Glass yarn, which is free of boron oxide, comprises silicon dioxide (55-65 wt.%), aluminum oxide (9-16 wt.%), calcium oxide (15-26 wt.%), magnesium oxide (1-5 wt.%), mixture of barium oxide and strontium oxide (0.5-5 wt.%), mixture of sodium oxide, potassium oxide and lithium oxide (0-2 wt.%), titanium dioxide (0-1 wt.%), zinc oxide (0-2 wt.%) and zirconium oxide (0-2 wt.%). Independent claims are included for: (1) a composite of glass yarn and organic and/or inorganic material comprising the glass yarn; and (2) a preparation of the glass yarn comprising stretching in the form of continuous filament sheet of molten glass nettings flowing through several openings disposed at the base of one or more nozzle, and assembling the filaments in yarn collected on a moving support. |
