PAPTEX RY Round Yarn Dryer Fabric

Round Yarn Dryer Fabric

PAPTEX RY round yarn dryer fabric is a polyester dryer-section fabric for paper machines. Its construction is selected around sheet support, air handling, contamination conditions and the dryer-group layout.

Our engineers review the existing fabric, paper grade and operating conditions before confirming a suitable construction.

- Q: When should I choose Round Yarn over Flat Yarn dryer fabric? / A: Round yarn gives a mark-free fabric surface, ideal for quality-critical grades such as tissue, fine paper and specialty papers where sheet surface matters most. Flat yarn is preferred for higher-speed machines needing maximum surface smoothness and heat transfer. Our engineers can recommend the right construction from your machine profile. - Q: Which seam type is recommended for Round Yarn dryer fabric? / A: Pin seam is the standard choice. Loop seam offers the easiest on-machine installation. The best option depends on your dryer section configuration and maintenance preference. - Q: Can Round Yarn dryer fabric be used on packaging grades? / A: Yes. It is suitable for tissue, packaging and specialty paper. For heavy board, kraft and corrugated where maximum tensile strength is required, we typically recommend Spiral dryer fabric instead. - Q: What sheet surface quality can I expect? / A: The round monofilament profile eliminates flat-yarn marking, giving a clean, mark-free sheet surface. Uniform round-yarn geometry also prevents hot spots and uneven drying.
