An atmosphere printing and dyeing device for cloth

Abstract

The invention discloses an atmospheric printing and dyeing device for cloth, relating to the technical field of printing and dyeing devices, comprising an outer cylinder and an inner cylinder, a vortex tube is arranged between the outer cylinder and the inner cylinder, and the vortex tube includes an air inlet pipe and a hot gas output end and the cold air output end; an outer cavity is provided on the outer inner wall of the outer cylinder, one side of the outer cavity communicates with the cold air output end, and the other side of the outer cavity communicates with the cold air exhaust pipe; A circle of inner cavity is provided on the outer inner wall of the inner cylinder, one side of the inner cavity communicates with the hot gas output end, and the other side of the inner cavity communicates with the hot gas exhaust pipe. In the present invention, by setting the vortex tube, when the atmosphere is sprayed, the hot air will preheat the cloth through the heat conduction of the inner cylinder, so that when the dye touches the cloth, the surface tension of the dye will be reduced and the dye will penetrate deep into the cloth; then it will run to the outer cylinder When the outer surface of the cloth is cooled, the surface tension of the dye at the undried part is reduced at the same time, so that the printing and dyeing are more uniform.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing devices, in particular to an atmospheric printing and dyeing device for cloth. Background technique [0002] At present, natural cellulose fibers such as cotton and hemp and regenerated cellulose fibers have various methods of applying reactive dyes. Wet steaming achieves the purpose of dyeing and color fixing, but it consumes steam energy due to the existence of a drying process. At the same time, the supersaturated steam generated by the wet steam causes waste of dyes and cannot penetrate deep into the fabric, so it is urgently needed to change. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and propose an atmosphere printing and dyeing device for cloth. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] It includes an outer cylinder and an inner cylinder....
