Appl. No.:

12/752364

Assignee:

DELSTAR TECHNOLOGIES, INC. - Middletown DE

International Classification:

B01D 29/07
B29C 47/00

B32B 37/12

US Classification:

210490, 2641761, 15624411

Abstract:

A pleated filter structure includes a pleated filtering substrate and a pleated, polymer, mesh reinforcing sheet or netting for assisting in maintaining the pleated configuration of the filtering substrate. The pleated, polymer, mesh reinforcing sheet or netting includes a mechanically degraded polyalkylene terephthalate as the primary polymer therein. A method of making the pleated filter structure includes the steps of obtaining commercial articles having been made from a high crystallinity, flexible polyalkylene terephthalate; and mechanically degrading said articles to decrease the crystallinity and increase the stiffness of the polyalkylene terephthalate and extruding the mechanically degraded articles into an extruded structure stiffer and more amorphous than the polyalkylene terephthalate in the commercial articles.
