DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming fine and irregular wrinkles on a fabric.

[0002]

2. Description of the Related Art In general, a resin precondensate (crosslinking agent), formalin, and the like are widely used for wrinkling a fabric. On the other hand, as a method of adding irregular wrinkles to fabric,
A method in which a woven fabric is bundled and then buckled, and then heat-set in a compressed state (Japanese Patent Application Laid-Open No. 52-14795).
No.) is also disclosed. In addition, scouring, bleaching,
A method of circulating the processing liquid by reducing the pressure in the processing tank with a vacuum pump when performing processing such as weight reduction (JP-A-5-132848)
No.) also exists.

[0003]

In the case of using the above conventional crosslinking agent or formalin, wrinkles are fixed by an ether bond (crosslinking) between a methylol group of a resin and an OH group of cellulose. During the use of the wrinkled fabric, formalin is generated due to hydrolysis of the cross-linking agent, and there is a risk of skin injury, discoloration and decrease in whiteness, decrease in water absorption / hygroscopicity, strength embrittlement, etc. The durability of the wrinkle shape was also poor.

[0004] The method disclosed in Japanese Patent Application Laid-Open No. 52-11479 is intended only for wrinkling.
Although the bundled fabric is buckled, irregular wrinkles cannot be obtained because the fabric is simply heat-set without using water, or the fabric is previously resin-treated with dimethylol ethylene urea. However, there is a problem that the wrinkles are formed only by buckling the dry bundled cloth and the wrinkles are easily removed by washing with hot water. In this method, means for reducing the pressure in the treatment tank as well as water is not employed.

Further, the method disclosed in Japanese Patent Application Laid-Open No. 5-132848 is a general processing means such as scouring, bleaching, and weight reduction for textile products. Although a means of performing wrinkling is employed, it does not relate to wrinkling, and no technical idea of performing wrinkling in a process preceding this processing is disclosed at all.

[0006]

According to the present invention, wrinkling can be performed in the same processing tank prior to general processing such as scouring, bleaching, and weight reduction of a conventional textile product. upon attaching process, by spraying sodium hydroxide to promote the plastic deformation for the fabric to the fabric which focuses the water containing in specific concentrations, impregnated with water containing the sodium hydroxide particular
The bunched cloth in the water-containing state is continuously aligned and laminated on the receiving plate in the processing tank while buckling by the synergistic action of its own weight and the feeding speed, and the inside of the processing tank is lightly compressed. The above-mentioned problems are solved by sealing, depressurizing by vacuuming and heat-treating.

That is, the present invention is a method for wrinkling a fabric comprising the following steps (1) to (6). (1) The fabric is suspended as a rope-shaped bundled cloth toward a processing tank via an S-type drive roll and a roll-in roll, and (2) a ring-shaped shower disposed above the processing tank with respect to the suspended cloth being suspended. Water containing 5 to 15 g / l of caustic soda is sprayed from the outer periphery of the bundle and impregnated with
(3) A bundled cloth impregnated with water containing caustic soda is discharged and dropped at a predetermined feeding speed from a swingable discharge port of a piler to reduce the water permeability in the treatment tank. About 20 to 30% lower than the discharge drop speed of the bundled cloth
(4) buckling of the bundled cloth on the receiving plate by the synergistic effect of the weight of the bundled cloth impregnated with water containing caustic soda and the feeding speed; (5) The treatment tank is pressed from above the laminated bundle of bundles with a water-permeable presser lid so that buckling of the bundle of bundles is not restored. (6) The inside of the processing tank is evacuated and heated to boil the water in the processing tank and then cooled to fix the buckling of the stacked bundles, thereby making it fine and irregular.

In the figure, 45 is an overflow valve, 46 is a liquid level gauge, 47 is a safety valve, and 48 is a pressure gauge.

The wrinkling of the fabric in the present invention is performed according to the following procedure. (1) The gantry 21 is moved along the rail 35 so that the center of the piler 10 is aligned with the center of the processing tank 15, and the basket 3 containing the bundled cloth 2 in which the fabric is previously bound in a rope shape is placed beside the gantry 21. Approach.

(2) The leading end of the bundling cloth 2 is pulled out of the basket 3, wound around the S-type driving roll 1, and hangs over the processing tank 15 via the rewinding roll 4 above the S-type driving roll 1. It is sent to the piler 10 and hangs downward from the discharge port 11 through the discharge pipe 12.

(3) The S-type drive roll 1 and the feed-in roll 4 are driven to feed out the bundle 2 at a speed of about 200 m / min.

(4) 5 to 15 g / l of caustic soda is sent together with water to the ring pipe 6 of the ring-shaped shower 5 via the hose 8 and is sprayed obliquely downward from the nozzle 7 onto the outer periphery of the traveling bundle 2. I do.

