Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides stockings which are designed to repeatedly immerse an object to be dyed stored in a dyeing tank in a dyeing liquid under almost static conditions, and to forcefully drain the object. This paper relates to a method for dyeing knitted products such as knitted products.

+jf= Since then, the conventional dyeing techniques for knit products such as stockings have been the drum-type dyeing machine and the jet dyeing machine.

In the former, a cylindrical dyeing tank (c) is horizontally fixed to the machine base, and a cylindrical rotating tank whose interior is partitioned radially with perforated plates and whose peripheral surface is also made of perforated plates is mounted horizontally.

A means for supplying and draining water to the dyeing tank, a means for supplying the dye and auxiliary agent, a means for heating the dye solution, which is a mixture of water, dye and auxiliary agent, with steam, etc. The cylindrical rotating tank is equipped with a means for rotating it in reverse at regular intervals, and inside the cylindrical rotating tank, articles to be dyed such as stockings placed in dye bags are placed in each dyeing chamber partitioned by perforated plates. After storing the liquid in a well-balanced manner and pouring water until the dye reaches the middle position of the goose-shaped rotating tank, the cylindrical rotating tank is reversed at regular intervals to reverse IF.
-1- By causing the dye solution to flow, the dye solution can be applied uniformly to the object to be dyed in the dyeing tank without any spots.

On the other hand, in the latter method, a basket containing objects to be dyed evenly is submerged in a dye tank configured to allow circulation of the dye liquid, and the flow of the dye liquid is applied to the objects to be dyed in the basket (C). This method dyes the object to be dyed in a stationary state.

However, the conventional technology described above has the following drawbacks.

Drum-type bleaching machines have the following features: (1) Due to the forward and reverse rotation of the m-shaped rotary tank, the dyed objects move within the dyeing chamber, so even if they are wrapped in a dyeing bag, the dyed objects may be pulled, entangled, scratched, etc. occurs.

(1) If the object to be dyed is not evenly filled into the cylinder that is immersed in the color type, the flow of the dye liquid will be uneven, resulting in uneven dyeing.

As stated in (2), 4'O8 In order to prevent color unevenness, skill and sufficient time are required to fill the coating uniformly.

4 Momme invention (IJJ
The object of the present invention is to provide a method for dyeing knitted products such as stockings that eliminates the various drawbacks mentioned above by repeating the sipping process 11 times.

Dyeing of knit products such as stockings, which is the present invention, involves placing an object to be dyed in a dye tank having a drainage water of 1", injecting a dye solution into the dye tank, and immersing the object in the dye solution. After that, drain the dye solution, press the dyed object described in 1- above against the bar side,
By repeatedly squeezing out the dye liquid contained in the dyed object and draining it, the dyed object can be immersed in the dye liquid in an almost static state or forced to drain. It is characterized by the fact that it is made to do so.

Embodiments of the present invention will now be explained with reference to the accompanying drawings. Figure 1 shows a state in which an object to be dyed is stored in a dyeing tank, the drain 11 is closed, a dye solution is injected, and the object to be dyed is immersed. The lid will be closed immediately.

In the same figure, A is a dyeing tank that is open on the two sides, has a bottom plate 1 made of a perforated plate on the inner side, and has a drain port 2 in the center of the bottom; The bottom lid opens and closes, 4 is an air cylinder that moves the bottom lid 6, and 5 is the stain tank A.

Pressurize the dye liquid etc. from the 1st side of the tank with the pump 8, heat the 10th dye liquid to a predetermined temperature in the heat exchanger 10 in the auxiliary tank 9, and dye (111, 1 part position of IA). A dye solution circulating device 11 for communicating the dye solution is an overflow bypass pipe connected to the auxiliary tank 9 and the suction side of the pump 8.

Reference numeral 16 denotes an extension bag into which the dyed material 2, such as stockings, is dyed 111J, and this bag is highly permeable to liquids.

The embodiment of the present invention is constructed as follows.

Next, its effect will be explained.

As shown in FIG. 1, the required number of bags 16 of the dyed material are put into the dyeing tank A.

The procedure for inserting these bags is as simple as stacking them in order, and no skill is required.

Next, the valve 17 is opened and the dye liquid is injected into the dyeing tank A1'J from the injection pipe 15, and the lid 5 is tightly tightened.

At this time, as shown in FIG. 2, the lid is fixed to the staining tank A at the stopper 1B.

When the dye liquid is sufficiently injected into the dyeing tank A, the object to be dyed in the bag 16 is immersed in the dye liquid, and then the valve 15 is closed and the injection of the dye liquid is stopped.

Next, when the dye solution is immersed for 1°, the air cylinder 4 is activated to evacuate the bottom cover 6 and open the drain port 2, as shown in FIG.
f: Open and drain the dye solution, then operate the machine link 7 to move the presser plate 6 downward and press the bag 16 of the dyed material onto the bottom plate 1. Here, the dyed material is written on the bottom plate 1. The dye liquid is squeezed out and the water is forcibly drained by pressing between the presser plate 6 and the presser plate 6.

This forcible squeezing of the dyed object is preferably carried out under pressure that does not impair the quality of the dyed object.

When 1 uJ of water is finished, the air cylinder 4 is operated in reverse to raise the bottom cover 6 to - to close the drain 1''2, and the air cylinder 7 is also operated in reverse to raise the holding plate 6 to 1.+f1. After that, the valve 17 is opened and the dye liquor is again injected into the dyeing tank A through the pipes of the dye liquor circulating device C.

Dyeing is carried out by repeating the above-mentioned immersion and water soaking treatments for 11°Q.

Here, only the dyeing work-L step has been explained, but when actually carrying out the dyeing process, 1st S L e p Scouring work 28 t, e P Addition of auxiliary agent 3rd S t G P Dyeing ( 4th step: heating the dyeing solution 5th step: dyeing process t5 Step washing with water 7th step Fixing process:, '('', 8S l, t・1 (softening process) 9th Ste.
p The process of draining the water and taking out the dyed material is generally performed, and the final dyed material (dyed material becomes a dyed material) is dyed 1:+5 from A at 11y, when the dyed material is squeezed out sufficiently. It is lighter and therefore the work of taking out the dyed product is very easy.In the example, the bottom of the dyeing tank is explained with a mechanism that can be opened and closed, but the drainage to the dyeing tank 1
-12 to an appropriate size and made it so that it could not withstand the dyeing liquid leaking, and when injecting the dyeing liquid, the object to be dyed was immersed, and when the dyeing liquid was stopped, the water drained naturally, and the dyed object was held down. Even if the water is forcibly removed by attaching the water, the gist of the present invention will not be changed.

1. According to the present invention, the following effects are obtained.
4゜(1
) The process of immersing the dyed object in the dye solution and draining the water can be repeated in a nearly stationary state, which prevents the dyed object from becoming tangled, entangled, scratched, or scratched. Therefore, the extra work of removing entangled metal is eliminated, and not only can a high-quality product be obtained, but productivity can also be improved.

(2) Since water can be forcibly drained by pressing the dyed object, draining time can be shortened and production efficiency can be improved.

(3) Because it is possible to narrow down the components, the dyed material becomes lighter after the color processing is completed, and therefore dyeing 4:Hll
The work of taking out the dyed material by +1y becomes easier, and the burden of work can be reduced.

(4) Inserting the object to be dyed into the dyeing tank, all you have to do is place the object in an appropriate manner, so there is no need to push the object in evenly as with conventional liquid jet dyeing machines, and it is not necessary to push the dyed object evenly into the dyeing tank. It is not necessary and insertion can be done in a short time.
