Abstract
Abstract
The mechanical properties of conjugated-spun and laser drawn poly(ethylene terephthalate) (PET) fibers were investigated. The as-spun fibers used for the laser drawing were made by conjugated melt spinning with the copolymer of p-hydroxybenzoicacid and 2-hydroxy-6-naphthoicacid or polystyrene. The PET fibers prepared by conjugated spinning could be laser drawn to higher draw ratios under lower drawing stresses. The drawn fiber could be re-drawn up to a higher total draw ratio. Thus, a PET fiber having a tensile strength of 1.14 N/tex could be produced.
