Description

  The present invention relates to a deodorant suitable for fiber processing and a fiber product processed using the deodorant. In particular, a deodorant with an excellent deodorizing effect against bad odors such as sweat odor (ammonia, acetic acid, isovaleric acid = according to the provisions of the Textile Technology Association and the deodorization mark), and processing using this deodorant This is related to textile products.

  Deodorants applied to bad odors, especially sweat odors, need to deodorize the opposite odors of ammonia, acetic acid and isovaleric acid. For example, Patent Document 1 (Japanese Patent Laid-Open No. 4-109954) proposes an adsorbent using a composite of aluminum tripolyphosphate and zinc oxide + zinc hydroxide. Further, for example, Japanese Patent Application Laid-Open No. 2006-20717 proposes a deodorant containing a photocatalyst and a layered silicate mineral.

Japanese Patent Laid-Open No. 4-109954 JP 2006-20717 A

  However, the deodorizers proposed in Patent Documents 1 and 2 are insufficient in performance to deodorize both ammonia, acetic acid and isovaleric acid, which are sweat odor components. In particular, the deodorizer proposed in Japanese Patent Application Laid-Open No. 2006-20717 uses a photocatalyst. For this reason, light irradiation is necessary. Thus, conventional deodorants do not give an effective deodorizing effect over a wide range of acids and bases such as ammonia, acetic acid, and isovaleric acid. For this reason, it has been difficult to obtain a deodorant having a deodorizing performance that is well balanced against a wide range of types of bad odors, particularly sweat collection, in a single solution.

  The present invention has been made in view of the above, and a deodorant having a deodorizing effect in a well-balanced manner against bad odors (sweat odor) containing ammonia, acetic acid, isovaleric acid, and the like in a single solution, and the odor eliminating agent. An object of the present invention is to provide a textile product deodorized using an odorant.

In order to solve the above-mentioned problems and achieve the object, according to the present invention,
Component (a) aluminum tripolyphosphate;
Component (b) zinc oxide;
Component (c) smectite;
A deodorant comprising component (d) water is provided.

  Moreover, according to the preferable aspect of this invention, it is desirable to further contain a component (e) resin binder.

  Moreover, according to this invention, the fiber product formed by making the fiber contain the above-mentioned deodorant and drying is provided.

  According to the present invention, a deodorant having a deodorizing effect in a well-balanced manner against sweat odors including various bad odors such as ammonia, acetic acid, and isovaleric acid, and a deodorizing process using this deodorant. The effect that the textile product which can be provided can be provided.

As described above, the deodorant according to the present invention comprises component (a) aluminum tripolyphosphate,
Component (b) zinc oxide;
Component (c) smectite;
A deodorant containing component (d) water.

  Component (a) aluminum tripolyphosphate (aluminum tripolyphosphate) is effective against basic malodors such as ammonia.

  The component (b) zinc oxide is effective against acidic malodors such as acetic acid and isovaleric acid. Zinc oxide is also a photocatalyst. For example, the organic substance can be oxidatively decomposed by a strong oxidizing power excited by light such as ultraviolet rays and visible light. This action exhibits a more excellent deodorizing function. Further, the zinc oxide may be subjected to visible light photocatalytic treatment by impurity doping or the like. By adding a photocatalyst and irradiating light from a fluorescent lamp, the bad odor can be removed in a more balanced manner.

  Component (c) smectite is a layered silicate mineral. Smectite has thixotropy and can also prevent the deodorant component from settling.

  In general, when dealing with individual malodors, it is common to use basic deodorant components for acidic malodors and acidic deodorant components for basic malodors. Here, in order to deodorize these complex odors at once, when an acidic deodorant and a basic deodorant are mixed, a reaction occurs, and the deodorization performance is compared to the case of using it alone. Is extremely reduced.

  On the other hand, the combination of three components of aluminum tripolyphosphate, zinc oxide and smectite in the present invention exhibits high deodorizing performance against each acid and basic malodor, and can be deodorized with a good balance in one liquid. .

(Creating a sample for evaluating the deodorization rate of malodorous gases)
Next, in order to evaluate the deodorization rate of malodorous gas, a sample was prepared according to the following procedure. Deodorants sa1 to sa3 (Examples) and deodorizers sb1 to sb7 (Comparative Examples) having the composition shown in Table 1 below are applied to filter paper obtained by cutting the deodorant adjusted to 10 cm × 10 cm in size by the above-described method. Drop with a dropper. Then, the dropped sample is put in an oven at 120 ° C. and dried for 30 minutes. Further, after drying at 105 ° C. for 2 hours, humidity is adjusted at 20 ° C. and 65 RH for 24 hours or more. Thereby, a sample is prepared.

(Deodorization rate evaluation method for malodorous gases)
Moreover, the measuring method of the deodorization rate of malodorous gas is demonstrated.
Next, one sample is put into a 3 liter Tedlar (registered trademark) bag, and the air in the bag is vacuum degassed. Next, 3 liters of air having a predetermined malodor concentration is injected, and the malodor concentration after 120 minutes is measured with a detector tube. The initial malodor concentration is 100 ppm ammonia, 100 ppm acetic acid, and 50 ppm isovaleric acid. The rate of decrease relative to the initial concentration was defined as the deodorization rate. The larger the deodorization rate, the greater the deodorization effect (unit%).

  As is clear from Table 1, it can be seen that the deodorizers sa1 to sa3 according to Examples 1 to 3 exhibit deodorizing performance in a well-balanced manner in ammonia, acetic acid, and isovaleric acid. On the other hand, in the deodorizers sb1 to sb7 according to the comparative examples, an effect appears only for any one or two offensive odors among ammonia, acetic acid, and isovaleric acid. Thus, the composition of the present invention shows a deodorizing performance in a well-balanced manner for various deodorants.

  As described above, the deodorant according to the present invention is useful in the case of exerting a deodorizing function against various types of bad odors, particularly sweat odor, with a single solution.
