Friction disc is the key twisting element of friction type false twisting machine; different surface materials deliver different friction coefficient and wear resistance for high-speed filament twisting.
Polyurethane friction disc has moderate friction coefficient and low noise during operation, widely applied for PET multi-filament DTY production under medium speed.
Ceramic friction disc features high hardness and long service life, fit for high-speed production and processing of high-tenacity industrial filament.
Polyurethane disc surface will gradually form fiber transfer layer after long time running. This layer affects twist transmission efficiency and needs periodic cleaning.
Lanxiang False Twisting Machine allows mixed configuration of ceramic and PU discs, adjusting friction combination according to target twist requirement and filament type.
Friction disc surface roughness needs regular check. Surface polishing or grooving failure reduces friction and leads to insufficient twist on finished yarn.
Disc stacking gap directly impacts filament contact path. Too small gap causes yarn pinching and breakage; too large gap reduces effective friction contact area.
When replacing friction discs, avoid mixing new and heavily worn discs on same twisting unit. Inconsistent disc condition creates twist difference across spindles.
Storage of spare friction discs should avoid high temperature. High heat accelerates aging and hardening of polyurethane material before installation.
A common misconception: higher friction coefficient always creates better twisting effect. Excessive friction scratches filament surface and lowers yarn breaking strength.
