METHOD FOR THE MANUFACTURING OF A LOW SHRINKAGE FLEDXIBLE SHEET |
摘要 |
The invention relates to a method for the manufacturing of a low shrinkage flexible sheet, said sheet comprising a fabric containing polyolefin fibers, said method comprising the steps of: a) depositing a molten plastomer layer on at least one surface of the woven fabric to form a sheet having a thickness approximately equal with the sum of the thicknesses of said molten plastomer layer and of said fabric; and b) impregnating said fabric with at least part of the molten plastomer layer by drawing the sheet into a gap between two calendaring rollers at a temperature of between the melting temperature of the plastomer and the melting temperature as determined by DSC of the polyolefin fibers, said gap having a width smaller than the thickness of the sheet; wherein the width of the gap is chosen to apply an impregnation pressure on the sheet of at least 20 bars. |
