Description

Technical Field

[0001] This invention relates to the field of dyeing machine technology, and in particular to a composite dyeing machine. Background Technology

[0002] In the textile printing and dyeing industry, dyeing machines are the core equipment for fabric coloring. Overflow dyeing machines use overflowing dye liquor to drive the fabric to circulate within the guide tube, featuring low fabric tension, good hand feel, and wide applicability. They have long been the primary equipment for dyeing knitted and fine fabrics. With increasingly stringent energy conservation and emission reduction requirements, airflow dyeing machines have emerged. These machines utilize high-speed airflow instead of water as the medium for fabric movement, circulating the fabric through airflow nozzles. They offer significant advantages such as low liquor ratio, low water consumption, rapid heating, and low wastewater discharge, and are widely used in dyeing chemical fiber fabrics, microfiber fabrics, and high-density fabrics.

[0003] Most existing dyeing machines are difficult to flexibly select overflow or airflow dyeing methods according to fabric type and process requirements, resulting in poor equipment versatility.
