ットやシートなどに使用することも検討されている。Polyetherimide fibers are increasingly being used to create composite materials by melting the polyetherimide fibers after laminating them. In addition, since this fiber has excellent flame retardant properties, its use in flame retardant mats, sheets, etc. has been considered in recent years.

ならないと考えられていた。However, as can be seen from its molecular structure, polyetherimide fiber does not have a dyeing seat, so it cannot be dyed with ionic dyes such as acid dyes and cationic dyes, and its glass transition temperature is high (211°C). As a counter-effect, it was believed that dyeing with conventional disperse dyes had to be carried out at extremely high temperatures.

ていた。(Problem to be solved by the invention) However, when used in flame-retardant mats and sheets, which have been in increasing demand in recent years, it is necessary to color them to improve interior appearance, and also in industrial applications such as protective clothing. There was a demand for colored polyetherimide fibers to improve fashionability, and the development of dyed polyetherimide fibers was desired.

色しうろことを見出し本発明に到達した。(Means for Solving the Problems) As a result of repeated research to achieve the above object, the present inventors have found that, contrary to the conventional estimation, dispersion is possible even at a dyeing temperature considerably lower than the glass transition temperature of polyetherimide. The present invention was achieved by discovering that polyetherimide fibers can be easily dyed using dyes.

特徴とするポリエーテルイミド繊維の染色方法である。That is, the present invention provides a dyed polyetherimide fiber characterized in that the main repeating unit is made of polyetherimide represented by the following formula and is dyed with a disperse dye, and a polyetherimide fiber that is dyed with a disperse dye. This is a method for dyeing polyetherimide fibers, which is characterized by dyeing at a dyeing temperature of 135°C or higher.

For this purpose, a low-energy type with a relatively small molecular weight and a high-energy type with a large molecular weight are required.The former are Resolin Blue FBL (manufactured by Bayer) and Sumikalon Blue E-FBL (manufactured by Sumitomo Chemical), and the latter is Examples include Sumikalon Navy Blue-S-2GL, Sumikalon Blue-34G, and Sumikalon Red 5-BL (all manufactured by Sumitomo Chemical).

考えると、ポリエーテルイミド繊維が、そのガラス転移
点よりもはるかに低温で染色できることは驚くべきこと
である。In the present invention, the aqueous dispersion of the disperse dye described above is used as a dyeing solution, and the dyeing temperature is set to the glass transition temperature of polyetherimide (2
17°C), but above 135°C,
Preferably, it is necessary to carry out the dyeing at a temperature of 140'C or higher. Conventionally, when dyeing ordinary polyester fibers,
It is surprising that polyetherimide fibers can be dyed at temperatures much lower than their glass transition temperature, considering that they can only be dyed at temperatures much higher than their glass transition temperature (70°C) (120-130°C). It is the right thing to do.

断面内にほぼ均一に染色できるのでより好ましい。However, if the dyeing temperature is lower than 135°C, hardly any dyeing will occur, which is not preferable. On the other hand, there is no need to particularly limit the dyeing temperature, but it may be selected appropriately from the viewpoint of energy cost, increased cost of dyeing equipment, thermal stability of the disperse dye used, etc. In this case, it is more preferable to set the temperature to 140° C. or higher, since this allows dyeing to be done almost uniformly within the fiber cross section.

非常に硬くなるうえに脆くなるので適用できない。In the present invention, adding a dispersion and leveling agent to the dye solution to improve the dispersibility of the dye and adding acetic acid to prevent the decomposition of the disperse dye are different from the conventional dyeing method for polyester fibers. The same applies. However, the method of lowering the dyeing temperature or using a carrier in combination to dye the dyed product to a deeper color cannot be applied because the dyed polyetherimide fiber becomes extremely hard and brittle.

る。(Function) As mentioned above, it was thought that it would be difficult to dye polyetherimide fibers with disperse dyes due to their high glass transition temperature (217°C), but as a result of the studies conducted by the present inventors,
Dyeing temperature 135℃, much lower than its glass transition temperature
As mentioned above, it has been found that dyeing with disperse dyes is effective preferably at a temperature of 140° C. or higher. The reason why polyetherimide fibers can be dyed at much lower temperatures than their glass transition temperature is still unclear, but one reason may be that the water in the dye liquor plasticizes polyetherimide and lowers its glass transition temperature. There is a possibility that In any case, since it is a disperse dye that is not a reactive dye and can be dyed at a temperature much lower than the glass transition temperature of polyetherimide, jq
The dyed polyetherimide fiber has high elongation,
Properties such as heat resistance, chemical resistance, and flame resistance do not deteriorate.

効果が得られる。(Effects of the Invention) According to the present invention, polyetherimide fibers, which were conventionally thought to be completely undyable, can be easily dyed by high-temperature, high-pressure dyeing at 135° C. or higher. Therefore, there is a possibility that the high-temperature, high-pressure dyeing machines used for dyeing polyester fibers can be used. Furthermore, the dyed polyetherimide fibers have mechanical properties, heat resistance, chemical resistance, flame retardancy, and other properties comparable to those before dyeing, and the dyeing has good washing fastness and light resistance. An excellent effect can be obtained.
