However, the above conventional examples (1), (2), and (3) are all subjected to in-liquid processing by loading an object to be processed and providing a rotating inner cylinder in the dyeing liquid of the outer cylinder.
[0008]
In addition, in the configuration of (1), the effect that the dyeing solution penetrates into the inside of the yarn is recognized by being struck by the partition plate against the cylindrical knitted fabric in which the workpiece is contracted, but it can be processed softly. It is not suitable for a preferable object to be processed.
In the configuration of (2), the inner cylinder is immersed in the liquid of the outer cylinder and the interior of the cylinder is divided into a plurality of compartments so that the dyeing liquid of the outer cylinder is obtained through the mesh structure of the inner cylinder. Not suitable for low bath ratio treatment.
[0009]
Further, in the configuration of (3), there is a feature in the presence of a heat exchanger that supplies steam and cooling water from the upper part of the outer tank.
[0010]
Further, as in the case of (4), when the processing liquid is supplied by the pump, there are problems such as the cost required for the installation of the pump and the contamination of the circulation piping accompanying the pump.
[0011]
The purpose of the present invention is to eliminate the above-mentioned difficulties of the conventional example, and even when the liquid level supplied to the outer drum is lower than the lower end of the internal drum, the processing liquid is pumped up from the bottom of the outer tank by the liquid pumping upper part, The liquid can be sprayed from the top of the drum to uniformly infiltrate the material to be processed, and a low bath ratio can be realized without using a pump, and soft processing can be performed without hitting the material to be processed into the tank. A drum rotating textile product processing apparatus is provided.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, dyeing is performed by loading an object to be treated, such as an object to be dyed, on a drum as an inner cylinder rotatably provided around a horizontal axis in the outer cylinder and rotationally driving the drum. In a textile processing apparatus that performs other processing, a plurality of liquid pumping upper portions are provided between the outer drum and a closed portion at the rear end of the drum, and these liquid pumping upper portions are communicated with each other through respective communication holes. A drum rotary textile product processing apparatus provided with a liquid jetting mechanism in which a plurality of bank-like projections extending along the entire length of the drum is provided, and a number of liquid jets are provided at the tips of the bank-like projections.
[0013]
In the second aspect of the invention, a drum rotary type fiber product processing apparatus is provided in which half of a plurality of liquid pumping tops are aligned with the rotation direction of the drum and the liquid pumping top opening is opened, and the rest is provided in the reverse direction.
[0014]
In the third aspect of the invention, a large number of liquid jets provided at the tip of the bank-like protrusion are provided equally on both sides of the tip of the protrusion.

In the fourth invention, the plurality of liquid pumping upper portions each include a pumping port between the drum and the outer tub, and a curved introduction portion following the pumping port.
[0016]
(Function)
In the first aspect of the invention, since a plurality of liquid pumping upper portions are provided between the outer drum and the closed portion at the rear end of the drum, even if the processing liquid level of the dye solution supplied to the outer drum is lower than the lower end of the drum, Processing can be performed by supplying processing liquid into the drum through the upper part of the pump. Even when there is no processing liquid in the drum of the inner cylinder from the beginning, processing can be performed by supplying the liquid from the upper part of the liquid pump.
[0017]
The treatment liquid pumped up from the upper part of the liquid is introduced into the bank-like protrusion from the communication hole and ejected from the liquid outlet at the tip of the bank-like protrusion extending along the inner wall of the drum. The processing liquid is evenly ejected and can be directly supplied to the object to be processed.
[0018]
In the drum, the object to be processed is scraped up by the bank-like protrusions, and can be sufficiently changed in position or lifted so as to be sufficiently in contact with the processing liquid.
[0019]
As described above, by providing the liquid jetting mechanism including the liquid pumping upper part, the bank-like projection and the liquid jetting port, it is possible to reliably perform the processing with a low bath ratio without using a pump.
[0020]
In the second aspect of the invention, since the liquid jets provided at the projection tip of the bank-like projection are equally provided on both sides of the projection tip, the processing liquid is ejected only from the one side liquid jet according to the rotational position of the drum. Alternatively, the liquid is ejected from the liquid ejection ports on both sides to achieve uniform penetration of the processing liquid into the object to be processed.
[0021]
In the third aspect of the invention, since many liquid ejection ports provided at the projection tip of the bank-like projection portion are provided equally on both sides of the projection tip, the ejection can be evenly performed regardless of the direction of rotation of the drum. It has become.
