本発明は耐熱性繊維に関する。更に詳しくは耐熱性樹脂
であるポリエーテルイミドからなる工業用繊維に関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to heat-resistant fibers. More specifically, the present invention relates to industrial fibers made of polyetherimide, which is a heat-resistant resin.

れている。Polyetherimide resin was marketed by General Electric Company in 1982 under the trademark Ultem and continues to this day. Among them, the polyetherimide represented by formula (I) is called by the grade name Ultem 1000. Ultem 1000 is a heat-resistant resin with a glass transition temperature of 216° C. and is widely used in the injection molding field.

留まっている。However, there are very few documents showing the application of polyetherimide resin to fibers, and the only one is JP-A No. 59-22726.
A polyethel imide fiber is disclosed in the issue, and the fiber of the polyeter infimide shown in (I) is described. However, in this prior example, the stretching ratio after melt spinning cannot be increased, and the tensile strength remains at an extremely low level of 1.55 L/d or less.
〔発明が解決しようとしている問題点〕前記したように
従来のポリエーテルイミド繊維は引張強度が低いことが
問題である。[Problems to be Solved by the Invention] As mentioned above, the problem with conventional polyetherimide fibers is that they have low tensile strength.

維な提供することである。The present inventors have found that the teretherimide fiber having the structure of formula (I) has slightly poor oil resistance, and when heated with a finishing oil attached, the drawability of the undrawn yarn decreases. K. It was found that the drawing ratio could not be increased, and therefore only a drawn yarn with low tensile strength could be obtained, and even in the case of drawn yarn obtained by some means, the strength would further decrease due to oil adhesion. However, if a finishing oil is not applied, the unwinding properties of the yarn wound into a package will be extremely poor, leading to frequent troubles in subsequent processes. SUMMARY OF THE INVENTION An object of the present invention is to provide teretherimide fibers that have high tensile strength and excellent unwinding properties even when no oiling agent is applied.

した。As a result of extensive studies, the present inventors found that the finish could be achieved by using an air entanglement method (incraser) between the filaments before winding up the spun multifilament undrawn yarn and after drawing it, instead of applying an oil agent. The present invention was achieved by discovering that adding confounding to the above is effective in solving the problem.
