fabric. Furthermore, the non-fluorinated water-repellent resin may be continuously attached (coated) to at least some or all of the fibers constituting the base material 10. In this case, a polyester fiber fabric may be formed using fibers that have been pre-coated with a non-fluorinated water-repellent resin, or a non-fluorinated water-repellent agent having a predetermined viscosity may be applied or impregnated onto the polyester fiber fabric.

[0018] "Backside coating layer 11" The back coating layer 11 is composed of a binder resin containing aluminum hydroxide particles and is provided on the back surface of the base material 10. In this automotive antistatic fabric 1, the aluminum hydroxide particles are not present within the base material 10 but only in the back coating layer 11 of the base material 10. The average particle size of the aluminum hydroxide particles is 10 μm or less, preferably 7 μm or less, particularly preferably 5 μm or less, and most preferably 3 μm or less. The amount of aluminum hydroxide particles adhering to the surface is 0.5 g / m² per unit area. 2 ~50g / m 2 The preferred lower limit is 1.0 g / m². 2 More preferably 5.0 g / m 2 In particular, 10.0 g / m² is preferred. 2 In summary, the most preferred value is 15.0 g / m². 2 The above is true, and the preferred upper limit is 25 g / m². 2 The following applies:

[0019] The binder resin used to form the back coating layer 11 can be at least one selected from polyester resins, urethane resins, and acrylic resins. For example, commercially available polyester resins, acrylic resins, and urethane resins used as binders in general fabric coating compositions can be used. When flame retardancy is important for automotive antistatic fabrics, it is preferable to use a polyester resin as the binder resin, while when cost and texture are important, it is preferable to use an acrylic resin.

[0020] The amount of binder resin fixed to the back coating layer 11 (dry weight) is 0.2 g / m² per unit area. 2 ~50g / m 2 The preferred lower limit is 1.0 g / m². 2 In particular, 1.5 g / m 2 The above is true, and the preferred upper limit is 30 g / m². 2 The following, in particular, is 20g / m 2 The following applies: Furthermore, the amount of aluminum hydroxide particles adhering to the binder resin adhering amount X (Y / X) is 0.5 to 5 times or less. The preferred lower limit is 0.8 times or more, particularly 1.0 times or more, and the preferred upper limit is 4 times or less, particularly 3.5 times or less.

[0021] The formation of such a back coating layer 11 is generally achieved by preparing a binder resin solution with a predetermined viscosity or higher (for example, 1,000 mPa·s or higher, preferably 5,000 mPa·s or higher, particularly preferably 7,000 mPa, and 100,000 mPa·s or lower) in which the aforementioned aluminum hydroxide is dispersed, applying this resin solution to the back surface of the polyester fiber fabric 1, and then drying it. In this case, the application method is not particularly limited, and gravure roll processing, roll coater processing, etc., can be used.

[0022] The back coating layer 11 may contain additives other than resin, such as deodorants and flame retardants. As a deodorant, it is preferable to use one in which the deodorant component is supported on inert inorganic porous particles (carrier). By supporting the deodorant component on inorganic porous particles in this way, it is possible to prevent the deodorant components from coming into direct contact with each other and to prevent them from being inhibited by the presence of flame retardants. Preferred deodorizing components include, for example, amine compounds, metal compounds, or cyclodextrins, and preferred inorganic porous particles (carriers) include silica, silica-alumina composites, or layered double hydroxides.

[0023] As the amine-based compound for deodorizing, it is preferable to use a compound having a primary amine group in its molecule, such as a hydrazine-based compound that is particularly effective in adsorbing formaldehyde, acetaldehyde, acetic acid, etc. In particular, examples of hydrazine compounds include adipic acid dihydrazide, azelaic acid dihydrazide, succinic acid dihydrazide, glutaric acid dihydrazide, oxalic acid dihydrazide, superiric acid dihydrazide, sebacate acid dihydrazide, dodecanediic acid dihydrazide, pimelic acid dihydrazide, malonic acid dihydrazide, isophthalic acid dihydrazide, terephthalic acid dihydrazide, and polyacrylate hydrazide. Examples of metal compounds used as deodorizing components include zinc or copper-containing metal compounds that exhibit deodorizing effects against the odors of hydrogen sulfide and mercaptans, such as zinc or copper oxides, hydroxides, chlorides, sulfates, acetates, and citrates, with zinc silicate and zinc oxide being particularly useful.

