Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid soft finish composition for clothing which can impart excellent flexibility and antistatic properties to various fibers.

[0002]

2. Description of the Related Art Clothes have an unfavorable feeling because the fiber treatment agent is washed off or hardened due to deterioration of the fibers themselves during repeated wearing and washing. Occurs. Therefore, in recent years
In many households, a soft finish that can impart flexibility and antistatic properties to fibers is used. Current,
Most commercially available household softening agents are cationic surfactants having 1 to 2 long-chain alkyl groups and quaternary ammonium groups in one molecule (hereinafter, quaternary ammonium). It is referred to as a salt), and particularly has a di (hardened tallow alkyl) dimethylammonium salt as a main component.

The softening effect of these softening agents is brought about by lowering the friction coefficient of the fiber surface due to the lubricating effect of the lipophilic sites in the base molecule adsorbed on the fiber surface, but it has an excellent softening effect. The soft base is inevitably sticky to the treated clothing, so-called Greasy
y) It gives a feeling. The degree of this greedy feeling varies depending on the type of fiber and the knitting method, but underwear that directly contacts the skin, such as cotton knitted knitted underwear, nylon tricot slips, or a towel that is felt by the direct touch In such cases, there was a problem that a soft treatment gives a greedy feeling, or becomes extremely oily (oily). Further, when the treatment concentration of the softening agent is increased, the softening effect is increased, but this greedy feeling is further increased, and the softening effect and the greedy feeling are not obtained in the conventional softening agent composition using the quaternary ammonium salt. It has been considered to be correlated.

Under such circumstances, a softening agent composition in which a quaternary ammonium salt and various additives are used in combination, such as an acyclic quaternary ammonium salt, a specific polyquaternary ammonium salt and Softening agent containing a nonionic compound (Japanese Patent Publication No. 60-47384); Softening agent containing a quaternary ammonium salt, a cationic polyamide and a fatty acid glyceride (Japanese Patent Laid-Open No. 382372); Quaternary ammonium A softening finishing agent containing a salt, a fatty acid (salt) and a glyceride (JP-A-63-295764) has been proposed. However, as long as these softening finish compositions have a quaternary ammonium salt as an active ingredient, even if various additives are used in combination, the above-mentioned greedy feeling cannot be sufficiently solved. When the softening agent composition is treated at a relatively high concentration, there is a problem that it gives a marked discomfort.

Therefore, an object of the present invention is to rinse in a washing tub, which does not give a greedy feeling to the softening-treated fiber even in a high-concentration treatment and effectively imparts flexibility to both the natural fiber and the synthetic fiber. It is to provide a liquid softener composition for use in a bath.
