LOW TEMPERATURE PLASMA PROCESSING METHOD OF DIGITAL TEXTILE PRITING FABRIC USING NATURAL DYE INK

摘要

The present invention relates to a low-temperature plasma processing method of a digital textile printing fabric using natural dye ink, and a release roller 111 and a winding roller 113 provided on the front side of the pretreatment unit 120 and the rear side of the printing unit 130 The fabric mounting step (S10) in which the fabric is attached to the fabric to pass through each unit continuously while the fabric is unwound, and between the upper and lower electrodes 122 and 123 in the chamber of the pretreatment unit 120, among oxygen, argon, and nitrogen. A gas injection step (S20) of injecting a gas composed of one or a mixture thereof, a plasma generating step (S30) of generating a low-temperature plasma by applying a high-frequency power source 124 to the upper and lower electrodes 122 and 123, and the upper and lower portions Plasma reaction step (S40) of spraying low-temperature plasma onto the fabric surface with a treatment time of 5 to 30 cm/s while transferring the fabric between the electrodes 122 and 123, and the fabric discharged from the chamber of the pretreatment unit 120 is printed in a printing unit ( 130), and the printing step (S50) of printing with natural pigmented ink is included, and thus the absorption and dyeing properties of dye are improved and process efficiency is increased during digital textile printing using natural pigmented ink.
