Description
(1)トルク
試料(捲縮糸)約70cmを横に張り、中央部に0.18mN×表示テックス(2mg/de)の初荷重を吊るした後、両端を引揃える。糸は残留トルクにより回転しはじめるが初荷重が静止するまでそのままの状態で持ち、撚糸を得る。こうして得た撚糸を17.64mN×表示テックス(0.2g/de)の荷重下で25cm長の撚数を検撚器で測定する。得られた撚数(T/25cm)を4倍にしてトルク(T/m)とする。
(2)インターレース度
交絡糸を8.82mN×表示テックス(0.1g/de)の荷重下で1mの長さをとり、除重後、室温で24時放縮後の結節点の数を読み取り、個/mで表示する。
(3)捲縮率
供試糸条を、周長が1.125mの検尺機のまわりに巻きつけて、乾繊度が3333dtexのかせを調製した。前記かせを、スケール板の吊り釘に懸垂して、その下部分に6gの初荷重を付加し、さらに600gの荷重を付加したときのかせの長さL0を測定する。その後、直ちに、前記かせから荷重を除き、スケール板の吊り釘から外し、このかせを沸騰水中に30分間浸漬して、捲縮を発現させる。沸騰水処理後のかせを沸騰水から取り出し、かせに含まれる水分をろ紙により吸収除去し、室温において24時間風乾する。この風乾されたかせを、スケール板の吊り釘に懸垂し、その下部分に、600gの荷重をかけ、1分後にかせの長さL1aを測定し、その後かせから荷重を外し、1分後にかせの長さL2aを測定する。供試フィラメント糸条の捲縮率(CP)を、下記式により算出する。
CP(%)=((L1a−L2a)/L0)×100
(4)目付け
JISL1018−1998 6.4により測定する。
(5)平均摩擦係数MIU、平均摩擦係数の変動MMD、表面粗さの平均偏差SMD
測定機器KES−FB4−A表面試験機で測定する。平均摩擦係数MIUは大きいほど滑り難い。平均摩擦係数の変動MMDは大きいほどざらつきが大きい。表面粗さの平均偏差SMDは大きいほど表面の凹凸が大きい。
(6)圧縮剛性LC、圧縮回復性RC
測定機器KES−FB3−AUTO−A圧縮試験機で測定する。圧縮剛性LCは1に近いほど圧縮硬い。圧縮回復性RCは100に近いほど回復性がよい。
(7)曲げ剛性B
測定機器KES−FB2−AUTO−A純曲げ試験機で測定する。曲げ剛性Bは大きいほど曲げ難い。
(8)拡散性残留水分率
20℃×65%RH下の雰囲気中で試料に約0.6gの水を滴下させ、各時間の質量を測定し、拡散性残留水分率を算出する。
残留水分率(%)=各時間の水分量(g)/滴下(裏面)直後の水分量(g)×100
残留水分率が10%以下になった時の時間を測定する。時間が短い方が良い(早い時間で乾く)。
(9)乾燥速度
水0.04gを滴下し30分後の水分率を測定する(基準20%以下)。水分率が小さい方が良い(早く水分が蒸発して乾く)。初期と、JIS L0217 103により5回洗濯したものについて測定する。
(10)通気度
JIS L1018−1990 6.34により通気度(cm3/cm2・s)を測定する。
(11)厚さ
JISL1018−1990 6.5により測定する。
(12)吸水性(吸汗性)
JIS L1096−1990 6.26吸水速度A法(滴下法)により測定する。
(13)撥水性
JIS L1092−2009 7.2スプレー試験法により撥水度(級)を測定する。
通常のポリエチレンテレフタレート(艶消し剤の含有率0.3重量%)を用いて通常の紡糸装置から280℃で溶融紡糸し、2800m/分の速度で引取り、延伸することなく巻取り、半延伸されたポリエステル糸条90dtex/72fil(単繊維の断面形状:丸断面)を得た。
