A glass fiber having a low crystallization temperature, a low crystallization rate and an ultra-high content of aluminum; the glass fiber has a nominal diameter within a range of 5 micrometer to 13 micrometer, and the variation of the diameter of the glass fiber is within a range of ±15% of the nominal diameter. The glass fiber comprises 21-25 wt.% or 25.1-39 wt.% of aluminum oxide, 0.001-8.7 wt.% of sodium oxide and 7-14 wt.% of magnesium oxide, and comprises silicon oxide with a weight percentage 2.61-4.8 times greater than that of calcium oxide, and calcium oxide with a weight percentage 1-1.8 times greater than that of magnesium oxide. |
