本発明の1の実施形態は、表層の編地と、裏層の編地と、該表層の編地と該裏層の編地とを連結する連結糸からなる連結層とを含む立体編物から構成される表皮材であって、該表層の編地の外側面を人体と接する面とし、かつ、該表層の編地の編目緻密度が11500以上20000以下であることを特徴とする表皮材である。
本実施形態の表皮材を構成する立体編物は、表皮材の人体と接する面側となる表層の編地の編目緻密度が11500以上20000以下であることが必要である。
本明細書中、用語「編目緻密度」とは、下記式:
編目緻密度M=N×√D
{式中、Nは、2.54cm角当たりの表層の編地の編目数(個)であり、Dは、表層の編地の1個の編目を形成する繊維の総繊度(デシテックス)である。}で表される表層の編地の編目の緻密状態を示す指標である。尚、「表層の編地の1個の編目を形成する繊維の総繊度」とは、連結糸の繊度を除外すると共に、挿入編み等の編目を形成しない繊維を除外した、編目を形成する繊維のみの総繊度を指す。また、「人体と接する面」とは、表皮材を乗物や家具等の座席シートや乗物の内装材として使用した場合に、人体と接することになる面を指しており、座席シート用途の場合は着座面である。
突起物による毛羽立ちを抑え、清涼感、蒸れ感をより良好にする観点から、編目緻密度の好ましい範囲は13000以上19000以下であり、より好ましくは14000以上19000以下である。
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。
D1/D2≧3
を満たすことが好ましい。
本実施形態でいうメッシュ組織の開口部とは、表層の編地を形成するタテ方向に連なる編目列において、一部の又は全てのコースで、隣り合う編目列がコース方向(ヨコ方向)に0.3mm以上に隙間を開けることで形成される空隙のことをいい、メッシュ組織の開口部のサイズは、該メッシュ組織の開口部において、コース方向(ヨコ方向)の水平線で最も直線距離が長くなる2点を直線で結んだ長さを示す。図1に、隣り合う編目1、2の間に、サイズK(mm)のメッシュ組織の開口部3が形成されている状態を示す模式図を示す。尚、該メッシュ組織の開口部を横切るように糸が挿入編みされていてもよい。
以下、実施例等において用いた立体編物の各種物性の測定方法は以下の通りのものであった。
立体編物の表層の編地から10cm以上の糸を抜き出し、15gfの荷重を1本の糸に掛けた時の長さと重量を測定し、1本の糸の繊度を計算する。表層の編地の1個の編目を形成する繊維が2本以上の糸から形成されている場合は、それぞれの糸の繊度を計算して合計することで、総繊度D(デシテックス)を測定する。この際、連結糸は含まないようにする。尚、立体編物を編成する前に表層の編地の編目を形成する繊維の繊度を測定することが可能なものは、JIS L 1013に準拠して測定する。また、立体編物のコース数/2.54cmとウエール数/2.54cmの積Nを測定し、表層の編地の編目緻密度を下式:
編目緻密度M=N×√D
により算出する。
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倍で立体編物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。撮影された3D画像の表層の編地の最表層面を任意の高さでスライスした繊維の断面積の面積率(繊維の存在する面積の比率)の合計が0.3~0.5%となるように、高さ閾値を設定し、この高さを表側編地の外側面(最表層)の高さとする。続いて、外側面の高さから内側に向かって250μm下げた位置の繊維の断面積の面積率の合計を計測し、100%から本面積率を引いた値を、外側面から内側に向かって深さ250μmにおける開口率とする。
