Description

  The present invention relates to a fiber treatment composition. In detail, this invention relates to the fiber treatment agent composition which can exhibit a lasting deodorizing effect.

In recent years, there is an increasing tendency to worry about bad odors attached to fibers such as body odor such as sweat odor, food odor such as yakiniku odor, and tobacco odor.
"Deodorization technology" has been developed in industrial filters and the like, but in recent years, home-use deodorant sprays have been released by various companies, and the market is expanding year by year (Patent Documents 1 to 3). Among them, a liquid deodorant composition for textiles, which is a combination of zinc sulfate and methylglycine diacetic acid at a specific molar ratio, is excellent in the effect of deodorizing a composite odor adhering to the textiles (Patent Literature) 1). The liquid deodorant composition of patent document 1 is utilized as a commercial item in the form which used the quaternary ammonium compound as an antibacterial agent together.
Moreover, the softening agent composition which mix | blended the antibacterial agent is also known (patent document 4).

Although this invention is not restrict | limited by a specific theory, it is thought that the mechanism by which a continuous deodorizing effect is acquired by combined use with (A) component and (B) component is as follows.
Since the component (B) is an antibacterial agent, it is expected to exhibit a deodorizing effect alone, but the deodorizing effect was equivalent to the deodorizing effect of the component (A) alone (comparison described later). Examples 5-6).
The component (A) not only exhibits a deodorizing effect due to its antibacterial properties, but also has high permeability to textile products. Therefore, when (A) component is mix | blended with a fiber processing agent, the permeability to the textiles of another deodorant component ((B) component) can be improved.
Therefore, when the component (A) and the component (B) are used in combination, the component (B) penetrates deep into the fiber product and can act on malodorous components that penetrate deep into the fiber product (in addition, The malodorous component penetrating deep into the textile product is considered to be the cause of the problem of conventional deodorizers (a phenomenon in which malodor is felt again over time after spraying)).
Due to the deodorizing effect of the component (B) and the deodorizing effect of the component (A) itself that are exhibited in the back of the textile product, the fiber treatment agent composition of the present invention is the component (A) or the component (B) alone. It is thought that the lasting deodorizing effect which cannot be obtained by use can be exhibited (contrast with Examples 7-8 described later and Comparative Examples 5-6).
