Composition containing sizing agent for inorganic fibers and method for producing inorganic fibers

Abstract

Disclosed is an inorganic fiber sizing agent-containing composition that contains an inorganic fiber sizing agent and water. The inorganic fiber sizing agent contains a polyamide compound composed of a constituent unit A and a constituent unit B, and a nitrogen-containing compound. The molar ratio of the constituent unit A to the constituent unit B is constituent unit A/constituent unit B=49.0/51.0 to 43.0/57.0. The constituent unit A includes a constituent unit formed from a tetracarboxylic acid or a derivative thereof. The constituent unit B includes a constituent unit formed from a diamine or a derivative thereof. The nitrogen-containing compound is at least one selected from the group consisting of ammonia, a tertiary amine compound, and an aprotic nitrogen-containing heterocyclic compound. The mass ratio of the polyamide compound content to the nitrogen-containing compound content in the inorganic fiber sizing agent-containing composition is polyamide compound/nitrogen-containing compound=54/46 to 31/69.
