Spiral single-yarn piezoelectric spray dyeing device

Abstract

The invention relates to the technical field of yarn dyeing, in particular to a spiral single-yarn piezoelectric spray dyeing device. The device comprises a rotary yarn pay-off module, a piezoelectric spray dyeing module and a rotary yarn take-up module which are connected in sequence. The rotary yarn pay-off module and the rotary yarn take-up module synchronously rotate in the same direction, yarn between the rotary yarn pay-off module and the rotary yarn take-up module rotates around the center axis of yarn in the piezoelectric spray dyeing module, the rotating yarn is subjected to spray dyeing of a plurality of piezoelectric spray heads in the piezoelectric spray dyeing module, the rotary yarn pay-off module is used for supplying yarn to be spray-dyed to the piezoelectric spray dyeing module, and the rotary yarn take-up module is used for the yarn which is spray-dyed by the piezoelectric spray dyeing module and dried is spooled into rolls. The device has the advantages that the rotationally advancing yarn is coated through the piezoelectric spray heads arranged above the yarn, the yarn can be evenly spray-dyed after the spray dyeing tracks of the spray heads are overlapped, the device is more even than single-side spray dyeing of traditional spray dyeing, more dyeing liquid is saved compared with traditional dip dyeing, and different sections of one piece of yarn can be dyed with different colors.

Description

technical field [0001] The invention relates to the technical field of yarn dyeing, in particular to a helical single-yarn piezoelectric jet dyeing device. Background technique [0002] Most of the existing single yarn dyeing devices adopt two methods of dip dyeing and jet dyeing. Equipment using the dip dyeing method, including patents ZL201310550132.7, ZL201220183093.2 and ZL 201310551500.X, will face problems such as insufficient use of dye liquor and waste, and a yarn can only be dyed in one color. Existing equipment using jet dyeing, including ZL201420667869.7 and ZL200410028019.3, all use one-side jetting, which is likely to cause uneven dyeing of yarns. At the same time, the nozzles of the existing jet dyeing equipment are prone to fugitive dust during high-speed operation, and because the control of the jet dye dosage is not precise enough, it is easy to cause dye particles to float in the air, thereby polluting the air and affecting the quality of the yarn.
