Pure soybean protein yarn and creep properties of soybean/spandex core-spun yarn were tested and analyzed. Basic model of yarn viscoelastic body was analyzed and described. It can be concluded that a four-element model can describe the creep process of pure soybean protein yarn and soybearr/spandex core-spun yarn more accurately. According to the measured data, the fitting equation of yarn creep elongation was built, and characteristic parameters of four-element model were got by further analysis. The pro- cessin,~ narameters which influence creep properties of soybearrCspandex core-spun yarn were studied and explained deeply and rationally.
