Abstract

Ράμματα θερμοπλαστικών μονονημάτων που έχουν βελτιωμένη ευκαμψία και χαρακτηριστικά χειρισμού λαμβάνονται με μια διαδικασία τραβήγματος σύρματος τήγματος που περιλαμβάνει το στάδιο του τραβήγματος των νημάτων σε μια θερμαινόμενη ζώνη που διατηρείται σε μια θερμοκρασία επάνω από την θερμοκρασία τήξης του νήματος. Τα νήματα που προκύπτουν έχουν μεγαλύτερη επιμήκυνση και χαμηλότερο μέτρο ελαστικότητας από το συγκρίσιμο νήμα που λαμβάνεται χωρίς το στάδιο τραβήγματος υπό θέρμανση, και χαρακτηρίζονται από μια κρυσταλλική δομή που είναι περισσότερο σε υψηλό βαθμό διαταγμένη στον πυρήνα του νήματος απ'ότι στην περιβάλλουσα δακτυλιοειδή περιοχή. ω
