゛浸染染色後の工程として染色φ牢度向上のため還元洗
浄工程が取り入れられている。In general, if polyester textiles are simply dyed by dyeing, especially in the case of deep color dyeing, some of the dye adheres to the surface of the polyester A/fiber, resulting in poor dye fastness. IIIu prison degree, promotion IIl prison degree, etc. are controlled and are usually low values. For this reason, general crystals incorporate a reduction washing process as a process after dyeing to improve the durability of the dyeing process.

のである。A common method is to use a non-ionic agent i in combination and treat at 70C to 90C for 10 to 40 minutes, followed by washing with water.
Adopting this reduction washing process improves the color fastness of dyed polyester fibers, but on the other hand, it naturally increases costs due to the use of water and heat. There will also be a need for processing etc.
This development was carried out in view of the current situation, and the purpose is to obtain the same color fastness improvement effect as conventional reduction cleaning without using water or chemicals like conventional methods. It is.

牢度の向上を行うことができる。In order to achieve this object, the present invention has the following configuration. That is, the present invention is a 49-process step A/CSM method in which a textile product is subjected to dyeing and then subjected to reduction cleaning, and then the textile product is subjected to low-temperature plasma treatment with an oxidizing gas or a reducing gas. This is a method for improving the color fastness of textile products. According to the present invention, unlike conventional reduction cleaning, chemicals, water, heat, etc. are not used, and there is no need for wastewater treatment as a countermeasure for book separation. It is possible to improve the color fastness of textile products.

ことにより染色堅牢度の向上を行う。The method of the present invention will be described in detail below.In the method of the present invention, first, polyester μ fibers are dyed by a conventional dip dyeing method and then dried without reduction washing. Dyeing is done using disperse dyes or cationic dyes, which are dyes for polyester, under normal conditions such as 120c to 150c for 10 minutes to 1 hour.
Stain for about 20 minutes. In the conventional method, reduction cleaning is performed after this, but in the method of the present invention, this is not performed, but water washing and drying are performed. After drying 1. In the present invention, the color fastness is improved by subjecting scissors delicate products to low-temperature plasma treatment with saponifiable gas or reducing gas instead of the conventional reduction cleaning process.

る。The low-temperature plasma treatment referred to in the present invention means that the dyed polyester fiber material to be treated is treated in a gas reduced pressure system, that is, at 0.1
It means to be placed in an atmosphere obtained by performing glow discharge while maintaining the temperature at ~10 Torr. Gases include acid 31100% or oxygen and other gases such as nitrogen and argon. An oxidizing gas such as a mixture of helium, carbon dioxide, water vapor, etc., or a mixture of water, hydrogen, and other gases such as diluted food, argon, chlorine, N carbonate, etc.
Use a reducing gas such as a gas mixture with gas, water vapor, etc.

低温プラズマを発生させるには上記気体を０．１〜１０
　Ｔｏｒｒの減圧下でこれに高周波の照射を行う。To generate low-temperature plasma, the above gas should be mixed at a concentration of 0.1 to 10
This is irradiated with high frequency under a reduced pressure of Torr.

マの発生が不安定になりやすいこと′、雰囲気の温度が
高くなりすぎることなどによるものである。In this way, low-temperature plasma is generated and plasma processing becomes possible. The reason for setting the processing pressure to 0.1 to 10 Torr is that below 0.IT Torr, the gas concentration is too low and processing time is required, and the cost of maintaining the vacuum level is high, which is economically disadvantageous. This is due to the fact that the generation of low-temperature plasma tends to become unstable' and the temperature of the atmosphere becomes too high.

グロー放電させる高周波電源は長波長から短波長まで相
当広い範囲で使用できるが、操業安定性。High-frequency power sources that generate glow discharge can be used over a fairly wide range of wavelengths, from long wavelengths to short wavelengths, but operational stability is limited.

望ましくは２０〜１２０抄である。The processing time depends on the slant of the polyester textile, the type of dye,
Although it varies depending on the amount of dye stool, it is usually 5 to 300 seconds, more preferably 20 to 120 seconds.

、これにより染色堅牢度が向上する。High-frequency energy μ is applied to the above-mentioned oxidizing gases and reducing gases in a reduced pressure system.
When gas is applied, oxidizing or reducing gases are activated and become highly reactive, so if dyed 49-ester fibers are placed in that atmosphere, the surface of the polyester fibers will be dyed. The dye present in the dye is oxidized or reduced, which improves color fastness.

繊維品の染色φ牢度の向上を行うことができる。The present invention has the above configuration. According to the present invention, chemicals, water, heat, etc., as in conventional reduction cleaning are not used, and
Therefore, wastewater treatment is also necessary as a countermeasure for this purpose.
Therefore, it is possible to improve the dyeing strength of polyester textiles at extremely low cost.
