Description

  The present invention relates to a vehicle interior material fabric having deodorant performance.

  Car interior spaces such as automobiles and trains are closed spaces that tend to smell. Therefore, a fabric used as a vehicle interior material such as a seat sheet material or a ceiling material is required to have a deodorizing performance against various odors such as a living odor and a tobacco odor. Here, there are ammonia, trimethylamine, acetic acid, hydrogen sulfide and the like as malodorous components of living odor, and as malodorous components of tobacco odor, formaldehyde, propanal (that is, propionaldehyde), butanal (that is, butyraldehyde), There are acetic acid and hydrogen sulfide. In recent years, with the increase in pet enthusiasts, deodorization performance against pet odor has been strongly demanded. Here, examples of malodorous components of pet odors include acetaldehyde, isovaleraldehyde, acetic acid, and isovaleric acid.

  For example, in Patent Document 1, a polyester fiber is used to select a compound selected from a hydrazine derivative group in order to produce a deodorant fiber that is effective against malodorous components including aldehydes and durable against washing. A method of imparting to a class is disclosed. Patent Document 1 further expands the range of malodorous components that can be improved in durability by using a binder resin in combination, and deodorizing by using an adsorbent inorganic substance in combination. It is described that the effect can be enhanced. However, the deodorizing effect on malodorous components other than aldehydes was insufficient.

  In order to exert a deodorizing effect on a wide range of malodorous components, it is conceivable to use a plurality of deodorizers in combination. However, if a deodorant is blended carelessly, the original deodorizing effect may not be exhibited due to the reaction between the deodorants, and a comprehensive effect cannot be expected.

  By the way, examples of a method for applying a treatment liquid containing a deodorant to a fabric include an immersion method, a padding method, a coating method, and a spray method. Of these, the padding method is preferably employed from the viewpoint of the uniformity of the resulting fabric. However, when the deodorant is applied to the entire fabric by the padding method, the texture of the fabric becomes coarse or feels to the touch. There was a problem of being rough. Moreover, whitening (a phenomenon in which the whole looks white due to the deodorant) and chalk mark (a phenomenon in which the friction part looks white due to friction) occur, which is not preferable in terms of appearance. .

On the other hand, in Patent Document 2, a non-halogen flame retardant that is sparingly soluble in water and a deodorant having a deodorant component supported on inert inorganic porous particles, together with a binder resin, A deodorant flame retardant fabric suitable as a vehicle interior material is disclosed in which at least one surface, for example, the back surface of a fabric is coated so that the dry coating amount is 20 to 200 g / m ² . Further, as the deodorizing component, amine compounds (hydrazine compounds are preferred), metal compounds (zinc silicate and zinc oxide are preferred) and the like are disclosed. However, in this case, since the coating amount, particularly the amount of the binder resin, is large, the deodorant is buried in the binder resin, and a sufficient deodorizing effect is not exhibited, or the fabric texture becomes coarse. was there.

  ADVANTAGE OF THE INVENTION According to this invention, the fabric for deodorant vehicle interior materials which has a deodorizing performance with respect to various malodor components, such as a living odor, a tobacco odor, and a pet odor, without impairing the original texture, touch, and appearance of a fabric. Can be provided.

  Hereinafter, embodiments of the present invention will be described in detail.

  In the present invention, the polyester fiber fabric means a fabric mainly composed of polyester fibers. As the polyester fiber fabric, as well as a polyester fiber alone, fibers other than polyester fiber (for example, synthetic fiber other than polyester fiber, semi-synthetic fiber, regenerated fiber, Natural fibers or the like) may be combined by a technique such as blending, blending, knotting, knit, knit or the like.

  Examples of the polyester fiber include polyethylene terephthalate, polybutylene terephthalate, and polytrimethylene terephthalate. However, the polyester fiber is not limited thereto, and examples of the third component include isophthalic acid sulfonate, adipic acid, and isophthalic acid. Fibers obtained by copolymerizing acid, polyethylene glycol, or the like, or fibers obtained by blending these copolymers or polyethylene glycol may be used. These fibers can be used singly or in combination of two or more. Of these, polyethylene terephthalate is preferred because of its excellent physical properties and availability at low cost.

  The form of the fabric is not particularly limited, and examples thereof include woven fabrics, knitted fabrics, and nonwoven fabrics. In the present invention, the back surface of the fabric refers to one surface that does not contact the vehicle interior space when used as a vehicle interior material.

  The fabric for a deodorant vehicle interior material according to the present invention has (A) a composite of silicon dioxide and zinc oxide as a deodorant component and (B) a polyhydrazide compound on the back surface of the polyester fiber fabric. (C) It is provided together with a binder resin. When the composition containing these components (A) to (C) is applied only to the back surface of the fabric, when used as a vehicle interior material, the front (front) surface, that is, the side in contact with the vehicle interior space (with the human body) Since one surface of the contact side) maintains the original tactile sensation and appearance of the fabric, it is excellent in usability. Even if whitening or chalk marks are generated, they are only generated on the back surface, so that there is no practical problem.

