Description

  The present invention relates to a functional fabric. More specifically, the present invention relates to a fabric having a deodorizing performance and hardly causing wrinkles.

  One of the functions required for the fabric is deodorization performance. In particular, fabrics used for interiors of vehicles, ships, aircraft, etc. (for example, fabrics used for trim members such as vehicle seats and door linings for automobiles, etc.) are used in a closed space and have an odor attached to the fabric. However, there is a problem that it is difficult to remove the odor once attached because it is easily trapped in the space and washing and cleaning are difficult.

For this reason, deodorizing performance is imparted to a fabric by coating the fabric with a coating composition containing a deodorant. For example, Patent Document 1 discloses a fabric having deodorant properties and flame retardancy (Patent Document 1).
However, when a fabric is coated with a coating composition containing a deodorant, deodorizing performance can be imparted to the fabric, but discoloration tends to occur when hot or water is spilled on the fabric, There is a problem that even if the fabric dries, it does not return to the original color (that is, it becomes easy to cause wrinkles).

  An object of the present invention is to solve the above-described problems, and an object of the present invention is to provide a fabric that has excellent deodorizing performance and is less likely to cause wrinkles.

  As a result of repeated studies to solve the above problems, the inventors of the present invention formed a coating layer (first coating layer) containing a predetermined amount of a fluorine-based water and oil repellent agent on one side of the fabric. The present invention was completed by successfully forming the coating layer containing the deodorant (second coating layer) on top of the above problem.

That is, the fabric of the present invention has a first coating layer containing a fluorine-based water / oil repellent and a second coating layer containing a deodorant on one side (particularly the back side),

The first coating layer is present between the fabric and the second coating layer.

As described above, when one side of a polyester-based fabric is coated with a composition containing a deodorant, deodorizing properties can be imparted to the fabric, but wrinkles tend to occur. Even if a water- and oil-repellent agent is added to a coating composition containing a deodorant to form a coating layer, the wrinkle is not sufficiently improved.
On the other hand, in the present invention, the water / oil repellent coating layer and the deodorant coating layer are provided on one side of the fabric (particularly the back side of the fabric), and the water / oil repellent coating layer (first coating layer) from the fabric side. Deodorant coating layer (second coating layer) is provided in this order, and the amount of the fluorine-based water and oil repellent contained in the first coating layer is a predetermined amount, so that it has excellent deodorizing properties (deodorizing properties) In addition, the present invention has succeeded in producing a fabric that has no wrinkle.

  The second coating layer preferably further contains a flame retardant. By adding a flame retardant to the second coating layer, the flame retardancy of the fabric can be enhanced.

  Further, the cloth is preferably a cloth impregnated with a fluorine-based water and oil repellent. By impregnating the fabric with a fluorine-based water and oil repellent, high antifouling properties against oil and moisture can be imparted to the fabric.

Moreover, it is preferable that a 1st coating layer contains a flame retardant further and the binder resin contained in a said 1st coating layer is acrylic resin.
By using an acrylic resin as the binder resin (base resin) of the first coating layer, the texture of the fabric is improved, and the addition of a flame retardant to the first coating layer can increase the flame retardancy. it can.

In the present invention, the fabric impregnated with the fluorine-based water / oil repellent means a fabric in which the fluorine-based water / oil repellent is attached not only to the surface of the fabric but also to the internal fibers.
As a method for impregnating a polyester fabric with a fluorine-based water / oil repellent, an immersion treatment called a padding treatment or a dip / nip treatment can be generally used. For example, an aqueous treatment liquid containing 1.0 to 5.0% by weight, more preferably 1.5 to 3.5% by weight of a fluorine-based water / oil repellent (solid content) is prepared. Immerse in the treatment liquid (for example, 2 to 5 minutes) and squeeze it with a roller (mangle), etc., so that the treatment liquid can be contained in the entire fabric, and then dried to impregnate the fluorine-based water and oil repellent. A finished fabric can be obtained. Suitable drying conditions are, for example, 110 to 170 ° C, particularly 120 to 160 ° C and about 1 to 5 minutes.
The amount of the fluorine-based water / oil repellent that is impregnated into the fabric by this antifouling treatment can be calculated from the concentration and the drawing ratio of the fluorine-based water / oil repellent in the treatment liquid. Included in the fabric after drying is, impregnation amount of fluorine-containing water- and oil-repellent is per unit area of the ^{fabric, 2.0g / m 2 ~8.0g / m} 2 are suitable, 3.0 g / m ² ˜7.0 g / m ² is more preferable, and 4.0 g / m ^{2 to} 6.5 g / m ² is particularly preferable.

