| 摘要 |
The invention relates to a papermaker's or industrial fabric, such as a dryer fabric for the dryer section of a paper machine, onto which a polymeric resin material is applied onto preselected locations on the backside of a base substrate using a piezojet array which deposits the polymeric resin material in droplets having an average diameter of 10-100 microns to build up discrete, discontinuous deposits of the polymeric resin material having a height of at least 0.5 mm at the preselected locations. The preselected locations may be the knuckles formed by the interweaving of the yarns making up the base substrate. The purpose of the deposits is to separate the backside of the dryer fabric from a surface, such as that of a dryer cylinder or turning roll, to enable air trapped between the dryer fabric and the surface to escape in lengthwise and crosswise directions parallel to the surface, instead of being forced through the fabric, possibly causing "drop off". The polymeric resin material is set by means appropriate to its composition, and, optionally, and, if necessary, may be abraded to provide the deposits with a uniform height above the surface plane of the base substrate. |
