Artificial hair fiber bundle and hair decorative product using the same
View Patent ↗An artificial hair fiber bundle comprising: a mixture of a synthetic acrylic base fiber (A) made of an acrylic base copolymer containing acrylonitrile, vinyl chloride and vinylidene chloride and a first vinyl monomer copolymerizable therewith, a synthetic acrylic base fiber (B) made of an acrylic base copolymer containing acrylonitrile, vinyl chloride and a second vinyl monomer copolymerizable therewith; a synthetic polyvinyl chloride base fiber having a monofilament fineness of 30 to 90 decitexes, provides a hair decorative product superior in stylability and sensory characteristics and favorable for use as a wig, hairpiece, or the like.
1. An artificial hair fiber bundle, comprising a mixture of:
a total amount of 20 to 80 wt parts of
a synthetic acrylic base fiber (A) made of an acrylic base copolymer containing 30 to 65 wt % of acrylonitrile, 35 to 70 wt % of vinyl chloride and vinylidene chloride, and 0 to 10 wt % of a first vinyl monomer copolymerizable therewith, and
a synthetic acrylic base fiber (B) made of an acrylic base copolymer containing 30 to 65 wt % of acrylonitrile, 35 to 70 wt % of vinyl chloride, and 0 to 10 wt % of a second vinyl monomer copolymerizable therewith; and
an amount of 20 to 80 wt parts of
a synthetic polyvinyl chloride base fiber having a monofilament fineness of 30 to 90 decitexes.
2. The artificial hair fiber bundle according to claim 1 , wherein the synthetic acrylic base fiber (A) is made of an acrylic base copolymer containing 40 to 60 wt % of acrylonitrile, 2 to 10 wt % of vinyl chloride, 30 to 60 wt % of vinylidene chloride, and 0.7 to 8 wt % of the first vinyl monomer copolymerizable therewith.
3. The artificial hair fiber bundle according to claim 1 , wherein the synthetic acrylic base fiber (A) has surface irregularity on a fiber surface, which has a surface irregularity depth of 5.0 to 15.0 μm and a convex distance of 0.05 to 0.5 mm, and has a flexural rigidity of 7.0×10 −7 to 10.0×10 −7 N·m 2 /m and a torsion rigidity of 5.0×10 −9 to 10.0×10 −9 N·m 2 .
4. The artificial hair fiber bundle according to claim 1 , wherein the synthetic acrylic base fiber (A) has a monofilament fineness of 20 to 70 decitexes and is mixed in the fiber bundle in an amount of 10 to 50 wt parts.
5. The artificial hair fiber bundle according to claim 1 , wherein the synthetic acrylic base fiber (B) is made of an acrylic base copolymer containing 40 to 60 wt % of acrylonitrile, 40 to 60 wt % of vinyl chloride, and 0.7 to 8 wt % of the second vinyl monomer copolymerizable therewith.
6. The artificial hair fiber bundle according to claim 1 , wherein the synthetic acrylic base fiber (B) has a monofilament fineness of 20 to 70 decitexes and is mixed in the fiber bundle in an amount of 10 to 70 wt parts.
