Abstract

The invention discloses an inkjet printing and dyeing process. The process comprises the following steps: pouring a raw material reactive dye, resin and a dispersing material into water and stirring, then adding a binding material into the mixture, and stirring to obtain inkjet dye liquor; treating fabric by using an ammonium salt solution, and then carrying out drying treatment to obtain salt-treated fabric; adding acid-base adjusting fluid into the inkjet dye liquor so as to adjust the pH value of the dye liquor to be 10-11, then carrying out jet dyeing on the salt-treated fabric by using the inkjet dye liquor, and carrying out drying treatment; carrying out thermal curing treatment on the treated fabric, and then cooling the fabric to obtain the printed and dyed fabric. The inkjet printing and dyeing process provided by the invention is good in printing and dyeing effect, high in stability and low in dye fade rate.

Description

technical field [0001] The invention relates to the field of methods for dyeing with reactive dyes, in particular to an inkjet printing and dyeing process. Background technique [0002] The printing and dyeing process is known as a key link in the textile industry chain, carrying important functions such as creating added value and product differentiation. At present, my country's printing and dyeing process has problems such as relatively backward technology, serious pollution, and low added value. Due to its precision, controllability and high industrial level, inkjet printing and dyeing technology has developed extremely fast in recent years. For different types of fabrics, the dyes and processes used in printing and dyeing are also different. For reactive dyes, the active groups in the molecular structure can chemically react with the fibers of the fabric to form a covalent bond, which greatly improves the level of printing and dyeing, but there are also low affinity o...
