Jet Dyeing Machine and Working Principle | Jet Dyeing Process (Textile Dyeing Machine) @TextileTV

Summary

This video explains the technology behind the Jen Jess floating jet dyeing machines, which have been highly successful for decades. These machines are ideal for dyeing knit, woven, and nonwoven fabrics, especially those with high-quality requirements. The process involves several key components: a preparation tank for mixing dyes, a main pump for circulation, adjustable nozzles for even dye application, and transport systems for moving fabric through various stages. The fully automated system ensures efficiency and precision in dyeing while minimizing fabric tension.

Takeaways

• 😀 Jet dyeing machines have been highly successful for decades, providing a gentle process for fabric dyeing.
• 😀 These machines are suitable for a wide range of fabrics, including knit, woven, and nonwoven materials, especially those with high requirements.
• 😀 The preparation tank, which includes a dosing pump, is used for preparing dyes and chemicals to be introduced into the system.
• 😀 The main pump circulates the dyeing liquor, sending it through a filter, heat exchanger, and nozzle for the dyeing process.
• 😀 The nozzle sprays a water-based dye mixture evenly onto the fabric, allowing it to penetrate the fibers and move the fabric forward.
• 😀 After the nozzle, the fabric is transported to the back of the main tank chamber via a transport pipe.
• 😀 The fabric then crosses a compressing device that introduces incoming water and compresses the fabric to prepare it for the next stage.
• 😀 The fabric is opened in the flooded chamber through a 'swimming effect' and sent back to the nozzle by a winch.
• 😀 The winch's low height ensures minimal tension on the fabric during the movement, preventing damage.
• 😀 The dyeing process of spraying, compressing, and transporting the fabric is repeated continuously for consistent results.
• 😀 New developments in fully automated jet dyeing machines increase precision and efficiency in the dyeing process.

Q & A

What is the main advantage of Jen Jess floating machines?

The main advantage of Jen Jess floating machines is their extremely gentle process for goods, making them suitable for critical fabrics with high requirements. They offer universal applicability for knit, woven, and nonwoven fabrics.

What is the purpose of the preparation tank in the machine?

The preparation tank, including the dosing pump, is used for preparing the dyes and chemicals required for the dyeing process. These are then introduced into the system.

What does the main pump do in the dyeing machine?

The main pump is responsible for circulating the liquor through the system. It draws the liquor from the machine and ensures it passes through the necessary components like the filter and heat exchanger before reaching the nozzle.

How does the nozzle contribute to the dyeing process?

The nozzle sprays the water-based mixture evenly onto the fabric, which penetrates the fibers and moves the fabric forward, enabling the dyeing process to take place.

What happens to the goods after they pass through the nozzle?

After passing through the nozzle, the goods are transported to the back of the main tank chamber through a transport pipe below the machine.

What role does the compressing device play in the process?

The compressing device helps the fabric relax by compressing it, preparing it for the opening in the flooded chamber. It also facilitates the flow of incoming water into the chamber.

How does the swimming effect contribute to the process?

The swimming effect opens the goods, helping to transport them back to the nozzle. This ensures the continuous movement and treatment of the fabric during the dyeing process.

What is the function of the winch in the machine?

The winch transports the goods back to the nozzle. It operates with an extremely low height, causing minimal tension on the fabric, ensuring a delicate handling of the materials.

How is the dyeing process repeated in the machine?

The dyeing process is repeated constantly, with the goods continuously moving between the nozzle, transport pipe, compressing device, and winch, ensuring thorough dye application and fabric treatment.

What new feature has been developed in the Jen Jess floating machines?

The new feature in the Jen Jess floating machines is the fully automatic operation, which enhances efficiency and consistency in the dyeing process.
