• the present invention relates to a process for manufacturing or processing a synthetic fibrous multifilament or monofilament (particularly, an anti-collar process). This is a spinning oil applied immediately after melt spinning of Mido fiber.
• the oil for treating synthetic fibers is often applied to the lemon as an aqueous emulsion or aqueous solution.
• the foam can be adjusted to give it to synthetic fibers or foaming occurs in the circulation system of the emulsion or aqueous solution (between the stock tank and the oiling device). If the foam is introduced into the oil bath, it may interfere with the adhesion of oil to the fibers.Also, even if foam is not formed in the circulatory system, oil glows during oiling. Very stable fine bubbles are easily generated in the upper thread path. In the same way, adhesion of the oil agent to the fiber is hindered.
• This phenomenon is particularly apparent in high-speed spinning at a winding speed of more than 2000 m / min.
• the problem of foaming occurs not only in the spinning process but also in the processing process, which may be a problem.
