1. IntroductionBecause of the rapid growth of this technology, the global inventory of air-jet spinning equipment has consistently increased since the start of the 21st century. The spinning cup is a key component of air-jet spinning machines. To preserve the longevity of the air-jet spinning machines and fulfill their high-speed and high-production spinning needs, it is imperative to consistently enhance the material performance, manufacturing precision, and surface quality [1].

3.4. Phase Structure and Chemical CompositionFigure 7 is the X-ray diffraction spectrum of the Ni-P-nanoPTFE composite coating prepared using the five groups of PTFE emulsion concentrations. Figure 7 shows that the XRD spectra of the five groups of experiments have essentially the same shape, with sharp peaks appearing near the left side of 2θ = 20°, and steamed-bun-shaped diffuse diffraction peaks appearing near 2θ = 45°.