[0024] In the present invention, the degree of "deodorizing properties" is preferably such that the deodorization rate (deodor reduction rate) after 4 hours for ammonia, hydrogen sulfide, and acetaldehyde is 80% or more (more preferably 85% or more, and even more preferably 90% or more). In particular, a fabric is preferred in which the deodorization rate after 4 hours for ammonia and hydrogen sulfide is 90% or more (especially 95% or more), and the deodorization rate after 4 hours for acetaldehyde is 85% or more (especially 90% or more). The amount of deodorant contained in the second layer 30 is 5 g / m² per unit area of ​​the polyester fiber fabric 1. 2 ~20g / m 2 The following applies: The preferred lower limit is 6 g / m². 2 In particular, 7g / m 2 The above is true, and the preferred upper limit is 15 g / m². 2 The following, in particular, 10g / m 2 The following applies:

[0025] The flame retardant contained in the back coating layer 11 is preferably substantially halogen-free and preferably a phosphorus-based flame retardant. In particular, to prevent its functionality from being impaired when used in combination with a deodorant, it is preferable to use one that is surface-treated with silicone or is poorly soluble in water, and silicone-coated ammonium polyphosphate or dialkylphosphinate metal salts are particularly useful. Examples of alkyl groups in the dialkylphosphinate metal salt include methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, n-pentyl and / or phenyl, and examples of metals include aluminum, magnesium, calcium, titanium, zinc, tin or zirconium. Of these, aluminum diethylphosphinate is particularly preferred. The statement that a flame retardant is "substantially halogen-free" means that it may contain halogens in the form of impurities, but only to an extent that does not hinder the effects of the present invention. The flame retardant content in the second layer 30 is 0.5 g / m² per unit area of ​​the polyester fiber fabric 1. 2 ~30g / m 2 The following applies. The preferred lower limit is 1.0 g / m². 2 In particular, 1.2 g / m 2The above is true, and the preferred upper limit is 25 g / m². 2 More preferably 22 g / m 2 The following, in particular, is 20g / m 2 The following applies: The amount of flame retardant fixed relative to the amount of binder resin fixed is 0.5 to 5 times. The preferred lower limit is 0.7 times or more, particularly 0.8 times or more, and the preferred upper limit is 3 times or less, particularly 2.5 times or less.

[0026] The flame retardancy of automotive antistatic fabrics is preferably determined by testing them in accordance with the "flammability of interior materials" specified in the U.S. Federal Motor-Vehicle Safety Standard (FMVSS). Specifically, it is preferable that the fabric (test piece) does not ignite when a flame is applied to it for 15 seconds, or that it ignites but extinguishes before reaching the A mark (start line for combustion rate measurement), resulting in a rating of "N". Alternatively, the fabric ignites when a flame is applied to it, but after the flame crosses the A mark, the combustion rate is 101 mm / min or less. Fabrics that achieve a rating of "N" in the above evaluation are particularly preferred.

[0027] The antistatic fabric for automobiles of the present invention becomes negatively charged after its surface is rubbed five times with a cotton cloth, neutralizing positive charges generated from the vehicle interior and people. The negative charge potential is preferably -10V or less, and more preferably -100V or less. Furthermore, it is preferable that the initial charge level before friction is negative.

[0028] "Automotive static-dissipating fabric 2 (second embodiment)" The second embodiment of the present invention, the automotive antistatic fabric 2, as shown in Figure 1b, includes a base material 20 containing a positively charged polyester fiber fabric, and the fibers of the base material 20 are provided with a binder resin containing aluminum hydroxide particles and a negatively charged non-fluorine water-repellent resin in that order. Therefore, in the automotive antistatic fabric 2, the non-fluorine water-repellent resin is exposed on at least a portion of the outermost surface 20a. Furthermore, the Si intensity of the automotive antistatic fabric 2 as determined by X-ray fluorescence analysis is 0.05 cps / μA or higher. Furthermore, the polyester fiber fabric constituting the base material 20 of the automotive antistatic fabric 2 is substantially the same as that of the automotive antistatic fabric 1.

[0029] The substrate 20 has a binder resin containing aluminum hydroxide particles attached to its entire surface, and a non-fluorine-based water-repellent resin attached to the entire surface thereon. More specifically, the binder resin containing aluminum hydroxide particles is scattered (dispersed and fixed) throughout the fibers of the substrate 20 and in the gaps between the fibers, and the non-fluorine-based water-repellent resin is scattered (dispersed and fixed) on top of that.

