The specific embodiment
Utilize glass fibre to prepare the method for filtrating smoke dust material; Glass continuous filament yarn (GF) 6 and 5 two kinds of multifilament of polytetrafluoroethylene fibre (PTFE) are processed the compound buiky yarn of PTFE/GF through the pressure-air winding-up in bulking machine; See also Fig. 1, the compound buiky yarn of PTFE/GF is three high bulk yarns: high bulking degree, the high bulking uniformity, high strength retention rate; Folding quality is good, textile performance is more superior;
The multiply alkali-free glass fibre of preferred filament diameter 5.5～6.2 μ m of glass continuous filament yarn, polytetrafluoroethylene fibre is preferably the multifilament of 400～500D, and glass continuous filament yarn and polytetrafluoroethylene fibre all can pass through prior art production.
When bulking machine was expanded, the proportioning of glass continuous filament yarn and polytetrafluoroethylene fibre was 70～85: 15～30 (weight ratios).
The compound buiky yarn of PTFE/GF is processed into the base cloth of twill latitude two layer tissue structures through weaving loom.The grammes per square metre of base cloth is 350～900g/m
