Knit fabric dyeing apparatus
By combining the pre-drying cylinder and the turbulence generator, the problem of unstable tension in knitted fabrics caused by excessively rapid heating in the drying cylinder was solved, achieving a drying effect with steady heating and stable tension, thus improving the quality of the knitted fabrics.

AI Technical Summary
Technical Problem
Existing drum dryers heat up knitted fabrics too quickly, causing unstable fabric tension, making them prone to deformation or damage, and affecting fabric quality.
Method used
The system employs a combination of a pre-drying cylinder and multiple drying cylinders. The pre-drying cylinder gradually raises the temperature before drying. Combined with a turbulence generator and siphon system, it prevents condensation from forming a water film inside the drying cylinder, ensuring steady temperature rise and stable tension of the knitted fabric.
Benefits of technology
It achieves steady heating and drying of knitted fabrics, maintains the stability of the conveying tension of the knitted fabrics, avoids deformation or damage, and improves the quality of the fabrics.

Abstract
This invention discloses a knitted fabric dyeing apparatus, comprising a fabric feeding frame, a scouring tank, a washing tank, a dyeing tank, and a drying drum unit connected in sequence. The drying drum unit includes a column, multiple drying drums, a steam inlet system, and a drainage system. The steam inlet system introduces high-temperature steam into the drying drums, and the drainage system discharges condensate from the drying drums. The drying drum unit includes several pre-drying drums located in front of the multiple drying drums. The knitted fabric is heated sequentially through the pre-drying drums from front to back before being dried by the drying drums. Each pre-drying drum includes an outer drum and an inner drum, forming a jacketed cavity between them. The jacketed cavities of the front and rear pre-drying drums are connected sequentially by pipelines. The jacketed cavity of the rearmost pre-drying drum is connected to the drainage system, and the condensate is discharged sequentially through the pre-drying drums from back to front. This invention provides a knitted fabric dyeing apparatus that steadily heats and dries knitted fabric, facilitating the maintenance of stable conveying tension.
