Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous crimp processing apparatus for a fabric, which is configured to be able to continuously and high-quality emboss a large length of fabric.

For example, the present inventors have already developed a processing method in which a fabric containing polyester fibers is steamed in the presence of caustic alkali in a high-pressure steamer that applies high-temperature, high-pressure saturated steam to cause the fabric to become embossed. is,
Some of them are known.

However, since the already known graining processing apparatus circulates the processed fabric, which is made into an endless fabric of a predetermined length, in a sealed pot using a wince or the like, the conventional However, it was not possible to embed a long piece of fabric continuously.

In other words, processing a fabric of a predetermined length in a closed pot not only requires the work of loading and unloading the fabric into and out of the pot for each treatment, but also requires opening and closing the closed pot each time the fabric is taken in and out. Moreover, this opening causes the heat inside the pot to be released, resulting in a waste of a large amount of thermal energy.

Furthermore, each time a unit length of fabric is replaced in the kettle, it is necessary to raise the moist heat temperature in the kettle to a predetermined temperature, but in this case, it is difficult to maintain a constant temperature condition for each change. There was also the drawback that it was not possible to uniformly embed a unit length of fabric.

The present invention has been made in view of the above, and its first purpose is to achieve continuous production and uniform processing of graining processing by continuously passing a long workpiece cloth through a predetermined processing device. It is a matter of coercion.

The second purpose is to be able to gradually increase the temperature applied to the fabric to be processed so that high quality graining can be achieved, that is, fine grains are formed instead of large grains.

The third objective is to provide a low-cost product that saves heat, energy, and labor.

The present invention will be explained in detail below based on embodiments shown in the drawings.

In Fig. 1, 1 is the cloth to be wrinkled, for example,
This is a long piece of processed fabric containing polyester fibers.

Reference numeral 2 denotes a liquid tank containing a treatment liquid necessary for embedding the processed fabric 1, for example, a caustic soda aqueous solution.The processed fabric 1 is guided into this liquid tank 2, and the processing liquid is applied to the fabric. 1.

3 is a squeezing roll for squeezing the impregnating liquid with which the fabric 1 to be processed is impregnated into a constant amount.

A is the first grain raising machine, and this first grain raising machine A
A rotary tube 4, which is the main structure of the rotary tube 4, is installed obliquely with a slight downward slope, and openings on both sides of the rotary tube 4 are rotatably supported by support rolls 5.

6 is a pulley provided around the outer circumference of the rotary cylinder 4,
This pulley 6 is connected via a belt 7 to a drive pulley 9 of a motor 8.

10 is a protrusion disposed at a suitable position on the inner peripheral surface of the rotary cylinder 4,
This protrusion 10 is provided for scraping up the fabric and is provided to smooth the friction between the inner surface of the rotary tube 4 and the fabric fed into the rotary tube 4.

Reference numeral 11 denotes a guide for introducing the fabric 1 into the rotation tube 4, and this guide 11 is located at the fabric introduction side opening 4' of the rotation tube 4.

Reference numeral 12 denotes a disk provided around the outer periphery of the fabric outlet side opening 4'' of the rotary cylinder 4, and a brake shoe 13 is provided on this disk 12 so that it can come into contact with it.

The motor 8 is an intermittent operating motor for intermittently operating the rotary cylinder 4 approximately half a turn at a time; however, if a braking force is applied to the disc 12, inertia rotation of the rotary cylinder will not occur and reliable intermittent operation will occur. A rotation is made.

B is a second grain erector installed following the first grain erector A, and the structure of this second grain erector B is the same as that of the first grain erector A. Therefore, the same reference numerals will be given to the corresponding parts and the structural explanation of the second grain erector will be omitted, but the rotation direction of the rotary cylinder 4 of this second grain erector is the same as the rotation of the first grain erector. It is rotated in a direction opposite to that of the cylinder 4.

(Although the embodiment shown in Fig. 1 has been shown with 12 machines, the first grain racker A and the second grain racker B, the present invention is not limited to this, and there are 4 to 5 grain rackers. It is desirable to provide a

The reason will be explained later. Reference numeral 14 denotes a conveyor for transporting the fabric discharged from the final graining machine to the next process.

