Technical Ceramics For The Textile Industry
Products from technical ceramics are widely used in textile
industry, due to their advantages:
- long service life due to high wear resistance and corrosion
resistance;
- stable yarn quality;
- ability to work at different speeds (which is successfully used,
for example, in the production of microfilaments);
- universal cleaning options: acids, alkaline solutions, firing at
high temperatures or cleaning in an ultrasonic bath.