  In the present invention, a coating layer (first coating layer) containing a fluorine-based water and oil repellent agent is formed on one surface (particularly the back surface) of the base fabric that is optionally subjected to the antifouling treatment. As the fluorine-based water / oil repellent for the first coating layer, those mentioned above as the fluorine-based water / oil repellent used during the immersion treatment can be used. The same thing may be used, a different thing may be used, only 1 type may be used, or multiple types may be used together.

The content of fluorine-containing water- and oil-repellent contained in the first coating layer, per unit area of the fabric, is preferably ^{1.3g / m 2 ~5.0g / m 2} . If the amount of the fluorinated water / oil repellent is too small, it becomes easy to cause wrinkles, and if the amount of the fluorinated water / oil repellent is too large, the flame retardancy tends to decrease. More preferable content of fluorine-containing water- and oil-repellent is per unit area of a fabric, a ^{1.5g / m 2 ~4.5g / m 2} .

  The first coating layer may include one or more flame retardants. The flame retardant that can be used in the first coating layer is preferably a phosphorus flame retardant having a solubility in water at 20 ° C. of 4% (4 g / 100 g of water) or less. Examples of the phosphorus flame retardant include a flame retardant selected from the group consisting of phosphonic acid esters, phosphoric acid amides, phosphoric acid ester amides, aromatic phosphoric acid esters, halogen-containing phosphoric acid esters, and the like. . An organophosphorus flame retardant is particularly preferable. As an example of a preferable flame retardant, phosphonic acid ester flame retardant and / or melamine phosphate may be mentioned.

  In the present invention, a second coating layer containing at least one deodorant is formed on the first coating layer formed on one surface (particularly the back surface) of the fabric. As the deodorant used for the second coating layer, it is preferable to use a deodorant component supported on an inert inorganic porous particle (carrier). As described above, by supporting the deodorant component on the inorganic porous particles, it is possible to prevent the deodorant components from being in direct contact with each other or being inhibited by the presence of the flame retardant. For example, an amine compound, a metal compound or cyclodextrin may be used by supporting them on separate carriers. As the carrier, silica, silica-alumina composite or layered double hydroxide is useful.

  As the amine compound, it is preferable to use a compound having a primary amine group in the molecule, for example, a hydrazine compound particularly effective for adsorption of formaldehyde, acetaldehyde, acetic acid and the like. Examples of the hydrazine compounds include adipic acid dihydrazide, azelaic acid dihydrazide, succinic acid dihydrazide, glutaric acid dihydrazide, oxalic acid dihydrazide, superic acid dihydrazide, sebacic acid dihydrazide, dodecanedioic acid dihydrazide, pimelic acid dihydrazide, Examples include isophthalic acid dihydrazide, terephthalic acid dihydrazide, and polyacrylic acid hydrazide.

The content of deodorant agent contained in the second coating layer, per unit area of the fabric, preferably ^{5g / m 2 ~20g / m 2} , more preferably ^{7g / m 2 ~15g / m 2} , 8g / m 2 ˜13 g / m ² is particularly preferred.

Moreover, the flame retardant contained in the second coating layer is preferably substantially free of halogen. In particular, it is preferable to use a silicone surface-treated or water-insoluble one so that the functionality is not impaired by the combined use with a deodorant, especially a silicone-coated ammonium polyphosphate or metal salt of dialkylphosphinic acid. Is useful. In the metal salt of dialkylphosphinic acid, examples of the alkyl group include methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, n-pentyl and / or phenyl, and examples of the metal include aluminum and magnesium. , Calcium, titanium, zinc, tin or zirconium. Of these, particularly preferred is aluminum diethylphosphinate.
Moreover, that a flame retardant does not contain a halogen substantially means that the halogen of the grade which is an impurity and does not inhibit the effect of this invention may be contained.

