原糸油剤である。[Prior Art] A typical example of a raw material oil agent for producing an inorganic Hh fiber type is a raw material oil agent for producing carbon fibers.
It is shown in Japanese Patent Publication No. 53-10175 and Japanese Patent Publication No. 80-43446. The contents include troubles when treating raw yarn (precursor) for manufacturing carbon wire M to be infusible or flame-resistant (fusion between single yarns, fluffing due to mechanical defects on the fiber surface, yarn breakage) This is a raw material oil for producing carbon fibers that eliminates this problem and produces carbon fibers with a certain level of quality and performance with good productivity.

が強度劣化し実用上問題がある。Such a raw material oil for producing carbon am is a water-based treatment agent, and when applied to raw fiber for producing inorganic fibers based on the sol-gel method, the strength of the raw fiber itself deteriorates because water is involved in the chemical reaction state of the raw fiber. There are practical problems.

In the manufacturing process, it prevents adhesion between single fibers, fuzz, thread breakage, yarn unraveling (disturbance of bundle of single fibers), etc., and prevents the binding effect of multiple single fibers and moisture adsorption on the fiber surface. We have conducted extensive research and discovered an oil agent to be applied to yarn for producing inorganic fibers (hereinafter referred to as yarn oil agent or process oil agent) that has the effect of suppressing the gelation reaction.

The present invention can be commonly applied to these methods.

無機質繊維製造用原糸油剤を提供するものである。[Means for Solving the Problems] The present invention was made to solve the above-mentioned problems, and consists of liquid paraffin having an average carbon number of 18 or more, solid paraffin having an average carbon number in the range of 20 to 50, and a liquid paraffin having an average carbon number of 18 or more. The object of the present invention is to provide a raw oil agent for producing inorganic fibers, which is obtained by mixing the following.

ール系物質と接触すると急激に高分子化又は溶解し強度
を損なったり融着や繊維欠陥が生起することを避けられ
ない。このため非水系及び非アルコール系の油剤を用い
ることが望まれる。When raw fibers for producing inorganic fibers based on the sol-gel method come into contact with water or alcohol-based substances, they rapidly polymerize or dissolve, which inevitably leads to loss of strength, fusion, and fiber defects. For this reason, it is desirable to use nonaqueous and nonalcoholic oils.

ラブル防止に顕著な効果を示す。The main components of the oil agent in the present invention are liquid paraffin and/or solid paraffin, which are non-aqueous and non-alcoholic substances, and have excellent performance as a raw oil agent for producing inorganic fibers, especially as a process oil agent for inorganic fibers based on the sol-gel method. It has a remarkable effect on preventing troubles caused by water and alcohol-based oils.

素数が１８より小さくなると流動パラフィン中に揮発し
易い液体（分子量の小さいもの）が混入しており、これ
が単繊維間に接着を起こし易く、この場合油剤の使用は
困難となる。When the average carbon number of liquid paraffin, which is a component of the oil agent of the present invention, is less than 18, volatile liquid (low molecular weight) is mixed into the liquid paraffin, and this tends to cause adhesion between single fibers. In this case, it is difficult to use oil.

度劣化が避けられずこの場合油剤の使用は困難となる。Furthermore, if the average carbon number of the solid paraffin, which is a component of the oil agent of the present invention, is less than 20, it will not solidify at room temperature and the fibers will have poor cohesiveness and fluff will easily occur, making it difficult to unwind the fibers. Further, if the average carbon number exceeds 50, unless the amount of oil adhering to the yarn is considerably reduced, deterioration of the strength of the yarn due to heat generation during sintering cannot be avoided, making it difficult to use oil in this case.

The mixing ratio (A)/(B) is 0/100 to 10010. The preferred mixing ratio is slightly different depending on whether the spinning process is a winding method or a composting method, but in the case of the winding method, a mixing ratio of 10010 is unfavorable in terms of cohesiveness, fuzz, and retentivity.

そのために糸の強度劣化をまねく。The amount of liquid paraffin and/or solid paraffin of the present invention attached to the raw thread (raw thread + attached amount = 100) is 3 to 3.
It is preferably 30%, and if it is less than 3%, the desired performance cannot be obtained. Moreover, if it exceeds 30%, it becomes difficult to unwind the yarn, and furthermore, it is easy to catch fire during firing, which not only hinders the firing but also causes a deterioration in the strength of the yarn.

However, the physical properties of the fiber after sintering are unavoidable.The raw material oil for producing inorganic male fibers of the present invention is non-aqueous and non-alcoholic. Such a yarn oil agent has excellent solution stability and uniformity of adhesion to the yarn, and is characterized in that it prevents the occurrence of adhesion between single fibers after the treatment of adhering to the yarn and after the sintering treatment. In addition, the liquid paraffin of the present invention has excellent lubricity, and the solid paraffin has even better cohesiveness, and since liquid paraffin and solid paraffin are not soluble in each other, they act independently and each has the effect of preserving the yarn. This is considered to occur.

せると共に焼成して高強度の石英ガラスｍ！ａを得る。In the figure, numeral 1 indicates an inorganic fiber, such as a quartz glass fiber, immediately after spinning. In the case of silica glass fiber produced by the sol-gel direct spinning method, a sol solution is created by hydrolyzing and polymerizing metal alcoholates (ethyl silicate, methyl silicate, etc.) using an acid or alkali as a catalyst, and a sol solution with an appropriate viscosity (10 to 1,0
00poise), the sol solution is extruded from the nozzle and spun to produce gel fibers. This corresponds to the above-mentioned quartz glass material immediately after spinning. Since the tensile strength of the fibers in this state is low, they are heated to a temperature of about 700 to 1300°C for several minutes to several hours to volatilize the residual carbon and fired to create high-strength quartz glass. get a.
