Abstract

The invention discloses a treating agent for digital printing and dying as well as a preparation method and an application method of the treating agent. A coupling cationic graft modification agent is prepared by using a cationic auxiliary agent, a cationic etherifying agent, a humectants, an organic solvent and water, and is sprayed on the back of pretreated fabric; the fabric is dried and subjected to digital printing, and is soaked in a coupled reaction agent prepared from a reactant, organic acid and water, a color developing agent reaction solution prepared from a color developing agent and water, and a dye-fixing reaction solution prepared from a dye-fixing agent and water respectively for 30 seconds to react for being dyed; finally, watering is carried out. The treating agent as well as the preparation method and the application method of the treating agent have the advantages that the digital dyeing treatment can be completed quickly at normal temperature, high temperature is not required, and various fibers can be dyed by using direct dyes, acid dyes and reactive dyes.

Description

technical field [0001] The invention relates to a dyeing treatment agent, a preparation method and an application thereof, in particular to a digital printing dyeing treatment agent, a preparation method and an application method. Background technique [0002] In recent years, with the competition of dyeing and finishing industry, digital textile and the rapid development of technology, the industry's requirements for dyeing color quality have also been continuously improved, requiring the use of environmentally friendly methods with high dyeing rate, energy saving, fast dyeing speed, and dyeing The color is bright. The dyeing of existing digital textiles is divided into two kinds of process routes: hot and cold transfer printing process and digital textile dyeing and finishing process. Digital textile dyeing and finishing processes include reactive dye digital printing process and acid dye digital printing process, among which: [0003] 1. Reactive dye digital printing p...
