| Abstract: | In the present study, a novel needle with a modified cross-sectional shape that can reduce the damage of woven substrates has been developed. The results show that as compared to the needles with triangular cross-section, the use of needles withmodified cross-section can provide higher tensile strength in both machine direction and cross direction for woven substrates and fabric filters, regardless of punching density. Meanwhile, fabric filters prepared by new needles also show almost same clean gas concentrations with the fabric filters made by traditional needles. |
