| titleOfInvention | A kind of method utilizing PET to produce flat filament |
| abstract | The invention discloses a kind of preparation method utilizing PET to produce flat filament, comprise the steps: 1) PET polyester slice, mix with toughener, antioxidant, filler, and section after drying enters screw extruder；2) in screw extruder, under the temperature conditions of 250～290 DEG C, dried section is carried out melt blending, chain extending reaction occurs；3) described melt is under the effect of adsorption system, obtains sheet after cooling；4) sheet in step 3) being heated, stretched, it is thus achieved that nascent flat filament, wherein stretching is divided into two steps；5) described nascent flat filament cools down further, flattens, then make eliminostatic to process, finally carry out rolling, compared with prior art, it is an advantage of the current invention that: the PET flat filament hot strength that the present invention produces reaches more than 200MPa, elongation at break is less than 50%, can apply to produce high performance woven bag and container bag field. |
