Fiber e entsoeng hape ea polyester (PET) ke eng?
Ke hore, litšila tsa polyester (PET) polymer le litšila tsa polyester (PET) li sebelisoa hape 'me li sebetsoa hore e be fiber ea polyethylene terephthalate.
Ho ea ka mantsoe a layman, fiber ea polyester e sebelisoang hape (eo ka morao e bitsoang polyester e sebelisoang hape) e bolela polyester e tsosolositsoeng (joalo ka li-bottle flakes, foam, litšila tsa silika, litšila, masela a litšila, joalo-joalo) tse entsoeng ka mekhoa ea ho tsosolosa.
