れる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aggregate of flame-resistant fibers or carbon fibers to which a specific amount of sodium dioctylsuccinate sulfonate is attached. It is known that flame-resistant fibers or carbon fibers are used as packing materials by taking advantage of their chemical resistance and sliding properties. When such fibrous materials are used as packing materials, spun yarns, woven fabrics, nonwoven fabrics, etc. made of these fibrous materials are impregnated with polyfluoroethylene such as polytetrafluoroethylene (PTFE). In addition, when composing spun yarns of the above-mentioned fiber materials into braided cords, etc., impregnating them with PTFE in advance allows braiding to be easily performed without yarn breakage, etc., and has excellent denseness and sliding properties. product is obtained.

発明に至つたものである。 However, impregnation with PTFE is usually carried out using its aqueous emulsion, but flame-resistant fibers or carbon fibers have poor affinity with aqueous emulsions, and the spun yarns of these fibers have surface treatment agents attached to them. Therefore, it was difficult to sufficiently penetrate the PTFE emulsion into the inside of these fiber aggregates. The present inventors investigated a technique for effectively impregnating PTFE with a PTFE emulsion by sufficiently permeating such fiber materials. As a result, the present inventors found that a flame-retardant material with dioctyl succinate sodium sulfonate of the following formula (1) attached in advance was developed. Infiltrating the fiber or carbon fiber aggregate with PTFE emulsion,
The inventors have discovered that by drying the fibers, the flame-resistant fibers or carbon fiber aggregates can be effectively impregnated with PTFE, leading to the present invention.

It is obtained by subjecting organic fibers such as acrylonitrile fibers, rayon fibers, pitch fibers, and phenolic fibers to flame-resistant treatment or subsequent carbonization treatment using known methods, and is defined as flame-resistant fibers and carbon fibers in the commonly used sense. It is. In addition, the aggregate of these fibers includes a strand of these fibers, a nonwoven fabric, a spun yarn, a woven fabric, a braid, and the like. In particular, the spun yarn of flame-resistant fiber obtained by oxidizing acrylonitrile fiber has high strength, and the thick yarn spun from the tow of this flame-resistant acrylonitrile fiber has a high strength.
Good impregnation of PTFE. This PTFE-impregnated spun yarn has extremely excellent processability into fabrics and braids, and at the same time exhibits excellent sealing and sliding properties when used as a packing material.

Make it adhere. If the amount of adhesion is less than 0.1%, there will be no effect, and if it is more than 1%, the impregnated PTFE will easily fall off. As for the method of attachment, the same method used for applying surfactants to fibers is usually adopted. That is, immersion methods, spray methods, roller contact methods, etc. are examples. Prior to this adhesion treatment, if the surface treatment agent such as a surfactant (spinning oil) applied to the fiber material is removed by washing with water or organic solvent, more favorable results will be obtained. The amount of adhesion is adjusted by conventional methods such as adjusting the solution concentration and squeezing rate. After adhesion, it is dried at 80-150°C.
