    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.
