Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a dyeing machine for dyeing by jetting a phase fluid.

[0002]

2. Description of the Related Art A conventional dyeing machine for performing dyeing by jetting a two-phase fluid includes a cloth circulation path and a nozzle provided in the cloth circulation path. The guide tube and the cloth storage tank are connected. The principle of the operation is to use the pressure of the dye solution ejected from the nozzle.
That is, the cloth to be dyed is put into the cloth circulation path, and a high-pressure dye solution ejected from a nozzle is jetted onto the cloth to perform the dyeing. Then, the cloth is returned to the nozzle position by passing through the cloth storage tank, and the next dyeing process proceeds.

[0003] Invented by the present inventor, in 1998
Publication No. 215063 “Gas-liquid type dyeing machine” published in January of the year has the above-mentioned structure.

[0004] However, such a structure causes the fabric to be dyed to be twisted or entangled in a rope shape.
In order to remedy this drawback, the present inventor has improved the cloth guide tube and the cloth storage tank, and has devised a dyeing machine having a nozzle capable of selecting the front and rear jetting directions of the dye solution. The inventor is the publication No. 337795 “Gas-liquid dyeing machine” published in Taiwan in July 1998.

However, in order to solve the above-mentioned drawbacks in the conventional dyeing machine, the nozzle must not only jet the dyeing liquid but also jet the dyeing liquid at a sufficiently high pressure to propel and circulate the cloth. . For this reason, the dye solution pump must have a particularly high output and requires a large amount of dye solution.

Further, since the fabric to be dyed is pushed out and moved in a state where the fabric to be dyed is stacked in the cloth storage tank, folds are easily generated, and such folds may cause defects in dyeing.

In view of this, the present inventors have devised a two-phase fluid dyeing machine. The inventor of the present invention is the publication No. 42775 “Gas-liquid dyeing machine” published in Taiwan in March 2001. The invention mixes and sprays a mist of dyeing liquid and air to dye the fabric and promote the fabric. Therefore, the dye solution pump does not need to have a particularly high output, and only a small amount of the dye solution needs to be used. In addition, the fabric to be dyed is provided with a linear nozzle, and the airflow is intermittently jetted for a predetermined time, so that the fabric to be dyed is continuously stacked in an N shape. Therefore, it is possible to solve the problem that the fabrics are stacked in the process of being dyed while circulating in the body as in the related art, and the folds are generated due to the pressure.

[0008] However, each of the two-phase fluid dyeing machines (ie, "gas-liquid type dyeing machines") in the above-mentioned prior arts has different dye liquors depending on different conditions such as the type of fabric or the thickness of the fabric. It is not possible to appropriately adjust the injection amount and the amount of gas. Therefore, the control of the dyeing form is inadequate and the dye may be wasted.In addition, if excess dye or impurities adhere to the dyed fabric, it is difficult to completely wash it, which may affect the quality of dyeing. May give. This also needs to be improved.

[0009]

SUMMARY OF THE INVENTION The present invention has been developed in view of the above disadvantages found in the prior art. That is, a two-phase fluid dye ejecting apparatus provided in the body of the dyeing machine, the type of the cloth to be dyed by independently adjusting the jetting amount of the dyeing liquid and the gas and the mixing ratio of the liquid and the gas. An object of the present invention is to provide a two-phase fluid dyeing machine that can easily adjust the amounts of a dyeing liquid and a gas according to the thickness.

Further, the present invention provides a two-phase fluid dyeing machine in which, even by using a soft material, a linear fold mark is not generated due to wrinkles or twists during dyeing by adjusting the jetting pressure. That is the task.

It is another object of the present invention to provide a two-phase fluid dyeing machine capable of washing dyed fabric and removing excess dye or impurities to improve dyeing quality.

Another object of the present invention is to provide a two-phase fluid dyeing machine in which the structure of the nozzle portion is simplified so that maintenance such as cleaning can be performed very easily.
