The blowable flexible innerduct contains an outer innerduct structure and an inner innerduct structure. The outer innerduct structure contains at least one outer longitudinal chamber formed from at least one textile. The inner innerduct structure contains at least one inner longitudinal chamber, where each inner longitudinal chamber is located within an outer innerduct textile chamber and the at least one inner longitudinal chamber contains an inflatable tube. The inflatable tube has a wall thickness of less than about 0.5 mm. The inner longitudinal chamber alone has an air permeability of less than about 1 cfm, outer longitudinal textile chamber alone has an air permeability of greater than about 100 cfm, and the outer and inner longitudinal textile chambers together have an air permeability of less than about 1 cfm.

Blowable flexible innerduct

A container is described having at least one sheet of paper folded and adhered to form a body defining an interior space. The body has an inner surface and an outer surface and contains at least one window portion in at least one of the sides. The window portion comprises a hole in the sheet of paper. The container further contains a textile material, where the textile material contains biodegradable yarns and an adhesive composition. The adhesive composition contains at least 50% by weight of a vinyl acetate ethylene co-polymer having a glass transition temperature of between about 10 and 30° C. The adhesive composition forms between about 20 to 60% by weight of the textile material. The textile material is adhered to the inner surface of the body at least in the window portion and completely overlaps the hole in the sheet of paper.

Container with scrim window

The process of forming a blowable flexible innerduct contains the steps of forming an inner innerduct structure comprising at least one inner longitudinal chamber, where the at least one inner longitudinal chamber comprises an inflatable tube and forming a textile. Concurrently forming an outer innerduct structure from the textile having at least one outer longitudinal chamber and inserting at least one inner longitudinal chamber into at least one of the outer longitudinal chambers. The inflatable tube has a wall thickness of less than about 0.5 mm. The inner longitudinal chamber alone has an air permeability of less than about 1 cfm, outer longitudinal textile chamber alone has an air permeability of greater than about 100 cfm, and the outer and inner longitudinal textile chambers together have an air permeability of less than about 1 cfm.
