The invention discloses an industrial non-directional curtain belt and a manufacturing method of the industrial non-directional curtain belt, which relate to a light conveyor belt for a rapid roller shutter door and a manufacturing method of the light conveyor belt for a rapid roller shutter door. The industrial non-directional curtain belt is mainly applied to industrial rapid roller shutter doors and can be applied to ultra-wide roller shutter doors. The industrial non-directional curtain belt uses a polyester fabric as a basic fabric, and a structure of a PVC (polyvinyl chloride) adhesive layer adhered between two basic fabrics is adopted. The basic fabric is a non-lateral stable polyester fabric which does not contain monofilaments and whose fabric count is 4030. Ultralow shrinkage polyester multifilament with the warp-wise and weft-wise finenesses which are both 1000D is twisted at the speed of 60 turns per meter. The industrial non-directional curtain belt provided by the invention provides the ultra-wide curtain belt for the industry of rapid roller shutter doors and the curtain belt can be cut vertically according to the width of the roller shutter doors so as to meet the requirement of width. In addition, the industrial non-directional curtain belt provided by the invention can be used bidirectionally to avoid the width splicing step of the original roller shutter door, thereby lowering the business cost and reducing the yield of unaccepted products.
