Problems solved by technology

Most of the dyeing methods adopt the two-bath two-step dyeing method, that is, the disperse dyes and cationic dyes are dyed in two baths. This process is less difficult to process, but the process is long and the energy consumption is high.
There is also a one-bath two-step dyeing method, that is, dyeing with disperse dyes first, and then dyeing with cationic dyes after cooling down. The process is shorter than the two-bath two-step method, but the processing is difficult and prone to color defects

Abstract

The invention discloses a one-bath and one-step-method dyeing method of a dacron cation composite shell fabric. The spun dacron cation composite shell fabric is sequentially treated by steps of pre-treating, washing by hot water, washing by cold water, dyeing, washing by water, reducing and washing, and drying. The one-bath and one-step-method dyeing method of the dacron cation composite shell fabric disclosed by the invention has the advantage the one-bath and one-step-method dyeing method is adopted, and a disperse dye and a cation dye are used for dyeing in the same bath; a process flow is the shortest and the energy consumption is the lowest; and the suitable disperse dye and cation dye are selected to be combined, so that the leveling property of the shell fabric is improved.

Description

technical field [0001] The invention relates to a textile dyeing method, in particular to a polyester cationic composite fabric dyeing method. Background technique [0002] Polyester cationic composite fabrics can develop distinct imitation yarn-dyed effects through dyeing processing, and can also achieve two-color or multi-color hazy multi-level tones. The polyester fibers are dyed with disperse dyes, and the cationic modified polyester fibers are dyed with cationic dyes. Most of the dyeing methods adopt the two-bath two-step dyeing method, that is, the disperse dyes and cationic dyes are dyed in two baths. This process is less difficult to process, but the process is long and the energy consumption is high. There is also a one-bath two-step dyeing method, that is, dyeing with disperse dyes first, and then dyeing with cationic dyes after cooling down. The technological process is shorter than the two-bath two-step method, but the processing is difficult and prone to color ...
