Method and apparatus for digital textile printing

Abstract

A method for digitally controlled application and fixation of dyestuff to a textile on a processing line is provided. The method comprises the steps of: determining one or more parameters of a textile (10); determining, by a processor, at least one dose setting for an array of flow channel dispensers of the processing line, wherein determining the at least one dose setting is based on the one or more parameters (12); dispensing, by the array of flow channel dispensers, dyestuff onto the textile according to the at least one dose setting (12); and delivering energy to the substrate to fix the dyestuff in the textile.

Description

technical field [0001] The present invention relates to a method and apparatus for dispensing dyestuffs onto a textile substrate, and more particularly to a process design for textile dyeing on a production line using an array of independently digitally controlled flow channel distributors and a fixation energy source, which Design eliminates flush waste and reduces energy costs. Background technique [0002] Precise coating or dyeing is achieved by digital control of the orifice of the flow channel distributor, so that the 2D and 3D distribution of the industrial dye fluid can be controlled within a few percent of the target value. This principle of precise application of dye fluid is applicable to many industrial materials. The technology utilizes liquid application control combined with ambient airflow control to achieve a uniform three-dimensional distribution of liquid dye within the textile material. [0003] Precise fixation is achieved by digitally controlling ener...

Problems solved by technology

All conventional methods generally leave the textile material with an excess of dye that must be removed through repeated high temperature washing, resulting in large volumes of polluted wastewater
