FILTERING FIBER

摘要

1. A filtering fiber made by a combined twill weave of synthetic threads, main of them are combined, and weft are textural, characterized in that the twill weave is a combination of serge with a thrust 4/1+1/1+4/2+1/2, wherein the water permeability of fiber is 1,9-2,3 dm<3>/m<2>, and the air permeability is 150-1803 dm<3>/m<2>. 2. The fiber according to claim 1, characterized in that the main and weft threads are polyamide. 3. The fiber according to claim 2, characterized in that the linear density of main threads is 93,5 tex, and weft threads is 130 tex. 4. The fiber according to claim 2, characterized in that elementary threads comprising weft threads are profiled. 5. The fiber according to claim 2, characterized in that the coefficient of twist for main threads is 18,0, and weft threads is 16,0.
