用于工业除尘目的的纺织过滤套传统上是由编织和针毡结构制造的。由于针织织物在过滤过程中受到作用力时具有高延展性和各向异性，因此没有认真考虑将其用作过滤介质。本文介绍了几种新型单针织圆针织除尘器结构的开发和评价，特别介绍了它们在压降、压降稳定性、粉尘排放水平和过滤效率方面的性能。研究了这些织物的机械性能和过滤性能，并与类似的机织和针刺过滤织物进行了比较。实验证明，这些结构的物理和过滤特性与机织物和针毡织物相当，而且生产成本更低，而且这些过滤套可以在编织过程中生产到所需的形状和尺寸。
Textile filter sleeves for industrial dust-collection purposes are traditionally manufactured from woven and needlefelt constructions. Knitted fabrics have not been seriously considered for use as filter media because of their high extensibility and anisotropy when subjected to the forces that are involved during filtration.This paper is concerned with the development and evaluation of a number of novel single-jersey circular-knitted structures for dust-filtration applications, with particular reference to their performance with regard to the pressure drop, pressure-drop stabilisation, dust-emission level, and filtration efficiency. The mechanical and filtration properties or these single-jersey structures are studied and compared with those of similar woven and needlefelt filter fabrics. It is demonstrated that the physical as well as the filtration characteristics of these structures are comparable with those of woven and needlefelt fabrics, with added benefits of lower production costs and the fact that these filter sleeves can be produced to the required shape and dimensions during knitting.
