Features
 
It is Hokushin Corporation's PU-DISC for twisting that is one of the precision functional parts of a textile machine which can ideally handle such filaments. The PU-DISC has excellent durability and is best suited to high-speed operation. It also satisfies our sensory requirements of touch and sight.

Advantage of "HOKUSHIN's PU - DISC"

Beginning with a rubber molecular design, Hokushin Corporation has invested its resources in studying rubber physical properties and adaptability to oils. Several kinds of rubber materials are always available to customers so that a wide range of their quality requirements can be met.

 •Low CV factor
 •Less filament breaks
 •Excellent Durability

PU DISC have the following adavantages over Ceramic Discs

High-quality yarns free of damage can be produced since crimp contraction is performed by means of rubber resilience when the rubber disc surface and filaments are brought into frictional contact. When conventional hard discs made of materials such as ceramic are used, filaments are caught on their uneven surfaces when they are mechanically crimp contracted. This unavoidably damages filaments, decreases filament strength, or yields objectionable fluffs. On the other hand, the PU-DISC helps produce filaments which are better by far than those from the hard discs due to its resilient crimp contraction. It is also suitable for twisting fine and micro filaments.
