Textile sheet filter

摘要

A sheet filter made up of a flat textile article carrying micrometric particles of a resistant and/or adsorptive additive, the textile article made up of fibers which upon heating become temporarily adhesive without fusing. Advantageously the textile article is a nonwoven fibrous fleece or a pile fabric; if a fleece, a second fleece can be placed over the additive particles so heating unites the fleeces as well as adhereing the particles.
