For the adhesive tape roll after storage under the above conditions, the tester grabbed the tip of the adhesive tape with his hand and pulled it out in the tangential direction at a speed of about 1000 mm / min, and evaluated the unwinding property based on the response and peeling at this time. . The results are also shown in Table 1. In Table 1, ○ in the column showing rewinding property indicates that the rewinding property is good, and △ indicates that the rewinding property is slightly poor (slightly heavier or slightly lighter than ideal response), X represents that the rewinding property is poor (too heavy or too light). All of the adhesive tape rolls according to Examples 1 to 7 had an unwinding force in the range of 0.5 to 2 N / 150 mm and a good unwinding property immediately after production.
図5,6に示す概略形状を有する粘着テープロール用治具50の回転部52に、上記条件で保存した後の粘着テープロール10を取り付けた。そして、温度23℃、相対湿度50%の測定環境下にて、試験者が治具50のグリップ54を軽く持ち、治具50のシャフトと床面56とのなす角度θが55°となるようにして、725mm/秒の速度で平滑な板張り面(ここでは板張りの床)56上を転がした。このときグリップ54にかかる力(回転抵抗値)を、デジタルフォースゲージで測定した。その結果を、粘着剤層の幅150mm当たりの値に換算して表1に示した。また、このとき試験者が得た手応えにより粘着テープロールの使用感を評価し、その結果を表1に併せて示した。表1中、使用感を示す欄の○は使用感が良好であることを、△は使用感がやや不良である(理想的な手応えよりもやや重い、またはやや軽い)ことを、×は使用感が不良である(重すぎる、または軽すぎる)ことを表している。なお、例1~7に係る粘着テープロールは、いずれも、作製直後において、回転抵抗値が6~12N/150mmの範囲にあり、且つ良好な使用感を示した。 [Rotation resistance and feel]
