Abstract
Нетканый фильтрующий материал, включающий каркасное полотно в виде нетканого материала и волокнистые слои по одну или обе стороны от каркасного слоя из синтетических штапельных волокон, отличающийся тем, что каркасное нетканое полотно и волокнистые слои выполнены из смеси полиэфирных волокон в соотношении мас.% 50:50, при этом каркасное полотно представляет собой матрицу с размером пор в пределах 25÷60 мкм, а отношение размера пор нетканого фильтрующего материала и матрицы составляет от 1:2 до 1:5. Non-woven filter material comprising a frame web in the form of a non-woven material and fibrous layers on one or both sides of the frame layer of synthetic staple fibers, characterized in that the frame non-woven cloth and fibrous layers are made of a mixture of polyester fibers in a ratio of wt.% 50:50 wherein the frame web is a matrix with a pore size in the range of 25 ÷ 60 μm, and the pore size ratio of the nonwoven filter material and the matrix is from 1: 2 to 1: 5.
