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む立体編物から構成される座席シート用表皮材であって、該立体編物は少なくとも一方の層に凹状変形部を有し、かつ、次式:
パラメータA=コース密度(コース/2.54cm)×凹部厚み(mm)/生地厚み(mm)
で算出されるパラメータAが6以上36以下であることを特徴とする、座席シート用表皮材である。
パラメータA=コース密度(コース/2.54cm)×凹部厚み(mm)/生地厚み(mm)
で算出されるパラメータAが6以上36以下であることが必要である。
パラメータAが6未満であると、表層の編み目が粗く、また、非変形部から変形部への厚みの変化が大きくなるために圧縮時の接触面積が小さくなり圧力が集中することで、面ファスナーのフック部等の突起物が表層の編目の単繊維に引っ掛かり易くなり、単繊維が切断され毛羽立ち易くなる。逆に、パラメータAが36を超えると、表層の編目の単繊維に面ファスナーのフック部等の突起物が引っ掛かり難くなるが、表層が平滑になるため着座者の臀部の滑りを抑制できず、また表裏二層の編地同士を連結する連結糸と生地厚み方向とで形成される角度が小さくなり、また凹状変形部において連結糸が固定されないことから、横倒れ現象が抑制できず、クッション性が悪化するものとなる。
突起物による毛羽立ちを抑える観点から、パラメータAの好ましい範囲は8以上であり、より好ましくは10以上である。また、着座者の臀部の滑りを抑止する観点と横倒れ現象を抑制することでクッション性をより良好にする観点からは、パラメータAの好ましい範囲は30以下であり、より好ましくは24以下である。
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、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。
突起物による毛羽立ちを抑える観点から、編目緻密度のより好ましい範囲は13000以上23000以下であり、さらに好ましくは14000以上23000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。
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。
立体編物のコース密度(コース数/2.54cm)を目視にて測定する。また、凹状変形部における厚み(mm),非変形部における厚み(mm)を測定する。ここで、前記立体編物が、厚みの異なる凹状変形部を複数有する場合、および、凹状変形部の位置によって厚みが異なる場合は、厚みが最小となる箇所を凹部厚みとする。また、生地厚みについては、凹状変形部による生地厚みへの影響が可能な限り小さい箇所における厚みを測定する。換言すると、立体編物の厚みが最大となる箇所を生地厚みとする。厚みは、厚さ測定器を用いて0.7kPa圧力下で測定を行う。また、凹状変形部における厚みは前記圧力を凹状変形部のみに加圧した際の厚みを測定する。
上記の通り測定したコース密度、凹状変形部における厚み、生地厚みを用いて、次式:
パラメータA=コース密度(コース/2.54cm)×凹部厚み(mm)/生地厚み(mm)
により、パラメータAを算出する。
立体編物の表層の編地から糸を抜き出し、表層の編地の1個の編目を形成する繊維の総繊度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。また、立体編物のコース数/2.54cmとウェール数/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。
立体編物を40cm×40cmのサイズにカットし、凹状変形部を無作為に1つ抽出し、目視にて該凹状変形部が形成されているウェール数を数える。この際、凹状変形部が複数のコースにまたがって形成されている場合、同一コース上のウェール数だけを数えるのではなく、複数コースにまたがった全体のウェール数を数える。
また、凹状変形部がカットした立体編地の全幅に渡っている場合は、該立体編み時の全幅のウェール数を、凹状変形部を形成するウェール数とする。
立体編物を40cm×40cmのサイズにカットし、凹状変形部を無作為に1つ抽出し、目視にて該凹状変形部を形成する同一ウェール上のコース数を数える。
立体編物を40cm×40cmのサイズにカットし、同一ウェール上で最も近接する凹状変形部を抽出し、該凹状変形部同士の編地経方向間隔を、定規を用いて目視にて測定する。
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、以下の基準で等級判定を行う。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
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。
本座席シートに着座したモニターがクッション性についてどう感じたかを、以下の基準で等級判定を行い、クッション性の評価とした。判定は0.5級きざみで行う。
5級:しっかりクッション性があり、快適である
4級:クッション性があり、やや快適である
3級:ややクッション性があるが、快適ではない
2級:わずかにクッション性があるが、やや不快である
1級:クッション性がなく、不快である
前記座席シートに着座したモニターが臀部の滑り性についてどう感じたかを、以下の基準で等級判定を行い、クッション性の評価とした。判定は0.5級きざみで行う。
5級:全く滑らず、グリップ性をしっかり感じる
4級:ほとんど滑らず、グリップ性を感じる
3級:やや滑りにくい
2級:やや滑りやすく、あまりグリップ性を感じない
1級:かなり滑りやすく、全くグリップ性を感じない
1辺の長さ40cmの正方形にカットした表皮材を、表層を上にして水平な机上に置き、上から手で押した際の横倒れ性について、以下の基準で等級判定を行い、横倒れ性の評価とした。判定は0.5級きざみで行う。
5級:全く横倒れしない
4級:やや横倒れする
3級:横倒れする
2級:かなり横倒れする
1級:極めて横倒れしやすく、圧縮後に回復しない
