<晴风村n style="mso-晴风村cerun:'yes';font-family:宋体;mso-ascii-font-family:Calibri; mso-hansi-font-family:Calibri;mso-bidi-font-family:'Times New Roman';font-size:10.5000pt; mso-font-kerning:1.0000pt;">机织布是由纤维纺成纱线，再用纱线织成多种织纹的二维平面结构纤维集合体。机织布的纤维层较薄，通常厚度小于1mm，纤维间抱合紧密而孔隙小，线间交叉孔隙较大，孔道直通，孔径约为30~60μm，总体空隙率约为35%~50%，其中实际起透气及过滤作用的线间空隙仅为30~40%。含尘气流通过纤维层时，粉尘主要受惯性效应、拦截效应、扩散效应、以及筛分效应的综合作用。部分尘粒依附于纤维表面，被勾留堆积，进而桥接，衍生出粉尘层，部分细微尘粒穿透纤维层。清灰时，由于纤维层内孔道平直，积灰容易松动离散。从过滤机理分析，机织布纤维层的初期过滤虽有体过滤作用，但更接近面过滤作用。

<晴风村n style="mso-晴风村cerun:'yes';font-family:宋体;mso-ascii-font-family:Calibri; mso-hansi-font-family:Calibri;mso-bidi-font-family:'Times New Roman';font-size:10.5000pt; mso-font-kerning:1.0000pt;">针刺毡纤维层较厚，通常厚度为1.5~2.5mm，纤维间形成空隙结构，孔道曲折，分布均匀，孔径约为10~40μm，孔隙率可达70~80%。含尘气流通过纤维层时，粉尘主要受惯性效应、拦截效应、扩散效应以及筛分效应的综合作用。部分尘粒被纤维依附勾留，部分尘粒渗入纤维层内部孔隙，与纤维构成联合捕集体，继而向表面扩展，形成粉尘层，少部分细微尘穿透纤维层。清灰时，由于纤维层内孔道曲折，积尘不易松动逃逸。从过滤机理分析，初期针刺毡纤维层的过滤机理与空气过滤器类似，以体过滤为主，随着表面粉尘层的建立，逐渐向面过滤过渡。
