FLEXIBLE COAT ABRASIVE SHEET OF FINE GRAIN, POLYESTER CLOTH WOVEN TO PRODUCE SUCH SHEET, AND PROCESS FOR CALENDERING THE SAID CLOTH HOT

摘要

Calendering a polyester fabric at a pressure of 110 to 360 kg per linear cm and at a temperature of 100 to 195 DEG C yields a smooth surface on which a fine-grained abrasive can be deposited, in order to produce fine-grained flexible coated abrasive articles for polishing applications. The invention also relates to the polyester fabric thus calendered and to the coated abrasive articles comprising this polyester fabric as a support element.
