Ceramicizable size composition for continuous mineral filaments, filaments coated with composition and sizing process and heat treatment using the composition

摘要

A size compsn. which can be converted to a ceramic contains: (a) 5.5-20 wt.% of a water-sol. salt of Cr, Zr, Ti or Al; (b) 0.2-15% of a bonding agent; (c) 0.15-3% of a silane which confers good resistance to abrasion and tension to the continuous, dry, mineral thread; (d) 0.6-17% of a lubricant; and (e) water as the balance.
