Abstract:In order to study the effect of doubling and twisting process of sorona filament on elastic resilience，sorona filament of 3.33 tex/20 F and 5.56 tex/48 F are doubled and twisted on a doubling and twisting machine，the tensile properties and load elasticity of doubled and twisted yarns are analyzed by changing twist factor and pretension.Taking the elastic resilience and breaking strength of the doubled and twisted yarns as evaluation indexes，the doubling and twisting process is optimized by orthogonal test.It is pointed out that the twist factor and pretension are the main factors affecting the properties of doubled and twisted yarns and the structure of filament is more compact after doubling and twisting，and the elasticity and breaking strength are improved.When the twist factor is 375 and the pretension is 7.5 of sorona filament doubled and twisted yarn，the tensile and elastic properties of doubled and twisted yarn are the best.
Key Words:sorona filament；doubling and twisting；twist factor；pretension；breaking strength；breaking elongation；elastic resilience
