properties papermaking felts require

Papermaking felts require the following properties 

1.Dewatering ability.(drainability), remove as much water as possible out of wet paper web.
2.Transferability of wet paper web, transfer wet paper web safely to the next position by adhering the wet paper to the felt.
3.Runnability, avoid such undesirable conditions as snaking, deviation, vibration and wrinkling.
4.Wear resistance and hair shdding resistance,avoid wear in short running periods and keep shed fibers to a minimum.
5.Compaction resistance,avoid choking by increasing density and deposition of contaminating    substances and maintain resiliency  and elasticity in the early running stages.
6.Papaer surface smootheness, avoid any felt or roll markings.
7.Break-in, reach the desirable operating speed in the shortest time.
8.Uniformity, achieve a uniform evenness in felts.
9.Simple installation onto the paper machines requiring the least number of people and in the shortest time to finish it.
