Abstract

PURPOSE:To perform uniform scouring and thinning treatment without causing folding crease, scratch defect and fluffing by placing rotors separated from a horizontal main shaft in a treating tank and extending a winding core of woven or knit fabric between the rotors in a state rotatable on its own axis. CONSTITUTION:Steam is blown into a treating liquid 11 in a treating tank 1 through a steam-blowing pipe 14 and the liquid is uniformly heated by actuating a circulation pump 13. Separately, a rotary axis 41 of a perforated hollow winding tube 4 holding a treating woven or knit fabric 5 wound on the tube is placed via a bearing 31 and a fixing tool 32 on a pair of rotors 3a, 3b oppositely placed interposing a prescribed gap between the horizontal main shaft 2 in the treating tank 1. A motor 21 is started to rotate the main shaft 2 and, at the same time, the rotation of a transmission gear 33 engaging with a stationary gear 35 is transmitted to the rotary shaft 41 to rotate the winding tube 4 on its own axis. The woven or knit fabric 5 is alternately introduced into the treating liquid 11 and air to enable uniform scouring and thinning treatment of the fabric.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for scouring and reducing a woven or knitted material.

[0002]

2. Description of the Related Art Generally, one lot of a woven or knitted fabric having a small processing quantity is subjected to scouring and weight reduction, or a fine count yarn is used such as a runn and has a fine weave density, or a fine denier like a gauze. -It is common practice in the industry to use a batch method for scouring and weight reduction of woven and knitted fabrics, because the entanglement between filaments is weak when using rumonofilaments and defects such as misalignment and skew skew are likely to occur during processing. . There are three types of equipment used for batch processing, Wins, Jigger and Beam, and the type is selected according to the purpose.

[0003]

As described above, there are three types of apparatuses for performing the scouring / reducing treatment of the woven or knitted material by the batch method, that is, Wins type, Jigger type, and Beam type. Of these, the Wins type is one in which the end and end of the fabric are sewn together by sewing the front end and the end of the woven fabric, and the treatment is performed while the bath is being transferred using a rotary reel. The Jigger method is a method in which two rolls are provided in the tank, and the spread work piece is alternately wound from one roll to the other for processing.

In both of the above-mentioned two methods, since the workpiece is transferred in the bath, tensile tension is applied due to liquid resistance or the like, and bending, skewing, stretching, or folding wrinkles easily occur. Has a problem that it causes scratches and fluffs on the workpiece due to contact or friction with the machine wall. Therefore, it is extremely difficult to carry out scouring / weight reduction treatment by these two methods for a woven fabric having a structure in which misalignment is likely to occur, such as a runner and a gauze. As a solution to the above-mentioned problems, it is suitable to use a beam method that does not involve the transfer of the workpiece during processing.

However, the beam method also has the following problems. For example, when the treatment liquid is pressure-fed from the outer side to the inner side of the work piece wound on the porous beam or vice versa, the treatment liquid has a strong tendency to pass only through a specific path, May cause processing spots.
Further, once such a specific path is generated, the strong liquid flow promotes the misalignment of the path portion, which causes a defect in appearance called so-called moire.

As a method for preventing the above problems, a mechanism for rotating a beam inside the tank has been considered, but a special mechanism for rotating a heavy beam at a constant speed is required, Further, a complicated seal mechanism or the like for feeding the high-pressure machining liquid without leaking to the rotating beam is required, which increases the manufacturing cost. Further, in the beam type, there is a range of optimum processing quantity peculiar to the device, and if the quantity is insufficient or exceeds the range, uniform processing cannot be performed. Further, even if it is within the limit range, it is practically impossible to wind many kinds of products on one beam and to process them at the same time. Not suitable for processing small lots.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. <B> Treatment Tank In the treatment tank 1, a treatment liquid 11 for scouring / reducing the woven / knitted fabric is supplied. As shown in FIG. 1, the liquid level of the treatment liquid 11 is set to a height that secures a space in the upper portion of the treatment tank 1 that allows the entire wound tube to be exposed to the air. Further, in order to prevent the liquid level from rising during the processing and changing the timing of the time in air / in the liquid, an overflow type drain port 12 for holding the liquid level capable of adjusting the vertical position. To provide. In addition, a circulation pump 1 for circulating the treatment liquid 11 in the treatment tank 1.
3. The above is blown into the treatment tank 1, and a blow-in pipe 14 for heating the treatment liquid 11 is provided.

