Effect of oiling treatment process on Lyocell fiber properties

In order to optimize the oiling processing of Lyocell fibers and improve its subsequent processing performance,Lyocell fibers were oiled under the condition of constant temperature leaching and constant pressure pressing.The effects of oil concentration,oil mixing ratio and oil temperature on the film forming,friction performance,antistatic performance and mechanical properties of Lyocell fibers were studied in detail by means of scanning electron microscopy,strength and elongation analysis,friction factor analysis and volume resistance analysis.The results showed that when the oil concentration was 6 g/L,non-ionic surfactant content was 31%,the oil temperature was 65℃,the thickness of oil agent layer form on the fiber surface was even and the fiber smoothness was good.The mechanical properties of fiber were excellent.Fiber breaking strength was 3.92 cN/dtex,elongation at break was 11.38%.Antistatic properties and cohesiveness of fibers were best.Volume resistance of fiber was 5.66×10⁹Ω·cm and cohesiveness between fibers was 223.0 cN.