  The composite of (A) silicon dioxide and zinc oxide used in the present invention is not particularly limited, and examples thereof include an amorphous composite of silicon dioxide and zinc oxide. Such an amorphous composite is obtained, for example, by mixing an aqueous solution of sodium silicate with an aqueous solution of a water-soluble zinc compound such as zinc chloride or zinc sulfate, and reacting them to form an amorphous form of gel-like silicon dioxide and zinc oxide. It is obtained by preparing a composite slurry and drying it. By using zinc compounds, malodorous components such as ammonia, trimethylamine (above, life odor), acetic acid (life odor, tobacco odor, pet odor), hydrogen sulfide (life odor, tobacco odor), isovaleric acid (pet odor), etc. However, it is chemisorbed by coordinate bond with zinc and exhibits a deodorizing effect. In addition, by using zinc having deodorizing performance as an oxide and a composite with silicon dioxide, the deodorant component can be stabilized in an active state, and the deodorizing effect can be sustained. Furthermore, there is almost no re-release of the adsorbed malodorous component.

Here, the weight ratio of silicon dioxide to zinc oxide is preferably silicon dioxide: zinc oxide = 1: 10 to 10: 1, and more preferably 1: 5 to 5: 1. When the weight ratio is within this range, the effect of stabilizing the deodorant component is excellent. In terms of adsorptivity, the composite is preferably a porous body, particularly a porous body having a specific surface area of 50 m ² / g or more. Furthermore, from the viewpoint of the texture of the resulting fabric, the average particle size of the composite is preferably 10 μm or less.

Application amount of composite of zinc oxide and silicon dioxide to polyester fiber fabric (dry weight) is preferably 0.1 to 30 g / ^{m 2,} and more preferably from 1 to 20 g / ^{m 2.} There exists a possibility that sufficient deodorizing effect may not be acquired as the application amount is less than 0.1 g / m ² . If the applied amount exceeds 30 g / m ² , the texture of the fabric may become coarse. A more preferable upper limit of the adhesion amount is 15 g / m ² , an even more preferable upper limit is 10 g / m ² , and a particularly preferable upper limit is 5 g / m ² .

Next, (B) polyhydrazide compound which is another deodorant component will be described.
The polyhydrazide compound refers to a compound having two or more hydrazide groups (—NH—NH ₂ ) in one molecule. By using a polyhydrazide compound, malodorous components such as formaldehyde, propanal, butanal (tobacco odor), acetaldehyde, isovaleraldehyde (together, pet odor) are chemisorbed by a dehydration condensation reaction with the polyhydrazide compound. Deodorizing effect is demonstrated. Specifically, a dehydration condensation reaction occurs between the hydrazide group of the polyhydrazide compound and the aldehyde group of the aldehyde. As described above, zinc oxide (used as a composite with silicon dioxide) cannot be expected to have a deodorizing effect on odors containing aldehydes as malodorous components, but by using a polyhydrazide compound in combination, the above weak points are compensated. It can exert a wide range of effects on various malodorous components such as life odor, tobacco odor, pet odor and the like.

  Specific examples of the polyhydrazide compound include oxalic acid dihydrazide, malonic acid dihydrazide, succinic acid dihydrazide, glutamic acid dihydrazide, adipic acid dihydrazide, pimelic acid dihydrazide, suberic acid dihydrazide, azelaic acid dihydrazide, sebacic acid dihydrazide, Dihydrazide, terephthalic acid dihydrazide, isophthalic acid dihydrazide, tartaric acid dihydrazide, malic acid dihydrazide, iminodiacetic acid dihydrazide, itaconic acid dihydrazide, dodecanedihydrazide, hexadecanedihydrazide, naphthoedihydrazide, pyridinedihydrazide, dipyridinedihydrazide Dihydrazide compound having two hydrazide groups in one molecule), que Acid trihydrazide, trinitroacetic acid trihydrazide, nitriloacetic acid trihydrazide, cyclohexanetricarboxylic acid trihydrazide, ethylenediaminetetraacetic acid tetrahydrazide, naphthoic acid tetrahydrazide, polyacrylic acid hydrazide (having 3 or more hydrazide groups in one molecule) Polyhydrazide compounds). These can be used individually by 1 type or in combination of 2 or more types.

  Among the polyhydrazide compounds, the amount of hydrazide groups reacted per unit weight is large, and from the viewpoint of obtaining a high deodorizing effect, oxalic acid dihydrazide, malonic acid dihydrazide, succinic acid dihydrazide, glutamic acid dihydrazide, adipic acid It is preferably at least one selected from the group consisting of dihydrazide, citric acid trihydrazide, trinitroacetic acid trihydrazide, and naphthoic acid tetrahydrazide.

