Benefits of technology

The invention provides a fiber for making artificial hair that can be easily curled with a hair iron and also easily combed afterward. This results in a better-looking, more natural-looking hair product.

Problems solved by technology

Heating can change the shape of the artificial hair but the shape cannot be fixed at the heating temperature.
When the cooling time was short, the artificial hair of Patent Document 1 had a poor curl setting property at the time of curling with a hair iron.

example 1

[0104]100 parts by weight of polyethylene terephthalate that was dried to a moisture content of 100 ppm or less, 20 parts by weight of brominated epoxy-based flame retardant, and 2 parts by weight of sodium antimonate were dry blended. The mixture obtained was supplied to a twin-screw extruder and melt kneaded at 280° C., and then was formed into pellets. The pellets obtained were dried to a moisture content of 100 ppm or less. Next, the dried pellets were supplied to a melt spinning machine, and a molten polymer was extruded through a spinneret with a nozzle having the shape indicated in Table 1 below at a barrel temperature of 280° C. The extruded polymer was passed through a heated tube, cooled to a temperature of not more than the glass transition temperature of the polyethylene terephthalate, and wound up at a speed of 60 to 150 m / min. Thus, spun yarns (undrawn yarns) were obtained. Fibers of Example 1 were obtained by configuring a nozzle hole in the nozzle having the shape in...

Abstract

The present invention relates to a fiber for artificial hair having a void in a center of a fiber cross section. A ratio of an area of the void to an entire area of the fiber cross section is 5% to 50%. The fiber cross section has a flat multilobed shape, and the void has a first side and a second side that are inclined 70 to 110 degrees relative to a major axis of the fiber cross section. The present invention also relates to hair ornament products including the above fiber for artificial hair. Thus, the present invention provides a fiber for artificial hair having a favorable curl setting property when curling with a hair iron and a favorable combing property after curling with a hair iron, and hair ornament products including the same.

Description

TECHNICAL FIELD[0001]The present invention relates to a fiber for artificial hair that can be used as an alternative to human hair. Specifically, the present invention relates to a fiber for artificial hair having a hollow in the center of a fiber cross section, and a hair ornament product including the same.BACKGROUND ART[0002]Conventionally, human hair has been used for hair ornament products such as hairpieces, hair wigs, hair extensions, hair bands, and doll hair. In recent years, however, the cost of human hair increases due to difficulty in obtaining human hair, which increases the importance of artificial hair that can be substituted for the human hair. Artificial hair for hair ornament products is required to have a curl property because it is curled with a hair iron. As artificial hair that can be curled with a hair iron, Patent Document 1, for example, describes artificial hair made of polyvinyl alcohol fibers with a shrinkage percentage under dry heat at 180° C. of 10% or...
