FIELD: production of woven and non- woven materials, structural basal plastics and composites for filtration of liquids and gases; application of coats; reinforcing material for concrete. SUBSTANCE: method includes melting the rock and delivery of melt to production zone to dies. Production is performed at height of melt above dies not exceeding 60 mm; melt is taken from level of melt above intake hole at ratio of height of level of melt above intake hole to total height of melt above dies ranging from 0.15 to 065. Ratio of total area of intake holes to total area of cross-sections of dies ranges from 0.25 to 0.5. EFFECT: simplified procedure; reduced power requirements at retained quality parameters of fiber. 2 dwg, 3 tbl |