The content of the flame retardant contained in the second coating layer, per unit area of the fabric, preferably ^{15g / m 2 ~45g / m 2} , more preferably ^{20g / m 2 ~40g / m 2} , 25g / m ^{2 to} 37 g / m ² is particularly preferred.

If a water / oil repellent agent is added to the second coating layer, the peel strength between the fabric and the foam sheet when the foam sheet is fixed to the fabric (see FIG. 1b) is lowered. It is better not to contain water / oil repellent substantially (the content of the water / oil repellent contained in the second coating layer is preferably less than 0.1 g / m ² per unit area of the fabric, 0 g / m ² is more preferred).

  The composition for forming the first and second coating layers according to the present invention contains a binder for adhering (fixing) a fluorine-based water / oil repellent or deodorant to a fabric. Preferred binders include polyester resins, acrylic resins, and urethane resins. When emphasizing flame retardancy, it is preferable to use a polyester resin, and when emphasizing cost and texture, it is preferable to use an acrylic resin.

As the polyester resin, acrylic resin, and urethane resin, commercially available polyester resins, acrylic resins, and urethane resins that are used as binders in ordinary coating compositions for fabrics can be used.
In particular, each binder has a good soft type. For acrylic resins, Tg = -30 ° C to -45 ° C is good. For urethane resins, the minimum film-forming temperature (MFT) is 0 ° C to 5 ° C. Is good.

Moreover, the composition for 1st and 2nd coating may contain the thickener. As the thickener, cellulose thickeners, acrylic acid thickeners, urethane associative thickeners, and the like can be used. The content of the thickener contained in the coating layer is usually about 0.3 to 5.0 g / m ² per unit area of the fabric.

  The viscosity of the first and second coating compositions is suitably about 20,000 to 70,000 mPa · s, particularly preferably about 30,000 to 55,000 mPa · s. In the present specification, the viscosity of the coating composition means that a B-type viscometer (BH type) is used at a measurement temperature of 20 ° C., rotor No. 6, rotation speed of 10 rpm, and 30 seconds after starting rotation. It means the measured viscosity.

  The first and second coating compositions can be applied to the fabric using a knife coater, comma coater, bar coater, die coater, kiss roll coater, gravure coater or the like. Moreover, the drying conditions after apply | coating the composition for 1st and 2nd coating to a fabric can be made into about 2 to 5 minutes, for example at 110-170 degreeC, especially 120-160 degreeC.

  In the fabric according to the present invention, a foam sheet may be fixed to the coating surface side (on the second coating layer) of the fabric (see FIG. 1b). An example of the foam sheet is a polyurethane foam (slab urethane or the like) having a thickness of 2.0 to 10 mm. Such a laminate composite comprising a fabric and a foam sheet is suitable for use as a skin material of a vehicle seat (usually a molded article made of a urethane cushion material) such as an automobile.

  As a method for fixing the foam sheet to one side of the fabric, for example, the surface of one side of the foam sheet is melted using a gas burner, and the one side (second coating) of the fabric on which the first and second coating layers are formed. Frame laminating process to be fused on the layer).

  Hereinafter, the present invention will be described in more detail with reference to comparative examples and examples, but the present invention is not limited to the examples.

[Example 1]
Fabrics shown in Table 1 were manufactured by coating polyester fabric dyed black with disperse dye (100% polyester: basis weight 280 g / m ² ).

  The coating composition for forming the coating layer on the polyester fabric was adjusted to have a viscosity in the range of 34,000 mPa · s to 36,000 mPa · s. A coating layer was formed on the back surface of the fabric with a knife coater.

  The water repellent used in the first coating layer and the second coating layer is a fluorine-based water / oil repellent sold under the name of NK Guard S-0545 from Nikka Chemical Co., Ltd.

  The acrylic resin used in the first coating layer is an acrylic resin sold under the name of Movinyl 7400 from Japan Coating Resin Co., Ltd. The acrylic resin used in the second coating layer is an acrylic resin sold under the name of Boncoat AB901 from DIC Corporation.

  The flame retardant used in the second coating layer is aluminum diethylphosphinate, and the deodorant is KD-211G (supporting zinc oxide on porous silica) sold by Rasa Industrial Co., Ltd., and This is Kesmon NS-240 (an amine compound supported on porous silica) sold by Toa Gosei Co., Ltd.

