Studies On TCS Microporous Man-made Yarn-kind New Synthetic Fibre

Abstract: The formation technologies, the structure and properties of TCS microporous man-made yarn-kind new polyester fibre which was spinned in TCS with some micrometallic-oxide have been studied. The results indicate that the rheological behaviour and spinnability of commixed polyester melt, and the structure and properties of the fibre, are relative to the spinning temperature, melt pressure, microporpus size for spinning, formation conditions, thermo-vascellum temperature, thermo-vascellum position and rolling speed, besides the viscosity of polyester cuts, coacervation particles, adding amount and size of micrometallic-oxide. At the same time, by studying the micro-thought surface form, the structure of aggregation state, mechanics characteristics and properties of TCS microporous man-made yarn-kind new polyester fibre, the changing regularity of micro-thought structure during the fibre formation, and the internal linkage between the formation condition and the micro-thought structure and properties have been researched, too. So the results could provide the bases theory and reference for developing the TCS fibre formation technologies.
