Description

  The present invention relates to a method for producing a deodorant fabric that exhibits excellent deodorizing properties against acetic acid and acetaldehyde, which are the main components of tobacco odor, and a deodorant fabric obtained by the production method, and The present invention relates to a textile product using an odorous fabric.

  Conventionally, many proposals have been made on techniques for imparting deodorizing properties to textile materials and daily necessities. For example, a method of adhering a metal hydroxide such as magnesium hydroxide, calcium hydroxide, and zirconium hydroxide to a honeycomb-like substance and adsorbing a lower fatty acid present in the gas (see, for example, Patent Document 1), adsorbing aldehydes Aldehyde deodorant coating agent (for example, refer to Patent Document 2) that uses a nitrogen-containing compound having an ability and zeolite together, porous materials such as metal oxides and metal hydroxides, inorganic acid salts, organic acid salts, And the method (for example, refer patent document 3 and patent document 4) etc. which obtain a deodorizing fiber material, such as an acetic acid and an aldehyde, using a polyamine compound and a hydrazide compound via a synthetic urethane resin binder, etc. are proposed.

  However, deodorization of aldehyde is expressed by reacting the amino group of the amine compound with the aldehyde (Schiff reaction) to form a Schiff salt, but this reaction is difficult to proceed as the basicity increases, and is intended for deodorization of acetic acid. It was difficult to use together with the basic compound. In particular, when a metal hydroxide effective for acetic acid deodorization is used in combination with an amine compound, due to the basicity of the metal hydroxide, the Schiff reaction between the amino group and the aldehyde group of the amine compound is inhibited and the aldehyde deodorization effect is drastically reduced. There was a problem.

  As described above, the proposals up to now have the ability to deodorize both acetic acid and acetaldehyde at the same time, although odor deodorizing ability to either acetic acid or aldehydes, which are the main components of tobacco odor, is recognized. Alternatively, there has been a problem that once the deodorized odor is released again.

  In the present invention, the type of fabric is not particularly limited as long as it is a fabric containing organic fibers. The form is a woven fabric, a knitted fabric, a non-woven fabric, or the like, and the thickness, basis weight, appearance, etc. of the fabric are not limited. As the types of fibers constituting the fabric, synthetic fibers such as polyester and nylon, regenerated fibers such as rayon, natural fibers such as cotton, wool, and silk, and composites thereof can be used. Polyester fibers are particularly preferable. The polyester fiber is produced from a dicarboxylic acid component and a diglycol component. As the dicarboxylic acid component, terephthalic acid is preferably used mainly, and as the diglycol component, it is preferable to use one or more alkylene glycols selected from ethylene glycol, trimethylene glycol and tetramethylene glycol. Moreover, the polyester resin may contain a third component in addition to the dicarboxylic acid component and the glycol component. Examples of the third component include cationic dye dyeable anion components such as sodium sulfoisophthalic acid; dicarboxylic acids other than terephthalic acid such as isophthalic acid, naphthalenedicarboxylic acid, adipic acid, sebacic acid; and glycol compounds other than alkylene glycol. For example, one or more of diethylene glycol, polyethylene glycol, bisphenol A, and bisphenol sulfone can be used. Furthermore, aliphatic polyester fibers such as polylactic acid fibers and stereocomplex polylactic acid fibers may be used.

  In the resin forming the organic fiber, a matting agent (titanium dioxide), a fine pore forming agent (organic sulfonic acid metal salt), a coloring inhibitor, a heat stabilizer, a flame retardant (antimony trioxide), if necessary. ), Optical brightener, color pigment, antistatic agent (sulfonic acid metal salt), hygroscopic agent (polyoxyalkylene glycol), antibacterial agent, and other inorganic particles may be contained.

  The shape of the organic fiber may be a short fiber or a long fiber (multifilament). Furthermore, a false twisted crimped yarn subjected to a normal false twist crimping process or a composite yarn obtained by subjecting two or more kinds of constituent yarns to air-mixing or composite false twisting may be used.

  The single yarn fiber fineness, total fineness, and number of single yarns of the organic fiber are preferably in the range of single yarn fiber fineness of 0.00001 to 10.0 dtex, total fineness of 20 to 300 dtex, and single yarn number of 10 to 200. Further, the cross-sectional shape of the single yarn fiber is not limited, and may be an irregular cross-sectional shape such as a triangular shape, a flat shape, a constricted flat shape, a cross shape, a hexagonal shape, or a hollow shape in addition to a normal circular cross section. In particular, the use of a constricted flat cross-sectional shape is preferable because water absorption is improved.

