DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber which reduces stains adhering to fibers or textiles, and which gives fibers the effect of easily removing dirt attached to fibers or textiles by ordinary washing. The present invention relates to a treatment composition.

[0002]

2. Description of the Related Art In general, it is technically impossible to completely remove dirt adhering to textiles such as fibers and clothing by using a generally available type of detergent composition or clothing detergent. It is known to be difficult.

[0003] Therefore, an attempt has been made to improve the removability of dirt when a general cleaning composition is used by treating the surface of a fiber or a textile product with a specific treating agent.
No. 46358 and JP-A-5-163679.

However, most of the treating agents described in these publications are intended to solve the problem by controlling the fiber surface to be hydrophilic or hydrophobic, and therefore, the treatment agents are hydrophilic. In addition, the stains that can be removed in a practical system are limited because of the presence of hydrophobic stains.

[0005]

Under such circumstances, the inventors of the present invention have conducted intensive studies, and as a result, a polycyclic aromatic sulfonic acid having a condensed ring, an organic solvent and water were blended. By applying the fiber treating agent composition to the fiber, the effect of removing hydrophilic or hydrophobic stains attached to the fiber or textile product is improved even in washing with a normal detergent, and furthermore, such a fiber treating agent composition The present inventors have found that the effect of removing stains can be maintained for a long period of time even when fibers or fiber products treated with an object are repeatedly washed, and have completed the present invention.

That is, the present invention provides an organic solvent having a condensed ring.
The present invention provides a fiber treatment composition characterized by containing a polycyclic aromatic sulfonic acid and water.

In the present invention, as the organic solvent, a compound represented by the following formula (1), an N-alkylpyrrolidone represented by the following formula (2) or an alkylene carbonate having 1 to 4 carbon atoms is preferably used. preferable.
