Today everybody in Textile field is talking about technical textiles. Meeting end product specification is a big challenge especially for industrial goods. Numbers of new textile fibres have been invented by researches for meeting customers demand. Basalt fibre, a fibre extracted from basalt rock can be used effectively in various fields owing to its superior properties. Not only do they boast good mechanical and chemical resistance, but also exhibit excellent thermal, electric and acoustic insulation properties. Due to all these favorable properties, Basalt fibre can be used in several applications in technical textile. In this paper formation, properties and applications of basalt fibre have been discussed.
Basalt fibre or Basalt rock fibre is manufactured from extremely fine fibres of the basalt, which composed of Pyroxene, Minerals plagioclase and Olivine. Basalt rock is abundantly found everywhere all around the world. Basalt is a generic name for solidified lava which poured out the volcanoes. It is 1/3 of earth crust. Basaltic rocks are melted approximately in the range 1500-1700°C. When this melt is quickly quenched, it solidifies to glass like nearly amorphous solid. So cooling leads to more or less complete crystallization, to an assembly of minerals. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of planet.