  The processed fabrics of Table 1 were tested for wrinkling, deodorizing performance, antifouling performance, flame retardancy, and stiffness by the following methods.

<With wrinkles>
4 ml of 80 ° C. distilled water was dropped onto the surface of the processed fabric and allowed to dry naturally for 24 hours, and then the presence or absence of wrinkles (color change) on the front and back surfaces was confirmed, and graded according to the following criteria. The case where the fabric surface is grade 4 or higher, the fabric back side is grade 4 or higher, and there is no wetting is evaluated as pass (◯).
Judgment details
・ 5th grade No color change ・ 4th grade Almost no color change ・ 3rd grade Some color change ・ 2nd grade Color change easily seen ・ 1st grade color change is remarkable

<Deodorant>
A test is performed for each of the three types of odor components, and the deodorization rate (deodorization rate) of the processed fabric for each is calculated. Specifically, a deodorizing test piece (5 cm × 5 cm processed fabric) is put into a 3 L tedlar bag with an internal volume, and a gas containing one kind of odor component to be measured (100 ppm for ammonia, 50 ppm for hydrogen sulfide). In the case of acetaldehyde, the initial concentration is adjusted to 50 ppm), and 2 L is injected into the Tedlar bag and sealed. After standing at room temperature for 4 hours, the residual concentration of odorous components is measured and the deodorization rate is calculated.

<Salad oil antifouling test>
As a test piece, about 10 × 10 cm square size is prepared from each sample (processed fabric). Place a soft wipe (Erière Pro Wipe) on the tray, place the test piece on the soft wipe with the coating side (back side) down, and drop the salad oil onto the test piece with 5 drops in 5mm or 0.05ml diameter with a dropper. To do.
In the case of a normal temperature test, the tray is placed in a gear oven 83 ° C. for 24 hours at a normal temperature, and in the case of a high temperature test, and left to stand for 24 hours. After 24 hours, the surface of the test piece is observed to see whether the salad oil dripping site is wet (no oil spots are generated), and the back and soft wipes are free of salad oil spots. A test wipe with no oil spots on the front and back surfaces of the test piece and the soft wipe placed underneath is regarded as acceptable.

<Flame retardant performance>
Tests were conducted in accordance with “Flammability of interior materials” defined in the Federal Motor-Vehicle Safety Standard (FMVSS) to determine flame retardancy.
If the test piece (processed fabric) is not ignited even if the flame is applied for 15 seconds, or if it is ignited but digested by the A mark, it is indicated as “N”. Record the burning time and burning distance and calculate the speed (number of tests is n = 3, worst results are shown in the table).

<Flexibility>
The bending resistance was measured by a so-called cantilever method.
Specifically, three test pieces each having a width of 25 mm and a length of 200 mm were sampled from the processed fabric in the vertical direction (long axis direction), and a smooth horizontal table with a 45-degree slope at one end. Above, place along the table, align one end of the test piece exactly with one end of the slope of the horizontal table, and read the position (A) of the other end of the test piece on the scale.
Next, while holding the test piece lightly with a presser plate of approximately the same size as the test piece, slide it at a speed of about 10 mm / s in the direction of the slope, and the other end when one end of the test piece touches the slope. The position (B) is read on a scale.
The bending resistance is expressed by the moving distance (A-B) of the test piece (the smaller the bending resistance value, the softer the fabric, the higher the numerical value, the harder the fabric). The table shows the average value (mm) of three measurements.

