HD DF241 High temperature High pressure

Cone Yarn Dyeing Machine

The machine is suitable for boiling, bleaching, dyeing, and washing  cotton, wool, synthesize fiber, cone yarn, hank yarn or zipper tape.

DF241E series is a new generation high efficient energy saving cone yarn dyeing machine, which adopts 180° plate type reversing arrangement, external high efficient shell-and-tube heat exchanger and new type centrifugal pump’s integral connection method. Compared with the regular models, it has advantages of more compact structure, lower bath ratio, less energy consumption and lower production cost.

The elaborate designed air cushion type and fully flooded type cone yarn dyeing machines are two the choices among DF241E series for users for different dyeing technology. DF241E series high temperature high pressure dyeing machine is suitable for bleaching and dyeing various kinds of natural and chemical fiber and their blends such as pure cotton, polyester cotton, polyester, wool polyester, nylon, acrylic, ramie cotton, wool, etc. With different kinds of creel it can bleach and dye different yarns such as cheese, skein, zipper, beam yarn, loose fiber, etc.

Advantages

•  Integral type heat exchanger, centrifugal pump and 180° plate type reversing arrangement. No external circulation piping. Saving 20% space.

•  High efficient energy saving external new heat exchanger.

•  The main pump’s motor is controlled by frequency inverter and the flow volume can be steplessly adjusted to obtain the dyeing synchronization required by technological curves.

•  Unique, stable and reliable reversing arrangement. When the liquid flow is changing its direction the main pump does not stop and this increases the dye liquor’s circulation times to raise dyeing quality.

•  Advanced computer, controller can display temperature curve, procedure and output, etc. Fully automatic controlled dyes dosing, water feeding, draining, heating, temperature keeping, cooling and rinsing, etc. Which can meet the dyeing technology requirement and they can be connected to the central control system.

•  Low bath ratio(1:5~1:7) saves dyes, auxiliary agent, steam and water. Much less waste discharging.
