Title: Cellular linear filaments with transverse partitions

Abstract: Cellular linear filaments are disclosed and include a substantially continuous, integral plastic hollow member having internal generally transverse partitions which divide the hollow member into cells. The wall of the hollow member can be continuous or can contain orifices, slits, windows and the like. The cells can be open or closed and uniformly or randomly spaced along the tubular member. The cells are defined by transverse partitions which can be integrally formed with the hollow member or they can be seals in the hollow member. Woven, non-woven and tufted materials including yarns made up in part or in total of the cellular linear element are also disclosed. The cellular linear element can be cut into discrete lengths to form pile-like elements which can be attached upright to a base to form a multi-element device.
