Environment-friendly energy-saving cloth printing and dyeing process

Abstract

The invention belongs to the technical field of textile printing and dyeing, and particularly relates to an environment-friendly energy-saving cloth printing and dyeing process. A boiling-off device used in the process comprises a pool body with an opening in the upper end; the position, close to the bottom, of the pool body is provided with a group of guide rollers, and one ends of the guide rollers are rotatably connected with the side walls of the pool body; the interior of the pool body between the adjacent guide rollers is fixedly connected with a sliding barrel, and the interior of the sliding barrel is in sliding connection with a sliding column; the top of the sliding column is fixedly connected with a rotating shaft, the rotating shaft is sleeved with a tensioning roller, and thetensioning roller is rotatably connected with the rotating shaft; a first hole formed in the rotating shaft in the axial direction communicates with a water pump through a pipeline and a valve; a second hole is reversely formed in the middle of the rotating shaft along the diameter of the cross section of the rotating shaft, and the second hole communicates with the first hole; and the position, corresponding to the second hole, of the tensioning roller is provided with an annular groove, and a group of spraying holes communicating with the annular groove are uniformly distributed in the outercircumference of the tensioning roller. A desizing agent is sprayed to grey cloth by the spraying holes, so that the desizing efficiency of the grey cloth is improved.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, in particular to an environmentally friendly and energy-saving cloth printing and dyeing process. Background technique [0002] Printing and dyeing is also called dyeing and finishing. It is a processing method, and it is also a general term for pretreatment, dyeing, printing, finishing, washing, etc.; the existing dyeing and finishing specialty has now been incorporated into the light chemical engineering specialty; the current development trend of the printing and dyeing industry at home and abroad is high efficiency, Energy saving and environmental protection, these three aspects complement each other and are indispensable. In order to develop productivity, improving production efficiency is the most direct means; and energy conservation has reached the stage where measures must be taken; while adopting energy conservation measures to develop productivity, environmental aw...

Problems solved by technology

[0007] In order to make up for the deficiencies of the prior art and to solve the problem of desizing the cloth during the textile printing and dyeing process in the exhaust dyeing process, the cloth will still have some floating hair and some fine particles, and if these fine particles are not Clean up, pollute the desizing agent with the cloth into the desizing tank, and increase the failure rate of the desizing device at the same time, the infiltration efficiency of the cloth and the desizing agent is low, it needs to consume a large amount of desizing agent, consumes raw materials and increases the risk of pollution Problem, a kind of environmental protection and energy-saving cloth printing and dyeing process that the present invention proposes
