Description

[Detailed description of the invention]

[Industrial Application Field] This invention uses one natural fiber and one synthetic fiber! ! ! ! The present invention also relates to a liquid jet dyeing machine that dyes a fabric such as a woven or knitted fabric, which is a blend thereof, by circulating a liquid such as a dyeing solution together. [Prior art] As a conventional liquid jet dyeing machine, for example, the
As in No. 81, both ends of the cloth are sewn together to make it endless, and this cloth is circulated together with the liquid in the dyeing machine body, and is held and retained in the retention section of the dyeing machine body, and is gradually heated to scouring, dyeing, and Some were washed with water. [Problems to be Solved by the Invention] However, in general, when cloth is impregnated with a liquid, the temperature of the liquid or, for example, an acid, changes as the treatment elapses. Changes in the state of liquids containing alkalis, detergents, etc. change the physical properties of the fabric, especially the stiffness. For this reason, even if the initial operating conditions of the jet dyeing machine, such as the type of fabric, moving speed of the fabric, type of liquid, circulation speed of the liquid, and flow rate of the retention section, are set optimally, the state of the liquid changes. As a result, the physical properties of the cloth deviate from the optimum values and become unsuitable, causing problems such as tangles of the cloth in the reel and retention sections, resulting in poor cloth circulation and scouring. There was a drawback that the dyeing and water washing processes could not be carried out smoothly. In particular, this phenomenon is caused by the bath ratio (liquid volume/cloth volume)
The smaller the value, the more noticeable it became. Conventionally, operators have been able to prevent problems such as cloth entanglement by sequentially adjusting the opening degree of the valve that removes the circulating liquid from the retention area, but this is a cumbersome process and is difficult to adjust. The drawback was that there were individual differences. Therefore, an object of the present invention is to provide a liquid jet dyeing machine that can operate stably without individual differences, without the need for operators to adjust the valve in the retention section to prevent troubles such as cloth entanglement. That's true.
