Hokushin PU DISC
High-Performance Polyurethane Discs for Industrial Applications

Introduction :

High qualityFriction Discs, made of either rubber or ceramics, are assembled together with other parts for a texturing unit as shown in the photo, and work to produce synthetic filaments in a micron thin size from fibres via the stretching-twisting processes in the texturing machine. In the case of our PU-Disc, "Resilience Twisting" process is applied by friction force, induced during running the fibre on the surface of the discs rotating at a high speed, while it is mechanically done with rough surface of the ceramics discs.

Thus, the product texturized with the PU-Discs has an advantageous quality such as :

• Less damage on the filament after the processing
• Better texturing ability
• Filament strength is kept to the original after processing
• Generation of fluff staff is prevented during processing

To help to achieve plumy feeling fabrics, our PU-Disc is made of "Polyurethane Rubber" which was specifically developed with these excellent characteristics :

• Keep the friction force stable through the service life
• Wear resistance for high speed operation
• High temperature resistance
• Oil resistance

Additionally, the structural superiority of our PU-Disc is well accepted by our customers for a better operation due to the uniformity in quality regardless production lots :

• Excellently polished surface without micron size flaw
• High accurate dimensions
• Ridged in high speed operation
