Description
(1)表皮層用樹脂液を離型性基材上に塗布して、ポリウレタン樹脂からなる表皮層を形成する工程、
(2)表皮層と繊維質基材とを貼り合わせる工程、
(3)離型性基材を剥離する工程、及び、
(4)ポリウレタン樹脂、固体のシリコーン系化合物および低流動性液体のシリコーン系化合物を含有する表面処理層用樹脂液を表皮層上に塗布して、表面処理層を形成する工程。
[耐白化性]
本試験は、シート上での人の動き(上下動、前後動、ツイスト運動)を再現する臀部模型を備えるロボットによって行った。
具体的には、温度20±2℃、湿度65±5%RHの状況下で、臀部模型上に試験片を配置し、荷重が77kg重(754.6N)、臀部模型の上下動(50mm)と前後動(30mm)とツイスト運動(15度)をこの順で25万回繰り返し摩耗した。摩耗後の試験片を目視で確認し、下記の基準に従って判定した。
○:表面に変化が認められない
△:若干白化現象が認められるが目立たない
×:明らかに白化現象が認められる
幅70mm、長さ300mmの大きさの試験片をタテ、ヨコ各方向からそれぞれ1枚採取し、裏面に幅70mm、長さ300mm、厚み10mmの大きさのウレタンフォームを添えて、平面摩耗試験機T−TYPE(株式会社大栄科学精器製作所製)に固定した。綿布(綿帆布)をかぶせた摩擦子に荷重9.8Nを掛けて試験片を摩耗した。摩擦子は試験片の表面上140mmの間を60往復/分の速さで20000回往復摩耗した。その際、摩耗回数2500回往復ごとに綿帆布を交換し、合計20000回往復摩耗した。摩耗後の試験片を観察し、下記の基準に従って判定した。
5:表皮層に亀裂や削れ、破れがない
4:表皮層に若干亀裂が発生した
3:表皮層に亀裂が発生した
2:表皮層に亀裂、および、削れまたは破れが発生した
1:表皮層が欠落し、繊維質基材が見える
(表皮層の形成)
ポリカーボネート系ポリウレタン樹脂(商品名「クリスボンNY−328」、DIC株式会社製)100質量部に対して、ジメチルホルムアミド40質量部を加え、粘度約2000mPa・sに調整して表皮層用ポリウレタン樹脂液を作製した。該ポリウレタン樹脂液を離型紙へ塗布厚200μmになるようにコンマコーターにてコーティングした後、130℃で2分間乾燥し、ポリウレタン樹脂からなる表皮層を得た。
ポリカーボネート系ポリウレタン接着剤(商品名「クリスボンTA−205」、DIC株式会社製)100質量部に対して、ジメチルホルムアミド50質量部を加え、粘度約4500mPa・sに調整して接着層用樹脂液を作製した。該樹脂液を、上述の表皮層に塗布厚200μmになるようにコンマコーターにてコーティングした後、100℃で1分間乾燥した。
接着層の表面とトリコット編地を合わせて39.2kPa条件下で1分間プレス圧着した後、離型性基材を剥離して、厚さ40μmのポリウレタン樹脂からなる表皮層を有する積層体を得た。
下記の処方1に従い調製した表面処理層用ポリウレタン樹脂液を、上述の表皮層表面にリバ−スコータ−にてコーティングした後、130℃で2分間乾燥し、厚さ15μmの表面処理層を形成し、実施例に係る合成皮革を得た。なお、表面処理層用ポリウレタン樹脂液の粘度は、3200mPa・s(B型粘度計、ローター:No4、60rpm、23℃)であった。
