Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a softener composition, and more particularly to a synthetic fiber which imparts excellent flexibility and elasticity (fluffiness) to synthetic fibers, and has no dyeing property on fibers. The present invention relates to a liquid softener composition that does not change color tone during high-temperature storage.

[0002]

2. Description of the Related Art At present, most of products commercially available as household softeners are mainly composed of a quaternary ammonium salt having 1-2 long-chain alkyl groups in one molecule. This is because the quaternary ammonium salt exhibits a good softening effect on various fibers in a small amount. However, the quaternary ammonium salt exerts an effect of imparting excellent flexibility to cotton, but is not sufficiently effective to synthetic fibers such as acrylic, polyester and polyamide. .

[0003] Recently, a flexible component having excellent biodegradability and containing an ester group in a molecule has been developed from the viewpoint of environmental problems. This soft component adjusts the pH of the softener to an acidic side in order to suppress hydrolysis of the ester group. However, a dye is added to the softener to color the product itself. By lowering the pH, the dye fades or discolors particularly during storage at a high temperature to change the color tone of the softener. I have.

Further, in the currently most widely used fully automatic washing machine, a detergent and a softening agent are previously charged into a dedicated inlet, and after the washing program is started, an appropriate timing of the washing machine is set by an automatic charging system of the washing machine. Is put into the washing tub. However, when the softening agent is introduced into the inlet of the washing machine, the softening agent may accidentally adhere to clothing in the washing tub. In such a case, a problem arises in that the dye contained in the softening agent adheres to the clothes and remains on the clothes even after the washing is completed. Furthermore, since the viscosity of the softening agent itself is also reduced in order to make it easier to input the softening agent, the penetration of the softening agent into clothing is increased, which further exacerbates the above problem. The dye in such a softening agent has a property of dyeing more strongly on garments mainly containing synthetic fibers among garments. Therefore, unlike clothing that is relatively hard to see by others, such as towels and underwear mainly made of cotton fiber, dyes are dyed in clothing mainly composed of synthetic fibers that are often used for fashionable clothing. The problem is very serious.

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems and has an excellent flexibility-imparting effect on synthetic fibers. It is an object of the invention to provide a liquid softener composition that is not water-soluble.
