FIELD: textile fabrics. ^ SUBSTANCE: new filtering fabric is made of main and filling thread from polyvinyl chloride yarn has surface density of 480 g/m2, density of threads per 10 cm by warp 100, by woof - 90, at that air permeability of fabric makes 110 dm3/m2 s. In particular, produced fabric may be additionally exposed to thermal treatment. Compared to available fabrics it has considerably lower shrinkage, is stable in process of thermal treatment (begins shrinking at 100C). ^ EFFECT: fabric may be used for cleaning of aggressive mediums of various nature, fabric parametres provide for good extent of cleaning, fabric is wear resistant, convenient in process of operation, in particular in vacuum-filters. ^ 3 cl, 2 ex |
