Tube difference refers to the color variation between different tubes of fabric during dyeing in the same vat. The causes of tube difference are multifaceted.

The direct causes are analyzed as follows:

(1) Varying quantities of distribution per tube.

In air-jet dyeing, the exchange of dye solution with the fabric is completed within the nozzle system, with the frequency of exchange correlating to the cycle of fabric circulation.

Regarding, while the cyclic period of the fabric is determined by the fabric speed and length, the fabric speed is controlled by the air volume and the speed of the cloth roller, generally speaking,

The speed of fabric feeding across different tubes on the same machine is generally consistent. Therefore, if there is a significant difference in the length of fabric between the tubes, it will result in uneven fabric transport across the tubes.

Significant differences in the circulation cycles, meaning that during the dyeing time, the exchange次数 between the tubes of fabric and the dye solution will be more considerable.

Large differences can cause tube color discrepancies.

(2) Differences in fabric speed.

In air-jet dyeing, the exchange times between the dye solution and the fabric are determined by the dye solution circulation frequency and the fabric speed, while in the dyeing process within the same vat,

The dye circulation frequency per tube is identical, therefore, in cases where the fabric length per tube is relatively consistent, any significant difference in fabric speed...

Large differences in the number of times the fabric and dye fluid exchange can cause tube differences.

(3) Blockage of the dye spray nozzle.

Serious clog in the dye spray nozzle can lead to the inability to continue dyeing, which is absolutely unacceptable: while minor clogs, though...

The issue does not affect the continuation of dyeing, but may cause discrepancies in dye tubes. Because, under normal circumstances, the orifice size and liquid volume of each nozzle...

The sprays are generally the same, but if there's a blockage, there may be variations in the spray volume. The differences in spray volume among individual nozzles can be quite significant.

Color tube discrepancies may occur. The cause of blockage is due to thread ends or too much long fluff and other debris entering the nozzle and not being able to...

Washed away by the dye solution.

(4) Leakage in the airflow nozzle.

Inside the nozzle system, the air flow nozzle is mounted on the nozzle seat. After installation, the air flow nozzle fabric inlet side and the gas-liquid two-phase

There should be good sealing between mixing rooms. If the sealing is not tight, it will affect the atomization effect of the dye solution, and the dye solution may leak.

Leakage on the intake side of the air jet nozzle; if the leakage is severe, it means that the amount of dye solution involved in the exchange with the fabric within the nozzle system is significant.

Reduction due to significant variations in the amount of dye solution exchanged with the fabric caused by this type of leakage in the air flow nozzles of each tube.
