[Detailed description of the invention]

(1) Purpose of the invention Industrial application field The method of the present invention is for dyeing cheese using centrifugal force.
Concerning scouring, bleaching and other processing methods. Conventional technology: Regarding the dyeing method using centrifugal force,
There is a publication number 37388. This patent discloses a dyeing method in which a woven or knitted fabric is wrapped and treated on a perforated beam. In addition, the applicant has filed Utility Application No. 59-107036 (Utility Model Application No. 107036/1983) as a cheese processing device using centrifugal force.
24492). Problems to be Solved by the Invention According to the above-mentioned Japanese Patent Publication No. 46-37388, the actual measurement data of the flow rate and rotational speed of the dyed material shows that the square of the rotational speed and the flow rate are directly proportional, and that the flow rate and level dyeing are directly proportional. Discloses a diagram showing the relationship with time. In general, in the centrifugal dyeing method, if the winding density is reduced and the number of revolutions is increased, the flow rate will naturally increase and level dyeing properties will be obtained. However, regarding treatments such as cheese staining,
Due to the characteristics of fibers, the above principles may not necessarily apply.
Depending on the winding density and rotation speed, the cheese shape may become distorted or sag, which greatly affects level dyeing. In order to solve the above-mentioned problems, the present invention actually measures the relationship between the winding density of cheese, the rotation speed, and the flow rate for each type of fiber, and by setting these relationships appropriately, it is possible to maintain a stable cheese shape. Moreover, the purpose is to perform uniform processing by obtaining an appropriate flow rate. (2) Means for Solving the Constituent Problems of the Invention In order to achieve the above object, the method of the present invention uses a porous bobbin around a porous processing liquid ejection pipe provided in the processing liquid circulation system. A process in which a cheese wrapped in a cheese is set, the cheese is connected to a drive source and rotated at high speed, and a processing liquid from the processing liquid spouting pipe is passed through from the inside of the cheese to the outside for dyeing or other processing. In the method, depending on the type of yarn, the cheese winding density ρ (g/cm ³ ) is 0.3 or more, and the rotation speed (rpm)
This is a method for dyeing and other processing of cheese using centrifugal force that satisfies the condition of 500 to 2000. Effect In the method of the present invention, the winding density can be adjusted depending on the type of yarn.
The weight was 0.3 g/cm ³ or more, and the rotation speed was 500 rpm or more. In general, the higher the rotation speed, the higher the flow rate and the more level dyeing properties can be obtained. However, with regard to acrylic fiber yarns and their blended yarns, due to the characteristics of the yarns, which have a low fiber softening point, are easy to set, and flow through easily. The density is
Relatively tightly wound at 0.4g/cm2 or ^more , rotation speed is 500~
Even at a low rotational speed of 700 rpm, a suitable flow-through effect can be obtained, and good results can be obtained by preventing deformation. In addition, when using wool yarn or its blended yarn, the winding density should be 0.35 g/ ^cm3 or more, and the rotation speed should be 700 to 1000 rpm.
is appropriate. Furthermore, in the case of cellulose fiber yarns and their blended yarns, the winding density should be 0.3 g/cm ³ or more.
A suitable rotation speed is 1000 to 2000 rpm. Furthermore, in the case of polyester fiber yarns, polyamide fiber yarns, and blended yarns thereof, good results can be obtained with a winding density of 0.35 g/cm ³ or more and a rotation speed of 800 to 2000 rpm. Example The centrifugal dyeing machine used in the example of the present invention has the configuration shown in the drawings. That is, a processing tank 1 having a lid body 2 at one end opening and a bearing part 3 supporting a hollow shaft 9 at the other end closed part, and a processing liquid storage provided in the lower part of the processing tank. part 4, pump 5, and the hollow shaft 9
A processing liquid circulation passage 6 consisting of piping connecting the
In the processing tank 1, there is a porous rotating tube 7 with one end as an open end for loading the processed material 8 and the other side fixed to a hollow shaft 9; a processing liquid ejection pipe 10 extending over almost the entire length of the processing liquid circulation passage 6 and connected to the processing liquid circulation passage 6;
A holding plate 13 is provided so as to contact the edge of the cheese 12 loaded in circumscribed contact with the front rotary tube 7, and a presser plate 13 is provided so as to be in contact with the edge of the cheese 12 loaded so as to be circumscribed in the front rotary tube 7. The loaded cheese 12 is rotated at high speed together with the rotary tube 7 to perform dyeing and other treatments. Note that 14 is a fixture, and 15 is a drive source such as a motor. 16 indicates a heat exchanger. As described above, a plurality of cheeses 12 are loaded on the outer periphery of the rotary tube 7, and a presser plate 13 and a fixing metal fitting 14 are mounted on the outer circumference of the rotary tube 7.