前記(b)で撮影された3D画像より、メッシュ組織の開口部において、コース方向(ヨコ方向)の水平線で最も直線距離が長くなる2点を直線で結んだ長さを測定し、メッシュ組織の開口部のサイズとする。測定は任意の開口部を20個所測定し、平均値を求める。
高山リード社製の通気性試験機FX3300ラボエアーIVを用い、試験片サイズ15cm角の立体編物の表層の編地を下側にして通気性試験機の開口部に置き、裏層の編地の外側面に厚さ3mm、20cm角のシリコンラバープレートを重ね、その上から通気性試験機のテストヘッドを押し当ててクランプで固定し、JIS L1096通気性試験方法(A法)に準じた吸引条件で、立体編物の4辺の断面の連結層から入り表側編地を透過する通気度を測定する。
高山リード社製の通気性試験機FX3300ラボエアーIVを用い、JIS L1096通気性試験方法(A法)に準じて立体編物の裏層の編地から表層の編地に透過する通気度を測定する。
大栄科学精器製作所製の平面摩耗試験機を用い、試験片サイズ幅8cm、長さ31cmの立体編物を、表層の編地を上側にして平面摩耗試験機の平面摩耗台に置いて両端をクランプで固定する。次に、クラレファスニング社製のマジックテープ(登録商標)A8693Y.71(長さ5cm)を、フック側を外側にして摩擦子に貼り付ける。摩擦子を含めて押圧荷重を9.8N、ストロークを14cm、速度を60±10往復/minとして、摩擦子を試験片の上に乗せて、往復5回の摩耗試験を行う。試験片は立体編物のタテ方向およびヨコ方向から採取して測定し、試験後に試験片の表面の摩耗状態を観察し、以下の等級判定を行う。判定は0.5級きざみで行う。
5級:毛羽立ちが認められない
4級:毛羽立ちがわずかに認められる
3級:毛羽立ちが明らかに認められるが、糸切れは目立たない
2級:毛羽立ちがやや著しく、糸切れや糸の「引き出され」がある
1級:毛羽立ちが著しく、外観異常が激しい
JASOM403 A法(テーバーロータリーアブレッサ法)に準じ、テーバー型摩耗試験機を用い、CS-10の摩耗輪により荷重4.9N、速度70rpmで1000回摩耗する。試験後に試験片の表面の摩耗状態を観察し、以下の等級判定を行う。判定は0.5級きざみで行う。
5級:表面状態に変化がない
4級:やや毛羽立ちがある
3級:毛羽立ちが多い
2級:毛羽立ちが多く糸が細くなっている
1級:糸切れがある
表皮材を、自動車用座席シートの座部、背部のウレタンパッド上に張り、座席シートの人体に接する全面が立体編物からなる表皮材で形成された座席シートを作製した。
本座席シートを30℃、50%RHの温湿度環境に設置し、モニターが本環境で30分間安勢にした後、座席シートに10分間着座した。この際、着座前に対して10分後にモニターが暑く感じたかどうかを、以下の等級判定を行い、清涼感の評価とした。判定は0.5級きざみで行う。モニターの数は5名とし、5名の平均値を求めた。

6枚筬を装備した18ゲージ、釜間4.2mmのダブルラッセル編機を用いた以外は、実施例4と同様にして、以下の表1の諸物性を有する立体編物を得、これを表皮材とした。
実施例4では、連結糸の編目数を実施例3対比1/2としたことにより、立体編物の連結層側から表層の編地に向かって透過する通気度が実施例3より大きくなり、清涼性、蒸れ感防止性がより良好となった。
これに対し、編目緻密度が11500未満である比較例1、2では、清涼感、および蒸れ感防止性は良好であるものの、外側面(最表層)から内側に向かって深さ250μmにおける開口率が大きいことも起因して、面ファスナーによる毛羽立ち性が著しいものであった。
また、比較例3は編目緻密度が高過ぎ、面ファスナーによる毛羽立ち性は抑制されているものの、立体編物の裏層の編地から表層の編地に透過する通気度、及び連結層側から表層の編地に向かって透過する通気度が低く、清涼性、蒸れ防止性に劣るものであった。
また、メッシュ組織の開口部のサイズが比較的小さい実施例9は、実施例10と比較して、面ファスナーによる毛羽立ち性がより良好となるものであった。
