CERAMIC MATERIALS FOR THREAD GUIDES FOR TEXTILE MACHINERY

The choice of ceramics for textile machinery was a secondary problem in the past. Nowadays ever-faster production speeds, synthetic fibres and wearing technical yarns have led to ever-higher demands on thread guides.
In fact a mechanically perfect textile machine can undergo a drastic reduction in performance due to thread guides made from unsuitable ceramics. “Snow” formation on thread guides and high friction values lead to a reduction in process economic efficiency.
It is thus important to choose the right ceramic material on the basis of:
– yarn type;
– yarn count;
– number of fibres in the yarn;
– yarn speed.
The choice of materials should also depend on different applications of the thread guide itself.

REQUIREMENTS FOR THREAD GUIDES

Some of the most important properties a thread guide has to meet are:
– wear resistance;
– corrosion resistance;
– fracture strength;
– surface structure (not to damage the yarn).
