A one  dimensional single filament model developed by  previous workers is used to construct a  multifilament model which enables a conservative  estimate to be made on the effects of heat transfer  limitations on the quality of PET yarn. Properties  modelled include crystallinity, viscosity,  temperature, velocity, fibre diameter and force.  Variables investigated include quench air  temperature and velocity, polymer extrusion rate  and temperature as well as fibre take-up speed.   Results showed quench air flow rate to have the  largest influence on final property uniformity. Low  polymer extrusion rates resulted in a lower degree  of non-uniformity in final fibre properties. The  model developed showed non-uniform quench air  thermal gradients to have adverse effects on the  quality of as-spun yarn.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843378017\"\u003e\u003ch3\u003eThe effects of heat transfer limitations on the quality of PET yarn produced during melt spinning.\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843378017","offer_id":39497097773149,"sku":"9783843378017","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/1a25509a-33a7-43b0-bce5-8e4ff6506992.jpg?v=1769839163","url":"https:\/\/shop.autorenwelt.de\/en\/products\/two-dimensional-modelling-of-pet-melt-spinning-von-tyrone-kotze","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
