Effect of filament spread behavior on the structure of composite yarns

In this study, three defined spreading types of polyester filaments-evenly divided, one-sided, and tight section types-acre adopted to analyze the twi sting of model assemblies. The experimental results reveal that filament sp reading behavior is the main factor influencing the structure of composite yarns. If the polyester multifilament spreads effectively and divides evenl y after passing through a spreading electrode, the percentage of the unifor mly distributed area of the composite yarn structure will be 43.0%.
