    摘要: A surface for contacting a moving finish coated textile yarn at elevated yarn treatment temperatures in the presence of oxygen. The surface is characterized by irregular, rounded nodules which bears within its interstices finely-divided catalyst particles that will catalyze oxidation of finish deposits that form on the surface at the yarn treatment temperature. The time between periodic cleaning cycles is greatly lengthened with attendant savings in labor and loss of production.
