弾性回復率=自動車用カーペット熱成形後のフィラメントのパイル(パイル層)の高さ/自動車用カーペット熱成形前のフィラメントのパイル(パイル層)の高さ
ポリエチレンテレフタレート重合物を固状重合を実施し、液状重合物の分子量を上げる。一般的な固状重合の過程の中、バッチ固状重合機を用いて、真空条件下で140℃、4時間で水分除去のための乾燥を進め、235℃まで4時間から6時間にかけて昇温を施し、235〜245℃の温度範囲で実施例それぞれの最終目標分子量まで固状重合を実施した。また、ポリエチレンテレフタレート重合体にカーボンブラックを30重量%投入し、前記ポリエチレンテレフタレート重合物の固相重合温度の条件より低い温度の条件で固相重合を実施し、それぞれの最終目標の重量平均分子量まで固相重合を実施することにより、着色用マスターバッチチップを製造した。
原糸の固有粘度、重量平均分子量、分子量分布、CEG及びDEGの含量と着色用マスターバッチ重合物の重量平均分子量、分子量分布、DEG含量を下記表1に記載されたように調整したことを除いては、実施例1-1と同一な過程を経てポリエチレンテレフタレートBCF原糸及びカーペットをそれぞれ製造した。
1)重量平均分子量、分子量分布及び低分子物質の含量
原糸及び着色用マスターバッチをそれぞれヘキサフルオロイソプロパノール(HFIP)に溶解した後オルト-クロロフェノール(OCP)0.1wt%の希釈溶液をゲル透過クロマトグラフィー(Gel Permeation Chromatography)を用いて、低分子物質の含量、数平均分子量と重量平均分子量を測定した後、分子量の分布は数平均分子量に対する重量平均分子量の相対値で示した。
原糸及び着色用マスターバッチのカルボキシル末端基(CEG、Carboxyl End Group)は、ASTM D664及びD4094の規定により、試料0.2gを50mLの三角プラスクに入れた後、ベンジルアルコール20mLを加え、ホットプレート(hot plate)を利用して180℃まで上げ、5分間保持して試料を完全に溶解させた後、160℃に冷却して135℃に達した時に、フェノールプタルレン5〜6滴を加え、0.02N KOHで滴定し無色でピンクに変わる滴定点で下記の計算式1によってCEG含量(COOH million equiv./試料kg)を計算した。
[計算式1]
CEG=(A-B)×20×1/W
上記計算式1において、Aは試料の滴定に消費されたKOHの量(mL)であり、Bは空試料の滴定に消費されたKOHの量(mL)であり、Wは試料の重さ(g)である。
強度、伸度等の既存の繊維物性を適用せずに熱を加えながら応力(stress)を与える分析方法であるDMA(Dynamic Mechanical Analysis)を用いて、バルキー連続フィラメントの物性を測定する弾性モジュラス(Elastic modulus)概念を導入して、その結果を表1に図示しており、これにより、自動車用カーペットのパイルの回復率を測定及び予想することができる。
比較例1、2の場合、マスターバッチ内に臨界分子量以下の低分子物質が多数分布することによって、フィラメントの物性が低下したことがわかる。また、比較例2のフィラメント及びマスターバッチ重合物の重量平均分子量が比較例1よりも高くても、相対的に高いCEG又はDEG含量で熱に敏感な特性を有するため、弾性モジュラスの値には大きな差がないことをわかる。また、図4を参照すると、比較例1に基づいて製造された自動車用カーペットは、物性が不足して損傷を受けたことを確認することができ、実施例に基づいて製造された自動車用カーペットは、比較例に比べクッション感及びボリューム感に優れたことがわかる。
