本発明の1の実施形態は、表層と裏層の表裏二層の編地と、該表裏二層の編地同士を連結する連結糸とを含み、該表裏二層の編地の少なくとも一方に複数の畝部と該畝部によって挟まれる凹部が形成されているダブルラッセル編地であって、該畝部は経方向に連なる編目列が2ウェール以上寄せ合って形成され、且つ該畝部がシンカーループによって少なくとも片側で隣り合う畝部と連結していることを特徴とする、ダブルラッセル編地である。
尚、表皮材としての性能を十分に発揮するためには縫目強度が500N以上であることが好ましく、又、形態保持の観点から、凹部の引張抵抗力を表す引張変形量が1.5mm以下であることが好ましい。
尚、表層の編地に用いる繊維がマルチフィラメントである場合、その単糸繊度は1デシテックス以上6デシテックス以下が好ましいが、単糸の強力がより高くなる3デシテックス以上6デシテックス以下がより好ましい。
以下、実施例等において用いたダブルラッセル編地の各種物性の測定方法は以下の通りのものであった。
キーエンス社製のワンショット3D測定マイクロスコープVR-3000を用い、倍率25倍~38倍で、得られたダブルラッセル編地の表層の編地の外側面をオートフォーカス、3D測定で撮影する。平面計測の2地点間距離機能を使用し、隣り合う編目列が隙間を開けて凹部を形成した隣り合う編目同士最短距離をマイクロスコープで測定し、最短のものを記録とする。測定は5カ所行い平均値を求める。凹部のコース数が5コース未満の場合は全ての隣り合う編目同士の最短距離を測定し、平均値を求める。
得られたダブルラッセル編地から試験片を幅100mm、長さ100mmの大きさでタテ・ヨコの合計2方向からそれぞれ2枚一組で三組準備する。2枚の試験片の長さ方向の向きを同一方向にして表側を重ね合わせ、端から6mmの位置を縫製する。縫製の際にはポリエステル#8のミシン糸とオルガン針KKの21番―Sのミシン針を使用し、縫目ピッチ25±2目/100mm条件で縫い合わせる。縫製した試験片はつかみ間隔76±1.0mmとし、表25.4×25.4mm、裏25.4mm×50.8mm幅の「つかみ」を使用して定速度伸長型の引張試験機に取り付ける。試験片を200mm/minで引張り、破断に要する荷重(N)を測定する。
得られたダブルラッセル編地から、タテ50mm、ヨコ260mmの試験片を3枚採取する。採取した試験片の隣り合う畝部の間隔を前記(a)項の方法で測定する。次に引張試験機を用いて、試験片を開いた状態でつかみ間隔100mmとしてつかみ、50mm/minの引張速度で147.1Nの荷重を与えた後、試験片をつかみから取り外し、1 時間保持後、再度前記(a)項の方法で隣り合う畝部の間隔を測定し、次式:
凹部の引張変形量(mm)=引張前の隣り合う畝部の間隔(mm)-引張後の隣り合う畝部の間隔(mm)
により凹部の変形量を算出し、3枚の平均値を結果とする。この引張変形量が小さいほど、凹部の引張抵抗力が高いことを示す。
得られたダブルラッセル編地の畝形状について目視にて評価し、以下の基準で等級判定を行い、形状安定性の評価とした。
○:畝形状の崩れなどがなく、明確に畝が形成されている
△:組織のずれなどでやや畝形状が崩れているが、意匠性に問題はない
×:畝形状が明らかに崩れ、意匠性に問題がある
