12 well within the broad scope of the invention suitable material for inner sleeve 12 includes but is not limited to open mesh scrim or screen thin single layer woven fabric joined spun bonded fibers films and the like which preferably have cross direction stability the material should have minimal machine direction or warp yarns suitable material could be a 0 005 inch pet which has good stretch resistance the machine direction yarns can preferably have a spacing of about 5 25 yarns per inch preferably 10 15 yarns per inch cross direction yarns can be in the typical amounts normally used for such structures further as an alternative and or enhancement to pin seaming inner sleeve 12 can be joined using an ultrasonic cutter or the like and the joint can be reinforced with a thin perforated film or iron on adhesive if desired another alternative for inner sleeve 12 would be to provide same through a preferably low cost extruded netting process for making the scrim once inner sleeve 12 is provided and formed into an endless loop machine direction yarns of outer sleeve 14 can be applied machine direction yarns 20 can as one non limiting example be a single mono or plied monofil yarn winding of yarn onto inner sleeve 12 can be done from a creel and reeds can be used to maintain spacing after winding of the yarns of outer sleeve 14 a batt material is attached to fabric 10 to lock inner sleeve 12 and machine direction yarns 20 of outer sleeve 14 together the batt can be needle punched and a low melt adhesive can be used as well the composite tube of inner.
