Abstract:The melt direct spinning process of 83 dtex/144 f ultrafine polyester POY was studied.The effects of spinpack,quenching method,collection finishing height and winding speed on the product quality were discussed.The results showed that the polyester POY of 83 dtex/144 f can be obtained with the breaking strength of 2.55-2.65 cN/dtex,breaking elongation 115.9%-120.0%,yarn irregularity 1.40%-1.60% under the conditions as followed: spinning temperature 289-291 ℃,spinneret hole diameter 0.17 mm and length 0.54 mm,spinpack sea sand quantity 60-80 mesh/150 g and 40-60 mesh/120 g,external circular quenching air pressure 25-28 Pa,oil nipple height 700 mm,oil pick-up 0.45%.
Keywords:polyethylene terephthalate fiber  direct spinning  ultrafine  pre-oriented yarn  production process
