| titleOfInvention | A kind of method utilizing the PET bottle manufacture weaving long filament of recovery |
| abstract | The invention discloses a kind of method utilizing the PET bottle manufacture weaving long filament of recovery, comprising: by the PET bottle of recovery through fragmentation, washing and drying, obtain PET fragment; PET fragment is joined in parallel equidirectional two-screw extruder, through melt blending and filtration, obtain melt; Melt is sent into closed reaction vessel, nitrogen injection in closed reaction vessel, add dihydroxylic alcohols, then add aluminium-based catalyst under nitrogen stream is agitated, mix and blend carries out alcoholysis reaction, obtains the melt after processing; Melt after process is sent to pressure-resistant reaction vessel through closed conduit from closed reaction vessel, vacuumize after airtight, negative pressure stirs carries out polycondensation reaction, after melt characteristic viscosity reaches 0.65dl/g-0.70dl/g, by the wire vent of mouth mould, after height spins, obtain weaving long filament, the weaving long filament of the method manufacture is adopted to have excellent and stable mechanical property, and simple to operate, higher production efficiency can be obtained, be suitable for suitability for industrialized production. |
