ドスカムの防止方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preventing guide scum that occurs when synthetic fibers are rubbed against guides.

合成繊維の製造に際しては、ガイド類との摩擦を低減さ

ノマーも存在する。When producing synthetic fibers, a fiber treatment agent called K (oil agent) is applied to reduce friction with guides and prevent static electricity generation. Synthetic fibers are manufactured by turning polymers polymerized from general fibers into threads, so not only polymers but also oligomers and monomers are always present on the fiber surface.

ころである。However, when synthetic fibers with such a surface are rubbed against the guides, not only the oil adheres to the guides, but also surface oligomers, nitrates, and scraped polymers are deposited on the guides. . Such deposits are collectively called scum, and in recent years, as processing speeds have increased to improve productivity, the increase in scum has become a problem. for example,
When manufacturing floating woven products using a rapier loom, if the weft feeding speed is increased by 0%, only the friction speed will increase by 10%.
The tension does not rise to the same extent, but the tension also rises to the same extent, resulting in high speed and high contact pressure guide friction, and the number of yarn breaks due to troubles due to scum generation (insufficient weft transfer by rapier) increases significantly compared to the conventional method. Therefore, prevention of friction scum in industrial production is extremely important and highly desirable.

従来このようなガイド類との摩擦によっ【発生するスカ

では親水性の強いオリゴマーを押さえるため虻、出来る
だけ疎水化し、摩擦低減と吸湿性低減から検討されてき
た。Conventionally, scum generated by friction with such guides is thought to be caused by oil and oligomers present on the surface of synthetic fibers depositing on the guides, except under severe friction conditions where the polymer is scraped. . Therefore, oil agents that reduce surface oligomers are considered to be advantageous in reducing scum, and in fact, in synthetic fibers such as polyester and polyamide, they are made as hydrophobic as possible to suppress the highly hydrophilic oligomers, reducing friction and moisture absorption. It has been considered since.

このような観点から織編物分野では、鉱物油を主体とし
た非水系油剤をウーリー加・１前又は織編成前に追油す
ることは良く知られた事実である。From this point of view, in the field of woven and knitted fabrics, it is a well-known fact that a non-aqueous oil based mainly on mineral oil is added before woolly addition or knitting.

しかしこのような観点からだけでのスカム防止忙限度が

追油量を著しく増す必要が生じるが、繊維１００重量部
忙対Ｌａ重量部以上も追油するよ５になるとガイド類の
みならず織機、１１機も油剤で汚染されることになり実
用上好ましくない。However, there are limits to scum prevention from this perspective alone. For example, if there is an extremely large amount of surface oligomers, or if a polymer such as epoxy has been applied in advance to modify the fiber surface and an adhesive layer is formed on the surface, it will be necessary to significantly increase the amount of additional oil. If more than 5 parts by weight of La per 100 parts by weight of fiber is added, not only the guides but also the loom and the loom will be contaminated with the oil, which is not preferred in practice.

ムが著しく減少することを見い出し本発明に到達したも
のである。The inventors of the present invention focused on the fact that the scum produced by the friction between the guides and synthetic fibers was mainly composed of oligomers, and after conducting various studies from the perspective of adding oil, they were surprised to find that the scum produced by the friction between the guides and synthetic fibers was thought to increase the occurrence of scum. The present invention was achieved by discovering that by applying water to the yarn just before friction with the guides occurs, the amount of scum on the guides is significantly reduced.

即ち本発明は合成繊維とガイド類との摩擦が生じる前に
繊維１００重量部に対し０．１重量部以上の水を付与、

ある。That is, in the present invention, before friction occurs between the synthetic fibers and the guides, 0.1 parts by weight or more of water is applied to 100 parts by weight of the fibers,
This is a method for preventing friction scum on synthetic fibers, which is characterized by sipping.

に有効である。Synthetic fibers in the present invention include, for example, polyester fibers,
Examples include polyamides, polyacrylics, polyurethanes, polyolefins, and polyvinyl chloride, but polyesters and polyamides obtained by melt spinning are preferred. Furthermore, even among polyester and polyamide synthetic fibers, especially those to which epoxy treatment agents are attached in order to give them easy adhesion and antistatic properties, the surface tackiness increases, especially the generation of scum. Particularly effective.

、　　′ 本発明において、ガイド類とは糸の走行を規制するため
に糸と摩擦される物体であり、撚糸。, ' In the present invention, guides are objects that rub against the yarn in order to regulate the running of the yarn, and are used for twisting yarn.

な範囲で出来るだけ水付与量を抑える方が工業的には好
ましい。In the present invention, scum generated due to friction between the synthetic fibers and the guides is prevented by applying water in an amount of 0.1 parts by weight or more per 100 parts by weight of the fibers before friction occurs between the synthetic fibers and the guides. In particular, it is important that the moisture content of the fibers in the friction area is higher than the equilibrium moisture content of the atmosphere. From this, the lower limit of the amount of water applied by the roller set water supply 1° method is 0.1 parts by weight/1 fiber.
00 parts by weight of water is regulated. The upper limit of the amount of water applied is 10 parts by weight or more per 100 parts by weight of fiber.
゛ is preferred. 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.

明方法の水付与条件を満たしうる。In carrying out the invention, the twisted yarn, a1! In the unwinding part of the yarn package used for weaving and knitting, a set of rollers, a set of sprayers, etc. are used to add 1 part of water to 1'00 parts by weight of fiber from K.
~5 parts by weight may be added. By applying water in this manner, the water application conditions of the method of the present invention can be satisfied in all the parts that are subjected to friction until the end of twisting, weaving, and knitting.

ではないかと考えられる。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 of monomers, oligomers, and oils, causing scum such as oligomers to precipitate at the friction site. It is thought that this is because φ decreases.

速加工を可能にするものである。As described above, according to the present invention, there is no need to increase the amount of additional oil,
By simply applying water, which is inexpensive and easy to handle, to the yarn, scum generation due to guide friction at high speed and under high contact pressure can be prevented and high-speed processing can be performed.

Using de/19zfil, unwind the raw yarn from 5 to 9 packages, pass it through an S-con S type compensator (manufactured by Fukui Kiki), and adjust the yarn tension to 20g.A O0? +
Run at 1/min for 30 minutes. On the other hand, a rotating roller with its lower part immersed in water is installed between the package and the compensator, and after the yarn is brought into contact with the roller, the yarn tension is adjusted by 2 og with the compensator, and the yarn is run at 300 TrL/min for 30 minutes. . The amount of water applied is adjusted by the number of roller rotations. When the scum condition on the compensator was observed after running, the results shown in Table 1 were obtained.

In addition, with the extremely high KOH rotation speed of 321%, there were problems such as water accumulating on the compensator, but up to OR = 16, the water adhesion was hardly noticeable and the thread was extremely smooth. It ran.
