としてバイエル社製のレゾリンブルーＦＢＬ。Examples of the disperse dye used in the dyeing method of the present invention include disperse dyes commonly used for dyeing polyester fibers. There are two types of disperse dyes: low-energy types with relatively small molecular weights and high-energy types with large molecular weights.Low-energy type disperse dyes can be dyed in deep colors at relatively low temperatures, while high-energy type disperse dyes are generally Therefore, it is necessary to dye at a higher temperature than low-energy type disperse dyes. And Resolin Blue FBL manufactured by Bayer is a low energy type disperse dye.

るので好ましい。Examples include carriers such as aromatic ethers, 1-minute aromatic esters, chlorbenzenes, etc., but orthophenylphenol carriers are particularly preferred because they enable dyeing in deep colors at lower temperatures.
分散染料は、ＰＥＥＫ繊維に対する重量比率のｏｕｒ％

ない。That is, when dyeing a light color, the owf may be about 1 to 3%, when dyeing a medium color, the owf may be about 4 to 8%, and when dyeing a dark color, the owf may be about 8 to 15%. On the other hand, the carrier concentration is usually sufficient at a concentration of 3 to 6 g per 2 dye solutions, and is not particularly limited to this range.

When dyeing 6Jf fibers, it is preferable to use a high-pressure, high-temperature liquid jet dyeing machine because high dyeing efficiency can be obtained and uniform dyeing can be achieved.

することができ、その濃度を下げれば淡染化できる。As described above, when fibers are dyed with PEE using a hot water dyeing solution of 90'C or higher containing a carrier and a disperse dye, the fibers can be easily dyed with PEE in the same way as conventional dyeing of polyester fibers with disperse dyes. This makes it possible to obtain PEE fibers dyed with disperse dyes, which were previously unobtainable. That is, by increasing the owf of the disperse dye within the above range, PEEK fibers can be dyed deeply.
As in the case of conventional dyeing of polyester fibers, it is possible to achieve deep dyeing quickly by increasing the solution temperature, and conversely, by lowering the owf of the disperse dye and the solution temperature, light dyeing can be achieved. Further, by increasing the concentration of the carrier, deep dyeing can be achieved, and by lowering the concentration, light dyeing can be achieved.

与えられないためと考えられる。However, if no carrier is added to the dyeing solution, polyester fibers can be dyed, but PEEK fibers are hardly dyed. Further, even if a carrier is added, if the temperature of the dyeing solution is lower than 90° C., fibers cannot be dyed satisfactorily with PEE. In the case of polyester fibers, it is T where molecular motion of the amorphous part of polyester begins.
g'C is about 70℃ and 90℃ higher than Tg'C
When dyeing is carried out at temperatures above 120 to 130 degrees Celsius (120 to 130 degrees Celsius), disperse dyes easily diffuse thermally into the interior of polyester fibers where molecular motion becomes active and dye the amorphous parts. However, in the case of PE [fiber, Tg
``C is about 145℃, and even if you use the currently known high-pressure dyeing machine that can obtain the highest temperature, the dyeing temperature is about 140℃, which is lower than Tg'C, so do not use a carrier. This is thought to be due to the fact that even with the aid of a carrier, if the dyeing temperature is lower than 90°C, the disperse dye will not be given enough energy to thermally diffuse into the fiber. .

The fact that ER fibers can be dyed sufficiently means that the dyeing machines conventionally used for dyeing polyester fibers can be used as is.
It is extremely advantageous industrially.
