What is the line on the top of the filter bag?
The filter bags are divided into three types: the ribbon filter, stationary filter and twill filter.
Twill is good for wear-resisting and dust removal, but it is softer and less elastic than the satin weave, which is the most used in machine weaving
The plain tissue, which is difficult to clean up dust and easy to clog, is rarely used in the removal of dust
Among them, the satin weave is glossy, smooth, soft, flexible, breathable and easy to remove dust from cloth bags.
