Cationic polypropylene spinning oil prepn

Abstract

The present invention discloses one kind of cationic polypropylene spinning oil preparation and belongs to the field of chemical fiber spinning oil preparation technology. The cationic polypropylene spinning oil preparation consists of antistatic agent 2-10 wt%, smoothing agent 45-60 wt%, dispersant 5-20 wt%, bundling agent 5-20 wt% and stabilizer 2-5 wt%. The antistatic agent is cationic quaternary ammonium salt surfactant [RN(R1)(R2)(R3)]+X-, where, R is C10-C12 linear alkane, R1, R2 and R3 are C1-C3 alkyl group or H, and X is Cl or Br element. The present invention is suitable for compounding water solution of spinning oil with water possessing relatively high hardness for use in spinning polypropylene fiber, and has high oil film strength, high adhesiveness, homogeneous and stable oiling and capacity of endowing fiber with excellent performance.

Description

technical field [0001] The invention relates to a spinning finish for polypropylene fiber, in particular to a spinning finish for cationic polypropylene fiber, and belongs to the technical field of chemical fiber spinning finish. Background technique [0002] Polypropylene fiber is a hydrophobic polymer compound with no polar groups in its molecular structure, low hygroscopicity and strong static electricity. In the process of fiber spinning and texturing, the friction between fiber tows and the friction between fibers and mechanical equipment will generate static electricity, resulting in tow winding, wool, loosening, etc. Therefore, in the polypropylene spinning production process, In order to ensure the smooth spinning of fibers under certain conditions, improve fiber performance and fiber quality, and improve the quality of fiber products, spinning oil must be used. [0003] In order to reduce production costs, when preparing oil emulsions, gen...

Problems solved by technology

At present, polypropylene fiber oils are generally compounded with nonionic surfactants and anionic surfactants. The Chinese invention patent "Polypropylene Spinning Oil and Its Manufacturing Method" (CN1257950) discloses a silicone oil, high-grade Alcohol, higher acid, cetyl alcohol phosphate potassium salt, amphoteric phosphate ammonium salt, etc. are used as polypropylene spinning oil as additives. Since its constituent components are mainly nonionic and anionic surfactants, Ca in water 2+ , Mg 2+ Metal ions such as metal ions can combine with anionic surfactants in the oil, such as phosphate salts, to form insoluble and water-insoluble precipitates, which affect the antistatic performance of the oil and the emulsification and dispersion of the oil, and then affect the fiber resistance. Due to static electricity and friction characteristics, wool and broken ends are prone to occur in the process of spinning and post-elastic deformation, resulting in poor winding formation and low rate of high-quality products. It is difficult to adapt to the use requirements of polypropylene spinning technology, and sometimes the fibers are not It will not be able to produce, which will bring economic losses to chemical fiber manufacturers
