| Abstract:In this paper, 5 kinds of PET fibrid prepared in laboratory were observed under microscope, their specific surface area and fractionation were tested, and their papermaking property was also studied. The result showed that the distribution of PET fibrid’s constituent was mainly in between 16 and 30 mesh, the amounts of this part accounted for 90.7%, 90%, 84.8%, 80.6% and 65.6% respectively as the shearing rate increasing. The length was mainly in between 0.596 mm and 1.192 mm, the proportions of fines passed the sieve accounted for 1.9%, 2.7%, 3.4%, 10.4% and 25% respectively and the specific surface area increased as the shearing rate increasing. When the ratio of PET fibrid∶chopped fiber=5∶5, tensile index and burst index of the paper were the maximal, when PET fibrid∶chopped fiber=3∶7, tear index of the paper was maximal． |
