Comparative Study of Physical, Chemical, and Dyeing Performances of PET, PTT, and PET/PTT Bicomponent Filaments

The chapter is devoted to presenting an open review about a comparative study on physical and chemical properties of used polyester types such as polyethylene terephthalate (PET), poly(trimethylene terephthalate) (PTT), and bicomponent filaments of PET and PPT. A general summary of polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), and polyethylene naphthalate (PEN) were described their reaction mechanism as well as by the determination of important properties in terms of morphological, mechanical, chemical, and thermal behavior. The second part of this work was allowed to the description of the synthesis and characterization as well as the advantage of use of bicomponent polyester filaments in industrial scale. The third part was focused especially on bicomponent filaments (60% PET, 40% PTT) in terms of spinning and their effect on dyeing process.
