Abstract
The properties of PE/PET bicomponent spunbonded nonwovens with various areal density in certain processes were tested and analyzed. The areal density of samples can be changed by adjusting the speed of net belt. The evacuated materials which are discussed in this paper are PE/PET bicomponent spunbonded nonwovens whose areal density are 15 g/m2, 20 g/m2, 30 g/m2, 40 g/m2, 50 g/m2, 60 g/m2, 70 g/m2and 82 g/m2. The tensile strength, evenness and flexibility of the samples were measured. Also, the flexibility of PET spunbonded nonwoven were compared with the PE/PET bicomponent spunbonded nonwoven. The conclusion is that the strength, unevenness increase when the areal density increases, but the flexibility decreases. the flexibility of PE/PET nonwoven is superior to PET nonwoven, especially low areal density.
