Nano-osmosis washing-free technology for polyester fabric

Abstract

The invention belongs to the technical field of printing and dyeing, and particularly discloses a nano-osmosis washing-free technology for polyester fabric. A base, a motor and a controller are included; a pressurizing box and a separating box are mounted on the upper surface of the base; a pressurizing cavity is formed in the pressurizing box; a separating cavity is formed in the separating box;the motor is mounted between the pressurizing box and the separating box; the motor is a bidirectional output motor; a power cavity is formed in the position, located below the pressurizing cavity, ofthe pressurizing box; a power cavity is formed in the position, located below the separating cavity, of the separating box; output shafts of the motor extend into the power cavities; and the parts, located inside the power cavities, of the output shafts of the motor are sleeved with first bevel gears. According to the technology, through gasification and compression of a carbon dioxide fluid andthrough osmosis of dissolved disperse dyes into fibers in the gasification process, on one hand, carbon dioxide is gasified quickly under the normal pressure without residues, meanwhile, the carbon dioxide is recycled continuously, and the cost of the printing procedure is saved effectively.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and in particular relates to a process for polyester fabric nano-penetration without washing. Background technique [0002] In the prior art, stencil printing and thermal sublimation transfer printing technologies are often used for printing polyester fabrics, in which stencils are used to directly print dyes on the fabrics. Due to the need for pretreatment of the fabrics, a large amount of dyes must be used after printing. On the one hand, the discharge of waste water exceeds the standard, which has a great impact on the environment. Thermal transfer printing technology needs to print disperse dyes on the transfer paper first, and then sublimate the dyes into the fabric through high temperature and high pressure. The process does not require water washing, but due to incomplete dye sublimation during transfer printing, it consumes a lot of heat transfer paper, and at the same time, h...
