Abstract: The present invention relates to fabrics having a special structure, methods of producing the fabrics, and various articles including clothes comprising such fabric. Specifically, the fabrics of the invention are characterized in that many narrow strips forming an overlapping structure are combined together so that each overlap between adjacent narrow strips provides an opening in the width direction of the strips. The methods of producing the fabrics are characterized in that narrow strips are put one on top of another while slightly shifting the positions thereof to form an overlapping structure, followed by combining the adjacent narrow strips while maintaining the overlap. Where used as material for clothes, for instance, these fabrics produce clothes that prevent the skin of the wearer from being exposed directly to sunlight and rain and have unique features including a high fashionability and a high air permeability ensuring a good ventilation.

Abstract: A varied thickness laminate or panel (92, 128) is fabricated by polar winding incomplete lamina or plies (54, 146, 148) on a mandrel (10, 110, 130) at selected angles. The plies (54) are wound at crossing angles, first one layer (60) at one angle and then a second layer (64) at a second angle. At the most remote crossing point from a wide starting end (32), a V (66) is formed between the crossing plies (60, 64) and in the space (62) formed by the V (66), no plies extend on the mandrel side (30).

The first V (66) starts a taper from wide starting end (32) to narrow other end (34). Successive plies are wound around the mandrel from the polar ends (48, 50, 134), each successive set forming a V so as to thicken the windings in steps formed by the V's.

Abstract: A process is provided for the continuous production of nonwoven webs in the form of a flexible tube from thermoplastic fibers, spinning the fibers continuously from a melt onto a rotating mandrel and continuously withdrawing the web from the mandrel in the form of a flattened tube. Density of the web is controlled by controlling the distance between the rotating mandrel and the orifices of the spinning die through which the molten polymeric material is spun, and by controlling the diameter of the fibers. If the spinning of the fibers is continuous, the flattened tubular web can be formed in a continuous length. Control of the spinning rate in relation to the diameter of the mandrel and the rate of withdrawal of the tubular web from the mandrel controls the thickness of the web. The web drawn off the mandrel can be used as a tube, or slit lengthwise and opened out, or collapsed onto itself, for use as a double layer sheet.
