Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a double-sided adhesive tape for adhering a rubbing cloth which can prevent the development of the floatation of the double-sided adhesive tape on an interface between the double-sided adhesive tape and a rubbing roller, and to provide a roller-winding rubbing sheet having the double-sided adhesive tape and one or more rubbing cloths integrated therein, which is made to fit with a long rubbing roller and reduce orientation nonuniformity and orientation defects.SOLUTION: The double-sided adhesive tape for adhering a rubbing cloth includes an adhesive layer I to be adhered to a roller on one side of a substrate film and an adhesive layer II, to which the rubbing cloth is adhered, on the other side. The double-sided adhesive tape for adhering a rubbing cloth uses, as a substrate film, the film having a stress of ≤20 N/15 mm measured 1 minute after the stoppage of elongation by 10%, and having a tensile stress of ≤3,000 MPa on 1% stretching. |