  The polyhydrazide compound may be coordinated with a metal to form a complex. By using a metal complex, a deodorizing effect can be exerted on a wide range of malodorous components. Examples of the metal forming the metal complex include alkali metals, alkaline earth metals, and rare earth metals, and may be appropriately selected according to the target malodorous component. Among these, from the viewpoint of deodorizing effect, it should be at least one selected from the group consisting of silver, copper, zinc, lead, iron, aluminum, indium, tin, titanium, manganese, nickel, cobalt, platinum, and palladium. Is preferred.

  The metal complex of the polyhydrazide compound can be produced by a known method such as a solution method. Specifically, for example, a complex of a desired metal and a polyhydrazide compound can be obtained by dissolving and stirring a desired metal chloride or the like and a polyhydrazide compound in a solvent.

  Furthermore, the polyhydrazide compound (including the metal complex, the same applies hereinafter) may be supported on the inorganic porous body. When the malodorous component is physically adsorbed on the inorganic porous body, a higher deodorizing effect can be obtained.

  Specific examples of the inorganic porous material include silica-based inorganic porous materials such as silica gel, silica aerosol, and colloidal silica; alumina-based inorganic porous materials such as activated alumina; aluminosilicate zeolite, metallosilicate zeolite, and aluminophosphate. Zeolite-based inorganic porous materials such as zeolite; silicate mineral-based inorganic porous materials such as kaolinite, montmorillonite, mica; mesoporous inorganic porous materials such as mesoporous silica; hydroxyapatite, layered zirconium phosphate, heteropolyacid salt And inorganic porous materials such as metal oxides and hydroxides including porous manganese oxide. These can be used alone or in combination of two or more. Among these, from the viewpoint of deodorizing effect and safety, a silicate mineral-based inorganic porous body is preferable, and a phyllosilicate mineral-based inorganic porous body is more preferable.

  More specific examples of the phyllosilicate mineral-based inorganic porous material include clay minerals such as kaolinite, smectite, montmorillonite, sericite, illite, glowconite, chlorite, talc and zeolite; muscovite, phlogopite , Mica such as biotite, phlogopite mica, fluorotetrasilicon mica, sericite, soda mica, vanadine mica, iron mica, chinwald mica, chrome mica, pearl mica, lithia mica, and red mica.

  Examples of the method for supporting the polyhydrazide compound on the inorganic porous material include known methods such as a solution impregnation method. The amount of the polyhydrazide compound supported on the inorganic porous body is preferably 0.1 to 50% by weight, more preferably 0.5 to 20% by weight with respect to the inorganic porous body.

The amount (dry weight) of the polyhydrazide compound applied to the polyester fiber fabric is, alone or in the case of a metal complex, as a total amount with the metal, and when it is supported on the inorganic porous material, the inorganic porous material. the total amount of the body is preferably 1 to 30 g / ^{m 2,} more preferably 3 to 15 g / ^{m 2.} If the applied amount is less than 1 g / m ² , a sufficient deodorizing effect may not be obtained. If the application amount exceeds 30 g / m ² , the texture may become coarse.

In the present invention, the deodorant components (A) and (B) are applied to the back surface of the polyester fiber fabric together with (C) the binder resin.
The binder resin is not particularly limited, and a normal binder resin for fiber processing can be used. Specifically, for example, urethane resin, acrylic resin, silicone resin, and the like. Of these, urethane resin is preferred because it has little influence on the texture of the fabric and is excellent in durability.

Application amount of the binder resin to the polyester fiber fabric (dry weight), it is required a 0.3~7g / ^{m 2,} it is preferable that 0.6~2g / ^{m 2.} By setting the amount of the binder resin to be within the above range and applying the deodorant components (A) and (B) to the back surface of the fabric through this, without impairing the fabric's original texture, feel and appearance, Deodorant performance can be provided. Further, the deodorant components (A) and (B) can be prevented from being buried in the binder resin, and a sufficient deodorizing effect, in particular, a deodorizing effect excellent in immediate effect can be exhibited. In general, a synthetic resin used as a binder resin has a property that when heated, organic substances are decomposed and easily burned. Therefore, in the fabric provided with this, the combustibility tends to be remarkably increased. However, by setting the application amount of the binder resin within the above range, the increase in combustibility can be minimized. That is, it has excellent combustion resistance. If the applied amount is less than 0.3 g / m ² , the deodorant component cannot be sufficiently fixed and the deodorant component may fall off. If the applied amount exceeds 7 g / m ² , the texture of the fabric may become coarse or the flammability may increase significantly.

