TECHNICAL FIELD This invention relates to the processing method of the to-be-processed object in textile processing, and the nonwoven fabric roll used for it. In conventional textile processing, there are various processes such as an immersion process, a washing process, and a good quality treatment, such as a neutralization process. It is a present situation that various treatments mentioned above are performed by immersing the to-be-processed object in the water and process liquid.

Therefore, even in the case of relatively simple processing such as the simple processing of the processing or the partial processing of the processed object, the use of the above-described processing tank is required in reality, which saves work or energy, rationalizes the process, It is a problem of reality that low bathing expenses are being advocated.

In particular, in the various processes in textile processing, so-called energy is consumed in the so-called drying process, so it is possible to save fuel costs by improving the rate of squeezing out the water of the object in the so-called dehydration process. It is very helpful for energy saving and resource saving, such as productivity improvement, water and treatment liquid reduction, and how to take water in this dehydration process is a big problem.

Therefore, as a substitute for the conventional rubber helper in this dewatering process, a roll in which a large number of nonwoven fabrics are pressed in a crimped state on a axial body of a nonwoven fabric roll has recently been proposed, and has a considerable dewatering effect. have.

However, also in this nonwoven fabric, this is only to take advantage of the absorbency possessed by the nonwoven fabric to the last, and the performance of the absorbent does not exhibit any effect.

For example, when the entire nonwoven fabric roll absorbs moisture, new performances such as failing to perform the above-described performance and thus failing to achieve the original purpose and requiring new auxiliary equipment are generated.

Thus, the present invention provides a method for processing a workpiece and a nonwoven fabric most suitable for a dehydration process during the processing, in the processing of textiles most appropriately when a simple, easy or partial treatment of a workpiece is intended. It is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First of all, for convenience of description, the nonwoven fabric roll shown in FIGS. 7 and 8 is a cylindrical shaft body having bearing portions 2 and 2a at both ends. ) Is provided with a cavity 3 facing in the axial direction, and a plurality of through holes 4 communicating with the cavity 3 described above are drilled on the main surface thereof.

In addition, one side of the shaft main body 1 becomes an opening 5, and this opening 5 communicates with the above-mentioned cavity part 3, and the through-hole opened in the axial direction in one shaft support part 2 at the same time. It is also in communication with (6). The opening 5 communicates with the pumping means and the suction means (not shown) through the through hole 6 of the bearing portion 2.

When the cylinder is roughly described, the piston is pinched into the cavity 3, the at least one bearing portion 2 is made to have a large diameter, and an outlet or the like is provided in the bearing portion.

7 is a side plate attached to one end side of the shaft body 1, and the nonwoven fabric 8 is sequentially superimposed on the side plate 7 in a crimped state, for example, by press molding, and thus the side plate 9 is placed on the other end side. It adheres so that a roller main body is comprised as such both side plates 7 and 9 and several sheets of nonwoven fabrics 8.

In this way, the nonwoven roll of this invention is comprised.

And the bearings which mount the bearing parts 2 and 2a to a processing process, for example, support an appropriate number of nonwoven rollers.

In addition, as shown in FIG. 8, the sub chamber 11 may be provided, and in this example, the spacers 12 that face the axial direction at equal intervals, preferably on the outer circumferential surface of the shaft main body 1, are arranged. ), And the nonwoven fabric 8 is pressed on the spacer 12 in a crimped state to form a roll body.

As a result, a plurality of elongated subsidiary chambers 11 are arranged on the outer circumferential surface of the shaft main body 1 in the axial direction to form a chamber in which fluid is retained. I can do it.

Next, a method for treating dehydrated decontamination, neutralization, etc. by applying the nonwoven fabric rolls (hereinafter referred to simply as a roll) having the above-described configuration shown in FIGS. 1 to 6 will be described. As shown in Fig. 2, when the rollers are installed in a pair in a state in which they are opposed to each other, one of the rolls (A) is discharged (hereinafter, A is the dragon's roll). B) is used for suction. (Hereinafter B shall be a roller for suction).

In this example, a fluid such as water, compressed air, or a treatment liquid is passed through a pump, or the like, through a through hole 6 → an opening 5 → a cavity 3 (→ a through hole 4 →) or a failure ( 11) → roll body So-called, overflows or ejects from the surface of the roll (A) all the time or in a flawless manner. The fluid overflowing in this way comes into contact with and adheres to the processed material C that passes or temporarily stays between the rolls A and B.

At the same time or when intermittently or intermittently the aforesaid fluid is aspirated from the roll B, the fluid passes through the tissue of the workpiece C and is sucked from the surface of the roll B so that the roll body is damaged. (11) (→ through hole (4) →) or cavity (3) → opening (5) → through hole (6), the fluid is aspirated and pumped into a liquid tank or discharge tank (shown) Not discharged).

By this, the to-be-processed object C completes dehydration, dehydration, or water washing, deodorant, chemical | medical agent treatment, etc., and is conveyed to the next process and drying process.

In addition, as shown in FIG. 3, two rolls A are connected, or as shown in FIG. 4, a plurality of rolls A and B are installed so as to face each other. It is also possible to connect several rollers (B) or the like, or to replace any of the rollers (A) and (B) with rubber rollers, etc., so that the method of the present invention can be carried out extensively. The effect of suction can be further improved.

Further, if the method of the present invention is considered in advance, as shown in Fig. 5, the roll groups A and B can be used as a continuous processing system. With respect to the to-be-processed object C conveyed via (13), the fluid containing the 1st, 2nd roll B is first sucked by the same function as mentioned above, and a suction fluid is discharged | emitted through a discharge path.

Next, a new fluid is supplied (flushed, overflowed, etc.) in the third and fourth rolls A to contact and adhere to the water to be treated C, and then the fluid is described in the fifth roll B. When aspirated by the same action as described above, the fluid passes through the tissue of the workpiece C and is sucked into the roll B and discharged through the discharge path.

And the to-be-processed object C which completed the process of one row is conveyed to the next process process and a drying process via the guide roll 14.

In addition, as shown in FIG. 6, the oppositely installed rolls are the rolls (B) and (B), and the dehydration and dehydration method sucked from both sides and the oppositely installed rolls are the rolls (A) and (A). A continuous system such as a water supply liquid supplying from the water or a dewatered water supply not shown but using both methods described above is also possible.

As described in detail above, the method of the present invention enables various processing such as dehydration and dehydration, washing with water, etc. as a suction roll, which passes through the rolls, and sprays the processed object. In particular, it is possible to provide simple or partial processing, which can be expected to simplify and shorten the processing time, improve workability and facilitate work, and reduce the amount of processing liquid, chemicals, calories and power. Becomes

In addition, the uniformity of the adhesion of the treatment liquid and the uniformity of the transmittance can be achieved by the uniform operation of the ejecting means and the suction means, and the uniformity of the quality, the saving of the treatment agent, and the low bath ratio can be achieved. It is also adopted in this type of continuous processing system of the prior art, and the rationalization of the process is expected. On the other hand, in the logic cloth roll, dehydration, dehydration, and the like of the to-be-processed object are performed by absorbing the nonwoven fabric and also by mechanical suction means, so that the dewatering effect of the dehydration, dehydration, and nonwoven fabric roll is improved. It is possible to simplify the structure and to provide an inexpensive nonwoven roll device by eliminating the need for additional equipment such as a doctor knife blade.

It is possible to improve the dewatering and aperture efficiency. For example, in the dyeing processing system, it is possible to expect a reduction in time and calories of the drying process to be performed next.