Further, each of the rotating cylinders 4 is equipped with a heating mechanism, such as a steam blowing pipe (not shown), for maintaining the inside of the rotating cylinders at a predetermined moist heat temperature.

Next, to explain its operation, first, the temperature inside the rotating cylinder of the first grain erector A is adjusted to be lower than the temperature inside the rotary cylinder of the second rasp racker B, and then both rotary cylinders are It is rotated intermittently in the opposite direction, for example, at a speed of about 20 revolutions per minute.

Therefore, the fabric 1 to which a predetermined liquid has been applied in the liquid tank 2 is continuously supplied from the guide 11 into the rotary cylinder 4 of the first embedding machine B.

Since the supplied fabric undergoes intermittent rotation in which the rotating cylinder 4 stops approximately every half rotation, the fabric that has been pulled up from the bottom inside the rotating cylinder to the top reaches the bottom inside the rotating cylinder when the rotating cylinder temporarily stops. The fabric is lowered, and while the striking force and kneading force are repeatedly applied to the fabric, it receives the moist heat in the rotating cylinder and advances toward the outlet 4''.

That is, the fabric is intermittently repeatedly subjected to batting force and kneading force within the rotating cylinder, and is further exposed to moist heat, thereby causing wrinkles to occur on the fabric.

Further, since this first graining machine A performs processing at a relatively low temperature, fine grains begin to appear.

Next, the fabric drawn out from the first grainer A is supplied into the rotary barrel 4 of the second grainer B, but this rotary barrel 4 is connected to the rotary barrel 4 of the first grainer A. The twist in the fabric that occurs in the first embosser B due to the intermittent rotation in the opposite direction is eliminated by passing it through the second embedder B, while the striking force and kneading force continue to act.
Furthermore, in this second grain erector B, a moist heat temperature higher than that in the first grain erector B is applied to produce sharp grains and to heat set the grains.

As mentioned above, the embodiment shown in Fig. 1 is equipped with a first grainer A and a second grainer B, but in order to make a fine grain, the fabric must be heated suddenly. Therefore, in this example, the first grain erector A performs relatively low-temperature treatment, and then the second grain erector A performs high-temperature treatment to form a good grain.

In addition, as shown in Fig. 2, there are four grain racking machines, for example, the first grain racking machine A has a heat and humidity temperature of 55°C, the second grain racking machine B has a heat and humidity temperature of 70°C, and the third grain racking machine has a heat and humidity temperature of 55°C. By setting the moist heat temperature of the graining machine C to 85°C and the moist heat temperature of the fourth graining machine to 95°C, and gradually increasing the moist heat temperature acting on the fabric, finer and better graining can be achieved. We were able to.

In addition, 15 shown in FIG. 2 is a washing machine, and 16 is a drying chamber.

As described above, the present invention includes a rotary cylinder which is open at both ends, and from which a long fabric is sequentially supplied through the opening at one end and led out from the opening at the other end, and this rotary cylinder is intermittently rotated approximately half a turn at a time. Two or more graining machines each consisting of an intermittent drive mechanism for the purpose of the present invention and a heating means for bringing the inside of the rotary cylinder to a predetermined heat and humidity temperature are arranged in series in the axial direction, and furthermore, the temperature in the heat and humidity inside the grainer in front of the grain raising machine can be adjusted to a predetermined temperature. This graining processing device is set to be lower than the moist heat temperature in the rear graining machine, and is driven intermittently in the opposite rotation direction of each graining machine, so that it can consistently and continuously process long fabrics. It is possible to carry out grain processing, which eliminates the need to replace heat energy, resulting in energy savings and labor savings.
Moreover, there is an effect that a uniform graining process is performed continuously.

Furthermore, in the present invention, the grain erector is provided in multiple stages, and the internal temperature of each stage of the grain erector is set to a higher temperature in sequence, so that it is possible to form fine grains of good quality.
