NONWOVEN CARBONIC MATERIAL Russian patent published in 1997 - IPC

Abstract RU 2100500 C1

FIELD: heat-insulating and filtering materials. SUBSTANCE: nonwoven carbonic material is produced by carbonization of viscose filaments connected by needlepunching. Material is made from continuous filaments oriented in longitudinal and transverse directions. These filaments fix vertical staggered filaments. Combustion loss coefficient of material is 64-87% by weight. EFFECT: increased efficiency, simplified structure of material and wider operational capabilities. 3 dwg, 1 tbl
