Bonded-type knitted net and bale net

Abstract

The present disclosure discloses a bonded-type knitted net and a bale net, belonging to the technical field of net knitting. In the bonded-type knitted net according to the present disclosure, warp yarns are arranged in parallel in a warp direction, weft yarns are distributed in a zigzag shape between every two adjacent warp yarns, and junction points between the warp yarns and the weft yarns are connected by bonding. Since there are no knots in the warp yarns, a strength loss caused by knotting in the warp yarns during knitting is eliminated, thus improving a strength. A stretch rate of the warp yarns in the knitted net is 30% to 80%, which maintains a high tensile strength on a basis of certain stretchability. In addition, a knitting width can be controlled according to a need and an efficiency is higher.