If it is fixed using , smooth rotation can be obtained without causing unbalance even during high speed rotation. When the lid 2 of the processing tank 1 is closed and the switch is turned on, the processing liquid is circulated in the processing tank 1 through the processing liquid circulation passage 6, making it possible to carry out high-temperature dyeing processing at an extremely low bath ratio. By storing the processing liquid in the storage section 4,
The pump 5 can operate without cavitation. Drying can also be performed by circulating hot air or the like instead of the treatment liquid. A plurality of pieces of cheese 12 wound around the bobbin 11 can be processed at the same time, and the rotating tube 7 is rotated at high speed, and the processing liquid jetted from the processing liquid spouting pipe 10 is passed straight through the cheese portion through the bobbin 11. It is processed by Example 1 (In the case of acrylic fiber yarn and its blended yarn) Bobbin shape φ80 Bobbin Yarn type/amount 100% acrylic yarn (Asahi Kasei, Cashmilon)
1200g roll The winding density and rotation speed are as shown in the table. Results As is clear from the table, the winding density was 0.4 g/cm ³
If it is less than that, it will lose its shape or become loose. Regarding the winding density, 0.4 g/cm ³ or more was good, and the flow rate was also 15 to 25/min·Kg. Also, the rotation speed is good at 500 to 700 rpm,
If the speed exceeds 1000 rpm, the amount of stagnation becomes large, causing liquid leakage and uneven dyeing. Example 2 (In the case of wool yarn and its blended yarn) Bobbin shape φ80 bobbin Yarn type/quantity 100% wool 42/2 1200g winding Acid dye dyeing The winding density and rotation speed are as shown in the table. Results As is clear from the table, the winding density is 0.35g/ ^cm3 or more,
When the rotation speed was 700 to 1000 rpm, there was no deformation or sagging, and the flow rate was 20 to 30/min・Kg, which enabled uniform processing. Example 3 (In the case of cellulose fiber yarn and its blended yarn) Bobbin shape φ80 bobbin yarn type/amount Cotton yarn 40/2 1200g winding Direct dye, reactive dye, thren dye Dyeing The winding density and rotation speed are as shown in the table. It is. Results As is clear from the table, the winding density is 0.30g/ ^cm3 or more,
When the rotation speed was 1000 to 2000 rpm, there was no deformation or sagging, and the flow rate was 20 to 30/min・Kg, which enabled uniform processing. Example 4 (In the case of polyester fiber yarn, polyamide fiber yarn, and blended yarn thereof) Bobbin shape φ80 bobbin Yarn type/amount Polyester filament 1200 g wound Disperse dye dyeing The winding density and rotation speed are as shown in the table. Results As is clear from the table, the winding density is 0.35g/ ^cm3 or more,
When the rotation speed was 800 to 2000 rpm, there was no deformation or sagging, and the flow rate was 20 to 30/min・Kg, which enabled uniform processing. A table regarding winding density and rotation speed is shown below.

[Table] △: Slight deformation and deformation occur.
×: Fatigue and deformation occur.
As shown in the above examples, in the case of acrylic fiber yarn, special consideration is required due to the characteristics of the acrylic yarn in terms of winding density and rotation speed. The same applies to wool yarn, cotton yarn, and polyester yarn. (3) Effects of the invention Since the method of the present invention has the above configuration,
By selecting an appropriate winding density and rotation speed depending on the type of yarn to be treated, the flow rate of the treatment liquid can be kept constant within a range that allows level dyeing, and the cheese no longer loses its shape or sag. Conventionally, in the case of centrifugal dyeing machines, cheese is loaded as is, and it has been difficult to flow the wrapped cheese from the inside to the outside, but as long as the conditions of the method of the present invention are met, there will be no uneven dyeing. It has now become possible to provide a processing method that does not cause deformation. In addition, special yarns (filament yarns) could not be dyed using the conventional cheese dyeing method due to poor liquid flow.
This was made possible by using the method of the present invention.
