Glass fiber yarn connecting method

The invention discloses a glass fiber yarn connecting method. The glass fiber yarn connecting method comprises the following steps including the step 1 of taking head ends and tail ends of adjacent two yarn clusters, manually winding yarns by a plurality of rings on positions where the tail-end yarns are pulled out and distances of 15-25 cm from the yarn clusters is generated, and putting the yarns into inner rings of the tail-end yarn clusters; the step 2 of determining first knot positions on positions, which are about 5-15 cm from the yarn clusters, of the tail-end yarns, and putting the tail-end yarns and the head-end yarns at one side in parallel; the step 3 of dividing the head-end yarns into an strand A and an strand B, wherein the strand B is split in a half-and-half manner to forma strand C and a strand D, the C-strand yarns and the D-strand yarns separately pass through from the two sides of the tail-end yarns and are re-combined into one strand, and the yarns which are combined into one strand rota