When the amount of the caustic soda is less than 5 g / l, the durability of wrinkles is poor, and when it exceeds 15 g / l, the shrinkage of the whole fabric becomes large and the wrinkles become inconspicuous. Then, the injection amount of water containing caustic soda at this time is set so as to be about 180 to 200% with respect to the bundled cloth 2.

(5) While discharging the bundled cloth 2 in the water-containing state from the discharge port 11 of the piler 10 at a speed of about 200 m / min, the discharge port 11 is discharged at a speed of about 140 to 160 m / min. , The weight of the bundled cloth 2 impregnated with water containing caustic soda, and the synergistic effect of the unwinding speed, continuously buckle the bundled cloth 2 on the receiving plate 9 in the processing tank 15. And layer them in a chrysanthemum pattern.

If the horizontal moving speed of the discharge port 11 is 30% or more lower than the discharge falling speed of the bundle 2, the bundle 2 is not smoothly stacked on the receiving plate 9 in a chrysanthemum pattern.
If it is 0% or less, sufficient buckling cannot be obtained, and fine wrinkles cannot be obtained.

(6) From above the bundled cloth 2 in a buckled and stacked state, FIG.
The handle 18 is operated as shown in FIG.
7, the bundled cloth 2 is lightly pressed with a pressure of about 90 g / cm ² , and the upper lid 20 is closed so that wrinkles due to buckling are not restored.

(7) The inside of the processing tank 15 is evacuated to about −600 to 700 mm / Hg to reduce the pressure.

(8) Then, steam is injected into the heat exchanger 40, and the water in the treatment tank is heated to 110 ° C. to 130 ° C. for about 120 minutes to 180
After boiling for a minute, the pressing by the presser lid 19 is released, and cooled by flowing cold water.

[0033]

The fine and irregular wrinkles imparted to the fabric by the method of the present invention are approximately 1 mm in a gentle curve that is almost straight.
From about 30 mm in length to irregularly mixed wrinkles, as if they had a wrinkle pattern similar to the surface of a melon (this is called "melon wrinkles"). Ironing, except for the "/ cotton" fabrics, will not disappear semi-permanently. This is presumed to be because strong hydrogen bonds or ether bonds are formed between the cellulose molecules and the shape is fixed by the activation of caustic soda on the cellulose molecules of the fabric.

[0034]

EXAMPLES As fabric, rayon / linen (80/20),
100% cotton, tetron / cotton (65/35) and rayon
Using four types of 100%, wrinkle processing under the following conditions
went. Feeding speed of S-type drive roll: 200 m / min Amount of caustic soda added to water: 10 g / l Water content of bundled cloth: 200% Moving speed of discharge port of piler: 150 m / min Layering state of bundled cloth on receiving plate : Chrysanthemum flower Presser cover pressure: 90g / cm²  Pressure in processing tank (vacuum condition): -650 mm / Hg Heating means and time: steam 150 minutes Cooling means and time: water passing 30 minutes

[0035] Mercerization and ammonia treatment were performed as a pretreatment for a 100% cotton fabric .

[0036]

[Test results] The G method (electric washing machine method) of various shrinkage test methods for woven fabrics specified in JIS L-1042 for various fabrics provided with fine and irregular melon wrinkles according to the above-described examples. Table 1 shows the results of tests performed in accordance with.

[0037]

[Table 1]

As is clear from the above test results, many of the fabrics were contracted even after being washed 10 times, and it was found that wrinkles hardly changed. In addition,
In the case of 100% rayon, both the vertical and horizontal lengths are slightly increased, but the rate of increase is also 5/1000.
~ 7/1000, and the one with this degree of elongation is
Usually, it was not determined to be "stretched", and in fact, when visually observed, the state of melon wrinkles was almost the same as that before washing.

When the above-mentioned various types of melon wrinkled fabric were ironed each time of washing,
The wrinkles were slightly weakened for the “Tetron / cotton” cloth, but the wrinkle state was hardly changed for the other cloths.

[0040]

In the method for wrinkling a fabric according to the present invention, without using a shape fixing agent such as formalin,
Since the fiber itself is physically and chemically modified to maintain the wrinkle shape, there are no problems as with conventional products, and the wrinkle shape is not permanently damaged by washing or ironing, dyeing properties etc. Which does not have any adverse effect.

Further, crinkled method of fabric according to the present invention does not require a separate special crinkled steps as in the conventional, scouring, bleaching, melons in time with the treatment process of weight loss, such as the same treatment tank wrinkles because reproduced automatically, operation efficiency can be dramatically improved, further, since it is not impaired cellulose inherent hygroscopic is not used a special shape fixing agent such as a resin, refreshing The touch can be maintained.

Therefore, it can be said that the industrial applicability of the present invention is very large.