[0030] The average particle size of the aluminum hydroxide particles attached to the substrate 20 is 10 μm or less, preferably 7 μm or less, particularly preferably 5 μm or less, and most preferably 3 μm or less. The amount of aluminum hydroxide particles fixed to the substrate 20 is 0.5 g / m² per unit area. 2 ~2.2g / m 2 The preferred lower limit is 0.7 g / m². 2 More preferably 0.8 g / m 2 In particular, 0.9 g / m² is preferred. 2 In summary, the most preferred amount is 1.0 g / m². 2 The above is true, and the preferred upper limit is 2.1 g / m 2 The following, in particular, is 2.0 g / m 2 The following is true: When aluminum hydroxide is attached to the entire fiber of the substrate 20, if the amount of aluminum hydroxide attached increases, whitening of the substrate is more likely to occur. The binder resin can be at least one selected from polyester resins, urethane resins, and acrylic resins. For example, commercially available polyester resins, acrylic resins, and urethane resins used as binders in general fabric coating compositions can be used. When flame retardancy is important for automotive antistatic fabrics, it is preferable to use a polyester resin as the binder resin, while when cost and texture are important, it is preferable to use an acrylic resin. The amount of binder resin fixed to the substrate 20 (dry weight) is 0.1 g / m² per unit area.2 ~1.0g / m 2 The preferred lower limit is 0.2 g / m². 2 In particular, 0.3 g / m 2 Therefore, the preferred upper limit is 0.8 g / m 2 The following applies: Furthermore, the amount of aluminum hydroxide particles fixed Y (Y / X) relative to the amount of binder resin fixed X is 1 to 5 times. The preferred lower limit is 1.5 times or more, particularly preferred 2.0 times or more, the preferred upper limit is 4.5 times or less, particularly preferred 4 times or less.

[0031] The base material 20 is obtained by attaching a binder resin containing aluminum hydroxide particles to a polyester resin fabric, and then attaching a non-fluorine-based water-repellent resin to it. One method for attaching a binder resin containing aluminum hydroxide particles to this polyester resin fabric is to prepare a low-viscosity binder resin solution (for example, 1000 mPa·s or less, preferably 100 mPa·s or less) in which the aforementioned aluminum hydroxide is dispersed, impregnate (dip) the polyester fiber fabric with this resin solution, and then dry it. The method for applying the non-fluorinated water-repellent resin is substantially the same as in the first embodiment described above, by dipping with a low-viscosity non-fluorinated water-repellent agent. Furthermore, the binder resin containing aluminum hydroxide particles and / or the non-fluorine-based water-repellent resin may be continuously attached (coated) to at least some or all of the fibers constituting the base material 10.

[0032] "Automotive static-dissipating fabric 3 (third embodiment)" The third embodiment of the present invention, the automotive antistatic fabric 3, as shown in Figure 1c, includes a base material 30 containing a positively charged polyester fiber fabric, on which the fibers of the base material 30 are sequentially coated with a binder resin containing aluminum hydroxide particles and a negatively charged non-fluorine water-repellent resin, and a back surface coating layer 31 made of a binder resin containing aluminum hydroxide particles is provided on the back surface of the base material. Therefore, in the automotive antistatic fabric 3, the non-fluorine water-repellent resin is exposed on at least a portion of the outermost surface 30a. Furthermore, the Si intensity of the automotive antistatic fabric 3 as determined by X-ray fluorescence analysis is 0.05 cps / μA or higher. Furthermore, the base material 30 of the automotive antistatic fabric 3 is substantially the base material 20 of the automotive antistatic fabric 2, with the back surface coating layer 11 of the automotive antistatic fabric 1 provided on it. In this automotive antistatic fabric 3, a binder resin containing aluminum hydroxide is provided within the base material 30 and in the back coating layer 31. The total amount of aluminum hydroxide particles fixed is 0.5 g / m² per unit area. 2 ~50g / m 2 The preferred lower limit is 1.0 g / m². 2 More preferably 5.0 g / m 2 In particular, 10.0 g / m² is preferred. 2 In summary, the most preferred value is 15.0 g / m². 2 The above is true, and the preferred upper limit is 25 g / m². 2 The following applies:

[0033] "Automotive static-dissipating fabric 4 (fourth embodiment)" The fourth embodiment of the present invention, the automotive antistatic fabric 4, as shown in Figure 1d, includes a base material 40 containing a positively charged polyester fiber fabric, a surface coating layer 42 containing a non-fluorine-based water-repellent resin provided on the surface of the base material 40, and a binder resin containing aluminum hydroxide particles provided on the fibers of the base material 40. In other words, the automotive antistatic fabric 4 has the non-fluorine-based water-repellent resin exposed from the outermost surface (surface coating layer 42). Furthermore, the Si intensity of the automotive antistatic fabric 3, as determined by X-ray fluorescence analysis, is 0.05 cps / μA or higher. Note that the binder resin containing aluminum hydroxide particles attached to the fibers of the base material 40 is substantially the same as that of the automotive antistatic fabric 2 of the second embodiment before the attachment of the non-fluorine-based water-repellent resin.