<B> Main Spindle The main shaft 2 penetrates the inside of the processing tank 1 and is installed in the horizontal direction so as to be rotatable by the motor 21. The main shaft 2 is provided at a position where it is flooded with the processing liquid 11. The motor 21 can be controlled in rotation speed and can be installed at any rotation speed, but it is usually desirable to use it in the range of 0.1 R.Pm to 2 R.Pm.

<C> A pair of rotating bodies 3a and 3b are fixed to the rotating body main shaft 2 with a predetermined space. For example, two discs are arranged in the rotating bodies 3a and 3b so as to face each other at a predetermined interval, and the main shaft 2 penetrates through the central portion thereof. As shown in FIG. 2, the diameter of the disk is such that the upper part thereof is exposed to the air from the liquid surface of the processing liquid 11. A plurality of bearings 31 that rotatably support one end of a rotating shaft 41 of the winding tube 4 described later are provided along the peripheral edge of the one rotating body 3b.

A fixing member 32 is rotatably provided on the other rotating body 3a at a position corresponding to the bearing 31. The fixture 32 serves to fix the other end of the rotary shaft 41 of the winding tube 4 and to transmit the rotational force of the small transmission gear 33 to the rotary shaft 41 of the winding tube 4 via the transmission shaft 34. have.
The small transmission gear 33 meshes with a large stationary gear 35 provided in the processing tank 1. The ratio between the small transmission gear 33 and the large stationary gear 35 is not uniquely determined, but usually, the rotation of the winding tube 4 is 10 to 2 per rotation of the rotating body 3.
It is desirable to set the range to 0 times.

<D> Winding Tube The winding tube 4 is a perforated tube body around which the woven or knitted material 5 is wound. Desirably, as shown in FIG. 3, the winding tube 4 has a plurality of holes 42 for communicating the hollow portion with the outside on the surface of the hollow tubular body.
Use the one that was opened. The axis of the winding tube 4 has a rotating shaft 4
1 penetrates through, and one end of the rotating shaft 41 has a rotating body 3b.
It is rotatably mounted on the bearing 31 and the other end is fixed to the fixture 32 of the rotating body 3b so as to extend between the rotating bodies 3a and 3b in parallel with the main shaft 2. As a result, the transmission gear 33 revolves around the stationary gear 35 while rotating around the stationary gear 35, and the transmission shaft 34
Since the rotating shaft 41 of the winding tube 4 is rotated via the fixing portion 32, the winding tube 4 revolves around the main shaft 2 and rotates by the rotation of the main shaft 2.

[0014]

As shown in FIG. 1, the treatment liquid 11 is placed in the treatment tank 1.
Put in, steam is spouted from the steam blowing pipe 14 to heat,
Further, the treatment liquid 11 is circulated by a circulation pump 13 in order to make the concentration and temperature distribution of the treatment liquid 11 uniform. The woven or knitted material 5 is wound around the winding tube 4 and is installed between the rotating bodies 3a and 3b. At this time, a plurality of winding tubes 4 can be installed, and if the processing conditions are the same, it is also possible to simultaneously process many kinds.

When the winding tube 4 is set, the motor 2
1 is operated and the spindle 2 is rotated. by this,
The winding tube 4 rotates around the main shaft 2 via the rotating bodies 3a and 3b, and alternately enters and leaves the processing liquid 11 and the air. When in the treatment liquid 11, the treatment liquid 11 flows through the five layers of the woven and knitted fabric toward the inside of the winding tube 4 by the hydrostatic pressure, and once the treatment liquid 11 comes out of the treatment liquid 11 into the air, it is gravity-driven. The liquid in the winding tube 4 flows out toward the outside of the 5 layer of the woven or knitted fabric. Therefore, the impregnation of the treatment liquid 11 and the drainage can be repeatedly performed without a special liquid feeding mechanism such as a pump.

In addition, since the winding tube 4 is always rotating on its own axis, the treatment liquid 11 does not pass through only the specific path of the five layers of the woven or knitted fabric, and uniform treatment can be performed. Further, since the woven / knitted fabric 5 does not have friction or contact with the device during processing, and it is not necessary to press the processing liquid 11 by a pressure pump, the woven / knitted fabric 5 has creases, scratches, fluffs, misalignment, etc. There is no appearance defect.

[0017]
