The invention provides a zein fibre, which is provided with good spinning and predominant taking performance, and the producing method. Purifying zein, which is extracted from the stock that is the residue fluid after extracting corn starch, is melt in sig water. It is mixed with various activating agents such as glyoxal. Under the effect of certain temperature, density, pressure and given various activating agent, original fluid with certain density is make up, Zein fibre is slubbed by the technology of wet method and deaeration spinning is completed. Zein fibre is provided with comfortable hand feeling, good gloss, thin single titer which can be slubbed to 0.7dtex, light of specific weight and so on. It can be knitted as high-grade cloth material which is various untra-thin or thickening. |