[0034] The non-fluorinated water-repellent resin of the surface coating layer 42 contains at least a silicone resin. The non-fluorinated resin preferably contains at least one selected from silicone resins, urethane resins, ester resins, acrylic resins, hydrocarbon resins such as polypropylene resins and polyethylene resins, and vinyl chloride resins, with a particular preference for containing a urethane resin. The amount of silicone resin in the surface coating layer 42 is expressed as Si intensity by X-ray fluorescence analysis. The Si intensity of the automotive antistatic fabric 4 by X-ray fluorescence analysis is 0.05 cps / μA to 0.30 cps / μA. The preferred lower limit is 0.07 cps / μA or higher, particularly 0.10 cps / μA, and the preferred upper limit is 0.20 cps / μA or lower, particularly 0.15 cps / μA or lower. The amount of surface coating layer 42 (non-fluorine-based water-repellent resin) fixed (dry weight) is 0.2 g / m² per unit area of ​​polyester fiber fabric 1. 2 ~30g / m 2 The preferred lower limit is 1.0 g / m². 2 In particular, 1.5 g / m 2 The above is true, and the preferred upper limit is 20 g / m². 2 The following applies:

[0035] The formation of such a surface coating layer 42 can be achieved by preparing a non-fluorinated water-repellent agent with a predetermined viscosity or higher (for example, 500 mPa·s or higher, preferably 5,000 mPa·s or higher, particularly preferably 7,000 mPa, and 100,000 mPa·s or lower) by dissolving a non-fluorinated water-repellent resin containing a silicone resin, applying this non-fluorinated water-repellent agent to the surface of a polyester fiber fabric, and then drying it. This application method is not particularly limited, and gravure roll processing, roll coater processing, etc., can be used. The base material 40 of the automotive antistatic fabric 4 is coated with a polyester resin containing aluminum hydroxide, but a non-fluorine-based water-repellent resin may also be attached, as is the case with the base material 20 of the automotive antistatic fabric 2 and the base material 30 of the automotive antistatic fabric 3.

[0036] "Automotive static-dissipating fabric 5 (Fifth embodiment)" The fifth embodiment of the present invention, an automotive antistatic fabric 5, as shown in Figure 1e, includes a base material 50 containing a positively charged polyester fiber fabric, a surface coating layer 52 containing a non-fluorine-based water-repellent resin provided on the surface of the base material 50, and a back coating layer 51 made of a binder resin containing aluminum hydroxide particles provided on the back surface of the base material 50. In other words, the automotive antistatic fabric 5 has the non-fluorine-based water-repellent resin exposed from the outermost surface (surface coating layer 52). Furthermore, the Si intensity of the automotive antistatic fabric 5 as determined by X-ray fluorescence analysis is 0.05 cps / μA or higher. Note that the surface coating layer 52 is substantially the same as the surface coating layer 42 of the automotive antistatic fabric 4 of the fourth embodiment, and the back coating layer 51 is substantially the same as the back coating layer 11 of the automotive antistatic fabric 1 of the first embodiment. Furthermore, although the base material 50 of the automotive antistatic fabric 5 does not have a non-fluorine-based water-repellent resin and a polyester resin containing aluminum hydroxide attached to the fibers, a non-fluorine-based water-repellent resin and / or a polyester resin containing aluminum hydroxide may be attached.

[0037] As embodiments of the present invention, antistatic fabrics for automobiles 1 to antistatic fabrics for automobiles 5 have been described so far, but other functional layers may be provided on these fabrics. Examples of such functional layers include, for example, urethane laminate layers.

Example

[0038] Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples. First, the measurement methods and test methods of the physical property values of the examples are shown below.

[0039] <Charge potential of fabric> For the charge potential of each fabric, a test piece with a size of 150 mm in width and 150 mm in length and a cotton canvas with a size of 20 mm in width and 100 mm in length were prepared. After laying a urethane foam with a thickness of 10 mm on the back surface of the test piece, the cotton canvas was placed against the finger and the surface of the test piece was rubbed 5 times back and forth. The charge potential of the rubbed part was measured using an electrostatic measuring instrument ("SK-H050" manufactured by Keyence Corporation).
