Description

[Detailed description of the invention]

TECHNICAL FIELD The present invention relates to a continuous crimp processing apparatus for cloth, which is configured to be able to continuously crimp long lengths of cloth with good quality. For example, the present inventors have described 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 produce a texture on the fabric. A number of issues have already been raised, and some of them are known to the public. However, since the already known graining processing apparatus circulates the processed fabric, which is made into endless pieces of fabric of a predetermined length, in a closed pot using a winch or the like, conventional apparatuses cannot However, it was not possible to embed a long piece of fabric continuously. That is, 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 the necessity of 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 large amount of wasted 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 keep the temperature conditions constant for each change, and it is difficult to Another drawback was that it was not possible to uniformly embed each 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, not large grains but thin grains. The third purpose is
The aim is to provide low-cost products that save heat, energy, and labor. That is, the first objective of the present invention, which is continuous processing of a long workpiece cloth, can be achieved by developing a continuous processing apparatus. Therefore, this continuous processing apparatus will be described in detail later. The present inventor has demonstrated that in order to achieve the second objective of high-quality graining, the wet and heat processing temperature of the fabric to be processed must be gradually increased. For example, a 100% polyester fabric (twill) is used as the fabric to be processed, and it is embossed under various hot water treatment conditions, such as A, B, C, D, E, and F. In the case of aging, data as shown in FIG. 1 was obtained. Furthermore, A, B, C, D,
The processing conditions of E and F are shown in the chart below. That is, in condition A, the sample was treated with hot water at 100°C for 15 minutes and then steamed with high pressure steam at 150°C for 3 minutes. Condition B is 90°C boiling water for 5 minutes, then 100°C boiling water for 10 minutes, and then 150°C.
Steamed for 3 minutes using high pressure steam. Condition C: 80℃ boiling water for 5 minutes, 90℃ boiling water for 5 minutes, then 100℃ boiling water for 5 minutes.
After being treated with boiling water for 3 minutes, it was steamed with high pressure steam at 150°C for 3 minutes. Condition D is 70℃ boiling water for 5 minutes, then 80℃ boiling water for 5 minutes, then 90℃ boiling water for 5 minutes.
minutes, then treated with boiling water at 100℃ for 5 minutes, and then heated with high pressure steam at 150℃ for 3 minutes.
I steamed it for a minute. In condition E, the sample was treated with hot water at 60° C. for 5 minutes, and then subjected to the same treatment as in condition D above. F condition is to gradually increase the temperature of hot water from 60℃ to 100℃ in 15 minutes, then to 100℃ for 5 minutes.
After being treated with boiling water for a minute, it was steamed with high pressure steam at 150°C for 3 minutes.

【table】

[Table] Observing the shrinkage rate of the fabric under each of the above treatment conditions, that is, the graining and clamp recovery in Figure 1, it is found that the clamp recovery and wrinkle recovery are insufficient under conditions A and B, while they are slightly better under condition C. Furthermore, under each condition D, E, and F, extremely good clamp recovery and grain removal were achieved. Next, the relationship between the processing time and shrinkage rate of hot water treatment and steaming is explained in Figure 2.The shrinkage of the fabric is completed in around 8 minutes at any processing temperature, and even if the processing time is extended beyond that, the shrinkage does not continue. The degree will not change significantly. Figure 3 shows the relationship between fabric shrinkage treatment temperature and shrinkage rate.
The shrinkage rate does not change significantly at temperatures above 100°C. Judging comprehensively based on the above data,
When graining a fabric, the temperature of the fabric to be processed is raised stepwise from about 60℃ to 100℃, or the fabric is passed through each heated treatment solution for about 15 minutes, and then heated to 150℃. Fine grains of good quality were formed by steaming for around 3 minutes with steam at around ℃. Next, the graining processing apparatus according to the present invention will be explained in detail based on the embodiment shown in FIGS. 4 and 5. In FIG. 4, A, B, and C are all liquid processing tanks of the same structure, and inside these liquid processing tanks, there are a pair of endless net conveyors 2 and 3 is arranged, and the fabric 4 is placed in the gap formed by the upper and lower net conveyors 2 and 3.
The net conveyor rotates the net conveyor and conveys it without tension.
In addition, an air injection pipe 5 is provided in the liquid tank 1 for blowing air toward the fabric being transferred by the upper and lower net conveyors 2 and 3. The fabric 4 is subjected to liquid treatment while being relaxed in the liquid.
Since the liquid processing tanks B and C have the same structure as the liquid processing tank A, a description of their structure will be omitted. D is 150 inside
A high-pressure steamer that maintains high-pressure moist heat around ℃,
This high-pressure steamer is equipped with sealing devices 6 and 7 that can continuously introduce and take out the fabric while maintaining high-pressure, moist heat. Furthermore, a high-pressure liquid treatment tank 8 having the same structure as the liquid treatment tank A is provided in this high-pressure steamer D, and is used to relax the fabric passing through this high-pressure steamer. E is a washing tank with the same structure as liquid treatment tank A,
F is a drying room. In this apparatus, when cloth 4 is grained, the liquid temperature in liquid treatment tank A is set at approximately 60°C, the liquid temperature in liquid processing tank B is set at approximately 80°C, and the liquid temperature in liquid processing tank C is set at approximately 60°C.
After setting the temperature in the high-pressure steamer D to 100°C and further setting the temperature in the high-pressure steamer D to about 150°C, the fabric 4 is passed through each liquid treatment tank for about 5 minutes, and the temperature inside the high-pressure steamer is set to about 300°C.
Set the retention rate of the fabric in the tank so that it passes in about 1 minute. When the fabric is continuously passed through the apparatus described above and subjected to moist heat treatment using each liquid treatment tank and a high-pressure steamer, the fabric is relaxed while being acted on with a liquid whose temperature gradually increases, resulting in a fine grain of good quality. There is an effect that can be done. Furthermore, the apparatus according to the present invention can consistently and continuously embed a long fabric, thereby eliminating the need for replacing heat energy, thereby achieving energy savings and labor savings. Moreover, it has the effect of continuously and evenly graining the grain. In the embodiment shown in FIG.
Although the structure is different from C and 8, there is no difference in that the fabric is allowed to move through the liquid while being relaxed, and the temperature is gradually increased in each liquid treatment tank. That is, the liquid processing tank in this embodiment is the liquid tank 1.
0 is formed into a substantially U-shape, the lower bottom of which is pivoted by a support shaft 11, and the upper end thereof is provided with an eccentric swinging rod 12.
By connecting the liquid tank 10 and swinging the liquid tank 10 by the operation of the eccentric swinging rod 12,
The fabric 4 supplied therein is relaxed in the liquid tank while advancing toward the outlet and being drawn out. Therefore, the same processing as in the first embodiment can be performed in this embodiment as well. It goes without saying that the relaxing liquid treatment tank is not limited to the above two embodiments, and that various other relaxing liquid treatment tanks can be used.
