8451400000The TY-JL631 is a high temperature overflow jet fabric dyeing machine designed for batch bleaching, dyeing, washing and scouring of polyester, polyester-cotton blended fabric, linen-cotton blended fabric and other compatible woven fabrics. It adopts a down-running long tube fabric path to support stable rope fabric circulation and repeated liquor-fabric exchange during wet processing.
This model is suitable for fabric weight from 60–800 GSM. The fabric speed can reach up to 600 m/min, the liquor ratio is 1:6–8, the working pressure is ≤0.44 MPa, and the maximum working temperature is 140℃.
This machine is recommended for dyehouses processing lightweight to medium-weight woven fabrics that require high temperature bleaching, dyeing, washing or scouring in batch production. For a wider overview of fabric dyeing machine options, please review our fabric dyeing machine category page.

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.
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.
| 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. |
