Loose type tension-free continuous zero-emission hot melting dyeing unit for knitting and weaving

The invention provides a loose type tension-free continuous zero-emission hot melting dyeing unit for knitting and weaving and belongs to the technical field of cloth dyeing. The dyeing unit comprisesan evenness padder, a first baking cabin, a second baking cabin, a third baking cabin and a fourth baking cabin and is characterized in that the first baking cabin, the second baking cabin, the thirdbaking cabin and the fourth baking cabin are sequentially distributed from left to right and are connected through mesh bags and air ducts. The dyeing unit has the advantages that equipment synchronous rotation is controlled through a PLC communication synchronous control program system, equipment stability is increased, and dyeing efficiency is increased at the same time; by a cloth retaining roller, cloth fixing guidance is achieved while cloth is prevented from deviation and shaking; cloth conveying is promoted by the multiple mesh bags; synchronous loose type conveying is performed by multiple mesh strips, fabric
