Abstract: A non-single crystalline semiconductor material includes coordinatively irregular structures characterized by distorted chemical bonding, reduced dimensionality and novel electronic properties. A process for forming the material permits variation of the size, concentration and spatial distribution of coordinatively irregular structures. The electronic properties of the material can be changed by controlling the characteristics of the coordinatively irregular structures.

Abstract: A three-dimensional highly elastic film/non-woven composite having a fluid and air impervious core layer and a first and second consolidated layer. The consolidated layers have unidirectional and non-unidirectional fibers. The composite is formed by laminating the air and fluid impermeable elastic core layer between the two layers of consolidated non-wovens. The resulting composite stretches only in the cross-machine direction due to the unidirectional properties of the consolidated non-woven material. The layers are then point bonded or welded together. Preferably the layers are welded by passing the composite between an ultrasonic horn and an ultrasonic bond roll having raised areas for effecting the weld points. A thin inelastic membrane is formed at each of the weld points. The welded composite may then be pre-stretched to rupture the membranes, thereby creating apertures, which makes the composite permeable.

The polymeric back layer is prepared from SBC (styrenic block copolymer) for the advantage of low specific gravity and preventing the drawback of PVC or the like that pollutes the environment when disposed off. The protective layer is prepared from PU series or modified SBC (styrenic block copolymer) series agent. When the fabric structure used to make a bag, the front surface of the fabric base sheet is disposed outside the bag and the surface of the protective layer is disposed inside the bag.

Alternatively, a central layer may be disposed between at least a portion of the first and second webs. The central layer may carry a substance to be exposed or the central layer may be a dissimilar material from the first and second webs.
