Description
L/S1=1.1以上2.0以下 (1)
Lc/Sc1=1.3以上2.0以下 (2)
芯部又は鞘部に用いた水分量1000ppm以下に乾燥したペレット状の樹脂組成物の溶融粘度を、サンプル量20cc、ピストンスピード200mm/min、キャピラリー長20mm、キャピラリー径1mmの条件で、繊維化時の温度、すなわち紡糸時のノズル温度を設定温度として測定した。
オートバイブロ式繊度測定器「DENIER COMPUTER タイプDC-11」(サーチ社製)を使用して測定し、30個のサンプルの測定値の平均値を算出して単繊維繊度とした。
室温(23℃)にて、繊維を束ね、繊維束がズレないように収縮チューブで固定した後、カッターで切断し、その際の芯部の露出の有無を、目視にて評価、あるいは、切断した繊維断面をレーザー顕微鏡(株式会社キーエンス社製、「VK-9500」)にて観察し評価した。
室温(23℃)にて、繊維を束ね、繊維束がズレないように収縮チューブで固定した後、カッターで輪切りにし、断面観察用繊維束を作製した。この繊維束をレーザー顕微鏡(株式会社キーエンス社製、「VK-9500」)にて500倍の倍率で撮影し、繊維断面写真を得た。繊維断面写真に基づいて、L/S1及びLc/Sc1を求めた。
専門美容師による官能評価を行い、以下の4段階の基準で評価した。
A:人毛と同等の非常に良好な触感
B:人毛に比べやや劣るが良好な触感
C:人毛に比べ劣る悪い触感
D:人毛に比べ大きく劣る悪い触感
カールを完全に伸ばした状態で、繊維を長さが63.5cmになるように切断し、得られた繊維長が63.5cmの繊維5.0gを束ねた。その後、繊維束の中央を紐で括り、2つ折りにして紐の部分を固定して、ヘアーアイロン加工用の繊維束を作製した。次に、180℃に加熱したヘアーアイロン(米国IZUNAMI.INC社製、「IZUNAMI ITC450 フラットアイロン」)にて、繊維束を固定している根元から毛先までを圧着しながら加熱する操作を5回繰り返し、櫛通り性評価用の繊維束を作製した。その後、髪梳き用の櫛(ドイツ製、「MATADOR PROFESSIONAL 386.8 1/2F」)にて、櫛通り性評価用の繊維束を固定している根元から毛先まで100回櫛を通し、変形あるいは分裂した繊維の数から、以下の基準にて櫛通り性を評価し、B以上を合格とした。
A:櫛を100回通して変形あるいは分裂した繊維は10本未満で、最後まで抵抗なく櫛が通るレベル
B:櫛を100回通して変形あるいは分裂した繊維は10本以上30本未満で、途中で抵抗がやや強くなるが櫛は通るレベル
C:櫛を100回通して変形あるいは分裂した繊維は30本以上100本未満で、途中で抵抗が強くなり、櫛の通らないことが1回以上20回未満の確率で発生するレベル
D:櫛を100回通して変形あるいは分裂した繊維は100本以上で、途中で抵抗が強くなり、櫛の通らないことが20回以上の確率で発生するレベル
