Abstract: A net structure for use of both sports and leisure is mainly made up of a net body having a plurality of net yarns integrally woven into a large meshwork of coarse and three-dimensional cords wherein within each net hole of the large meshwork is interwoven a small net layer to form a net-within-net fabric structure. The large meshwork is increased in frictional resistance for barring objects caught at the net body therein; the small net layer can gather the outstretched large meshwork thereof, preventing the large meshwork from getting loose easily and permitting the net body thereof to be flexibly expanded within a certain range. The small net layer also forms a protective layer to stop objects like balls from breaking through thereof. Moreover, the net body can be integrally woven by net yarns of two or more than two different colors with the large meshwork in contrast or matching with the small net layer in different colors to verify and increase the beauty of the net body in display.