  The fabric may be a woven or knitted fabric knitted and woven by a normal method, and the woven or knitted structure is not particularly limited. For example, woven structures such as plain weave, twill weave, and satin, and knitted structures such as tengu, smooth, milling, kanoko, denby, and tricot are preferably exemplified, but not limited thereto. The number of layers is preferably a single layer, but may be two or more. Especially, since the fabric comprised by a napping part and / or a pattern part and a ground organization part can be used as a car seat ground etc., it is preferable.

In the present invention, a deodorant A containing a metal hydroxide and an amine compound is attached to the fabric via a synthetic resin binder B having an acid value of 5 to 600 mgKOH / solid content g.
Here, the metal hydroxide is preferably a metal hydroxide having a water solubility of less than 1%. For example, calcium hydroxide, magnesium hydroxide, aluminum hydroxide, etc. hydroxide di Le Koniumu are exemplified. Of these, calcium hydroxide or magnesium hydroxide is particularly preferable in obtaining an excellent deodorizing effect on acetic acid.

  On the other hand, the amine compound having at least one primary amino group and having a boiling point or decomposition temperature higher than 160 ° C. is heat-set after obtaining an acetaldehyde deodorant and deodorant fabric. It is preferable that it is difficult to be decomposed.

  Such an amine compound is preferably an amine compound represented by the following chemical formula (Chemical Formula-1), Chemical Formula (Chemical Formula-2), Chemical Formula (Chemical Formula-3), or Chemical Formula (Chemical Formula-4).

ただし、上記化学式中のＲは −（ＣＸ_２）ｎ−、−（ＣＸ_２Ｏ）ｎ−、−（ＣＸ_２−ＣＸ_２Ｏ）ｎ−、−Ｃ６Ｈ４− ，−（ＣＸ_２）ｎ−Ｃ_６Ｈ_４−（ＣＸ_２）ｎ−であり、Ｘは−Ｈ、−ＣＨ_３、−ＣＨ_２ＣＨ_３、−ＣＨ_２ＣＨ_２ＣＨ_３であり、ｎ は１〜５である。

However, the R in the above formula _{- (CX 2) n -,} - (CX 2 O) n -, - (CX 2 -CX 2 O) n -, - C6H4-, - (CX 2) n-C 6 H ₄ - _(CX 2) is n-, X is _{-H, -CH 3, -CH 2 CH} 3, a -CH 2 _CH 2 _{CH 3,} n is 1-5.

  Especially, aromatic amines, such as polyalkylene polyamines, such as a triethylenetetramine and tetraethylenepentamine, polyethyleneimines, polyvinylamines, phenylenediamine, xylenediamine, are illustrated. In particular, polyethyleneimines and polyvinylamines are preferable for obtaining an excellent deodorizing effect on acetaldehyde.

Furthermore, in order to enhance the acetaldehyde deodorizing effect of the amine compound, it is also preferable that the amine compound is previously adsorbed (complexed) on a porous material. In this case, the porous material is preferably an oxide of a metal component selected from the group consisting of silicon, zinc, magnesium, and titanium, or activated carbon. In particular, a silicon oxide or a zinc oxide is preferred for enhancing the acetaldehyde deodorizing effect.

  Further, it is important that the synthetic resin binder B has an acid value in the range of 5 to 600 mgKOH / solid content g (preferably 30 to 400 mgKOH / g). By using the synthetic resin binder B, the synthetic resin binder B and the metal hydroxide form a metal hydroxide salt. However, when the acetic acid stronger than the binder acid group is encountered, the metal hydroxide migrates. As a result, it exhibits excellent acetic acid deodorization properties. As the acid value of the synthetic resin binder B, the acid value before the neutralization treatment is used when the synthetic resin binder B is neutralized.

  Here, when the acid value of the synthetic resin binder B is smaller than 5 mg KOH / solid content g, alkali due to the metal hydroxide becomes strong, and the acetaldehyde deodorizing effect of the amine compound may be impaired, which is not preferable. On the contrary, if the acid value of the synthetic resin binder B is larger than 600 mgKOH / g of solid content, the water resistance of the synthetic resin binder is undesirably lowered. In order to improve the miscibility of the synthetic resin binder B with the metal hydroxide or amine compound, it is preferable to adjust the pH of the synthetic resin binder B with ammonia or the like.

  The acid value of the synthetic resin binder B is a synthetic resin binder B in which the neutralized alkali is diffused by drying, and the 100 to 150 ° C. dry thin film solid content of the binder is neutralized with a non-airborne alkali. In the resin binder B, an acid such as hydrochloric acid is added to the binder, and the resulting solidified product is washed with water to obtain dry solids. These solids are dissolved in alcohol and acetone, and determined by KOH titration. Good.