As shown in Table 1, the fabric (No. 2) subjected to only the deodorizing process had a worse evaluation result of wrinkling as compared with the fabric (No. 1) not subjected to the deodorizing process.
Even when an antifouling agent (fluorinated water and oil repellent) was added to the deodorant coating layer (No. 3), no improvement effect on wrinkles was confirmed.
Moreover, when the coating layer by an acrylic resin was provided between the fabric and the deodorant coating layer (No. 4), the surface wrinkle was improved, but the back surface wrinkle could not be prevented. . Further, when a coating layer containing a filler is provided between the fabric and the deodorant coating layer (No. 5 and No. 6), only the surface wrinkle is improved or even the surface wrinkle is improved. There wasn't.
Further, when an antifouling agent (fluorine-based water / oil repellent) is added to the deodorant coating layer and an acrylic resin coating layer is further provided between the fabric and the deodorant coating layer (No. 7), Only the surface wrinkle was improved, but the back surface wrinkle was not improved.
On the other hand, when a coating layer containing a fluorinated water / oil repellent is provided between the fabric and the deodorant coating layer, if the amount of the fluorinated water / oil repellent is small (No. 8), the surface is wrinkled. However, when the amount of the fluorine-based water / oil repellent was increased (No. 9 to No. 11), both the front and back surface wrinkles were improved.
In addition, a coating layer (first coating layer) containing a fluorine-based water / oil repellent agent is provided between the fabric and the deodorant coating layer, and the fluorine-based water / oil repellent agent is also provided to the deodorant coating layer (second coating layer). When No. 12 and No. 13 are added, if the amount of the fluorine-based water and oil repellent contained in the first layer coating layer is small, the back side wrinkle is not improved and the wrinkle improving effect is obtained. It was confirmed that it depends on the amount of the fluorine-based water and oil repellent contained in the first coating layer. In addition, when a water- and oil-repellent agent is added to the deodorant coating layer, when the laminate composite is formed by heat-sealing the slab urethane sheet to the back surface of the fabric (the surface on which the coating layer is formed), the fabric and the urethane foam A decrease in the peel strength was confirmed.
From these experiments, we improved the wrinkle by providing a coating layer (first coating layer) containing a sufficient amount of fluorinated water and oil repellent agent between the fabric and the deodorant coating layer (second coating layer). I understood that I could do it. No. No. 2 fabric and No. 2 fabric. 9-No. Since the deodorizing performance of the fabric No. 11 was exactly the same, it was confirmed that even if the first coating layer was provided, the deodorizing performance was not adversely affected (even if the first coating layer was provided, the deodorizing performance was The deodorization performance test was carried out only for some fabrics.

When the first coating layer containing the fluorine-based water / oil repellent was provided, the wrinkle could be improved, but the antifouling performance was insufficient, so before providing the first coating layer and the second coating layer on the fabric The same test as in Table 1 was conducted after impregnating the fabric with a fluorine-based water and oil repellent by the dip-nip method.
For antifouling by dip-nip, fluorine water and oil repellent sold under the name of Asahi Guard E series from Asahi Glass Co., Ltd. and fluorine type sold under the name of NK Guard S from Nikka Chemical Co., Ltd. A polyester fabric dyed black with a disperse dye in an aqueous dispersion containing 2.63 wt% (converted to solid content) of a fluorine-based water and oil repellent using a mixture of water and oil repellent (100% polyester: basis weight 280 g / m ² ) was immersed (150 ° C., 2 minutes and 30 seconds), and then squeezed with a mangle at a pressure of 3.0 kgf / cm ² (pic-up rate 60%). The amount of the fluorine-based water / oil repellent adhered to the fabric by this impregnation treatment was 4.43 g / m ² .
The results are shown in Table 2.

