Description

[Detailed Description of the Invention] The present invention relates to a method for improving the fastness of dyed synthetic fiber products, and in particular, to significantly improve the fastness to rubbing and washing of dyed synthetic fiber products treated with finishing agents. The purpose is to provide a processing method that will

Regarding VC for synthetic fiber products (dyed products) in general.

Texture - Physical Properties 1 Depending on functionality and other purposes, various finishing treatments are applied, such as flexible finishing, hard finishing, water repellency, water repellency, knee-shrinking, wrinkle-proofing, and knee-webbing prevention finishing. In this case, the fastness of dyed ah products, such as rubbing fastness and washing fastness, will be significantly reduced (1 to 3 grades lower) if such various finishing treatments are applied.
That's what it means. Due to this decrease in fastness, −Km A
kW Product (7) Since the commercial value is significantly impaired, the current situation is to suppress this decrease by selecting the type of finishing agent and processing method, but this limits the finishing processing and reduces the fastness. There was a demand for the development of a new +1- process that would prevent deterioration.

For this reason, resin and chemical manufacturers and those involved in finishing are trying to develop finishing agents and processing methods that reduce fastness, but these efforts are limited to dyeing, weaving, and finishing. The color fastness of the product decreased less than that of the finishing agent (the purpose was to maintain it at the same level as possible, and it did not go beyond the original fastness of the dye).

On the other hand, there are cases in which dyes themselves have good level dyeing properties but are hesitant to use them due to poor fastness, and it is desired to develop an efficient fastness method for such dyes. .

The inventors of the present invention are: power) Kashiru Kinan, HoH hat, two swords, and one sword.
As a result of intensive research, we have developed a method to significantly improve the fastness of dyed synthetic fiber products treated with finishing agents.
We have arrived at the present invention. In other words, the present invention uses dyed synthetic fiber products that have been treated with a finishing agent in a gas Ii of 0.01-10.
This invention relates to a method for making dyed synthetic fiber products durable, characterized by treatment with low-temperature plasma of inorganic gas.

According to the present invention, it is possible not only to prevent a decrease in fastness caused by finishing processing of dyeing compound 1 and TJp products, but also to improve the fastness compared to before finishing processing (I This has the effect of improving the IW by grade 4, thereby eliminating restrictions on the types of finishing agents and processing methods, allowing a variety of 7:C finishing treatments to be applied to dyed and recycled products, and improving single-sided textile products. The product price of 41C1 will be significantly increased.

Next, a detailed explanation of the present invention'f/-).

The dyed synthetic fiber products targeted by this book are polyester fibers, nylon fibers, agrillyl fibers, polypropylene fibers, acetate fibers, vinylon fibers, or blends containing at least 50% of these by weight. Condition 1
It includes all knitted fabrics, non-woven fabrics, and thread-like fabrics. There are no particular restrictions on the dye used for dyeing, and commonly available commercially available or developed dyes may be used as appropriate.

The finishing agents used for finishing include softening agents (silicone threads,) 1-id a-bon threads, etc. J, Il!
#! Finishing agents (melamine thread, urethane thread - vinyl acetate thread, polyester type, etc.), water-repellent/oil-repellent agent (silicone thread, fluorine thread, etc.) - μj shrinking/clearing agent (urinated thread, Examples include glyoxal yarn, etc. The processing conditions for finishing may be carried out according to conventionally known methods, and the method itself is not limited to 1.%.

In the present invention, dyed synthetic fiber products that have been treated with the 1F finishing agent are subjected to low-temperature plasma treatment. Opposite chest W, internal chest with poles,
Using an extremely low-temperature plasma generator, set the target dyed synthetic fiber product on the top of the earth side of the device.
Both sides of the dyed synthetic fiber product are treated with low-temperature plasma generated by generating a glow tortoise force of, for example, 400 volts or more between both electrodes while circulating an inorganic gas under the mFlz. This method is used.

The inorganic gas used here is helium.

Neon, argon, nitrogen, oxygen, grass, suboxide, −
Examples include nitrogen oxide, nitrogen dioxide, carbon oxide, carbon dioxide, anionized bromine, sulfurous acid gas, and sulfide, which may be used alone or in combination of two or more. In the present invention, it is preferable to use oxygen gas or a gas containing at least an IO capacity ratio of oxygen gas as the inorganic gas.

The pressure of the gas atmosphere inside the low temperature plasma generator is 0.
．． A range of 0l-10) is desirable, and under such gas pressure a frequency of 10KHz = 1001 is applied between the counter electrodes.
10W to 100KW at a picture frequency of VlHz
Stable glow discharge can be produced by applying electric power such as this. In addition to the above-mentioned high frequency, the discharge frequency band includes low frequencies.

Microwaves, @flow, etc. can be used.

In addition to the internal cold electrode type described above, the low-temperature plasma generator may be an external single-pole type, or may be a coil type, capacitively coupled or diductively coupled. There are no particular restrictions on the shape of the city or pole.
The input side electrode and the ground side electrode may have the same shape or different shapes, and they can be in various shapes such as a flat plate, a ring shape, a rod shape, or a cylinder shape. Furthermore, the inner wall of the gold layer of the device may be The electrode may be of a grounded type.

In the sense of imparting efficient treatment effects with short-time low-temperature plasma treatment, it is desirable to use a device with one internal electrode, and in this case, the distance between the electrodes is preferably 1 to 30c1n.
It is recommended to set it to ~1Ocrn. Regarding electrode materials, metals such as Kaito Tetsu, stainless steel, and aluminum are used, but for the input side electrodes, in order to maintain stable radiation, enamel coat, glass coat, ceramic coat, etc. are used. It is preferable to provide an insulating coating with a pressure of 1 rllt, and it is desirable to have a voltage resistance of 1000 volts/gas or more when DC is applied.
