| titleOfInvention | Melt direct spinning preparation method of extinction PET (polyethylene terephthalate) fibers |
| abstract | The invention relates to a melt direct spinning preparation method of extinction PET fibers, wherein functional master batches are added on line in the PET melt direct spinning process to prepare the extinction PET fibers, the functional master batches are prepared by melting and blending PET slices and hollow porous microspheres coated with titanium dioxide nanoparticles, the hollow porous microspheres coated with the titanium dioxide nanoparticles mainly comprise the titanium dioxide nanoparticles and cross-linked spheres coated on the surfaces of the titanium dioxide nanoparticles, the cross-linked spheres are hollow inside and porous on the surfaces and have cross-linked structures, the cross-linked structures are formed by cross-linking copolymer molecular chains containing styrene and bifunctional dimethacrylate monomer structural units, and the titanium dioxide nanoparticles and the cross-linked spheres are connected through covalent bonds. The method has simple and convenient process, and the prepared fiber has the advantages of excellent mechanical property, good extinction effect, small addition amount of titanium dioxide, uniform dispersion and the like, and has wide application range. |
