Description
A thermoset organic fiber produced from a phenolic novolac resin. The precursor resin is melt-spun in a solution of formaldehyde and hydrochloric acid. The reaction occurs and fibers are formed and cured. Novoloid fibers were initially developed in the 1960s. Commercial fiber production and development was done by the Gunei Chemical Industry Co. based in Japan.
