Description
[実施例1]
固有粘度が0.95のポリエチレンテレフタレートと固有粘度が0.64のポリエチレンテレフタレートとを、図1に示す2成分ポリマーの同時紡糸が可能な設備を用い、それぞれを表1記載の温度で押出機にて溶融後、紡糸パックに融液を供給した。その際、高固有粘度側:低固有粘度側の吐出重量比が8:2となるようにし、かつ延伸後の総繊度が78dtexとなるように計量後、温度295℃の紡糸口金より吐出した。吐出された糸条は、冷却後インターレースノズルにて交絡数10ケ/mとなるように交絡処理を施し、1000m/分の速度にて巻き取った。
実施例1において、高固有粘度側のポリエステルの溶融温度を293℃とし、表2記載の条件で紡糸延伸する以外は実施例1と同様にした。得られた混繊糸の評価結果を表2に示す。なお、ポリエステルの溶融粘度が高くなりすぎて紡糸安定性は低下した。
