Viscose fiber, also known as viscose silk, is a kind of man-made fiber. Viscose fiber is the main variety of man-made fibers and the second largest chemical fiber variety in China. The preparation of viscose includes dipping, pressing, crushing, aging, yellowing, dissolving, aging, filtration, defoaming, bunching, cutting and post-processing, etc. The cutting knife is used in the cutting process. The formed fibers contain acid and sulfur. Therefore, during the cutting process, the requirements for the material of the cutting knife are relatively high. In the cutting process, not only high efficiency is required, but double-length fibers cannot appear. It is possible to increase the number of tons cut and reduce production costs. 

Therefore, a material with acid corrosion resistance, strength, toughness and strong wear resistance is required as a cutting knife. Stellite/Stellite alloy is a cobalt-based superalloy, and unlike many other materials that sacrifice toughness for wear and corrosion resistance, the Stellite family of alloys combines both, with excellent wear resistance, thermal Hardness, corrosion resistance and excellent mechanical properties, so it is widely used in the cutting of viscose.

Through a large number of research and production practices, combined with the use environment of the cutting blade, our company invented TP80, it is a special stellite alloy. TP80 Series cutting blade are produced by the powder metallurgy process to refine and grain to improve the mechanical properties, further enhancing the service life.

Our company has the invention patent for this product and process. At present, most companies currently producing viscose short fibers in the international market and domestic market have established good cooperative relations with us.

If you have any questions or any need for Stellite alloys, SYTOP is happy to solve your problems.
