Why Choose a Down-Running Long Tube Structure?

In woven fabric dyeing, stable fabric running is important for reducing the risk of rope disorder, fabric blockage, knotting and uneven treatment. The TY-JL631 uses a down-running long tube path to guide the fabric after the nozzle and return it to the fabric storage chamber in continuous rope circulation.

The long tube structure provides an extended fabric running route, while the storage chamber allows the fabric to accumulate in rope form during operation. This arrangement is suitable for woven fabrics that require controlled tension and stable movement during bleaching, dyeing, washing or scouring.

For knitted, elastic, velvet or other special fabrics, another fabric dyeing machine structure may be more suitable. You can also check our fabric dyeing machine selection guide to compare woven fabric, knitted fabric and overflow dyeing machine options.

How the Overflow Jet Circulation Works

Before dyeing, the fabric is usually sewn end to end to form a continuous fabric rope. During operation, the fabric moves through the nozzle, guide tube and fabric storage chamber repeatedly. The nozzle provides the main driving force and creates active liquor-fabric exchange.

At the same time, the dye liquor circulates through the main circulation system. The liquor is delivered back to the nozzle area, where it exchanges with the fabric during each circulation cycle. This combined fabric circulation and dye liquor circulation supports uniform bleaching, dyeing, washing and scouring.

By adjusting the process according to fabric type, GSM, loading quantity and treatment requirement, the machine can help maintain suitable fabric tension, liquor flow and running condition.

Main Structural Components

Component Function
Dyeing vessel / fabric storage chamber Stores the fabric during operation and allows the fabric rope to accumulate inside the machine.
Lifting roller Assists fabric circulation and helps guide the fabric rope during running.
Jet nozzle Provides driving force for fabric movement and is a key area for liquor-fabric exchange.
Guide tube Connects the nozzle and vessel, giving the fabric an extended running path after the nozzle.
Main circulation pump Supports dye liquor circulation and provides liquor flow for the nozzle area.
Heat exchanger Used for heating, temperature holding and cooling during the process.

Practical Advantages for Dyehouses

For Woven Blended Fabrics

Suitable for dyehouses processing polyester, polyester-cotton, linen-cotton and other compatible woven fabrics within the confirmed GSM range.

One Machine for Multiple Wet Processes

The machine can be used for bleaching, dyeing, washing and scouring according to the selected process, helping factories handle different wet treatment steps.

Stable Rope Fabric Running

The down-running long tube path helps guide the fabric through a defined route, which is useful when processing woven fabrics that require stable circulation.

Selection Based on Real Fabric

Tube quantity and configuration should be matched with fabric width, GSM, loading quantity, steam condition and production target before quotation.

Before Model Selection

To recommend a suitable TY-JL631 fabric dyeing machine configuration, please confirm the following information before quotation:

  • Fabric material, such as polyester, polyester-cotton blend or linen-cotton blend
  • Fabric width and GSM
  • Required process, such as bleaching, dyeing, washing or scouring
  • Target batch capacity per cycle
  • Required working temperature
  • Factory steam condition, water condition and voltage
  • Destination port or delivery term for freight calculation
