PURPOSE:To provide a net insert having a uniform insert in its entirety and to prevent the meshes of the net insert from being clogged, by forming predetermined reinforced parts of the net insert with yearn having a tensile strength which is higher than general yarn forming the other part of the net insert. CONSTITUTION:A net insert 16 is composed of weft 26A in the vicinity of left and right edges of a developed movable section, and warp 26B in the vicinity of a coupling part in the coupling and fixing section for a base insert. Further, the weft 26A and the warp 26B have a tensile strength which is higher than that of general yarn which is used for knitting the remainder general section of the net insert. With this arrangement, the net insert has a uniform thickness in its entirety and the meshes of the net insert is prevented from being clogged. |
