工艺参数对针刺过滤毡孔径及透气的影响
Effect of technological parameters on pore diameter and ventilation of needled filtrated felt
摘要
Abstract
In order to explore the effect of acupuncture density,different mixing ratio,hot roll-ing process on the pore size and the permeatility of needle punched filter,taking the polyester fiber,ES fiber as raw materials,mixing ratio 30:70,50:50,70:30,through nonwoven needle acupuncture process,the needle punched filter samples with five different needling den-sity are prepared.Then,ten samples with proportion 50:50 of polyester fiber and ES fiber are selected for hot rolling(hot rolling temperature is 170 ℃).A total of ten samples were prepared and tested.The results show that before and after hot rolling,with the needle density increas-ing,the average pore size has a polynomial decrease,the maximum pore size exponentially de-creases and the permeability has a polynomial decrease.Before hot rolling,with the increase of needling density,the permeability and the pore size decrease greatly.After hot rolling,with the increase of the density of acupuncture,the permeability and the pore size decrease slightly.In the same needle density,average pore size and maximum pore size decrease with the increase of the proportion of fine fiber.关键词
