ARTIFICIAL HAIR, METHOD FOR PRODUCING AN ACRYLIC FIBER FOR ARTIFICIAL HAIR, AND HEAD DECORATION PRODUCT COMPRISING THE ARTIFICIAL HAIR

The present invention relates to an acrylic fiber for artificial hair formed from an acrylic polymer. The acrylic polymer contains 29.5 to 79.5 wt% of acrylonitrile, 20 to 70 wt% of vinyl chloride and/or vinylidene chloride, and 0.5 to 5 wt% of a sulfonic acid-containing vinyl monomer with respect t...

Beschreibung
Zusammenfassung:	The present invention relates to an acrylic fiber for artificial hair formed from an acrylic polymer. The acrylic polymer contains 29.5 to 79.5 wt% of acrylonitrile, 20 to 70 wt% of vinyl chloride and/or vinylidene chloride, and 0.5 to 5 wt% of a sulfonic acid-containing vinyl monomer with respect to a total weight of the acrylic polymer. The content of an organic solvent that can dissolve the acrylic polymer in the acrylic fiber is 0.1 to 3 wt%. The acrylic fiber for artificial hair can be produced by: extruding a spinning solution containing the acrylic polymer through a spinning nozzle to form a yarn; drawing the yarn to prepare a primary drawn yarn and washing it with water; and impregnating the water-washed primary drawn yarn with an organic solvent that can dissolve the acrylic polymer. Thus, the present invention provides an acrylic fiber for artificial hair having favorable curl setting properties with hot water, a method for producing the same, and a hair ornament product including the same.
