本発明の実施例、比較例における測定方法は下記のとおりであり、記載していない測定方法は業界規格にしたがった。
<脱毛率>
脱毛率はJIS L 0217 103法に準じて測定した。
<乾燥試験>
・条件:試験実施は標準状態環境下、温度20±4℃、相対湿度65±4%RHで実施した。
・浸漬する水は、常温20℃±15℃(5~35℃)を使用した。
・温度・湿度コントロールのために、エアコンと除加湿機使用を適宜判断して使用した。・干す場所は一定とした。
・寸法、重量は実際に計測値した。
・時間はストップウォッチを使用して計った。
・操作
1.検体1枚ずつを常温の水を入れたバケツに、タオル全体が完全に水に浸っていることを確認してから浸漬2分間とした。
2.浸漬2分間後、30秒間持ち上げて自然水切りをした。
3.その後、脱水4分間とした。
4.脱水後、試験実施スタートまでの間はチャック付きの袋に検体毎入れて保管した。5.所定時間毎に検体の重量を測定した。
6.重量測定と同時刻の「温度、相対湿度」を記録した。
7.水分残留率が10%を切るまで、重量測定を所定時間毎に記録した。
<パイル保持性>
JIS L 1075 B法に準じて測定した。
<表面吸水法(ラローズ指数)>
JIS L 1907法に準じて測定した。ラローズ指数(吸水評価指数)は、下記の式に従って算出した。
ラローズ指数(吸水評価指数)=2545×吸水速度(ml/s)+吸水量(ml)+79
<圧縮試験>
Kato Tech社の圧縮試験機KES(Kawabata Evaluation System)-G5を使用し、20cm2の圧縮子、上限荷重は50gf/cm2、圧縮スピードは0.5mm/secで測定した。測定箇所は図7に示すように、タオル生地10の経糸11と緯糸12が交差しない位置とし、表面測定箇所13a,13bと裏面測定箇所14a,14bを測定した。
測定データには、WC(圧縮仕事量)、LC(圧縮直進性)、RC(圧縮回復性)がある。このうちWC値はタオルのやわらかさを示すことが官能試験で判明している。WC値は、図8のグラフにあるS1の面積である。WC値が大きいほど圧縮されやすい。すなわち、やわらかさがあることになる。図8において、Bはスタート時点、Aは押し込みの最大点、Cは押し込みの最大距離、pは押し込み時の荷重-距離曲線(実測データ)、qは回復時の荷重-距離曲線(実測データ)、S1は押し込み時の荷重-距離曲線pとB-CとA-C間の面積、S2は回復時の荷重-距離曲線qとB-CとA-C間の面積である。WC(圧縮仕事量)は押し込み時の面積S1と回復時の面積S2の合計面積であり、次の式によって求める。
WC=S1+S2
<かさ高性試験>
JIS L 1096.8.5(織物、編み物試験方法)及びISO 10012-1に規定されている厚み測定器(インテック社製、型式TH-2)を使用し、直径50.5mmのプレッサーフット、0.7KPaの荷重をかけ、10秒後の数値を測定した。測定箇所は図7に示すように、タオル生地10の経糸11と緯糸12が交差しない位置とし、表面測定箇所13a,13bと裏面測定箇所14a,14bを測定した。

但し、Bu:かさ高性(cm3/g)
Sm:標準状態における単位面積当たりの質量(g/m2)
t:厚さ(mm)

経パイル糸、経地糸及び緯地糸は無糊(ノーサイジング)とし、エアー織機に掛け、400r.p.m.で図2及び図3に示すループパイル生地織物を製造した。経パイル糸の供給倍率は経地糸の7.5倍とした。このようにして経糸密度60本/2インチ、緯糸密度42本/インチ、パイル長1.06cmの両面パイル生地を製造した。このパイル織物生地を精練漂白した後(糊抜きは不要)、テンターにかけて熱処理し、仕上げをした。この生地の単位面積当たりの質量(目付)は417g/m2であった。
紡績速度440m/min、長短複合紡績糸の単糸強力534.3cN、伸度4.35%とした以外は実施例1と同様に実施した。
経パイル糸として、コットン100%使いのリング紡績糸、綿番手16Sの単糸を使用し、サイジングをした以外は実施例1と同様にタオルを製織し、糊抜きした。
