  The deodorizers of Examples 1 to 7 are excellent in settling inhibitory properties, and the deodorant processing liquid obtained using the deodorant is excellent in low foaming property and settling suppressive properties, impregnated with the deodorant processing solution and dried. The deodorant processed fabric (textile product) obtained in this way has high ammonia deodorization rate and acetic acid deodorization rate before washing and after washing and drying, respectively, and excellent water absorption before washing and after washing and drying In addition, it was excellent in texture before washing and after washing and drying.

About the deodorant of the comparative example 1 which does not contain a binder polymer, the deodorizing processing liquid, and the deodorizing processed fabric (textile product) obtained by impregnating and drying the deodorizing processing liquid, washing -The ammonia deodorization rate after drying was low.
About too much content of the binder polymer, the deodorant of Comparative Example 2, the deodorant processing liquid, and the deodorant processed fabric (textile product) obtained by impregnating and drying the deodorant processing liquid, The deodorizing liquid was poor in low foaming property and the acetic acid deodorizing rate after washing and drying was low.
About the deodorant of the comparative example 3 which does not contain a dispersing agent, a deodorizing processing liquid, and the deodorizing processed fabric (textile product) obtained by impregnating and drying the said deodorizing processing liquid, deodorizing The anti-settling property of the agent was poor, the anti-settling property of the deodorant processing solution was poor, the ammonia deodorization rate, particularly the ammonia deodorization rate after washing and drying was low, and the water absorption was poor.
For the deodorant, the deodorant processing liquid of Comparative Example 4 and the deodorant processed fabric (textile product) obtained by impregnating and drying the deodorant processing liquid, the content of the dispersant is too small. -The ammonia deodorization rate after drying was low and the water absorption was slightly inferior.

  As described above, the deodorizers of Examples 1 to 7 are excellent in settling inhibitory properties, and the deodorant processing liquid obtained using the deodorizer is excellent in low foaming property and settling inhibitory properties, and the deodorant finishes. The deodorant processed fabric (textile product) obtained by impregnating and drying the liquid has high ammonia deodorization rate and acetic acid deodorization rate before washing and after washing and drying, respectively, before washing and after washing and drying It was excellent in water absorption and excellent in texture before washing and after washing and drying. In addition, ammonia, acetic acid, and isovaleric acid can be cited as causes of bad odor due to sweat. From the above results, the deodorant according to the present invention is an acid (acetic acid) that causes bad odor due to sweat and Since it was shown that the deodorization rate of ammonia was high, it was shown that the deodorizing property with respect to sweat odor was high. In addition, isovaleric acid is the same acid as acetic acid, and it is thought that deodorizing property is similar to acetic acid.

  The deodorizing system of the present invention is useful for deodorizing bad odors containing acid / base components, particularly sweat odors.
