Staubfilterbeutel für einen Staubsauger |
摘要 |
A disposable vacuum filter bag is constructed of layers which include a high-air-permeability first layer (10) positioned upstream in the direction of air flow of a second filtration layer (11). The second filtration layer (11) can be a meltblown fleece, a wet-laid filter paper, a dry-laid filter paper or a spunbond nonwoven. The first layer (10) can be made of a high-bulk meltblown nonwoven, dry-laid or wet-laid high-dust-capacity paper, spunblown modular nonwoven or microdenier spunbond nonwoven. A filter and a method for removing particles entrained in a gas where the filter has the same type of constructional features as the disposable vacuum filter bag are also disclosed. |
