(合成樹脂表皮材の評価:凹凸模様の維持性)
得られた合成樹脂表皮材10において、絞模様が形成されたフッ素樹脂含有層16の表面粗さを、表面粗さ計(東京精密製、サーフコム130A)にて測定した。
その後、合成樹脂表皮材10におけるフッ素樹脂含有層16の表面が130℃になるまで加熱し、加熱後のフッ素樹脂含有層16の表面について、表面粗さを、加熱前の合成樹脂表皮材10と同様の条件で測定し、加熱前後の表面粗さを対比して、以下の式により凹部深さ保持率を算出した。
凹部深さ保持率(%)=〔加熱後の凹部の深さ/加熱前の凹部の深さ〕×100
(Evaluation of synthetic resin skin material: maintainability of uneven pattern)
In the obtained synthetic resin skin material 10, the surface roughness of the fluororesin-containing layer 16 on which the drawn pattern was formed was measured with a surface roughness meter (manufactured by Tokyo Seimitsu, Surfcom 130A).
Then, it heats until the surface of the fluororesin content layer 16 in the synthetic resin skin material 10 reaches 130 ° C., and the surface roughness of the surface of the fluororesin content layer 16 after the heating is the same as that of the synthetic resin skin material 10 before heating. The measurement was performed under the same conditions, and the surface roughness before and after heating was compared to calculate the recess depth retention by the following formula.
Recess depth retention ratio (%) = [depth of recess after heating / depth of recess before heating] × 100

その結果、加熱後の凹部深さ保持率は90%程度であり、絞模様の凹凸の形状が加熱後も維持されており、加熱後の外観も良好であった。加熱後の凹部深さの保持率を表1に示した。
なお、合成樹脂表皮材の加熱後の凹凸模様の維持性評価において、凹部深さ保持率が70%以上である場合には、加熱成形用の成形体用として実用に供しうるレベルであり、凹部深さ保持率が70%未満の場合には、実用上問題のあるレベルであり、なかでも、凹部深さ保持率が50%未満のものは、加熱成形する成形体表面に適用する合成樹脂表皮材としては不適なレベルである。
As a result, the concave depth retention after heating was about 90%, the shape of the irregularities of the drawn pattern was maintained after heating, and the appearance after heating was also good. Table 1 shows the retention ratio of the recess depth after heating.
In the evaluation of the sustainability of the uneven pattern after heating of the synthetic resin skin material, when the recess depth retention is 70% or more, it is at a level that can be practically used as a molded body for thermoforming. When the depth retention ratio is less than 70%, there is a practically problematic level. Among them, when the depth retention ratio is less than 50%, the synthetic resin skin applied to the surface of the molded body to be heat-molded It is an unsuitable level as a material.

なお、加熱成形した後の、成形体26表面における合成樹脂表皮材10においても、凹部深さ保持率が70%以上であれば、例えば、加熱を伴う成形体の形成に使用しても実用上問題のないレベルであり、70%未満であると実用上問題のあるレベルであると判断される。
