また、ポリプロピレン繊維は、前記成分(A)、成分(B)及び成分(C)を含む熱可塑性樹脂組成物が少なくとも繊維表面に配される限り、芯鞘構造或いは貼合わせ構造等の複合繊維であってもよく、溶融紡糸において複合紡糸することもできる。
次の評価基準により判定した。
◎:糸径斑(脈動)が全くなく、良好に紡糸可能
○:糸径斑(脈動)が殆どなく(48フィラメント中1〜5本)、良好に紡糸可能
△:紡糸可能なるも、糸径斑(脈動)が多数発生(48フィラメント中6本以上)
×:糸切れ多発により紡糸不可能
下記のように、得られたポリプロピレン繊維で製編した編地にて染色性を評価した。

浴比1:50
4℃/分で昇温、100℃×30分
染色後、エマルゲン909(花王社製界面活性剤)1g/Lでソーピング、水洗、風乾
b.評価サンプルによる染色性評価
次の評価基準により目視判定
○:濃色に染色
△:表面に着色するが、染色良好とはいえない
×:全く着色しないか汚染程度の着色
JIS L 1013 8.5.1(標準時試験)に準拠し、オリエンテック社製テンシロン RTC=1210Aにて測定した。
飽和ポリエステル樹脂−1(イソフタル酸30モル%共重合のイソフタル酸変性ポリブチレンテレフタレート、以下、PBT−1と略記)の製造;
内部を窒素雰囲気下とした重合反応釜に、ジメチルテレフタレート(以下、DMTと略記)とジメチルイソフタレート(以下、DMIと略記)をモル比で70:30になるように投入し、次いで1,4−ブタンジオール(以下、BDOと略記)を、DMTとDMIの合計仕込量とBDOの仕込量とがモル比で1:1.4になるように投入し、さらに触媒としてテトラブトキシチタンをDMT、DMI及びBDOの総量に対して600ppm添加した後、釜内温度を240℃まで昇温してエステル化を行い、続いて釜内温度を260℃まで昇温すると同時に釜内圧力を0.15kPa以下に減圧し所定の重合度まで120分間重合を行った。その後、室温、常圧まで戻した後ポリマーを窒素加圧によりストランド状に水中に押し出すことにより重合を停止させ、水中で洗浄した後切断してチップ化し、120℃にて8時間減圧下で乾燥した。
飽和ポリエステル樹脂−2(イソフタル酸20モル%共重合のイソフタル酸変性ポリブチレンテレフタレート、以下、PBT−2と略記)の製造;
参考例1において、DMTとDMIの仕込み比を80:20とした以外は、参考例1と同様にしてイソフタル酸変性ポリブチレンテレフタレートを製造し、またその同定を行った。得られたPBT−2の融点は、192℃であった。
飽和ポリエステル樹脂−3(イソフタル酸10モル%共重合のイソフタル酸変性ポリブチレンテレフタレート、以下、PBT−3と略記)の製造;
参考例1において、DMTとDMIの仕込み比を90:10とした以外は、参考例1と同様にしてイソフタル酸変性ポリブチレンテレフタレートを製造し、またその同定を行った。得られたPBT−3の融点は、209℃であった。
変性ポリプロピレン樹脂−1(以下、変性PP−1と略記)の製造;
ポリプロピレンホモポリマーの粉末(JIS K 7210に準拠して測定した230℃のMFR:0.85g/10分、融点約164℃)100質量部に対し、2−ヒドロキシエチルメタクリレート5質量部、スチレン5.5質量部、1,3−ビス(2−t−ブチルパーオキシイソプロピル)ベンゼン1質量部を加え、スーパーミキサーで混合した後、1軸押出機を用いて、シリンダー温度220℃、スクリュー回転数約90rpmの条件で混練して変性ポリプロピレン樹脂のペレットを得た。このペレットのMFRは30g/10分であった。得られたペレット0.3gをキシレン20mlに入れ、110℃で完全に溶解させた後、メタノール150ml中に注ぎ、沈殿物として析出させ、これをろ過して取り出し、再度メタノールで洗浄、ろ過した後、減圧乾燥させることにより精製した変性ポリプロピレン樹脂−1を得た。この変性ポリプロピレン樹脂−1における2−ヒドロキシエチルメタクリレートとスチレンの含量を求めた。2−ヒドロキシエチルメタクリレートの含量は、赤外線分光分析法によりカルボニルに由来する1734cm−1のピークで予め検量線を作成し、これを用いて定量した結果、1.4質量%であった。また、スチレンの含量は、1−置換ベンゼンに700cm−1のピークで予め検量線を作成し、これを用いて定量した結果、1.4質量%であった。
参考例1〜3の飽和ポリエステル樹脂(PBT−1〜3)、参考例4の変性ポリプロピレン樹脂(変性PP−1)及びポリプロピレンホモポリマー(日本ポリプロ社製SA03、融点165℃、以下、未変性PPと略記)を用い、表1、表2に示す配合組成比に従って2軸押出機に投入し、220℃の条件で均一に混練し、ペレット状に溶融賦型した。
