Why should ceramic fiber cloth be sintered?

Ceramic fiber is short and brittle, and it is difficult to spin into yarn. Therefore, it is traditional to incorporate a certain proportion of organic fiber glue and then spun it into yarn. However, organic fiber is combustible and will burn or slowly carbonize in high temperature environment. Tobacco, therefore, to do a sintering process, that is, to heat the ceramic fiber products in the furnace for a certain period of time, so that the organic fibers are carbonized, so that the content of organic fibers in the ceramic fiber products is very small, and no smoke is emitted during use. Or only a very small amount of smoke will emerge.
