PURPOSE: To obtain the subject product, capable of preventing normal surfaces, etc., from eroding, etc., useful for protecting the normal surfaces and greening and used for vegetation at a low cost by knitting or weaving tapelike weft yarns according to doup weaving and forming double parts in the resultant net using a specific method.
CONSTITUTION: The objective product 4 obtained by initially subjecting tapelike weft yarns 2 to doup weaving with many warp yarns 1 at 3-9 weft yarns/inch weft yarn interval for each suitable interval in the transverse direction to provide a single net, subsequently liberating half of the warp yarns 1 in the aforementioned single net from the weft yarns 2 for each suitable interval in the longitudinal direction and simultaneously beating the weft yarns 2 into the liberated warp yarns 1 at the same ratio as that of the weft yarn interval of single net weave parts 3 to carry out knitting or weaving. In using the resultant product as a vegetative net, fertilizer bags are contained in the resultant double parts.
