Textile printing and dyeing printing drying system and method
ActiveCN114407537AExtended drying pathAvoid wrinklesHeating/cooling textile fabricsTypewritersTextile printerSteam condensation
The invention relates to the technical field of textile drying, in particular to a textile printing and dyeing printing drying system and method. The three drying mechanisms arranged in the inverted triangle shape are adopted, so that the transverse space proportion is reduced, meanwhile, the cloth drying path is increased, the cloth is rolled and flattened through cooperation of the abutting rollers and the anti-abrasion rollers while the cloth is dried by the drying mechanisms, and the cloth drying efficiency is improved. And an electric heating plate is installed at the right end of the V-shaped base, the electric heating plate irons the cloth to prevent the cloth from wrinkling, meanwhile, a steam condensation mechanism is adopted for cooling and discharging steam generated in the cloth drying process, and therefore the cloth drying effect is improved. And the phenomenon that the cloth drying speed is low due to the fact that the water content of air in the drying box is high is prevented, and therefore the cloth drying efficiency is improved.
