The present invention relates to a method for preventing friction scum on polyester synthetic fibers whose surface has been treated with an oil agent containing an epoxy compound. In the process of turning synthetic fibers into products such as twisted yarn, knitting machines, and looms, and turning them into twisted cords, woven fabrics, and knitted fabrics, the threads pass through various guides under constant tension to regulate their movement. A process is required. In particular, treatment with epoxy compounds at the fiber manufacturing stage is a commonly used technique to make tire cords more easily adhered to tire cords. The base textile oil and epoxy compound are used in combination, and it has been put into practical use as a special textile treatment agent. However, in order for the surface of polyester fibers treated with an oil agent containing an epoxy compound to become easily adhesive, the epoxy compound on the fibers needs to grow into a highly polymerized film.
For this reason, there are many scum-like substances mixed with adhesive substances and oligomers on the fiber surface, and when such yarns are twisted in a subsequent process, scum-like substances are formed on the guides present in the yarn guide. The accumulation becomes noticeable and impairs productivity. Furthermore, in recent years, processing speed has increased to improve productivity, and the increase in scum is becoming a problem. For example, when manufacturing thick woven products using a rapier weaving machine, if the weft feeding speed is increased by 10%, not only the friction speed will increase by 10%, but also the tension will increase by the same amount. The prevention of scum is extremely important and strongly desired because the high contact pressure causes guide friction and the amount of scum increases, which significantly lowers weaving efficiency (significantly lowers productivity). Conventionally, scum generated by friction with such guides is caused by adhesives and oligomers present on the surface of polyester fibers treated with epoxy compounds, except under severe friction conditions where the polymer is scraped. It is thought that this is because the particles accumulate on top. Therefore, oil agents that reduce stickiness are generally considered to be advantageous in reducing scum, and agents that are as hydrophobic as possible have been studied to reduce frictional resistance and hygroscopicity. In general, in the field of woven and knitted fabrics, it is a well-known fact that a non-aqueous oil mainly consisting of food oil is added to the fabric before woolly processing or weaving. However, there are limits to scum prevention solely from this perspective. In particular, in the case where a polymer mainly composed of an epoxy compound has been applied in advance to modify the fiber surface and an adhesive layer is formed on the surface, it is necessary to significantly increase the amount of additional oil. If more than 3 parts by weight of oil is added per 100 parts by weight of fiber, not only guides but also looms and knitting machines will be contaminated with the oil, which is not practical. The inventors of the present invention focused on the fact that the scum generated by the friction between the guides and synthetic fibers is mainly composed of epoxy polymers and oligomers, and after conducting various studies from the perspective of adding oil, it was surprisingly found that scum was not generated in the past. The present invention was achieved by discovering that the amount of scum on the guides can be significantly reduced by applying water to the threads just before friction with the guides occurs, which was thought to increase. That is, the present invention provides the epoxy surface-treated polyester yarn before friction occurs between the polyester synthetic fiber whose surface has been surface-treated with an oil agent containing an epoxy compound and the guides used in high-order processing.
This is a method for preventing friction scum on polyester synthetic fibers, which is characterized by adding 0.1 part by weight or more of water per 100 parts. In the present invention, guides are objects that are rubbed against the yarn in order to regulate the running of the yarn, and correspond to parts that are rubbed during the yarn twisting, knitting and weaving processes. In the present invention, scum generated from friction between synthetic fibers and guides is prevented by adding 0.1 parts by weight or more of water to 100 parts by weight of fibers before friction occurs between synthetic fibers and guides. In particular, it is important that the moisture content of the fibers at the friction site is higher than the equilibrium moisture content of the atmosphere. For this reason, the lower limit of the amount of water applied using the roller water supply method is regulated to be 0.1 parts by weight/100 parts by weight of fibers. The upper limit of the amount of water applied is preferably 10 parts by weight or less per 100 parts by weight of fiber. If the amount of water applied increases excessively, problems such as rusting of machinery will occur due to the water, so it is industrially preferable to suppress the amount of water applied as much as possible within the range that prevents scum. In carrying out the present invention, water is applied to 100 parts by weight of the fibers using a roller method, spray method, etc. in the unwinding part of the yarn package used for higher processing steps, such as twisting, weaving, and knitting. It may be added in an amount of 1 to 5 parts by weight. By applying water in this manner, the water application conditions of the method of the present invention can be satisfied in all of the parts that are subjected to friction until the end of twisting, weaving, and knitting. Although the effect of adding water according to the present invention, that is, the mechanism for preventing scum, has not yet been confirmed, it is likely that water and frictional heat improve the compatibility between epoxy polymers, oligomers, and oil agents, resulting in the formation of sticky substances and oligomers at the friction site. This is thought to be due to a decrease in scum precipitation. As described above, according to the present invention, there is no need to increase the amount of additional oil, and by simply applying water, which is inexpensive and easy to handle, to the thread, scum generation due to guide friction at high speed and high contact pressure can be prevented, and high-speed machining can be performed. It is meant to be. The method of the present invention will be described in detail below with reference to Examples. <Example> Tetron woven yarn pretreated with epoxy compound
Using 1000de/192fil, unwind the raw yarn from a 5Kg package and pass it through an S-type convenser (manufactured by Fukui Kiki) while adjusting the yarn tension to 20g.
Run at 300m/min for 30 minutes. On the other hand, a rotating roller with its lower part immersed in water is installed between the package cage and the convensator, and after the yarn is brought into contact with the roller, the yarn tension is adjusted to 20 g using the convensator, and the yarn is run at 300 m/min for 30 minutes. . The amount of water applied is adjusted by the number of roller rotations. After the run, the scum condition on the conventor was observed and the results shown in Table 1 were obtained.

[Table] From this result, it is recognized that although almost no water is applied in one rotation of the oiling roller (OR), scum is significantly reduced compared to the one that does not apply water (OR = 0).
No scum generation was observed when water was applied in Examples 2 and above. Also, the rotation speed of the OR was extremely increased.
With the 32 rpm version, there were problems such as water accumulating on the conventator, but up to OR = 16,
The yarn ran extremely smoothly with almost no noticeable water adhesion.
