Problems solved by technology

In this method, thermal infiltration is carried out on the primary dyed textile chemical fiber, and the hot air flow is used to pass through the front side of the primary dyed textile chemical fiber, so that the ink on the surface can use the directional hot air during the high temperature color fixing process to complete the migration, penetration and color fixing at the same time. It solves the problems of penetration, drying and color fixation, shortens the technological process, saves dyes and energy, and reduces pollution, especially suitable for digital printing and dyeing of blankets and carpets

Abstract

The invention discloses a chemical fiber textile disperse printing and dyeing method which comprises the following steps: 1, preparing dye to obtain ink; 2, carrying out digital printing on the textile chemical fibers by using the ink to obtain primarily dyed textile chemical fibers; 3, carrying out heat penetration on the primarily dyed textile chemical fiber to obtain a printed and dyed textile chemical fiber; 4, performing post-treatment on the printing and dyeing textile chemical fibers to finish disperse printing and dyeing of the textile chemical fibers. According to the method, hot penetration is carried out on the primarily-dyed textile chemical fibers, hot penetration parameters are controlled, hot air flow penetrates through the front faces of the primarily-dyed textile chemical fibers, ink can be fully gasified and is brought into the primarily-dyed textile chemical fibers along with the hot air flow, migration penetration and color fixation are completed at the same time through directional hot air, and the problems of penetration, drying and color fixation are solved at a time; the process flow is shortened, dye and energy are saved, the dyeing effect is guaranteed, the production efficiency is improved, pollution is reduced, and the method is particularly suitable for digital printing and dyeing of blankets and carpets.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a textile chemical fiber dispersion printing and dyeing method. Background technique [0002] At present, heavy chemical fiber textiles such as blankets are mainly printed by traditional rotary screen printing and flat screen printing. The main disadvantage is that water pollution is serious. Digital printing is an emerging water-free environmental protection printing technology. It has achieved rapid growth in ordinary clothing fabrics and is gradually replacing traditional printing. However, the digital printing technology of heavy chemical fiber textiles such as blankets is still in the exploratory stage. At present, the digital printing method of heavy chemical fiber textiles such as blankets is mainly by increasing the amount of printing ink, adding penetrants and various auxiliaries at the same time, and combining the method of pressure penetr...
