Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a softening agent for fibers. More specifically, it relates to a softening / smoothing agent for fibers, which can be used for various fiber yarns and can impart excellent flexibility and smoothness regardless of their history of processing.

[0002]

2. Description of the Related Art Conventionally, as a softening agent for fibers, a combination of an aqueous wax emulsion and a surfactant (softening agent) is generally used. As the softening agent, fluorescent bleaching is used. For bleaching, anionic soft base for maintaining whiteness; dye-fixing agent dyed in a light color for untreated fibers Cationic soft base; fiber dyed in a dark color and treated with a dye-fixing agent Anionic and nonionic soft bases are used separately. In addition, an anionic surfactant containing a polyoxyethylene chain having 6 mol or more of ethylene oxide such as a higher alcohol or an ethylene oxide adduct sulfate ester salt of an alkylphenol, which can be commonly used in each treatment state of the fiber, An oil agent for fiber treatment, which comprises a wax, a nonionic surfactant and a cationic softening agent, has been proposed (JP-A-4-136270).

[0003]

However, the conventional softening and smoothing agents have a problem in that it is necessary to properly use the softening agent depending on the processing state of the fiber, which complicates the process control and inventory control. Further, the oil treatment for fiber treatment of the above-mentioned reference,
Since an anionic surfactant containing a polyoxyethylene chain added with 6 mol or more of ethylene oxide in one molecule is used, there is a problem that sufficient flexibility and smoothness cannot be obtained. .
