FIELD: textile. ^ SUBSTANCE: invention is related to production of filtering materials, that can be used when cleaning hot process gases and industrial air at excess temperature (up to 300). Filtering cloth is weaved at loom by herringbone weaving pattern of the main and filling threads. Surface density of filtering cloth is from 250 to 350 g/m2, threads density in 10 cm section is from 310 to 330 in base and from 180 to 200 in weft . Additionally, air permeability of cloth is from 40 to 200 dm3/m2 s. ^ EFFECT: increased temperature of operation while preserving or improving cleaning quality and rate, no shrinkage at thermal treatment. ^ 2 cl, 2 ex |