As shown in Table 2, by impregnating the fabric with a fluorine-based water and oil repellent, the antifouling performance in the normal temperature test was improved in all cases. Further, when the amount of the fluorine-based water / oil repellent contained in the first coating layer per unit area of the fabric was 1.3 g / m ² or more, the antifouling performance at 83 ° C. reached the acceptable level.
However, even if the dip-nip antifouling treatment is performed, the same tendency as that when the dip-nip antifouling treatment is not observed is observed, and a first coating layer containing a fluorine-based water / oil repellent must be provided. It was confirmed that the wrinkle is not improved.
Specifically, like the results in Table 1, the fabric (No. 15) subjected to only the deodorizing process had a worse evaluation result of wrinkling as compared with the fabric (No. 14) not subjected to the deodorizing process.
Further, even when an antifouling agent (fluorinated water and oil repellent) was added to the deodorant coating layer (No. 16), the wrinkle was not improved.
In addition, when a coating layer made of an acrylic resin was provided between the fabric and the deodorant coating layer (No. 17), the surface wrinkle was improved, but the back surface wrinkle could not be prevented. . Further, when a coating layer containing a filler was provided between the fabric and the deodorant coating layer, the surface wrinkle was improved, but the back surface wrinkle was not improved (No. 18 and No. 19). .
Further, when an antifouling agent (fluorine-based water and oil repellent) is added to the deodorant coating layer, and an acrylic resin coating layer is further provided between the fabric and the deodorant coating layer (No. 20), Only the surface wrinkle was improved, but the back surface wrinkle was not improved.
On the other hand, when a coating layer containing a fluorinated water and oil repellent is provided between the fabric and the deodorant coating layer, if the amount of the fluorinated water and oil repellent is small (No. 21), the surface wrinkles However, when the amount of the fluorine-based water / oil repellent was increased (No. 22 to No. 24), both the wrinkles on the front surface and the back surface were improved.
In addition, a coating layer (first coating layer) containing a fluorine-based water / oil repellent agent is provided between the fabric and the deodorant coating layer, and the fluorine-based water / oil repellent agent is also provided to the deodorant coating layer (second coating layer). When No. 25 and No. 26 are added, if the amount of the fluorine-based water / oil repellent contained in the first layer coating layer is small, the back side wrinkle is not improved and the wrinkle improving effect is obtained. It was confirmed that it depends on the amount of the fluorine-based water / oil repellent contained in the first coating layer. When a water- and oil-repellent agent is added to the deodorant coating layer, the fabric and urethane foam are formed when a laminated composite is formed by heat-sealing a slab urethane sheet to the back surface of the fabric (the surface on which the coating layer is formed). A decrease in the peel strength was confirmed.
From these experiments, when the dip-nip antifouling treatment is applied to the fabric, the antifouling performance at room temperature can be improved, but the fabric can not be improved in the wrinkle, and the fabric and the deodorizing coating layer can be improved. By providing a coating layer (first coating layer) containing a sufficient amount of a fluorinated water and oil repellent agent between the (second coating layer), it is possible to improve wrinkles and antifouling performance at 83 ° C. I understood.

  As described above, it has been found that by providing a coating layer (first coating layer) containing a fluorine-based water and oil repellent agent between the fabric and the deodorant coating layer (second coating layer), the wrinkle can be improved. By providing the first coating layer, it was observed that the flame retardancy tends to decrease. For this reason, in order to improve the flame retardant effect while maintaining the effect of improving wrinkles, the base resin of the first coating composition is changed from an acrylic resin to a polyester resin having a higher flame resistance. The same test was performed on the manufactured fabric and the processed fabric manufactured by adding a flame retardant to the first coating composition.

No. in Table 3 27-No. The polyester resin used in the 30th first coating layer is a polyester resin sold under the name of Plus Coat Z-880 from Kyoyo Chemical Industry Co., Ltd. No. in Table 3 31 and no. The flame retardant used in the first coating layer of 32 is a phosphonate ester flame retardant (20 ° C.) sold by melamine phosphate (manufactured by Shin-Nakamura Chemical Co., Ltd.) and Shinba Co., Ltd. under the name SY-TC1. In water (4.0% or less) in water (active ingredient weight ratio 1: 1).
The results are shown in Table 3.

As shown in Table 3, when the base resin of the first coating layer was changed to a polyester resin, the flame retardancy was “N” or 101 mm / min or less (No. 27 to No. 30). However, when a polyester-based resin was used, the numerical value of bending resistance increased and the fabric became hard. On the other hand, when the base resin of the first coating layer is an acrylic resin and a flame retardant is contained, a fabric having high flame retardancy, low stiffness and softness and good touch is obtained. I was able to.
In any case, the effect of reducing wrinkles could be maintained.
From these results, when the flame resistance performance is demanded for the fabric in addition to the deodorizing performance and low wrinkle resistance, a polyester resin is used as the base resin of the first coating layer, or the first coating layer is difficult. When it is effective to add a flame retardant, and when a texture (softness) is desired for the fabric, an acrylic resin is used as the base resin of the first coating layer, and a flame retardant is added to the first coating layer. It turned out to be preferable.

  ADVANTAGE OF THE INVENTION According to this invention, it can provide the fabric which has high deodorizing performance and does not produce wrinkles easily. For this reason, the fabric of the present invention is suitable for use as a fabric for interiors of vehicles such as automobiles, which can easily smell odors and is not easily washed or cleaned even if a drink or the like is spilled.
