Abstract: A window treatment assembly that results in a plurality of horizontal folds when raised, the assembly having a decorative panel member, a liner panel member attached to the decorative panel member, a plurality of loop guide members positioned in horizontal rows on the front side of the liner panel member, horizontal slat members received by the loop guide members, a plurality of vertically oriented, substantially stiff, lifting band members passing freely between the slat members and the liner panel member, the band members being attached at or adjacent the lowermost row of the loop guide members, such that when the band members are retracted in the vertical direction, the decorative panel member and liner panel member are raised.

Abstract: Woven, knitted or otherwise manufactured decorative hanging fabric panels of synthetic or synthetic blended base yarns, the panels having integrated stiffened areas at one or more edges or in chosen internal areas made by interspersing in these areas stiffener yarns incorporating a composite mixture of low melt temperature filaments and common polymer filaments similar or identical to the base yarns. The stiffener yarns are designed to melt or plasticize at the temperature typically encountered in the tentering process for such fabrics. The stiffener yarns rigidify after cooling and bond with the base yarns to provide a controllable stiffness for the panel.
