The main function of the general filament oiling agent is to enable the fiber after oiling to be wound smoothly, the filament tube is well molded, and the broken filaments and ends are reduced in the drawing process to ensure normal drawing, so the oiling agent is required to have good antistatic property, moderate lubricating property and fiber cohesion.
Along with the development of industrial technology, the diameter of the superfine denier yarn manufactured at present is smaller than 7.2um, the superfine denier yarn is suitable for weaving high-density waterproof breathable fabrics, and the manufactured fabric is popular in the market due to the excellent product performance. In the process of spinning, as the fineness of each monofilament is smaller, the strength of the superfine denier fiber is smaller, and in the process of drawing and winding, the friction of the fiber by a plurality of drawing rollers, winding rollers and the like can possibly cause the breakage of the monofilament, so that the fuzzing phenomenon of the superfine denier fiber is caused. This is caused by friction between the fiber and the rollers such as the drawing roller and the winding roller, and if the adhesion strength of the oiling agent on the fiber surface is insufficient under the premise of ensuring the surface smoothness of the components such as the drawing roller, the oiling agent on the fiber surface is reduced in the drawing or velvet winding process, so that the risk of cracking and fuzzing is increased.
