Atmosphere printing and dyeing device for cloth

Abstract

The invention discloses an atmosphere printing and dyeing device for cloth, and relates to the technical field of printing and dyeing devices. The atmosphere printing and dyeing device for the cloth comprises an outer barrel and an inner barrel, wherein a vortex tube is arranged between the outer barrel and the inner barrel and comprises an air inlet pipe, a hot air outlet end and a cold air output end; a circle of outer cavity is formed in the inner wall of the outer side of the outer barrel; one side of the outer cavity communicates with the cold air output end; the other side of the outer cavity communicates with a cold air exhaust pipe; a circle of inner cavity is formed in the inner wall of the outer side of the inner barrel; one side of the inner cavity communicates with the hot airoutput end; and the other side of the inner cavity communicates with a hot gas exhaust pipe. By arrangement of the vortex tube and during atmosphere spraying, hot air preheats the cloth through heat conduction of the inner barrel, so that when dye is in contact with the cloth, the surface tension of the dye is reduced, and the dye penetrates into the deep part of the cloth; and when the cloth is conveyed to the outer surface of the outer barrel, the cloth is cooled, and meanwhile, the surface tension of the dye at the undried position is reduced, so that printing and dyeing are 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....
