| Abstract: | The structural characteristics of the polymer feedstock, polyurethane and polyether ester, practicable for elastic fiber melt spinning were described. It was pointed out that it was a good way to increase the fiber's strength and enhance the steady|state spinning that prepolymer was adopted to screen the melt from visco|elasticity. The dried|and|hot nitrogen chips drier and low|capacity|and|less|part packaged spinning unit with mixer as well as parallel spinning that had low spinning speed, high superfeed, low|temperature|and|high|moisture cooling and low winding tension were introduced. |
