2. According to the production process of the combined glass fiber cloth according to claim 1, it is characterized in that: the combined glass fiber
The production process of Webb includes the following steps:
(1) Manufacture of gray cloth: pass several glass fiber raw yarns through one-time combing and warping process, and then use the pulping machine to adjust the warp beam
(2) Paralleling: mix the warp yarn and weft yarn obtained in step (1), dip into the size tank to soak in the size, divide the wet sizing yarn after the size tank into the heat drying area, and dry the surface of the yarn with hot air to form a film;
(3) Thermal cleaning: Burn the organic matter such as slurry on the glass fiber cloth from 8% to 0.5 ~ 1.6%.
3. The production process of combined glass fiber cloth according to claim 1, characterized in that: in the step (2), the electric heating method is used to pretreat the cloth at a speed of 50m/min; 385±10℃, holding time is 18h
