Description
上記熱可塑性樹脂の融点は１８０℃以上、２８０℃以下が好ましい。
本発明において、島部は、海部の海成分に覆われており、通常のプレセットやファイナルセット等の後加工における乾熱処理でも問題のない良好な耐熱性を備えている。島成分の融点が低過すぎると、乾熱処理により、島部の融解が生じ易くなる傾向がある。また高過ぎると、海成分との複合紡糸が難しくなる傾向がある。よって、耐熱性、安定した製糸性や海部と島部との剥離を抑制し易い点から、上記の範囲が好ましい。より好ましい上記熱可塑性樹脂の融点は、２１０℃以上、２７０℃以下であり、さらに好ましくは２２０℃以上、２６５℃以下である。
The melting point of the thermoplastic resin is preferably 180 ° C. or higher and 280 ° C. or lower.
In the present invention, the island part is covered with sea components of the sea part, and has good heat resistance without any problem even in the dry heat treatment in post-processing such as a normal preset or final set. When the melting point of the island component is too excessive low, the dry-heat treatment tends to melt easily occurs of islands. Moreover, when too high, there exists a tendency for the composite spinning with a sea component to become difficult. Therefore, the above range is preferable from the viewpoints of heat resistance, stable yarn production, and easy suppression of peeling between the sea and the island. The melting point of the thermoplastic resin is more preferably 210 ° C. or higher and 270 ° C. or lower, and further preferably 220 ° C. or higher and 265 ° C. or lower.
このようにして得られた本発明の海島型複合繊維は、製糸安定性が良好で、耐熱性も良好なため、延伸工程、仮撚工程、製編織工程、精練工程、染色工程等の各工程でも、剥離しにくく、各工程での取り扱い性に優れる。特に、染色の際に、色斑が生じて染色性が悪化したり、白化現象が生じたりしないため、色斑がなく濃色に染色ができる。また、適宜、調整することにより、目的に応じて、良好な軽量性や撥水性を容易に得ることができる。 Islands-in-sea type composite fiber of the present invention obtained in this way, reeling stability is good, because heat resistance good, stretching step, false twisting process, knitting weaving process, spinning kneading step, each such dyeing process Even in the process, it is difficult to peel off, and the handleability in each process is excellent. In particular, during the dyeing, color spots are not generated and the dyeability is not deteriorated, and the whitening phenomenon does not occur. Moreover, by adjusting suitably, favorable lightweight property and water repellency can be obtained easily according to the objective.
（８）染色性評価
得られた海島型複合繊維で作製した筒編地を、７０℃で２０分間の精練を行い、水洗、風乾し、分散染料（ダイアニックス（登録商標） ブルー ＡＣＥ）２．０％ｏ．ｗ．ｆ、浴比１：５０、１３０℃で１時間の高圧染色後、還元洗浄を常法で行い、下記の基準により評価した。
○：色斑や白化現象がない場合
△：色斑はあるが白化現象がない場合
×：白化現象がある場合
(8) a tubular knitted fabric produced in dyeability evaluation obtained sea-island type composite fiber, performs a fine mixing for 20 minutes at 70 ° C., washed with water, air dried disperse dye (Dianix ® Blue ACE) 2 0.0% o. w. f, bath ratio 1:50, after high-pressure dyeing at 130 ° C. for 1 hour, reduction washing was carried out by a conventional method and evaluated according to the following criteria.
○: When there is no color spot or whitening phenomenon △: When there is color spot but no whitening phenomenon ×: When there is whitening phenomenon