  When the binder is neutralized with ammonia or the like, the binder is usually neutralized in a wet state (emulsion, water dispersion, etc.) when used. In this state, the acid value is temporarily increased by the amount neutralized. Becomes lower. However, since ammonia and air-diffusing amine are diffused by drying during processing, the binder on the processed material actually returns to the acid value before neutralization.

  Examples of the synthetic resin binder B include acrylic resin, urethane resin, vinyl acetate resin, ethylene vinyl acetate resin, ester resin, and silicon resin. Of these, acrylic resins and urethane resins are preferable. Examples of the acrylic resin binder having an acid value as described above include DIC Corporation Boncoat VE and DIC Corporation Boncoat HV-E. Examples of the urethane resin binder having an acid value include DIC Corporation. ) Hydran HW-311 manufactured by DIC, AP-40 manufactured by DIC Corporation, Superflex 300 manufactured by Daiichi Kogyo Seiyaku Co., Ltd. and the like. Further, in order to adjust the flexibility of the deodorant fabric of the present invention, in addition to the synthetic resin binder B, a synthetic resin binder having no acid group (for example, Bondic 2210 manufactured by DIC Corporation, Bondic manufactured by DIC Corporation). 2220, DIC Corporation Bondic HW-930) is also preferably used in combination.

The solid content ratio of the metal hydroxide, the amine compound, and the synthetic resin binder B is preferably in the range of 10:10 to 30:10 to 60 (more preferably 10:15 to 25:20 to 40).
The adhesion amount of the mixture of the metal hydroxide, the amine compound and the synthetic resin binder B to the fabric is preferably in the range of 5 to 30 g / m ² (10 to ²⁰ g / m ² ) in terms of solid content.

  The method for applying the mixture of the metal hydroxide, the amine compound, and the synthetic resin binder B to the fabric is not particularly limited, but thickeners such as polyethylene glycol, carboxymethyl cellulose, hydroxyethyl cellulose, and the like, with a predetermined concentration and a predetermined viscosity. A method of preparing an aqueous dispersion of the composition and coating the surface of the fabric with a gravure roll coater, a floating knife coater, rotary printing, spraying or the like is preferable. At that time, it is preferable that the coated product (the mixture) is not exposed on the non-coated surface, for example, a napped fabric is employed as the fabric, and the coated product (the mixture) is applied only to the surface of the ground tissue part, Preventing the coated product (the mixture) from being exposed on the surface of the napped portion side provides a deodorant with excellent durability without impairing the appearance, and is suitably used as a car seat or carpet. This is preferable.

The fabric on which the coated product (the mixture) is coated is preferably dried in a chamber at a temperature of 100 to 140 ° C. and further heat-treated at a temperature of 150 to 180 ° C.
Here, before, at the same time as or after applying the mixture to the fabric, dyeing, further brushing, conventional ultraviolet ray shielding or antibacterial agent, flame retardant, insect repellent, phosphorescent agent, retroreflective agent, negative ion Various processings that impart functions such as a generator, a water repellent, and an antiallergen may be additionally applied. Especially, when the flame retardant C is added to the said mixture as another agent, a flame retardance is added to the fabric finally obtained, and it is used suitably as a car seat ground, a carpet, etc., and is preferable. At that time, the flame retardant C is preferably at least one selected from the group consisting of phosphorus compounds, halogen compounds, antimony trioxide, aluminum magnesium hydroxide, and borates. . Specifically, phosphoric esters, phosphates, phosphate amides, phosphine oxide compounds, phosphorus compounds such as guanidine phosphate, halogen compounds such as hexabromododecane, decabromodiphenyl ether, antimony trioxide, metal Suitable examples include metal compounds such as hydroxides.

Moreover, as an antiallergen agent, aromatic hydroxy compounds, such as plant extracts, such as tannic acid and catechinic acid, hydroxybenzoic acid, and polyvinylphenol, etc. are preferable.
In the deodorant fabric thus obtained, the metal hydroxide and the weak acid group of the resin binder form a metal hydroxide salt, whereby the basicity of the metal hydroxide is weakened. At the same time, the metal hydroxide salt is stronger than the resin binder acid group, that is, the acetic acid of the metal hydroxide is transferred to acetic acid in an acetic acid atmosphere. A salt is formed, and acetic acid deodorizing property is also obtained. Thus, such a fabric has excellent deodorizing properties with respect to acetic acid and aldehydes. Furthermore, the deodorized odor is not easily released again.
