Fiberglass yarn is made from 9-13um fiberglass filament which is then gathered and twisted into one finished yarn. In accordance with the production and processing methods, glass fiber yarn can be divided into the first twist fiberglass yarn and twist glass fiber yarn.
According to sizing agent type, Fiberglass yarn can be divided into starch fiberglass yarn, silanes glass fiber yarn, and paraffin glass fiber yarn.
According to application, it can be divided into electronic grade fiberglass yarn and industrial grade fiberglass yarn.
Fiberglass yarn is suitable for electronic base cloth, curtain line, casing, fiberglass mesh, filter, and other products manufacturing.
