This relates to a method of flame-retardant treatment using fibers and, if necessary, carbonization treatment.

炭素化始期して、炭素繊維を得ることは知られている。Conventionally, acrylic fibers are flame-resistant treated under tension at 200-300℃ in air to make them flame-resistant, or these flame-resistant fibers are then carbonized using a tensile strength specialist in an inert gas atmosphere at 500℃ or higher. It is known that carbon fibers can be obtained by

った。In addition, the carbon fiber obtained in the above manner has excellent specific strength and specific elasticity, so it is used in sports and leisure goods, automobiles, high-speed drive bodies, and even in the aviation and space fields, and demand is increasing. I'm here. However, as demand increases, depending on the application, the conventional tensile strength is 300 to 350K.
The fiber with a culm density of 11 g/l is unsatisfactory, and there is now a demand for a carbon fiber with a higher strength than this.

の処理工程と次の処理工程との間において行なわれる。Generally, in the production of acrinitrile fibers, treatments such as stretching, drying, and relaxation are performed after the solvent is removed during spinning. The ammonium salt adhesion treatment of the present invention is carried out at any stage from after solvent removal in the acrylonitrile fiber manufacturing process until the fiber manufacturing is completed or after the fiber manufacturing is completed. That is, it is carried out in at least one of the above-mentioned processing steps or between one processing step and the next processing step.

維間に十分侵入させるためには、好ましくは浴温20〜
70℃で1〜5分浸漬を行う。In the ammonium salt attachment treatment, a solution prepared by dissolving or dispersing one or more predetermined ammonium salts in water for at least 2 seconds is attached to the fibers. The deposition process is usually carried out by spraying the liquid onto the fibers or by immersing the fiber bundles in a bath of the liquid. In order to sufficiently infiltrate the ammonium salt between the single fibers of the fiber bundle, the bath temperature is preferably 20~20°C.
Immersion is performed at 70°C for 1 to 5 minutes.

増すなどのため、得られる炭素繊組の強度が低くなる。If the temperature is higher than 70°C, the compound tends to aggregate in water, resulting in formation of adhesion spots and increased permeability into the fibers, resulting in a decrease in the strength of the resulting carbon fiber assembly.

い。pH4より高くなると、該化合物が凝集し易くなり
、膠着を増加さける傾向となるので好ましくない。On the other hand, if the temperature is lower than 20°C, it is not preferable because it is difficult to dissolve and disperse in water and the dispersed particles are too large, resulting in adhesion spots and sticking. The concentration of the liquid is usually 1 to 20 g/l. In addition, the pH condition of the ammonium salt-containing liquid affects product performance, and a pH of 4 or less is preferred in order to obtain higher quality flame-resistant fibers and carbon fibers. If the pH is higher than 4, the compound tends to aggregate, which tends to increase adhesion, which is not preferable.

素繊維を製造するのに良い。The pH may be any value as long as it is 4 or less, but it is usually 1 or more, preferably 2 to 3.5. Further, the pH is preferably adjusted using an acid or caustic soda having an anion of the same type as X of the compound. The amount of adhesion is 0.01 to 0 based on the fiber weight.
.. 5% is good. If the adhesion amount is less than 0.01%, a sufficient anti-sticking effect cannot be obtained, and if it exceeds 0.5%, carbides are likely to be formed on the fiber surface during carbonization treatment, and the strength of the carbon fiber is reduced accordingly. When the amount of adhesion is 0.3% or less, the ammonium salt permeates into the interior of the fibers to a small extent, which is particularly suitable for producing high-strength carbon fibers.

This fiber is suitable for obtaining high-strength carbon fibers. Arylonitrile fibers that have been heat-treated at 200 to 300°C with a temperature increase rate of 10°C/sec or less over 200°C may be once rolled up and then subjected to a flame-retardant treatment process.

である。The ammonium salt-attached acrylonitrile fibers are subjected to flame-retardant treatment after or without heat treatment as described above. The flameproofing treatment is performed by a conventionally known method. That is, flameproofing treatment is carried out in an oxidizing atmosphere, for example in air, at a temperature of 200 to 300°C, preferably 250 to 300°C, for 0.1 to 15 hours. In order to obtain high strength carbon fiber, 200m
In order to obtain carbon fibers with even higher strength, it is preferable to carry out the process under a tension of 10 to 100 mg/denier. The flame-retardant treatment reduces the specific gravity of the fiber to 1.
