摘　　要：To accurately evaluate and predict the covered effect of cowrapped yarn,a novel characterization is performed by covered ratio and fineness. Polyimide / metal wire co-wrapped yarn which was designed for applications in aerospace and composites was developed through hollow spindle spinning process. Core yarn speed,hollow spindle rotating speed,and wrapping yarn twist were selected as three main factors that affected spinning process. An empirical model indicating relationship between spinning parameters and covered effect was established based on response surface methodology( RSM). The results show that wrapping yarn twist contributes greatly to smooth wrapping process. Core yarn speed and spindle rotating speed are significant impact factors of covered effect and they interact significantly in covered ratio, but indistinctively in fineness.To accurately evaluate and predict the covered effect of cowrapped yarn,a novel characterization is performed by covered ratio and fineness.
