DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a finishing agent used for textiles such as clothing.

2. Description of the Related Art Conventionally, various textile finishing agents containing a quaternary ammonium salt as a main component have been used for the purpose of imparting flexibility to a textile product after washing. As the quaternary ammonium salt, a di-long chain type quaternary ammonium salt is generally used. However, the finishing agent for textile products containing a di-long chain type quaternary ammonium salt as a main component can provide a good flexibility-imparting effect to cotton products, but can be used for polyester or silk used in fashionable clothing. Has little softening effect on textiles,
The effect of imparting flexibility and smoothness is also small. Also,
Attempts have been made to use a silicone compound in combination with a quaternary ammonium salt for the purpose of improving various properties of a textile product finish. For example, Japanese Patent Laid-Open No. 1-1
No. 62878 discloses a water-dispersible cationic softener,
A conditioning formulation for aqueous based textiles comprising a non-ionic softener comprising certain siloxanes is disclosed. Japanese Patent Application Laid-Open No. 2-191774 discloses a concentrated softening agent for clothing containing a quaternary ammonium salt and a specific silicone derivative. However, at present, there is no finish for textile products that can impart excellent flexibility, flexibility and smoothness to textile products such as polyester and silk.

[0003]

Therefore, the present invention provides excellent flexibility, flexibility and smoothness for various textiles and clothing such as fashionable clothing made of synthetic fibers such as polyester and silk. It is an object of the present invention to provide an aqueous finish composition for textiles, which is capable of imparting water.
