Embodiment
[0087] Although an Example and a comparative example are shown below and the specific embodiment of this invention is demonstrated in more detail, this invention is not limited only to this Example.
[0088] Raw materials used in Examples and Comparative Examples are shown below.
[0089] (polyvinyl chloride resin (A))
[0090] A-1: an independent polymer of vinyl chloride, with a viscosity-average degree of polymerization of 500 (TH-500 manufactured by Taiyang Polyvinyl Chloride Co., Ltd.).
[0091] A-2: An independent polymer of vinyl chloride, the viscosity-average degree of polymerization is 1100 (TH-1000 manufactured by Taiyang Polyvinyl Chloride Co., Ltd.).
[0092] A-3: A single polymer of vinyl chloride, with a viscosity-average degree of polymerization of 1350 (TH-1400 manufactured by Taiyang Polyvinyl Chloride Co., Ltd.).
[0093] A-4: An independent polymer of vinyl chloride, the viscosity-average degree of polymerization is 2000 (TH-2800 manufactured by Taiyang P...
Embodiment 2~19、 comparative example 1~10
[0106] Examples 2 to 19 were obtained in the same manner as in Example 1, except that the compounding of the polyvinyl chloride-based resin composition and the cross-sectional shape of the fibers obtained by melt spinning were changed as shown in Tables 1 to 3. Fibers for artificial hair of Examples 1-10.
Embodiment 20、21
[0108] In addition to the length L of the first protrusion 1 , the length L of the second protrusion 2 and the length L of the third protrusion 3 All were set to 78 μm or 75 μm, and the fibers for artificial hair of Examples 20 and 21 were obtained in the same manner as in Example 1.
[0109] [Evaluation]
[0110] About the fiber for artificial hair of an Example and a comparative example, spinnability, low glossiness, and the grip property at the time of weaving were evaluated based on the following evaluation methods and reference|standard. The results are shown in Tables 1-4.
[0111] (1) Spinnability
[0112] While melt spinning was performed to form an undrawn yarn, the state of occurrence of yarn breakage was visually observed and evaluated on a 5-point scale as follows.
[0113] 1: Yarn breakage was 10 to 15 times / 1 hour.
[0114] 2: Yarn breakage was 7 to 9 times / 1 hour.
[0115] 3: Yarn breakage was 4 to 6 times / 1 hour.
[0116] 4: Yarn breakage was 2 to 3 tim...
