Basalt fiber yam for textile is kind of twisted yarn made through twistingand combining multiple basalt filaments, its monofilament diameter generallyranges from 5.5 μ m~9 μ m.Textile yarn can be divided into yarns for textilewith industrial technology and yarn, thread and rope for industrial usage.Weaving yarn mainly includes the bipyramid tube yarn and the bottle-typeyarn.
