Breathable textile printing and dyeing process and circulation system for same

Abstract

The invention discloses a breathable textile printing and dyeing process and a circulation system for same. The process includes: sealing the circulation space; through external force, generating pressure difference between the two sides of the breathable textile, wherein one side is under positive pressure whereas the other side is under negative pressure; in the direction vertical to the breathable textile, enabling a dye, or a dye-air mixture, to move, in a penetrating manner, from the positive pressure side to the negative pressure side at certain speed, so that when the dye-air mixture penetrates through the textile, the dye is adsorbed by the textile whereas air permeates the textile, thus achieving color fastness and the printing and dyeing of the textile. Because the dye moves in the direction vertical, or approximately vertical, to the textile at the certain speed and there is a pressure difference between the two sides of the breathable textile, the dye is free of diffusion,or may diffuse but is limited in an acceptable range, on the textile; thereby solving the problem of color bleeding during the printing and dyeing process.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a breathable textile printing and dyeing process and a circulation system thereof. Background technique [0002] Printing and dyeing is the general term for pretreatment, dyeing, printing, finishing, washing, etc. In recent years, environmental protection, energy saving and emission reduction have become a trend in my country's industrial development. As a polluting printing and dyeing industry, it is also facing a series of national policy restrictions. . [0003] my country's printing and dyeing industry occupies an important position in the national economy, but its pollution also restricts its development. In recent years, the state has listed the technological transformation of the printing and dyeing industry as the focus of the development of the textile industry, and has also given policy support in terms of technological development and scientific and...