  At this time, (A) Application of binder resin to the total amount of application amount (dry weight) of composite of silicon dioxide and zinc oxide and (B) application amount (dry weight) of polyhydrazide compound The ratio of the amount (dry weight) (that is, dry weight of component (C) / {dry weight of component (A) + dry weight of component (B)) × 100 (%)) is 0.4 to 80% by weight. However, it is preferably 0.4 to 35% by weight. A more preferred lower limit is 0.75% by weight or more, a still more preferred lower limit is 1.5% by weight or more, and a particularly preferred lower limit is 3% by weight or more. A more preferred upper limit is 20% by weight or less. In this way, by setting the proportion of the binder resin to be small, the deodorant components (A) and (B) are held in the polyester fiber fabric via the binder resin without being embedded in the binder resin. Will be. Therefore, the immediate effect of the deodorizing effect can be further enhanced. When this ratio is less than 0.4% by weight, the deodorant component easily falls off when used on a part where a person repeatedly gets on and off, such as a vehicle interior material, particularly a seat sheet material, and has a deodorizing effect. There is a possibility that the durability of the resin becomes insufficient. If this ratio exceeds 35% by weight, the deodorant component may be buried in the binder resin, and a sufficient deodorizing effect may not be exhibited.

  The fabric for deodorant vehicle interior materials of the present invention is obtained by dispersing (A) a composite of silicon dioxide and zinc oxide, (B) a polyhydrazide compound, and (C) a binder resin described above in water. It can be produced by applying the treatment liquid to the back surface of the polyester fiber fabric, and then drying and curing.

  The method for applying the treatment liquid to the back surface of the fabric is not particularly limited, and examples thereof include a spray method, a gravure method, and a coating method. Of these, the gravure method is preferred from the viewpoint of the texture of the resulting fabric. In addition, you may add other functional components, such as a flame retardant and a softener, to a process liquid within the range which does not impair the effect of this invention.

Hydrogen sulfide was generated by injecting 75 μl of (0.64 mol / l) and left in an atmosphere of 20 ° C. × 65% Rh for 30 minutes.
Next, 3.5 liters of hydrogen sulfide generated in the above and air were injected into another odor bag so that the hydrogen sulfide concentration in the bag was 20 ppm.
Further, in another odor bag, a test piece cut to a length of 10 cm and a width of 14.5 cm was put, and after 3 liters of air containing 20 ppm of hydrogen sulfide was injected, the atmosphere was 20 ° C. × 65% Rh. I left it alone.
After 15 minutes and 120 minutes from the injection of air containing hydrogen sulfide, the residual hydrogen sulfide concentration in the odor bag containing the test piece was measured using a detector tube (Gastech 4LK, manufactured by Gastec Co., Ltd.). . The measured value obtained at this time was A (ppm).
Further, as a blank, the same operation was performed without inserting a test piece, and the residual hydrogen sulfide concentration was measured. The measured value obtained at this time was defined as B (ppm). The deodorization rate (%) was calculated by the above formula.

○: Deodorant is not removed.
Δ: Slight detachment of deodorant is observed.
X: Omission of deodorant is clearly observed.

(4) Combustion resistance It evaluated based on the test method of US automobile safety standard FMVSS302. The test piece cut to 350 mm in length x 100 mm in width is indirectly flamed with a gas burner for 15 seconds and ignited, and the fire is extinguished after the ignited flame crosses the marked line 38 mm from the end. The distance and time to do was measured. Ten points were measured in each of the vertical and horizontal directions, the combustion rate was calculated, and the determination was made according to the following criteria.
○: The test piece did not ignite, or the ignited flame was extinguished before the marked line, and has excellent combustion resistance.
(Triangle | delta): The maximum value of a combustion rate is 80 mm / min or less, and it is a little inferior to combustion resistance.
X: The maximum value of the burning rate exceeds 80 mm / min and is inferior in combustion resistance.

Table 2 shows the results of evaluating the deodorant fabrics of Examples and Comparative Examples.
Each of the deodorant fabrics of Examples 1 and 2 exhibited an excellent deodorizing effect against various malodorous components. Particularly effective against ammonia and hydrogen sulfide. Further, the deodorant did not fall off, and furthermore, the original texture and appearance of the fabric were maintained, and the combustibility was at a level with no problem.
On the other hand, in the deodorant fabric of Comparative Example 1, the deodorant was removed. In the deodorant fabrics of Comparative Examples 2 and 3, a sufficient deodorizing effect could not be obtained, and the texture was hard. Further, in the deodorant fabric of Comparative Example 2, a slight increase in combustibility was observed, and in the deodorant fabric of Comparative Example 3, a significant increase in combustibility was observed, which was inferior in combustion resistance.
In addition, the external appearance and tactile sensation of the front (front) surface of the deodorant fabric were at a level with no problem in both Examples and Comparative Examples.
